Correct Answer: C

Rationale: The correct answer is C: Place the patient on respiratory isolation and inform the physician. This is the most appropriate action because the patient is exhibiting symptoms that could be indicative of a potentially infectious respiratory condition, such as tuberculosis or pneumonia. Placing the patient on respiratory isolation helps prevent the spread of infection to others and protects healthcare workers. Informing the physician promptly allows for further evaluation and appropriate treatment. Choice A is incorrect as Kaposi's sarcoma typically presents with skin lesions rather than respiratory symptoms. Choice B is incorrect as reviewing viral load and CD4+ count would not address the immediate concern of respiratory symptoms. Choice D is incorrect as oral suctioning is not the appropriate intervention for night sweats and coughing up blood.

Correct Answer: A

Rationale: The correct answer is A: Abstaining from sexual intercourse for at least 14 days postprocedure. This is important to allow the surgical site to heal properly and reduce the risk of complications. Choice B, wearing a scrotal support garment, can provide comfort but does not directly enhance healing. Choice C, using sitz baths, may help with discomfort but may not specifically promote healing. Choice D, applying a heating pad intermittently, could potentially increase the risk of infection. Choice E, staying on bed rest for 48 to 72 hours postprocedure, is unnecessary and could lead to complications such as blood clots.

Correct Answer: B

Rationale: The correct initial intervention for a chemical burn to the eye is to generously flush the affected eye with normal saline or water. Flushing helps to remove the chemical from the eye, preventing further damage. Antibiotic solution (choice A) is not the first intervention as the priority is to remove the chemical. Applying a patch (choice C) can trap the chemical against the eye, worsening the injury. Applying direct pressure (choice D) is not appropriate and can cause additional harm. Flushing with normal saline or water is the most effective and safest initial intervention to minimize damage from a chemical burn to the eye.

Correct Answer: A

Rationale: Step 1: Serous otitis media is common in children due to eustachian tube dysfunction, not usually related to systemic infections. Step 2: Recurrent infections may indicate age-related changes like decreased eustachian tube function. Step 3: Age-related physiologic changes can lead to poor drainage, causing recurrent otitis media. Step 4: Therefore, choice A is correct as it aligns with the typical presentation of serous otitis media in the context of age. Summary: Choice B is incorrect as there is no indication for temporary mobility restriction. Choice C is incorrect as serous otitis media does not typically warrant assessment for nasopharyngeal cancer. Choice D is incorrect as blood cultures are not typically indicated for serous otitis media.

Correct Answer: B

Rationale: The correct answer is B: There is no noticeable decrease in the amount of ejaculate even though it contains no sperm. After a vasectomy, the vas deferens, the tube that carries sperm from the testicles, is cut or blocked. This prevents sperm from being ejaculated, but the seminal fluid produced by the prostate and other glands still makes up the majority of the ejaculate volume. Therefore, although the ejaculate does not contain sperm after a vasectomy, there is no significant change in the amount of fluid ejaculated. Choice A is incorrect because the absence of sperm does not impact the volume of ejaculate. Choice C is incorrect as there is no marked decrease in ejaculate volume. Choice D is incorrect as there is no evidence to suggest that the viscosity of ejaculate changes post-vasectomy.
