A nurse is assessing a client who has pulmonary edema. Which of the following findings should the nurse expect?

A. Correct. A hemoglobin level of 14.9 g/dL indicates that the client has an adequate amount of oxygen-carrying capacity in the blood, which is the goal of blood transfusion therapy.

B. Incorrect. A WBC count of 12,000/mm3 is slightly elevated and may indicate an infection or inflammation, which are not related to blood transfusion therapy.

C. Incorrect. A potassium level of 48 mEq/L is dangerously high and may cause cardiac arrhythmias, muscle weakness, or paralysis. This is not an expected outcome of blood transfusion therapy and may indicate hemolysis or renal impairment.

D. Incorrect. A BUN level of 18 mg/dL is within the normal range and does not reflect the effectiveness of blood transfusion therapy.

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.
