Question 1 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? Which information in the client’s history requires follow up by the nurse?
Correct Answer: B
Rationale: Metformin can increase the risk of lactic acidosis when combined with iodinated contrast media, especially if renal function is compromised. Follow-up is needed to consider temporarily discontinuing metformin before and after the CT scan to prevent this serious complication.
Question 2 of 5
A client with bulimia and depression who is taking phenelzine 90 mg daily is admitted to an acute care hospital for uncontrolled hypertension. Which dietary choices should the nurse instruct the client to avoid? Which dietary choices should the nurse instruct the client to avoid?
Correct Answer: C
Rationale: Phenelzine, an MAOI, can cause hypertensive crisis if combined with tyramine-rich foods like pepperoni. Instructing the client to avoid pepperoni pizza prevents this dangerous interaction, especially given the client’s uncontrolled hypertension.
Question 3 of 5
The nurse is administering subcutaneous enoxaparin to a client following knee replacement surgery to prevent a deep vein thrombosis. Which laboratory result requires immediate action by the nurse? Which laboratory result requires immediate action by the nurse?
Correct Answer: B
Rationale: A platelet count of 100,000/mm3 indicates thrombocytopenia, increasing bleeding risk with enoxaparin, an anticoagulant. Immediate action, such as notifying the provider, is needed to prevent hemorrhage.
Question 4 of 5
The nurse is planning discharge teaching for a client with type 2 diabetes mellitus (DM) who has a new prescription for insulin glargine. Which action should the nurse plan to include in the discharge teaching? Which action should the nurse plan to include in the discharge teaching?
Correct Answer: B
Rationale: Insulin glargine is a long-acting insulin requiring daily subcutaneous administration. Teaching self-injection skills, including proper technique, site rotation, and storage, is essential for effective diabetes management and client independence.
Question 5 of 5
A client receives a prescription for a secondary infusion of IV erythromycin 1 gram in 200 mL dextrose 5% in water (D5W) to be infused in 90 minutes. The nurse should program the infusion pump to deliver how many mL/hour? (Enter the numerical value only. If rounding is required, round to the nearest whole number.) The nurse should program the infusion pump to deliver how many mL/hour?
Correct Answer: 133
Rationale: Volume = 200 mL; time = 90 minutes = 1.5 hours; infusion rate = 200 mL ÷ 1.5 hours = 133.33 mL/hr, rounded to 133 mL/hr.
