A nurse is reviewing the ABG values of a client. The client has a pH of 7.2, PaCO2 of 60 mm Hg, and HCO3 of 25 mEq/L. The nurse should identify that the client has which of the following acid-base imbalances?

- A. This choice is incorrect because verapamil and TPN do not have a significant food and medication interaction. Verapamil is a calcium channel blocker that can lower blood pressure and heart rate, while TPN is a form of intravenous nutrition that provides calories, electrolytes, vitamins, and minerals. The nurse should monitor the client's vital signs and blood glucose levels, but there is no need to intervene to prevent an interaction.

- B. This choice is incorrect because phenytoin and milkshakes do not have a significant food and medication interaction. Phenytoin is an anticonvulsant that can decrease the absorption of some vitamins, such as folic acid and vitamin D, but milkshakes are not a major source of these nutrients. The nurse should encourage the client to eat a balanced diet and take supplements as prescribed, but there is no need to intervene to prevent an interaction.

- C. This choice is incorrect because potassium-rich foods and furosemide do not have a significant food and medication interaction. Furosemide is a loop diuretic that can cause hypokalemia, or low potassium levels, but potassium-rich foods can help prevent this complication. The nurse should monitor the client's electrolyte levels and fluid balance, but there is no need to intervene to prevent an interaction.

- D. This choice is correct because MAOIs and cheeseburgers have a significant food and medication interaction. MAOIs are antidepressants that can cause hypertensive crisis, or dangerously high blood pressure, if the client consumes foods that contain tyramine, such as aged cheeses, cured meats, fermented foods, and beer. The nurse should intervene to prevent the client from eating a cheeseburger and educate the client about avoiding tyramine-containing foods while taking MAOIs.

- A. Instructing the client about the importance of regular medical appointments is important but not the priority because it is a secondary prevention strategy that aims to detect and treat any complications or changes in the client's condition early. The client should have regular follow-up visits with an endocrinologist, a diabetes educator, an ophthalmologist, a podiatrist, a dentist, and other health care providers as needed.

- B. Encouraging the client to participate in daily exercise is important but not the priority because it is a tertiary prevention strategy that aims to reduce disability and improve quality of life for clients with chronic conditions. Exercise can help lower blood glucose levels, improve insulin sensitivity, reduce cardiovascular risk factors, enhance mood, and promote weight management for clients with type 1 diabetes mellitus. The client should consult with their health care provider before starting an exercise program and follow safety guidelines such as checking blood glucose levels before and after exercise, wearing appropriate footwear and clothing, carrying a source of fast-acting carbohydrate, and staying hydrated.

- C. Explaining proper foot care techniques to the client is important but not the priority because it is a tertiary prevention strategy that aims to prevent or minimize complications such as foot ulcers, infections, and amputations for clients with type 1 diabetes mellitus. Foot care includes inspecting feet daily for any injuries or abnormalities, washing feet with mild soap and warm water, drying feet thoroughly especially between toes, applying moisturizer to prevent dryness and cracking, trimming toenails straight across and filing edges smooth, wearing clean cotton socks and well-fitting shoes, avoiding walking barefoot or exposing feet to extreme temperatures or pressure, and seeking medical attention for any foot problems.

- D. Ensuring that the client understands the medication regimen is the nurse's priority because type 1 diabetes mellitus requires lifelong insulin therapy to maintain blood glucose levels within normal range and prevent complications such as ketoacidosis, hypoglycemia, and organ damage. The client needs to know how to administer insulin injections, monitor blood glucose levels, adjust insulin doses according to carbohydrate intake and physical activity, recognize and treat signs and symptoms of hypo- and hyperglycemia, and store insulin properly.
