Question 1 of 5
The nurse is providing discharge instructions to a client who has been prescribed gabapentin 300 mg by mouth (PO) three times a day for postherpetic neuralgia. Which symptom should the nurse tell the client to report to the healthcare provider?
Correct Answer: B
Rationale: Rapid weight gain may indicate fluid retention or other complications, requiring provider evaluation, though not a common gabapentin side effect. Gastric irritation, sexual dysfunction, and photosensitivity are less associated with gabapentin and less urgent.
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 who is newly diagnosed with diabetes insipidus (DI) is receiving a synthetic vasopressin intravenously. Which side effect of vasopressin reported by the client should the nurse report to the healthcare provider?
Correct Answer: A
Rationale: Worsening headache may indicate water intoxication or hyponatremia from excessive vasopressin-induced water retention, requiring immediate provider notification. Polyuria, low specific gravity, and polydipsia are DI symptoms, not vasopressin side effects.
Question 4 of 5
Which intervention is most important for the nurse to implement for a client with type 2 diabetes mellitus (DM) who is receiving insulin lispro?
Correct Answer: B
Rationale: Insulin lispro, rapid-acting, peaks 1-2 hours post-dose, requiring meals shortly after administration to prevent hypoglycemia. Synchronizing meal timing with insulin is critical. Hypoglycemia checks, glucose sources, and monitoring are supportive but secondary.
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.
