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?
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 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.
2. 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?
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 3: Parasympatholytic drugs inhibit the parasympathetic nervous system.
Rationale 5: Muscarinic blockers inhibit the parasympathetic nervous system.
