Question 1 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 2 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.
Question 3 of 5
Which nursing intervention has priority when initiating a continuous epidural infusion with an opioid analgesic?
Correct Answer: A
Rationale: Opioid analgesics via epidural infusion can cause respiratory depression, a life-threatening risk. Applying a pulse oximeter to monitor oxygen saturation is the priority to detect early signs of respiratory compromise, ensuring client safety over other interventions.
Question 4 of 5
A client with eczema receives a prescription for betamethasone cream. Which client statement indicates to the nurse that further teaching is needed?
Correct Answer: B
Rationale: Covering the site with an occlusive dressing can increase betamethasone absorption and side effects, and should only be done under specific medical guidance. This statement requires further teaching to ensure safe use.
Question 5 of 5
The nurse is providing discharge instructions to a client who has been prescribed an inhaled medication. Which statement provided by the client indicates a correct understanding of the instructions?
Correct Answer: A
Rationale: Rinsing the mouth after using an inhaled medication, especially corticosteroids, prevents oral thrush and other side effects. This indicates correct understanding, unlike using the inhaler during meals, limiting caffeine, or fixed bedtime use, which are not universally appropriate.
