An older adult patient has just sheared the skin on her elbow while attempting to boost herself up in bed, an event that has precipitated acute inflammation in the region surrounding the wound. Which of the following events will occur during the vascular stage of the patient's inflammation?

Correct Answer: A

Rationale: During the vascular stage of inflammation, there is an outpouring of exudate into the interstitial spaces, leading to swelling and edema. Choice B, chemotaxis, occurs during the cellular stage of inflammation, where leukocytes move to the site of injury in response to chemical signals. Choice C, accumulation of leukocytes along the epithelium, is not a typical event during the vascular stage. Phagocytosis of cellular debris, as in choice D, mainly occurs during the resolution stage of inflammation.

Correct Answer: B

Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels and effectiveness. This is crucial for the drug to work optimally. Choice A is incorrect because medroxyprogesterone acetate does not necessarily need to be taken with food to prevent nausea. Choice C is not directly related to the medication's administration and is not a common teaching point for this drug. Choice D is incorrect as discontinuing the medication abruptly can lead to adverse effects and is not recommended without consulting a healthcare provider.

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. It is important for the nurse to educate the patient about this expected time frame to manage expectations. Choice A is incorrect because finasteride does not cure BPH but helps in managing symptoms. Choice C is incorrect as one of the side effects of finasteride is decreased hair growth. Choice D is incorrect as finasteride may cause a decrease in libido as a side effect.

Correct Answer: C

Rationale: The correct answer is Chloroquine phosphate (Aralen). Chloroquine is a medication used to prevent and treat malaria. It works by killing the malaria parasite in the red blood cells. Metronidazole (Flagyl) is an antibiotic used to treat various bacterial and parasitic infections, not malaria. Oprelvekin (Neumega) is a medication used to stimulate platelet production. Chloroprocaine hydrochloride (Nesacaine) is a local anesthetic used for epidural anesthesia. Therefore, Chloroquine phosphate is the appropriate medication for preventing malaria in this scenario.

Correct Answer: C

Rationale: When a patient is being treated with IV amphotericin B for a fungal infection, it is crucial to monitor the patient's calcium levels consistently. IV amphotericin B can cause hypokalemia, hypomagnesemia, and most notably, hypocalcemia. Monitoring calcium levels helps prevent drug-related discomfort and adverse effects. Sodium (Choice A), hemoglobin (Choice B), and leukocytes (Choice D) are not the primary parameters to monitor specifically for drug discomfort related to amphotericin B. Therefore, they are incorrect choices.

Correct Answer: B

Rationale: The correct answer is B. Axonal transport involves the movement of materials to the nerve terminal by either fast or slow components, which is essential for cell survival. Choice A is incorrect because while anterograde and retrograde axonal transport are involved in the movement of materials, they do not specifically relate to the communication of nerve impulses between a neuron and the CNS. Choice C is incorrect because the unidirectional nature of axonal transport does not primarily function to protect the CNS against pathogens. Choice D is incorrect as axonal transport is responsible for the movement of various materials, not just electrical impulses.

Correct Answer: A

Rationale: The correct answer is A. Parkinson's disease is caused by a deficiency of dopamine in the brain, which results in the characteristic motor symptoms such as tremors, rigidity, and bradykinesia. Choice B is incorrect because Parkinson's disease is not caused by an excess of acetylcholine. Choice C is incorrect because Parkinson's disease is not an autoimmune disorder. Choice D is incorrect because Parkinson's disease is not caused by a bacterial infection and cannot be treated with antibiotics.

Correct Answer: A

Rationale: The correct instruction for medroxyprogesterone acetate (Provera) is to take the medication at the same time each day to maintain consistent hormone levels and ensure its effectiveness. Choice B is incorrect because discontinuing the medication abruptly without consulting healthcare providers can be harmful. Choice C is incorrect as taking the medication with food is not necessary for this specific drug. Choice D is incorrect as medroxyprogesterone is typically taken orally, not applied topically.

Correct Answer: A

Rationale: The correct answer is A: Hepatotoxicity. Androgen therapy, such as testosterone, can lead to hepatotoxicity, which is toxic to the liver. Therefore, the nurse should monitor the patient's liver function. Choices B, C, and D are incorrect because androgen therapy is not typically associated with nephrotoxicity, cardiotoxicity, or pulmonary toxicity.
