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:
To calculate: (2,000,000 units prescribed) ÷ (600,000 units/2 mL) = 2,000,000 × 2 ÷ 600,000 = 4 mL. The nurse should administer 4 mL to deliver the prescribed 2 million units.
Question 2 of 5
A client with generalized anxiety disorder (GAD) receives a new prescription for lorazepam. Which statement provided by the client requires additional instruction by the nurse?
Correct Answer: C
Rationale: Lorazepam may take time for optimal effect, and stopping abruptly risks withdrawal or worsening anxiety. Clients should continue as prescribed and consult their provider if effects are lacking. Relaxation techniques, avoiding sedatives, and moving slowly are appropriate.
Question 3 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: D
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 4 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: C
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 5 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 blocker, can cause orthostatic hypotension, risking dizziness or fainting. Monitoring blood pressure detects this adverse reaction. Urine output, weights, or bladder scans assess BPH symptoms, not tamsulosin’s side effects.
