The nurse notes vigorous bubbling in the water-seal chamber of a chest-drainage system. Which of the following actions should the nurse take to correct the bubbling?

Correct Answer: A

Rationale: The nurse should examine the entire system and tubing for air leaks when observing vigorous bubbling in the water-seal chamber of a chest-drainage system. Vigorous bubbling indicates that there is air escaping from the system, which can lead to suboptimal drainage and potential complications. By identifying and correcting any air leaks, the nurse can ensure the chest-drainage system functions effectively, allowing for proper drainage and the prevention of complications such as pneumothorax. Lowering the level of suction or asking the patient to cough forcefully would not address the underlying issue of air leaks and may not resolve the problem effectively.

Correct Answer: C

Rationale: Frequent oral care is important for overall oral health and cleanliness, but it will not directly help correct the patient's fluid imbalance. The patient's condition likely requires direct fluid replacement to address the fluid loss and restore balance. A, B, and D are focused on fluid replacement strategies which are more crucial in correcting the patient's condition. Offering a large amount of oral fluid intake to replace lost fluids, giving enteral or parenteral fluid, and giving small volumes of fluid at frequent intervals are all appropriate measures that can help correct the patient's condition by addressing the underlying fluid imbalance.

Correct Answer: A

Rationale: Referral to an obstetrician is necessary for proper evaluation and management.

Correct Answer: A

Rationale: Referring the child for immediate medical evaluation is the most appropriate action in this scenario. The symptoms described, including hyperextension of the head (opisthotonos) with pain on flexion, are concerning for meningitis, a serious infection that can rapidly progress and lead to serious complications if not treated promptly. Seeking immediate medical intervention is crucial to assess and manage the child's condition effectively. Continuing with the assessment or asking about a neck injury is not recommended as the priority is to address the potential medical emergency. Recording the "head lag" without taking immediate action could delay necessary medical treatment.

Correct Answer: D

Rationale: Recombinant urate oxidase (rasburicase) effectively lowers uric acid levels in cases of tumor lysis syndrome.
