A nurse is assisting with the care of a 17-year-old client who is married and needs to undergo an emergency appendectomy. Which of the following individuals should the nurse ask to sign the informed consent form?

A. Respiratory rate: A respiratory rate of 30 breaths per minute indicates significant respiratory distress. Labored breathing combined with crackles and wheezes suggests impaired gas exchange and possible lower respiratory infection requiring urgent intervention.

B. Oxygen saturation level: An oxygen saturation of 89% on room air reflects hypoxemia. Reduced oxygen levels place the client at risk for tissue hypoxia and worsening respiratory failure, making prompt follow-up and oxygen therapy necessary.

C. Chronic health condition: A history of smoking, Parkinson’s disease, and anxiety increases overall health risk but does not explain the acute deterioration. Chronic conditions provide context but are not the immediate priority compared with current unstable findings.

D. Tremors: Hand tremors are consistent with Parkinson’s disease and may also be worsened by anxiety or illness. Tremors alone do not pose an immediate life-threatening risk in this situation.

E. Current level of consciousness: Orientation only to self and failure to follow commands suggest acute changes in mental status. Altered cognition in an older adult with fever and hypoxia may indicate delirium or worsening infection and requires immediate evaluation.

F. Heart rate: A heart rate of 104 beats per minute indicates mild tachycardia, likely related to fever or hypoxia. Although important to monitor, it is less immediately threatening than hypoxemia, tachypnea, and altered mental status.

A. Waste containers are lined with single bags: Using single-lined waste containers is standard practice and does not pose a significant infection risk. Properly contained waste helps maintain cleanliness and reduce exposure to pathogens.

B. Dampened cloths are used for dusting the area: Using dampened cloths prevents dust from becoming airborne and spreading microorganisms. This method reduces the risk of infection and is appropriate for immunocompromised clients.

C. Uncapped sharps are put in a puncture-resistant container: Sharps should always be capped or handled carefully, but placing them directly in a puncture-resistant container is safe and prevents needlestick injuries.

D. Soiled linens are placed on the floor: Placing soiled linens on the floor exposes them to environmental pathogens and increases the risk of cross-contamination. For immunocompromised clients, proper handling and containment of soiled linens are critical to prevent infection.
