A nurse is implementing interventions to prevent a patient from developing Deep Vein Thrombosis (DVT) in the legs by applying a pneumatic or sequential compression device (SCD's). Which explanation would the nurse give the patient in regards to how this device works?

Air pads wrap around your arms and are connected to a vacuum which improves blood flow.

These are elastic stockings that apply pressure to the legs and increase the velocity of blood flow.

SCDs are only worn during amputation to provide support and prevent pooling of blood in the legs.

The device fills with air that applies intermittent or sequential pressure to the legs to enhance blood flow and venous return.

Answer and Explanation

The Correct Answer is D

The correct answer is choice D. The nurse would explain to the patient that SCDs work by filling with air and applying intermittent or sequential pressure to the legs to enhance blood flow and venous return. This can help prevent blood clots, such as DVT, from forming in the legs. SCDs are often used for patients who are immobile, such as those who have undergone surgery or who are hospitalized for a medical condition. The device is comfortable to wear and can be adjusted to fit the patient's size and shape. The nurse would also explain the importance of wearing the device as prescribed, and how to properly use and care for it. By using SCDs as directed, the patient can significantly reduce their risk of developing a potentially life-threatening blood clot.

Correct Answer is C

Explanation

Correct answer: C

C. The nurse turns and their back is facing the sterile field.Turning one’s back to the sterile field is a breach of sterile technique because it increases the risk of contamination. The sterile field must always be in the nurse’s line of sight to ensure it remains uncontaminated.

Incorrect Options:

A. The nurse applies sterile gloves and touches a sterile object in the sterile field.This is correct practice. Sterile gloves are used to handle sterile objects within the sterile field to maintain sterility.

B. The nurse disposes of an opened container of sterile saline after 24 hours.This is correct practice. Sterile saline should be discarded after 24 hours to prevent contamination.

D. The nurse keeps hands above waist level while donning sterile gloves.This is correct practice. Keeping hands above waist level helps maintain sterility by preventing contact with non-sterile surfaces.

Correct Answer is ["1.8"]

Explanation

First, let's convert 90 mcg to mg:

90 mcg = 0.09 mg

Next, we can use dimensional analysis to calculate the required mL: 0.09 mg Lanoxin x 1 mL/0.05 mg Lanoxin = 1.8 mL

Therefore, the nurse will give 1.8 mL of Lanoxin elixir.

Rounding to the nearest tenth, the answer is 1.8 mL.
