A nurse experiences difficulty auscultating the heart sounds of a client. What should the nurse do to assure they are able to auscultate the heart sounds?

Place the diaphragm against the client's clothing and angle biannuals toward nose.

Ensure that the ear pieces are loose and comfortable in ears.

Ask the client to hold their breath during auscultation.

Eliminate distracting noises from the environment and ensure a snug fit with the ear pieces.

Answer and Explanation

The Correct Answer is D

A. Placing the diaphragm against clothing can interfere with sound transmission. The stethoscope should be placed directly on the skin.
B. Earpieces should fit snugly in the ears to optimize sound conduction, rather than being loose.
C. Asking the client to hold their breath is not a standard technique for improving heart sound auscultation; it is more useful for breath sounds or murmurs.
D. "Eliminate distracting noises from the environment and ensure a snug fit with the ear pieces" is correct because background noise can interfere with auscultation, and a proper fit enhances sound transmission.

Correct Answer is A

Explanation

A. Oral mucosa is correct. Central cyanosis occurs when oxygen saturation is significantly reduced and is best assessed in areas with rich vascular supply, such as the oral mucosa, lips, and tongue.
B. Palms are incorrect because peripheral cyanosis (often due to cold exposure or poor circulation) can cause blue-tinged extremities, but this does not indicate central cyanosis.
C. Sclera is incorrect because cyanosis does not affect the sclera; however, jaundice does.
D. Nail beds are incorrect because, like the palms, they are more indicative of peripheral cyanosis, which can result from localized poor perfusion rather than central oxygenation problems.

A. Macule B. Nodule C. Pustule D. Papule

Correct Answer is D

Explanation

A. A macule is a flat, non-palpable skin lesion. The described lesion is raised, making macule incorrect.
B. A nodule is a deeper, larger, and firmer lesion (>0.5 cm in diameter). The lesion described is too small to be classified as a nodule.
C. A pustule is a pus-filled lesion. The description does not mention purulent content, ruling out pustule.
D. A papule is correct. A papule is a small, raised, solid lesion that is <1 cm in diameter, which fits the description of the bump on the boy’s neck.
