Correct Answer is A

Explanation

The nurse should instruct the client to avoid taking medications for erectile dysfunction, such as sildenafil, within 24 hours of taking nitroglycerin due to the risk of severe hypotension.

Reasons why the other options are not answers:

Option B: Metformin is not contraindicated with nitroglycerin.

Option C: Omeprazole is not contraindicated with nitroglycerin.

Option D: Atorvastatin is not contraindicated with nitroglycerin.

A. Plan to eat a snack 6 hours after insulin administration. B. Store opened insulin vials at room temperature for up to 4 weeks. C. Warm the insulin vial to dissolve any crystals that develop. D. Keep unopened insulin vials in the freezer.

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.
