A nurse is teaching a client who has a new diagnosis of aplastic anemia. Which of the following information should the nurse include in the teaching?
Aplastic anemia results in an inability to absorb vitamin B12.
Aplastic anemia results from decreased bone marrow production of RBCs.
Aplastic anemia results in an increased rate of RBC destruction.
Aplastic anemia is associated with a decreased intake of iron.
The Correct Answer is B
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
A. Troponin is a lipid whose levels reflect the risk for coronary artery disease: This statement is incorrect. Troponin is not a lipid, and its levels do not reflect the risk for coronary artery disease. Troponin is a protein associated with muscle tissue.
B. Troponin is an enzyme that indicates damage to brain, heart, and skeletal muscle tissues: While troponin indicates damage to muscle tissues, it is specifically associated with cardiac muscle, not brain or skeletal muscle tissues.
C. Troponin is a protein that helps transport oxygen throughout the body: This statement is incorrect. While proteins in the blood may contribute to oxygen transport, troponin's primary role is in muscle contraction, particularly in the heart.
D. Troponin is a heart muscle protein that appears in the bloodstream when there is damage to the heart: This is the correct answer. Troponin is a protein found in cardiac muscle cells, and when there is damage to the heart, such as during a myocardial infarction, troponin is released into the bloodstream. Elevated troponin levels in the blood are indicative of myocardial injury or infarction.
Correct Answer is A
Explanation
A. Carvedilol:Carvedilol is a non-selective beta-blocker that blocks both beta-1 and beta-2 adrenergic receptors. Beta-2 blockade can lead to bronchoconstriction, which can exacerbate asthma symptoms. Clarification is needed to see if a cardioselective beta-blocker (like metoprolol) would be safer.
B. Captopril:Captopril is an ACE inhibitor commonly used in heart failure to reduce blood pressure and decrease the workload on the heart. It does not have bronchoconstrictive effects and is safe for use in clients with asthma.
C. Isosorbide dinitrate:Isosorbide dinitrate is a nitrate used to manage heart failure by dilating blood vessels and reducing the workload of the heart. It has no effect on bronchial smooth muscle and is not contraindicated in asthma, so no clarification is needed.
D. Fluticasone:Fluticasone is an inhaled corticosteroid used to manage asthma by reducing inflammation in the airways. It is beneficial in clients with asthma and does not pose a risk to clients with heart failure. There is no need to clarify this medication.
