A nurse is providing dietary teaching to a client about sources of protein. The nurse should identify which of the following foods are complete proteins?

Choice A reason: Creatinine 0.8 mg/dL is within the normal range (0.6-1.2), and it does not indicate fluid volume excess. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys. High creatinine levels can indicate kidney damage or impaired renal function.

Choice B reason: Hgb 15 g/dL is within the normal range (13-17 for men, 12-16 for women), and it does not indicate fluid volume excess. Hgb stands for hemoglobin, which is a protein in red blood cells that carries oxygen to the tissues. Low hemoglobin levels can indicate anemia, bleeding, or hemolysis.

Choice C reason: BUN 18 mg/dL is within the normal range (7-20), and it does not indicate fluid volume excess. BUN stands for blood urea nitrogen, which is a waste product of protein metabolism that is filtered by the kidneys. High BUN levels can indicate dehydration, kidney damage, or high protein intake.

Choice D reason: Sodium 149 mEq/L is high and indicates fluid volume excess. Sodium is an electrolyte that helps maintain fluid balance, blood pressure, and nerve impulses. High sodium levels can cause fluid retention, edema, hypertension, and heart failure.

Choice A reason: Increasing vitamin C intake while taking this medication is not necessary, as vitamin C does not interact with tetracycline. Vitamin C is important for immune function, wound healing, and collagen synthesis.

Choice B reason: Eliminating raw fruits and vegetables until 2 weeks after completing this medication is not required, as raw fruits and vegetables do not interfere with tetracycline. Raw fruits and vegetables are good sources of fiber, vitamins, minerals, and antioxidants.

Choice C reason: Taking a folic acid supplement while on this medication is not advised, as folic acid can reduce the absorption and effectiveness of tetracycline. Folic acid is essential for DNA synthesis, cell division, and red blood cell production.

Choice D reason: Avoiding taking this medication with milk products is important, as milk products contain calcium, which can bind to tetracycline and form insoluble complexes that decrease its absorption and activity. Milk products also increase the risk of gastrointestinal side effects such as nausea, vomiting, and diarrhea.
