ATI Capstone Pharmacology Assessment 1 and 2 Questions
Question 1 of 9
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 9
Concentrated solution of sugar in water
Correct Answer: D
Rationale: A concentrated solution of sugar in water is known as a syrup. Syrup is commonly used in cooking and baking to add sweetness and moisture to various dishes. It is created by dissolving sugar in water over heat until a thick, sweet liquid is formed. Syrups are often used in beverages, desserts, and even as a sweetener for certain medications.
Question 3 of 9
“Analgesic, Antipyretic†is an example of :
Correct Answer: B
Rationale: "Analgesic, Antipyretic" describes the pharmacologic class of the drug, indicating that it has pain-relieving (analgesic) and fever-reducing (antipyretic) properties. Pharmacologic class refers to the category or group of medications that have similar pharmacological effects or act on the body in a similar way. In this case, the drug is categorized as an analgesic and antipyretic, which defines its primary therapeutic actions.
Question 4 of 9
Which of the following is a nonsteroidal anti-inflammatory agent with a tendency to produce bone marrow depression?
Correct Answer: D
Rationale: Phenylbutazone is a nonsteroidal anti-inflammatory drug (NSAID) known for its potential to cause bone marrow depression. Bone marrow depression is a serious side effect that can lead to decreased production of blood cells, including white blood cells, red blood cells, and platelets. This can result in an increased risk of infections, anemia, and bleeding disorders. Therefore, phenylbutazone should be used cautiously and under close monitoring to avoid this complication. Aspirin, Colchicine, Ibuprofen, and Acetaminophen are not typically associated with causing bone marrow depression as a side effect.
Question 5 of 9
What is the evaluation of medication effectiveness of senna?
Correct Answer: C
Rationale: Senna is a stimulant laxative commonly used to treat constipation. Its effectiveness is primarily evaluated based on the production of soft, well-formed bowel movements. Senna works by stimulating the muscles in the intestines, promoting bowel movements and easing constipation. It is not typically used for reducing GI pain and irritation, healing ulcers, or preventing nausea and vomiting. Therefore, the evaluation of medication effectiveness of senna is primarily based on achieving soft, formed bowel movements in patients with constipation.
Question 6 of 9
Two tests should be monitored for a patient currently on Warfarin. What are those two tests? Select ALL that apply.
Correct Answer: B
Rationale: 1. INR (International Normalized Ratio): INR is the primary test used to monitor the effectiveness of Warfarin therapy. It measures the clotting tendency of the patient's blood in relation to a standard measurement. The INR target range for patients on Warfarin therapy varies depending on the reason for treatment, but typically falls between 2.0 to 3.0.
Question 7 of 9
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 8 of 9
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.
Question 9 of 9
A patient is in the intensive care unit because of an acute myocardial infarction. He is experiencing severe ventricular dysrhythmias. The nurse will prepare to give which drug of choice for this dysrhythmia?
Correct Answer: C
Rationale: Amiodarone is the drug of choice for treating severe ventricular dysrhythmias, such as those seen in patients with acute myocardial infarction. It is effective in treating both ventricular tachycardia and ventricular fibrillation. Amiodarone works by prolonging the action potential duration and refractory period in cardiac tissues, thereby helping to stabilize the heart's electrical activity. Diltiazem and Verapamil are calcium channel blockers that are not typically used for treating ventricular dysrhythmias. Adenosine is primarily used for treating supraventricular tachycardias.
