MULTIPLE CHOICE

 

A client is brought to the postanesthesia care unit (PACU) following a cholecystectomy. In the operating room, the client received a mixture of nitrous oxide and oxygen as a primary anesthetic, and anesthesia was induced with ketamine (Ketalar). The nurse receives a report from the anesthetist and begins to care for the client. The following questions refer to this situation and to background knowledge required for working in the PACU.

 

1. The client is in a stage of anesthesia known as analgesia. This stage is:

a.	stage 1.	c.	stage 3.
b.	stage 2.	d.	stage 4.

 

 

ANS:  A

 

	Feedback
A	Correct: Stage 1 is the stage of analgesia.
B	Incorrect: Stage 2 is the stage of excitation.
C	Incorrect: Stage 3 is the stage of surgical anesthesia.
D	Incorrect: Stage 4 is the stage of medullary paralysis.

a.	sedative-hypnotic.	c.	analgesic.
b.	local anesthetic.	d.	anticholinergic.

 

 

ANS:  C

 

	Feedback
A	Incorrect: Fentanyl will produce sedation, but is not classified as a sedative-hypnotic.
B	Incorrect: Fentanyl is not a local anesthetic.
C	Correct: Fentanyl is classified as an opioid analgesic.
D	Incorrect: Fentanyl is not an anticholinergic.

3. Droperidol (Inapsine) is used as a preanesthetic medication primarily because of its ability to act as a(n):

a.	opioid analgesic.	c.	anticholinergic.
b.	antiemetic.	d.	muscle relaxant.

 

 

ANS:  B

 

	Feedback
A	Incorrect: It is not an opiod analgesic.
B	Correct: It is an anti-anxiety and antiemetic agent.

a.	diazepam (Valium).	c.	meperidine (Demerol).
b.	mepivacaine HCl.	d.	epinephrine.

 

 

ANS:  D

 

	Feedback
A	Incorrect: Diazepam is not used for this purpose.
B	Incorrect: Mepivacaine HCl is a regional anesthetic agent.
C	Incorrect: This is not a purpose for meperidine.
D	Correct: Epinephrine causes vasoconstriction to delay absorption of regional anesthetic agents.

5. Malignant hyperthermia is believed to be the result of:

a.	stress and an inherited susceptibility to develop the disorder.
b.	operating rooms that are kept too warm.
c.	the use of spinal anesthesia, rather than general anesthesia.
d.	the lights and heavy drapes used in operating rooms.

 

 

ANS:  A

 

	Feedback
A	Correct: Stress and inherited susceptibility is believed to cause this response to general anesthesia, especially succinylcholine.
B	Incorrect: Operating rooms are kept cool.
C	Incorrect: This is not associated with spinal anesthesia.
D	Incorrect: These do not predispose a client to malignant hyperthermia.
