Question 1
Multiple Choice
When describing the different cholinergic blockers, which of the following would a nursing instructor include as affecting only the muscarinic receptors?
Correct!
Incorrect
The correct answer is: A,B,E
Rationale
Darifenacin (Enablex) affects only the muscarinic receptors, specifically targeting bladder function to decrease overactive bladder symptoms without impacting nicotinic receptors. This selective action makes it effective for treating urinary urgency and incontinence.
B: Oxybutynin (Ditropan) acts on both muscarinic and nicotinic receptors, which means it has a broader range of effects beyond just the muscarinic receptor influence.
C: Benztropine (Cogentin) is primarily used to manage Parkinson's disease and is designed to block both muscarinic and nicotinic receptors, thus affecting multiple receptor types.
D: Biperiden (Akineton) also targets both muscarinic and nicotinic receptors, making it less selective and not solely affecting the muscarinic receptors as required.
E: Tolterodine (Detrol) influences both types of receptors, leading to a broader spectrum of action than just the muscarinic receptors, affecting urinary function in various ways.

Question 2
Multiple Choice
A nurse suspects that a client who has received scopolamine is experiencing an idiosyncratic reaction to the drug based on assessment of which of the following?
Correct!
Incorrect
The correct answer is: B,D
Rationale
Restlessness indicates an idiosyncratic reaction to scopolamine, as this drug typically causes sedation. The unexpected agitation rather than the anticipated calming effect suggests an atypical response unique to the individual.
A: Drowsiness This side effect aligns with the expected pharmacological action of scopolamine, which is known for its sedative properties, indicating a typical response rather than an idiosyncratic reaction.
C: Hypotension While hypotension can occur with certain medications, it is not a known idiosyncratic effect of scopolamine. This symptom does not suggest an atypical response to the drug.
D: Insomnia Although insomnia may seem unusual, it is not a direct idiosyncratic reaction to scopolamine. Most individuals experience drowsiness, making insomnia a more common side effect than an atypical response.
E: Dry mouth This common side effect is a recognized pharmacological response to scopolamine, rather than an idiosyncratic reaction. It reflects the anticholinergic properties of the medication, not an unexpected response.

Rationale: C: Blurred vision. The use of belladonna, an anticholinergic agent, can lead to visual disturbances due to its effects on the eye muscles and pupil dilation, necessitating close monitoring for this side effect.
A: Disorientation. While belladonna can cause central nervous system effects, disorientation is not a primary concern associated with its use in this context compared to visual disturbances.
B: Lightheadedness. Although anticholinergics may induce dizziness, lightheadedness is less specific and not a direct outcome of belladonna's pharmacological actions, making it a less critical observation.
D: Mydriasis. Although belladonna can cause pupil dilation, monitoring for mydriasis is less relevant than observing for blurred vision, which can significantly impact the client's daily functioning and safety.
Question 20
Regular
A nurse is teaching a client about the increased risk of heat prostration during the hot summer months related to his prescribed scopolamine therapy. The nurse determines that the teaching was successful when the client identifies which of the following as a sign of this condition?
Correct!
Incorrect
The correct answer is: B
Rationale
Fever is a sign of heat prostration, indicating the body's inability to regulate temperature effectively under stress. Scopolamine can impair thermoregulation, making the client more susceptible to overheating and fever.
A: Dry mouth Not indicative of heat prostration, dry mouth is a common side effect of scopolamine rather than a direct symptom of overheating or heat-related illness.
C: Skin rash While skin rashes can result from various conditions, they do not specifically signify heat prostration and are not relevant to the body's thermoregulatory failure.
D: Urinary retention Although a potential side effect of scopolamine, urinary retention does not correlate with the symptoms of heat prostration and does not indicate overheating or heat stress.

Question 21
Regular
A client with a peptic ulcer visits a health care facility. The physician has prescribed belladonna as part of the treatment. Before administering this drug, the nurse would assess which of the following?
Correct!
Incorrect
The correct answer is: B
Rationale
B: The nurse would assess stools before administering belladonna because this medication can affect gastrointestinal motility and may lead to constipation, which is crucial to monitor in patients with peptic ulcers.
A: Saliva This assessment is less relevant as belladonna primarily influences bowel function, rather than salivary production, making it a secondary concern in peptic ulcer management.
C: Urine pH Although belladonna may have some effects on urinary function, monitoring urine pH does not directly relate to its impact on peptic ulcers or gastrointestinal health.
D: Blood glucose level While blood glucose levels are important, they have no direct correlation with the effects of belladonna on peptic ulcers, making this assessment unnecessary in this context.

Question 22
Regular
A nurse is administering a cholinergic blocking drug preoperatively to a client. What intervention should the nurse perform after administering the drug to the client?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Raise the side rails of the bed. After administering a cholinergic blocking drug, the nurse should ensure the client's safety by raising the side rails, minimizing the risk of falls due to potential drowsiness or dizziness.
A: Provide cold milk to the client. Offering cold milk does not address safety needs and may interfere with the client's ability to swallow properly after receiving the medication.
C: Tell the client to lie completely flat in bed. Advising the client to lie flat may increase discomfort or complications, especially if sedation occurs following drug administration.
D: Provide frequent sips of water. While hydration is important, frequent sips may not be suitable immediately after administration, as the medication could cause dry mouth or swallowing difficulties.

Question 23
Regular
A nurse is caring for a client who has been prescribed belladonna for the treatment of prolonged diarrhea. Which of the following nursing interventions should the nurse perform before administering the drug?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Assess weight of the client.
Monitoring the client's weight is essential before administering belladonna, as it may indicate dehydration or electrolyte imbalances due to prolonged diarrhea, helping the nurse determine the appropriateness of treatment.
A: Check stools of the client.
While stool assessment provides valuable information about diarrhea, it does not directly influence the immediate administration of belladonna, which primarily targets symptom relief rather than stool characteristics.
B: Monitor for abdominal pain.
Observing for abdominal pain can be relevant post-administration, but it does not serve as a prerequisite intervention before giving belladonna, which requires weight consideration instead.
D: Monitor vital signs every 2 hours.
Although important for overall patient assessment, routine vital sign checks do not specifically address the effects or requirements related to the administration of belladonna for prolonged diarrhea.

Question 24
Regular
A nurse is caring for a client receiving cholinergic blocking drug therapy. The client complains of a cotton-mouth feeling. Which of the following would be most appropriate?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Checking the oral cavity daily for soreness or ulcerations is the most appropriate action, as cholinergic blocking agents can lead to dry mouth, increasing the risk of oral complications. Regular inspection helps identify potential issues early and allows for timely interventions to maintain oral health.
A: Inspect the throat for signs of an infection. This option addresses a different concern and does not directly relate to the side effect of dry mouth associated with cholinergic drugs.
B: Suggest the client avoid ingesting water before taking the drug. This recommendation could exacerbate the cotton-mouth sensation rather than alleviate it, making it counterproductive for the client’s comfort.
D: Suggest the client avoid the use of ice or cold beverages. Cold beverages may provide temporary relief from dry mouth, so advising against them does not effectively address the client's discomfort.

Question 25
Regular
A client is experiencing photophobia secondary to the administration of a cholinergic blocking drug. Which of the following would be most appropriate?
Correct!
Incorrect
The correct answer is: B
Rationale
Limiting the use of overhead lights is the most appropriate action. This approach reduces glare and harsh lighting, creating a more comfortable environment for the client experiencing photophobia due to the cholinergic blocking drug's side effects.
A: Keeping the client's room brightly lit. Bright lighting exacerbates photophobia, increasing discomfort and strain on the eyes, which is counterproductive to alleviating the client's symptoms.
C: Encouraging the client to use sunscreen. Sunscreen is irrelevant for indoor photophobia and does not address the immediate discomfort caused by light sensitivity due to medication.
D: Suggesting the client avoid watching television. Avoiding television does not effectively mitigate photophobia; instead, adjusting lighting conditions is a more direct and beneficial strategy for managing symptoms.

Question 26
Regular
A client with motion sickness is prescribed transdermal scopolamine. The nurse would instruct the client to apply the patch at which frequency?
Correct!
Incorrect
The correct answer is: D
Rationale
The patch should be applied every 72 hours. This timing allows for the continuous release of scopolamine, providing effective management of motion sickness symptoms while minimizing potential side effects from more frequent applications.
A: Every 8 hours This frequency would result in excessive scopolamine exposure, increasing the risk of adverse effects and diminishing the patch's intended therapeutic efficacy.
B: Every 24 hours Applying the patch every 24 hours does not align with the recommended schedule for optimal drug delivery, potentially leading to inadequate symptom control for the client.
C: Every 48 hours Using the patch every 48 hours may not provide sufficient coverage for motion sickness symptoms, risking a decrease in therapeutic effectiveness and potentially leaving the client vulnerable.

Question 27
Multiple Choice
A nursing instructor is conducting a class for a group of nursing students about cholinergic blocking drugs. The instructor determines that the teaching was successful when the students identify which of the following as a cholinergic blocking drug used to treat Parkinson's disease?
Correct!
Incorrect
The correct answer is: C,D,E
Rationale
Cholinergic blocking drugs used to treat Parkinson's disease include Benztropine mesylate, Biperiden, and Trihexyphenidyl, which help alleviate symptoms by inhibiting excessive acetylcholine activity in the brain.
A: Fesoterodine Primarily functions as a bladder antispasmodic and does not have applications in managing Parkinson's disease symptoms or cholinergic blockade.
B: Trospium Used mainly for urinary incontinence; it does not address the neurological symptoms associated with Parkinson's disease or act as a cholinergic blocker.
D: Biperiden While recognized as a cholinergic blocker for Parkinson's, it is not the only option; thus, it's not exclusively considered for identification.
E: Trihexyphenidyl Also a valid cholinergic blocker for Parkinson's, but like Biperiden, it does not stand alone as the only correct answer.
