A nurse is preparing to measure a post-meal blood glucose level in a patient with diabetes mellitus. What steps should the nurse take?

Prick the central tip of the patient’s finger.

Apply the first drop of blood to the test strip.

Hold the patient’s finger in a dependent position.

Clean the patient’s finger with hexachlorophene.

Answer and Explanation

The Correct Answer is C

A. Prick the central tip of the patient’s finger: The central tip of the finger has more nerve endings, making it more painful. Instead, the side of the fingertip should be used because it has fewer nerve endings and promotes better blood flow.

B. Apply the first drop of blood to the test strip: The first drop of blood may contain interstitial fluid or contaminants (e.g., alcohol residue), leading to inaccurate readings. Instead, the first drop should be wiped away, and the second drop should be used for testing.

C. Hold the patient’s finger in a dependent position: Holding the finger in a dependent position (below heart level) helps increase blood flow to the fingertip, making it easier to obtain an adequate blood sample without excessive squeezing, which could dilute the sample with tissue fluid.

D. Clean the patient’s finger with hexachlorophene: Hexachlorophene is not recommended for skin antisepsis before blood glucose testing. Instead, alcohol wipes or soap and water should be used. The finger should be fully dried before pricking to avoid dilution of the blood sample.

Correct Answer is C

Explanation

Choice A rationale

Storing extra blankets in a box on the steps is not a safe practice for a client who has just returned home after a total hip arthroplasty. This could increase the risk of falls, which is a major concern after hip surgery.

Choice B rationale

Keeping pot handles turned towards the edge of the stove is not a safe practice. It increases the risk of spills and burns. Pot handles should always be turned towards the back of the stove to prevent accidents.

Choice C rationale

Placing electrical cords against the wall is a safe practice. It reduces the risk of tripping over the cords, which is especially important for a client who is recovering from a total hip arthroplasty.

Choice D rationale

Placing a throw rug next to the bathtub is not a safe practice. Throw rugs can easily slip and cause falls. A non-slip mat should be used instead.

A. The patient enjoys a glass of red wine every evening. B. The patient walks 3.2 km (2 mi) daily. C. The patient is lactose intolerant. D. The patient is a gardener.

Correct Answer is C

Explanation

Choice A rationale

Enjoying a glass of red wine every evening is not directly linked to an increased risk of osteoporosis. While excessive alcohol consumption can contribute to bone loss, moderate consumption (up to one drink per day for women and up to two drinks per day for men) does not appear to significantly affect bone mineral density.

Choice B rationale

Regular physical activity, such as walking, is actually beneficial for bone health. Weight-bearing exercises, including walking, can help increase bone density and reduce the risk of osteoporosis.

Choice C rationale

Lactose intolerance can increase the risk of osteoporosis. Individuals with lactose intolerance often avoid dairy products, which are a major source of dietary calcium. Calcium is essential for bone health, and inadequate calcium intake can lead to decreased bone density and an increased risk of osteoporosis.

Choice D rationale

Gardening is a form of physical activity, and like walking, it can help increase bone density and reduce the risk of osteoporosis. There is no evidence to suggest that gardening increases the risk of osteoporosis.
