ATI Pathophysiology Final Exam

1. Which of the following mediates humoral immunity?

Correct answer: C

Rationale: Humoral immunity is mediated by B cells, not natural killer cells, T cells, or neutrophils. B cells are responsible for producing antibodies, which are essential components of humoral immunity.

2. In a patient with chronic kidney disease and a hemoglobin level of 9 g/dL, which of the following treatments is most appropriate?

Correct answer: B

Rationale: In chronic kidney disease, anemia commonly occurs due to decreased erythropoietin production. Erythropoiesis-stimulating agents, such as erythropoietin or darbepoetin, are the mainstay of treatment to stimulate red blood cell production. Iron supplementation is more appropriate for iron-deficiency anemia, not the anemia of chronic kidney disease. Blood transfusion is reserved for severe cases or acute blood loss. Vitamin B12 supplementation is indicated for megaloblastic anemia caused by vitamin B12 deficiency, not specifically in chronic kidney disease-related anemia.

3. In which of the following patients may the administration of a live vaccine be contraindicated?

Correct answer: C

Rationale: The correct answer is C. The administration of live vaccines may be contraindicated in patients taking steroid therapy. Steroids can suppress the immune system, reducing the effectiveness of live vaccines. Patients with renal insufficiency or hepatic failure can typically receive live vaccines as these conditions are not direct contraindications. Age alone, such as being over 65 years old, is not a contraindication for live vaccines unless there are other specific health considerations. Therefore, the patient taking steroid therapy is the most likely candidate for whom the administration of a live vaccine would be contraindicated.

4. Not realizing that its surface was hot, a woman has quickly withdrawn her hand from the surface of a bowl that she was removing from a microwave. Which phenomena has facilitated the rapid movement of her hand in response to the painful stimulus?

Correct answer: C

Rationale: The withdrawal reflex is a protective response that allows a person to quickly remove their hand from a painful stimulus.

5. Interpret the following arterial blood gas results: PH = 7.30; PaCO2 = 55 mmHg; HCO3 = 24 mEq/L

Correct answer: A

Rationale: The correct answer is A: Respiratory acidosis. In respiratory acidosis, there is an accumulation of CO2 in the blood, leading to a decrease in pH. The elevated PaCO2 of 55 mmHg in the given results indicates hypoventilation, causing respiratory acidosis. Choices B, C, and D are incorrect because the provided data does not show metabolic acidosis, respiratory alkalosis, or metabolic alkalosis.
