Extract:
Question 1 of 5
A nurse is caring for a patient who is receiving DSW with 20 mEq of KCL at 75 mL/hr. The provider has prescribed 1 g of ceftriaxone IV. When preparing to administer this medication by IV piggyback, which of the following data is the highest priority for the nurse to consider before administration?
Correct Answer: B
Rationale: Ensuring ceftriaxone compatibility with D5W and KCl prevents chemical reactions or precipitation, taking priority over vital signs, consciousness, or bag volume.
Question 2 of 5
A 22-year-old dialysis patient presents to the ER with chest pain and palpitations. Laboratory tests reveal a Potassium (K+) level of 7.0 mEq/L. Which electrolyte imbalance is the patient suffering from?
Correct Answer: B
Rationale: A potassium level of 7.0 mEq/L indicates hyperkalemia, causing cardiac symptoms, unlike calcium or sodium imbalances.
Question 3 of 5
A nurse is preparing to administer heparin subcutaneously to an obese client who has a deep vein thrombosis. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: A 90° angle suits obese clients' thicker subcutaneous tissue, unlike a larger gauge needle, massaging (risks bruising), or aspirating (unnecessary).
Question 4 of 5
If the nurse needs to administer a 2 mL injection what size syringe is most appropriate to use?
Correct Answer: A
Rationale: A 5 mL syringe accommodates 2 mL with extra space for accuracy, unlike 1 mL (too small), 10 mL (too large), or 3 mL (less optimal).
Question 5 of 5
A nurse is preparing to administer morphine 15 mg subcutaneously. The amount available is morphine injection 10 mg/mL. How many mL should the nurse administer?
