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. "It takes 2 months of scheduled use before this medication is effective." is incorrect. Montelukast is generally effective within 1-2 weeks of starting the medication, not 2 months.

B. "I will give this medication to my child once daily in the evening." is correct. Montelukast is usually administered once daily, in the evening, to help prevent asthma symptoms.

C. "I can stop giving my child this medication if he is taking a steroid." is incorrect. Montelukast and steroids can be used together to manage asthma, but stopping montelukast is not recommended unless advised by the healthcare provider.

D. "I will give this medication to my child every 2 hours if he is wheezing." is incorrect. Montelukast is a maintenance medication and should not be used as a rescue treatment for acute wheezing. For acute symptoms, a short-acting bronchodilator is typically used.

A. Docusate B. Ibuprofen C. Aspirin D. Omeprazole

Correct Answer is A

Explanation

A. Docusate is correct. Docusate is a stool softener, and it does not have a significant effect on blood clotting. Therefore, it is considered safe for use with warfarin, which requires careful monitoring to avoid interactions that may increase bleeding risks.

B. Ibuprofen is incorrect. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID. that can increase the risk of bleeding when used with warfarin by inhibiting platelet aggregation and affecting clotting factors.

C. Aspirin is incorrect. Aspirin also inhibits platelet function, increasing the risk of bleeding when combined with warfarin. This combination should be avoided unless specifically prescribed.

D. Omeprazole is incorrect. Although omeprazole is often used to treat gastrointestinal issues, it may interact with warfarin and affect its metabolism. This interaction can increase the risk of bleeding, and caution is recommended when using these medications together.
