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 A
Explanation
A. Cheyne-Stokes respirations: Cheyne-Stokes respirations are characterized by alternating periods of hyperventilation followed by apnea. This respiratory pattern is often observed in clients with conditions affecting the central nervous system, such as brain injury or stroke.
B. Apneustic respirations: Apneustic respirations are characterized by prolonged, gasping inhalations followed by extremely short, ineffective exhalations. This pattern is associated with damage to the pons, a part of the brainstem.
C. Stridor: Stridor is a high-pitched, noisy breathing sound caused by turbulent airflow through a partially obstructed airway. It is not related to the described alternating pattern of hyperventilation and apnea.
D. Kussmaul respirations: Kussmaul respirations are deep, rapid respirations often seen in metabolic acidosis. They are not characterized by the alternating pattern described in the scenario.
Correct Answer is D
Explanation
A. Dependent edema: Dependent edema is more commonly associated with right-sided heart failure. In left-sided heart failure, fluid accumulates in the lungs, leading to pulmonary symptoms such as cough and frothy sputum.
B. Jugular distention: Jugular distention is often associated with right-sided heart failure due to impaired blood flow from the right atrium into the right ventricle. It is less likely to be prominent in left-sided heart failure.
C. Nocturnal polyuria: Nocturnal polyuria (increased urination at night) is a common symptom of heart failure, but it is not specific to left-sided heart failure. It can be seen in both left- and right-sided heart failure.
D. Frothy sputum: This is the correct answer. Left-sided heart failure can lead to pulmonary congestion, resulting in the accumulation of fluid in the lungs. Frothy, pink-tinged sputum is a characteristic finding in left-sided heart failure and is often associated with pulmonary edema.
