ATI Pharmacology Assessment 2 Questions
Question 1 of 5
Which of the following is an action of the drug Metformin?
Correct Answer: A
Rationale: Metformin is a commonly prescribed medication for the treatment of type 2 diabetes. One of the main actions of Metformin is to decrease hepatic glucose production by suppressing gluconeogenesis in the liver. By reducing the amount of glucose produced by the liver, Metformin helps lower blood sugar levels in individuals with diabetes. This action helps improve insulin sensitivity and overall glycemic control in patients with type 2 diabetes. The other options provided in the question do not describe the primary mechanism of action of Metformin.
Question 2 of 5
A 48-year-old man presents to the emergency department in the morning with urticaria and difficulty breathing following a bee sting received while gardening. He is treated, recovers, and is sent home. Later that evening, his symptoms return and he is treated again in the emergency department. He denies having been stung again. What should have been given to this patient to avoid his return to the emergency department?
Correct Answer: D
Rationale: Recurrent allergic symptoms post-bee sting suggest ongoing inflammation. Prednisolone , a corticosteroid, reduces late-phase reactions. Diphenhydramine and Loratadine treat acute symptoms. Epinephrine is for anaphylaxis but short-acting. Prednisolone prevents biphasic reactions, avoiding his return.
Question 3 of 5
The patient with schizophrenia is sitting quietly in a chair. The patient does not respond much to what is happening and has a lack of interest in the environment. How does the nurse interpret this assessment?
Correct Answer: D
Rationale: Schizophrenia's negative symptoms include apathy and withdrawal, seen in quietness and disinterest . Depression needs more evidence. Voices suggest positive symptoms, absent here. Positive symptoms add behaviors, not subtract. D aligns with schizophrenia's clinical presentation, making it the correct interpretation.
Question 4 of 5
When teaching a patient who has a new prescription for transdermal nitroglycerin patches, the nurse tells the patient that these patches are most appropriately used for which situation?
Correct Answer: C
Rationale: Transdermal nitroglycerin patches are most appropriately used to prevent the occurrence of angina. Nitroglycerin is a vasodilator that works by relaxing and widening blood vessels, which helps to increase blood flow and oxygen to the heart muscle. By using nitroglycerin patches regularly, the patient can help prevent episodes of angina, which is chest pain or discomfort that occurs when the heart muscle does not receive enough oxygen-rich blood. Nitroglycerin patches are not used to prevent low blood pressure, relieve shortness of breath, or control heart rate during exercise.
Question 5 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.
