A nurse is caring for a client who has a new prescription for metformin. Which of the following laboratory results should the nurse evaluate prior to administering the first dose?
Potassium level
Creatinine level
Platelet count
Liver enzymes
The Correct Answer is B
Before administering the first dose of metformin, the nurse should evaluate the client's creatinine level. Metformin is primarily excreted by the kidneys, and its clearance from the body depends on the renal function. If the client has impaired kidney function, metformin can accumulate in the body and lead to potential adverse effects, particularly lactic acidosis.
Monitoring the creatinine level helps assess the client's kidney function and determines whether it is safe to administer metformin. If the creatinine level is elevated, indicating reduced kidney function, the nurse should consult with the healthcare provider to determine the appropriate dose adjustment or consider an alternative treatment option.
Let's go through the other options and explain why they are not the priority laboratory results to evaluate before administering metformin:
A. Potassium level: While monitoring potassium levels is important in some situations, it is not a primary concern before administering metformin. Metformin does not have a significant effect on potassium levels, and it is not a medication known for causing hypokalemia (low potassium levels).
C. Platelet count: Metformin does not have a direct impact on platelet count, and evaluating platelet count is not typically required before starting metformin therapy. Platelet count monitoring may be relevant for certain other medications or medical conditions, but it is not specific to metformin administration.
D. Liver enzymes: While it is essential to monitor liver function in clients on long-term metformin therapy, evaluating liver enzymes before the first dose of metformin is not the priority. Metformin is primarily cleared by the kidneys, and liver enzymes are not directly affected by its initial administration. However, ongoing monitoring of liver function may be necessary during long-term

Correct Answer is C
Explanation
The nurse should monitor the client receiving long-term treatment with oral doses of prednisone for the development of osteoporosis. Prednisone is a corticosteroid medication that can lead to decreased bone density and increase the risk of fractures. Prolonged use of prednisone can interfere with calcium absorption and increase bone resorption, leading to osteoporosis.
Hypoglycemia (A) is not a common adverse effect of prednisone. In fact, prednisone can cause hyperglycemia and increase the risk of developing diabetes.
Hyperreflexia (B) is not typically associated with prednisone use. Hyperreflexia is an exaggerated reflex response and is not a common adverse effect of corticosteroid therapy.
Inflammatory bowel disease (D) is not an adverse effect of prednisone. In fact, prednisone is often used as a treatment for inflammatory bowel disease to reduce inflammation and symptoms.
Therefore, the nurse should primarily monitor the client for the development of osteoporosis when receiving long-term treatment with oral doses of prednisone.
Correct Answer is ["200 mL\/h"]
Explanation
To determine the infusion rate in mL/h, we need to divide the total volume (100 mL) by the total time (30 minutes) and then convert the result to hours.
100 mL / 30 min = 3.33 mL/min
To convert minutes to hours, we multiply by 60:
3.33 mL/min * 60 min/h = 199.8 mL/h
Rounding to the nearest whole number, the nurse should set the IV infusion pump to deliver 200 mL/h.
