- A. Hyperlipidemia
- B. Diabetes mellitus

The nurse is caring for a client who has adrenal insufficiency (Addison's disease). Which of the following interventions would be a priority?
- A. Administer prescribed hydrocortisone
- B. Offer salty snacks and water
- C. Assess skin integrity
- D. Encourage frequent rest periods
Correct Answer: A
Rationale: Adrenal insufficiency causes cortisol deficiency, leading to hypotension and weakness. Administering hydrocortisone is critical to replace cortisol and stabilize the client. Salty snacks, skin checks, and rest are supportive but not the priority.
The nurse is assessing a client with a myxedema coma. Which of the following would be an expected finding?
- A. Glucose 59 mg/dL (3.28 mmol/L) [70-110 mg/d, 4.0-6.0 mmol/L]
- B. Sodium 155 mEq/L (mmol/L) [135-145 mEq/L, mmol/L]
- C. Serum pH 7.49 [7.35-7.45]
Correct Answer: A
Rationale: Myxedema coma, a severe hypothyroid state, can cause hypoglycemia due to reduced metabolism. Hypernatremia and alkalosis are not typical; hyponatremia and acidosis are more common.
The nurse is reviewing newly prescribed medications for assigned clients. Which of the following prescribed medications should the nurse question?
- A. Furosemide for a client with hyperparathyroidism
- B. Methimazole for a client with hyperthyroidism
- C. Hydrocortisone for a client with diabetes insipidus
- D. Prazosin for a client with pheochromocytoma
Correct Answer: C
Rationale: Hydrocortisone is inappropriate for diabetes insipidus, which requires desmopressin to manage water reabsorption. Furosemide may be used in hyperparathyroidism, methimazole treats hyperthyroidism, and prazosin manages hypertension in pheochromocytoma.
The nurse is caring for a client who recently had a dosage increase of prescribed levothyroxine. Which of the assessments following the increase is a priority?
- A. Weight
- B. Heart rate
- C. Activity status
- D. Oral temperature
Correct Answer: B
Rationale: Levothyroxine increases metabolism, and a dosage increase can cause hyperthyroidism symptoms, including tachycardia. Monitoring heart rate is a priority to detect adverse effects like arrhythmias. Weight, activity status, and temperature are relevant but less urgent.
The nurse is caring for a client who is receiving newly prescribed prednisone. Which of the following medications should the client avoid while receiving this medication?
- A. valsartan
- B. naproxen
- C. omeprazole
- D. acetaminophen
Correct Answer: B
Rationale: Naproxen, an NSAID, should be avoided with prednisone due to increased risk of gastrointestinal bleeding and ulceration. Valsartan, omeprazole, and acetaminophen are generally safe with prednisone, though monitoring is needed.
