HESI Fundamentals Practice Questions
1. A nurse is caring for a client receiving fluid through a peripheral IV catheter. Which of the following findings at the IV site should the nurse identify as infiltration?
- A. purulent exudate
- B. warmth
- C. skin blanching
- D. bleeding
Correct answer: C
Rationale: Infiltration occurs when the IV fluid leaks into the surrounding tissue instead of entering the bloodstream properly. Skin blanching, swelling, and coolness at the IV site are typical signs of infiltration. Purulent exudate (choice A) is associated with infection, warmth (choice B) can indicate phlebitis, and bleeding (choice D) may occur if the IV catheter punctures a blood vessel.
2. Why should the nurse closely monitor the IV flow rate for a 5-month-old infant with severe diarrhea receiving IV fluids?
- A. Limiting output
- B. Replacing lost fluids
- C. Avoiding IV infiltration
- D. Preventing cardiac overload
Correct answer: D
Rationale: The correct answer is D: Preventing cardiac overload. Infants are highly vulnerable to fluid overload, making it essential to carefully monitor IV flow rates to prevent complications such as cardiac overload. Rapid administration of IV fluids can lead to an excessive increase in circulating volume, potentially causing cardiac strain or heart failure in infants. Choices A, B, and C are incorrect. Monitoring the IV flow rate is not primarily aimed at limiting output, replacing lost fluids, or avoiding IV infiltration in this scenario. The key concern is to prevent the risk of cardiac overload due to the infant's susceptibility to fluid imbalances.
3. A client with renal disease seems anxious and presents with the onset of shortness of breath, lethargy, edema, and weight gain. Which action should the nurse implement first?
- A. Determine serum potassium level
- B. Calculate the client’s daily fluid intake
- C. Assess client for signs of vertigo
- D. Review the client’s pulse oximetry reading
Correct answer: A
Rationale: The correct answer is to determine the client's serum potassium level. In a client with renal disease experiencing symptoms like shortness of breath, lethargy, edema, and weight gain, assessing serum potassium levels is crucial. Electrolyte imbalances, including potassium, can lead to serious complications such as cardiac arrhythmias and muscle weakness. Calculating daily fluid intake may be important but addressing acute symptoms related to electrolyte imbalances takes precedence. Assessing for signs of vertigo and reviewing pulse oximetry reading are not the priority in this scenario compared to assessing and managing potential electrolyte imbalances.
4. A nurse is planning care for a client who has had a stroke, resulting in aphasia and dysphagia. Which of the following tasks should the nurse assign to an assistive personnel (AP)?
- A. Assist the client with a partial bed bath
- B. Measure the client's BP after the nurse administers an antihypertensive medication
- C. Use a communication board to ask what the client wants for lunch
- D. Feed the client
Correct answer: A
Rationale: In this scenario, the nurse should assign the task of assisting the client with a partial bed bath to an assistive personnel (AP). APs are trained to provide basic care tasks like hygiene assistance. Options B, C, and D involve more complex tasks such as measuring BP, using a communication board for speech-impaired clients, and feeding, which require nursing judgment and skills beyond basic care. Therefore, these tasks should be performed by licensed nursing staff who can assess, communicate effectively, and address the specific medical and safety needs of the client.
5. A 52-year-old male client in the intensive care unit who has been oriented suddenly becomes disoriented and fearful. Assessment of vital signs and other physical parameters reveal no significant change, and the nurse formulates the diagnosis, 'Confusion related to ICU psychosis.' Which intervention would be best to implement?
- A. Move all machines away from the client's immediate area.
- B. Attempt to allay the client's fears by explaining the etiology of his condition.
- C. Cluster care so that brief periods of rest can be scheduled during the day.
- D. Extend visitation times for family and friends.
Correct answer: C
Rationale: In critical care environments, stressors can lead to isolation and confusion. Providing the client with scheduled rest periods (C) can help alleviate these symptoms. Moving all machines away (A) is impractical as they are often essential. Explaining the condition (B) may not be effective during acute confusion. Extending visitation times (D) can be overwhelming for the client in the ICU.
