Ethyl alcohol is an agent decreasing appetite. It’s:

Correct Answer: B

Rationale: Rationale: 1. Ethyl alcohol is a substance known to stimulate appetite, not decrease it. 2. Alcohol consumption often leads to increased hunger and overeating. 3. Therefore, the correct answer is B: FALSE. Summary: A: Incorrect - Ethyl alcohol does not decrease appetite. C: Incorrect - Ethyl alcohol does not decrease appetite for all individuals. D: Incorrect - Ethyl alcohol does have an impact on appetite.

Correct Answer: D

Rationale: Rationale: Nifedipine is a dihydropyridine calcium channel blocker primarily used for hypertension and angina, not for cardiac arrhythmias. Bepridil, Diltiazem, and Verapamil are non-dihydropyridine calcium channel blockers that are effective in treating cardiac arrhythmias by slowing down the heart rate and controlling abnormal heart rhythms. Nifedipine does not possess significant antiarrhythmic properties compared to the other options, making it the incorrect choice for the treatment of cardiac arrhythmias.

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.
