Question 1 of 5
Which of the following drugs is used to treat an overactive bladder?
Correct Answer: A
Rationale: The correct answer is A: Oxybutynin. Oxybutynin is an anticholinergic medication that helps relax the bladder muscles, reducing urinary frequency and urgency in overactive bladder. Furosemide (B) is a diuretic used to treat fluid retention, not overactive bladder. Amlodipine (C) is a calcium channel blocker used to treat high blood pressure, not overactive bladder. Metformin (D) is an antidiabetic drug used for managing type 2 diabetes, not overactive bladder. Oxybutynin is the most appropriate choice for treating overactive bladder due to its muscle relaxant effects on the bladder.
Question 2 of 5
A 60-year-old male is prescribed lisinopril for hypertension. Lisinopril works by:
Correct Answer: B
Rationale: The correct answer is B: Inhibiting the conversion of angiotensin I to angiotensin II. Lisinopril is an ACE inhibitor, which blocks the enzyme responsible for converting angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, so by inhibiting its production, lisinopril helps dilate blood vessels, lowering blood pressure. Choice A is incorrect because calcium channel blockers work differently. Choice C is incorrect because aldosterone release is not directly affected by lisinopril. Choice D is incorrect because beta-blockers target a different pathway in the heart.
Question 3 of 5
Which medication is a commonly used antidepressant in the class of selective serotonin reuptake inhibitors (SSRIs)?
Correct Answer: B
Rationale: Step 1: SSRIs are a class of antidepressants that work by increasing serotonin levels in the brain. Step 2: Fluoxetine is an SSRI commonly used to treat depression and other mental health conditions. Step 3: Sertraline, citalopram, and lorazepam are not SSRIs but belong to other classes of medications. Summary: Sertraline, citalopram, and lorazepam are incorrect choices as they do not belong to the SSRI class like fluoxetine does.
Question 4 of 5
Which of the following patients should avoid using albuterol?
Correct Answer: A
Rationale: The correct answer is A: A patient with a history of glaucoma. Albuterol can potentially worsen glaucoma due to its side effect of increasing intraocular pressure. Patients with glaucoma should avoid using albuterol to prevent exacerbating their condition. Patients with asthma (B) benefit from albuterol as it is a bronchodilator. Cough (C) can be a symptom of conditions that albuterol may help treat. Albuterol is generally safe for pregnant patients (D) when the benefits outweigh the risks.
Question 5 of 5
A 60-year-old male is prescribed levothyroxine for hypothyroidism. Levothyroxine works by:
Correct Answer: B
Rationale: The correct answer is B: Replacing deficient thyroid hormone. Levothyroxine is a synthetic form of thyroid hormone used to treat hypothyroidism by supplementing the low levels of thyroid hormone in the body. It does not increase TSH production (Choice A), inhibit thyroid hormone synthesis (Choice C), or increase the metabolism of thyroid hormones (Choice D). By providing the missing thyroid hormone, levothyroxine helps restore normal thyroid function and alleviate symptoms of hypothyroidism.
