When a patient is taking an adrenergic agonist drug, the nurse expects to observe which effect?

A.

Constricted pupils

B.

Increased heart rate

C.

Bronchial constriction

D.

Increased GI peristalsis

Answer and Explanation

The Correct Answer is B

A.    Constricted pupils: Adrenergic agonist drugs typically cause pupil dilation (mydriasis), not constriction.
B.    Increased heart rate: Adrenergic agonists stimulate the sympathetic nervous system, leading to increased heart rate (positive chronotropic effect) and increased cardiac contractility (positive
inotropic effect).

C.    Bronchial constriction: Adrenergic agonists typically cause bronchodilation, not constriction.

D.    Increased GI peristalsis: Adrenergic agonists usually inhibit GI motility, leading to decreased GI peristalsis and potentially constipation

Correct Answer is D

Explanation

A. "I know that I cannot switch brands of this medication." - This statement indicates an understanding of the importance of consistency in medication use. Phenytoin requires consistent dosing and should not be switched between different brands without consulting a healthcare provider.
B. "I have made an appointment to see my dentist next week." - This statement shows awareness of the need for dental care while taking phenytoin. Phenytoin can cause gum hyperplasia, so regular dental check-ups are recommended.

C. "I will notify my doctor before taking any other medications." - This statement demonstrates understanding of the potential for drug interactions with phenytoin. Phenytoin can interact with many other medications, so it's crucial to consult a doctor before starting any new medications.
D. "I'll be glad when I can stop taking this medicine." - This statement indicates a

misunderstanding about the management of epilepsy. Phenytoin is typically a long-term medication used to control seizures, and it's not usually discontinued unless directed by a healthcare provider. Further teaching is needed to address this misconception.

Correct Answer is ["A","C"]

Explanation

A. Increased heart rate: Sympathetic nervous system stimulation typically leads to increased heart rate as part of the "fight or flight" response.
B. Decrease in urinary bladder muscle tone: Sympathetic stimulation would typically cause relaxation of the urinary bladder, leading to increased muscle tone.
C. Increased blood pressure: Sympathetic nervous system activation results in vasoconstriction and increased cardiac output, leading to elevated blood pressure.
D. Decreased salivation: Sympathetic stimulation can lead to decreased salivation as part of the "fight or flight" response, but it's not a consistent finding.
E. Decreased bowel sounds: Sympathetic activation can inhibit gastrointestinal motility, leading to decreased bowel sounds, but it's not a universal finding in sympathetic stimulation.
