Correct Answer: C

Rationale: To completely remove ointment, especially zinc oxide, mineral oil should be used. Mineral oil helps in gently breaking down and lifting the ointment without causing irritation. Mild soap and water (Choice A) may not be effective in completely removing zinc oxide. A cotton ball (Choice B) may not provide the necessary lubrication to aid in the removal process. Alcohol swabs (Choice D) can be harsh on the skin and are not recommended for this purpose.

Correct Answer: B

Rationale: The correct answer is B: Prepare for cessation of the anesthesia and the surgical procedure. Malignant hyperthermia is a severe reaction to certain medications used during general anesthesia. The immediate intervention to manage malignant hyperthermia is to stop the triggering agents, which include anesthesia and surgery. Ensuring patency of an indwelling catheter and measuring intake and output, obtaining specimens of ABGs and serum electrolytes, and initiating cooling measures are important interventions but should follow the immediate action of stopping the anesthesia and surgery to address the life-threatening condition of malignant hyperthermia.

Correct Answer: B

Rationale: The correct answer is to notify the healthcare provider immediately (Choice B). Sudden severe eye pain and blurred vision can indicate acute angle-closure glaucoma, which is a medical emergency requiring prompt evaluation and treatment to prevent vision loss. Administering pain medication (Choice A) may provide temporary relief but does not address the underlying cause. Placing an eye patch (Choice C) may not be appropriate without knowing the exact cause of the symptoms. Preparing for a CT scan (Choice D) is not the immediate priority in this situation where urgent medical attention is needed.

Correct Answer: D

Rationale: The correct answer is D. Tachycardia and dyspnea are signs of fluid overload, which is a potential complication of IV fluid therapy. Choices A, B, and C are not directly related to fluid overload and are not typical signs of complications associated with the IV fluid therapy being administered.

Correct Answer: C

Rationale: It is crucial for the nurse to evaluate the application of the splint to the left leg in a client with diminished distal pulses. This assessment helps ensure that the splint is not causing any compromise to circulation. Verifying pulses and monitoring for leg conditions are important interventions but do not directly address the issue with the splint application in this scenario, making them less relevant.
