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.

Correct Answer is C
Explanation
A. "I will increase vitamin C intake by drinking orange juice": This is incorrect because citrus juices like orange juice can exacerbate GERD symptoms by increasing acid production.
B. "I will lie down for 30 minutes after each meal": This is incorrect as lying down after eating can increase the risk of acid reflux. Clients should remain upright for at least 2-3 hours after eating.
C. "I will eat six small meals each day": This is correct because eating smaller, more frequent meals can help reduce the frequency of GERD symptoms by decreasing stomach pressure and acid production.
D. "I will sleep flat on my back at night": This is incorrect as sleeping flat can worsen GERD symptoms. Elevating the head of the bed can help prevent acid reflux during sleep.
Correct Answer is B
Explanation
A. Orthopnea: This is more commonly associated with left-sided heart failure, where fluid accumulation in the lungs causes difficulty breathing when lying flat.
B. Lower-extremity edema: This is correct as right-sided heart failure often leads to fluid retention in the body, resulting in swelling of the lower extremities.
C. Clammy skin: This is not a typical finding specific to right-sided heart failure and may be seen in other conditions or complications.
D. Pink, frothy sputum: This is characteristic of left-sided heart failure and pulmonary edema, not right-sided heart failure.
