Nursing Elites

1. The LPN/LVN is assisting in caring for a client in the telemetry unit and is monitoring the client for cardiac changes indicative of hypokalemia. Which occurrence noted on the cardiac monitor indicates the presence of hypokalemia?

• A. Tall, peaked T waves
• B. ST-segment depression
• C. Prolonged P-R interval
• D. Widening of the QRS complex

Correct answer: B

Rationale: ST-segment depression can indicate hypokalemia, affecting the heart's electrical conduction. Hypokalemia leads to alterations in the repolarization phase of the cardiac action potential, resulting in ST-segment depression on the ECG. Tall, peaked T waves are indicative of hyperkalemia, not hypokalemia. A prolonged P-R interval is more commonly associated with first-degree heart block. Widening of the QRS complex is typically seen in conditions like bundle branch blocks or ventricular tachycardia, not specifically in hypokalemia.

2. A client with a diagnosis of hypertension is prescribed atenolol (Tenormin). The nurse should monitor the client for which common side effect of this medication?

• A. Tachycardia
• B. Dry mouth
• C. Hypotension
• D. Increased appetite

Correct answer: C

Rationale: Corrected Rationale: Atenolol is a beta-blocker that commonly causes hypotension by lowering blood pressure. Therefore, monitoring for hypotension is crucial to prevent potential complications in the client receiving this medication. The other options are incorrect: A) Tachycardia is not a common side effect of atenolol as it typically reduces heart rate, B) Dry mouth is not a typical side effect of atenolol, and D) Increased appetite is not commonly associated with atenolol use.

3. A client with a new prescription for simvastatin is receiving teaching from a healthcare provider. Which of the following statements by the client indicates an understanding of the teaching?

• A. 'I should take this medication in the evening.'
• B. 'I should avoid drinking grapefruit juice.'
• C. 'I should expect my urine to be red-orange while taking this medication.'
• D. 'I will need to take this medication for the rest of my life.'

Correct answer: A

Rationale: The correct answer is A. Taking simvastatin in the evening is recommended because cholesterol synthesis increases at night. This timing maximizes the effectiveness of the medication in lowering cholesterol levels. Choice B is incorrect because grapefruit juice should be avoided with certain statins, but simvastatin is not significantly affected by grapefruit juice. Choice C is incorrect as red-orange urine is not an expected side effect of simvastatin. Choice D is incorrect because simvastatin is typically prescribed for managing cholesterol levels and may not need to be taken for the rest of the client's life.

4. The healthcare professional is reinforcing teaching for a client with peripheral artery disease (PAD). Which statement by the client indicates a need for further teaching?

• A. I will keep my legs elevated on pillows while resting.
• B. I will avoid crossing my legs when sitting.
• C. I will wear loose-fitting, comfortable shoes.
• D. I will avoid exposure to cold temperatures.

Correct answer: A

Rationale: The correct answer is A. Elevating the legs can decrease blood flow in clients with PAD, worsening symptoms. Therefore, advising the client to keep the legs elevated on pillows while resting is incorrect and can exacerbate the condition. Choice B is correct as avoiding crossing legs helps prevent circulation restriction. Choice C is correct as wearing loose-fitting shoes promotes circulation. Choice D is correct as avoiding exposure to cold temperatures helps prevent vasoconstriction, which can worsen PAD symptoms.

5. The client is being ambulated due to activity intolerance caused by bacterial endocarditis. How can the nurse determine that the client is best tolerating ambulation?

• A. Mild dyspnea after walking 10 feet
• B. Minimal chest pain rated 1 on a 1-to-10 pain scale
• C. Pulse rate that increases from 68 to 94 beats per minute
• D. Blood pressure that increases from 114/82 to 118/86 mm Hg

Correct answer: D

Rationale: A slight increase in blood pressure without significant symptoms indicates that the client is tolerating the activity. In this scenario, a mild increase in blood pressure without other symptoms is a positive sign of tolerance to ambulation despite the underlying condition of bacterial endocarditis. Choices A, B, and C are not the best indicators of tolerance to ambulation in this case. Mild dyspnea after walking a short distance, minimal chest pain, and an increase in pulse rate are common signs that the activity might not be well-tolerated by the client with a history of bacterial endocarditis.
