Question 1 of 5
The nurse is giving intravenous nitroglycerin to a patient who has just been admitted because of an acute myocardial infarction. Which statement is true regarding the administration of the intravenous form of this medication?
Correct Answer: D
Rationale: Intravenous nitroglycerin is commonly administered in infusions along with other medications, such as heparin and morphine, to manage acute myocardial infarction. By giving it in infusions, healthcare providers can control the dosage and titrate it to the patient's response while also minimizing the risk of sudden drops in blood pressure. Additionally, administering nitroglycerin in infusions allows for precise and continuous delivery of the medication to achieve the desired therapeutic effect.
Question 2 of 5
What Medication is used as a Bronchodialtor?
Correct Answer: C
Rationale: Albuterol is a medication commonly used as a bronchodilator. It works by relaxing the muscles in the airways and increasing airflow to the lungs. This medication is commonly used to treat conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory issues where bronchodilation is needed to ease breathing difficulties. Warfarin is an anticoagulant used to prevent blood clots, Lovastatin is a statin medication used to lower cholesterol levels, and Valproate is an anticonvulsant used to treat seizures.

Question 4 of 5
The following drugs must be avoided in severe renal failure (GFR ≤10 mL/min):
Correct Answer: D
Rationale: Metformin is contraindicated in severe renal failure due to the risk of lactic acidosis, a rare but potentially fatal side effect.
Question 5 of 5
Drug X has a median lethal dose of 30 mg and a median effective dose of 10. Drug Y has a therapeutic index of 4, while drug Z has a therapeutic index of 3. Which statement is accurate based on this information?
Correct Answer: C
Rationale: Therapeutic index (TI) = lethal dose (LD50) / effective dose (ED50). Drug X: 30/10 = 3. Drug Y: TI = 4. Drug Z: TI = 3. Higher TI means safer-Drug Y (4) tops X and Z (3), balancing efficacy and toxicity best. X and Y aren't both safer-X matches Z. X's TI isn't 20. Z isn't safest. Y's TI makes it safest.
