ATI Capstone Pharmacology Assessment Questions
Question 1 of 5
A patient in the outpatient oncology clinic complains of fatigue after receiving chemotherapy. Which initial nursing intervention will be most appropriate?
Correct Answer: A
Rationale: Fatigue is a common side effect of chemotherapy and can be caused by various factors, including anemia, poor nutrition, sleep disturbances, or psychological stress. The nurse's first step should be to assess for underlying causes of fatigue, such as trouble sleeping, anemia, or depression. Once the cause is identified, appropriate interventions can be implemented, such as dietary changes, sleep hygiene strategies, or treatment for anemia. Encouraging excessive daytime sleep or strenuous exercise without assessment may worsen fatigue or lead to other complications.
Question 2 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 3 of 5
Reye's syndrome, a potentially fatal illness associated with liver failure and encephalopathy is associated with the administration of which over-the-counter (OTC) medication?
Correct Answer: C
Rationale: Reye's syndrome is linked to the use of aspirin in children and adolescents, particularly during viral infections. It causes severe liver and brain damage. Acetaminophen, ibuprofen, and antihistamines are not associated with this condition. Avoiding aspirin in pediatric patients is critical to prevent this rare but life-threatening syndrome.
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
What is the pharmacological action of metformin?
Correct Answer: A
Rationale: Metformin belongs to the class of medications known as biguanides. Biguanides work by decreasing glucose production in the liver and also improving insulin sensitivity in the muscles, helping to lower blood sugar levels in patients with type 2 diabetes. Additionally, metformin can also reduce glucose absorption in the intestines and increase glucose uptake in peripheral tissues. Its main pharmacological action is to improve glycemic control and reduce hyperglycemia in patients with diabetes.
