A nurse teaches a patient who takes daily low-dose aspirin for protection against myocardial infarction and stroke to avoid also taking which medication?
Diphenhydramine [Benadryl]
Loratadine [Claritin]
Ibuprofen [Motrin]
Multivitamin
The Correct Answer is C
Choice A reason: Diphenhydramine, an antihistamine, does not significantly interact with aspirin’s antiplatelet effects. It primarily blocks histamine receptors, affecting allergies, not platelet aggregation. While it may cause drowsiness, it doesn’t increase bleeding risk or counteract aspirin’s cardiovascular benefits, making it safe to use concurrently with low-dose aspirin.
Choice B reason: Loratadine, a second-generation antihistamine, targets histamine receptors to relieve allergy symptoms. It has no known interaction with aspirin’s antiplatelet mechanism or bleeding risk. Its minimal side effect profile makes it compatible with low-dose aspirin for cardiovascular protection, so avoiding it is unnecessary in this context.
Choice C reason: Ibuprofen, an NSAID, competes with aspirin for COX-1 binding sites, reducing aspirin’s antiplatelet effect critical for preventing myocardial infarction and stroke. It also increases gastrointestinal bleeding risk when combined with aspirin, making it contraindicated for patients on low-dose aspirin therapy, thus the correct choice to avoid.
Choice D reason: Multivitamins do not interfere with aspirin’s antiplatelet action or increase bleeding risk. They provide supplemental nutrients without affecting COX-1 inhibition or platelet aggregation. There’s no pharmacological basis for avoiding multivitamins with low-dose aspirin, making this choice irrelevant for the patient’s cardiovascular regimen.

Correct Answer is ["C","E"]
Explanation
Choice A reason: Verapamil is not used for preterm labor; calcium channel blockers like nifedipine are preferred. Verapamil targets cardiovascular conditions, so this is incorrect for its therapeutic use.
Choice B reason: Verapamil is contraindicated in heart block, as it slows conduction. It is used for hypertension and dysrhythmias, not conduction blocks, so this is incorrect.
Choice C reason: Verapamil is a channel blocker used for essential hypertension, effectively reducing blood pressure by relaxing vessels. This is a standard use, making it a correct choice.
Choice D reason: Hypocalcemia is not treated with verapamil; it may worsen with calcium channel blockers. Cardiovascular indications are primary, so this is incorrect.
Choice E reason: Verapamil is used for cardiac dysrhythmias, such as supraventricular tachycardia, by slowing heart rate. This is a recognized indication, making it a correct choice.
Correct Answer is C
Explanation
Choice A reason: Theophylline is rarely used due to toxicity risks and less efficacy compared to beta-agonists. Increasing fluticasone dose doesn’t address acute exacerbations, as inhaled corticosteroids act slowly. Oxygen is appropriate, but this regimen lacks rapid-acting bronchodilators, making it inadequate for acute asthma management.
Choice B reason: Four puffs of albuterol via inhaler may be insufficient for severe asthma (90% saturation, wheezes). Theophylline is outdated, and nebulized treatments are more effective in emergencies. Oxygen is needed, but this combination lacks systemic steroids for inflammation, making it less optimal.
Choice C reason: Intravenous glucocorticoids reduce airway inflammation rapidly, nebulized albuterol and ipratropium provide synergistic bronchodilation, and oxygen corrects hypoxia (90% saturation). This aligns with guidelines for acute asthma exacerbations, addressing inflammation, bronchoconstriction, and oxygenation, making it the correct and comprehensive treatment choice.
Choice D reason: Intramuscular glucocorticoids are slower than intravenous for acute asthma. Salmeterol, a long-acting beta-agonist, is inappropriate for acute exacerbations, as it lacks rapid onset. Oxygen is needed, but this regimen doesn’t address immediate bronchoconstriction effectively, making it incorrect for emergency management.
