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. Because the census is currently low in the Obstetrics (OB) unit, one of the nurses is sent to work on a medical-surgical unit for the day, or until the OB unit becomes busy. Which client assessment is best for the charge nurse to assign to the OB nurse?

• A. An adult who had a colon resection yesterday and has an IV.
• B. An older adult who has a fever of unknown origin.
• C. A woman who had an acute brain attack (stroke, CVA) 6 hours ago.
• D. A teenager with a femoral fracture who is in traction.

Correct answer: A

Rationale: The OB nurse is most experienced in postoperative care, making the client who had a recent colon resection the most suitable assignment. This client would require care that aligns closely with the expertise and skills of the OB nurse, ensuring optimal patient outcomes and effective utilization of nursing resources.

3. A client with chronic renal failure is scheduled to receive epoetin alfa (Epogen). Which laboratory result should the nurse review before administering the medication?

• A. Blood urea nitrogen (BUN)
• B. Creatinine clearance
• C. Hemoglobin level
• D. Serum potassium

Correct answer: C

Rationale: The correct answer is to review the hemoglobin level before administering epoetin alfa (Epogen) to assess its effectiveness in stimulating red blood cell production. Hemoglobin level is a crucial indicator to monitor in clients with chronic renal failure receiving this medication. Choice A (Blood urea nitrogen) and Choice B (Creatinine clearance) are commonly monitored in renal failure but are not specifically relevant to assessing the effectiveness of epoetin alfa. Choice D (Serum potassium) is important to monitor due to potential imbalances in renal failure, but it is not directly related to evaluating the effectiveness of epoetin alfa.

4. A client with hypertension is receiving dietary education from a nurse. Which recommendation should the nurse include?

• A. Increase your intake of saturated fats.
• B. Limit your sodium intake to less than 2 grams per day.
• C. Avoid foods high in potassium.
• D. Consume at least three alcoholic beverages daily.

Correct answer: B

Rationale: The correct recommendation for a client with hypertension is to limit sodium intake to less than 2 grams per day. High sodium intake can worsen hypertension by increasing blood pressure. Choices A, C, and D are incorrect. Increasing saturated fats (Choice A) can be detrimental to heart health and exacerbate hypertension. Avoiding foods high in potassium (Choice C) is not recommended as potassium-rich foods can actually be beneficial for managing blood pressure. Consuming three alcoholic beverages daily (Choice D) can also have a negative impact on blood pressure and overall health.

5. The healthcare provider prescribes 15 mg/kg of Streptomycin for an infant weighing 4 pounds. The drug is diluted in 25 ml of D5W to run over 8 hours. How much Streptomycin will the infant receive?

• A. 9 mg
• B. 18 mg
• C. 27 mg
• D. 36 mg

Correct answer: A

Rationale: To calculate the dosage, first, convert the weight from pounds to kg (4 lbs / 2.2 ≈ 1.82 kg). Then, multiply by the prescribed mg/kg (15 mg/kg * 1.82 kg ≈ 27.3 mg). However, since the question asks for the closest correct option, the infant will receive approximately 9 mg.
