RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 of 5
The home health nurse observes that a female client is using a topical preparation that contains echinacea to treat a canker sore. Her husband expresses concern regarding the effectiveness and safety of using herbs. How should the nurse respond?
Correct Answer: C
Rationale: Echinacea may have immune-boosting properties, potentially aiding canker sore treatment, though evidence is mixed. This response balances its possible benefits without dismissing its use, unlike suggesting burns, ineffectiveness, or placebo effects.
Question 2 of 5
Which action should the nurse implement to assess the effectiveness of amlodipine?
Correct Answer: A
Rationale: Amlodipine, a calcium channel blocker, lowers blood pressure to manage hypertension. Measuring blood pressure directly assesses its effectiveness. Calcium levels, electrolytes, or intake/output are not primary indicators of amlodipine’s therapeutic effect.
Question 3 of 5
The nurse is teaching a client who has been diagnosed with human immunodeficiency virus (HIV) about the antiretroviral medication regimen. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: C
Rationale: Antiretrovirals reduce viral load and transmission risk but do not fully prevent HIV transmission; safe practices are still needed. The other statements are accurate regarding HIV management and ART benefits.
Question 4 of 5
A client has a new prescription for diclofenac, a nonsteroidal anti-inflammatory drug (NSAID). Which information in the client's history is of greatest concern to the nurse in monitoring the client's response to this medication?
Correct Answer: B
Rationale: Chronic alcoholism increases the risk of gastrointestinal bleeding or ulcers with diclofenac, an NSAID, due to mucosal irritation. This history requires vigilant monitoring for GI symptoms, making it the greatest concern over osteoarthritis, diabetes, or migraines.
Question 5 of 5
The nurse is caring for an adult client who is taking digoxin. Which laboratory value should be reported to the healthcare provider immediately? Reference Range: Sodium [Adult 136 to 145 mEq/L (136 to 145 mmol/L)] Digoxin level [0.8 to 2.0 ng/mL (0.6 to 13 nmol/L)] Potassium (K+) [Adult: 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L)] Creatinine [0.5 to 1.1 mg/dL (44 to 97 μmol/L)]
Correct Answer: C
Rationale: Hypokalemia (3.2 mEq/L) increases digoxin toxicity risk, potentially causing arrhythmias. Immediate reporting allows potassium correction. Mild hyponatremia, normal creatinine, and therapeutic digoxin levels are less urgent.
