How to Study for ATI Pharmacology Proctored Exam Questions
Question 1 of 5
An international traveler diagnosed with malaria is admitted to the emergency department and is prescribed mefloquine hydrochloride. The nurse anticipates that which laboratory test will be ordered?
Correct Answer: A
Rationale: Mefloquine is an antimalarial drug that can cause hepatotoxicity, so liver enzyme tests are often ordered to monitor for liver damage. Blood glucose, sputum culture, and white blood cell count are not directly related to mefloquine use.
Question 2 of 5
A patient is in the intensive care unit and receiving an infusion of milrinone (Primacor) for severe
Correct Answer: D
Rationale: Milrinone is a phosphodiesterase inhibitor used to improve cardiac contractility and reduce pulmonary congestion in patients with heart failure. Furosemide is a loop diuretic used to reduce fluid volume in patients with congestive heart failure. Given that both milrinone and furosemide are typically administered intravenously and may have potentially incompatible effects on fluid and electrolyte balance, it is critically important to administer them separately. Mixing these medications in the same intravenous line can lead to potential drug interactions or decrease the effectiveness of either drug.
Question 3 of 5
Which drug goes through extensive first-pass hepatic metabolism?
Correct Answer: C
Rationale: Propranolol goes through extensive first-pass hepatic metabolism. This means that after oral administration, a significant portion of the drug is metabolized by the liver before it reaches systemic circulation. This process reduces the bioavailability of propranolol. As a result, higher doses are often required for oral administration compared to other routes of administration, such as intravenous. Heparin, insulin, nitroglycerine, and warfarin do not undergo extensive first-pass metabolism in the liver.
Question 4 of 5
What is the therapeutic classification of Omeprazole?
Correct Answer: B
Rationale: Omeprazole belongs to the therapeutic class of antiulcer agents. It is a proton pump inhibitor that works by decreasing the amount of acid produced in the stomach. Omeprazole is commonly used to treat conditions such as gastroesophageal reflux disease (GER
D), gastric ulcers, and duodenal ulcers. It helps reduce symptoms such as heartburn, acid reflux, and stomach pain by promoting healing of the stomach lining.
Question 5 of 5
Which patient is the best candidate to receive nesiritide therapy?
Correct Answer: D
Rationale: Nesiritide is a recombinant form of human B-type natriuretic peptide (BNP) that is used for the treatment of acutely decompensated heart failure (HF). It is specifically indicated for patients with acute decompensated HF who have dyspnea at rest. Nesiritide works by promoting vasodilation and natriuresis, which helps alleviate symptoms of acute decompensated HF such as dyspnea and edema.
Therefore, the patient with acutely decompensated HF who has dyspnea at rest is the best candidate to receive nesiritide therapy to help improve their symptoms and hemodynamic status.
