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 C
Explanation
pH 7.22: Indicates acidosis (normal range: 7.35-7.45).
PaCO2 68 mm Hg: Elevated partial pressure of carbon dioxide, suggesting respiratory acidosis (normal range: 35-45 mm Hg).
Base excess -2: Indicates a mild metabolic acidosis.
PaO2 78 mm Hg: Within the normal range (80-100 mm Hg), indicating adequate oxygenation.
Saturation 80%: Below the normal range (95-100%), suggesting some degree of hypoxemia.
Bicarbonate 26 mEq/L: Elevated bicarbonate levels, suggesting metabolic compensation for the respiratory acidosis.
Therefore, the client is experiencing respiratory acidosis with partial metabolic compensation (mild metabolic acidosis).
Correct Answer is B
Explanation
A. Instruct the woman to call 911: This is a correct action, but it should be the second step after the nurse initiates first aid measures. Directing someone to call for emergency assistance is crucial, but immediate intervention to relieve the choking takes precedence.
B. The Heimlich maneuver involves abdominal thrusts and is the recommended technique for relieving choking in a conscious person. It is essential to act quickly and decisively to clear the airway.
C. Ask the partner if he can speak: If the person is unable to speak, cough, or breathe, it may indicate complete airway obstruction. The nurse should not delay intervention by asking if the person can speak but should immediately proceed with measures to relieve the choking.
D. Perform chest compressions: Chest compressions are not indicated for a conscious choking victim. Chest compressions are performed in the context of cardiopulmonary resuscitation (CPR) for an unconscious person with no pulse.
