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
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 A
Explanation
Choice A rationale: Respiratory depression can occur and persist for hours after the removal of a fentanyl patch. It is crucial to monitor respiratory status closely and be aware of the potential delayed onset of respiratory depression.
Choice B rationale: Fentanyl, like any opioid, carries risks, and safety precautions should be observed. However, it is not completely without risks, especially in certain populations or situations.
Choice C rationale: Using a heating pad with a fentanyl patch is not recommended, as it can increase drug absorption and the risk of overdose.
Choice D rationale: Fentanyl patches have a delayed onset of action, and the patient will not experience immediate pain relief. It may take several hours for the full effect to be achieved after the application of the patch.
