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 hypertensive client who has been taking metoprolol (Lopressor) has been prescribed to decrease the dose of the medication. The client asks the nurse why this must be done over a period of 1 to 2 weeks. In formulating a response, the nurse incorporates the understanding that abrupt withdrawal could affect the client in which way?

• A. Result in hypoglycemia
• B. Give the client insomnia
• C. Precipitate rebound hypertension
• D. Cause enhanced side effects of other prescribed medications

Correct answer: C

Rationale: Abruptly stopping metoprolol can lead to rebound hypertension, causing a sudden increase in blood pressure due to the sudden withdrawal of the medication. Gradually tapering the dose helps the body adjust and reduces the risk of this adverse effect. Choices A, B, and D are incorrect. Stopping metoprolol suddenly is not known to result in hypoglycemia, insomnia, or enhanced side effects of other medications.

3. A nurse is assessing a client who has been taking levothyroxine for hypothyroidism. Which of the following findings should the nurse report to the provider?

• A. Weight loss
• B. Insomnia
• C. Heat intolerance
• D. Dry skin

Correct answer: C

Rationale: The correct answer is C: Heat intolerance. Heat intolerance is a sign of levothyroxine toxicity and requires immediate attention. Weight loss may actually be an expected outcome of levothyroxine therapy as it can help regulate metabolism in hypothyroidism. Insomnia can occur as a side effect of levothyroxine but is not as concerning as heat intolerance. Dry skin is a common symptom of hypothyroidism and may improve with levothyroxine therapy, so it is not a priority finding to report to the provider.

4. A client who has been taking prednisone is being assessed by a nurse. Which of the following findings should the nurse report to the provider?

• A. Weight gain
• B. Hyperglycemia
• C. Dry mouth
• D. Increased appetite

Correct answer: B

Rationale: Hyperglycemia is a significant finding in a client taking prednisone as it indicates the medication's impact on glucose metabolism. Prednisone can lead to increased blood sugar levels, which can be detrimental, especially in clients with diabetes or predisposition to hyperglycemia. Reporting hyperglycemia promptly to the healthcare provider is crucial for further evaluation and management to prevent complications. Choices A, C, and D are common side effects of prednisone but are not as concerning as hyperglycemia, which requires immediate attention to avoid potential adverse effects.

5. A client with a diagnosis of angina pectoris is prescribed nitroglycerin tablets. How should the nurse instruct the client to take the medication?

• A. Swallow the tablet whole with water
• B. Place the tablet under the tongue and let it dissolve
• C. Chew the tablet and then swallow
• D. Place the tablet between the cheek and gum

Correct answer: B

Rationale: Nitroglycerin is most effective when administered sublingually (under the tongue) as it is rapidly absorbed into the bloodstream. Placing the tablet under the tongue allows for quick absorption and faster relief of angina symptoms. Chewing the tablet, swallowing it, or placing it between the cheek and gum would not provide the same rapid onset of action needed during an angina episode. Therefore, the correct instruction for the client is to place the nitroglycerin tablet under the tongue and let it dissolve for optimal effectiveness.
