ATI Perfusion Quizlet

Correct Answer: D

Rationale: A low white blood cell (WBC) count in an older patient is concerning as it indicates a potential compromise in the patient's immune function. White blood cells are crucial for fighting infections and a low count could lead to an increased risk of infections. Hematocrit, hemoglobin, and platelet count are important parameters to assess, but a low WBC count takes priority in this case due to its direct impact on immune health.

Correct Answer: B

Rationale: The correct answer is B: Potential complication: infection. Patients with idiopathic aplastic anemia have pancytopenia, which puts them at a high risk for infections due to decreased production of all blood cells (red blood cells, white blood cells, and platelets). Infection is a significant concern in these patients. Choices A, C, and D are incorrect because seizures, neurogenic shock, and pulmonary edema are not typically associated with idiopathic aplastic anemia. While seizures can occur in some conditions that affect the brain, neurogenic shock is related to spinal cord injury, and pulmonary edema is more commonly seen in conditions like heart failure.

Correct Answer: B

Rationale: The correct answer is B. In chronic anemia, the hematocrit (Hct) value is a crucial indicator of the proportion of red blood cells in the blood. A hematocrit value of 38% indicates a lower than normal level of red blood cells, which aligns with the patient's symptoms of fatigue and palpitations. Choices A, C, and D are incorrect because a low RBC count, normal RBC indices, and a hemoglobin level of 8.6 g/dL do not specifically address the decreased red blood cell mass associated with chronic anemia.

Correct Answer: C

Rationale: The correct answer is C because administering subcutaneous medications falls within the education and scope of practice of an LPN/LVN. Assessing the patient for signs and symptoms of infection, teaching the patient, and developing a discharge plan are tasks that require an RN level of education and scope of practice. LPN/LVNs can assist in patient care, but tasks that involve assessment, teaching, and care planning are typically the responsibility of an RN.

Correct Answer: B

Rationale: In severe hemolytic anemia, the priority nursing intervention is to alternate periods of rest and activity. This approach helps to balance activity levels to prevent excessive fatigue while promoting mobility and preventing complications such as muscle weakness or deconditioning. Providing a diet high in vitamin K (choice A) is not directly related to managing hemolytic anemia. Teaching the patient how to avoid injury (choice C) is important but may not be the immediate priority. Placing the patient on protective isolation (choice D) is not indicated for hemolytic anemia, as it is not a contagious condition.
