Correct Answer: A

Rationale: The correct answer is A: 'Pupils reactive to accommodation.' When pupils constrict as the client changes focus from a far object to a near one, it indicates a normal response known as accommodation. This physiological process allows the eyes to adjust their focus, and it is a healthy finding. Choice B is incorrect because nystagmus is an involuntary eye movement, not related to the change in focus. Choice C is irrelevant to the scenario and does not describe the observed finding. Choice D refers to pupillary constriction in response to light, not accommodation to changes in focus.

Correct Answer: D

Rationale: A water-soluble lubricant is safe to use in conjunction with oxygen therapy, unlike petroleum jelly which is flammable.

Correct Answer: C

Rationale: The correct answer is C. The use of accessory muscles indicates increased work of breathing and can signal respiratory failure in a client with COPD. This finding requires immediate intervention to prevent further respiratory compromise. Oxygen saturation of 90% indicates some oxygenation impairment but may not necessitate immediate intervention. A respiratory rate of 24 breaths per minute is slightly elevated but does not indicate immediate respiratory distress. Inspiratory crackles may be present in pneumonia but do not require immediate intervention compared to the increased work of breathing indicated by the use of accessory muscles.

Correct Answer: D

Rationale: The correct answer is D. A client who had an abdominal-perineal resection 2 days ago with no drainage on the dressing but is presenting with fever and chills requires immediate attention. This presentation raises concerns for peritonitis, a serious complication that necessitates prompt assessment and intervention to prevent further complications. Choices A, B, and C do not indicate an immediate risk for a life-threatening condition like peritonitis, making them lower priority compared to choice D.

Correct Answer: C

Rationale: Administering insulin is the most important intervention in managing diabetic ketoacidosis. In DKA, there is a lack of insulin leading to hyperglycemia and ketosis. Insulin administration helps to reduce blood glucose levels and correct metabolic acidosis, which are crucial in treating DKA. Administering intravenous fluids helps with dehydration, monitoring urine output is important to assess renal function, but the priority is addressing the underlying cause of DKA by administering insulin. Administering 50% dextrose IV push is incorrect as it would further elevate blood glucose levels, which is contraindicated in DKA.
