1. Which newly admitted client on the psychiatric unit does the nurse see FIRST?
A. Client with depression who says life feels pointlessThis client expresses feelings of hopelessness, which is a significant indicator of potential suicidal ideation and a common symptom of depression. While concerning and requiring comprehensive assessment and intervention to ensure safety and provide support, the statement "life feels pointless" typically represents a passive form of suicidal ideation rather than an immediate, active plan or imminent action, especially in a newly admitted client who is already seeking help on a psychiatric unit. The nurse would prioritize a full suicide risk assessment, but another client presents with more acute, immediate danger signals.
B. Client who suddenly appears calm and is giving away belongingsA sudden shift from agitation or distress to calmness, coupled with giving away belongings, is a classic and highly alarming red flag for imminent suicide risk. This behavior often indicates that the client has made a decision to end their life and has found a sense of peace or resolution in that decision, or is "putting their affairs in order." This client is at an extremely high risk for attempting suicide and requires immediate, direct intervention to ensure their safety, making them the top priority for the nurse.
C. Client with panic disorder requesting a PRNA client with a panic disorder experiencing anxiety and requesting a PRN medication is in distress and requires nursing intervention to alleviate their symptoms. However, panic attacks, while acutely uncomfortable and debilitating, are generally not life-threatening in themselves, and the client is actively seeking help to manage their symptoms. While the nurse would respond promptly to provide comfort and medication, this situation does not pose the immediate, direct threat to life that active suicidal planning does.
D. Client with bipolar disorder pacing the hallwayA client with bipolar disorder who is pacing the hallway may be experiencing increased agitation, anxiety, or escalating manic symptoms, which require nursing assessment and de-escalation strategies. Pacing can be a manifestation of internal restlessness, psychomotor agitation, or an inability to relax, which are common in various mental health conditions. While this client requires intervention to manage their symptoms and prevent further escalation, their behavior does not indicate an immediate and direct threat to their life comparable to active suicidal planning.

2. The nurse finds the chest tube disconnected from the drainage system. What is the FIRST action?
A. Clamp the tube near the chestClamping the chest tube near the chest is generally contraindicated because it can lead to a tension pneumothorax. When the tube is clamped, air or fluid that continues to leak from the pleural space has no exit, causing positive pressure to build up, which can collapse the lung, shift the mediastinum, and compromise cardiac output. While temporary clamping might be considered in very specific, controlled circumstances (e.g., changing the drainage system), it is not the immediate, safe first action for an accidental disconnection in an emergent situation.
B. Submerge the tube end in sterile waterSubmerging the disconnected end of the chest tube in 1 inch of sterile water creates a temporary water seal, which prevents atmospheric air from entering the pleural space and causing a pneumothorax, while allowing air and fluid to escape. This action immediately re-establishes the crucial negative pressure environment necessary for lung re-expansion and prevents life-threatening complications like tension pneumothorax. This is the critical first intervention to maintain the integrity of the closed chest drainage system and protect the patient.
C. Call the provider immediatelyWhile calling the provider is an important step that should be done promptly after stabilizing the patient, it is not the FIRST action. The nurse's immediate priority is to prevent acute, life-threatening complications that can arise from the disconnection, such as a pneumothorax or tension pneumothorax. Stabilizing the patient's immediate physiological status by re-establishing a water seal takes precedence over notification, as the provider cannot intervene until the nurse has addressed the immediate danger.
D. Reinforce the dressing with tapeReinforcing the dressing with tape would not address the problem of the disconnected chest tube from the drainage system. The dressing covers the insertion site on the chest wall and is designed to maintain an occlusive seal and prevent infection, but it does not play a role in the function of the drainage system itself. This action is irrelevant to the immediate danger posed by a disconnected tube, which is the potential for air entry into the pleural space.

3. A client's potassium is 6.8 mEq/L with peaked T waves. Which order does the nurse do FIRST?
A. Sodium polystyrene sulfonate POSodium polystyrene sulfonate (Kayexalate) is an ion-exchange resin administered orally or rectally to bind potassium in the gastrointestinal tract, promoting its excretion in feces. While effective in lowering potassium levels, its onset of action is relatively slow, taking hours to produce a significant effect. In a client with severe hyperkalemia (6.8 mEq/L) and electrocardiogram (ECG) changes like peaked T waves, which indicate imminent cardiac instability, a more immediate intervention is required to stabilize the cardiac membrane. Therefore, while it is a long-term treatment for hyperkalemia, it is not the first intervention for a client experiencing acute cardiac manifestations.
B. IV calcium gluconateIntravenous calcium gluconate does not lower serum potassium levels; instead, its primary action is to stabilize the myocardial cell membrane. By directly counteracting the cardiac effects of hyperkalemia, calcium gluconate reduces myocardial excitability and the risk of life-threatening dysrhythmias, such as ventricular fibrillation or asystole, which are indicated by the peaked T waves. Given the critical potassium level of 6.8 mEq/L and the presence of ECG changes, cardiac membrane stabilization is the most immediate and life-saving intervention. This action buys time for other potassium-lowering treatments to take effect and prevents potentially fatal cardiac events.
C. Regular insulin with D50Regular insulin, often given with dextrose 50% (D50) to prevent hypoglycemia, promotes the intracellular shift of potassium, thereby lowering serum potassium levels. This treatment is very effective and has a relatively rapid onset of action, typically within 15-30 minutes. However, its primary goal is to shift potassium, not to directly stabilize the cardiac membrane. While crucial for bringing down the potassium level, the immediate priority for a client with cardiac abnormalities (peaked T waves) is to protect the heart from further electrical instability.
D. Albuterol nebulizerAlbuterol, a beta-2 adrenergic agonist, can promote the intracellular shift of potassium by stimulating the sodium-potassium pump. While it can lower serum potassium levels, its effect is generally less potent and predictable than insulin and dextrose, and it also carries the risk of side effects like tachycardia. Similar to insulin and dextrose, albuterol helps to redistribute potassium from the extracellular to the intracellular space, but it does not directly stabilize the cardiac membrane. Therefore, it is not the first-line intervention for immediate cardiac protection in the setting of severe hyperkalemia with ECG changes.

4. A confused client is in soft wrist restraints. Which finding requires immediate nursing action?
A. Restraint tied to the movable side railTying a restraint to a movable side rail is a critical safety violation that can lead to severe injury or even death. If the side rail is lowered while the restraint remains attached, the client's limb could be hyperextended, entrapped, or caught, resulting in fractures, nerve damage, or strangulation. This practice contradicts fundamental principles of patient safety and restraint application guidelines, which mandate that restraints be secured to the stationary, non-moving part of the bed frame to prevent injury due to bed movement or changes in bed position. Immediate action is required to re-secure the restraint correctly and prevent potential harm.
B. Order renewed 8 hours agoAccording to Centers for Medicare & Medicaid Services (CMS) regulations and general hospital policy, orders for restraints in adult clients must be renewed at specific intervals, typically every 4 hours for violent/self-destructive behavior and every 24 hours for non-violent/medical reasons. An order renewed 8 hours ago is still within the acceptable timeframe for many non-violent restraint situations, which often allow for renewal every 24 hours. While the nurse should always be vigilant about the ongoing need for restraints and perform regular assessments, an order renewed 8 hours ago does not, by itself, indicate an immediate need for nursing action regarding the order's validity, assuming it falls within a 24-hour renewal cycle.
C. Client requesting a drink of waterA client requesting a drink of water indicates a basic physiological need that should be addressed promptly by the nursing staff. While this is an important part of client care and comfort, it does not represent an immediate safety hazard or a critical deviation from restraint protocols that would demand urgent intervention over a physical safety concern. The nurse should certainly provide water and assess for other needs like toileting or repositioning, but this request does not signify a life-threatening or injury-causing situation requiring immediate *corrective* nursing action regarding the restraint itself.
D. Two fingers fit under the restraintThe guideline that two fingers should fit under the restraint is a crucial safety measure to ensure the restraint is not applied too tightly, which could impair circulation or cause skin breakdown. If two fingers *can* fit under the restraint, it suggests that the restraint is applied appropriately, allowing for adequate circulation and preventing tissue damage. This finding indicates correct application and does not require immediate nursing action to adjust the restraint's tightness, but rather confirms proper technique. The nurse should continue to monitor skin integrity and neurovascular status distal to the restraint regularly.

5. The next bag of TPN has not arrived and the current bag is empty. The nurse should…
A. Hang 0.9% normal salineHanging 0.9% normal saline would replace the volume but would not provide a significant amount of glucose. This is important because TPN contains a high concentration of dextrose (glucose), and abruptly stopping it without an adequate glucose replacement can lead to rebound hypoglycemia, a dangerous drop in blood sugar levels. While 0.9% normal saline maintains intravenous access and hydration, it fails to address the metabolic need for glucose, which is crucial to prevent this adverse event. Therefore, this option is insufficient to prevent the major complication associated with interrupting TPN.
B. Hang 10% dextrose in waterHanging 10% dextrose in water (D10W) is the appropriate intervention when TPN is temporarily unavailable. TPN solutions are typically highly concentrated with dextrose (e.g., 20-25%), and D10W provides a sufficient amount of glucose to prevent rebound hypoglycemia, which can occur when the body, accustomed to a continuous high-glucose infusion, continues to produce high levels of insulin. This prevents life-threatening complications such as seizures, brain damage, and cardiac arrhythmias by maintaining stable blood glucose levels until the new TPN bag arrives. This intervention directly addresses the most immediate and critical physiological consequence of TPN interruption.
C. Flush the line and cap itFlushing the line and capping it would effectively discontinue the intravenous access and stop any glucose infusion. This action would immediately lead to rebound hypoglycemia because the body, which has been continuously receiving a high concentration of glucose from TPN, will continue to secrete insulin at elevated levels, quickly lowering blood glucose. Furthermore, completely stopping the infusion and capping the line could necessitate a new venipuncture later, causing unnecessary discomfort and potential complications for the patient. This approach neglects the metabolic needs of the patient.
D. Slow the pump to keep vein openSlowing the pump to keep the vein open (KVO) with the existing, now empty, TPN bag is not a viable or safe option. An empty bag means there is no solution left to infuse, and therefore, no glucose or nutrients are being delivered to the patient, leading to the same risk of rebound hypoglycemia as completely stopping the infusion. Attempting to infuse from an empty bag can also lead to air entering the line, posing a risk of air embolism, which is a serious and potentially fatal complication. This action does not provide any metabolic support and introduces a new safety hazard.
Correct answer: B. Option A: Hanging 0.9% normal saline would replace the volume but would not provide a significant amount of glucose.

6. A client on warfarin for atrial fibrillation has an INR of 5.8 with gum bleeding. The nurse anticipates…
A. Protamine sulfate IVProtamine sulfate is an antidote specifically for heparin overdose, by forming a stable salt with heparin that neutralizes its anticoagulant effect. Warfarin, on the other hand, exerts its anticoagulant effect by inhibiting vitamin K-dependent clotting factors (II, VII, IX, X), and therefore, protamine sulfate would have no therapeutic effect in reversing warfarin's action or reducing the INR. Administering protamine sulfate in this scenario would be ineffective and could potentially introduce unnecessary risks or side effects without addressing the underlying problem of excessive warfarin anticoagulation.
B. Vitamin K (phytonadione)Vitamin K (phytonadione) is the direct antidote for warfarin overdose because it is essential for the synthesis of vitamin K-dependent clotting factors (II, VII, IX, X) in the liver, which are inhibited by warfarin. With an INR of 5.8 and active bleeding (gum bleeding), the client is at high risk for serious hemorrhage, necessitating prompt reversal of anticoagulation. Administering vitamin K will replenish the body's stores, allowing for the production of functional clotting factors and thus reducing the INR and controlling the bleeding.
C. An extra warfarin doseAn extra warfarin dose would further increase the client's already dangerously high INR of 5.8 and exacerbate the risk of bleeding, as warfarin's mechanism of action is to *inhibit* clotting factors. The current INR indicates excessive anticoagulation, far above the therapeutic range (typically 2.0-3.0 for atrial fibrillation), making an additional dose counterproductive and potentially life-threatening. The nursing priority is to *reduce* the anticoagulant effect and prevent further hemorrhage, not to intensify it.
D. Platelet transfusionPlatelet transfusions are indicated for thrombocytopenia (low platelet count) or platelet dysfunction to improve hemostasis, but they do not reverse the anticoagulant effect of warfarin. Warfarin primarily affects the coagulation cascade by inhibiting clotting factors, not platelet function or count. While severe hemorrhage might eventually lead to consideration of factor concentrates or fresh frozen plasma to supply clotting factors, a platelet transfusion would not be the primary or most effective initial intervention for warfarin-induced coagulopathy.
Correct answer: B. Option A: Protamine sulfate is an antidote specifically for heparin overdose, by forming a stable salt with heparin that neutralizes its anticoagulant effect.

7. A client on metoclopramide reports restlessness and involuntary tongue movements. The nurse should…
A. Give the next dose with foodGiving metoclopramide with food does not mitigate or prevent the development of extrapyramidal symptoms, such as restlessness and involuntary tongue movements, which are neurological side effects. Food primarily affects gastric absorption and can sometimes reduce gastrointestinal upset, but it does not alter the drug's dopamine receptor blocking action in the central nervous system that leads to these adverse effects. Therefore, this action does not address the underlying cause of the client's symptoms and is an inappropriate intervention for neurological complications.
B. Encourage fluids and reassess in an hourEncouraging fluids and reassessing in an hour does not address the immediate and potentially serious nature of the client's symptoms, which are indicative of a drug-induced neurological reaction. Restlessness and involuntary tongue movements, particularly in the context of metoclopramide use, suggest extrapyramidal symptoms, specifically akathisia (restlessness) and tardive dyskinesia-like movements (involuntary tongue movements). These symptoms require immediate medical evaluation, as they can worsen or become permanent if the offending drug is continued, and merely increasing fluids will not resolve them.
C. Hold the drug and notify the providerRestlessness (akathisia) and involuntary tongue movements are classic signs of extrapyramidal symptoms (EPS), specifically tardive dyskinesia or acute dystonic reactions, which are serious adverse effects of metoclopramide due to its dopamine receptor blocking properties in the central nervous system. Continuing the drug can worsen these symptoms or even make them irreversible. Therefore, the nurse's priority is to immediately hold the medication to prevent further neurological damage and promptly notify the healthcare provider for assessment and potential intervention, such as prescribing an anticholinergic medication to counteract the EPS.
D. Document as an expected effectDocumenting restlessness and involuntary tongue movements as an expected effect of metoclopramide is inaccurate and potentially dangerous. While metoclopramide is known to cause extrapyramidal symptoms, these are serious adverse drug reactions, not benign or "expected" side effects that can be ignored. Failure to recognize and act upon these symptoms can lead to significant patient harm, including permanent neurological dysfunction like tardive dyskinesia, and is a breach of nursing responsibility to ensure patient safety and advocate for appropriate medical intervention.

8. Which client requires a negative-pressure room and an N95?
A. PertussisPertussis, also known as whooping cough, is primarily transmitted through respiratory droplets generated by coughing or sneezing. Therefore, clients with pertussis require droplet precautions, which involve a private room (or cohorting), a surgical mask for healthcare providers when within 3 feet of the client, and instructing the client to wear a mask when outside the room. A negative-pressure room and N95 respirator are not typically required because the disease transmission mechanism does not involve airborne particles that remain suspended over long distances.
B. Active tuberculosisActive tuberculosis (TB) is caused by *Mycobacterium tuberculosis* and is transmitted via airborne particles (droplet nuclei) that can remain suspended in the air for extended periods, traveling long distances. To prevent the spread of these airborne particles, clients with active pulmonary TB must be placed in an airborne infection isolation room (AIIR), which is a negative-pressure room designed to contain contaminated air. Healthcare providers caring for these clients must wear an N95 respirator or a powered air-purifying respirator (PAPR) to filter these microscopic airborne particles before inhalation, making this the correct choice for the required precautions.
C. C. difficile colitis*Clostridioides difficile* (*C. difficile*) colitis is a highly contagious gastrointestinal infection primarily transmitted through the fecal-oral route, often via contaminated surfaces or hands. Clients with *C. difficile* require contact precautions, which include a private room, gown and gloves for all interactions involving potential contact with the client or their environment, and meticulous hand hygiene with soap and water (alcohol-based hand rubs are ineffective against *C. difficile* spores). Neither a negative-pressure room nor an N95 mask is necessary, as the transmission mechanism does not involve airborne or droplet spread.
D. InfluenzaInfluenza is a viral respiratory illness typically spread through respiratory droplets produced when an infected person coughs, sneezes, or talks, similar to pertussis. For hospitalized clients with suspected or confirmed influenza, droplet precautions are recommended. This involves placing the client in a private room (or cohorting) and healthcare personnel wearing a surgical mask when working within 3 feet of the client. A negative-pressure room and N95 respirator are not indicated for routine care of influenza, as the primary mode of transmission is via larger droplets, not fine airborne particles.

A negative-pressure room and N95 respirator are not indicated for routine care of influenza, as the primary mode of transmission is via larger droplets, not fine airborne particles.
9. New sepsis alert: lactate 4.2, BP 84/48. Which intervention does the nurse complete FIRST?
A. Start broad-spectrum antibioticsInitiating broad-spectrum antibiotics is a critical component of sepsis management to combat the underlying infection. However, administering antibiotics *before* obtaining blood cultures can contaminate the cultures, leading to false negatives or masking the true causative organism. This delay in identifying the specific pathogen can hinder targeted antibiotic therapy and potentially lead to antibiotic resistance and prolonged treatment. Therefore, while essential, it should be done *after* cultures are drawn to ensure accurate diagnostic results.
B. Draw blood culturesDrawing blood cultures is the priority action in a patient presenting with suspected sepsis. Blood cultures are crucial for identifying the specific microorganism causing the infection, which then guides targeted antibiotic therapy. Obtaining cultures *before* administering antibiotics ensures the highest likelihood of isolating the causative pathogen, preventing false-negative results that could arise if antibiotics were started first. This diagnostic step is foundational for effective antimicrobial stewardship and improving patient outcomes in sepsis.
C. Begin norepinephrineBeginning norepinephrine is an intervention for septic shock to increase blood pressure and improve perfusion to vital organs by causing vasoconstriction. While the patient's blood pressure of 84/48 mmHg indicates hypotension consistent with septic shock, immediate initiation of vasopressors often follows fluid resuscitation, and in the *initial* phase, diagnostic steps like blood cultures are prioritized to identify the source of infection. Without identifying the pathogen, definitive treatment remains elusive, and starting vasopressors alone does not address the root cause of the septic state.
D. Insert an indwelling catheterInserting an indwelling catheter allows for accurate monitoring of urine output, which is a key indicator of renal perfusion and overall organ function in sepsis. It is also important for fluid balance management. While this is a valuable intervention in a critically ill patient, it is not the *immediate* priority over obtaining cultures to diagnose the underlying infection. Furthermore, inserting a catheter introduces a risk of infection, and this procedural step can be performed after the most critical diagnostic and initial therapeutic steps are underway.

10. A client gets regular insulin at 0730. When does the nurse watch most closely for hypoglycemia?
A. 0745 to 0800Regular insulin has an onset of action typically within 30 minutes to 1 hour after subcutaneous injection. Therefore, monitoring for hypoglycemia between 0745 and 0800, which is only 15 to 30 minutes post-administration, would likely be too early to observe the peak hypoglycemic effect. While some glucose lowering may begin, the insulin has not yet reached its maximum effect in the body, making severe hypoglycemia unlikely at this early stage. The nurse should be aware that the insulin is starting to work, but this is not the period of greatest risk.
B. 0930 to 1030Regular insulin reaches its peak effect, meaning the time when it is lowering blood glucose most potently, approximately 2 to 4 hours after subcutaneous administration. If the insulin was given at 0730, its peak action would fall between 0930 and 1130. Therefore, the 0930 to 1030 timeframe accurately represents the period when the insulin is maximally effective, significantly increasing the risk of hypoglycemia, especially if the client has not consumed adequate carbohydrates or is unusually active. This is the critical window for the nurse to monitor for signs and symptoms of hypoglycemia such as shakiness, sweating, confusion, and pallor.
C. 1400 to 1600Regular insulin typically has a duration of action of about 5 to 7 hours. While the insulin would still be active in the body between 1400 and 1600 (6.5 to 8.5 hours post-administration), its peak effect would have passed, and its action would be significantly diminished or nearing its end. Although a client could still experience hypoglycemia if their blood glucose was already low or they missed subsequent meals, this is not the period of *greatest* risk directly related to the peak action of the 0730 dose. The nurse would monitor for other factors contributing to hypoglycemia at this time rather than the peak effect of this specific insulin dose.
D. 2200 to 0200Regular insulin's duration of action is generally 5 to 7 hours, meaning its effect would have completely worn off by 2200, which is more than 14 hours after administration. Therefore, any hypoglycemia occurring between 2200 and 0200 would not be attributable to the 0730 dose of regular insulin. Hypoglycemia during this late period would likely be due to other factors, such as the action of a long-acting insulin, a missed evening meal, excessive physical activity, or other medications, requiring the nurse to assess for different potential causes.
