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. The nurse is preparing to administer a medication through a nasogastric (NG) tube. Which action should the LPN/LVN take to ensure proper administration?
- A. Check the placement of the tube by auscultation.
- B. Flush the tube with 30 ml of water before and after medication administration.
- C. Administer the medication with food to prevent nausea.
- D. Dilute the medication with normal saline before administration.
Correct answer: B
Rationale: To ensure proper administration through a nasogastric tube, the LPN/LVN should flush the tube with 30 ml of water before and after medication administration. This action helps ensure the tube is patent, prevents clogging, and helps deliver the medication effectively. Checking the placement of the tube by auscultation (Choice A) is essential but does not directly relate to ensuring proper administration. Administering the medication with food (Choice C) may not always be appropriate for all medications and may not necessarily prevent nausea. Diluting the medication with normal saline (Choice D) is not a standard practice for all medications administered via an NG tube and may alter the medication's effectiveness.
3. The UAP is caring for a male resident of a long-term care facility who has an external urinary catheter. Which finding should the PN instruct the UAP to report immediately?
- A. Swollen and discolored penile shaft
- B. Prepuce extends over the head of the penis
- C. Leaking urine around the top of the catheter
- D. Moist and excoriated perineal skin folds
Correct answer: A
Rationale: The correct answer is A: Swollen and discolored penile shaft. Swelling and discoloration of the penile shaft may indicate an infection or other complications requiring immediate attention. Prompt reporting allows for timely intervention to prevent further harm to the client. Choice B is incorrect because the prepuce extending over the head of the penis is not an urgent issue. Choice C, leaking urine around the catheter, may require intervention but is not as urgent as the swelling and discoloration described in choice A. Choice D, moist and excoriated perineal skin folds, also needs attention but is not as concerning as the potential complications indicated by the findings in choice A.
4. A client who is being discharged to home asks the practical nurse (PN) for a dose of hydrocodone before leaving the hospital. How should the PN respond to this client's request?
- A. Determine if a take-home prescription for hydrocodone was provided and, if so, tell him to take one of them.
- B. Encourage him to wait until he is at home to take a medication that might impair reasoning.
- C. Give him a tablet from the hospital stock and tell him to wait until he is almost home to take it.
- D. Ask him to describe the location and severity of the pain and to rate it on a scale from 1 to 10.
Correct answer: D
Rationale: Hydrocodone is a narcotic analgesic, and the practical nurse should gather more data from the client about the pain he is experiencing before giving the medication. The client's need for pain medication should be addressed, and pain medication should not be withheld because he is going home.
5. The nurse is working on an orthopedic rehabilitation unit that requires lifting and positioning of patients. Which personal injury will the nurse most likely try to prevent?
- A. Arm
- B. Hip
- C. Back
- D. Ankle
Correct answer: C
Rationale: The correct answer is C: Back. Back injuries are common among healthcare workers, especially nurses, due to improper lifting techniques and bending. Working on an orthopedic rehabilitation unit involves frequent lifting and positioning of patients, putting the nurse at risk of back injuries. Preventing back injuries is crucial for maintaining the nurse's health and ability to provide care effectively. Choices A, B, and D are incorrect because while lifting and positioning patients may involve these body parts, back injuries are most likely to occur due to the strain and stress placed on the back during such activities.
