A nurse is caring for a child who has cystic fibrosis and is taking dornase alfa. Which of the following actions should the nurse take to evaluate the effectiveness of the medication?

Determine the child's heart rate.

Weigh the child daily.

Auscultate the child's breath sounds.

Monitor the child's 180.

Answer and Explanation

The Correct Answer is C

Choice A reason:

Determining the child's heart rate is important for assessing overall cardiovascular health, but it is not specific to evaluating the effectiveness of dornase alfa.

Choice B reason:

Weighing the child daily is important for monitoring overall nutritional status and fluid balance, but it is not specific to evaluating the effectiveness of dornase alfa.

Choice C reason:

Dornase alfa is a medication used to help clear mucus from the airways in individuals with cystic fibrosis. Therefore, auscultating the child's breath sounds for improved air exchange and reduced adventitious lung sounds is a direct way to evaluate the effectiveness of the medication.

Choice D reason:

Monitoring the child's 180 (assuming this is a typo and referring to heart rate) is important, but it is not specific to evaluating the effectiveness of dornase alfa.

Correct Answer is D

Explanation

Choice A reason:

While an oatmeal bath can provide relief from itching, it is not the first step in treating poison ivy exposure. The immediate priority is to remove the plant oils from the skin.

Choice B reason:

Administering an oral corticosteroid may be indicated for severe cases of poison ivy, but it is not the initial step. Removing the plant oils from the skin is the first priority.

Choice C reason:

Applying calamine lotion can help soothe itching, but it is not the first action to take. The priority is to remove any remaining plant oils from the skin.

Choice D reason:

The first action the nurse should take is to remove any remaining plant oils from the skin by flushing the affected area with cold, running water. This helps to prevent further absorption of the irritant.

A. Increased urinary output B. Tachycardia C. Bounding peripheral pulses D. Increased blood pressure

Correct Answer is B

Explanation

Choice A reason:

Increased urinary output is not typically associated with heart failure. In fact, heart failure often leads to decreased urine output due to decreased cardiac output.

Choice B reason:

Tachycardia (rapid heart rate) is a common manifestation of heart failure in infants. The heart compensates for decreased cardiac output by beating faster.

Choice C reason:

Bounding peripheral pulses are not typically associated with heart failure. In fact, weak peripheral pulses may be a sign of decreased cardiac output.

Choice D reason:

Increased blood pressure is not typically associated with heart failure in infants. Instead, infants with heart failure may have low or normal blood pressure.
