A nurse auscultates heart sounds. When the nurse hears S2, which valves is the nurse hearing close?

A. Tell the client to blow his/her nose gently before the instillation of the drops. Blowing the nose clears the nasal passages, allowing the medication to reach the mucosa effectively.

B. Assist the client to a side-lying position. The correct position is head tilted backward (supine with neck hyperextended) or head tilted slightly to the side to ensure proper absorption. A side-lying position is not appropriate for nasal drops.

C. Hold the dropper 2 cm (1 inch) above the nares. The dropper should be placed just inside the nostril without touching it to prevent contamination. Holding it too high may cause the drops to miss the nasal mucosa.

D. Instruct the client to stay in the same position for 2 minutes. Remaining in position for at least 5 minutes allows the medication to be absorbed without draining out of the nasal cavity.

A. Muscular strength assessment: While muscular strength is important for overall mobility and health, it is not a key factor in wound healing. Wound healing is primarily influenced by oxygenation, perfusion, and nutrition.

B. Sensation assessment: While sensation is important in patients with conditions like diabetes (due to the risk of neuropathy and unnoticed wounds), it is not the most relevant assessment for determining wound healing.

C. Sleep assessment: Adequate rest is beneficial for healing, but sleep assessment is not the primary factor that determines wound healing. Other physiological factors play a greater role.

D. Pulse oximetry assessment: Oxygenation is a critical factor in wound healing. Low oxygen levels impair tissue repair, increase infection risk, and slow cell regeneration. Pulse oximetry assesses the oxygen levels in the blood, making it the most relevant assessment for wound healing.
