Question 1 of 5
The home health nurse observes a client self-administering an epinephrine injection using an auto-injector pen. Which client action requires intervention by the nurse?
Correct Answer: C
Rationale: Epinephrine auto-injectors are single-use devices. Cleansing for reuse risks contamination or malfunction, requiring intervention. Holding the pen in place ensures full dose delivery, the thigh is the correct site, and injecting through clothing is acceptable in emergencies.
Question 2 of 5
A client receives a prescription for penicillin G 1,000,000 units intramuscular (IM) daily. The medication is available in 1,200,000 units/2 mL syringe. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 1.7
Rationale: Calculate: (1,000,000 units ÷ 1,200,000 units) × 2 mL = 1.67 mL, rounded to 1.7 mL. This ensures the correct dose of penicillin G is administered intramuscularly.
Question 3 of 5
The nurse is assessing a client who was recently diagnosed with Parkinson’s disease and is taking carbidopa-levodopa. The client is concerned that the medication is not working. Which intervention should the nurse implement first?
Correct Answer: D
Rationale: Clarifying the client’s concern about carbidopa-levodopa’s effectiveness guides targeted assessment. Urine color, dyskinesia, or meal timing are secondary until the specific issue is understood.
Question 4 of 5
On admission, the healthcare provider prescribes a broad spectrum antibiotic for a client with a gram-negative infection. Before administering the first dose, it is most important for the nurse to implement which prescription?
Correct Answer: C
Rationale: Obtaining cultures before antibiotics ensures identification of the pathogen and its sensitivities, guiding effective therapy.
Topical antibiotics, fluid monitoring, or lab tests are secondary.
Question 5 of 5
The nurse administers the initial dose of cefoxitin to a client whose medical record indicates an allergy to penicillin. Which finding is most important for the nurse to report to the healthcare provider?
Correct Answer: B
Rationale: Pruritis and rash suggest a possible allergic reaction to cefoxitin, a cephalosporin, due to cross-reactivity with penicillin. This requires immediate reporting. Renal output, GI symptoms, and vaginal discharge are less specific to allergic responses.
