ATI Capstone Pharmacology Assessment 1 and 2 Questions
Question 1 of 5
A patient states during a medical history that he takes several acetaminophen tablets throughout the day for acute pain. The nurse teaches the patient that the dosage should not exceed which amount?
Correct Answer: C
Rationale: Acetaminophen is a commonly used analgesic and antipyretic, but excessive doses can lead to severe liver damage. The maximum recommended daily dose for adults is 4 grams (4000 mg). Exceeding this limit increases the risk of hepatotoxicity, which can be life-threatening. Nurses should educate patients about the importance of adhering to the recommended dosage and checking the acetaminophen content in over-the-counter medications to avoid accidental overdose. This teaching is critical for patient safety and preventing adverse outcomes.
Question 2 of 5
A patient is receiving an IV infusion of a thrombolytic drug during treatment for an acute MI. The nurse notices that there is a slight amount of bleeding from the antecubital area where venous lab work was drawn. What will the nurse do first?
Correct Answer: B
Rationale: In this situation, the nurse's first priority should be to apply pressure to the site with a gauze pad. Bleeding from the antecubital area where venous lab work was drawn can be due to the effect of the thrombolytic drug, particularly in a patient who is already at risk for bleeding due to the acute MI. Applying pressure to the site will help control the bleeding and prevent any further complications. Once the bleeding is controlled, the nurse should monitor the site closely for any signs of increased bleeding or other complications. Slowing the rate of infusion or stopping the infusion of the thrombolytic drug may be considered depending on the severity of the bleeding and the patient's overall condition, but the immediate response should be to apply pressure to the site.
Question 3 of 5
The nurse is aware that the patients who are allergic to intravenous contrast media are usually also allergic to which of the following products?
Correct Answer: B
Rationale: Shellfish allergy is a common indicator of potential hypersensitivity to iodinated contrast media due to the shared allergen, iodine. Patients with shellfish allergies should be screened carefully before receiving contrast media. Allergies to eggs, soy, and acidic fruits are not directly related to contrast media reactions.
Question 4 of 5
What is important to monitor when giving the drug Phenytoin?
Correct Answer: D
Rationale: When giving the drug Phenytoin, monitoring urinary pH is important because Phenytoin is known to be excreted by the kidneys. Changes in urinary pH can affect the concentration of Phenytoin in the body. Alkaline urine can increase the excretion of Phenytoin, potentially leading to subtherapeutic levels, while acidic urine can decrease excretion, potentially leading to toxic levels of the drug.
Therefore, monitoring urinary pH helps ensure that Phenytoin levels are within the therapeutic range, minimizing the risk of either subtherapeutic or toxic effects. Monitoring for signs of toxicity, such as ataxia, nystagmus, and confusion, is also essential when administering Phenytoin.
Question 5 of 5
A patient in the outpatient oncology clinic has developed mucositis after receiving fluorouracil. Which statement made by the patient indicates the need for additional teaching about mucositis?
Correct Answer: C
Rationale: Mucositis, inflammation of the mucous membranes, is a common side effect of chemotherapy. Using alcohol-based mouthwash can exacerbate mucositis by causing further irritation and dryness. The patient should be taught to use gentle, non-alcoholic mouth rinses, such as saline or baking soda solutions, to soothe the mucosa. Ice pops, ice chips, and a soft toothbrush are appropriate measures to manage mucositis. The nurse should provide additional teaching to correct the misconception about alcohol-based mouthwash and emphasize the importance of gentle oral care.
