Which client statement indicates understanding of the use of an external insulin pump?
“I will leave this on when bathing or swimming”
“I will still need to monitor my blood glucose levels.”
“I will not need to count carbohydrates anymore.”
“Having an insulin pump will help me lose weight.”
The Correct Answer is B
Choice A rationale:
Incorrect. Insulin pumps should be removed before bathing or swimming to prevent damage to the device. Water can enter the pump through the infusion set or through the battery compartment, causing it to malfunction. This can lead to inaccurate insulin delivery, which can result in hyperglycemia or hypoglycemia.
Additionally, the adhesive that holds the infusion set in place may not stick well to wet skin, which can increase the risk of the infusion set falling out.
It is important to note that some insulin pumps are now waterproof and can be worn while bathing or swimming. However, it is still important to check the manufacturer's instructions before doing so.
Choice B rationale:
Correct. Even though insulin pumps deliver insulin continuously, people who use them still need to monitor their blood glucose levels regularly. This is because many factors can affect blood glucose levels, such as food intake, exercise, stress, and illness.
Monitoring blood glucose levels allows people to adjust their insulin doses as needed to keep their blood glucose levels within a target range.
Recommended frequency of blood glucose monitoring:
Before meals and snacks Two hours after meals At bedtime
Before and after exercise During times of illness or stress
Whenever they feel symptoms of hypoglycemia or hyperglycemia
Choice C rationale:
Incorrect. People who use insulin pumps still need to count carbohydrates. This is because the amount of insulin that is needed to cover a meal depends on the amount of carbohydrates in the meal.
The insulin pump can be programmed to deliver different amounts of insulin for different meals, snacks, and corrections based on carbohydrate intake. This allows for more precise insulin dosing and better blood glucose control.
Choice D rationale:
Incorrect. Insulin pumps are not designed to help people lose weight. They are designed to help people manage their blood glucose levels.
While some people may lose weight when they start using an insulin pump, this is usually due to improved blood glucose control rather than the pump itself.

Correct Answer is D
Explanation
Choice A rationale:
Adenosine is a medication used to treat supraventricular tachycardia (SVT), a type of rapid heart rhythm that originates in the upper chambers of the heart. It works by slowing the conduction of electrical impulses through the heart's AV node.
In this patient, the heart rate is already slow (42 beats per minute), so adenosine would not be appropriate. It could further slow the heart rate and potentially cause a dangerous drop in blood pressure.
Choice B rationale:
Amiodarone is a medication used to treat a variety of heart rhythm problems, including ventricular tachycardia (VT) and ventricular fibrillation (VF). It works by slowing the conduction of electrical impulses through the heart muscle.
Amiodarone is not typically used as a first-line treatment for bradycardia (slow heart rate). It is usually reserved for more serious or life-threatening arrhythmias.
Choice C rationale:
Magnesium sulfate is a medication used to treat a variety of conditions, including preeclampsia, eclampsia, and torsades de pointes. It can also be used to treat certain types of arrhythmias.
Magnesium sulfate is not typically used as a first-line treatment for bradycardia. It may be used in some cases of bradycardia caused by electrolyte imbalances or certain medications.
Choice D rationale:
Atropine sulfate is a medication that blocks the action of acetylcholine, a neurotransmitter that slows the heart rate. It is the first-line treatment for symptomatic bradycardia.
Atropine works by increasing the heart rate and improving conduction through the AV node. It is a rapid-acting medication that can be given intravenously, intramuscularly, or subcutaneously.
In this patient, atropine sulfate would be the most appropriate medication to increase the heart rate and improve blood pressure.
Correct Answer is D
Explanation
Choice A rationale:
Placing the tablet under the patient's nose is not an effective method of administering aspirin. Aspirin is not absorbed through the nasal mucosa.
This action would not provide any therapeutic benefit to the patient with a suspected myocardial infarction. It could potentially lead to aspiration of the tablet if the patient sneezes or coughs.
Choice B rationale:
Enteric-coated aspirin tablets are designed to dissolve in the intestines, not in the stomach. This delays the absorption of aspirin and its antiplatelet effects.
In a patient with a suspected myocardial infarction, it is crucial to achieve rapid absorption of aspirin to inhibit platelet aggregation and prevent further clot formation.
Therefore, enteric-coated aspirin is not appropriate in this situation.
Choice C rationale:
Chewing the aspirin tablet would indeed speed up its absorption. However, it also increases the risk of gastric irritation and bleeding.
Aspirin can be irritating to the stomach lining, and chewing it can exacerbate this effect.
This is particularly concerning in a patient with a suspected myocardial infarction, who may already be at risk for gastrointestinal bleeding due to decreased blood flow to the stomach.
Choice D rationale:
Giving the aspirin tablet with a small sip of water is the most appropriate action for the nurse to take in this situation. This allows for timely absorption of the aspirin while minimizing the risk of gastric irritation.
The water helps to dissolve the tablet and transport it to the stomach, where it can be absorbed into the bloodstream. It also helps to lubricate the esophagus and reduce the risk of the tablet becoming lodged in the throat.
