Question 1 of 5
Which of the following is a cause of secondary neutropaenia in adults?
Correct Answer: C
Rationale: Rationale: Secondary neutropenia in adults is often a part of general pancytopenia, which involves a decrease in all three blood cell types. This can be caused by factors such as bone marrow suppression from chemotherapy, radiation therapy, or certain medications. Neutropenia is not typically congenital or familial in adults, and anti-hypertensive drugs are not commonly known to directly cause secondary neutropenia. Therefore, the correct answer is C as it aligns with the common etiology of secondary neutropenia in adults.
Question 2 of 5
The nurse is explaining the role of red blood cells with oxygen transport in the body with a nursing student. Which term should the nurse use to describe hemoglobin that has given up its oxygen to the body's cells?
Correct Answer: A
Rationale: The correct term to describe hemoglobin that has given up its oxygen to the body's cells is "Reduced" (Choice A). This term refers to hemoglobin that has released its oxygen molecules and is now in a deoxygenated state. Rationale: 1. Hemoglobin binds to oxygen in the lungs (forming oxyhemoglobin). 2. When hemoglobin reaches the body's cells, it releases oxygen for cellular use. 3. Once hemoglobin releases oxygen, it becomes deoxygenated or "Reduced". Summary: - Choice B (Detached) does not accurately describe the process of oxygen release by hemoglobin. - Choice C (Oxyhemoglobin) refers to hemoglobin bound to oxygen, not hemoglobin that has released oxygen. - Choice D (Hypoxyhemoglobin) would refer to hemoglobin that has a reduced oxygen level, not hemoglobin that has given up its oxygen to the cells.
Question 3 of 5
The nurse is assessing a patient with chronic lung disease. Which finding indicates long-term hypoxia?
Correct Answer: C
Rationale: The correct answer is C: Clubbed fingertips. Clubbing is a sign of prolonged hypoxia due to chronic lung disease. It is characterized by enlargement and rounding of the fingertips. This occurs as a result of chronic hypoxia causing tissue changes in the fingers. Pallor (A) is a pale skin color often indicating decreased blood flow. Dyspnea (B) is difficulty breathing and can be an acute symptom of hypoxia. Pulmonary crackles (D) are abnormal lung sounds indicating fluid accumulation and are not specific to long-term hypoxia.
Question 4 of 5
A patient receiving blood begins complaining of severe chest pain and a feeling of warmth. What should the nurse do first?
Correct Answer: C
Rationale: The correct first action is to discontinue the blood transfusion (Choice C). This is because the patient's symptoms of severe chest pain and warmth suggest a possible transfusion reaction, which can be life-threatening. By stopping the transfusion, the nurse can prevent further harm to the patient. Calling the physician (Choice A) can be done after stopping the transfusion. Administering diuretics (Choice B) without knowing the cause of symptoms can exacerbate the situation. Assessing vital signs and cardiovascular status (Choice D) is important but should come after stopping the transfusion to prioritize patient safety.
Question 5 of 5
An older adult patient is receiving a transfusion of packed red blood cells after being injured in a car accident. On assessment, the nurse notes a new finding of bounding pulse, crackles, and increasing dyspnea. What should the nurse do first, after stopping the transfusion?
Correct Answer: B
Rationale: The correct answer is B: Raise the head of the bed. This action is crucial in managing the potential complication of fluid overload in the patient receiving a blood transfusion. Elevating the head of the bed helps reduce venous return to the heart, decreasing preload and cardiac workload. This can alleviate symptoms like dyspnea and crackles associated with fluid overload. Assessing vital signs (choice A) is important but should follow positioning the patient appropriately. Encouraging deep breathing and coughing (choice C) may exacerbate the patient's respiratory distress. Administering diphenhydramine (choice D) is not indicated for the symptoms described.
