A nurse is performing an assessment on a patient who has osteoarthritis of the knee. Which of the following assessment findings should the nurse expect?

Choice A rationale
Hip arthroplasty, or hip replacement surgery, is a procedure that has been associated with a higher risk of deep vein thrombosis (DVT)8910. This is due to factors such as the length of the

procedure, the immobility of the patient during and after the procedure, and the location of the surgery in the lower extremities.
Choice B rationale
Cataract extraction is not typically associated with a high risk of DVT8910. This is a relatively quick and minimally invasive procedure, and it does not involve the lower extremities, which are the most common sites for DVT8910.
Choice C rationale
Myringotomy, a procedure to drain fluid from the middle ear, is not associated with a high risk of DVT8910. This is a quick and minimally invasive procedure, and it does not involve the lower extremities.
Choice D rationale
Laparoscopic appendectomy, while a surgical procedure, is not typically associated with a high risk of DVT8910. The risk of DVT is generally lower with laparoscopic procedures compared to open surgeries.

Choice A rationale
Hepatitis A is a highly contagious virus that spreads through person-to-person contact or consuming contaminated food or drink. The virus can contaminate food during growing, harvesting, processing, handling, and even after cooking. Therefore, avoiding serving raw foods can help prevent the spread of the virus.
Choice B rationale

Hepatitis A is not typically spread through sexual intercourse. It is primarily spread through the fecal-oral route, either by person-to-person contact or consumption of contaminated food or water. Therefore, wearing barrier protection during vaginal intercourse is not a primary prevention strategy for Hepatitis A.
Choice C rationale
While it’s possible to contract Hepatitis A from food prepared at any location, including fast food restaurants, the risk is not specifically associated with these establishments. The key is whether the food is contaminated with the virus, which can occur in any setting if food is handled by someone infected with Hepatitis A who doesn’t properly wash their hands after using the toilet.
Choice D rationale
Practicing effective hand hygiene, including thoroughly washing hands after using the bathroom, changing diapers, and before preparing or eating food, is a primary prevention strategy for Hepatitis A1. The virus is spread in part by the fecal-oral route, so good hand hygiene can help prevent ingestion of the virus.
