Pharmacology HESI 55 Questions 2023
1. A client with severe rheumatoid arthritis is prescribed methotrexate. The nurse should monitor the client for which potential adverse effect?
- A. Bone marrow suppression
- B. Increased risk of infection
- C. Liver toxicity
- D. Kidney stones
Correct answer: A
Rationale: The correct answer is A: Bone marrow suppression. Methotrexate, commonly used in rheumatoid arthritis, can lead to bone marrow suppression, reducing the production of blood cells and increasing the risk of infection. Monitoring for signs of anemia, leukopenia, and thrombocytopenia is crucial to detect bone marrow suppression early and prevent complications. Choices B, C, and D are incorrect because while methotrexate can increase the risk of infection, liver toxicity, and kidney issues, the primary concern and most significant adverse effect to monitor for is bone marrow suppression due to its impact on blood cell production.
2. A client with hypertension is prescribed lisinopril. The nurse should monitor for which potential side effect?
- A. Dry cough
- B. Hyperkalemia
- C. Hypernatremia
- D. Hyponatremia
Correct answer: A
Rationale: The correct answer is A: Dry cough. Lisinopril, an ACE inhibitor, is known to cause a persistent dry cough as a common side effect. Monitoring for this adverse effect is crucial because it may lead to non-adherence to the medication. Hyperkalemia (choice B) is a potential side effect of potassium-sparing diuretics, not ACE inhibitors like lisinopril. Hypernatremia (choice C) refers to elevated sodium levels and is not a common side effect of lisinopril. Hyponatremia (choice D) is a condition characterized by low sodium levels and is not a typical side effect of lisinopril. Therefore, the nurse should focus on assessing the client for a dry cough when taking lisinopril.
3. How do you determine if the medication is effective for a client with anemia secondary to chronic kidney disease (CKD)?
- A. Food diary shows increased consumption of iron-rich foods
- B. Reports of increased energy levels and decreased fatigue
- C. Hemoglobin level increased to 12 grams/dL
- D. Takes concurrent iron therapy without adverse effects
Correct answer: C
Rationale: The correct answer is C. To assess the effectiveness of medication for anemia in a client with CKD, monitoring hemoglobin levels is crucial. Hemoglobin levels directly indicate the response to treatment and improvement in the condition. An increase in hemoglobin level to 12 grams/dL suggests that the medication is effectively addressing the anemia associated with CKD. Choices A, B, and D are incorrect because increased consumption of iron-rich foods, reports of increased energy levels and decreased fatigue, and tolerance to concurrent iron therapy without adverse effects are not direct indicators of the medication's effectiveness in treating anemia secondary to CKD.
4. What action should be taken six days after starting a prescription for oral amoxicillin solution?
- A. Determine if any other symptoms have developed
- B. Advise the use of over-the-counter antipyretics
- C. Instruct the client to increase oral fluid intake
- D. Ask if the medication has been kept refrigerated
Correct answer: A
Rationale: It is important to monitor for any new symptoms that may indicate a worsening condition or side effects when taking oral amoxicillin solution. This proactive approach helps in assessing the effectiveness and safety of the medication.
5. A client with a history of heart failure is prescribed carvedilol. The nurse should monitor for which potential side effect?
- A. Bradycardia
- B. Tachycardia
- C. Hypertension
- D. Hyperglycemia
Correct answer: A
Rationale: When a client is prescribed carvedilol, the nurse should monitor for bradycardia, a potential side effect of this medication. Carvedilol is a beta-blocker that can slow down the heart rate, so monitoring for signs of bradycardia is essential to prevent any adverse effects on the client's cardiovascular system. Tachycardia (Choice B) is less likely to occur with carvedilol since it primarily works to reduce heart rate. Hypertension (Choice C) and hyperglycemia (Choice D) are not common side effects associated with carvedilol.
