Correct Answer: C

Rationale: The correct answer is C: Myotic. Myotic eyedrops constrict the pupil, allowing aqueous humor to flow around the lens. Myotic agents, such as pilocarpine, work by stimulating the sphincter muscle of the iris. Osmotic eyedrops (A) reduce intraocular pressure, mydriatic eyedrops (B) dilate the pupil, and cycloplegic eyedrops (D) paralyze the ciliary muscle to prevent accommodation.

Correct Answer: A

Rationale: The correct answer is A because asthma is characterized by inflammation and bronchoconstriction of the airways, leading to difficulty breathing. This explanation accurately describes the pathophysiology of asthma. Explanation for other choices: B: Fluid in the lungs is more indicative of conditions like pneumonia or pulmonary edema, not asthma. C: Asthma involves airway constriction and inflammation, not stretching and non-functionality. D: Asthma is not caused by infection but rather triggered by factors like allergens or irritants.

Correct Answer: B

Rationale: The correct answer is B: Amenorrhea. Danazol is a synthetic steroid used to treat fibrocystic breast disease by suppressing ovulation and hormonal fluctuations. This leads to a decrease in menstrual bleeding, resulting in amenorrhea. Nausea and confusion are not common adverse reactions of danazol. Hypotension is also not associated with danazol use. In summary, amenorrhea is the expected side effect due to the drug's mechanism of action, making it the correct choice compared to the other options.

Correct Answer: A

Rationale: The correct answer is A: Muscle weakness. After unilateral adrenalectomy, there is a risk of hyperkalemia due to decreased aldosterone production. Aldosterone helps regulate potassium levels in the body. Muscle weakness is a common symptom of hyperkalemia as high potassium levels can affect muscle function. Diaphoresis, tremors, and constipation are not typically associated with hyperkalemia. Diaphoresis is excessive sweating, tremors are involuntary muscle movements, and constipation is difficulty passing stool. These symptoms are not directly related to potassium imbalance.

Correct Answer: C

Rationale: The correct answer is C because using an electric razor instead of a safety razor demonstrates understanding of the risk of injury associated with thrombocytopenia. This action shows practical application of the teaching to prevent bleeding. Choice A only indicates awareness but not necessarily action. Choice B shows knowledge but not necessarily application. Choice D is related to general healthcare knowledge but not directly linked to bleeding prevention in thrombocytopenia.
