A nurse is preparing to insert an IV catheter for a client.
Which of the following actions should the nurse plan to take?

Choose a vein that is palpable and straight.

Select a site on the client's dominant arm.

Apply a tourniquet below the venipuncture site.

Elevate the client's arm prior to insertion.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

Choosing a palpable and straight vein is essential for a successful IV insertion. A vein that is easily palpable and visible helps ensure that the catheter can be inserted smoothly, reducing the risk of complications such as infiltration or extravasation. Additionally, selecting a straight vein makes the insertion process easier and less painful for the client.

Choice B rationale:

Selecting a site on the client's dominant arm is not a requirement for IV insertion. The choice of arm depends on the individual client's condition, vein accessibility, and the healthcare provider's preference. Both arms can be used for IV insertion based on the client's specific needs.

Choice C rationale:

Applying a tourniquet below the venipuncture site helps distend the veins, making them more visible and accessible. This technique can aid in locating suitable veins for insertion. However, it is crucial to release the tourniquet once the vein is accessed to prevent complications such as thrombosis or hematoma.

Choice D rationale:

Elevating the client's arm prior to insertion can cause veins to collapse, making it more challenging to insert the IV catheter. Gravity can assist in distending the veins, so the arm should be positioned at or slightly below the level of the heart during IV insertion to maintain adequate blood flow.

Correct Answer is C

Explanation

The correct answer is Choice C.

Choice A rationale: Eating a meal prior to postural drainage is not recommended.Postural drainage uses gravity to help clear mucus from the lungs, and having a full stomach can cause discomfort and potentially lead to vomiting 1.

Choice B rationale: Pancrelipase is a medication that replaces digestive enzymes produced by the pancreas.Most people with cystic fibrosis benefit from taking pancrelipase to aid their digestion 2. However, it is not specifically required prior to postural drainage.

Choice C rationale: Using an albuterol inhaler prior to postural drainage is beneficial.Albuterol is a bronchodilator that helps open the airways, making it easier to clear mucus from the lungs 3 4. This is why it’s recommended to use prior to postural drainage.

Choice D rationale: While maintaining good oral hygiene is important for overall health, it is not specifically required prior to postural drainage

A. Glargine insulin. B. NPH insulin. C. Insulin aspart. D. Regular insulin.

Correct Answer is A

Explanation

Choice A rationale:

Glargine insulin is a long-acting insulin that provides a basal level of insulin over 24 hours. It is suitable for managing blood glucose levels in clients with diabetes mellitus who require a long-acting insulin to maintain glycemic control throughout the day.

Choice B rationale:

NPH insulin is an intermediate-acting insulin that lasts for about 12-16 hours. While it can be used for blood glucose management, it is not the best choice for a client needing long-acting insulin coverage throughout the day.

Choice C rationale:

Insulin aspart is a rapid-acting insulin used to control postprandial glucose levels. It acts quickly to lower blood sugar after meals and is not suitable for long-acting coverage.

Choice D rationale:

Regular insulin, also known as short-acting insulin, is used to control blood glucose levels during meals. It has a faster onset of action compared to long-acting insulins and is not appropriate for managing basal insulin needs over an entire day.
