A client is being admitted to the surgical unit from the PACU following a cholecystectomy. Which of the following assessments is the nurse's priority?
- A. Bowel sounds
- B. Surgical dressing
- C. Temperature
- D. Oxygen saturation
Correct Answer: D
Rationale: The correct answer is D: Oxygen saturation. The priority assessment after a cholecystectomy is monitoring the client's oxygen saturation to ensure adequate oxygenation post-surgery. Decreased oxygen saturation can indicate respiratory distress, which requires immediate intervention. Bowel sounds (A) are important but not the priority post-cholecystectomy. Surgical dressing (B) should be assessed, but it is not as critical as monitoring oxygen saturation. Temperature (C) is also important, but ensuring oxygenation takes precedence in the immediate postoperative period.
The nurse identifies the presence of age-associated memory impairment in the older adult who states
- A. I just can't seem to remember the name of my granddaughter.
- B. I make out lists to help me remember what I need to do but I can't seem to use them.
- C. I forgot that I went to the grocery store this morning and didn't realize it until I went again this afternoon.
- D. I forget movie stars' names more often now but I can remember them later after the conversation is off.
Correct Answer: C
Rationale: Age-associated memory impairment typically involves short-term memory lapses rather than complete forgetting. Forgetting actions like visiting the grocery store earlier in the day aligns with this type of impairment.
While caring for a client receiving positive-pressure mechanical ventilation, which intervention should the nurse NOT implement to prevent complications?
- A. Elevate the head of the bed to at least 30°.
- B. Verify the prescribed ventilator settings daily.
- C. Administer pantoprazole as prescribed.
- D. Reposition the endotracheal tube to the opposite side of the mouth daily.
Correct Answer: D
Rationale: The correct answer is D. Repositioning the endotracheal tube to the opposite side of the mouth daily is not necessary and could potentially lead to complications such as accidental extubation or damage to the airway. A: Elevating the head of the bed helps prevent aspiration. B: Verifying ventilator settings daily ensures proper functioning. C: Administering pantoprazole helps prevent stress ulcers. In summary, D is incorrect because it is unnecessary and poses risks, while A, B, and C are important interventions to prevent complications associated with positive-pressure mechanical ventilation.
