A nurse is assessing a client who is receiving metoprolol. Which of the following indicates a therapeutic effect?

Choice A reason:

Place a black tag on the client’s upper body and attempt to help the next client in need: In mass casualty incidents, triage is used to prioritize treatment based on the severity of injuries and the likelihood of survival. A black tag indicates that the victim is deceased or has injuries that are not compatible with life and that resources should be directed to those who have a better chance of survival. Since the client remains apneic even after repositioning the airway, it indicates that they are not breathing and have a very low chance of survival.

Choice B reason:

Reposition the client’s upper airway a second time before assessing his respirations: While ensuring the airway is open is crucial, if the client remains apneic after the initial repositioning, further attempts are unlikely to be successful in a mass casualty scenario where time and resources are limited2. The priority is to move on to other victims who may have a higher chance of survival.

Choice C reason:

Start CPR: In a mass casualty situation, CPR is typically not initiated for victims who are apneic and pulseless due to the need to allocate resources to those who have a higher likelihood of survival3. The focus is on providing immediate care to those who can benefit the most from it.

Choice D reason:

Place a red tag on the client’s upper body and obtain immediate help from other personnel: A red tag is used for victims who require immediate life-saving interventions and have a high chance of survival if treated promptly4. Since the client is apneic and remains so after airway repositioning, they do not meet the criteria for a red tag.

Choice A reason:

0730: Regular insulin, also known as short-acting insulin, typically begins to work within 30 minutes after administration. Therefore, ensuring the client receives breakfast at 0730, which is 15 minutes after the insulin dose, aligns with the onset of insulin action. This timing helps to prevent hypoglycemia by ensuring that glucose from the meal is available when the insulin starts to lower blood sugar levels.

Choice B reason:

0745: Administering breakfast at 0745, which is 30 minutes after the insulin dose, might be slightly delayed. While it is still within the effective window, it is better to have the meal a bit earlier to ensure that glucose is available as soon as the insulin begins to act.

Choice C reason:

0815: Providing breakfast at 0815, which is an hour after the insulin dose, is too late. By this time, the insulin would have already started to lower blood glucose levels significantly, increasing the risk of hypoglycemia. It is crucial to match the timing of food intake with the insulin action to maintain stable blood sugar levels.

Choice D reason:

0720: Serving breakfast at 0720, which is only 5 minutes after the insulin dose, is too early. The insulin would not have started to act yet, and the blood glucose levels might rise too high before the insulin begins to lower them. It is important to wait at least 15-30 minutes after administering regular insulin before eating.
