Correct Answer: A

Rationale: Aplastic anemia is a condition characterized by a reduction in the number of all three blood cell types: red blood cells, white blood cells, and platelets. The patient's presentation of bone pain, fatigue, frequent infections, pancytopenia (decreased counts of all blood cell types), hypocellular bone marrow (reduced cellularity in the bone marrow), and absence of reticulocytes is indicative of aplastic anemia.

Correct Answer: C

Rationale: In qualitative research, a focus group discussion is a technique where a group of participants are brought together to discuss specific topics in depth. In this case, Nurse Carmi's plan to gather 6 participants who are victims of domestic violence aligns well with the focus group discussion technique. By involving multiple participants who have experienced domestic violence, she can facilitate a dynamic conversation to gather rich data and insights. This approach allows for the exploration of diverse perspectives, experiences, and opinions within the group setting, providing a deeper understanding of the issue at hand. Additionally, focus group discussions can be more cost-effective and efficient than conducting individual interviews when working with a small group of participants. Therefore, conducting a focus group discussion would be an appropriate qualitative research technique for Nurse Carmi's plan to gather data from victims of domestic violence for her questionnaires.

Correct Answer: A

Rationale: The clinical presentation of fatigue, pallor, exertional dyspnea along with the laboratory findings of severe anemia, low serum iron, low transferrin saturation, and elevated TIBC are consistent with iron deficiency anemia. In iron deficiency anemia, there is inadequate iron available for erythropoiesis leading to microcytic hypochromic anemia. The low serum iron and transferrin saturation, along with the elevated TIBC, indicate decreased iron stores and increased iron-binding capacity as the body tries to compensate for the deficiency by increasing absorption and recycling of iron. Anemia of chronic disease typically presents with mild to moderate anemia, normal to low TIBC, and low transferrin saturation due to iron sequestration in macrophages. Sideroblastic anemia usually has elevated serum iron, high saturation, and normal to low TIBC. Thalassemia presents with microcytic hyp

Correct Answer: B

Rationale: The nurse's priority action when noticing an abnormal heart rhythm on the patient's cardiac monitor during surgery is to assess the patient's vital signs and symptoms. This is important because the nurse needs to gather more information about the patient's condition to determine the significance of the abnormal rhythm and the potential impact on the patient's health. By assessing the vital signs and symptoms, the nurse can obtain a more complete picture of the situation and make informed decisions about the next steps in caring for the patient. Once the assessment is done, appropriate actions such as administering medication or notifying the anesthesiologist can be taken based on the findings.

Correct Answer: D

Rationale: Fidelity is a principle in nursing ethics that pertains to being faithful or loyal to commitments and promises made to patients. When Nurse Pat promised to come back to assist in the patient's ambulation after carrying out the physician's order, she is demonstrating fidelity by fulfilling her commitment to the patient's care. This principle helps build trust between the nurse and the patient, ensuring continuity and quality of care.
