Correct Answer: A

Rationale: The correct answer is A: Administer nitroglycerin. Nitroglycerin is the recommended initial medication for chest pain in a client with a history of myocardial infarction. It helps dilate blood vessels, improving blood flow to the heart, and reducing chest pain. Aspirin (choice B) is also usually given to reduce blood clot formation, but nitroglycerin is the priority for immediate relief. Morphine (choice C) may be used if nitroglycerin is ineffective, and beta blockers (choice D) are typically used for long-term management of heart conditions, not for immediate relief of chest pain.

Correct Answer: B

Rationale: Acyclovir is a nucleoside analog antiviral drug that is specifically effective against herpes simplex virus (HSV) types 1 and 2, as well as varicella-zoster virus (VZV). The drug works by inhibiting viral DNA synthesis. HSV and VZV are both members of the herpes virus family, and acyclovir is most commonly prescribed for infections caused by these viruses. Therefore, the correct answer is B. Choice A (HIV) is incorrect because acyclovir is not effective against HIV. Choice C (CMV) is incorrect because acyclovir is less effective against cytomegalovirus (CMV) compared to HSV and VZV. Choice D (influenza A viruses) is incorrect because acyclovir is not indicated for the treatment of influenza viruses.

Correct Answer: B

Rationale: The correct answer is B: Encouraging deep breathing and coughing exercises. This is prioritized in the immediate post-operative period to prevent respiratory complications like atelectasis and pneumonia. Deep breathing helps to expand the lungs and coughing helps clear secretions. Administering pain medication (A) is important but not the top priority. Monitoring for signs of infection (C) is crucial but usually done after ensuring respiratory stability. Providing solid food (D) is contraindicated initially to prevent post-operative complications like ileus.

Correct Answer: A

Rationale: The correct answer is A: Assess the client's airway. This is the first action because airway patency is the top priority in any emergency situation, including a suspected stroke. Ensuring the client can breathe effectively is crucial to prevent hypoxia and further complications. Administering oxygen (choice B) may be necessary after assessing the airway. Administering aspirin (choice C) should be done after a definitive diagnosis of an ischemic stroke. Performing a CT scan (choice D) is important for diagnosis but is not the first action to take in a suspected stroke scenario.

Correct Answer: A

Rationale: The correct answer is A: Psoriasis. Psoriasis is characterized by red, scaly patches on the skin, which align with the symptoms described. Psoriasis commonly affects the lower legs and is associated with severe itching. Eczema (choice B) is characterized by red, inflamed, and itchy skin patches, but typically presents differently from psoriasis. Contact dermatitis (choice C) is a localized reaction that occurs when the skin comes into contact with an irritant or allergen, and fungal infections (choice D) typically present with itching, redness, and sometimes peeling skin, but not necessarily scaly patches like psoriasis.
