ATI Pharmacology Exam Practice Questions
Question 1 of 5
Patients should avoid what drink while taking Alprazolam?
Correct Answer: B
Rationale: Patients taking Alprazolam should avoid consuming grapefruit juice. Grapefruit juice can interfere with the metabolism of Alprazolam in the body, leading to increased levels of the medication in the bloodstream. This can potentiate the sedative effects of Alprazolam and increase the risk of side effects or overdose. It is best to consult with a healthcare provider or pharmacist regarding any potential interactions with grapefruit juice and medications.
Question 2 of 5
A solution for the eyes
Correct Answer: D
Rationale: Collyria refers to eye drops or an eye lotion that is used to treat eye conditions. When the question is asking for a solution for the eyes, collyria is the most appropriate choice among the options given. Effervescent, mucilage, and spirits do not specifically relate to eye treatments. Collodion is a type of liquid adhesive used in medical settings, but it is not primarily intended for eye-related issues. Therefore, collyria is the correct solution for the eyes.
Question 3 of 5
Which of the following most accurately describes the antibacterial mechanism of penicillin:
Correct Answer: B
Rationale: Penicillin is a type of antibiotic that works by inhibiting bacterial cell wall synthesis. Peptidoglycan is a critical component of the bacterial cell wall, providing structural support and preventing the cell from bursting. Penicillin specifically targets the final step in peptidoglycan synthesis, known as cross-linking, by binding to and inhibiting the enzyme transpeptidase. Without proper cross-linking of peptidoglycan, the bacterial cell wall becomes weak and compromised, leading to cell lysis and bacterial death. This mechanism makes penicillin highly effective in combating bacterial infections.
Question 4 of 5
A patient diagnosed with cancer is scheduled to receive vincristine. Which nursing assessment will have the highest priority when providing care for this patient?
Correct Answer: D
Rationale: Vincristine is known to cause peripheral neuropathy, a common and potentially debilitating side effect. The nurse should prioritize assessing for signs of neuropathy, such as tingling, numbness, or weakness in the extremities. Alopecia, while distressing, is not as critical as neuropathy, which can affect the patient's mobility and quality of life. Vincristine does not typically cause significant changes in digoxin or phenytoin levels, making these assessments less relevant. Early detection of neuropathy allows for dose adjustments or supportive interventions to minimize long-term damage.
Question 5 of 5
A patient was admitted to the emergency department with a pulse oximeter reading of 85% after a successful prehospital resuscitation from cardiac arrest due to an asthma attack. What is the most important initial drug to administer as ordered?
Correct Answer: D
Rationale: Oxygen is the most important initial intervention for a patient with a low pulse oximeter reading (85%) to correct hypoxia and prevent further complications. While epinephrine (A) and albuterol (C) are used to treat asthma, oxygen is the priority to address the immediate hypoxia. Sodium bicarbonate (B) is not indicated unless there is severe metabolic acidosis.
