Question 1 of 5
The healthcare provider prescribes enoxaparin sodium 80 mg SUBQ twice daily. The nurse is preparing a preloaded 1 mL syringe labeled, 'Enoxaparin sodium injection, USP 60 mg/0.6 mL.' How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.8
Rationale: Desired dose = 80 mg, Concentration = 60 mg/0.6 mL = 100 mg/mL. Volume = 80 mg / 100 mg/mL = 0.8 mL.
Question 2 of 5
A client with cystitis receives a prescription for phenazopyridine. Which information should the nurse explain to the client about its therapeutic effect?
Correct Answer: A
Rationale: Phenazopyridine is a urinary analgesic that relieves pain, burning, and discomfort from irritated bladder mucosa in cystitis. It does not have antibacterial properties, calm spasms, or require specific timing related to sexual intercourse.
Question 3 of 5
The healthcare provider prescribes enoxaparin sodium 80 mg SUBQ twice daily. The nurse is preparing a preloaded 1 mL syringe labeled, 'Enoxaparin sodium injection, USP 60 mg/0.6 mL.' How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.8
Rationale: Desired dose = 80 mg, Concentration = 60 mg/0.6 mL = 100 mg/mL. Volume = 80 mg / 100 mg/mL = 0.8 mL.
Question 4 of 5
Ferrous sulfate elixir is prescribed for a client with iron deficiency anemia. Which instruction should the nurse provide this client about taking the liquid medication?
Correct Answer: A
Rationale: Using a straw prevents tooth staining from ferrous sulfate. Undiluted swallowing risks staining, antacids reduce absorption, and milk inhibits iron absorption due to calcium.
Question 5 of 5
Which laboratory value should the nurse review prior to administering the initial dose of a statin medication?
Correct Answer: A
Rationale: Statins can affect liver function, so reviewing serum liver enzymes is critical to monitor for hepatic adverse effects before initiation. CBC, electrolytes, and glucose are less directly related.
