Correct Answer: C

Rationale: The correct answer is C: Permanent vascular damage. Priapism is a prolonged erection that can lead to ischemia and damage to the penile tissue due to impaired blood flow, potentially resulting in permanent vascular damage. Urinary tract infection (A) is unrelated to priapism. Chronic pain (B) may occur but is not the primary concern. Future erectile dysfunction (D) can result from priapism but is not as immediate or severe as permanent vascular damage. Therefore, C is the most critical consequence to address in priapism.

Correct Answer: B

Rationale: The correct answer is B: Cholinergics. Glaucoma is a condition characterized by increased intraocular pressure due to impaired drainage of aqueous humor. Cholinergics help to constrict the pupil and improve the outflow of aqueous humor, thus reducing intraocular pressure. This medication class is commonly used to manage glaucoma. A: Potassium-sparing diuretics are not typically used in the treatment of glaucoma. They are mainly used to manage conditions like hypertension and heart failure. C: Antibiotics are not indicated for the routine management of glaucoma. They are used to treat infections. D: Loop diuretics are not commonly used in the treatment of glaucoma. They are primarily used to manage conditions like edema and hypertension.

Correct Answer: D

Rationale: The correct answer is D, marginal. Placenta previa is classified based on the proximity of the placental edge to the internal os. In a marginal placenta previa, the placental edge just reaches the internal os. This is a crucial distinction as it poses a higher risk for bleeding during labor. Total placenta previa covers the entire internal os, partial placenta previa partially covers the internal os, and low-lying placenta is when the placenta is close to but not covering the internal os. Therefore, D is correct as it accurately describes the specific position of the placenta edge in relation to the internal os in cases of marginal placenta previa.

Correct Answer: B

Rationale: The correct answer is B: Flex head with chin tuck. This position helps prevent aspiration by closing off the airway during swallowing. Flexing the head and tucking the chin promotes safe swallowing and reduces the risk of choking. Placing food on the left side (choice C) is not relevant to addressing the patient's symptoms. Positioning in semi-Fowler's (choice A) may not directly address the swallowing difficulty. Offering fruit juice (choice D) does not address the patient's specific feeding needs and may not be safe if the patient has swallowing difficulties.

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.
