ATI Capstone Pharmacology Assessment Questions
Question 1 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 2 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.
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
Penicillin's effectiveness against rapidly growing cell is primarily due to its effect on what?
Correct Answer: C
Rationale: Penicillin is a type of antibiotic that works by disrupting the synthesis of the bacterial cell wall. Bacterial cells have a cell wall that provides structural support and protection. The cell wall is composed of peptidoglycan, a complex molecule that gives the cell wall its strength. Penicillin interferes with the formation of peptidoglycan by inhibiting the enzyme transpeptidase, which is essential for cross-linking the peptidoglycan strands. As a result, bacterial cells become more susceptible to osmotic pressure and eventually burst, leading to their death. This mechanism of action is particularly effective against rapidly growing bacterial cells because they are actively synthesizing new cell wall components to keep up with their growth. Thus, penicillin's primary effectiveness against rapidly growing cells is primarily due to its disruption of cell wall synthesis.
