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

Answer and Explanation

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 B

Explanation

A. Assessing the WBC count is not directly related to the administration of a nonselective adrenergic blocker. These medications primarily affect the cardiovascular system.
B. Assessing pulse and blood pressure is crucial before administering a nonselective adrenergic blocker. These medications can cause bradycardia and hypotension as side effects, so it's
important to ensure the client's baseline pulse and blood pressure are within acceptable ranges before giving the medication.
C. Assessing bowel sounds is not directly related to the administration of a nonselective adrenergic blocker. These medications primarily affect the cardiovascular system.
D. Assessing serum sodium and potassium levels is not directly related to the administration of a nonselective adrenergic blocker. These medications primarily affect the cardiovascular system.

A. Decreased urine output B. Increased cardiac output C. Volume restoration D. Reduced anxiety

Correct Answer is B

Explanation

A. Decreased urine output is not the primary intended effect of an adrenergic agonist in the

treatment of shock. While adrenergic agonists may increase blood pressure, leading to a decrease in urine output due to vasoconstriction, the primary goal of administering these drugs in shock is to improve tissue perfusion and cardiac output.
B. Increased cardiac output is the primary intended effect of adrenergic agonists in the treatment of shock. These medications stimulate adrenergic receptors, leading to increased heart rate, contractility, and stroke volume, ultimately improving cardiac output and tissue perfusion.
C. Volume restoration may be a secondary effect of administering fluids along with adrenergic agonists in the treatment of shock, but it is not the primary intended effect of the medication
itself.

D. Reduced anxiety is not a primary goal of administering adrenergic agonists in the treatment of shock. While these medications may have anxiolytic effects in certain situations, the primary goal is to improve cardiovascular function and tissue perfusion.
