A nurse is monitoring a client who has diabetes mellitus and a glucose level of 384 mg/dl. (74 to 106 mg/dL). Which of the following findings should the nurse identify as an indication of metabolic acidosis?

Choice A Reason:
"I'll make sure I stay away from microwave ovens." This statement is incorrect . While there were concerns about interference in the past, modern pacemakers are generally not affected by household appliances like microwave ovens.
Choice B Reason:
"I should have an MRI, rather than a CAT scan, if necessary." This statement is incorrect. Both MRI and CAT scans have considerations when a person has a pacemaker. An MRI might be contraindicated due to the magnetic field, while a CAT scan might be a safer imaging choice.
Choice C Reason:
"I'll hold my cell phone against the ear on the opposite side of my body." This statement reflects an understanding of the precaution to avoid holding a cell phone directly over the implanted pacemaker. Keeping the phone on the opposite side helps minimize the potential interference with the pacemaker's function.
Choice D Reason:
"I shouldn't travel by plane because of airport security." This statement is incorrect. Airport security systems generally don't affect pacemakers, so traveling by plane is usually safe. However, informing security personnel about the presence of a pacemaker is a good practice.

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.
