A nurse is reinforcing teaching with a client about heart disease prevention. Which of the following client statements indicates an understanding of the teaching?
"I will increase my dairy intake by drinking whole milk with every meal."
"I will improve my LDL cholesterol by raising it from 100 to 130."
"I will exercise by walking twice a week for 25 minutes."
"I will try to maintain my blood pressure around 116/72."
The Correct Answer is D
"I will try to maintain my blood pressure around 116/72." This is because maintaining blood pressure within a normal range can help prevent heart disease. Choice A is incorrect because increasing dairy intake can lead to a higher intake of saturated fats which can increase the risk of heart disease.
Choice B is incorrect because lowering, not raising, LDL cholesterol is essential in preventing heart disease.
Choice C is incorrect because exercising only twice a week for 25 minutes is not enough to prevent heart disease.
An explanation for why the other choices are not answers: A – Increasing dairy intake can lead to a higher intake of saturated fats which can increase the risk of heart disease, so this is not the correct statement. B – Lowering, not raising, LDL cholesterol is essential in preventing heart disease, so this is not the correct statement. C – Exercising only twice a week for 25 minutes is not enough to prevent heart disease. Thus, this is not the correct statement.

Correct Answer is B
Explanation
The correct answer is choice B: Store opened insulin vials at room temperature for up to 4 weeks.
Choice B rationale: Opened insulin vials can be stored at room temperature (59°F to 86°F or 15°C to 30°C) for up to 4 weeks. After this period, the insulin may lose potency, and a new vial should be used.
Choice A rationale: Regular insulin is short-acting, and its peak effect occurs 2 to 3 hours after administration. Eating a snack 6 hours after insulin administration may not be necessary as the insulin would have already reached its peak effect, and blood glucose levels should be monitored accordingly.
Choice C rationale: Warming the insulin vial to dissolve crystals is not recommended. Insulin should be inspected before use, and if crystals or clumps are present, it should be discarded as this could indicate that the insulin has lost its effectiveness.
Choice D rationale: Unopened insulin vials should be stored in the refrigerator (36°F to 46°F or 2°C to 8°C) and should not be frozen. Freezing can cause insulin to lose potency or become ineffective. Once opened, insulin vials can be stored at room temperature for up to 4 weeks, as mentioned in choice B.
