100% CORRECT – CHAMBERLAIN
A patient is taking aminophylline for their COPD. The patient is about to undergo emergency surgery and will receive a neuromuscular junction (NMJ) blocker as part of the procedure.It is important for the nurse to take what action?
ANSWER: Monitor the patient very closely for sign of early
arousal and return of muscle function.
ANSWER: Aminophylline (a xanthine) can reverse NMJ
blockers, necessitating close monitoring.
The nurse is caring for a patient who is being maintained on a mechanical ventilator. Atracurium is administered to limit the resistance to mechanical ventilation. What is the nurse's priority assessment?
- | Page
ANSWER: Bradycardia
ANSWER: Atracurium can cause histamine release, leading to
bradycardia as a key adverse effect.
The nurse is preparing a patient for surgery who will receive a neuromuscular junction blocker during the procedure. It is important for the nurse to review the patient's medication history for concurrent use of what?
ANSWER: Calcium channel blockers
ANSWER: These can enhance NMJ blocker effects, increasing
paralysis risk.
An elderly patient has received a neuromuscular junction blocker during surgery. What would be an appropriate nursing diagnosis for this patient?
- | Page
ANSWER: Risk for impaired skin integrity
ANSWER: Immobility from NMJ blockers heightens skin
breakdown risk in the elderly.
What are the primary uses of neuromuscular junction blockers (NMJ blockers)?
ANSWER: To facilitate endotracheal intubation
ANSWER: To prevent injury during electroconvulsive therapy
ANSWER: To facilitate mechanical ventilation
ANSWER: These are standard clinical applications of NMJ
blockers.
The pharmacology instructor is discussing nondepolarizing neuromuscular junction blockers (NMJ blockers) with the

nursing class. How would the instructor explain the action on nondepolarizing NMJ blockers?
ANSWER: Acts like Ach then prevents repolarization
ANSWER: Nondepolarizing blockers compete with
acetylcholine (Ach), blocking repolarization (corrected from likely intended "Acts as an antagonist to Ach").
According to the sliding filament theory, what is the initial action in a muscle contraction?
ANSWER: Actin and myosin molecules react with each other
sliding along the filament and making it shorter.
ANSWER: This describes the cross-bridge formation initiating
contraction.
