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. Check the client's vital signs every 4 hr.: Although monitoring vital signs is important, it is not the primary concern in acute mania unless the client is showing signs of physical distress (e.g., tachycardia, dehydration).

B. Provide the client with high-calorie finger foods.: This is correct. During acute mania, clients may have difficulty sitting down to eat, and high-calorie finger foods can help ensure the client gets adequate nutrition. These foods are easy to consume and provide the necessary calories.

C. Encourage the client to participate in group activities.: While socialization can be beneficial, group activities may overstimulate a client in acute mania and could lead to further agitation. It is better to encourage more structured and individual activities initially.

D. Allow the client to establish his own schedule.: Clients in acute mania may have poor judgment and impulsive behavior. Allowing them to establish their own schedule could lead to disorganized behavior. The nurse should offer structure to prevent this.

A. There is one finger width between the strap on the mask and the client's face. B. The therapeutic dose of albuterol is being inhaled. C. The mask fits loosely so air can escape from underneath. D. The mask is secured over the client's mouth and the client's nose is uncovered.

Correct Answer is A

Explanation

A. There is one finger width between the strap on the mask and the client's face is correct. A properly fitted CPAP mask should have a snug fit, with a space of about one finger width between the strap and the face to ensure adequate seal and comfort. A mask that is too tight can cause discomfort, while a loose mask may not provide the necessary pressure to treat sleep apnea.

B. The therapeutic dose of albuterol is being inhaled is incorrect. Albuterol is used for bronchodilation in conditions like asthma, but it is not related to CPAP use. CPAP is designed to provide positive pressure to keep the airways open, not to treat asthma or other respiratory issues directly.

C. The mask fits loosely so air can escape from underneath is incorrect. A loose fit would lead to air leakage, reducing the effectiveness of the CPAP therapy. The mask should fit securely to ensure the proper amount of air pressure is delivered during sleep.

D. The mask is secured over the client's mouth and the client's nose is uncovered is incorrect. For effective CPAP therapy, the mask should cover both the nose and mouth, unless the client specifically uses a nasal CPAP mask designed to deliver pressure only through the nose.
