A patient is mowing his lawn on a hot Saturday afternoon. He begins to notice chest pain. What should his first action be?

Correct Answer: B

Rationale: The patient's first action should be to stop mowing and sit or lie down. Chest pain can be a symptom of a heart attack, and it is important for the patient to immediately rest and avoid physical strain. Continuing to mow the lawn could worsen the condition or lead to further complications. Sitting or lying down will help reduce the heart's workload and minimize the exertion on the body. If the chest pain continues or worsens, seeking medical help should be the next course of action.

Correct Answer: D

Rationale: A low apical pulse rate of 53 beats/min indicates bradycardia, which is a side effect of digoxin. Before administering digoxin, the nurse should always check the patient's pulse rate. If the apical pulse is below the facility's specified parameters (typically below 60 beats/min), the nurse should withhold the dose and notify the prescriber immediately. Bradycardia can be an indication of digoxin toxicity, which can be potentially life-threatening, so it is crucial to follow the protocol and seek further guidance before administering the medication.

Correct Answer: C

Rationale: Physostigmine is the antidote for Atropine overdose. Atropine is an anticholinergic drug that blocks the action of acetylcholine. Physostigmine works by increasing the levels of acetylcholine in the body, counteracting the effects of Atropine. It can help reverse the side effects of Atropine overdose, such as dry mouth, tachycardia, and drowsiness. Flumazenil is the antidote for benzodiazepines, Naloxone is the antidote for opioids, and Protamine sulfate is the antidote for heparin.

Correct Answer: B

Rationale: Bromocriptine, a dopamine D2 agonist used in Parkinson's, has ergot alkaloid properties, which can cause vasospasm by stimulating vascular smooth muscle receptors, occasionally leading to Raynaud's-like symptoms or digital ischemia. Amantadine, an NMDA antagonist, enhances dopamine release but lacks vasoconstrictive effects. Carbidopa inhibits dopa decarboxylase, aiding levodopa delivery without vascular impact. Entacapone, a COMT inhibitor, extends levodopa's duration but doesn't affect vessels. Ropinirole, a non-ergot agonist, avoids vasospasm. Bromocriptine's ergot-derived vasoconstriction, though rare, distinguishes it among antiparkinsonian drugs, requiring caution in patients with vascular risks.

Correct Answer: B

Rationale: Insulin glargine, a long-acting basal insulin, provides steady glucose control without a peak. Mixing it with regular insulin is incorrect'glargine's pH precipitates if combined, altering its action, indicating a teaching need. Same-time injection ensures consistency. Overnight control and no peak align with its 24-hour, flat profile. The misconception about mixing risks erratic glucose levels, critical in type 2 diabetes where stability is key. Further teaching must clarify glargine's unique formulation, preventing administration errors that could lead to hypo- or hyperglycemia, making B the statement requiring correction.
