A client has just been diagnosed with active tuberculosis. Which of the following nursing interventions should the nurse perform to prevent transmission to others?

Correct Answer: D

Rationale: A client diagnosed with active tuberculosis should be placed in isolation in a negative-pressure room to prevent transmission of infection to others. Placing the client in a negative-pressure room ensures that air is exhausted to the outside and received from surrounding areas, preventing tuberculin particles from traveling through the ventilation system and infecting others. Initiating standard precautions, as mentioned in choice C, is essential for infection control but is not specific to preventing transmission in the case of tuberculosis. Beginning drug therapy within 72 hours of diagnosis, as in choice A, is crucial for the treatment of tuberculosis but does not directly address preventing transmission. Placing the client in a positive-pressure room, as in choice B, is incorrect as positive-pressure rooms are used for clients with compromised immune systems to prevent outside pathogens from entering the room, which is not suitable for a client with active tuberculosis.

Correct Answer: B

Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.

Correct Answer: C

Rationale: In the post-anesthesia care unit, clients may experience shivering or chills due to a drop in body temperature after surgery. Meperidine (Demerol) can be prescribed to alleviate shivering in cold clients. The prone position (lying face down) and deep breathing exercises are not interventions specifically indicated for addressing shivering due to low body temperature. Therefore, administering meperidine as ordered is the most appropriate action to manage the client's shivering in this scenario.

Correct Answer: C

Rationale: A Jackson-Pratt drain is a type of active wound drain that may be placed following a surgical procedure. This drain actively draws excess blood and fluid out of the wound. If clots develop within the tubing, the nurse should strip the tubing by milking it in a direction away from the client. This action helps to ensure the drain remains patent and effective. Option A is incorrect because the tubing should be milked away from the client, not towards. Option B is incorrect as the drain should be emptied based on the healthcare provider's orders, not at a fixed volume. Option D is incorrect because the level of the drain should be below the level of the incision to allow drainage by gravity.

Correct Answer: A

Rationale: Excess secretions from the tracheostomy tube can collect near the stomal opening and cause skin breakdown. Management of secretions through regular suctioning will keep the area clean and dry, minimizing skin irritation. Choice B, cleansing the site daily with povidone-iodine and water, is incorrect as it may lead to skin irritation due to the harshness of povidone-iodine. Choice C, avoiding tube ties to secure the tube, is also incorrect as securing the tube is essential for stability. Choice D, 'None of the above,' is incorrect as managing secretions through suctioning is crucial in preventing skin irritation.
