CAT Exam Practice

Correct Answer: C

Rationale: Continuing outpatient treatment is crucial for managing anorexia nervosa and preventing future complications. Reinforcing the need to continue outpatient treatment ensures ongoing support, monitoring, and therapy for the client's anorexia nervosa. Describing the importance of maintaining stable blood glucose levels (Choice A) is relevant but does not address the underlying eating disorder directly. Encouraging a balanced and nutritious diet (Choice B) is important; however, specific dietary recommendations should be tailored to the individual's condition by healthcare providers. Educating on the risks of untreated anorexia nervosa (Choice D) is informative but does not provide a direct actionable step for the client's immediate discharge plan, unlike the importance of continuing outpatient treatment.

Correct Answer: B

Rationale: To prepare 25 mEq of potassium chloride for the infusion, the nurse should add 5 ml of the 10 mEq/5 ml solution. This concentration provides the required amount of potassium chloride without exceeding the needed volume. Choice A would result in 12.5 mEq, which exceeds the prescribed amount. Choices C and D are incorrect as they do not align with the correct calculation based on the vial concentration.

Correct Answer: C

Rationale: Continuously monitoring blood pressure is crucial in this case because nitroglycerin can cause hypotension as a side effect. Monitoring blood pressure allows the nurse to assess the client's response to the medication and detect any signs of hypotension promptly. This intervention is essential to ensure the effectiveness of nitroglycerin therapy and prevent potential complications. Administering the infusion via an infusion pump is important for accurate dosing but not the most critical at this moment. Obtaining the current serum potassium level is important but not the most immediate concern when the client is experiencing active chest pain. Teaching guided imagery may be beneficial for pain management, but in this scenario, monitoring blood pressure takes precedence due to the potential side effects of nitroglycerin.

Correct Answer: A

Rationale: Monitoring cardiac activity is crucial in this scenario because hyperkalemia can lead to serious cardiac dysrhythmias, which can be life-threatening. Regular monitoring of the client's cardiac activity via telemetry allows for early detection of any potential cardiac complications. Maintaining venous access with a normal saline infusion is important for hydration but does not address the immediate risk of cardiac dysrhythmias posed by hyperkalemia. Assessing glucose levels is essential in diabetes management but is not the priority when dealing with hyperkalemia-induced cardiac risks. Evaluating hourly urine output for the return of normal renal function is important in ARF but is not as urgent as monitoring the client's cardiac activity in the context of hyperkalemia.
