A nurse in a provider's office is assessing a client who reports dyspnea and fatigue. Physical assessment reveals tachycardia and weak peripheral pulses. The nurse should recognize these findings as manifestations of which of the following conditions?

Asthma

Aortic valve regurgitation

Heart failure

Aortic stenosis

Answer and Explanation

The Correct Answer is C

A. Asthma typically presents with wheezing, shortness of breath, and chest tightness. While dyspnea is a symptom, tachycardia and weak peripheral pulses are not characteristic findings associated with asthma.
B. Aortic valve regurgitation may cause dyspnea and fatigue, but it is more commonly associated with bounding pulses and diastolic murmur rather than weak peripheral pulses.
C. Heart failure is characterized by symptoms such as dyspnea, fatigue, tachycardia, and weak peripheral pulses due to reduced cardiac output and poor perfusion to the extremities. The nurse should recognize these signs as indicative of heart failure.
D. Aortic stenosis can lead to symptoms like dyspnea and fatigue; however, it typically presents with a triad of symptoms including exertional dyspnea, angina, and syncope, rather than weak peripheral pulses.

Correct Answer is ["24"]

Explanation

To calculate the infusion rate, use the formula:

(rate in mL/hr) = (desired dose in units/hr) / (available dose in units/mL)

In this case, the desired dose is 1,200 units/hr and the available dose is 25,000 units / 500 mL = 50 units/mL. Therefore,

(rate in mL/hr) = (1,200 units/hr) / (50 units/mL) = 24 mL/hr

Round the answer to the nearest tenth/whole number and use a leading zero if it applies. Do not use a trailing zero because it could be misread as a decimal point. Therefore, the nurse should set the IV pump to deliver 24 mL/hr.

A. Avoid taking the medication prior to exercising. B. Stop taking the medication and notify your provider if you develop a headache. C. Place the tablet under your tongue, and then take a small sip of water. D. The medication can take up to 15 minutes to take eﬀect.
