A patient is prescribed a drug that causes the selective stimulation of beta2 receptors. The nurse should assess the patient for what?

Hypoglycemia

Improved breathing

Tachycardia

Decreased pain

Answer and Explanation

The Correct Answer is B

Choice A rationale: Selective stimulation of beta2 receptors is less likely to cause hypoglycemia; beta1 receptors are more involved in glucose metabolism.
Choice B rationale: Beta2 receptors are primarily found in the bronchioles of the lungs, and their stimulation leads to improved breathing.
Choice C rationale: Tachycardia is more commonly associated with the selective stimulation of beta1 receptors.
Choice D rationale: Beta2 receptors are not typically involved in the modulation of pain perception.

Correct Answer is B

Explanation

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.

A. Increased speed of conduction and gluconeogenesis B. Bronchodilation and increased heart rate, contractility, and conduction C. Increased vasodilation and enhanced myocardial contractility D. Bronchoconstriction and increased heart rate

Correct Answer is B

Explanation

Choice A rationale: Epinephrine does increase the speed of conduction, but it does not significantly contribute to gluconeogenesis.
Choice B rationale: Epinephrine is used in cardiac arrest to increase heart rate, contractility, and conduction. In asthma, it causes bronchodilation.
Choice C rationale: While epinephrine can cause some vasodilation, it is not a primary indication for its use in cardiac arrest or status asthmaticus.
Choice D rationale: Epinephrine causes bronchodilation, not bronchoconstriction.
