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 A
Explanation
A. "I should use my wrist to test the temperature of the water before bathing": This is correct as using the wrist to test water temperature helps prevent burns or injuries, which is crucial for individuals with diabetes who may have reduced sensation in their feet.
B. "I should put lotion between my toes every day to prevent dryness and cracking": This is incorrect because applying lotion between the toes can promote fungal infections. Lotion should be applied to the tops and soles of the feet, avoiding the spaces between the toes.
C. "I should apply a heating pad to my feet every night to help with circulation": This is incorrect as heating pads can cause burns due to decreased sensation. It is safer to avoid direct heat applications.
D. "I should round the corners of my toenails with a nail file to prevent ingrown nails": This is incorrect; toenails should be trimmed straight across to prevent ingrown nails rather than rounded.
Correct Answer is D
Explanation
A. "I should consume fish once per week": While consuming fish is beneficial, particularly fatty fish high in omega-3 fatty acids, this alone is not a comprehensive strategy for preventing hypertension.
B. "With a BMI of 30, I should focus on maintaining my current weight": With a BMI of 30, which is classified as obese, the focus should be on reducing weight rather than maintaining it to help prevent hypertension.
C. "I should exercise for 30 minutes three times per week": The recommended amount of exercise for cardiovascular health is at least 150 minutes of moderate-intensity exercise per week, which is more frequent than three times per week.
D. "I should consume no more than 2,000 milligrams of sodium per day": This is correct as reducing sodium intake to no more than 2,000 milligrams per day is a key strategy for preventing and managing hypertension.
