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.

Answer to Question 1

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.

Answer to Question 2

3
Rationale 1: Weight loss is the desired effect, and weight gain should not occur.
Rationale 2: Tachycardia when dehydrated is the cardiac system's response to fluid loss.
Rationale 3: Hypotension results from large amounts of fluid being excreted.
Rationale 4: Vomiting is not a common adverse effect.
Global Rationale: Loop diuretics can produce dehydration and electrolyte imbalances. Signs of dehydration include thirst, dry mouth, weight loss, and headache. Hypotension, dizziness, and fainting can result from the rapid fluid loss. Tachycardia when dehydrated is the cardiac system's response to fluid loss. Vomiting is not a common adverse effect.
