A client with multiple sclerosis is receiving intravenous methylprednisolone. What is the nurse's priority action?

Correct Answer: B

Rationale: When a client with multiple sclerosis is receiving intravenous methylprednisolone, the nurse's priority action is to monitor for signs of infection. Corticosteroids like methylprednisolone can suppress the immune system, increasing the risk of infection. Monitoring for signs of infection allows for early detection and prompt intervention. Monitoring blood glucose levels may be important in clients receiving corticosteroids for prolonged periods, but it is not the priority in this case. Encouraging increased oral fluid intake is generally beneficial but not the priority over monitoring for infection. Checking the client's temperature is important but not the priority action compared to monitoring for signs of infection.

Correct Answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen via nasal cannula. Oxygen therapy is the priority intervention for a client with COPD experiencing increasing shortness of breath. It helps improve oxygenation and relieve respiratory distress. Choice B is not the priority as oxygenation needs to be addressed first. Choice C, chest physiotherapy, may be beneficial but is not the immediate priority in this situation. Choice D, encouraging the client to cough and deep breathe, is not the priority intervention when oxygenation is compromised.

Correct Answer: B

Rationale: The correct answer is to redirect the client to a quiet activity. This intervention helps reduce agitation and aggression in clients with Alzheimer's disease by providing a distraction and promoting a calming environment. Reassuring the client and providing emotional support (Choice A) can be beneficial but is not the priority in this situation. Administering a PRN dose of lorazepam (Choice C) should not be the first intervention due to the risk of adverse effects and should only be considered if other non-pharmacological interventions are ineffective. Applying restraints (Choice D) should be avoided unless absolutely necessary for the client's safety as it can lead to further distress and is not the initial priority intervention.

Correct Answer: D

Rationale: Dark, tarry stools indicate the presence of digested blood in the gastrointestinal tract, signifying a higher gastrointestinal bleed. This finding requires immediate intervention due to the potential severity of the bleed. Bright red blood in the vomit may indicate active bleeding but is not as concerning as digested blood. Elevated blood pressure and heart rate are common responses to bleeding but do not provide direct evidence of the source or severity of the bleed. Coffee ground emesis is indicative of partially digested blood and is a concern but not as urgent as dark, tarry stools.
