1. Which statement best conveys an aspect of the role of cerebrospinal fluid (CSF)?

• A. CSF provides immune protection to the brain and spinal cord by serving as a physical barrier.
• B. CSF cushions the brain and spinal cord, protecting them from injury.
• C. CSF plays a limited role in the exchange of nutrients and waste products between the blood and brain.
• D. CSF functions primarily as a medium for the transmission of nerve impulses.

Correct answer: B

Rationale: The correct answer is B. Cerebrospinal fluid primarily cushions the brain and spinal cord, protecting them from injury. Choice A is incorrect because while CSF contributes to the brain's immune environment, its main role is not providing immune protection as a physical barrier. Choice C is incorrect because CSF has a significant role in the exchange of nutrients and waste products, rather than a limited one. Choice D is incorrect as CSF is not primarily a medium for nerve impulse transmission, but rather serves as a protective and supportive fluid.

2. The parents of a 3-year-old boy have brought him to a pediatrician for assessment of the boy's late ambulation and frequent falls. Subsequent muscle biopsy has confirmed a diagnosis of Duchenne muscular dystrophy. Which teaching point should the physician include when explaining the child's diagnosis to his parents?

• A. Your child may develop breathing difficulties as the disease progresses.
• B. Your child is likely to benefit from physical therapy and exercise.
• C. This condition can be cured with early intervention and treatment.
• D. The disease is caused by inflammation in the muscles, which leads to weakness.

Correct answer: A

Rationale: The correct teaching point that the physician should include when explaining Duchenne muscular dystrophy to the parents is that 'Your child may develop breathing difficulties as the disease progresses.' Duchenne muscular dystrophy is a progressive condition that affects muscle strength, including respiratory muscles, leading to breathing difficulties as the disease advances. Choice B is incorrect because while physical therapy and exercise can help maintain muscle function and mobility, they do not cure the condition. Choice C is incorrect because Duchenne muscular dystrophy is a genetic disorder with no known cure. Choice D is incorrect as Duchenne muscular dystrophy is primarily characterized by a lack of dystrophin protein due to genetic mutations, not inflammation in the muscles.

3. When assessing for potential signs and symptoms of cryptococcosis in a patient with HIV being treated with Amphotericin B, the nurse should prioritize what assessment?

• A. Neurological assessment
• B. Functional assessment
• C. Nutritional assessment
• D. Cardiac assessment

Correct answer: A

Rationale: In a patient with cryptococcosis and HIV, neurological assessment should be prioritized because cryptococcosis commonly affects the central nervous system, leading to symptoms such as headache, confusion, and altered mental status. This assessment is crucial in monitoring for any neurological complications and guiding appropriate interventions. Functional assessment focuses on the patient's ability to perform activities of daily living and is not directly associated with cryptococcosis. Nutritional assessment is important for overall health but is not the priority when assessing for cryptococcosis. Cardiac assessment is not a priority in cryptococcosis as the primary manifestations are related to the central nervous system.

4. A patient with systemic candidiasis has been prescribed flucytosine. The nurse should be aware of the need to administer this drug with which of the following?

• A. Vitamin D and calcium supplements
• B. Fluconazole (Diflucan)
• C. Amphotericin B
• D. Penicillin G

Correct answer: C

Rationale: The correct answer is C: Amphotericin B. When treating systemic candidiasis, Amphotericin B is the drug of choice, not flucytosine. Amphotericin B is an antifungal medication used to treat severe fungal infections like systemic candidiasis. Choices A, B, and D are incorrect because vitamin D and calcium supplements, fluconazole, and penicillin G are not the drugs of choice for treating systemic candidiasis.

5. A patient is prescribed estradiol (Estrace) for hormone replacement therapy. What should the nurse monitor during this therapy?

• A. Blood pressure
• B. Blood glucose levels
• C. Liver function tests
• D. Kidney function tests

Correct answer: C

Rationale: During estradiol therapy, the nurse should monitor liver function tests. Estradiol can potentially impact liver function, making it essential to assess for any signs of liver dysfunction. Monitoring blood pressure (Choice A) is not directly related to estradiol therapy. While blood glucose levels (Choice B) should be monitored in patients taking certain medications like corticosteroids or antipsychotics, it is not typically necessary for patients on estradiol therapy. Kidney function tests (Choice D) are not the priority for monitoring during estradiol therapy, as the liver is more commonly affected.
