A nurse in the operating room is caring for a client who suddenly develops muscle rigidity and a rise in body temperature. What emergency medication should the nurse expect to receive an order to start administering?
dantrolene
neostigmine
vecuronium
naloxone
The Correct Answer is A
Choice A reason: This is the correct answer. Dantrolene is the medication of choice for treating malignant hyperthermia, which is indicated by muscle rigidity and a rapid rise in body temperature. It works by reducing calcium release in muscles, thereby alleviating the symptoms.
Choice B reason: Neostigmine is an acetylcholinesterase inhibitor used to treat myasthenia gravis and to reverse the effects of certain muscle relaxants post-surgery. It is not indicated for the treatment of malignant hyperthermia.
Choice C reason: Vecuronium is a muscle relaxant used during anesthesia to induce muscle relaxation. It is not a treatment for malignant hyperthermia and does not address the symptoms of muscle rigidity and hyperthermia.
Choice D reason: Naloxone is an opioid antagonist used to reverse the effects of opioid overdose. It has no role in the treatment of malignant hyperthermia and is therefore not relevant to this scenario.

Correct Answer is A
Explanation
Choice A reason:
Respiratory rate is the priority assessment before administering morphine because morphine can cause respiratory depression, a serious side effect. Monitoring the client's respiratory status ensures that the morphine does not significantly depress their breathing, which could lead to life-threatening hypoventilation.
Choice B reason:
While monitoring urine output is important for overall patient care, it is not the immediate priority before morphine administration. Morphine's primary concern is its impact on the respiratory system rather than renal function.
Choice C reason:
Assessing bowel sounds is relevant for managing potential constipation due to morphine use but is not the immediate priority before administration. Respiratory rate takes precedence because of the risk of respiratory depression.
Choice D reason:
Pupil reaction can indicate narcotic effect and neurological status but is not the immediate priority over respiratory rate. Ensuring the client’s respiratory status is stable is the most crucial step before administering morphine.
Correct Answer is C
Explanation
Choice A reason:
Supplemental therapy refers to the use of additional substances or interventions to support and enhance the primary treatment. This is not relevant to the scenario described, where antibiotics are given while awaiting culture results. Supplemental therapy does not describe the preemptive use of antibiotics based on clinical judgment without confirmed microbiological evidence.
Choice B reason:
Replacement therapy typically involves providing the body with necessary substances that it is lacking, such as insulin for diabetes or thyroid hormones for hypothyroidism. This term does not apply to the scenario of administering antibiotics while waiting for culture results. Replacement therapy is used to restore normal function when the body is deficient in certain hormones or enzymes, not for treating infections.
Choice C reason:
Empiric therapy is the correct term for the administration of antibiotics based on clinical signs and symptoms before the exact cause of the infection is confirmed by culture results. This approach is used to promptly manage infections
and prevent their spread while waiting for detailed diagnostic information. It is a common practice in medicine to
