A client with a history of diabetes mellitus is admitted with a foot ulcer. The nurse should recognize that which intervention is most critical in promoting healing of the foot ulcer?

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Strict control of blood glucose levels is critical in promoting healing of foot ulcers in diabetic patients. 2. High blood glucose levels can impair wound healing by affecting circulation and immune response. 3. Maintaining normal glucose levels helps optimize tissue repair and prevent further complications. 4. Regular dressing changes (B) are important but not as critical as controlling blood glucose levels. 5. Application of antibiotic ointment (C) may be necessary for infected ulcers, but not the most critical intervention. 6. Hydrotherapy treatment (D) can help with wound cleansing, but it is not as essential as controlling blood glucose levels.

Correct Answer: B

Rationale: The correct answer is B: Limit caffeine and alcohol consumption. Hot flashes can be triggered by stimulants like caffeine and alcohol. Limiting intake can help reduce their occurrence. Increasing spicy foods (A) can actually worsen hot flashes. High-protein diets (C) and consuming more dairy products (D) do not have a direct impact on hot flashes.

Correct Answer: A

Rationale: The correct answer is A: Use a soft-bristled toothbrush. Chemotherapy can cause low platelet levels, increasing the risk of bleeding. Using a soft-bristled toothbrush can help prevent gum bleeding and trauma to the gums, reducing the risk of bleeding. Engaging in daily aerobic exercise (B) can increase the risk of injury and bleeding for a client with thrombocytopenia. Taking aspirin (C) can further decrease platelet function and increase bleeding risk. Using an electric razor (D) is recommended to prevent skin cuts and bleeding due to the fragile skin associated with chemotherapy-induced thrombocytopenia.

Correct Answer: B

Rationale: The correct answer is B because nitroglycerin tablets should be stored in a dark, glass container to protect them from light and moisture, which could decrease their effectiveness. Storing them in any other container could lead to degradation of the medication. Choice A is incorrect because nitroglycerin should be taken sublingually, not with food. Choice C is incorrect because nitroglycerin should be placed under the tongue to be absorbed quickly, not swallowed whole. Choice D is incorrect because experiencing a headache is a common side effect of nitroglycerin and does not indicate that the medication should be discontinued.

Correct Answer: A

Rationale: The correct answer is A: Administer pain medication as prescribed. This is the highest priority because acute pancreatitis is a painful condition, and managing pain is crucial for the client's comfort and well-being. Pain control also helps reduce stress on the pancreas and can aid in preventing complications. Choice B is incorrect because while monitoring serum amylase and lipase levels is important in diagnosing pancreatitis and assessing response to treatment, it is not the highest priority intervention. Choice C is incorrect as encouraging oral intake of clear liquids may exacerbate pancreatitis symptoms and lead to further complications. Choice D is incorrect as assessing bowel sounds, while important for monitoring gastrointestinal function, is not the highest priority in the acute management of pancreatitis.
