Question 1

Type: MCMA

A patient’s heart rate is found to be 72 beats per minute and regular. The nurse evaluates which situation in the patient’s peripheral nervous system?

Note: Credit will be given only if all correct choices and no incorrect choices are selected.

Standard Text: Select all that apply.

1. The sympathetic system is in control.
2. The parasympathetic system is dominating.
3. Both parasympathetic and sympathetic systems are influencing cardiac status.
4. The autonomic nervous system is affecting cardiac status.
5. The somatic nervous system is affecting cardiac status.

Correct Answer: 2,3,4

Rationale 1: If the sympathetic system was in control, the heart rate would be accelerated.

Rationale 2: Restful cardiac response indicates that the primary input is from the parasympathetic system.

Rationale 3: These two systems work in tandem to regulate the cardiac response.

Rationale 4: Both the sympathetic and parasympathetic systems are part of the autonomic system.

Rationale 5: The somatic system is separate from the autonomic system.

 

Global Rationale: Restful cardiac response indicates that the primary input is from the parasympathetic system. These two systems work in tandem to regulate the cardiac response. Both the sympathetic and parasympathetic systems are part of the autonomic system. If the sympathetic system was in control, the heart rate would be accelerated. The somatic system is separate from the autonomic system.

Question 2

Type: MCMA

 

A nurse is reading about the development of drugs that inhibit the parasympathetic nervous system. The nurse would look for articles about which drug classes?

Note: Credit will be given only if all correct choices and no incorrect choices are selected.

Standard Text: Select all that apply.

1. Anticholinergics
2. Parasympathomimetics
3. Parasympatholytics
4. Cholinergics
5. Muscarinic blockers

Correct Answer: 1,3,5

Rationale 1: Anticholinergics inhibit the parasympathetic nervous system.

Rationale 2: Parasympathomimetic drugs stimulate the parasympathetic nervous system.

Rationale 3: Parasympatholytic drugs inhibit the parasympathetic nervous system.

Rationale 4: Cholinergic drugs stimulate the parasympathetic nervous system.

Rationale 5: Muscarinic blockers inhibit the parasympathetic nervous system.

 

Global Rationale: Anticholinergics, parasympatholytics, and muscarinic blockers inhibit the parasympathetic nervous system. : Parasympathomimetic drugs and cholinergic drugs stimulate the parasympathetic nervous system.

Question 4

Type: MCMA

 

A patient has been prescribed an oral drug containing atropine. The nurse would hold the drug and contact the prescriber if which patient statements are made?

Note: Credit will be given only if all correct choices and no incorrect choices are selected.

Standard Text: Select all that apply.

1. “I would like to wait a few minutes to take this as I just drank some aloe juice.”
2. “Can I take this at the same time as my procainamide?”
3. “I have had a headache this morning.”
4. “I am allergic to penicillin.”
5. “My gallbladder surgery is scheduled for next week.”

Correct Answer: 1,2

Rationale 1: Atropine should be used with caution in those who use aloe.

Rationale 2: There is a drug–drug interaction between atropine and procainamide.

Rationale 3: Headache does not prevent use of atropine.

Rationale 4: Allergy to penicillin does not prevent use of atropine.

Rationale 5: Gallbladder surgery for next week would not prevent use of atropine.

 

Global Rationale: Atropine should be used with caution in those who use aloe. There is a drug–drug interaction between atropine and procainamide. Headache, allergy to penicillin, and gallbladder surgery scheduled for next week do not prevent use of atropine.
