Correct Answer: C

Rationale: Acyclovir (Zovirax) is specifically used to treat infections caused by herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) and varicella-zoster virus (VZV). These include conditions like cold sores, genital herpes, and shingles. Acyclovir works by inhibiting viral DNA replication, leading to the formation of shorter, ineffective DNA chains. It is important to note that acyclovir is not effective against other viruses like HIV, cytomegalovirus (CMV), or influenza A viruses.
Therefore, the correct answer is HSV 1 and 2 and VZV.

Correct Answer: B

Rationale: Alcoholism places a client at risk for developing cirrhosis due to the liver damage caused by excessive alcohol consumption. Type I diabetes, leukemia, and glaucoma are not directly associated with cirrhosis. While diabetes can lead to other health complications, it does not directly cause cirrhosis. Leukemia is a type of blood cancer that does not affect the liver in a way that leads to cirrhosis. Glaucoma is an eye condition that has no direct link to cirrhosis.

Correct Answer: B

Rationale: The correct answer is that chemotherapy is a systemic treatment affecting both tumor and normal cells. 5-FU, as an antimetabolic drug, inhibits DNA synthesis and interferes with cell replication systemically. It affects all rapidly growing cells, including malignant and normal ones. This drug is used as adjuvant therapy for various cancers.
Choice A is incorrect because chemotherapy affects both tumor and normal cells, not just tumor cells.
Choice C is incorrect as chemotherapy has been proven effective in treating cancer.
Choice D is incorrect because chemotherapy often causes side effects like bone marrow depression, anorexia, stomatitis, nausea, and vomiting.

Correct Answer: A

Rationale: Objective anthropometric measurements such as triceps skinfold and mid-arm circumference (MA
C), along with weight, are usually used to diagnose malnutrition. Triceps skinfold measurement specifically helps assess body fat and muscle mass, providing valuable information about the client's nutritional status. Fasting blood glucose level, hemoglobin A1c level, and serum lipid profile results are important tests in assessing different aspects of health such as diabetes management and cardiovascular risk, but they are not specific indicators of malnutrition.

Correct Answer: C

Rationale: A diet high in fiber content can help lower cholesterol levels. Fiber-rich foods such as grains, apples, potatoes, and beans are known to aid in reducing cholesterol by binding to cholesterol in the digestive system and preventing its absorption into the bloodstream.
Choice A is incorrect as the question does not specify losing weight rapidly but rather focuses on the benefits of a high-fiber diet, which includes aiding in weight management through promoting satiety and regulating digestion.
Choice B is incorrect because while fiber helps manage blood sugar levels, it is not directly related to reducing diabetic ketoacidosis, a serious complication of diabetes.
Choice D is incorrect as a high-fiber diet does not reduce the need for folate; however, it can aid in the absorption of folate and other essential nutrients.
