The nurse mixes diphenhydramine 25 mg in a 100 mL bag of 0.9% sodium chloride, which is to be administered IV over 30 minutes. The IV pump should be set to administer how many mL/hour? (Enter numeric value only.)

Answer and Explanation

The Correct Answer is ["200"]

Identify the total volume to be infused.

Total volume = 100 mL

Identify the infusion time in minutes.

Infusion time = 30 minutes

Convert the infusion time to hours.

Infusion time (hours) = Infusion time (minutes) / 60 minutes/hour

= 30 minutes / 60 minutes/hour

= 0.5 hours

Calculate the infusion rate in mL per hour.

Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours)

= 100 mL / 0.5 hours

= 200 mL/hour

Correct Answer is C

Explanation

A. Notify the healthcare provider if anorexia occurs: Anorexia can be a side effect of exenatide, but it is generally mild and often transient. While persistent or severe anorexia should be reported, it is not the most immediate or dangerous concern compared to the risk of hypoglycemia when combining exenatide with a sulfonylurea like glimepiride.

B. Consume additional sources of potassium: Exenatide is not known to cause significant potassium depletion. Hypokalemia is not a common complication with either exenatide or glimepiride therapy, so there is no specific need to focus on increasing potassium intake.

C. Watch for signs of jitteriness or diaphoresis: Combining exenatide with glimepiride significantly increases the risk of hypoglycemia. Symptoms like jitteriness, diaphoresis, shakiness, and confusion are hallmark signs of low blood sugar, making it crucial to educate the client to recognize and manage hypoglycemia promptly.

D. Administer subcutaneously after meals: Exenatide should be administered subcutaneously, but it must be given before meals, typically within 60 minutes prior to eating. Administering it after meals would decrease its effectiveness in controlling postprandial blood glucose spikes.

A. Print an electrocardiogram strip B. Call for rapid response C. Perform chest compressions D. Apply oxygen via nasal cannula E. Give naloxone 2 mg intravenous push F. Provide rescue breaths with a manual ventilation bag

Correct Answer is ["B","E","F"]

Explanation

A. Print an electrocardiogram strip: While cardiac monitoring is important, printing an ECG strip does not immediately address the critical issue of respiratory depression and unresponsiveness. Priority actions must focus on airway and breathing first.

B. Call for rapid response: The client is critically unstable with severe respiratory depression and unresponsiveness, meeting criteria for a rapid response or even a code blue if the situation deteriorates further. Immediate expert team support is crucial.

C. Perform chest compressions: Chest compressions are only indicated if the client is pulseless. In this case, the client has a heart rate of 92 beats/minute, meaning compressions are not appropriate at this moment.

D. Apply oxygen via nasal cannula: A nasal cannula would not deliver high enough oxygen concentrations for someone with a respiratory rate of 5 breaths/minute and oxygen saturation of 54%. Higher oxygen delivery methods and ventilatory support are urgently needed.

E. Give naloxone 2 mg intravenous push: Naloxone is indicated immediately to reverse opioid-induced respiratory depression. Giving the prescribed naloxone IV push can rapidly counteract the morphine overdose and improve the client’s respiratory effort.

F. Provide rescue breaths with a manual ventilation bag: Because the client’s respirations are critically low, rescue breathing with a manual resuscitation bag is necessary to maintain oxygenation and ventilation until naloxone takes effect or more advanced airway management is available.
