A healthcare professional is about to administer Propranolol to a patient. The healthcare professional takes the patient's apical pulse and documents it as 58 bpm. How should the healthcare professional proceed?

Correct Answer: D

Rationale: When a patient's apical pulse is 58 bpm, it is below the normal range. Propranolol is a beta-blocker that can further lower the heart rate. Therefore, it is crucial to withhold the medication and notify the healthcare provider to evaluate the patient's condition. Administering Propranolol in this situation can exacerbate bradycardia, leading to serious complications. Choosing to administer the medication as prescribed (Choice A) can put the patient at risk. Administering half of the normal dose (Choice B) without healthcare provider guidance is not appropriate in this case. Considering the extended-release form of the medication (Choice C) does not address the immediate concern of bradycardia and is not the best course of action.

Correct Answer: B

Rationale: The correct antidote for Warfarin is Vitamin K. Warfarin works by inhibiting vitamin K-dependent clotting factors. Administering Vitamin K helps reverse its effects by replenishing these factors. Choices A, C, and D are incorrect. Naloxone is used to reverse opioid overdose, Glucagon is used to treat severe low blood sugar, and Vitamin B is not the antidote for Warfarin.

Correct Answer: A

Rationale: The correct answer is A: Bronchodilation. Albuterol is primarily used for bronchodilation, where it relaxes the muscles in the airways to make breathing easier. This medication is commonly prescribed for conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory conditions where bronchodilation is beneficial. Choices B, C, and D are incorrect because Albuterol is not used as an anti-coagulant, anti-arrhythmic, or proton-pump inhibitor.

Correct Answer: C

Rationale: Flumazenil is the specific antidote used to reverse the effects of Alprazolam. Alprazolam is a benzodiazepine, and Flumazenil is a benzodiazepine receptor antagonist that works by competitively inhibiting the actions of benzodiazepines at the receptor site, effectively reversing their sedative and other effects. Physostigmine is not used as an antidote for benzodiazepine overdose and can have significant side effects. Protamine sulfate is used to reverse the effects of heparin, not benzodiazepines like Alprazolam. Acetylcysteine is used as an antidote for acetaminophen overdose, not benzodiazepines like Alprazolam.

Correct Answer: A

Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.
