Test Questions and Correct Answers
After the nurse administers a cholinergic medication to the client, the nurse would
monitor for which effect because of the drug's actions on the body?
- Dry mouth
- Constipation
- Increased heart rate
- Constricted pupils ✅constricted pupils
Rationale (#4), page 896: Cholinergic medications stimulate the parasympathetic
nervous system, with the following effects: decreased heart rate; increased secretions
from glands; constricted pupils; increased motility of the GI tract.
What is the function of the enzyme acetylcholinesterase?
- It breaks down norepinephrine
- It breaks down acetylcholine
- It enhances the effects of norepinephrine
= It enhances the effects of acetylcholine ✅It breaks down acetylcholine
For a drug that is identified as a beta1 agonist, which of the following effects could you
expect to see? SELECT ALL THAT APPLY.
-Vasoconstriction
- Increased force of contraction!
- Increased speed of electrical conduction
-Relaxation of smooth muscle
- Increased HR ✅- Increased force of contraction!
- Increased speed of electrical conduction
- Increased HR
Rationale (#17): page 568 (chapter 29): Beta1 predominant effects are increased force
of contraction; increased heart rate; increased speed of electrical conduction; increased
renin production.
The expected therapeutic effects of anticholinergic drugs when used for GU
(genitourinary) issues such as urinary incontinence, cystitis, or enuresis, are any of the
following, EXCEPT:
-Reduces urinary muscle spasm
-Decreases pain & frequency
- Increases urinary urgency
-Increases bladder capacity ✅increases urinary urgency
Rationale (#5): pg 929 (chapter 48, Table 48.6): Genitourinary effects with
anticholinergic use can include: reducing urinary muscle spasm (for urinary
, incontinence and frequency); decreases pain and frequency (for cystitis, urethritis, and
prostatitis); increases bladder capacity (for enuresis, paraplegia, and neurogenic
bladder).
Which of the following are expected effects after administration of the
acetylcholinesterase inhibitor drug, neostigmine (Bloxiverz) that has been prescribed for
a patient with myasthenia gravis?
- Increased heart rate and cardiac output
- Decreased gastric motility
- Increased muscle strength
- Fewer tremors ✅increased muscle strength
A patient in a cholinergic crisis has been ordered atropine sulfate 0.4 mg IV times 1
now. The atropine sulfate preparation is 0.5 mg/5 mL. How much volume will you draw
up to administer? (Round to the nearest tenth; Use a leading zero if it applies; Do not
use a trailing zero; Indicate the number and the appropriate dosage unit in your answer)
✅4 mL
The Black Box Warning for the beta-blocker, propranolol states that abrupt
discontinuation of the drug can:
- Cause severe bronchoconstriction
- Exacerbate cardiac ischemia
- Cause severe bradycardia
- Cause seizures ✅- Exacerbate cardiac ischemia
Which of the following is a symptom of an anticholinergic overdose?
- Diaphoresis
- Hypothermia
- Bradycardia
- Dry mouth ✅dry mouth
Rationale (#11): pg 932: anticholinergic overdose symptoms are characterized by:
hyperthermia; hot, dry, flushed skin; dry mouth; mydriasis; delirium; tachycardia;
paralytic ileus; urinary retention; may have myoclonic movements and
choreoanthetosis; seizure, coma, and respiratory arrest may also occur.
The nurse is caring for a client with the following vital signs: blood pressure (BP) 78/42;
heart rate (HR) 52; respiratory rate (RR) 26, glucose 60 mg/dL; cardiac output (CO) 3.5
L/min (normal range 4-6 L/min). After administration of a sympathomimetic (beta1-
adrenergic agonist) medication, the nurse would predict which of the following changes
in vital signs?
- CO 3.2 L/min
- HR 44; BP 74/40
- Glucose 50 mg/dL
- HR 70; BP 110/74 ✅- HR 70; BP 110/74
