A client with peripheral vascular disease reports leg pain while walking. What intervention is most effective for the nurse to recommend?

A. Recommend elevating the legs above the heart.

B. Encourage the client to increase walking distance gradually.

C. Encourage the client to avoid sitting or standing for long periods.

D. Instruct the client to use warm compresses for pain relief.

Correct Answer: B
Rationale: The correct answer is to encourage the client to increase walking distance gradually. This intervention is effective because gradual increases in walking distance promote circulation, improve oxygen delivery to tissues, and help reduce leg pain caused by peripheral vascular disease. Elevating the legs above the heart (Choice A) may be beneficial in other conditions like venous insufficiency but not specifically for peripheral vascular disease. Encouraging the client to avoid sitting or standing for long periods (Choice C) can help prevent blood pooling but does not directly address the walking-induced leg pain. Instructing the client to use warm compresses for pain relief (Choice D) may provide temporary relief but does not address the underlying circulation issues associated with peripheral vascular disease.

The nurse is caring for a client with a history of congestive heart failure (CHF) who is receiving digoxin therapy. The client reports seeing halos around lights. Which action should the nurse take?

• A. Assess the client's digoxin level
• B. Increase the client's fluid intake
• C. Check the client's blood pressure
• D. Administer a dose of potassium

Correct Answer: A
Rationale: Seeing halos around lights is a classic symptom of digoxin toxicity. The nurse should assess the client's digoxin level to determine if the dose needs to be adjusted or if the medication should be held. Increasing fluid intake or checking blood pressure would not directly address the symptom of halos around lights. Administering a dose of potassium is not indicated without knowing the digoxin level and could potentially worsen the toxicity.

A client with pneumonia is prescribed antibiotics. What is the most important teaching point for the nurse to provide?

• A. Instruct the client to rest as much as possible.
• B. Encourage increased fluid intake to thin secretions.
• C. Explain the importance of completing the entire course of antibiotics.
• D. Instruct the client to stop taking antibiotics once symptoms subside.

Correct Answer: C
Rationale: The correct answer is C. Antibiotics must be taken for the entire prescribed duration to ensure that the infection is completely eradicated. Stopping antibiotics early, even if symptoms improve, can lead to a recurrence of the infection or antibiotic resistance. Choice A is incorrect because though rest is important, completing the antibiotic course is crucial. Choice B is incorrect as while hydration is beneficial, completing the antibiotics is the priority. Choice D is incorrect as stopping antibiotics prematurely can have negative consequences.

A client with myasthenia gravis (MG) is receiving immunosuppressive therapy. Recent lab tests show decreased serum magnesium. What nursing action is most important?

• A. Observe rhythm on telemetry monitor.
• B. Check for visual difficulties.
• C. Assess for hip and hand joint pain.
• D. Note the most recent hemoglobin level.

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.

At 0600 while admitting a woman for a scheduled repeat cesarean section, the client tells the nurse that she drank a cup of coffee at 0400 because she wanted to avoid getting a headache. Which action should the nurse take first?

• A. Cancel the surgery
• B. Inform the anesthesia care provider
• C. Ask the client if she has had any other liquids
• D. Proceed with routine preparations

Correct Answer: B
Rationale: Drinking liquids before surgery can increase the risk of aspiration during anesthesia. Therefore, the anesthesia care provider must be informed immediately to determine how to proceed, as this could delay or alter the surgical plan. Canceling the surgery without consulting the anesthesia care provider would be premature and could potentially lead to unnecessary actions. Asking the client if she has had any other liquids is important but not the first priority. Proceeding with routine preparations without addressing the potential issue of ingesting liquids before surgery could compromise the client's safety.
