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.
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 C
Explanation
A. "I should perform a self-examination of my testicles weekly" is not recommended. Testicular self-exams should be done monthly, not weekly, as this frequency is enough to notice any changes or abnormalities.
B. "I should bear down when cupping my testes while I'm checking for abnormalities" is incorrect. There is no need to bear down during the self-examination. The testicles should be examined gently and without exerting pressure, as bearing down can make the examination uncomfortable.
C. "I should apply gentle pressure with my thumb and forefinger when examining my testes" is the correct statement. The testicular self-exam should be done gently, with light pressure to feel for any lumps or abnormalities.
D. "I should expect one testicle to be larger than the other" is a common misconception. It is normal for one testicle to be slightly larger than the other, but this should be checked regularly to ensure there are no significant changes or signs of concern.
Correct Answer is B
Explanation
A. "Our child has a better grasp of reality.": This is not the primary goal of methylphenidate. While it may help with focus and attention, the medication's goal is to improve concentration and reduce hyperactive behaviors in children with ADHD, not directly influence their grasp of reality.
B. "Our child is able to complete his homework on time.": This is correct. Methylphenidate, a stimulant used to treat ADHD, helps improve attention, focus, and impulse control. A child who can complete homework on time demonstrates improved attention and task completion, which is the desired outcome.
C. "Our child has lost some weight since his last appointment.": While weight loss can be a side effect of methylphenidate, it is not an indicator that the medication is effective. The goal is to manage ADHD symptoms, not necessarily to cause weight loss.
D. "Our child has increased his daily caloric intake.": This is incorrect. A common side effect of methylphenidate is decreased appetite, so an increase in caloric intake would not be expected.
