Question 1 of 5
Parenteral furosemide is an alternative diuretic to mannitol in the following condition
Correct Answer: C
Rationale: Furosemide can be used in cerebral edema to reduce intracranial pressure when mannitol is not suitable.
Question 2 of 5
Diethylstilbestrol (DES) should never be used in pregnant women because it is associated with all of the following EXCEPT:
Correct Answer: A
Rationale: DES, a synthetic estrogen, causes deep vein thrombosis (choice A), feminization of male offspring (choice B), and miscarriages (choice C) in pregnancy, linked to historical congenital anomalies (e.g., vaginal adenocarcinoma). Virilization of female offspring (choice D) isn't reported; DES mimics estrogen, not androgens. This exception highlights its teratogenic risks, banning its use in pregnancy.
Question 3 of 5
Which of the following is useful in treatment of trigeminal neuralgia:
Correct Answer: D
Rationale: Carbamazepine (choice D), an anticonvulsant, treats trigeminal neuralgia by stabilizing sodium channels, reducing nerve firing. Phenylbutazone (choice A), an NSAID, and Morphine (choice B), an opioid, aren't first-line. Atropine (choice C), an anticholinergic, is irrelevant. Carbamazepine is the standard therapy.
Question 4 of 5
A physician has a choice in benzodiazepines to prescribe for patients. A particular patient (a 53-year-old man with anxiety) has a difficult time with compliance to medications. The physician is concerned about the patient going into withdrawal because of abrupt discontinuation of the antianxiety medication. Which of the following medications would have the least severe withdrawal reaction?
Correct Answer: A
Rationale: Diazepam has a long half-life, which reduces the risk of severe withdrawal symptoms compared to shorter-acting benzodiazepines like triazolam.

A 73-year-old man presents to his primary care physician complaining of a weak stream and nocturia four times at night. He is very sensitive to the medication side effects and is reluctant to take medications for this reason. Physical examination reveals a mildly enlarged prostate. Treatment of this condition may involve the use of which of the following agents to minimize side effects?
Correct Answer: D
Rationale: Tamsulosin is an α1-adrenergic receptor antagonist that is selective for the prostate and bladder neck, minimizing systemic side effects like hypotension.
