HESI 799 RN Exit Exam Capstone

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: Magnesium plays a crucial role in maintaining normal cardiac rhythms, particularly in patients with cardiac conditions. Abnormal levels can lead to arrhythmias, which is why continuous monitoring of the heart's electrical activity is important. Magnesium's effect on neuromuscular and cardiac function makes it essential to monitor its levels, and any discrepancies can impact treatment decisions. Checking for visual difficulties (choice B) may be important in MG but is not the priority in the context of decreased serum magnesium. Assessing for hip and hand joint pain (choice C) is not directly related to the issue of decreased serum magnesium. Noting the most recent hemoglobin level (choice D) is not the priority in this situation compared to monitoring the cardiac rhythm due to low magnesium levels.

Correct Answer: B

Rationale: The correct initial action for a client with anxiety disorder experiencing increased anxiety prior to vaginal delivery is to encourage the client to express her feelings and provide emotional support. Emotional support is crucial in reducing anxiety during childbirth. Initiating breathing techniques or administering medications should come after emotional support has been provided. Increasing sedative doses may not address the underlying emotional needs of the client and can have potential risks.

Correct Answer: B

Rationale: An adolescent expressing 'life without purpose' after taking duloxetine (Cymbalta) may be indicating suicidal ideation, which requires immediate attention. The initial period of antidepressant treatment can increase the risk of suicidal thoughts, especially in younger populations. Increased appetite (Choice A) is a common side effect of duloxetine and may not require immediate follow-up. Mood swings (Choice C) and insomnia (Choice D) are also possible side effects of the medication but are not as urgent as addressing suicidal ideation.

Correct Answer: C

Rationale: The best intervention for a client with dysphagia experiencing difficulty swallowing medications is to consult with the healthcare provider about switching to liquid medications. Liquid medications are often easier to swallow and can reduce the risk of choking and aspiration in clients with dysphagia. Crushing medications can alter their effectiveness, encouraging the client to drink water may not be sufficient, and offering soft foods is not directly related to improving medication swallowing.
