A nurse is collecting a sputum specimen from a client who has tuberculosis.
Which of the following actions should the nurse take?

Choice A rationale:

Keeping an abduction pillow between the client's legs is a preventive measure to avoid dislocation of the hip prosthesis. This positioning helps maintain the correct alignment of the hip joint, reducing the risk of dislocation. Abduction pillows are commonly used postoperatively after total hip arthroplasty to support proper hip positioning while the patient is in bed.

Choice B rationale:

Elevating the client's affected leg on a pillow when in bed is not recommended after total hip arthroplasty. This position could lead to hip adduction, increasing the risk of prosthesis dislocation. Maintaining abduction (spreading the legs apart) is the key to preventing dislocation, and elevation should be avoided to maintain proper alignment.

Choice C rationale:

Positioning the client's knees slightly higher than the hips when up in a chair is not an appropriate preventive measure for prosthesis dislocation. Proper alignment is crucial, and the client should avoid sitting in low chairs or on low surfaces that could cause the hips to be lower than the knees, potentially leading to dislocation.

Choice D rationale:

Raising the head of the client's bed to a high-Fowler's position is unrelated to preventing prosthesis dislocation. Fowler's position refers to elevating the head of the bed to assist with breathing and facilitate patient comfort. While this position might be suitable for certain respiratory conditions, it has no direct impact on the stability of a hip prosthesis.

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.
