Nursing Elites

1. A 35-year-old man presents with fatigue, weight loss, and hyperpigmentation of the skin. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?

• A. Cushing's syndrome
• B. Addison's disease
• C. Hypothyroidism
• D. Pheochromocytoma

Correct answer: B

Rationale: The clinical presentation of a 35-year-old man with fatigue, weight loss, hyperpigmentation of the skin, hyponatremia, hyperkalemia, and low cortisol levels is classic for Addison's disease. These findings are consistent with primary adrenal insufficiency, where the adrenal glands fail to produce adequate cortisol. In Addison's disease, the adrenal cortex is damaged, leading to decreased cortisol production and elevated levels of ACTH. This results in symptoms such as fatigue, weight loss, and hyperpigmentation due to increased ACTH production stimulating melanocytes. Hyponatremia and hyperkalemia are common electrolyte abnormalities seen in Addison's disease due to aldosterone deficiency. Therefore, the correct diagnosis in this case is Addison's disease.

2. While assessing a client with preeclampsia who is receiving magnesium sulfate, the nurse notes her deep tendon reflexes are 1+, respiratory rate is 12 breaths/minute, urinary output is 90 ml in 4 hours, and magnesium sulfate level is 9 mg/dl. What intervention should the nurse implement based on these findings?

• A. Continue the magnesium sulfate infusion as prescribed.
• B. Decrease the magnesium sulfate infusion by one-half.
• C. Stop the magnesium sulfate infusion immediately.
• D. Administer calcium gluconate immediately.

Correct answer: C

Rationale: The nurse should stop the magnesium sulfate infusion immediately in a client with preeclampsia exhibiting diminished reflexes, respiratory depression, and low urinary output, which indicate magnesium sulfate toxicity. This action is crucial to prevent further complications and adverse effects on the client.

3. A client with chronic kidney disease (CKD) has an arteriovenous (AV) fistula for hemodialysis. Which finding should the nurse report to the healthcare provider immediately?

• A. No bruit or thrill over the AV fistula.
• B. Redness at the site of the AV fistula.
• C. Client's complaint of pain at the AV fistula site.
• D. Swelling of the hand on the side of the AV fistula.

Correct answer: A

Rationale: In a client with a chronic kidney disease who has an arteriovenous (AV) fistula for hemodialysis, the absence of a bruit (a humming sound) or thrill (vibratory sensation) over the AV fistula indicates a potential occlusion. This finding suggests inadequate blood flow through the AV fistula, which is a critical issue requiring immediate intervention to prevent complications such as thrombosis or clot formation. Reporting this absence of bruit or thrill promptly to the healthcare provider is essential to ensure timely assessment and management to maintain vascular access for hemodialysis.

4. A client's health history is suggestive of inflammatory bowel disease. Which of the following would suggest Crohn disease, rather than ulcerative colitis, as the cause of the client's signs and symptoms?

• A. A pattern of distinct exacerbations and remissions
• B. Severe diarrhea
• C. An absence of blood in stool
• D. Involvement of the rectal mucosa

Correct answer: C

Rationale: In the context of inflammatory bowel disease, the absence of blood in stool is more indicative of Crohn disease. Crohn disease typically presents with non-bloody stools, while ulcerative colitis often involves bloody stools due to continuous mucosal inflammation confined to the colon and rectum.

5. The healthcare professional is caring for a client with heart failure who is receiving digoxin (Lanoxin). Which assessment finding requires immediate intervention?

• A. Heart rate of 58 beats per minute.
• B. Nausea and vomiting.
• C. Blood pressure of 130/80 mm Hg.
• D. Shortness of breath.

Correct answer: B

Rationale: The correct answer is B. Nausea and vomiting are common signs of digoxin toxicity, which can lead to serious complications like dysrhythmias. Prompt intervention is crucial to prevent further harm to the client. Choice A, a heart rate of 58 beats per minute, although slightly lower than normal, may be appropriate for a client on digoxin. Choice C, a blood pressure of 130/80 mm Hg, is within normal limits and does not indicate an immediate need for intervention. Choice D, shortness of breath, is a common symptom in heart failure and requires monitoring but is not as indicative of digoxin toxicity as nausea and vomiting.
