Extract:
Question 1 of 5
A client who is taking dextroamphetamine-amphetamine extended-release tablets for attention deficit hyperactivity disorder (ADHD), reports about having difficulty sleeping at night. Which assessment is most important for the nurse to obtain?
Correct Answer: A
Rationale: The timing of dextroamphetamine-amphetamine administration is critical, as taking it late in the day can cause insomnia due to its stimulant effects. Assessing the dose timing helps identify if adjustments are needed to improve sleep, making it the most important initial assessment.
Question 2 of 5
A client with benign prostatic hyperplasia receives a new prescription of tamsulosin. Which intervention should the nurse perform to monitor for an adverse reaction?
Correct Answer: B
Rationale: Tamsulosin, an alpha-1 antagonist, can cause hypotension, especially when initiating treatment. Monitoring blood pressure is essential to detect significant drops that could lead to dizziness or fainting, ensuring client safety.
Question 3 of 5
A client receives a prescription for penicillin 2 million units IM. The available vial is labeled, '600,000 units/2 mL.' How many mL should the nurse administer? (Enter numeric value only.)
Correct Answer: 4
Rationale: Required dose: 2 million units. Concentration: 600,000 units/2 mL = 300,000 units/mL. Volume = 2 million units / 300,000 units/mL = 4 mL.
Question 4 of 5
A client with anemia secondary to chronic kidney disease (CKD) started a prescription for epoetin alfa two months ago. Which client finding best indicates that the medication is effective?
Correct Answer: D
Rationale: The most direct indicator of the effectiveness of epoetin alfa is an increase in hemoglobin levels. Epoetin alfa stimulates erythropoiesis, raising hemoglobin in clients with anemia due to CKD. Monitoring hemoglobin provides objective evidence of the medication’s efficacy, unlike subjective reports or dietary changes.
Question 5 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?
Correct Answer: C
Rationale: Sodium polystyrene sulfonate lowers potassium levels in hyperkalemia. A potassium level of 3.8 mEq/L within the normal range indicates the medication has effectively reduced elevated potassium, the primary goal in AKI management.
