Question 1 of 5
A male client receives a scopolamine transdermal patch 2 hours before surgery. Four hours after surgery, the client tells the nurse that he is experiencing pain and asks why the patch is not working. Which action should the nurse take?
Correct Answer: B
Rationale: Scopolamine prevents postoperative nausea, not pain. Explaining its purpose clarifies the client’s misunderstanding. Placement checks, expired effects, or new patches do not address the pain, which requires separate analgesia.
Question 2 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: D
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 placebo effects, ineffectiveness, or burns.
Question 3 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 migraines, osteoarthritis, or diabetes.
Question 4 of 5
To control asthma, a client in a residential treatment facility uses a fluticasone propionate and salmeterol discus inhalation system, which provides an inhaled powdered form of these combined medications. Which instruction should the nurse provide to this client's caregivers?
Correct Answer: B
Rationale: Fluticasone/salmeterol is a maintenance therapy, not for acute asthma attacks, and should be used no more than twice daily to avoid side effects like oral thrush. Exhaling into the discus risks clumping the powder, and hypotension is not a common side effect.
Question 5 of 5
The healthcare provider prescribes magnesium sulfate 300 mg/hour IV. The IV bag contains magnesium sulfate 4 grams in dextrose 5% in water (D5W) 500 mL. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 37.5
Rationale: Convert 4 grams to 4000 mg. Infusion rate = (300 mg/hr) ÷ (4000 mg/500 mL) = 300 × 500 ÷ 4000 = 37.5 mL/hr. The pump should be set to 37.5 mL/hr.
