A patient comes to the clinic for a herpes-zoster infection? (Select all that apply)

Amphotericin B

Acyclovir

An azole group

Tamiflu

Answer and Explanation

The Correct Answer is B

Choice A reason:
Amphotericin B is an antifungal medication and is not used to treat viral infections such as herpes-zoster. This choice is incorrect because it does not target the herpes virus, which causes conditions like shingles.
Choice B reason:
Acyclovir is an antiviral medication specifically used to treat infections caused by the herpes virus, including herpes-zoster (shingles). It works by inhibiting viral replication, reducing the severity and duration of symptoms. This makes it the correct choice for treating herpes-zoster infection.
Choice C reason:
Azole antifungals are used to treat fungal infections, not viral infections like herpes-zoster. This choice is incorrect as it does not relate to the treatment of the herpes virus.
Choice D reason:
Tamiflu is an antiviral medication used to treat influenza, not herpes-zoster. While it targets a viral infection, it is specific to the influenza virus and not effective against the herpes virus. Therefore, this choice is incorrect.

Correct Answer is D

Explanation

Choice A reason:
Nonadherence to the antiviral regimen could result in suboptimal control of the HIV infection, but it is not typically associated with symptoms of increased hunger, thirst, and frequent urination. Therefore, this choice does not explain the patient's symptoms.
Choice B reason:
An allergic reaction might cause a variety of symptoms, such as rash, itching, or swelling, but it would not typically cause increased hunger, thirst, and frequent urination. This choice is incorrect as it does not align with the presented symptoms.
Choice C reason:
Pancreatic infiltration by HIV is a rare and serious condition that can lead to various metabolic complications, but it is not a common cause of the specific symptoms described (increased hunger, thirst, and frequent urination). This choice is not consistent with the patient's symptoms.
Choice D reason:
Hyperglycemia, or high blood sugar, can cause symptoms like increased hunger, thirst, and frequent urination. These symptoms are indicative of diabetes, which can be a side effect of some antiviral medications, particularly protease inhibitors used in HIV treatment. Therefore, this choice accurately reflects the patient's symptoms and is the correct answer.

A. True B. False

Correct Answer is True

Explanation

Choice A reason:

True is the correct answer. Cardiac cells can endure ischemic conditions for approximately 20 minutes before irreversible injury occurs. Beyond this period, the lack of oxygen and nutrients leads to cell death and permanent damage to the heart tissue. This understanding is crucial in acute cardiac care, where timely intervention can prevent irreversible damage.

Choice B reason:

False is incorrect because it does not align with the known tolerance period of cardiac cells to ischemic conditions. The 20-minute window is critical for initiating interventions that can save heart tissue from permanent damage.
