Which condition is characterized by hypotension, bronchospasm, and urticaria occurring after drug administration, requiring immediate epinephrine treatment?
Answer: Anaphylaxis
Anaphylaxis is a severe, life-threatening allergic reaction involving IgE-mediated mast cell degranulation, treated immediately with epinephrine 0.3–0.5 mg IM.
What is the correct concentration of epinephrine typically used in a 1:1,000 solution for anaphylaxis treatment?
Answer: 1 mg/mL
A 1:1,000 epinephrine solution contains 1 mg per mL, which is the concentration used for intramuscular injection in anaphylaxis.
A scrub technologist receives a syringe labeled 'Vasopressin 20 units' for a laparoscopic hysterectomy. What is its primary surgical use?
Answer: To constrict blood vessels and reduce local bleeding
Vasopressin is injected locally to cause vasoconstriction, significantly reducing blood loss during gynecologic and other surgeries.
Which route of administration provides the fastest onset of drug action in emergency situations?
Answer: Intravenous (IV)
Intravenous administration delivers drugs directly into the bloodstream, providing immediate bioavailability and the fastest onset of action.
What does the term 'half-life' of a drug refer to in pharmacokinetics?
Answer: Time for 50% of the drug to be eliminated from the body
Half-life (t½) is the time required for plasma concentration of a drug to decrease by 50%, which determines dosing intervals and time to steady state.
Which topical hemostatic agent derived from bovine thrombin combined with gelatin is commonly applied to surgical sites to control bleeding?
Answer: Floseal
Floseal is a hemostatic matrix combining bovine-derived gelatin granules and thrombin that swells to tamponade bleeding and activates the coagulation cascade.
When administering medications on the sterile field, what is the correct way to accept a drug from the circulator?
Answer: The circulator pours or drops the drug into a labeled sterile cup held by the scrub
The circulator pours or drops the drug into a sterile, labeled receptacle held by the scrub to maintain aseptic technique and prevent contamination.
