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. A client with obsessive-compulsive disorder (OCD) repeatedly checks the locks on the doors. What is the most therapeutic nursing intervention?
- A. Allow the client to continue the behavior to reduce anxiety.
- B. Encourage the client to discuss the thoughts and feelings behind the behavior.
- C. Restrict the client's access to the locks.
- D. Schedule specific times for the client to check the locks.
Correct answer: B
Rationale: The most therapeutic nursing intervention for a client with obsessive-compulsive disorder (OCD) who repeatedly checks locks is to encourage the client to discuss the thoughts and feelings behind the behavior. By exploring the underlying anxiety and triggers, the client can work towards understanding and managing their compulsions. Choice A is incorrect because allowing the client to continue the behavior does not address the root cause or help modify the behavior. Choice C is inappropriate as restricting access to locks can increase anxiety and worsen symptoms. Choice D of scheduling specific times for checking locks does not address the underlying psychological issues driving the behavior.
3. When a healthcare professional makes an initial assessment of a client who is post-op following gastric resection, the client's NG tube is not draining. The healthcare professional's attempt to irrigate the tube with 10ml of 0.9% NaCl was unsuccessful, so they determine that the tube was obstructed. Which of the following actions should the healthcare professional take?
- A. Notify the healthcare provider.
- B. Attempt to irrigate the tube with a larger volume of saline.
- C. Replace the NG tube with a new one.
- D. Reposition the client to see if that helps the tube drain.
Correct answer: A
Rationale: If an NG tube is obstructed and cannot be irrigated successfully, notifying the healthcare provider is the appropriate action to take for further management. This is crucial as the healthcare provider may need to assess the situation, provide guidance, or intervene with specific interventions. Attempting to irrigate the tube with a larger volume of saline (Choice B) may exacerbate the situation if the tube is truly obstructed. Replacing the NG tube with a new one (Choice C) should not be the initial action unless advised by the healthcare provider. Repositioning the client (Choice D) may not necessarily resolve the tube obstruction and should not be the primary intervention in this scenario.
4. A nurse is collecting data from an older adult client as part of a neurologic examination. Which of the following findings should the nurse expect as changes associated with aging?
- A. Slower light touch sensation
- B. Some vision and hearing decline
- C. Slower fine finger movement
- D. Some short-term memory decline
Correct answer: B
Rationale: As individuals age, it is common to experience changes in vision and hearing, leading to some decline in these senses. Slower light touch sensation and slower fine finger movement are also typical findings associated with aging. However, some short-term memory decline is more closely related to cognitive aging rather than typical age-related changes in the neurologic system. Therefore, the correct answer is the decline in vision and hearing. Decreased risk of depression is not a typical finding in aging; in fact, the risk of depression may increase as individuals age.
5. Individuals with Klinefelter syndrome produce:
- A. less estrogen than normal males.
- B. less testosterone than normal males.
- C. less adenine than normal males.
- D. less thymine than normal males.
Correct answer: B
Rationale: Individuals with Klinefelter syndrome have an extra X chromosome (XXY), leading to reduced production of testosterone, the primary male sex hormone. This deficiency can result in various physical and developmental characteristics associated with the syndrome. Estrogen levels may actually be relatively elevated due to the imbalance between testosterone and estrogen. Choices C and D are incorrect as adenine and thymine are nucleotide bases found in DNA and are not related to hormone production.
