A staff education nurse is evaluating a group of nurses during a new employee orientation on the use of proper body mechanics when lifting. Which of the following images indicates the appropriate use of ergonomic principles?
A.
B.
C.
D.
A
B
C
D
The Correct Answer is A
Using proper body mechanics is vital to prevent injury and ensure safe lifting. Key principles include keeping the back straight and neutral to reduce spinal stress and bending at the knees and hips to engage stronger leg muscles rather than the lower back. Maintaining a shoulder-width stance provides stability, while holding objects close to the body decreases spinal strain. Lifting with the legs, not the back, further protects the spine. Twisting should be avoided—pivoting with the feet maintains alignment and reduces injury risk. Keeping the head and neck aligned with the spine improves posture and visual focus. Using smooth, controlled movements prevents muscle strain and dropped objects. Assessing an object’s weight before lifting helps determine if help or equipment is needed, preventing overexertion. Supportive footwear with a good grip ensures balance and minimizes fall risk. These ergonomic practices promote safety, reduce injuries, and are essential in both clinical and everyday environments.

Correct Answer is B
Explanation
A. Fibrinogen level: This test measures a clotting factor important for hemostasis, but it is not routinely used to monitor warfarin therapy. Fibrinogen levels are more relevant in evaluating bleeding disorders or liver function.
B. INR: The International Normalized Ratio is the standard test used to monitor warfarin effectiveness. It helps determine the appropriate dosing needed to maintain therapeutic anticoagulation and reduce the risk of bleeding or thromboembolism.
C. APTT: Activated partial thromboplastin time is used to monitor heparin therapy, not warfarin. It evaluates the intrinsic pathway of coagulation and is not a reliable indicator of warfarin activity.
D. Platelet count: While important in assessing bleeding risk, platelet count does not provide information on the anticoagulant effect of warfarin. It is not used to guide warfarin dosing decisions.
Correct Answer is A,C,E,B,D
Explanation
A. Assess the appearance of the wound first to determine its condition and document characteristics such as drainage, size, and tissue type before collecting the specimen.
B. Place the swab in the culture tube immediately after obtaining the specimen to prevent contamination and preserve the sample.
C. Cleanse the wound with 0.9% sodium chloride to remove surface contaminants, which helps ensure the culture reflects true pathogens within the wound bed.
D. Cover the wound with a sterile dressing to protect the area from external contamination and promote healing after the specimen has been collected.
E. Obtain the specimen from granulation tissue of the wound, avoiding pooled drainage or necrotic areas, to ensure the most accurate culture results.
