procedure?
a. Topical benzocaine spray to the area
b. Spinal anaesthesia with mepivacaine hydrochloride
c. Topical prilocaine cream (EMLA®) around the site
d. Infiltration of the area with tetracaine hydrochloride
d. Infiltration of the area with tetracaine hydrochloride
A patient is to receive local anaesthesia for removal of a lymph node from the groin. Why
does the physician add epinephrine to the local anaesthetic during the preparation?
a. Epinephrine prevents an anaphylactic reaction from occurring.
b. The anaesthetic enhances the effect of the epinephrine.
c. Epinephrine contributes to a balanced anaesthetic state.
d. Vasoconstrictive effects keep the anaesthetic at its local site of action.
d. Vasoconstrictive effects keep the anaesthetic at its local site of action.
During the postoperative recovery period, what should be the nurse’s immediate main concern? a. Pupil responses b. Return to sensation c. Level of consciousness
d. Airway, breathing, and circulation
d. Airway, breathing, and circulation
While monitoring a patient who had surgery under general anaesthesia 2 hours earlier, the
nurse notes a sudden elevation in body temperature. What does this sudden elevation in body
temperature indicate?
a. Tachyphylaxis
b. Postoperative infection
c. Malignant hypothermia
d. Malignant hyperthermia
d. Malignant hyperthermia
Which individual is at high risk for an altered response to anaesthesia?
a. A 30-year-old male who has never had surgery before
b. A 45-year-old female who stopped smoking 10 years ago
c. A 20-year-old male who is to have a lymph node removed
d. A 78-year-old female who is to have her gallbladder removed

A patient is undergoing abdominal surgery and has been anaesthetized for 3 hours. Which
nursing diagnosis is appropriate for him?
a. Anxiety related to the use of an anaesthetic
b. Risk for injury related to increased sensorium from general anaesthesia
c. Decreased cardiac output related to systemic effects of local anaesthesia
d. Impaired gas exchange related to central nervous system (CNS) depression
produced by general anaesthesia
d. Impaired gas exchange related to central nervous system (CNS) depression
produced by general anaesthesia
When administering a neuromuscular drug such as pancuronium, what does the nurse need to
remember?
a. It can be used instead of general anaesthesia during surgery.
b. Only skeletal muscles are paralyzed; respiratory muscles remain functional.
c. It causes sedation and pain relief while allowing for lower doses of anaesthetics.
d. Patients will require artificial mechanical ventilation because of paralyzed
respiratory muscles.
d. Patients will require artificial mechanical ventilation because of paralyzed
respiratory muscles.
A patient has been given succinylcholine (Quelicin®) after a severe injury that necessitated
controlled ventilation. The physician now wants to reverse the paralysis. The nurse would
expect to use which drug to reverse the succinylcholine?
a. diazepam (Valium®)
b. caffeine
c. neostigmine methylsulphate
d. vecuronium bromide (Norcuron®)
c. neostigmine methylsulphate
A patient is being prepared for an oral endoscopy, and the nurse reminds him that he will be
awake during the procedure but probably will not remember it. What type of anaesthetic
technique is used in this situation?
a. Twilight sleep
b. Procedural sedation
c. Adjunctive anaesthesia
d. Spinal anaesthesia
b. Procedural sedation
Which symptom may occur if a patient is taking ginger and requires an anaesthetic?
a. Decreased blood pressure
b. Increased risk of bleeding
c. Increased risk of stroke
d. Migraine headaches
b. Increased risk of bleeding
