Correct Answer: B

Rationale: At 3 months, infants typically develop the ability to lift their heads 45 degrees in prone, follow objects with their eyes, smile responsively, and make cooing sounds. They are not yet able to sit independently.

Correct Answer: B

Rationale: Elevating the head of the bed at a 10 to 20-degree angle helps to increase intrathoracic pressure. This increase in pressure can aid in promoting cerebrospinal fluid drainage and reducing intracranial pressure. It is important to maintain the correct angle to achieve the desired effect and avoid potential complications. If Tiffany's parents mention this as the reason for elevating the bed, Nurse Charlie should reexplain the purpose to ensure they understand the intended outcome.

Rationale: Providing comfort items and avoiding suction items helps reduce distress and supports healing.

Correct Answer: C

Rationale: When a client undergoes treatment for a malignant tumor requiring a urinary diversion procedure, such as a urostomy, it is crucial for nurses to closely monitor for any signs of leakage of urine or stool from the anastomosis site. This is important because it can indicate complications such as infection, poor wound healing, or a breakdown in the surgical site. Detecting and addressing leakage promptly can help prevent further complications and ensure the client's recovery progresses smoothly. While the other options may be important aspects of nursing care, observing for leakage of urine or stool from the anastomosis is the most critical factor in managing clients undergoing treatment for a malignant tumor affecting the urinary system.
