Correct Answer is {"dropdown-group-1":"C","dropdown-group-2":"B"}
Explanation
The priority action the nurse should perform is increase oxygen flow rateas evidenced by the client’s oxygen saturation.
Rationale:
The client’s oxygen saturation has dropped to 90% on 1 L/min oxygen via nasal cannula, which is below the expected range of 95–100% for adequate oxygenation. Hypoxemia is an immediate threat and requires prompt intervention to prevent tissue hypoxia. Increasing the oxygen flow rate is the most direct action to improve oxygenation. Repeating arterial blood gases is useful for monitoring but does not immediately correct hypoxemia. Administering acetaminophen may address the fever but does not correct the priority problem of low oxygen saturation.
Correct Answer is B
Explanation
A. Percussion is performed before palpation but after auscultation to prevent altering bowel sounds.
B. Palpation is the final step in abdominal assessment because it can stimulate bowel activity, changing the characteristics of bowel sounds. The correct sequence is: Inspection → Auscultation → Percussion → Palpation.
C. Auscultation occurs before percussion and palpation to assess bowel sounds accurately without interference.
D. Inspection is always performed first to observe for contour, symmetry, scars, or distention before any manipulation of the abdomen.
