A nursing student is preforming a head-to-toe assessment on his patient with a history of mitral regurgitation. Instead of hearing normal heart sounds the student hears a murmur.

Which of the following best describes the sound of a heart murmur?

A.

Lub-dub sounds

B.

Gentle blowing or swooshing noise

C.

Scratchy, leathery heart noise

D.

Abrupt, high-pitched snapping noise

Answer and Explanation

The Correct Answer is B

A. Lub-dub sounds:

This describes the normal heart sounds, with the "lub" representing the closing of the mitral and tricuspid valves (S1) and the "dub" representing the closing of the aortic and pulmonic valves (S2). This is the typical and expected sound of a healthy heart.

B. Gentle blowing or swooshing noise:

This describes the characteristic sound of a heart murmur. Murmurs are abnormal sounds caused by turbulent blood flow, and they are often described as a gentle blowing or swooshing noise heard between the normal heart sounds.

C. Scratchy, leathery heart noise:

This description is not typical for heart sounds or murmurs. Heart sounds are usually described in terms of tones, clicks, or swooshing rather than scratchy or leathery.

D. Abrupt, high-pitched snapping noise:

This description is not typical for heart sounds or murmurs. Heart murmurs are generally characterized by a more continuous, blowing, or swooshing quality, rather than abrupt, high-pitched snapping noises.

Correct Answer is ["45"]

Explanation

To calculate the amount of potassium chloride (K-Dur) solution to administer, we need to use the following formula:

mL to administer = ordered dose (mEq) / available dose (mEq/mL) x mL

Plugging in the values from the question, we get:

mL to administer = 60 mEq / (20 mEq / 15 mL) x 15 mL

Simplifying the equation, we get:

mL to administer = 60 mEq x 15 mL / 20 mEq

mL to administer = 45 mL

Therefore, the nurse should administer 45 mL of potassium chloride (K-Dur) solution to the patient.

Correct Answer is A

Explanation

A. Take the blood pressure:

Assessing blood pressure is a critical initial step when a patient is experiencing dyspnea. It helps provide information about the patient's overall cardiovascular status, which is essential in determining the severity of the dyspnea and guiding subsequent interventions.

B. Remove the pillow from under the patient’s head:

Removing the pillow may be a relevant intervention if the patient is in a position that could be contributing to respiratory distress. However, the priority is to first assess vital signs, particularly blood pressure, to gather information about the patient's cardiovascular status.

C. Elevate the foot of the bed:

Elevating the foot of the bed may be a consideration if the dyspnea is related to conditions such as heart failure, where raising the legs can help reduce venous return and decrease the workload on the heart. However, the initial priority is to assess blood pressure to guide appropriate interventions.

D. Elevate the head of the bed:

Elevating the head of the bed may be beneficial for patients with respiratory distress to improve ventilation and oxygenation. While this intervention may be appropriate, the first action should be to assess vital signs, particularly blood pressure, to gain an overall understanding of the patient's condition.
