QUESTIONS WITH ANSWERS GRADED A+
◉Which of the following is needed to complete the circuit on an ESU
when using a monopolar electrode tip?
A. a bipolar forceps
B. an insulated holster
C. an active electrode
D. a dispersive pad. Answer: D. The dispersive pad disperses high-
frequency current released through the active electrode and
provides low current density return from tissues back to the
generator to complete the circuit.
◉A complication of steep reverse Trendelenburg position is
A. deep vein thrombosis.
B. arterial compression.
C. cardiac overload.
D. respiratory alkalosis.. Answer: A. Steep reverse Trendelenburg
position decreases venous return. Sequential compression stockings
are applied to prevent deep venous thrombosis.
,◉The topical hemostatic agent thrombin should never be directly
injected or allowed to enter into a vessel because
A. it causes uncontrollable vasospasms.
B. the effects are reversed when directly injected and cause more
severe bleeding.
C. it can cause clotting and may ultimately lead to death.
D. the risk of infection increases with direct injection.. Answer: C.
Thrombin will cause blood in the vessel to clot and will cause
thrombosis, which can lead to death if not realized and corrected
immediately.
◉According to Maslow's Hierarchy of Needs, which of the following
patient needs should be met first?
A. esteem
B. belonging
C. physiological
D. safety. Answer: C. Physiological needs must be met first before any
of the other needs can be considered. Physiological needs include
breathing, circulation, and the patient's physical condition.
◉An epidural catheter is introduced into a patient in the
preoperative holding room. When the patient is given a bolus of local
anesthetic in the OR, the surgical first assistant observes
, hypotension and signs of complete respiratory failure. Which of the
following is the MOST likely cause?
A. migration of the epidural catheter through the dura
B. poor cardiac output
C. administration of ropivacaine instead of bupivacaine
D. use of a Bier block. Answer: A. With patient movement, the
epidural catheter may migrate through the dura. A bolus injection
into the subdural space can cause total spinal anesthesia resulting in
hypotension and respiratory failure.
◉Taper point needles are generally used in which of the following
tissue types?
1. gastrointestinal
2. tendons
3. adipose
4. vascular. Answer: 1. It is used on GI tissues to reduce the amount
of tissue trauma.
3. Adipose is a less dense tissue and a taper needle works well.
4. Vascular tissue needs a taper to prevent further tissue damage as
well.
◉A threaded cortical screw cannot provide compression of bone
fragments unless the
A. hole is tapped.
