Question 2 of 5
The nurse is planning discharge teaching for a client with type 2 diabetes mellitus who has a new prescription for insulin glargine. Which action should the nurse plan to include in the discharge teaching?
Correct Answer: C
Rationale: Insulin glargine requires daily subcutaneous administration, so teaching self-injection skills is essential. It’s not dosed based on meal readings, adjusted for ketoacidosis, or used for hypoglycemia.
Question 3 of 5
A client who experiences migraine headaches reports having fewer headaches since using the herbal remedy feverfew. Which information is most important for the nurse to include in a teaching plan for this client?
Correct Answer: B
Rationale: Feverfew can cause allergic reactions in individuals allergic to chamomile, ragweed, or yarrow, making this critical to prevent serious reactions. Anxiety, GI effects, or NSAID interactions are less urgent.
Question 4 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 5 of 5
A client is scheduled for a spiral computed tomography (CT) scan with contrast to evaluate for pulmonary embolism. Which information in the client's history requires follow-up by the nurse?
Correct Answer: B
Rationale: Metformin use requires follow-up due to the risk of lactic acidosis with contrast agents affecting renal function. Metal prostheses, sobriety, and prior CT scans are less relevant to contrast administration safety.
