Question 1 of 5
Indication for I.V. IgG preparation administration is:
Correct Answer: D
Rationale: The correct answer is D: Prophylaxis of certain infections. IV IgG preparations are commonly used for prophylaxis against infections in patients with primary immunodeficiencies or those undergoing immunosuppressive therapy. This helps provide temporary immunity to specific pathogens. A: Kaposi's sarcoma - IV IgG preparations are not indicated for the treatment of Kaposi's sarcoma. B: Acute rejection of organ transplant - IV IgG preparations are not used to treat organ rejection. C: Condyloma acuminatum - IV IgG preparations are not indicated for the treatment of condyloma acuminatum. In summary, the correct indication for IV IgG preparation administration is for prophylaxis of certain infections to boost immunity in immunocompromised patients, while the other choices are unrelated to its primary use.
Question 2 of 5
The cholesterol synthesis inhibitors are better tolerated than most other lipid-lowering agents. This consideration is:
Correct Answer: A
Rationale: Step 1: Cholesterol synthesis inhibitors target a specific enzyme, reducing side effects. Step 2: They have a lower incidence of adverse effects compared to other lipid-lowering drugs. Step 3: Therefore, the statement that they are better tolerated is true. Summary: Choice A is correct because of the targeted mechanism and lower side effect profile compared to other lipid-lowering agents. Choices B, C, and D are incorrect as they do not align with the rationale provided.
Question 3 of 5
Indications for 1,25-dihydroxyvitamin D3 (calcitriol) administration are the following, EXCEPT:
Correct Answer: D
Rationale: The correct answer is D: Elevated skeletal turnover. 1,25-dihydroxyvitamin D3 (calcitriol) is administered for hypocalcemia in chronic renal failure, vitamin D-dependent rickets, and malabsorption of vitamin D. Elevated skeletal turnover is not an indication for calcitriol as it can exacerbate bone resorption. Administering calcitriol in such cases can lead to increased calcium release from bones and worsen the condition. Therefore, D is the correct answer.
Question 4 of 5
Which of the following statements about spironolactone is TRUE?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
Which of the following groups of antibiotics demonstrates a bacteristatic effect:
Correct Answer: B
Rationale: The correct answer is B: Macrolides. Macrolides exert a bacteriostatic effect by inhibiting bacterial protein synthesis. They do not directly kill bacteria but rather prevent their growth and reproduction. Carbapenems (A), aminoglycosides (C), and cephalosporins (D) are examples of antibiotics that typically exhibit bactericidal effects, meaning they directly kill bacteria. Therefore, Macrolides are the only group among the options that demonstrate a bacteriostatic effect.
