Nursing Elites

1. A client with a diagnosis of angina pectoris returns to the nursing unit after experiencing an angioplasty. The nurse reinforces instructions to the client regarding the procedure and home care measures. Which statement by the client indicates an understanding of the instructions?

• A. I am considering cutting my workload.
• B. I need to cut down on cigarette smoking.
• C. I am so relieved that my heart is repaired.
• D. I need to adhere to my dietary restrictions.

Correct answer: D

Rationale: The correct answer is D because adhering to dietary restrictions is crucial in managing heart health post-angioplasty. Choice A focuses on workload, choice B mentions smoking, and choice C reflects relief about heart repair, which are important but do not directly relate to post-angioplasty care instructions.

2. The client is receiving heparin therapy for deep vein thrombosis (DVT). Which lab test should be monitored to evaluate the effectiveness of heparin?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Fibrinogen levels

Correct answer: C

Rationale: Activated partial thromboplastin time (aPTT) is the appropriate lab test to monitor the therapeutic effectiveness of heparin therapy. Heparin affects the intrinsic pathway of the coagulation cascade, and monitoring aPTT helps ensure the client is within the therapeutic range to prevent clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, a different anticoagulant that affects the extrinsic pathway of the coagulation cascade. Fibrinogen levels are not specific to monitoring heparin therapy.

3. When teaching a client with a new prescription for spironolactone, which instruction should the nurse include?

• A. Increase your intake of potassium-rich foods.
• B. Avoid consuming grapefruit juice.
• C. Take the medication with food.
• D. Monitor for signs of hyperkalemia.

Correct answer: D

Rationale: The correct answer is to instruct the client to monitor for signs of hyperkalemia when taking spironolactone since it is a potassium-sparing diuretic. Hyperkalemia is a potential adverse effect due to the medication's mechanism of action. Advising the client to increase potassium-rich foods (Choice A) would be incorrect as it can further elevate potassium levels, which could lead to hyperkalemia. Avoiding grapefruit juice (Choice B) is not directly related to spironolactone use. Though taking the medication with food (Choice C) can help reduce gastrointestinal upset, it is not the most critical instruction when initiating spironolactone therapy.

4. A nurse is assessing a client who has been taking lithium carbonate. Which of the following findings should the nurse report to the provider?

• A. Increased urination
• B. Tremors
• C. Weight gain
• D. Blurred vision

Correct answer: B

Rationale: The correct answer is B: Tremors. Tremors are a sign of lithium toxicity and should be reported immediately. Increased urination is a common side effect of lithium but not an urgent concern requiring immediate reporting. Weight gain is also a common side effect of lithium but does not indicate toxicity. Blurred vision is not typically associated with lithium toxicity; therefore, it is not the priority finding to report.

5. The nurse is caring for a client with a diagnosis of myocardial infarction (MI) and is assisting the client in completing the diet menu. Which beverage does the nurse instruct the client to select from the menu?

• A. Tea
• B. Cola
• C. Coffee
• D. Lemonade

Correct answer: D

Rationale: Lemonade is the correct choice as it is caffeine-free, unlike tea, cola, and coffee, which contain caffeine that can potentially affect the client's heart rhythm. Caffeine can increase heart rate and blood pressure, which may not be advisable for a client with a recent MI. Tea, cola, and coffee should be avoided due to their caffeine content, which can have stimulant effects on the heart and may not be beneficial for a client recovering from a myocardial infarction.
