A client is receiving gentamicin every 12 hours IVPB for an infection. The nurse has administered the 0800 dose, which is prescribed to run over 1 hour. The physician prescribed peak and trough levels to be drawn. The nurse recognizes that the peak level will be drawn at

A. Heparin does not actually "thin" the blood in the sense of reducing viscosity. Instead, it works by inhibiting certain factors in the coagulation cascade, preventing clot formation. Thus, this response does not accurately describe how heparin functions.

B. Heparin works by activating antithrombin III, which inhibits thrombin and factor Xa, thereby preventing the formation of new clots. It does not dissolve existing clots but helps to prevent the enlargement of existing ones and the formation of new clots.
C. Heparin does not decrease the number of platelets; rather, it interferes with the clotting process by inhibiting specific clotting factors. Platelets may still be present, but their ability to form clots is inhibited by the action of heparin.
D. Heparin does not dissolve existing clots; that function is typically performed by thrombolytic agents. Heparin primarily prevents new clot formation and the extension of existing clots. Additionally, it does not decrease platelet formation.

A. Clients with PAD often experience claudication (pain in the legs due to inadequate blood flow) during exercise. They should be encouraged to walk to the point of pain, then rest until the pain subsides, and then continue walking. This approach can improve circulation over time.
B. While it’s crucial to monitor leg ulcers, exercise can still be beneficial unless advised otherwise by a healthcare provider. Walking can promote circulation, which is important for healing. However, if a leg ulcer is present, the client should consult their healthcare provider about appropriate activity levels.
C. While elevating the feet can help reduce swelling, it's generally more beneficial for clients with PAD to keep their legs in a dependent position after walking. This position encourages blood flow to the legs, which can help alleviate symptoms and improve circulation.
D. Exercise that encourages movement and maintains blood flow to the legs is important for those with PAD. While certain positions may exacerbate symptoms, exercises like walking should be encouraged. Keeping the feet in a dependent position can help with blood flow post-exercise.
