2. A patient who has been using Theo-Dur at home states that she experiences palpitations, nausea,
vomiting, headache, and agitation each time after taking the medication. The proper management
technique for this patient includes monitoring of the _______ level and titrating the dosage to a thera-
peutic range of _______.

A. serum theophylline, 5–15 mcg/mL C. serum theophylline, 40–60 mcg/mL
B. corticosteroid, 5–15 mcg/mL D. corticosteroid, 40–60 mcg/mL

3. An asthmatic patient who has been using Ventolin for several months complains of shortness of breath
and states that “the Ventolin is not working any more.” The physician asks a therapist for suggestion.
The therapist should recommend a trial use of:

A. Proventil. C. Brethine.
B. Alupent. D. Vanceril.

4. Which of the following is not an indication for using a neuromuscular blocking agent?
A. relieve laryngeal spasm C. facilitate endotracheal suctioning
B. maintain mechanical ventilation D. enhance endotracheal intubation

5. Succinylcholine (Anectine, Quelicin) is a _______ neuromuscular blocking agent. It induces muscle
blockade by _______.

A. depolarizing, binding to the receptor sites and causing sustained depolarization
B. nondepolarizing, binding to the receptor sites and causing sustained depolarization
C. depolarizing, competing for the receptor sites and blocking the action of acetylcholine
D. nondepolarizing, competing for the receptor sites and blocking the action of acetylcholine

6. All of the following are potential complications of a neuromuscular blocking agent except :
A. oversedation. C. apnea.
B. prolonged muscle blockade. D. bronchospasm.

7. A patient who has been given Norcuron one hour ago is recovering in the surgical intensive care unit. The
physician wants to know whether neuromuscular blockade reversal has occurred. The therapist should
check all of the following except:

A. tongue protusion. C. hand grip.
B. serum acetylcholine level. D. head lift.

8. A mechanically ventilated patient has been receiving diazepam (Valium) for better tolerance of
mechanical ventilation and related procedures. The cardiovascular adverse effects for his patient may
include:
A. decreased cardiac output. C. increased mean arterial pressure.
B. increased stroke volume. D. increased systemic vascular resistance.

9. The Ramsay Scale is commonly used to assess the degree of:
