A nurse is assisting with the care of a postoperative client who has developed malignant hyperthermia. Which of the following actions should the nurse take?
Administer meperidine IM.
Instill a warm enema solution.
Apply a cooling blanket.
Ventilate client with 50% oxygen.
The Correct Answer is C
Choice A Reason:
Administer meperidine IM is incorrect. Reason why it's not the answer: Meperidine (Demerol) is not recommended in cases of malignant hyperthermia. It can potentially exacerbate the situation by further increasing muscle rigidity and potentially contributing to the hypermetabolic state. Meperidine can trigger additional release of calcium from the sarcoplasmic reticulum in muscles, worsening the symptoms.
Choice B Reason:
Instill a warm enema solution is incorrect. Reason why it's not the answer: Introducing warm solutions can exacerbate the client's condition by further increasing body temperature. Malignant hyperthermia is characterized by a dangerous increase in body temperature, and adding heat through an enema would only make the situation worse.
Choice C Reason:
Applying a cooling blanket is recommendable. Reason why it's the answer: A cooling blanket is a recommended intervention for managing malignant hyperthermia. Lowering the body temperature is crucial in preventing further complications associated with the high fever. Cooling blankets help dissipate heat from the body, aiding in rapidly reducing the dangerously elevated temperature associated with malignant hyperthermia.
Choice D Reason:
Ventilate client with 50% oxygen is incorrect. Reason why it's not the answer: While providing oxygen support might be necessary as part of managing the overall condition, ventilating with 50% oxygen specifically may not directly address the core issue of rapidly cooling the body during a malignant hyperthermia crisis. Ventilation may be required, but the immediate concern is to cool the body to prevent complications arising from the elevated body temperature.

Correct Answer is ["1000"]
Explanation
To lose 0.9 kg (2 lb) of body fat per week, the client needs to create a weekly caloric deficit of 7000 calories (3500 x 2).
This means that he needs to reduce his daily caloric intake by 1000 calories (7000 / 7).
The nurse should instruct the client to calculate his current daily caloric intake and then subtract 1000 calories from that amount. The nurse should also advise the client to eat a balanced diet and exercise regularly to achieve his weight loss goal.
Correct Answer is D
Explanation
Choice A Reason:
Encouraging three large meals daily might not be feasible for someone experiencing malnutrition and decreased appetite. Smaller, more frequent meals or snacks throughout the day could be better tolerated and more beneficial.
Choice B Reason:
Administering an antiemetic after each meal assumes that the client will experience nausea or vomiting regularly after eating. This might not be the case for all clients with AIDS and may not be necessary if the primary issue is malnutrition without associated frequent vomiting.
Choice C Reason:
Seasoning foods with spices might improve the taste of food and potentially stimulate appetite, but it's not as direct or comprehensive a measure for addressing malnutrition as providing a high-calorie diet.
Choice D Reason:
Provide a high-calorie diet is correct. Clients with AIDS often experience malnutrition due to various factors such as decreased appetite, difficulty eating, or malabsorption. Offering a high-calorie diet can help address nutritional deficiencies and support the body's increased energy needs.
