Nursing Elites

1. 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.

2. A mother reports that she has been applying triple antibiotic ointment for her son's athlete's foot for two days with no improvement. What should the nurse instruct?

• A. Continue using the ointment and keep the area clean.
• B. Stop using the ointment and encourage the feet to be dried completely.
• C. Apply a different antifungal medication instead.
• D. Reapply the ointment twice a day for a longer period.

Correct answer: B

Rationale: Antibiotic ointment is ineffective against athlete's foot, which is a fungal infection. The nurse should instruct the mother to stop using the ointment and ensure the feet are dried properly, as moisture exacerbates fungal infections. Applying a different antifungal medication is a valid option, but addressing the moisture issue by drying the feet completely is the immediate priority. Continuing to use the antibiotic ointment or reapplying it for a longer period will not treat the fungal infection effectively.

3. A client is experiencing angina at rest. Which statement indicates a good understanding of the care required?

• A. I will notify the nurse if my chest pain is not relieved in 30 minutes.
• B. I will use nitroglycerin as needed, every 5 minutes, up to 3 doses.
• C. I will avoid physical activity until the pain subsides completely.
• D. I will take nitroglycerin 30 minutes before any physical activity.

Correct answer: B

Rationale: The correct answer is B. Using nitroglycerin as needed, every 5 minutes, up to 3 doses, is the appropriate management for angina at rest. This helps dilate blood vessels, improving blood flow to the heart. Choice A is incorrect because chest pain that persists at rest should be addressed immediately, not waiting for 30 minutes. Choice C is incorrect as avoiding physical activity is not a recommended approach during an angina episode. Choice D is incorrect because nitroglycerin should be used during chest pain episodes, not as a preventive measure before physical activity.

4. During an assessment of a client with congestive heart failure, the nurse is most likely to hear which of the following upon auscultation of the heart?

• A. S3 ventricular gallop
• B. Apical click
• C. Systolic murmur
• D. Split S2

Correct answer: A

Rationale: Correct Answer: An S3 ventricular gallop is an abnormal heart sound commonly heard in clients with congestive heart failure. This sound is indicative of fluid overload or volume expansion in the ventricles, which is often present in heart failure. <br> Incorrect Answers: <br> B: An apical click is not typically associated with congestive heart failure. <br> C: A systolic murmur may be heard in various cardiac conditions but is not specific to congestive heart failure. <br> D: A split S2 refers to a normal heart sound caused by the closure of the aortic and pulmonic valves at slightly different times during inspiration, not directly related to congestive heart failure.

5. A client recently started on warfarin therapy. What laboratory value is most important to monitor for this client?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Creatinine level
• D. Blood urea nitrogen (BUN)

Correct answer: B

Rationale: Prothrombin time (PT) is the most important laboratory value to monitor for clients on warfarin therapy. PT helps determine how long it takes blood to clot and ensures the warfarin dose is within the therapeutic range to prevent either excessive bleeding or clotting. Monitoring platelet count is important for assessing the risk of bleeding, but PT is more specific to warfarin therapy. Creatinine level and BUN are indicators of kidney function and are not directly related to warfarin therapy.
