The licensed prescriber orders 60 mg of prednisone po twice a day for a patient who weighs 30 kg. It is available as 15 mg/5 mL. Recommended dosage is 0.5 to 2 mg/kg/24 h given in one or two doses. Maximum dose is 80 mg/24 h
Is this a safe and therapeutic dose?
No
Yes
The Correct Answer is B
Patient's prescribed dose: 60 mg × 2 = 120 mg/24 hr
Maximum recommended dose: 80 mg/24 hr
Patient's weight: 30 kg
Recommended dosage range:
0.5 mg/kg × 30 kg = 15 mg/day
2 mg/kg × 30 kg = 60 mg/day
The prescribed 120 mg/day exceeds both the maximum safe dose of 80 mg/day and the therapeutic range for this patient (15–60 mg/day).
Therefore, the dose is not safe.

Correct Answer is A
Explanation
A. One of the earliest and hallmark signs of malignant hyperthermia (MH) is generalized muscle rigidity, especially masseter (jaw) muscle rigidity after administration of succinylcholine or volatile anesthetics. This occurs due to a genetic defect in calcium regulation in skeletal muscles.
B. Hypotension may occur later in the progression of MH due to cardiovascular collapse, but it is not an early sign.
C. MH is characterized by rapidly increasing body temperature (hyperthermia), not hypothermia.
D. Tachycardia (increased heart rate) is usually seen early in MH, not bradycardia (decreased heart rate).
Correct Answer is D
Explanation
A. Gas forming in bowel contents may occur due to bacterial activity, but this does not explain the clinical significance of flatus in the context of paralytic ileus recovery.
B. Flatus indicating inadequate decompression is incorrect; flatus usually suggests that gas is moving through the intestines, not that it is accumulating.
C. Flatus resulting from forceful vomiting is inaccurate; vomiting expels stomach contents, not intestinal gas, and does not produce flatus.
D. The passage of flatus is a key sign that bowel motility is resuming, which is especially significant in a client with a previously diagnosed paralytic ileus.
