Which drug undergoes extensive first-pass hepatic metabolism?
- A. Heparin
- B. Insulin
- C. Propranolol
- D. Nitroglycerin
Correct Answer: C
Rationale: Propranolol undergoes extensive first-pass metabolism in the liver. When administered orally, propranolol is extensively metabolized by the liver before reaching systemic circulation, leading to reduced bioavailability. This process is known as first-pass hepatic metabolism, which significantly affects the drug's effectiveness and necessitates higher oral doses compared to other routes of administration.

Which of the following is the antidote for Heparin?
- A. Protamine sulfate
- B. Vitamin K
- C. Naloxone
- D. Toradol
Correct Answer: A
Rationale: Protamine sulfate is the antidote for Heparin. Heparin is an anticoagulant used to prevent blood clotting. Protamine sulfate works by binding to heparin, neutralizing its anticoagulant effects. Vitamin K is not the antidote for Heparin; it is used to reverse the effects of warfarin, another type of anticoagulant. Naloxone is an opioid antagonist used to reverse the effects of opioids, and Toradol is a nonsteroidal anti-inflammatory drug (NSAID) used for pain relief.

The toddler refuses to take his oral medication. What is the best suggestion to the mother from the nurse for ensuring the toddler receives his medication?
- A. Tell him you will buy him a toy if he takes the medication
- B. Crush the tablet and mix it with a small amount of jam
- C. Crush the tablet and mix it with milk
- D. Tell him he will be punished if he does not take the medicine
Correct Answer: B
Rationale: Toddlers (1-3) resist meds-crushing a tablet (if safe) and mixing with jam masks taste, easing intake, per developmental needs. Bribery with toys may not work long-term. Milk risks interactions (e.g., tetracycline) or dilution. Punishment distresses, not helps. Jam leverages taste preference, ensuring delivery.
