A client with diabetes is experiencing hyperglycemia. What is the nurse's priority?

Correct Answer: A

Rationale: The correct answer is to administer insulin. In hyperglycemia, there is an excess of glucose in the blood, which needs to be lowered. Insulin is the primary medication used to lower blood glucose levels by facilitating the uptake of glucose into cells. Encouraging the client to exercise may further increase blood glucose levels due to the release of stress hormones, so it is not the priority. While staying hydrated is important, it will not directly address the high blood glucose levels seen in hyperglycemia. Glucagon is used to treat severe hypoglycemia, not hyperglycemia, so it is not the priority in this situation.

Correct Answer: C

Rationale: Performing a wound culture before applying ointment is crucial when providing wound care to a client with a pressure ulcer. This action helps identify any underlying infections, allowing healthcare providers to select the most appropriate treatment. Options A, B, and D are not as critical as performing a wound culture, as they focus on wound dressing and cleansing rather than identifying potential infections.

Correct Answer: D

Rationale: The nurse should prioritize performing a wound culture before administering antibiotics to ensure appropriate treatment. This step helps identify the specific infecting organism and its susceptibility to different antibiotics, guiding effective antibiotic therapy. Changing the dressing daily (Choice A) is important but comes after assessing the infection and initiating appropriate treatment. Cleansing the wound with an antiseptic solution (Choice B) and applying a wet-to-dry dressing (Choice C) are interventions that may be necessary but are secondary to determining the most suitable antibiotic therapy based on the wound culture results.

Correct Answer: B

Rationale: Performing a wound culture before administering antibiotics is crucial when managing a client with a wound infection. This step helps identify the specific pathogens causing the infection, allowing for the prescription of the most effective antibiotics. Changing the wound dressing every 24 hours (Choice A) is important for wound care but not the priority when an infection is present. Cleansing the wound with alcohol-based solutions (Choice C) can be too harsh and may delay wound healing. Applying a wet-to-dry dressing (Choice D) is not recommended for infected wounds as it can cause trauma to the wound bed during dressing changes.

Correct Answer: B

Rationale: The correct lifestyle change that should be emphasized for a client with hypertension is to reduce caffeine and sodium intake. Caffeine can temporarily raise blood pressure, and high sodium intake is linked to increased blood pressure levels. Therefore, reducing these two components can help manage blood pressure in individuals with hypertension. Choices A, C, and D are incorrect because increasing intake of dairy products, consuming carbohydrate-rich meals, and limiting intake of leafy green vegetables do not specifically address the factors that contribute to high blood pressure in hypertension.
