-Group 1-
- 1.
Cholinergic (parasymphatomimetic) drugs have which of the following therapeutic effects?
- A.
Urinary retention
- B.
Increased GI motility
- C.
Mydriasis
- D.
Vasoconstriction
Correct Answer
B. Increased GI motilityExplanation
Cholinergic effects mimic the parasympathetic nervous system (of rest and digest) as opposed to the sympathetic nervous system (fight or flight). Increasing GI motility helps the body digest. Urinary retention, mydriasis, and vasoconstriction are sympathetic nervous system responses.Rate this question:
-
- 2.
Cholinergic (parasympathomimetic) drugs are indicated for which of the following situations?
- A.
Treating a postoperative client who has bradycardia
- B.
Lowering intraocular pressure in clients with glaucoma
- C.
Inhibiting muscular activity in the bladder
- D.
Preventing salivation and sweating
Correct Answer
B. Lowering intraocular pressure in clients with glaucomaExplanation
Cholinergic agents stimulate the pupil to constrict (miosis), thus decreasing intraocular pressure.Rate this question:
-
- 3.
During postoperative teaching the nurse explains that the client is receiving bethanechol (Urecholine) to treat:
- A.
Postoperative hypotension
- B.
Respiratory atelectasis
- C.
Urinary atony
- D.
Postoperative ischemic colitis
Correct Answer
C. Urinary atonyExplanation
Bethanechol is a direct-acting cholinergic agonist that stimulates the cholinergic receptors on the smooth muscle of the bladder, leading to bladder contraction and emptying.Rate this question:
-
- 4.
Adverse reactions to bethanechol include:
- A.
Constipation
- B.
Hypertension
- C.
Tachycardia
- D.
Abdominal Cramping
Correct Answer
D. Abdominal CrampingExplanation
Side effects of bethanechol include abdominal cramps, diarrhea, hypotension, bradycardia, and headache.Rate this question:
-
- 5.
Cholinergic (parasympathomimetic) drugs should be used cautiously with clients who have a history of:
- A.
Benign prostatic hyperplasia
- B.
Hemorrhoids
- C.
Glaucoma
- D.
Leg cramps
Correct Answer
A. Benign prostatic hyperplasiaExplanation
Increased bladder muscle contractions could prove harmful in clients with benign prostatic hyperplasia secondary to obstruction of urinary outflow.Rate this question:
-
- 6.
Side effects to expect from anticholinergic (parasympatholytic) agents, such as atropine, include all of the following except:
- A.
Dilated pupils (mydriasis)
- B.
Urinary retention
- C.
Dry mouth
- D.
Diarrhea
Correct Answer
D. DiarrheaExplanation
Anticholinergic effects block the effects of the parasympathetic nervous system, producing sympathetic nervous system effects. The effect on the GI system would be to decrease GI motility, not increase it (diarrhea).Rate this question:
-
- 7.
A client presents with symptomatic bradycardia.The nurse prepares to administer which dose of atropine intravenously?
- A.
0.3 mg
- B.
0.5 mg
- C.
1.25 mg
- D.
2 mg
Correct Answer
B. 0.5 mgExplanation
The recommended dose of atropine to treat symptomatic bradycardia is 0.5 to 1 mg.Rate this question:
-
- 8.
A client comes into the emergency room with an overdose of cholinergic drugs.The nurse prepares to administer which dose of atropine intravenously?
- A.
0.3 mg
- B.
0.5 mg
- C.
1.25 mg
- D.
2 mg
Correct Answer
D. 2 mgExplanation
Higher doses of atropine (2-3 mg) are needed to treat cholinergic overdoses.Rate this question:
-
- 9.
A priority nursing diagnosis for a client receiving anticholinergic (parasympatholytic) drugs would be:
- A.
Risk for injury related to excessive CNS stimulation
- B.
Impaired gas exchange related to thickened respiratory secretions
- C.
Urinary retention related to loss of bladder tone
- D.
Knowledge deficit related to pharmacology regimen
Correct Answer
B. Impaired gas exchange related to thickened respiratory secretionsExplanation
Although all of these nursing diagnoses are appropriate, the priority is determined by remembering the ABCs. Anticholinergic drugs decrease respiratory secretions, which could lead to mucous plugs and resultant impaired gas exchange.Rate this question:
-
- 10.
The nurse monitors a client prescribed dicyclomine (Bentyl) for which therapeutic effect?
- A.
Decrease in GI motility
- B.
Decrease in urinary frequency
- C.
Increase in heart rate
- D.
Increase in blood pressure
Correct Answer
A. Decrease in GI motilityExplanation
Dicyclomine is an antispasmodic cholinergic blocker used to decrease GI motility in clients with functional GI disorders such as irritable bowel syndrome.Rate this question:
-
- 11.
A priority assessment of a client on antibiotic therapy includes questioning the client about.
- A.
History of seizure activity
- B.
Cardiac history
- C.
Allergies
- D.
Immunizations
Correct Answer
C. AllergiesExplanation
Antibiotic allergy is one of the most common drug allergies. They also have the potential to cause severe anaphylaxis and death.Rate this question:
-
- 12.
The nurse would monitor which of the following laboratory values for a client receiving intravenous gentamicin (Garamycin)?
- A.
Hematocrit and hemoglobin
- B.
Sodium and cholride
- C.
PT and PTT
- D.
BUN and creatinine
Correct Answer
D. BUN and creatinineExplanation
Gentamycin has a high potential for nephrotoxicity and is thus contraindicated in clients with elevated renal function tests such as BUN and creatinine.Rate this question:
-
- 13.
Discharge teaching for a client receiving tetracycline should include.
- A.
"Take the medication until you feel better"
- B.
"Use suncreen and protective clothing when outdoor"
- C.
"keep the remainder of the medication in case of recurrence"
- D.
"Take the medication with food and milk to minimize GI upset"
Correct Answer
B. "Use suncreen and protective clothing when outdoor"Explanation
Photosensitivity is a common side effect of tetracycline. Exposure to the sun can cause severe burns.Rate this question:
-
- 14.
If tetracycline is administered to children 8 years of age, it can cause:
- A.
Delayed achievement of developmental milestones
- B.
Neurotoxicity
- C.
GI bleeding
- D.
Permanent discoloration of the teeth
Correct Answer
D. Permanent discoloration of the teethExplanation

A client who is allergic to penicillin is at increased risk an allergy to:
- A.
Tetracycline
- B.
Cefazolin sodium (Ancef)
- C.
Gentaminicin (Garamycin)
- D.
Erythomycin
Correct Answer
B. Cefazolin sodium (Ancef)Explanation
There is a cross-sensitivity between penicillin and cephalosporin antibiotics, because they both contain a beta-lactam ring and are thus chemically related.Rate this question:
