A nurse is teaching a client about smoking cessation. Which of the following client statements should the nurse identify as an understanding of the teaching?

A. Urinary output of 100 mL in 4 hr: This indicates a urine output of 25 mL/hr, which is slightly below the expected minimum of 30 mL/hr for adequate renal perfusion. While important to monitor, it is not immediately life-threatening compared to respiratory compromise.

B. Coughing frothy, pink secretions: Frothy, pink sputum can indicate pulmonary edema, a potentially life-threatening condition that requires immediate assessment and intervention to prevent respiratory failure. Airway and oxygenation take priority in the postoperative client.

C. Emesis of 110 mL of thick, yellow fluid: Postoperative vomiting is concerning for nausea or potential infection, but it is not immediately life-threatening. Management includes antiemetics and monitoring for dehydration.

D. Red drainage on the dressing: Some postoperative bleeding is expected, especially in the first few hours after surgery. While the nurse should monitor for excessive hemorrhage, small amounts of red drainage are less urgent than signs of pulmonary compromise.

A. Wear a mask while in the room with the toddler: Varicella (chickenpox) is transmitted via airborne and contact routes. Standard precautions include contact and airborne precautions, so an N95 or fitted mask is required rather than a simple mask.

B. Wipe the stethoscope with an alcohol-based gel after use: Cleaning equipment that comes into contact with the client helps prevent the spread of infection. Alcohol-based disinfectants effectively reduce transmission of varicella from shared medical equipment.

C. Place the toddler in a room with positive-pressure airflow: Positive-pressure rooms are used for immunocompromised clients to prevent pathogens from entering. Airborne precautions for varicella require a negative-pressure room to prevent spreading the virus to others.

D. Schedule the toddler for private time in the playroom: Allowing a child with varicella in communal areas risks spreading the virus to susceptible children. The toddler should remain in isolation until lesions crust over.
