A nurse is mentoring a new nurse who is learning to start IVs. The nurse tells the new nurse that in case the patient needs subsequent venipuncture sites, the best place to initially start an IV is the:

most appropriate distal vein on the nondominant arm.

most appropriate proximal vein available on either arm.

antecubital vein of the patient's nondominant arm.

antecubital vein of the patient's dominant arm.

Answer and Explanation

The Correct Answer is A

A. Distal veins, such as those in the hand or forearm of the nondominant arm, are often preferred for initial IV placement. These veins are typically smaller but can be easier to access and cause less discomfort for the patient compared to more proximal veins.

B. Proximal veins, such as those in the upper arm (brachial or basilic veins), may be considered if distal veins are not accessible or suitable. However, proximal veins are larger and can be more difficult to cannulate, potentially causing more discomfort and increasing the risk of complications.

C. The antecubital veins, located in the bend of the elbow, are commonly used for venipuncture due to their accessibility and size. The antecubital vein of the nondominant arm is often preferred to minimize interference with the patient's daily activities and reduce the risk of complications associated with frequent use of the dominant arm.

D. While the antecubital vein of the dominant arm may also be accessible, it is generally recommended to preserve this area for procedures that require a higher level of dexterity and strength. Frequent venipuncture in the dominant arm can lead to discomfort and potential complications, such as phlebitis or thrombosis.

Correct Answer is B

Explanation

B. One of the significant changes that occur with aging is a decline in kidney function. This includes a decrease in renal blood flow, glomerular filtration rate (GFR), and the ability of the kidneys to concentrate urine. These changes can impair the body's ability to conserve water and maintain electrolyte balance, increasing the risk of dehydration.

A. As individuals age, there is actually a decrease in the percentage of body water relative to lean body mass. This is because aging is associated with an increase in adipose tissue and a decrease in muscle mass, which affects the overall body composition.

C Saliva production typically decreases with age, rather than increases. Reduced saliva production can contribute to dry mouth and may affect hydration status indirectly, but it is not a primary factor in increasing dehydration risk in older adults.

D. While changes in blood pressure can occur with aging, such as an increase in systolic blood pressure due to arterial stiffening, this does not directly contribute to an increased risk of dehydration. Blood pressure changes are more related to cardiovascular health rather than fluid balance.

A. Administer the medication using a filter needle. B. Break the ampule by bending the top to the side. C. Flick the bottom of the ampule several times. D. Withdraw medication from the center of the ampule. E. None F. None

Correct Answer is A

Explanation

A. Using a filter needle is indeed a recommended practice when withdrawing medication from an ampule. This is because filter needles are designed to prevent glass particles from being drawn into the syringe after breaking the ampule.

B. Ampules should not be bent to open them. The proper method involves using a gauze or an ampule opener to snap the neck of the ampule away from the body. Bending the ampule can lead to shards of glass, risking injury to the nurse or contamination of the medication.

C. The ampule should be tapped gently to ensure all medication is in the lower portion before opening.

D. Withdrawing medication from the center of the ampule is the correct action because it ensures that the needle does not touch the broken glass edges, which could contaminate the medication or dull the needle.
