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 B
Explanation
Choice A reason:
Monitoring the Glasgow Coma Scale (GCS) is used to assess a client's level of consciousness, typically in cases of head injury or altered mental status. It is not relevant to the assessment of a pressure injury, which requires evaluating the risk factors and extent of skin damage.
Choice B reason:
Completing the Braden Scale is the appropriate action for assessing a client with a pressure injury. The Braden Scale evaluates risk factors for pressure ulcers, including sensory perception, moisture, activity, mobility, nutrition, and friction/shear. This tool helps in creating an effective care plan to prevent further skin breakdown and manage existing ulcers.
Choice C reason:
Initiating a Brudzinski flow sheet pertains to neurological assessment, specifically testing for signs of meningitis. It is not relevant to the assessment or management of pressure injuries in a paraplegic client.
Choice D reason:
Assessing for Babinski's sign is a neurological test to evaluate corticospinal tract function. While important in a complete neurological examination, it does not address the specific needs related to pressure injury assessment and management.
Correct Answer is B
Explanation
Choice A reason:
Assessing sputum characteristics is important in monitoring respiratory conditions but does not directly precede preparing a client for postural drainage. It assesses the infection or inflammation severity, providing valuable data for treatment but isn't the immediate preparatory step for drainage.
Choice B reason:
Assessing pulse and respirations is critical before starting postural drainage as it establishes the client’s baseline vital signs and ensures they can tolerate the procedure. Monitoring these vital signs throughout ensures safety and effectiveness of the procedure. Thus, it’s the essential first step.
Choice C reason:
Instructing on pursed-lip exhalation aids in managing respiratory conditions by promoting effective breathing patterns but is not the immediate first step before percussion and postural drainage. It serves more as a therapeutic breathing technique.
Choice D reason:
Auscultating lung fields identifies lung sounds and areas needing drainage but isn’t the initial action. While important for confirming indications and evaluating effectiveness, it follows baseline assessments like pulse and respirations.
