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 D
Explanation
Choice A rationale: Methadone is an opioid analgesic and may exacerbate respiratory depression. It is not typically used as an antidote for opioid overdose.
Choice B rationale: Nalbuphine is a partial opioid agonist-antagonist and may have less respiratory depressant effect than pure opioid agonists. However, naloxone is the specific opioid antagonist used in opioid overdose situations.
Choice C rationale: Tramadol is an opioid analgesic and may exacerbate respiratory depression. It is not typically used as an antidote for opioid overdose.
Choice D rationale: Naloxone is the opioid antagonist used to reverse opioid- induced respiratory depression. It should be administered in the case of opioid overdose.
Correct Answer is D
Explanation
Choice A rationale: Temperature is not a priority assessment before the administration of metoprolol for chronic stable angina.
Choice B rationale: Urinary function is not a priority assessment before the administration of metoprolol for chronic stable angina.
Choice C rationale: Respiratory rate is not a priority assessment before the administration of metoprolol for chronic stable angina.
Choice D rationale: The priority assessment before the administration of metoprolol is the heart rate. Metoprolol is a beta-blocker that primarily affects the heart rate, so it is important to assess for bradycardia before administration.
