1. The parents of a 4-year-old girl have sought care because their daughter has admitted to chewing and swallowing imported toy figurines that have been determined to be made of lead. Which of the following blood tests should the care team prioritize?

Correct answer: B

Rationale: The correct answer is B: Red blood cell levels and morphology. Lead poisoning primarily affects red blood cells, causing anemia. Therefore, the priority test would be to assess red blood cell levels and morphology. Choice A (White blood cell levels with differential) is incorrect as lead poisoning does not primarily affect white blood cells. Choice C (Urea and creatinine levels) is unrelated to lead poisoning and not a priority in this scenario. Choice D (Liver function panel) is also not the priority as lead poisoning's primary impact is on the red blood cells, not the liver.

2. What are the major mechanisms of spinal cord injuries?

Correct answer: D

Rationale: The correct answer is D. Spinal cord injuries commonly occur due to hyperextension, hyperflexion, and compression. Hyperextension and hyperflexion refer to the excessive bending or stretching of the spinal cord, while compression is the exertion of pressure on the spinal cord. These mechanisms can lead to damage such as contusions, lacerations, and compression of the spinal cord. Choices A, B, and C are incorrect as they do not accurately represent the major mechanisms of spinal cord injuries.

3. A patient is prescribed finasteride (Proscar) for benign prostatic hyperplasia (BPH). What should the nurse include in the patient teaching regarding the expected outcomes of this therapy?

Correct answer: B

Rationale: The correct answer is B. The effects of finasteride in treating BPH may take several weeks or months to become noticeable, so patients should be informed about this expected time frame. Choice A is incorrect because finasteride does not cure BPH but helps manage symptoms. Choice C is incorrect as increased hair growth is a side effect of finasteride, not an expected outcome for BPH treatment. Choice D is also incorrect as decreased libido is a potential side effect of finasteride, not an expected outcome for BPH treatment.

4. Stress-induced cortisol hormone secretion is associated with:

Correct answer: B

Rationale: The correct answer is B: Regulation of the stress response. Cortisol plays a crucial role in regulating the body's response to stress by modulating various physiological processes. Choices A, C, and D are incorrect because stress-induced cortisol hormone secretion is not directly associated with increased growth hormone levels, increased thyroid-stimulating hormone, or depressed adrenal gland function.

5. A patient has been diagnosed with cytomegalovirus (CMV). Which of the following drugs would be ineffective in the treatment of this disease?

Correct answer: A

Rationale: The correct answer is A, Ribavirin (Rebetol). Ribavirin is not effective against CMV. Choice B, Ganciclovir (Cytovene) IV, is a common treatment for CMV as it inhibits viral DNA synthesis. Choice C, Foscarnet (Foscavir) IV, is also used for CMV infections by blocking viral DNA polymerase. Choice D, Valganciclovir hydrochloride (Valcyte), is a prodrug of Ganciclovir and is effective against CMV. Therefore, Ribavirin is the drug that would be ineffective in treating CMV.
