A nurse is receiving a telephone prescription for a client who reports having severe nausea. The provider states to administer ondansetron 4 mg every 6 hr as needed for nausea. Which of the following should the nurse clarity when reading back the prescription?

A. Check the client's pedal pulses every hour: Frequent assessment of distal circulation is crucial after a total knee arthroplasty to detect signs of compromised blood flow, such as thromboembolism or compartment syndrome. Monitoring pulses, skin color, and temperature helps identify early complications and prevent tissue damage.

B. Maintain the head of the client's bed in high-Fowler's position: High-Fowler’s position is not recommended post-knee arthroplasty as it can increase strain on the surgical site and reduce venous return from the lower extremities. Keeping the leg elevated and the client in a semi-Fowler’s or supine position is safer.

C. Remove the client's dressing when it becomes saturated: Dressings should only be removed or changed according to the provider’s protocol, typically by sterile technique. Premature removal can increase the risk of infection and disrupt the healing surgical site.

D. Place an abductor wedge under the client's right knee: Abductor wedges are primarily used after hip replacement to maintain hip alignment, not knee arthroplasty. Placing one under the knee could cause discomfort or improper positioning. Proper knee alignment involves elevation and extension support.

A. Garlic: Garlic has been shown to have lipid-lowering properties, helping reduce total cholesterol and low-density lipoprotein (LDL) levels. It is commonly recommended as an adjunct to lifestyle modifications for clients with hypercholesterolemia. Its use should be monitored for interactions with anticoagulants or antiplatelet medications.

B. Valerian root: Valerian root is primarily used for promoting relaxation and improving sleep quality. It does not have evidence supporting cholesterol-lowering effects and would not address elevated lipid levels.

C. Saw palmetto: Saw palmetto is used mainly to manage benign prostatic hyperplasia (BPH) symptoms in men. It does not influence cholesterol metabolism or lipid profiles and is not indicated for hypercholesterolemia.

D. Aloe: Aloe is typically used for skin conditions or as a laxative. While it has some antioxidant properties, it is not effective in lowering cholesterol and is not recommended for managing hyperlipidemia.
