A nurse is using a glucometer to measure a client's capillary blood glucose level. Which of the following actions should the nurse take?
Select the central tip of a finger.
Wear sterile gloves.
Keep the finger in a dependent position.
Milk or massage the finger site.
The Correct Answer is C
Choice A Reason:
Select the central tip of a finger is incorrect. The nurse should select a puncture site on the side of the finger, slightly off-center from the central tip, as it tends to be less painful. The side of the finger has an adequate blood supply and can provide an accurate blood sample without causing excessive discomfort.
Choice B Reason:
Wearing sterile gloves is incorrect. Sterile gloves are not typically necessary for routine capillary blood glucose monitoring. However, clean hands and proper hand hygiene are essential. The nurse should perform hand hygiene before the procedure.
Choice C Reason:
Keeping the finger in a dependent position is correct. Keeping the finger in a dependent position (hanging down) can promote blood flow and make it easier to obtain a blood sample. This is a recommended technique to facilitate the puncture and collection of blood.
Choice D Reason:
Milking may hemolyze specimen and introduce excess tissue fluid.

Correct Answer is A
Explanation
Alcohol withdrawal can often lead to an increase in blood pressure. The autonomic nervous system becomes hyperactive during withdrawal, resulting in increased sympathetic activity, which can elevate blood pressure.
Constipation is not typically associated with alcohol withdrawal. However, chronic alcohol use can affect the gastrointestinal system and lead to digestive issues, including diarrhea or gastrointestinal bleeding.
Polyuria, which refers to excessive urination, is not a typical manifestation of alcohol withdrawal. However, alcohol use can affect fluid balance and lead to changes in urination patterns.
Bradycardia, or a slow heart rate, is not a common manifestation of alcohol withdrawal. Instead, tachycardia (an increased heart rate) is more commonly observed during withdrawal due to the hyperactivity of the autonomic nervous system.
Correct Answer is D
Explanation
Choice A Reason:
Clear rhinorrhea (runny nose without any other symptoms) is not a contraindication for receiving the varicella vaccine. Contraindications typically involve more serious medical conditions or situations where the vaccine could be harmful.
Choice B Reason:
Medications for a cardiac anomaly. Taking medications for a cardiac anomaly is not a contraindication for the varicella vaccine. In fact, some children with cardiac anomalies may be at higher risk for complications from chickenpox and may benefit from vaccination.
Choice C Reason:
Two diarrhea stools in the last day. Having a couple of episodes of diarrhea in the last day is not a contraindication for the varicella vaccine. Contraindications usually involve more severe or systemic conditions that can affect the safety and effectiveness of the vaccine.
Choice D Reason:
Chemotherapy treatments is correct. A contraindication for receiving a varicella (chickenpox) immunization is undergoing chemotherapy or other immunosuppressive therapies. Children who are immunocompromised should not receive live vaccines like the varicella vaccine because of the risk of developing the disease due to their weakened immune system.
