A nurse is teaching a client scheduled for an activated partial thromboplastin time (aPTT). Which of the following statements by the client indicates an understanding of the teaching?
"This test will help my provider adjust my warfarin dosages."
"If my levels are too low, I am at an increased risk for bleeding."
"It measures deficiencies in clotting factors."
"I will need to skip breakfast until after the test is complete
The Correct Answer is C
A. "This test will help my provider adjust my warfarin dosages": aPTT is not typically used to monitor warfarin therapy. Instead, it is more commonly associated with monitoring heparin therapy.
B. "If my levels are too low, I am at an increased risk for bleeding": This statement is inaccurate. Low levels of clotting factors could lead to a prolonged aPTT, which might increase the risk of bleeding.
C. "It measures deficiencies in clotting factors."
Activated partial thromboplastin time (aPTT) is a laboratory test that evaluates the intrinsic pathway of the coagulation cascade. The aPTT measures the time it takes for a clot to form and reflects the activity of various clotting factors, including factors VIII, IX, XI, and XII. An elevated aPTT may indicate a deficiency or dysfunction of one or more clotting factors.
D. "I will need to skip breakfast until after the test is complete": There is no need for the client to skip breakfast before an aPTT test. The test is not affected by food intake.

Correct Answer is C
Explanation
A. Impaired tissue perfusion: While impaired tissue perfusion is a concern in clients with varicose veins, the presence of ulcerations indicates that skin integrity is already compromised. Addressing impaired skin integrity is a more immediate concern.
B. Alteration in activity tolerance: Alteration in activity tolerance may be a consequence of impaired tissue perfusion and impaired skin integrity, but the priority is to address the current skin breakdown and prevent further complications.
C. Impaired skin integrity: This is the correct answer. The presence of varicose veins, ulcerations, and lower extremity edema indicates compromised skin integrity. The nurse should prioritize interventions to promote wound healing, prevent infection, and address the underlying causes contributing to impaired skin integrity.
D. Alteration in body image: While body image concerns may arise in clients with varicose veins, the immediate priority is addressing the physical complications such as impaired skin integrity to prevent further deterioration.
Correct Answer is D
Explanation
A. Restrict the client's fluid intake: There is typically no need to restrict fluid intake after a cardiac catheterization. Adequate hydration is important for preventing complications and promoting recovery.
B. Ambulate the client 1 hr following the procedure: While early ambulation is encouraged in many cases, the timing may vary based on the specific protocols of the healthcare provider. It is important to follow the healthcare provider's orders regarding post-catheterization ambulation.
C. Instruct the client to perform range-of-motion exercises to his lower extremities: Range-of-motion exercises are beneficial to prevent complications such as venous stasis and deep vein thrombosis. However, the specific exercises and timing may vary. It is important to follow the healthcare provider's instructions.
D. Perform neurovascular checks with vital signs: This is the correct answer. After a cardiac catheterization accessed through the femoral artery, it is crucial to monitor neurovascular status in the affected extremity. Assessing peripheral pulses, skin color, temperature, and capillary refill, along with monitoring vital signs, helps detect any signs of complications such as bleeding or vascular compromise.
