Nursing Elites

1. A 60-year-old man presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The presentation of a 60-year-old man with fatigue, polyuria, polydipsia, hyperglycemia, and ketonuria strongly suggests type 1 diabetes mellitus. Type 1 diabetes typically presents with acute symptoms due to absolute insulin deficiency, leading to hyperglycemia and ketonuria. Conversely, type 2 diabetes often presents more insidiously and is associated with relative insulin deficiency and insulin resistance. Diabetes insipidus, a condition characterized by excessive thirst and excretion of large amounts of dilute urine, is due to problems with antidiuretic hormone (ADH) and is not associated with hyperglycemia or ketonuria. Hyperthyroidism, while also presenting with symptoms like fatigue, does not typically manifest with hyperglycemia or ketonuria. Therefore, based on the clinical presentation and laboratory findings, the most likely diagnosis in this case is type 1 diabetes mellitus.

2. When should surgical correction of hypospadias typically occur for a newborn infant as advised by the nurse?

• A. Repair should be done within one month to prevent bladder infections.
• B. Repairs should typically be done before the child is potty-trained.
• C. Delaying the repair until school age reduces castration fears.
• D. To form a proper urethra repair, it should be done after sexual maturity.

Correct answer: B

Rationale: Surgical repair of hypospadias is recommended to be performed before the child is potty-trained to prevent complications. Early correction helps in achieving better outcomes and reduces the risk of issues related to urination and development of the genitalia.

3. A 70-year-old woman presents with fatigue, anorexia, and weight loss. She has noticed darkening of her skin, particularly in sun-exposed areas. 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 combination of symptoms such as fatigue, anorexia, weight loss, hyperpigmentation of the skin, along with hyponatremia, hyperkalemia, and low cortisol levels, points towards Addison's disease. This condition is characterized by adrenal insufficiency, leading to a deficiency in cortisol and aldosterone production.

4. A client with peptic ulcer disease is prescribed omeprazole (Prilosec). Which instruction should the nurse include in the client's teaching plan?

• A. Take the medication with food.
• B. Take the medication at bedtime.
• C. Take the medication on an empty stomach.
• D. Take the medication as needed for pain relief.

Correct answer: C

Rationale: The correct instruction for a client prescribed omeprazole (Prilosec) is to take the medication on an empty stomach. This is important for optimal absorption and effectiveness of the medication in treating peptic ulcer disease. Choice A ('Take the medication with food') is incorrect because omeprazole should be taken on an empty stomach. Choice B ('Take the medication at bedtime') is incorrect as it does not align with the optimal timing for omeprazole administration. Choice D ('Take the medication as needed for pain relief') is incorrect because omeprazole is not typically used for immediate pain relief but rather for long-term management of peptic ulcer disease.

5. A 60-year-old woman presents with pruritus, jaundice, and xanthomas. Laboratory tests reveal elevated cholesterol and alkaline phosphatase levels. What is the most likely diagnosis?

• A. Primary biliary cirrhosis
• B. Primary sclerosing cholangitis
• C. Gallstones
• D. Pancreatic cancer

Correct answer: A

Rationale: The combination of pruritus, jaundice, and xanthomas, along with elevated cholesterol and alkaline phosphatase levels, is classic for primary biliary cirrhosis. Pruritus is often the initial symptom, followed by jaundice due to cholestasis. Xanthomas, elevated cholesterol, and alkaline phosphatase levels are also common findings in primary biliary cirrhosis. Primary sclerosing cholangitis and pancreatic cancer may present with similar symptoms but are less likely in this clinical context.
