Correct Answer: B

Rationale: The change from low-pitched wheezes to high-pitched wheezes indicates a shift from larger to smaller airway obstruction, suggesting increased narrowing of the airways. This change signifies a progression or worsening of the airway obstruction. The absence of evidence of secretions does not support the need for suctioning. Hyperventilation is characterized by rapid and deep breathing, which is not indicated by the information provided in the question.

Correct Answer: C

Rationale: The correct answer is that nonsteroidal anti-inflammatory drugs are the first choice in treatment for juvenile idiopathic arthritis (formerly known as juvenile rheumatoid arthritis). NSAIDs are important as a first-line treatment and typically require 3-4 weeks for the therapeutic anti-inflammatory effects to be realized. Choice A is incorrect as early treatment can improve outcomes and prevent joint deformities. Choice B is incorrect as juvenile idiopathic arthritis does not necessarily progress to adult rheumatoid arthritis. Choice D is incorrect as physical activity should be encouraged in children with arthritis to maintain joint mobility and overall health.

Correct Answer: C

Rationale: Placing the patient on a pressure-relieving mattress is crucial to decrease the risk of skin breakdown, especially with significant edema and ascites. Adequate dietary protein intake is essential in patients with ascites to improve oncotic pressure and prevent malnutrition. Repositioning the patient every 4 hours alone may not be sufficient to prevent skin breakdown, especially in areas prone to pressure ulcers. Performing passive range of motion exercises is important for maintaining joint mobility but does not directly address the risk of skin breakdown associated with prolonged pressure on vulnerable areas.

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: 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.
