ATI Pharmacology Assessment 2 Questions
Question 1 of 5
What is the correct definition for absorption of a drug?
Correct Answer: A
Rationale: The correct definition for absorption of a drug is the movement of a drug from the site of administration (e.g., mouth, skin, injection site) into the bloodstream and then to various tissues of the body. This process is a critical step in the pharmacokinetics of a drug, as it determines the rate and extent to which the drug reaches its target site of action. Absorption can be affected by various factors such as the route of administration, drug formulation, and physiological factors of the individual.
Question 2 of 5
A patient is receiving tetracycline. Which advice should the nurse include when teaching this patient about tetracycline?
Correct Answer: A
Rationale: Tetracycline can cause photosensitivity, increasing the risk of severe sunburn. Patients should be advised to use sunscreen and avoid prolonged sun exposure. Taking antacids with tetracycline is contraindicated, as they can bind to the drug and reduce its absorption. Hearing loss and retinal damage are not associated with tetracycline use. Instead, patients should be monitored for gastrointestinal side effects and advised to take the medication with food if tolerated.
Question 3 of 5
A 29-year-old man with recurrent allergic rhinitis presents to his primary care physician for evaluation. He states that his symptoms are more problematic lately and desires treatment. He has begun on fexofenadine. Which of the following adverse reactions is possible in this patient?
Correct Answer: C
Rationale: Fexofenadine, a non-sedating antihistamine, may cause headache , a common side effect. Anxiety , cough , otitis , and respiratory infection (E) are less frequent. Its minimal CNS penetration suits rhinitis, but headache requires awareness.
Question 4 of 5
What does a patient need to avoid while taking Angiotensin-converting enzymes?
Correct Answer: D
Rationale: Patients taking Angiotensin-converting enzyme (ACE) inhibitors should avoid salt substitutes, foods high in potassium, and foods high in sodium. Salt substitutes often contain potassium chloride, which may cause an increase in potassium levels when combined with ACE inhibitors. Foods high in potassium, such as bananas, oranges, spinach, and potatoes, can also potentially elevate potassium levels when consumed in large amounts. Additionally, foods high in sodium can counteract the effects of ACE inhibitors in managing blood pressure. Therefore, it is important for patients on ACE inhibitors to be mindful of their intake of salt substitutes, high-potassium foods, and high-sodium foods to ensure the effectiveness of their medication and to prevent any potential complications.
Question 5 of 5
A patient with a history of pancreatitis and cirrhosis is also being treated for hypertension. Which drug will most likely be ordered for this patient?
Correct Answer: D
Rationale: Given the patient's medical history of pancreatitis and cirrhosis, both conditions can affect the functioning of the liver and potentially interact with medications that are metabolized by the liver. Captopril is an angiotensin-converting enzyme (ACE) inhibitor, which is often a preferred choice for patients with liver disease as it has minimal hepatic metabolism. This decreased reliance on hepatic metabolism makes captopril a safer choice for this patient compared to other antihypertensive medications that may cause liver-related complications. Additionally, ACE inhibitors like captopril are commonly used in patients with hypertension to help reduce blood pressure and protect against further complications related to cardiovascular health.
