- A. Prednisone
- B. Oxycodone
- C. Diclofenac
- D. Dexamethasone
- E. Ibuprofen
Correct Answer: A,D

When assessing a client receiving a cholinergic drug, the nurse would assess the client for increased neuromuscular blocking effects if the client is also receiving which of the following?
- A. Amoxicillin
- B. Tobramycin
- C. Cephalexin
- D. Neomycin
- E. Clarithromycin
Correct Answer: B,D
Rationale: Cholinergic drugs administered concomitantly with aminoglycoside antibiotics, like tobramycin and neomycin, can result in increased neuromuscular blocking effects.
A client has been prescribed pyridostigmine for myasthenia gravis. The nurse would be alert for the development of which of the following?
- A. Seizure disorder
- B. Reduction of visual acuity
- C. Abdominal discomfort
- D. Cardiac arrhythmias
Correct Answer: D
Rationale: The nurse should monitor for cardiac arrhythmias as a general adverse reaction in the client. Seizure disorder, reduction of visual acuity, and abdominal discomfort are not pyridostigmine-related adverse reactions. Reduction of visual acuity is related to topical ophthalmics. When the client is receiving bethanechol chloride for urinary retention, the nurse needs to examine for abdominal discomfort, which is an adverse reaction of bethanechol chloride and not pyridostigmine.
A nurse is caring for a client with urinary retention who is receiving a cholinergic drug as part of the treatment plan. After administering the drug, the nurse would notify the primary health care provider if the assessment reveals which of the following?
- A. Failure to void after drug administration
- B. Frequent vomiting after drug administration
- C. Increase in abdominal pain after drug administration
- D. Occurrence of blood in urine after drug administration
Correct Answer: A
Rationale: The nurse should notify the primary health care provider if the client fails to void after drug administration. Frequent vomiting, increase in abdominal pain, and occurrence of blood in urine are not usually observed when urinary retention is treated with cholinergic therapy.
After teaching a group of nursing students about the parasympathetic nervous system, the instructor determines that the teaching was successful when the students identify which of the following as an action?
- A. Decreased salivary gland production
- B. Vasodilation
- C. Increased peristalsis
- D. Bronchodilation
- E. Pupillary constriction
Correct Answer: B,C,E
Rationale: Stimulation of the parasympathetic nervous system results in the opposite reactions to those triggered by the adrenergic system: blood vessels dilate, sending blood to the gastrointestinal (GI) tract; secretions and peristalsis are activated and salivary glands increase production; the heart slows and pulmonary bronchioles constrict; the smooth muscle of the bladder contracts; and the pupils of the eyes constrict.
The nurse understands that the drug would be appropriate for which condition?
- A. Urinary retention
- B. Overactive bladder
- C. Myasthenia gravis
- D. Parkinson's disease
- E. Graves' disease
Correct Answer: A,C
Rationale: Cholinergic drugs can be used to treat urinary retention, myasthenia gravis, and glaucoma.
