A pre-op patient receives Atropine before induction of anesthesia. The nurse caring for this patient understands that this used to prevent?

Anxiety

Bradycardia

Dry mouth

Hypertension

Answer and Explanation

The Correct Answer is B

Choice A rationale: Atropine is not primarily used to prevent anxiety. Its main use is to increase heart rate by blocking vagal effects on the heart.
Choice B rationale: Atropine is commonly used to prevent or treat bradycardia, particularly during anesthesia induction, when vagal stimulation can lead to significant slowing of the heart rate.
Choice C rationale: Dry mouth is a common side effect of atropine, not its primary use. Atropine is not given to prevent dry mouth.
Choice D rationale: Atropine is not used to prevent hypertension. Its primary cardiovascular effect is to increase heart rate.

Correct Answer is C

Explanation

Choice A rationale: While a decreased frequency of migraine headaches is a positive outcome, it does not directly indicate the immediate therapeutic effect of a sumatriptan (a serotonin receptor agonist). It may suggest a preventive effect over time.
Choice B rationale: Complete absence of migraine headaches is a positive outcome, but it is not always achievable. Immediate cessation of all headaches might not be realistic with every dose.
Choice C rationale: This is correct. Sumatriptan, a serotonin receptor agonist, is designed to terminate or relieve an ongoing migraine headache when administered during an attack. The patient reporting the termination of the migraine headache after drug administration suggests the desired therapeutic effect.
Choice D rationale: Increased nausea is not a desired therapeutic effect of sumatriptan. Sumatriptan is used to relieve the symptoms of migraines, including nausea, not exacerbate them.

A. Decreased blood pressure, Uterine muscle relaxation B. Increased blood pressure, Contraction of skeletal muscle C. Increased Blood Pressure, Improved renal perfusion D. Decreased Blood Pressure, Decreased piloerection

Correct Answer is C

Explanation

Choice A rationale: Dopamine receptor activation is not associated with uterine muscle relaxation. It is more commonly associated with increased blood pressure.
Choice B rationale: Dopamine receptor activation is not associated with the contraction of skeletal muscle.
Choice C rationale: Activation of dopamine receptors is associated with increased blood pressure and improved renal perfusion.
Choice D rationale: Dopamine receptor activation is not associated with decreased piloerection.
