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 healthcare provider obtains a BP reading of 100/88 in the right arm of a client whose blood pressure is typically 120/60 in the same arm. What action should the healthcare provider implement first?
- A. Use an electronic sphygmomanometer to take the BP every 30 minutes.
- B. Retake the blood pressure in the same arm, deflating the cuff slowly.
- C. Ask another healthcare provider to recheck the blood pressure to compare results.
- D. Obtain another blood pressure cuff and retake the blood pressure.
Correct answer: B
Rationale: The healthcare provider should first retake the blood pressure in the right arm, deflating the cuff slowly, because a low systolic and high diastolic blood pressure measurement is often the result of deflating the cuff too rapidly. Taking the BP in the same arm ensures consistency and accuracy of the measurement.
3. The healthcare professional is preparing to administer 10 mL of liquid potassium chloride through a feeding tube, followed by 10 mL of liquid acetaminophen. Which action should the healthcare professional include in this procedure?
- A. Dilute each of the medications with sterile water prior to administration.
- B. Mix the medications in one syringe before opening the feeding tube.
- C. Administer water between the doses of the two liquid medications.
- D. Withdraw any fluid from the tube before instilling each medication.
Correct answer: C
Rationale: To maintain patency and ensure proper medication delivery, water should be instilled into the feeding tube between administering the two medications. This helps prevent clogging of the tube and ensures that both medications are delivered effectively without interference from remnants of the previous medication. Diluting the medications with sterile water before administration (choice A) is unnecessary and may alter the medication concentration. Mixing the medications in one syringe (choice B) could lead to interactions or chemical reactions between the medications. Withdrawing fluid from the tube before instilling each medication (choice D) is not required and may increase the risk of tube displacement or misplacement.
4. When caring for an immobile client, what nursing diagnosis has the highest priority?
- A. Risk for fluid volume deficit.
- B. Impaired gas exchange.
- C. Risk for impaired skin integrity.
- D. Altered tissue perfusion.
Correct answer: B
Rationale: When caring for an immobile client, the nursing diagnosis with the highest priority is impaired gas exchange. This is because impaired gas exchange implies difficulty with breathing, which is essential for sustaining life. Adequate oxygenation is crucial for all bodily functions, and any impairment in gas exchange can lead to serious complications, making it the priority nursing diagnosis to address in an immobile client. Choices A, C, and D are important considerations as well when caring for an immobile client, but they are secondary to impaired gas exchange. Risk for fluid volume deficit may occur due to immobility, but ensuring proper gas exchange takes precedence as it directly impacts the client's immediate survival. Risk for impaired skin integrity is a concern in immobile clients but does not pose an immediate threat to life like impaired gas exchange. Altered tissue perfusion is also critical but is usually a consequence of impaired gas exchange, reinforcing the priority of addressing gas exchange first.
5. A client with a diagnosis of asthma is receiving albuterol (Proventil) via a metered-dose inhaler (MDI). Which assessment finding indicates that the medication is effective?
- A. Increased oxygen saturation.
- B. Decreased respiratory rate.
- C. Absence of audible wheezing.
- D. Improved exercise tolerance.
Correct answer: A
Rationale: Increased oxygen saturation (A) is the most direct indicator of the effectiveness of albuterol (Proventil) in improving breathing. Oxygen saturation reflects the amount of oxygen in the blood, showing that the albuterol is helping with air exchange in the lungs. While decreased respiratory rate (B), absence of audible wheezing (C), and improved exercise tolerance (D) are positive outcomes, they are secondary to oxygen saturation. Oxygen saturation directly reflects the improvement in the client's respiratory status and the effectiveness of the medication.
