During the immediate postoperative period, the Post Anesthesia Care Unit nurse is assessing a patient who had hip surgery. The patient is experiencing tachycardia, tachypnea, and muscle rigidity, and his temperature is 103°F (39.4°C). The nurse will prepare for what immediate treatment?
Dantrolene injection, a skeletal muscle relaxant
Cardiopulmonary resuscitation (CPR) and intubation
An anticholinesterase drug, such as neostigmine
Naltrexone hydrochloride injection, an opioid reversal drug
The Correct Answer is A
A. Dantrolene injection, a skeletal muscle relaxant: The patient is exhibiting signs of malignant hyperthermia, a potentially life-threatening complication of anesthesia. Dantrolene is the primary treatment for malignant hyperthermia as it acts as a skeletal muscle relaxant, reducing muscle rigidity and hypermetabolism associated with the condition.
B. Cardiopulmonary resuscitation (CPR) and intubation: While the patient is experiencing significant physiological distress, initiating CPR and intubation would be premature without first addressing the underlying cause, which appears to be malignant hyperthermia.
C. An anticholinesterase drug, such as neostigmine: Anticholinesterase drugs like neostigmine are not indicated for the treatment of malignant hyperthermia.
D. Naltrexone hydrochloride injection, an opioid reversal drug: Naltrexone is used for opioid overdose reversal and is not appropriate for the treatment of malignant hyperthermia.

Correct Answer is ["28"]
Explanation
2 cups of coffee: 2 cups 8 oz/cup = 16 oz
1 soft drink: 12 oz
Total intake from 1500 to 2100 = 16 oz (coffee) + 12 oz (soft drink) = 28 oz
From 2100 to 2300 (2 hours):
No additional intake mentioned in the question.
Total intake from 1500 to 2300 = 28 oz (from 1500 to 2100)
Therefore, the total intake from 1500 to 2300 is 28 ounces.
Correct Answer is D
Explanation
A. Tachycardia is not typically associated with cholinergic drug effects. Cholinergic stimulation tends to slow down the heart rate rather than increase it.
B. Palpitations may occur with certain cardiac arrhythmias or in response to sympathetic stimulation, but they are not typically associated with cholinergic drug effects.
C. Cholinergic drugs are more likely to cause vasodilation rather than vasoconstriction.
Therefore, vasoconstriction is not a common cardiovascular effect of cholinergic drug therapy.
D. Bradycardia is a common cardiovascular effect of cholinergic drug therapy. Cholinergic stimulation slows down the heart rate by increasing parasympathetic activity, particularly at the
sinoatrial (SA) node. Therefore, bradycardia is the cardiovascular effect that nurses should monitor for when administering cholinergic drugs.
