A nurse is reviewing the laboratory reports of a client who is undergoing nutritional screening due to a risk for chronic kidney disease. The nurse should identify that which of the following results indicates the need for further assessment?
Serum creatinine 3.5 mg/dL
Hematocrit 45%
Blood urea nitrogen 18 mg/dL
Sodium 140 mEq/L
The Correct Answer is A
Choice A reason: Serum creatinine 3.5 mg/dL is high and indicates the need for further assessment. 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: Hematocrit 45% is within the normal range (37-47% for women, 40-50% for men), and it does not indicate the need for further assessment. Hematocrit is the percentage of red blood cells in the blood. Low hematocrit levels can indicate anemia, bleeding, or hemolysis.
Choice C reason: Blood urea nitrogen 18 mg/dL is within the normal range (7-20), and it does not indicate the need for further assessment. Blood urea nitrogen is a waste product of protein metabolism that is filtered by the kidneys. High blood urea nitrogen levels can indicate dehydration, kidney damage, or high protein intake.
Choice D reason: Sodium 140 mEq/L is within the normal range (135-145), and it does not indicate the need for further assessment. Sodium is an electrolyte that helps maintain fluid balance, blood pressure, and nerve impulses. Low or high sodium levels can cause confusion, seizures, or coma.

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.
