A nurse is preparing to obtain a postprandial blood glucose level from a client who has diabetes mellitus. Which of the following actions should the nurse take?
Clean the client's finger with hexachlorophene.
Apply the first drop of blood to the test strip.
Hold the client's finger in a dependent position.
Prick the central tip of the client's finger.
The Correct Answer is C
A. Clean the client's finger with hexachlorophene: Hexachlorophene is not recommended for cleaning the skin before blood glucose testing; a mild soap and water or an alcohol swab is typically used.
B. Apply the first drop of blood to the test strip: The first drop of blood is often not used due to potential contamination; the nurse should usually wipe away the first drop and use the second one.
C. Hold the client's finger in a dependent position: This is correct as holding the finger downward can help increase blood flow to the fingertip, facilitating easier blood collection.
D. Prick the central tip of the client's finger: Pricking the central tip can be painful; the sides of the fingertip are preferred for less discomfort and to avoid nerve endings.

B. Beef bouillon with crackers: Beef bouillon is high in sodium, which can elevate blood pressure, making it an unsuitable choice for someone with hypertension.
C. A ham sandwich on rye bread: Ham is high in sodium, and consuming it can negatively impact blood pressure control.
