Question 1 of 5
The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective? Reference Range: Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)] Hemoglobin [14 to 18 g/dL (140 to 180 g/L)] Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)] Ammonia [10 to 80 μg/dL (6 to 47 μmol/L)]
Correct Answer: C
Rationale: Sodium polystyrene sulfonate lowers potassium by exchanging sodium for potassium in the gut. A potassium level of 3.8 mEq/L (normal range) indicates effective hyperkalemia treatment in AKI. Ammonia, hemoglobin, and glucose are unaffected by this medication.
Question 2 of 5
A client receives a prescription for allopurinol. Which information provided by the client requires additional instruction by the nurse?
Correct Answer: A
Rationale: Doubling a missed allopurinol dose risks toxicity and is incorrect; clients should take it as soon as remembered or skip it if near the next dose. Reducing caffeine/acidic intake, taking with food, and hydration are appropriate to manage uric acid and GI effects.
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: B
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
The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective? Reference Range: Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)] Hemoglobin [14 to 18 g/dL (140 to 180 g/L)] Potassium [3.5 to 5 mEq/L (3.5 to 5 mmol/L)] Ammonia [10 to 80 μg/dL (6 to 47 μmol/L)]
Correct Answer: C
Rationale: Sodium polystyrene sulfonate lowers potassium by exchanging sodium for potassium in the gut. A potassium level of 3.8 mEq/L (normal range) indicates effective hyperkalemia treatment in AKI. Ammonia, hemoglobin, and glucose are unaffected by this medication.
Question 5 of 5
After receiving the third dose of a new oral anticoagulant prescription, an older adult client develops bleeding and tender gums and has many new bruises. Which actions should the nurse implement? Select all that apply.
Correct Answer: B,C,D,E
Rationale: Bleeding and bruising suggest anticoagulant-related complications. Completing a variance report documents issues, reviewing coagulation labs guides management, reporting to the provider ensures intervention, and a soft toothbrush reduces gum trauma. NSAIDs increase bleeding risk and are contraindicated.
