ATI VATI Pharmacology Assessment Questions
Question 1 of 5
The nurse administers narcotics to surgical patients. Which statement represents the nurse's best understanding as it relates to the potency of different narcotics?
Correct Answer: B
Rationale: Morphine's higher potency than codeine means less is needed for equal pain relief, a pharmacodynamic fact-e.g., 10 mg morphine matches 60 mg codeine. Allergy isn't potency-related. More adverse effects assume dose equivalence, not potency. Pain relief ties to dose, not potency alone. Potency drives dosing, key for surgical pain control.
Question 2 of 5
What route can ondansetron be given? (select all that apply)
Correct Answer: A
Rationale: Ondansetron, which is commonly used to prevent nausea and vomiting, can be administered via three routes: Orally (PO), Intravenously (IV), and Rectally (Rectal). These routes allow for flexible administration based on the patient's condition and needs. Intramuscular (IM) administration is not a recognized route for ondansetron administration.
Question 3 of 5
When a patient is receiving diuretic therapy, which of these assessment measures would best reflect the patient™s fluid volume status?
Correct Answer: C
Rationale: When a patient is receiving diuretic therapy, the best assessment measures to reflect the patient's fluid volume status are intake, output, and daily weight monitoring.
Question 4 of 5
A patient has taken two doses of interferon Alfa-2b (Intron-A). He comes to the clinic today with the following complaints. Which symptoms would the nurse identify as common adverse effects of this therapy?
Correct Answer: A
Rationale: Interferon Alfa-2b is an immunomodulatory drug used for conditions like hepatitis or cancer, known for causing flu-like symptoms and systemic effects. Common adverse effects include dizziness, fatigue, and anorexia (loss of appetite), as listed in the correct answer (1, 3, 4). Dizziness reflects the drug's impact on the central nervous system, often reported early in therapy. Loss of appetite and fatigue are also hallmark symptoms due to interferon's influence on metabolism and energy levels. An itchy rash , while possible as a hypersensitivity reaction, is less commonly associated with interferon compared to these systemic effects. The nurse must recognize these as expected side effects, distinguishing them from severe reactions requiring intervention. Since the question asks for common adverse effects and the correct answer includes multiple symptoms, choice A (dizziness) is a key identifier among them, supported by its prevalence in clinical use, making it the primary focus here.
Question 5 of 5
The nurse administers IV morphine to a client with acute pain. Which finding requires immediate action?
Correct Answer: A
Rationale: Morphine depresses respiration, and 8 breaths per minute signals overdose, needing immediate action (e.g., naloxone) to reverse hypoventilation. BP of 120/80 and pulse of 90 are normal. Pain at 3/10 shows relief. Respiratory depression is morphine's gravest risk, critical in acute pain where safety trumps comfort, making A the finding requiring swift response.
