Tachypnea

Skin mottling

High body temperature

Answer and Explanation

Correct Answer : A,C,D,F

Muscle rigidity is a hallmark sign of malignant hyperthermia. It commonly affects the muscles of the jaw and upper chest.

Malignant hyperthermia can lead to rapid and shallow breathing, resulting in tachypnea. Malignant hyperthermia is characterized by a significant increase in body temperature, often exceeding 38.8°C (101.8°F).

Malignant hyperthermia can cause irregular heart rhythms or dysrhythmias, including tachycardia or arrhythmias.

The manifestations of hypertension and skin mottling are not typically associated with malignant hyperthermia. Hypertension (high blood pressure) is more commonly seen in conditions such as hypertensive emergencies or certain cardiovascular disorders. Skin mottling, which refers to irregular or patchy skin coloration, is not a specific manifestation of malignant hyperthermia.

Correct Answer is D

Explanation

To calculate the milliliters per hour (mL/hr) for the IV infusion, you divide the total volume (in milliliters) by the total time (in hours).

In this case, the total volume is 1 liter, which is equal to 1000 milliliters, and the total time is 6 hours.

So, you divide 1000 mL by 6 hours:

1000 mL / 6 hours = 166.67 mL/hr

Rounding off, the nurse will program the IV infusion device to infuse at approximately 167 mL/hr.

A. "I will weigh myself daily and report to my physician if I gain more than 3 lbs in 1 day." B. "This medication can cause dehydration, so I will stay hydrated by consuming at least 2 L or more of fluid per day." C. "I will eat a diet rich in potatoes, bananas, avocadoes, strawberries, and spinach." D. "I will change position slowly because I can become dizzy easily while taking this medication."

Correct Answer is C

Explanation

Loop diuretics, such as furosemide, are known to promote diuresis (increased urine output) and can cause electrolyte imbalances, including low potassium (hypokalemia). The patient's statement about eating a diet rich in potassium-containing foods like potatoes, bananas, avocadoes, strawberries, and spinach is incorrect in this context. These foods are indeed good sources of potassium, but when taking loop diuretics, it is necessary to monitor and potentially restrict potassium intake to prevent excessive potassium levels.

"I will weigh myself daily and report to my physician if I gain more than 3 lbs in 1 day." This statement reflects the patient's understanding of the need to monitor their weight daily as a means of assessing fluid balance. Rapid weight gain may indicate fluid retention, which should be reported to the physician.

"This medication can cause dehydration, so I will stay hydrated by consuming at least 2 L or more of fluid per day." This statement demonstrates awareness of the potential for dehydration when taking loop diuretics and the importance of staying adequately hydrated by consuming an appropriate amount of fluids.

"I will change position slowly because I can become dizzy easily while taking this medication." This statement reflects the understanding that loop diuretics can cause orthostatic hypotension,

leading to dizziness upon sudden changes in position. Taking precautions and changing position slowly can help prevent falls and related injuries.
