When entering a client's room to administer an 0900 IV antibiotic, the nurse finds that the client is engaged in sexual activity with a visitor. Which action should the nurse implement?

A. Humidifier bottle

Rationale: A humidifier bottle is often used with oxygen therapy to add moisture to the oxygen, preventing dryness of the nasal passages and throat. It is important for patient comfort, especially when oxygen is administered at higher flow rates for prolonged periods.

B. Lamb's wool

Rationale: Lamb's wool is not needed for starting oxygen therapy. It is typically used to provide padding and comfort in other situations, such as preventing pressure sores, but it has no role in the administration of oxygen.

C. Flowmeter

Rationale: A flowmeter is necessary to regulate the flow rate of oxygen. It ensures that the client receives the prescribed amount of oxygen (3 L/minute in this case), making it an essential component for administering oxygen therapy.

D. Tape

Rationale: Tape is not required for administering oxygen via a nasal cannula. It might be used to secure tubing in other contexts, but it is not specifically needed for starting oxygen therapy. The nasal cannula usually stays in place without the need for tape.

E. Suction cannister

Rationale: A suction canister is used in suctioning procedures to collect secretions and is not needed for starting oxygen therapy. It is relevant for managing airway secretions but unrelated to the administration of oxygen.

F. Nasal cannula

Rationale: A nasal cannula is the device through which oxygen is delivered to the client. It is specifically mentioned in the order and is essential for administering the oxygen.

G. Sterile water

Rationale: Sterile water is used to fill the humidifier bottle to provide humidified oxygen. This helps to prevent the drying effects of oxygen therapy on the mucous membranes, enhancing patient comfort.

A. Initiating teaching for client care after discharge is incorrect. Teaching, especially initial or comprehensive education, is within the scope of practice of a registered nurse (RN), not a practical nurse (PN).
B. Using bladder ultrasound to detect urinary retention is correct. This is a task within the scope of practice for a PN, as it involves data collection and does not require independent clinical judgment.
C. Completing comprehensive assessments is incorrect. Comprehensive assessments require critical thinking and are the responsibility of the RN. PNs may collect data but do not perform initial comprehensive assessments.
D. Beginning initial sterile wound care for surgical clients is incorrect. The RN should perform the first sterile dressing change postoperatively to assess the wound properly. The PN may perform subsequent dressing changes per facility policy.
