Several hours after returning from surgery, the nurse tells the patient that she is ordered to be ambulated. The patient asks, "Why?" Which of the following complications would the nurse correctly explain can be prevented by early postoperative ambulation?

Correct Answer: C

Rationale: Early postoperative ambulation is important for preventing complications such as pneumonia. When a patient remains immobile for an extended period after surgery, they are at an increased risk of developing pneumonia due to decreased lung expansion and secretions pooling in the lungs. Ambulation helps improve lung function, promote better oxygenation, and prevent respiratory complications like pneumonia. In contrast, increased peristalsis helps prevent constipation, coughing helps prevent respiratory complications as well, and wound healing is not directly related to the need for early postoperative ambulation.

Correct Answer: C

Rationale: Thrombophlebitis commonly affects the veins deep in the lower extremities, such as the femoral vein or the iliac vein. This condition involves the formation of a blood clot (thrombus) in a vein, usually due to inflammation or injury to the vein wall. The lower extremities are more prone to thrombophlebitis because of factors like gravity, reduced blood flow in the veins of the legs, and prolonged sitting or immobility which can increase the risk of blood clot formation. Thrombophlebitis in the lower extremities can potentially lead to serious complications, such as pulmonary embolism if a clot breaks loose and travels to the lungs.

Correct Answer: D

Rationale: During the acute phase of treatment with IV calcium gluconate for hypocalcemia in a newborn, it is essential to closely monitor the newborn's level of consciousness. Hypocalcemia can lead to central nervous system changes, such as irritability, jitteriness, and seizures. By awakening the newborn periodically to assess their level of consciousness, the nurse can promptly identify any signs of worsening central nervous system involvement and take appropriate action. This intervention ensures timely detection of any neurological complications and allows for timely intervention to prevent serious consequences. The other options do not address the importance of monitoring for central nervous system changes during the acute phase of treatment for hypocalcemia.

Correct Answer: A

Rationale: Surgical resection is the definitive treatment for cystic hygroma.

Correct Answer: C

Rationale: Toddlers typically engage in parallel play rather than cooperative play.
