1. In evaluating a 10-year-old child with meningitis suspected of having diabetes insipidus, which finding is indicative of diabetes insipidus?

• A. Decreased urine specific gravity.
• B. Elevated urine glucose.
• C. Decreased serum potassium.
• D. Increased serum sodium.

Correct answer: A

Rationale: Diabetes insipidus is characterized by the kidneys' inability to concentrate urine, leading to decreased urine specific gravity. This results in the excretion of large volumes of dilute urine, causing a decrease in urine specific gravity. Therefore, when evaluating a suspected case of diabetes insipidus, a finding of decreased urine specific gravity is indicative of this condition.

2. Why is morphine administered to a patient with a myocardial infarction (MI)?

• A. To reduce pain.
• B. To decrease anxiety.
• C. To reduce cardiac workload.
• D. To increase respiratory rate.

Correct answer: C

Rationale: Morphine is administered to a patient with a myocardial infarction (MI) primarily to reduce cardiac workload. By reducing preload and afterload, morphine helps improve oxygenation to the heart muscle. This decrease in workload on the heart can alleviate symptoms and reduce strain on the heart muscle during an MI. Choices A and B are incorrect because the primary goal of administering morphine in this context is not pain relief or anxiety reduction. Choice D is incorrect as morphine does not aim to increase respiratory rate but rather to address the cardiac workload.

3. A client with liver failure is at an increased risk of bleeding due to the inability to synthesize prothrombin in the liver. What factor most likely contributes to this loss of function?

• A. Alterations in glucose metabolism
• B. Retention of bile salts
• C. Inadequate production of albumin by hepatocytes
• D. Inability of the liver to use vitamin K

Correct answer: D

Rationale: The correct answer is D. The liver's inability to use vitamin K is the most likely factor contributing to the loss of prothrombin synthesis in liver failure. Vitamin K is essential for the synthesis of prothrombin, a crucial clotting factor. In liver failure, impaired utilization of vitamin K leads to decreased production of prothrombin, increasing the risk of bleeding in affected individuals.

4. The healthcare provider is assessing a client with Cushing's syndrome. Which clinical manifestation should the healthcare provider expect to find?

• A. Hyperpigmentation of the skin.
• B. Hypotension.
• C. Moon face and buffalo hump.
• D. Weight loss.

Correct answer: C

Rationale: The correct answer is C: Moon face and buffalo hump. In Cushing's syndrome, excess production of corticosteroids leads to redistribution of fat, particularly in the face (moon face) and between the shoulders (buffalo hump). Hyperpigmentation of the skin is actually associated with Addison's disease, not Cushing's syndrome (choice A). Hypotension is not a typical finding in Cushing's syndrome; instead, hypertension is more commonly seen due to the effects of excess cortisol (choice B). Weight gain, rather than weight loss, is a common symptom of Cushing's syndrome due to the metabolic disturbances caused by excess cortisol (choice D).

5. When assessing a client with suspected meningitis, which finding is indicative of meningeal irritation?

• A. Brudzinski's sign
• B. Positive Babinski reflex
• C. Kernig's sign
• D. Both A and C

Correct answer: D

Rationale: Both Brudzinski's sign and Kernig's sign are classic signs of meningeal irritation, commonly associated with meningitis. Brudzinski's sign is positive when flexing the neck causes involuntary flexion of the hips and knees due to irritation of the meninges. Kernig's sign is positive when there is pain and resistance with knee extension after hip flexion, indicating meningeal irritation or inflammation. The Babinski reflex, mentioned in choice B, is a test used to assess upper motor neuron damage and is not specific to meningitis. Therefore, choices A and C are the correct options as they are indicative of meningeal irritation in a suspected case of meningitis.
