Correct Answer: C

Rationale: The correct answer is chronic alcoholism. Chronic alcoholism is a significant risk factor for pancreatic cancer due to its impact on the pancreas. Chewing tobacco (choice A) is more associated with oral and throat cancers, not pancreatic cancer. A low-fat diet (choice B) is actually considered a protective factor against pancreatic cancer. Exposure to industrial chemicals (choice D) may be a risk factor for other types of cancer but is not strongly linked to pancreatic cancer.

Correct Answer: A

Rationale: The correct answer is A, weight loss. Metformin is commonly associated with weight loss rather than weight gain. Metformin works by decreasing glucose production in the liver and improving insulin sensitivity, which can lead to weight loss in some individuals. Choices B, C, and D are incorrect. Weight gain is not a typical side effect of metformin. Drowsiness and hypertension are also not commonly associated with metformin use.

Correct Answer: D

Rationale: The correct answer is D, High-density lipoprotein (HDL). HDL is known as 'good' cholesterol because it helps transport excess cholesterol from tissues back to the liver for removal from the body. Very low-density lipoprotein (VLDL) (choice A) and intermediate-density lipoprotein (choice B) are involved in transporting triglycerides. Low-density lipoprotein (LDL) (choice C) is known as 'bad' cholesterol as it can deposit cholesterol in the walls of arteries.

Correct Answer: D

Rationale: The correct interventions for a client with peripheral vascular disease include keeping the area between the toes dry to prevent moisture-related skin issues and wearing comfortable, well-fitting shoes to prevent injury and promote circulation. Cutting toenails straight across is important to prevent ingrown toenails, but in this case, an arch cut can lead to injury. Therefore, choices A and B are correct, making option D the most appropriate answer. Choice C is incorrect in this context.

Correct Answer: A

Rationale: Corrected Rationale: Before sputum collection, it is crucial to use a clean container to prevent specimen contamination. This step is essential to ensure accurate test results and to avoid introducing external particles or bacteria into the sample. Choice B is incorrect because discarding the container if the outside becomes soiled is not a standard practice before collection. Choice C is incorrect as rinsing the client's mouth with Listerine after collection can introduce unnecessary substances into the specimen. Choice D is incorrect as the amount of sputum needed should be determined by the healthcare provider, not the client.
