Correct Answer: C

Rationale: Severe nausea and vomiting with a large volume of vomitus can indicate a serious underlying issue such as gastrointestinal obstruction or other medical emergencies. In this situation, it is crucial for the nurse to notify the physician immediately so that further assessment and appropriate management can be initiated promptly. Delay in seeking medical help can lead to complications and worsen the patient's condition. It is important to act quickly and involve the physician in situations where the patient's health may be at risk.

Correct Answer: A

Rationale: When a patient is prescribed with an angiotensin-converting enzyme (ACE) inhibitor for managing hypertension, the nurse should monitor closely for signs of hyperkalemia. ACE inhibitors can affect the renin-angiotensin-aldosterone system, leading to decreased aldosterone secretion and impaired potassium excretion by the kidneys. As a result, potassium levels in the blood may increase, leading to hyperkalemia.

Correct Answer: B

Rationale: The priority nursing diagnosis for a patient undergoing surgery (closure of the sac) would be risk for infection. This is because surgical procedures increase the risk of infection due to the breach in the skin and introduction of microorganisms. Infection can lead to serious complications, delay healing, and prolong recovery time. Therefore, prevention, early detection, and prompt treatment of infections are essential in the perioperative period to ensure the best possible outcomes for the patient.

Correct Answer: A

Rationale: Administering a stool softener as ordered is the most appropriate nursing intervention for a postpartum client experiencing severe perineal pain and difficulty passing stools following a vaginal delivery. Stool softeners help to soften the stool, making it easier for the client to pass without straining, which can exacerbate perineal pain. It is important to follow the healthcare provider's orders when administering medications to ensure proper dosing and effectiveness. Encouraging the client to refrain from defecation may lead to constipation and worsen the situation. Applying ice packs to the perineum can provide temporary pain relief, but addressing the underlying issue of constipation with a stool softener is more effective in the long term. Providing education on proper perineal hygiene is important for overall postpartum care, but addressing the immediate issue of constipation with a stool softener takes precedence in this scenario.

Correct Answer: D

Rationale: The correct action to prioritize during the initial assessment when preparing to assist with a cardiopulmonary resuscitation (CPR) procedure for a patient in cardiac arrest is to assess the patient's airway, breathing, and circulation (ABCs). This involves quickly checking the patient's airway for any obstructions, assessing their breathing for signs of breathing difficulties or absence of breathing, and evaluating their circulation by checking for a pulse. This step is crucial in determining the need for immediate intervention, such as clearing the airway, providing rescue breaths, or initiating chest compressions. By prioritizing the assessment of the ABCs, the nurse can promptly identify and address life-threatening issues to improve the patient's chances of survival during a cardiac arrest situation.
