HESI Fundamentals Practice Questions
1. A healthcare professional is caring for a client who has a prescription for a stool specimen to be sent to the laboratory to be tested for ova and parasites. Which of the following instructions regarding specimen collection should the healthcare professional provide to the assistive personnel?
- A. Collect at least 2 inches of formed stool.
- B. Wear sterile gloves while obtaining the specimen.
- C. Use a culturette for specimen collection.
- D. Record the date and time the stool was collected.
Correct answer: A
Rationale: To ensure accurate testing, a minimum amount of stool is required for specimen collection, typically at least 2 inches of formed stool. This amount provides an adequate sample for testing. Wearing sterile gloves is important for infection control but is not specifically required for stool specimen collection. Using a culturette is not typically necessary for collecting stool specimens. Recording the date and time the stool was collected is essential to ensure timely processing but does not directly impact the collection of the specimen itself.
2. When assessing the respiratory system for complications of immobility, what action should the nurse take?
- A. Inspect chest wall movements primarily during the expiratory cycle.
- B. Auscultate the entire lung region to assess lung sounds.
- C. Focus auscultation on the upper lung fields.
- D. Assess the patient at least every 4 hours.
Correct answer: B
Rationale: The correct action for the nurse when assessing the respiratory system for complications of immobility is to auscultate the entire lung region. This approach allows the nurse to identify any diminished breath sounds, crackles, or wheezes that may indicate respiratory issues. Inspecting chest wall movements primarily during the expiratory cycle (Choice A) may not provide a comprehensive assessment of lung sounds. Focusing auscultation on the upper lung fields (Choice C) may miss important findings in the lower lung fields. Assessing the patient at least every 4 hours (Choice D) is important for monitoring overall patient condition but does not specifically address the assessment of respiratory complications related to immobility.
3. Which nursing diagnosis would be a priority for a client admitted with a CVA (cerebral vascular accident)?
- A. Risk for aspiration
- B. Impaired physical mobility
- C. Disturbed sensory perception
- D. Interrupted family processes
Correct answer: A
Rationale: The correct answer is 'Risk for aspiration' as it is a priority concern in clients with a CVA due to potential swallowing difficulties. Aspiration poses immediate risks such as pneumonia, which can be life-threatening. Impaired physical mobility, while important, may not be as urgent as the risk for aspiration in this scenario. Disturbed sensory perception and interrupted family processes are not typically the most critical concerns in the acute phase of a CVA.
4. A client requires gastric decompression, and a nurse is inserting an NG tube. Which action should the nurse take to verify proper placement of the tube?
- A. Assess the client for a gag reflex
- B. Measure the pH of the gastric aspirate
- C. Place the end of the NG tube in water to observe for bubbling
- D. Auscultate 2.5 cm (1 in) above the umbilicus while injecting 15 mL of sterile water
Correct answer: B
Rationale: Measuring the pH of the gastric aspirate is the most reliable method to confirm proper placement of an NG tube. Gastric fluid has an acidic pH, typically ranging from 1 to 5. Assessing the client for a gag reflex (choice A) is important for airway protection but does not confirm tube placement. Placing the NG tube in water to observe for bubbling (choice C) is incorrect and not a reliable method for verifying placement. Auscultating 2.5 cm above the umbilicus while injecting sterile water (choice D) is an outdated method and is not recommended for verifying NG tube placement.
5. When should the nurse plan to collect a sputum specimen for culture and sensitivity as ordered by a client's provider?
- A. In the morning upon rising.
- B. Immediately after the client eats breakfast.
- C. Before the client goes to bed.
- D. After the client has had a drink of water.
Correct answer: A
Rationale: The correct time to collect a sputum specimen for culture and sensitivity is in the morning upon rising. This timing ensures the most concentrated sample as sputum produced overnight tends to accumulate and sit in the airways, providing a quality sample for testing. Collecting the specimen immediately after eating breakfast (choice B) may introduce food particles that could contaminate the sample. Collecting it before bed (choice C) may lead to a diluted sample due to daily activities. Collecting the specimen after having a drink of water (choice D) can also result in a diluted sample, impacting the accuracy of the test results.
