HESI RN
HESI RN Exit Exam 2023
1. A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which laboratory value is most concerning?
- A. Serum potassium of 6.5 mEq/L
- B. Serum bicarbonate of 18 mEq/L
- C. Serum glucose of 350 mg/dl
- D. Serum sodium of 135 mEq/L
Correct answer: A
Rationale: A serum potassium level of 6.5 mEq/L is concerning in a client with COPD exacerbation as it may lead to life-threatening arrhythmias, requiring immediate intervention. Hyperkalemia can cause cardiac arrhythmias, which pose a significant risk to the patient's life. Options B, C, and D are not typically associated with immediate life-threatening risks in the context of a COPD exacerbation.
2. A healthcare provider has written a prescription for ranitidine (Zantac), once daily. When should the nurse schedule the medication?
- A. At bedtime
- B. After lunch
- C. With supper
- D. Before breakfast
Correct answer: A
Rationale: The correct answer is A: At bedtime. Ranitidine should be scheduled at bedtime because it provides a prolonged effect and offers the greatest protection of the gastric mucosa. Administering it at this time helps in managing nocturnal acid breakthrough and providing relief during the night.
3. The healthcare provider is assessing a client with left-sided heart failure. Which laboratory value should be closely monitored?
- A. Serum sodium level
- B. Serum potassium level
- C. Serum creatinine level
- D. Serum glucose level
Correct answer: B
Rationale: In a client with left-sided heart failure, monitoring serum potassium levels is crucial. This helps in assessing kidney function and fluid balance. Elevated potassium levels can result from impaired kidney function, which is common in heart failure. Monitoring sodium levels (choice A) is important in heart failure but not specifically related to left-sided heart failure. Serum creatinine (choice C) reflects kidney function but is not the most critical value to monitor in this case. Serum glucose level (choice D) is important but not the priority when assessing left-sided heart failure.
4. What action should the nurse implement to prepare a client for the potential side effects of a newly prescribed medication?
- A. Assess the client for health alterations that may be impacted by the effects of the medication
- B. Teach the client how to administer the medication to promote the best absorption
- C. Administer a half dose and observe the client for side effects before administering a full dosage
- D. Encourage the client to drink plenty of fluids to promote effective drug distribution
Correct answer: A
Rationale: Before initiating a new medication, the nurse should conduct a thorough assessment of the client to identify any pre-existing health conditions or risk factors that could be affected by the medication. This assessment helps in establishing a baseline for monitoring potential side effects and determining the medication's appropriateness for the client. Choice B is incorrect as teaching the client how to administer the medication does not directly address preparing for potential side effects. Choice C is incorrect because administering a half dose without a proper assessment could be unsafe. Choice D is incorrect as encouraging fluid intake is not directly related to preparing for potential side effects of a medication.
5. An antibiotic IM injection for a 2-year-old child is ordered. The total volume of the injection equals 2.0 ml. The correct action is to
- A. Administer the medication in 2 separate injections
- B. Give the medication in the dorsal gluteal site
- C. Call to get a smaller volume ordered
- D. Check with the pharmacy for a liquid form of the medication
Correct answer: A
Rationale: Injections over 1 mL should be split into two separate injections for young children. This helps in preventing discomfort, ensuring proper absorption, and reducing the risk of tissue damage. Giving the medication in one injection of 2.0 ml might be too much for a 2-year-old child. Choices B and D are incorrect because the dorsal gluteal site is not recommended for children due to potential injury, and changing the form of medication might not be necessary if the volume can be adjusted. Choice C is unnecessary as splitting the dose into two injections is the appropriate action.
