Question 1 of 5
A drug for which research has shown an adverse effect in animals but not in pregnant women would be categorized as Category
Correct Answer: C
Rationale: Category C drugs show animal adverse effects (e.g., fetal harm) but lack human data, fitting this scenario-risk can't be ruled out. Category A is safe in humans. B has no animal or human risk. D has human risk evidence. C balances uncertainty, per FDA.
Question 2 of 5
A 30-year-old male patient who is treated with haloperidol for his diagnosis of schizophrenia is considered to be well-managed symptomatically for his psychotic symptoms. However, he is reporting restlessness, the inability to sit still at the dinner table, and his family notices that he is pacing up and down the hallway frequently. Of the following, which is the best medication to treat this antipsychotic-induced akathisia?
Correct Answer: E
Rationale: Haloperidol's D2 blockade causes akathisia—restlessness and pacing—as an EPS. Propranolol, a beta-blocker, reduces akathisia by modulating catecholamine activity, a first-line treatment per guidelines, unlike anticholinergics (benztropine) which target dystonia/parkinsonism. Dantrolene treats muscle spasticity, not akathisia. Amoxapine, an antidepressant, worsens psychosis. Bromocriptine, a dopamine agonist, risks psychosis exacerbation. Propranolol's efficacy, safety, and specificity for akathisia make it the best choice, replacing D as instructed.
Question 3 of 5
The patient is complaining of a severe headache. The physician orders aspirin. Which action by the nurse will result in the fastest relief of the patient's headache?
Correct Answer: D
Rationale: Aspirin on an empty stomach absorbs fastest, speeding headache relief by avoiding food delays-fatty meals like peanut butter slow gastric emptying, reducing onset. Alkaline foods may alter pH but don't hasten absorption significantly. Enteric-coated forms delay release for GI protection, not speed. Empty stomach delivery maximizes bioavailability quickly, aligning with pain relief urgency.
Question 4 of 5
A 21-year-old male college student presents to the emergency department with hives over his chest and arms. The history and physical exam reveals that he used a new laundry detergent and he was having an allergic reaction. The physician wants to prescribe an antihistamine that will not sedate the patient because he has to study for a test. What is the most appropriate treatment?
Correct Answer: D
Rationale: Allergic hives from detergent need a non-sedating antihistamine. Fexofenadine -blocks H1 receptors without drowsiness, ideal for studying. Chlorpheniramine , dimenhydrinate , and diphenhydramine sedate. Ipratropium (E) is irrelevant. Fexofenadine ensures efficacy and alertness.
Question 5 of 5
A patient will be receiving a thrombolytic drug as part of the treatment for acute myocardial infarction. The nurse explains to the patient that this drug is used for which purpose?
Correct Answer: C
Rationale: Thrombolytic drugs are used to dissolve blood clots (thrombi) that are causing blockages in blood vessels, such as the coronary arteries in the case of acute myocardial infarction (heart attack). By breaking down the clot, these drugs help to restore blood flow to the affected area, reducing damage to the heart muscle and improving the patient's prognosis. Thrombolytic therapy is time-sensitive and is most effective when administered soon after the onset of a heart attack to minimize the extent of heart muscle damage.
