HESI Fundamentals Practice Questions
1. When reviewing EBP about the administration of O2 therapy, what is the recommended maximum flow rate for regulating O2 via nasal cannula?
- A. Regulate O2 via nasal cannula no more than 6L
- B. Regulate O2 via nasal cannula no more than 2L
- C. Regulate O2 via nasal cannula no more than 4L
- D. Regulate O2 via nasal cannula no more than 8L
Correct answer: A
Rationale: The correct answer is to regulate O2 via nasal cannula no more than 6L. This flow rate is generally recommended to ensure adequate oxygen delivery without causing discomfort or potential harm to the patient. Choices B, C, and D are incorrect as they suggest flow rates that are either too low (2L, 4L) or too high (8L). A flow rate of 2L might not provide sufficient oxygen, while 4L could be inadequate for some patients. On the other hand, a flow rate of 8L could be excessive and potentially harmful, leading to complications like oxygen toxicity. Therefore, the optimal recommendation is to regulate O2 via nasal cannula at a maximum of 6L to balance effectiveness and safety.
2. An adult client is found to be unresponsive during morning rounds. After checking for responsiveness and calling for help, what should the nurse do next?
- A. Check the carotid pulse
- B. Deliver 5 abdominal thrusts
- C. Give 2 rescue breaths
- D. Open the client's airway
Correct answer: D
Rationale: After confirming unresponsiveness and calling for help, the next step in basic life support is to open the client's airway. This ensures that the airway is clear and allows for effective ventilation. Checking the carotid pulse is not necessary at this stage as airway management takes precedence. Delivering abdominal thrusts is not indicated for an unresponsive client as it is for conscious choking individuals. Giving rescue breaths should only be done after ensuring the airway is open to allow for effective ventilation.
3. To evaluate a client's understanding of self-administering insulin within the psychomotor domain of learning, what action should the instructor take?
- A. Have the client demonstrate the procedure.
- B. Explain the procedure again.
- C. Ask the client to describe the procedure.
- D. Observe the client watching a video on the procedure.
Correct answer: A
Rationale: Having the client demonstrate the procedure is the most appropriate action to evaluate understanding within the psychomotor domain of learning. This allows the instructor to assess the client's ability to perform the skill, which is a key aspect of this domain. Choice B, explaining the procedure again, focuses on the cognitive domain rather than the psychomotor domain. Choice C, asking the client to describe the procedure, pertains more to the verbal or cognitive domain of learning. Choice D, observing the client watching a video on the procedure, does not directly assess the client's ability to perform the skill in the psychomotor domain.
4. A nurse is planning care for a client who reports abdominal pain. An assessment by the nurse reveals the client has a temperature of 39.2°C (102°F), heart rate of 105/min, a soft tender abdomen, and menses overdue by 2 days. Which of the following findings should be the nurse’s priority?
- A. Temperature
- B. Menses overdue
- C. Soft tender abdomen
- D. Heart rate
Correct answer: A
Rationale: The correct answer is A: Temperature. A high temperature of 39.2°C (102°F) indicates a fever, which can be a sign of infection or another serious condition. Investigating the cause of the fever is a priority to address any underlying health issue promptly. Menses overdue (choice B) could be relevant but is not as urgent as addressing a fever. A soft tender abdomen (choice C) is important but may be a consequence of the underlying condition causing the fever. Heart rate (choice D) is also significant, but the priority here is to identify the cause of the fever.
5. A healthcare professional is preparing to administer lactated Ringer's (LR) IV 100 mL over 15 min. How many mL/hr should the IV infusion pump be set to deliver? (Round the answer to the nearest whole number. Do not use a trailing zero.)
- A. 400 mL/hr
- B. 200 mL/hr
- C. 300 mL/hr
- D. 250 mL/hr
Correct answer: A
Rationale: To administer 100 mL over 15 min, the IV pump should be set to deliver 400 mL/hr. This calculation is based on the concept that if 100 mL is given in 15 minutes, to find out how many milliliters are given in an hour, you would multiply by 4 (since 15 minutes is a quarter of an hour). Therefore, 100 mL x 4 = 400 mL per hour. Choices B, C, and D are incorrect as they do not reflect the correct calculation for the infusion rate required to administer 100 mL over 15 minutes.
