HESI RN
Evolve HESI Medical Surgical Practice Exam
1. A patient has been taking spironolactone (Aldactone) to treat heart failure. The nurse will monitor for
- A. hyperkalemia.
- B. hypermagnesemia.
- C. hypocalcemia.
- D. hypoglycemia.
Correct answer: A
Rationale: The correct answer is A: hyperkalemia. Spironolactone is a potassium-sparing diuretic commonly used in heart failure management. One of the major side effects of spironolactone is hyperkalemia, which is an elevated level of potassium in the blood. Monitoring for hyperkalemia is crucial as it can lead to serious cardiac arrhythmias. Choices B, C, and D are incorrect. Hypermagnesemia (choice B) is not typically associated with spironolactone use. Hypocalcemia (choice C) and hypoglycemia (choice D) are also not directly linked to the use of spironolactone in heart failure treatment.
2. In a patient with asthma, which of the following is the most important indicator of respiratory function?
- A. Oxygen saturation.
- B. Respiratory rate.
- C. Arterial blood gases.
- D. Peak expiratory flow rate.
Correct answer: D
Rationale: The peak expiratory flow rate is the most important indicator of respiratory function in asthma because it measures how quickly air can be exhaled, reflecting the severity of airflow limitation. Oxygen saturation (Choice A) is important in assessing oxygenation, but it does not directly reflect respiratory function. Respiratory rate (Choice B) can provide information on breathing patterns but does not quantify airflow limitation. Arterial blood gases (Choice C) give information about gas exchange but are not as specific for assessing asthma control and severity as peak expiratory flow rate.
3. The charge nurse is planning assignments on a medical unit. Which client should be assigned to the PN?
- A. Test a stool specimen for occult blood
- B. Assist with the ambulation of a client with a chest tube
- C. Irrigate and redress a leg wound
- D. Admit a client from the emergency room
Correct answer: C
Rationale: Irrigating and redressing a leg wound is a common task within the PN's scope of practice, making this assignment appropriate. Tasks like testing stool specimens for occult blood and assisting with ambulation of a client with a chest tube may require a higher level of training and assessment, typically performed by RNs. Admitting a client from the emergency room involves a comprehensive assessment and decision-making process, which is usually within the RN's responsibility.
4. A client who has heart failure is admitted with a serum potassium level of 2.9 mEq/L. Which action is most important for the nurse to implement?
- A. Administer 20 mEq of potassium chloride.
- B. Initiate continuous cardiac monitoring.
- C. Arrange a consultation with the dietitian.
- D. Educate about the side effects of diuretics.
Correct answer: B
Rationale: Hypokalemia, defined as a serum potassium level below the normal range of 3.5 to 5 mEq/L, can lead to changes in myocardial irritability and ECG waveform, potentially causing life-threatening dysrhythmias. Therefore, the priority action for the nurse is to initiate continuous cardiac monitoring to promptly detect any abnormal heart rhythms or ventricular ectopy. This monitoring is crucial for assessing the impact of potassium replacement therapy on the cardiac rhythm and ensuring the safety of the client. While administering potassium chloride is important for correcting the hypokalemia, it should occur after cardiac monitoring is in place. Consulting with a dietitian and educating about diuretic side effects are relevant aspects of care but are not the immediate priority in this situation where cardiac monitoring takes precedence for timely intervention.
5. A client with rheumatoid arthritis is prescribed methotrexate. What is the most important teaching point for the nurse to provide?
- A. Take the medication with food to avoid gastrointestinal upset.
- B. Monitor for signs of infection, such as a sore throat.
- C. Increase fluid intake to prevent dehydration.
- D. Avoid direct sunlight to prevent photosensitivity.
Correct answer: D
Rationale: The most important teaching point for a client prescribed methotrexate is to avoid direct sunlight to prevent photosensitivity. Methotrexate can make the skin more sensitive to sunlight, increasing the risk of sunburn and skin damage. Choices A, B, and C are important aspects of client care but are not specifically related to the side effect of photosensitivity caused by methotrexate.
