Question 2
Losartan belongs to a drug class commonly abbreviated as ARB. What does ARB stand for?
- AAdrenergic receptor blocker
- BAldosterone receptor blocker
- CAngiotensin II receptor blocker
- DAntihistamine receptor blocker
Show answer and explanation
Answer: C) Angiotensin II receptor blocker
ARB stands for angiotensin II receptor blocker (also called an angiotensin II receptor antagonist). Losartan is one example.
- AIncorrect. Drugs that block adrenergic receptors are usually called alpha blockers or beta blockers, not ARBs. Losartan does not work on adrenergic receptors.
- BIncorrect. Aldosterone blockers are a different group of drugs. Losartan works at the angiotensin II receptor, and ARB is not the standard abbreviation for aldosterone blockers.
- CCorrect. ARBs such as losartan (Cozaar) block angiotensin II, a substance that tightens blood vessels. This relaxes the vessels and lowers blood pressure.
- DIncorrect. Antihistamines such as cetirizine block histamine to relieve allergy symptoms. They are not called ARBs, and losartan is not an antihistamine.

Question 6
A patient with hypothyroidism has a prescription for levothyroxine. Which brand-name product contains this drug?
- ACytomel
- BTapazole
- CSynthroid
- DToprol XL
Show answer and explanation
Answer: C) Synthroid
Levothyroxine is sold under brand names such as Synthroid. It replaces the thyroid hormone the body normally makes in patients with hypothyroidism.
- AIncorrect. Cytomel is a brand of liothyronine, a different thyroid hormone (T3).
- BIncorrect. Tapazole is a brand of methimazole, which treats an overactive thyroid (hyperthyroidism).
- CCorrect. Synthroid is a brand of levothyroxine, which replaces thyroid hormone in hypothyroidism.
- DIncorrect. Toprol XL is a brand of extended-release metoprolol, a beta blocker.
Question 7
Drugs whose names end in '-dronate,' such as alendronate, are used mainly to treat which condition, and how do they work?
- AOsteoporosis, by slowing the breakdown of bone
- BHypertension, by blocking angiotensin conversion
- CType 2 diabetes, by lowering liver glucose output
- DHigh cholesterol, by blocking cholesterol synthesis
Show answer and explanation
Answer: A) Osteoporosis, by slowing the breakdown of bone
The '-dronate' suffix marks bisphosphonates such as alendronate. They prevent bone breakdown and increase bone density, which is why they are used for osteoporosis.
- ACorrect. Alendronate is a bisphosphonate. It prevents bone breakdown and increases bone density, so it is used to treat and prevent osteoporosis (and Paget's disease of bone). Patients take it on an empty stomach with a full glass of plain water and stay upright for at least 30 minutes.
- BIncorrect. Blocking angiotensin conversion describes ACE inhibitors, whose names end in '-pril' (e.g., lisinopril). '-dronate' drugs act on bone.
- CIncorrect. Lowering the liver's glucose output describes metformin. Bisphosphonates do not treat diabetes.
- DIncorrect. Blocking cholesterol synthesis describes statins, whose names end in '-statin'. '-dronate' drugs treat bone loss.
Question 8
A very common side effect of opioid pain medicines is:
- ADiarrhea
- BConstipation
- CWeight gain from fluid
- DIncreased alertness

Question 10
A patient mentions she recently started taking St. John's wort, an herbal supplement. Which of her prescription medications is most likely to become less effective as a result?
- AMetformin
- BLisinopril
- COral contraceptives
- DAmoxicillin
Show answer and explanation
Answer: C) Oral contraceptives
St. John's wort induces drug-metabolizing enzymes and can reduce the effectiveness of hormonal contraceptives. Patients should tell their prescriber and may need a backup birth control method.
- AIncorrect. Metformin is not processed by the liver enzymes that St. John's wort speeds up, so it is not a classic St. John's wort interaction.
- BIncorrect. Lisinopril leaves the body largely unchanged through the kidneys. It is not a known example of a drug that St. John's wort makes less effective.
- CCorrect. MedlinePlus lists St. John's wort as an herbal product that interacts with oral contraceptives. It speeds up how fast the hormones are broken down, which can lower contraceptive effectiveness and cause breakthrough bleeding or unintended pregnancy.
- DIncorrect. Amoxicillin is mostly cleared by the kidneys and is not a classic St. John's wort interaction.
