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 B
Explanation
A. Aplastic anemia results in an inability to absorb vitamin B12: This statement is incorrect. Aplastic anemia is not related to the absorption of vitamin B12. It primarily involves a decrease in the production of blood cells by the bone marrow.
B. Aplastic anemia results from decreased bone marrow production of RBCs: This is the correct information. Aplastic anemia is a condition characterized by the failure of the bone marrow to produce an adequate number of blood cells, including red blood cells (RBCs), white blood cells (WBCs), and platelets.
C. Aplastic anemia results in an increased rate of RBC destruction: This statement is incorrect. Aplastic anemia is not associated with an increased rate of RBC destruction. Instead, it is characterized by a reduction in the number of blood cells produced by the bone marrow.
D. Aplastic anemia is associated with a decreased intake of iron: This statement is incorrect. Aplastic anemia is not related to a decreased intake of iron. It is primarily a disorder of bone marrow function leading to insufficient production of blood cells.

Correct Answer is D
Explanation
Correct answer: D
A.Elevate the head of the bed 45":Do not elevate the head of the bed more than 15 degrees.Elevating the head of the bed can increase the risk of bleeding from the insertion site.
B.Keep the affected leg slightly flexed: The affected leg should be kept straight to prevent movement at the insertion site, which can cause bleeding
C. Keep the client NPO for 4 hr: There is typically no need to keep the client NPO for an extended period after a cardiac catheterization. However, individual protocols may vary, and the nurse should follow the specific instructions provided by the healthcare provider.
D.Have the client lie flat in bed: After a cardiac catheterization, it is important to keep the client lying flat to prevent bleeding or hematoma formation at the catheter insertion site. This position helps to maintain pressure on the insertion site, particularly if the catheter was inserted through the femoral artery.
