Which finding in a postoperative patient requires immediate intervention by the nurse?

Correct Answer: D

Rationale: In a postoperative patient, an oxygen saturation level of 88% on room air indicates a significant drop below the normal range, suggesting potential respiratory distress. This finding requires immediate intervention by the nurse to ensure the patient receives adequate oxygenation. A heart rate of 88 beats per minute is within the normal range, making it a less concerning finding. A blood pressure of 130/80 mmHg falls within the normal range for blood pressure and does not require immediate intervention. Crackles heard in the lung bases may indicate fluid accumulation but may not always require immediate intervention unless accompanied by other concerning signs or symptoms.

Correct Answer: B

Rationale: The most important nursing intervention when caring for a patient with a wound is to clean the wound with normal saline. This is crucial for preventing infection and promoting healing. Applying an occlusive dressing (Choice A) can be important but should come after cleaning the wound. Administering antibiotics (Choice C) is not the first-line intervention for all wounds and should be based on the healthcare provider's prescription. Reassessing the wound (Choice D) is essential but not the most important initial intervention.

Correct Answer: B

Rationale: The most important information to provide to a patient with heart failure regarding fluid restrictions is to provide them with a fluid restriction plan. This plan helps the patient manage their fluid intake effectively, which is crucial in preventing complications associated with heart failure. Monitoring weight daily can be a part of the plan but is not the most important. Instructing the patient to avoid salty foods is beneficial but not as crucial as having a structured fluid restriction plan. Encouraging the patient to increase fluid intake would be counterproductive and potentially harmful in a patient with heart failure.

Correct Answer: B

Rationale: Emptying the colostomy bag when it is half full is the most important nursing action when caring for a patient with a colostomy. This practice helps prevent leakage, reduces the risk of skin irritation, and promotes patient comfort. Monitoring for signs of infection (Choice A) is essential but not as crucial as maintaining proper colostomy care. Encouraging the patient to eat smaller, more frequent meals (Choice C) can be beneficial for colostomy patients but is not as critical as ensuring timely emptying of the colostomy bag. Applying a skin barrier to prevent irritation (Choice D) is important, but ensuring timely emptying of the colostomy bag takes precedence in preventing complications associated with a colostomy.

Correct Answer: A

Rationale: The correct answer is to ensure the catheter tubing is not kinked. This is the priority action because a kinked tubing can obstruct urine flow, leading to discomfort and potential complications. It is essential to troubleshoot the current catheter first before considering other interventions. Irrigating the catheter (Choice B) may not address the underlying issue of kinking. Changing the catheter to a smaller size (Choice C) or removing and replacing it with a new one (Choice D) should only be considered if ensuring the tubing is unkinked does not resolve the discomfort.
