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.) How many mL should the nurse administer?

Question 2 of 5
Before administering the initial dose of sumatriptan succinate to a client with a migraine headache, it is most important to determine if the client's history includes which problem? Which problem in the client's history is most important to determine?

Question 3 of 5
The nurse is reviewing the client’s laboratory results. Based on a client’s serum digoxin level, the client is diagnosed with digoxin toxicity. Which action should the nurse expect to implement? Which action should the nurse expect to implement?
Correct Answer: D
Rationale: Digoxin toxicity is often exacerbated by electrolyte imbalances, such as hypokalemia or hypercalcemia. Checking acid-base and electrolyte values identifies contributing factors, guiding appropriate interventions like withholding digoxin or correcting imbalances.
