Question 1 of 5
Which of the following is a potassium-sparing diuretic?
Correct Answer: B
Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion, making it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis.
Question 2 of 5
A patient states he experiences anxiety and has panic attacks at least once a week. What might be helpful for this patient?
Correct Answer: C
Rationale: Alprazolam (Xanax) is a medication commonly prescribed to treat anxiety disorders and panic attacks. It belongs to the class of medications known as benzodiazepines, which work by enhancing the effects of gamma-aminobutyric acid (GABA) in the brain to produce a calming effect. Phenytoin is an antiepileptic drug, not typically used for anxiety or panic attacks. Lithium is primarily used to treat bipolar disorder, not anxiety. Spironolactone is a diuretic primarily used to treat conditions like high blood pressure and heart failure, not anxiety or panic attacks.
