A nurse is reinforcing discharge teaching with a client regarding selfadministration of regular insulin. What instruction should the nurse include?

Plan to eat a snack 6 hours after insulin administration.

Store opened insulin vials at room temperature for up to 4 weeks.

Warm the insulin vial to dissolve any crystals that develop.

Keep unopened insulin vials in the freezer.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is C

Explanation

The correct answer is choice C: Blood pressure change from 118/78 mm Hg to 86/50 mm Hg.

Choice C rationale: A significant drop in blood pressure can indicate various serious conditions, such as shock, hemorrhage, or a severe infection. The nurse should assess the client further and intervene as necessary to prevent complications.

Choice A rationale: The change in temperature may indicate the onset of a fever and requires further assessment, but it is not as immediately concerning as the sudden drop in blood pressure.

Choice B rationale: The change in respiratory rate could be a result of factors like pain, anxiety, or exercise. While it warrants further assessment, it is not as critical as the blood pressure change.

Choice D rationale: The heart rate change may be a response to medications, rest, or other factors. It should be monitored and assessed, but the priority finding is the blood pressure change, which may indicate a more severe underlying issue.

A. "I will take four nitroglycerin sublingual tablets if I have chest pain." B. "I will have hot, dry, and flushed skin if I am having a heart attack." C. "I will wait 30 minutes before taking action if I have heartburn." D. "I will notify emergency response if I have sudden jaw pain."

Correct Answer is D

Explanation

This response indicates that the client understands that sudden jaw pain can be a sign of a heart attack and requires immediate medical attention.

A. "I will take four nitroglycerin sublingual tablets if I have chest pain." This is an incorrect statement because taking four nitroglycerin sublingual tablets can lead to hypotension and can be life-threatening.

B. "I will have hot, dry, and flushed skin if I am having a heart attack." This is an incorrect statement because hot, dry, and flushed skin is not a typical sign of a heart attack.

C. "I will wait 30 minutes before taking action if I have heartburn." This is an incorrect statement because heartburn is not a symptom of angina and waiting 30 minutes to take action can lead to further complications.

Explanation: The client with angina should be educated about the signs and symptoms of a heart attack and when to seek medical attention. Jaw pain is one of the signs of a heart attack, and the client should seek emergency medical attention immediately.
