A patient undergoing a regional anesthetic block in pre-op prior to a knee arthroscopy suddenly becomes shaky, tachycardic, hypertensive, and feels like they have palpitations. The medication used in the block was ropivacaine with epinephrine and they were premedicated with lorazepam. What are their symptoms most likely a result of?
Correct — B. Answer: The epinephrine. Epinephrine is added to local anesthetics to increase longevity through vasoconstriction. It is a potent stimulant and can cause an adrenergic response. Symptoms of overdose include tremors, nervousness, pallor, diaphoresis, palpitations, tachycardia, and hypertension. The maximum dose of ropivacaine with epinephrine should be carefully monitored to prevent systemic toxicity. -
CNAMB Exam Prep
A patient is scheduled for carpal tunnel release surgery under regional anesthesia using a femoral nerve block. What special supply is particularly important for this type of block?
Correct — B. Answer: A nerve stimulator Femoral nerve blocks are a type of regional anesthesia where the local anesthetic is injected near the femoral nerve to block sensation in the surgical area. A nerve stimulator is often used to help the anesthesiologist locate the nerve precisely by causing muscle contractions when the femoral nerve is close. -
CNAMB Exam Prep
The pre-operative nurse is assessing a patient scheduled for a laparoscopic appendectomy. The patient takes enalapril QD, levothyroxine QD, albuterol PRN, aspirin QD, and warfarin QD. The patient did not take any of their medications this morning, but took enalapril and warfarin last night at 22:00 (10 pm). They've been NPO since midnight. Which medication would the nurse expect the anesthesia provider to order preoperatively?
Correct — D. Answer: A dose of intravenous vitamin K Since the patient takes warfarin, they are at risk for excessive bleeding during and after the surgery. Warfarin is an anticoagulant, and its effects need to be reversed in the preoperative period to minimize bleeding risks. Vitamin K is given to counteract the effects of warfarin and help in the proper clotting of blood. Another dose of enalapril would not be given because it could lead to perioperative hypotension. Levothyroxine and albuterol are usually continued if they were not missed doses as they do not impact surgery directly in an acute setting. Aspirin also complicates clotting and needs to be stopped before surgery. -
CNAMB Exam Prep
During a minor hand surgery at an ambulatory surgical center, a patient with a known severe allergy to bee stings is given local anesthesia containing lidocaine-epinephrine for the procedure. Shortly after application, the patient complains of lightheadedness, shortness of breath, and their skin appears dusky with a pulse oximetry reading of 82%. What should the nurse do next and what should they ask the first coworker that responds to prepare?
Correct — A. The correct answer is: They should immediately stop the procedure, administer oxygen at 15 liters via a non-rebreather mask, and ask the coworker to grab the anaphylaxis kit and prepare epinephrine for administration. The nurse should suspect anaphylactic reaction since the patient has a known severe allergy. Symptoms like shortness of breath, dusky skin, and low pulse oximetry indicate a serious reaction likely exacerbated by the local lidocaine-epinephrine mixture. Administering high-flow oxygen helps stabilize the patient while waiting for the rapid response team. Epinephrine is the first-line treatment for anaphylaxis as it counteracts severe allergic reaction symptoms by relaxing airway muscles and tightening blood vessels. Without timely administration, the patient risks further deterioration, including potential airway obstruction and cardiovascular collapse. In such scenarios, rapid recognition and treatment are key to preventing complications like hypoxia, hypotension, and shock.
