active and passive cigarette smoke

What assessments would a nurse make when auscultating the lungs?

air flow through respiratory passages

apnea

A client has edema of the feet and ankles, along with crackles in the lower lobes and a frothy, productive cough. The client is suffering from:

congestive heart failure.

The nurse auscultates a client with soft, high-pitched popping breath sounds on inspiration. The nurse documents the breath sounds heard as

crackles.

nail polish thickness of nails acrylic nails peripheral vascular disease

While examining a client, the nurse palpates the client's chest and back. What would the nurse expect to identify with this technique?

A client taking opioids for cancer pain

A nurse is admitting a 6-year-old child after a tonsillectomy to the surgical unit. The nurse obtains the client's weight and places electrocardiogram (EKG) leads on the chest and a pulse oximeter on the left finger. The client's heart rate reads 100 bpm and the pulse oximeter reads 99%. These readings best indicate:
