HESI Fundamentals Practice Test
1. During a 30-second interval, the nurse counts six respirations, and the client coughs three times. In repeating the count for a second 30-second interval, the nurse counts eight respirations. What respiratory rate should the nurse document?
- A. 14
- B. 16
- C. 17
- D. 28
Correct answer: B
Rationale: The nurse should document a respiratory rate of 16. The second count of eight respirations in a 30-second interval is the most accurate as it was not interrupted by the client coughing. Therefore, this rate reflects the client's typical respiratory pattern and should be documented. Choices A, C, and D are incorrect as they do not consider the interruption caused by the client coughing during the first count, which could have affected the accuracy of the result. The second count of eight respirations provides a more reliable indication of the client's respiratory rate.
2. The client with chronic obstructive pulmonary disease (COPD) is being taught pursed-lip breathing by the nurse. What is the purpose of this technique?
- A. To promote oxygenation by removing secretions.
- B. To reduce the amount of air trapped in the lungs.
- C. To increase the amount of carbon dioxide exhaled.
- D. To slow the respiratory rate and improve air exchange.
Correct answer: C
Rationale: Pursed-lip breathing is used to increase the amount of carbon dioxide exhaled (C) in clients with chronic obstructive pulmonary disease (COPD). By doing so, it helps prevent air trapping and enhances gas exchange, ultimately improving respiratory efficiency. While removing secretions (A) and reducing air trapping (B) can be associated benefits to some extent, the primary goal of pursed-lip breathing is to optimize carbon dioxide elimination and enhance breathing mechanics. Slowing the respiratory rate (D) is not the primary purpose of pursed-lip breathing.
3. The healthcare professional is using the Glasgow Coma Scale to perform a neurologic assessment. A comatose client winces and pulls away from a painful stimulus. What action should the healthcare professional take next?
- A. Document that the client responds to a painful stimulus.
- B. Observe the client's response to verbal stimulation.
- C. Place the client on seizure precautions for 24 hours.
- D. Report decorticate posturing to the healthcare provider.
Correct answer: A
Rationale: The client's response to a painful stimulus indicates a purposeful reaction, which should be accurately documented as per the assessment findings. This documentation is essential for ongoing monitoring and communication of the client's condition to the healthcare team.
4. The nurse observes an unlicensed assistive personnel (UAP) taking a client's blood pressure with a cuff that is too small, but the blood pressure reading obtained is within the client's usual range. What action is most important for the nurse to implement?
- A. Tell the UAP to use a larger cuff at the next scheduled assessment.
- B. Reassess the client's blood pressure using a larger cuff.
- C. Have the unit educator review this procedure with the UAPs.
- D. Teach the UAP the correct technique for assessing blood pressure.
Correct answer: B
Rationale: The most important action is to ensure that an accurate BP reading is obtained. The nurse should reassess the blood pressure with the correct size cuff (B) to obtain an accurate reading. Postponing reassessment (A) could lead to inaccurate results. While (C and D) are important actions for education and quality improvement, they are not as critical as obtaining an accurate blood pressure reading in this situation.
5. A client is scheduled for a colonoscopy. What instruction should the nurse provide to prepare the client for the procedure?
- A. Drink clear liquids for 24 hours before the procedure
- B. Take a laxative the morning of the procedure
- C. Eat a light meal before the procedure
- D. Avoid drinking fluids for 4 hours before the procedure
Correct answer: A
Rationale: The correct instruction for preparing a client for a colonoscopy is to drink clear liquids for 24 hours before the procedure. This step helps to ensure the bowel is adequately cleared for the colonoscopy, allowing for better visualization and examination of the colon.
