A nurse is obtaining a capillary blood specimen to measure a client's blood glucose. Which of the following actions should the nurse take?

Allow the antiseptic to dry before puncturing.

Apply sterile gloves.

Hold the lancet at a 45° angle.

Massage the client's finger away from the puncture site.

Answer and Explanation

The Correct Answer is A

A. Allow the antiseptic to dry before puncturing.: This is correct. It is important to allow the antiseptic (such as alcohol) to dry before puncturing the skin. If the antiseptic is not allowed to dry, it can cause hemolysis of the blood sample and lead to inaccurate glucose readings.

B. Apply sterile gloves.: This is incorrect. While gloves should be worn to maintain hygiene and safety, non-sterile gloves are sufficient for a capillary blood glucose test. Sterile gloves are not necessary unless the procedure requires aseptic technique.

C. Hold the lancet at a 45° angle.: This is incorrect. The lancet should be held at a 90° angle to the skin to ensure a proper and clean puncture.

D. Massage the client's finger away from the puncture site.: This is incorrect. The finger should not be massaged before or after the puncture site because it can cause tissue damage and lead to inaccurate blood samples due to the mixing of interstitial fluid with the blood sample.

Correct Answer is B

Explanation

A. Store the dentures in a dry denture cup on the bedside table after cleaning.: Dentures should not be stored in a dry cup as this can lead to drying out and warping of the dentures. They should be stored in water or a denture solution to keep them moist.

B. Place a towel in the sink when cleaning the dentures.: This is correct. Placing a towel in the sink is a safety precaution to prevent dentures from breaking if they are accidentally dropped while being cleaned. It also helps prevent damage from impact with hard surfaces.

C. Remove the lower dentures before the upper dentures.: There is no specific order required for removing dentures, as both upper and lower dentures should be removed carefully and cleaned.

D. Use a circular motion to cleanse the biting surface of the dentures.: A circular motion is not the best technique for cleaning dentures. Instead, the dentures should be brushed gently with a soft toothbrush, focusing on cleaning all surfaces, including the biting surfaces, using a back-and-forth motion.

A. "You can take a stool softener to prevent constipation." B. "You can remove your eye patch during the day." C. "You should bend from the waist to pick up objects." D. "You can apply a warm, moist compress to your forehead to reduce pain."

Correct Answer is A

Explanation

A. "You can take a stool softener to prevent constipation." is correct. After a retinal detachment repair, clients should avoid straining during bowel movements, as increased intracranial pressure could affect the healing eye. Taking a stool softener is a helpful preventive measure to avoid constipation.

B. "You can remove your eye patch during the day." is incorrect. The eye patch should typically be worn continuously to protect the eye and support healing. The surgeon's specific instructions should be followed regarding when the patch can be removed.

C. "You should bend from the waist to pick up objects." is incorrect. After retinal surgery, clients should avoid bending from the waist as this can increase intraocular pressure, potentially compromising the surgical repair. Instead, clients should use proper body mechanics and bend at the knees.

D. "You can apply a warm, moist compress to your forehead to reduce pain." is incorrect. Applying a warm compress to the forehead is not typically recommended following a retinal repair. Clients should follow the specific post-operative instructions from the surgeon, which may include cold compresses or other methods of managing discomfort.
