Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?
- A. Spironolactone
- B. Furosemide
- C. Hydrochlorothiazide
- D. Bumetanide
Correct Answer: A
Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics.

An adolescent male is newly diagnosed with schizophrenia. Which of the following antipsychotic agents may have the best chance to improve his apathy and blunted affect?
- A. Chlorpromazine
- B. Fluphenazine
- C. Haloperidol
- D. Risperidone
Correct Answer: D
Rationale: Risperidone, a second-generation antipsychotic, blocks D2 and 5HT2 receptors, improving positive symptoms (hallucinations) and, to some extent, negative symptoms like apathy and blunted affect, common in schizophrenia's prodrome. First-generation agents—chlorpromazine, fluphenazine, haloperidol—target D2 receptors, effectively reducing positive symptoms but often worsening negative symptoms via dopamine blockade in the prefrontal cortex. Thioridazine, also first-generation, has similar limitations. Risperidone's serotonin antagonism may enhance prefrontal dopamine release, offering a modest edge in addressing negative symptoms, supported by studies, making it preferable for this adolescent's presentation.
