ATI Capstone Pharmacology Assessment Questions
Question 1 of 5
What is the pharmacological action of meç€æ˜€ormin?
Correct Answer: A
Rationale: Metformin belongs to the class of medications known as biguanides. Biguanides work primarily by decreasing glucose production in the liver and increasing insulin sensitivity in peripheral tissues, such as muscles. They also help improve glucose uptake and utilization by cells, leading to better control of blood sugar levels. Metformin is commonly used to treat type 2 diabetes mellitus and can also be used in the management of polycystic ovary syndrome (PCOS).
Question 2 of 5
A patient requires a nonopioid medication. The nurse knows that which medication will cause the least gastrointestinal distress?
Correct Answer: C
Rationale: Celecoxib is a selective COX-2 inhibitor, which means it primarily targets the COX-2 enzyme involved in inflammation and pain while sparing the COX-1 enzyme that protects the stomach lining. This selectivity reduces the risk of gastrointestinal distress, such as ulcers and bleeding, compared to non-selective NSAIDs like aspirin, ketorolac, and ibuprofen.
Therefore, celecoxib is the best choice for patients who require a nonopioid medication with minimal gastrointestinal side effects. Nurses should consider this when selecting pain management options for patients with a history of gastrointestinal issues.
Question 3 of 5
A patient with a history of HF presents to the emergency department with difficulty breathing, cough, and edema of the lower extremities. The nurse anticipates administration of which type of medication?
Correct Answer: C
Rationale: In the scenario described, the patient with a history of heart failure (HF) is presenting with symptoms of difficulty breathing, cough, and edema of the lower extremities. These signs and symptoms suggest acute decompensated heart failure (ADHF), which is characterized by a decrease in cardiac output and inadequate tissue perfusion. In this situation, the nurse would anticipate the administration of a positive inotrope medication.
Question 4 of 5
Which nursing diagnosis is appropriate for a patient receiving antidysrhythmics?
Correct Answer: C
Rationale: The appropriate nursing diagnosis for a patient receiving antidysrhythmics would be Deficient fluid volume. Antidysrhythmics can have side effects such as electrolyte imbalances, which can lead to fluid volume deficit. Monitoring the patient's fluid intake and output is crucial to prevent dehydration and maintain proper electrolyte balance.
Therefore, identifying Deficient fluid volume as a nursing diagnosis allows for appropriate interventions to be implemented to address and prevent this potential complication.
Question 5 of 5
The nurse notes in the patient™s medication orders that the patient will be taking ibutilide (Corvert). Based on this finding, the nurse interprets that the patient has which disorder?
Correct Answer: B
Rationale: Ibutilide (Corvert) is a medication commonly used to treat atrial fibrillation, a type of irregular heart rhythm that originates in the heart's upper chambers (atria). It works by restoring normal heart rhythm in patients with atrial fibrillation.
Therefore, the nurse notes the use of ibutilide in the patient's medication orders, indicating that the patient has atrial fibrillation.
