ATI Capstone Pharmacology Assessment 1
1. A client is prescribed spironolactone. Which of the following findings would indicate an adverse effect of this medication?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hyponatremia
- D. Hypernatremia
Correct answer: A
Rationale: Hyperkalemia is the correct answer as it is an adverse effect associated with spironolactone, a potassium-sparing diuretic. Spironolactone works by blocking the aldosterone receptor in the distal convoluted tubule, leading to decreased potassium excretion and potential hyperkalemia. Hypokalemia (choice B) and hyponatremia (choice C) are not typically associated with spironolactone use. Hypernatremia (choice D) is also an unlikely finding with spironolactone.
2. A nurse is preparing to administer ondansetron to a client. Which of the following therapeutic effects should the nurse expect from this medication?
- A. Decreased nausea
- B. Increased appetite
- C. Increased heart rate
- D. Relief of headache
Correct answer: A
Rationale: The correct answer is A: Decreased nausea. Ondansetron is classified as an antiemetic medication, which means it is used to relieve nausea and vomiting by blocking serotonin in the chemoreceptor trigger zone. Therefore, the nurse administering ondansetron should expect a therapeutic effect of decreased nausea. Choice B, increased appetite, is incorrect as ondansetron does not affect appetite. Choice C, increased heart rate, is incorrect as ondansetron does not have a direct effect on heart rate. Choice D, relief of headache, is also incorrect as the primary therapeutic effect of ondansetron is to alleviate nausea and vomiting, not headaches.
3. A nurse is caring for a client who has been prescribed amoxicillin. Which of the following client history findings requires the nurse to clarify the medication prescription?
- A. Hypertension
- B. Peptic ulcer disease
- C. Asthma
- D. Gastroesophageal reflux disease
Correct answer: C
Rationale: The correct answer is C. Clients with a history of asthma should avoid amoxicillin due to potential hypersensitivity reactions. Amoxicillin can trigger asthma exacerbations in some individuals. Hypertension (choice A), peptic ulcer disease (choice B), and gastroesophageal reflux disease (choice D) are not contraindications for amoxicillin use, so they do not require the nurse to clarify the medication prescription in this case.
4. A nurse is caring for a client prescribed methotrexate for rheumatoid arthritis. Which of the following client history findings requires the nurse to question the administration of this medication?
- A. Osteoporosis
- B. Hypertension
- C. Peptic ulcer disease
- D. Immunosuppression
Correct answer: C
Rationale: The correct answer is C: Peptic ulcer disease. Methotrexate can exacerbate peptic ulcer disease, leading to serious complications. This finding warrants questioning the administration of methotrexate to prevent harm to the client. Choices A, B, and D are not directly contraindicated with methotrexate use. Osteoporosis, hypertension, and immunosuppression are not typically reasons to question the administration of methotrexate for rheumatoid arthritis.
5. A nurse is caring for a client who is prescribed warfarin. Which of the following laboratory tests should the nurse review to evaluate the therapeutic effect of this medication?
- A. aPTT
- B. INR
- C. Serum glucose
- D. Bilirubin
Correct answer: B
Rationale: The correct answer is B: INR. The International Normalized Ratio (INR) is the most reliable test for evaluating the therapeutic effects of warfarin therapy. INR measures the clotting ability of the blood and helps determine if the dosage of warfarin is within the therapeutic range. Choice A, aPTT, is not typically used to monitor the effects of warfarin. Choice C, Serum glucose, and choice D, Bilirubin, are not relevant to monitoring the therapeutic effect of warfarin.
