Aminocapronic acid is a drug of choice for treatment of:

Correct Answer: B

Rationale: The correct answer is B: Bleeding from fibrinolytic therapy. Aminocaproic acid is an antifibrinolytic agent that works by inhibiting the breakdown of blood clots. It is commonly used to manage excessive bleeding caused by fibrinolytic therapy, such as in cases of severe bleeding post-surgery or trauma. This drug helps to maintain clot stability and prevent further bleeding. Incorrect choices: A: Acute myocardial infarction - Aminocaproic acid is not indicated for the treatment of acute myocardial infarction. C: Heart failure - Aminocaproic acid is not used in the treatment of heart failure. D: Multiple pulmonary emboli - Aminocaproic acid is not typically used to treat multiple pulmonary emboli.

Correct Answer: C

Rationale: The correct answer is C: Angiotensin II. Angiotensin II is an endogenous vasoconstrictor that can stimulate aldosterone release from the suprarenal glands. It is formed from the conversion of Angiotensin I by Angiotensin-converting enzyme (ACE). Angiotensinogen (choice A) is the precursor protein that is converted to Angiotensin I. Angiotensin-converting enzyme (choice D) is responsible for converting Angiotensin I to Angiotensin II, not for directly stimulating aldosterone release.

Correct Answer: C

Rationale: The correct answer is C: Prolactin deficiency. Bromocriptine is a dopamine agonist used to treat conditions caused by excessive prolactin secretion, such as prolactin-secreting adenomas, amenorrhea-galactorrhea, and acromegaly. Prolactin deficiency would not be an indication for bromocriptine as it works by decreasing prolactin levels. Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they are all conditions where bromocriptine would be indicated based on its mechanism of action in reducing prolactin levels.

Correct Answer: C

Rationale: Rationale: 1. Ethinyl estradiol is a synthetic estrogen, not a natural estrogen. 2. Estradiol, estrone, and estriol are natural estrogens produced by women. 3. Ethinyl estradiol is commonly found in birth control pills. 4. Estrogen-17β is the form of estrogen predominantly produced by women. Summary: Ethinyl estradiol is the correct answer because it is a synthetic estrogen, unlike estradiol, estrone, and estriol, which are natural estrogens produced by women.

Correct Answer: C

Rationale: Rationale: Aspirin is not indicated for relieving severe visceral pain like myocardial infarction, cancer pain, renal or biliary colic. Aspirin is primarily used for its anti-inflammatory and antiplatelet effects, making choices A, B, and D correct indications. Choice C is incorrect as aspirin is not a preferred analgesic for visceral pain.
