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 1.3 mg/dL is slightly elevated, but 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: BNP 300 pg/mL is high and indicates fluid volume excess. BNP stands for brain natriuretic peptide, which is a hormone released by the heart when it is stretched by increased blood volume or pressure. High BNP levels can indicate heart failure or fluid overload.

Choice C reason: Potassium 3.5 mEq/L is within the normal range (3.5-5.0), and it does not indicate fluid volume excess. Potassium is an electrolyte that helps regulate nerve and muscle function, especially the heart. Low or high potassium levels can cause cardiac arrhythmias, muscle weakness, or paralysis.

Choice D reason: Sodium 140 mEq/L is within the normal range (135-145), and it does not indicate fluid volume excess. 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: Telling the client to lie down after eating can increase the risk of aspiration pneumonia, as food or liquids can enter the lungs more easily when lying down.

Choice B reason: Instructing the client to tuck her chin when swallowing can help prevent aspiration pneumonia, as it closes off the airway and directs food or liquids into the esophagus.

Choice C reason: Placing the client in a Fowler's position to eat can help prevent aspiration pneumonia, as it elevates the head and chest and allows gravity to assist with swallowing.

Choice D reason: Encouraging the client to drink water before each meal can increase the risk of aspiration pneumonia, as it can thin out saliva and make it harder to control swallowing.
