HESI Fundamental Practice Exam
1. When reviewing car seat use with the parents of a 1-month-old infant, which of the following instructions should the nurse include?
- A. Use a car seat that has a three-point harness system.
- B. Position the car seat so that the infant is rear-facing.
- C. Secure the car seat in the front passenger seat of the vehicle.
- D. Convert to a booster seat after 12 months.
Correct answer: B
Rationale: The correct instruction for car seat use with a 1-month-old infant is to position the car seat so that the infant is rear-facing. This orientation provides the safest option for infants as it supports their head, neck, and spine. While using a car seat with a three-point harness system is appropriate for infants, placing the car seat in the front passenger seat is not recommended due to the presence of airbags, which can pose a risk to the infant in the event of deployment. Additionally, transitioning to a booster seat is not suitable at 12 months; infants should remain in rear-facing car seats until they outgrow the seat's height or weight limits, typically around 2 years of age.
2. The nurse is preparing to administer a tuberculin skin test (TST). Which area of the body is the preferred site for this injection?
- A. Deltoid muscle
- B. Inner forearm
- C. Abdomen
- D. Thigh
Correct answer: B
Rationale: The inner forearm is the preferred site for administering a tuberculin skin test (TST) due to its easy accessibility, minimal hair interference, and good visibility of the injection site, allowing for accurate interpretation of the test results. The deltoid muscle, abdomen, and thigh are not preferred sites for a TST as they may not provide the optimal conditions required for the test. The deltoid muscle is commonly used for intramuscular injections, the abdomen may have varying subcutaneous fat thickness affecting the test, and the thigh may not provide the necessary visibility for accurate reading.
3. A nurse is assessing a client with dementia who is showing signs of increased confusion and agitation in the late afternoon. What is the most likely explanation for the client's symptoms?
- A. Anxiety
- B. Depression
- C. Sun-downing syndrome
- D. Medication side effects
Correct answer: C
Rationale: The correct answer is C: Sun-downing syndrome. Sun-downing syndrome is a phenomenon commonly seen in individuals with dementia, where they exhibit increased confusion and agitation in the late afternoon or evening. This pattern of behavior is believed to be linked to disruptions in the circadian rhythm and can be triggered by factors such as fatigue, low lighting, or increased shadows during the evening. Choices A and B, anxiety and depression, may be comorbid conditions in individuals with dementia but are not the primary explanation for the symptoms described. While medication side effects (Choice D) should always be considered in a client with dementia, given the time-specific nature of the symptoms, sun-downing syndrome is the most likely explanation in this case.
4. A client has a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management during the postoperative period following a lumbar laminectomy. Which information should the nurse reinforce about the action of this adjuvant pain modality?
- A. The discharge of electricity will distract the client's focus from the pain
- B. An infusion of medication in the spinal canal will block pain perception
- C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
- D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
Correct answer: D
Rationale: The correct answer is D. TENS works by delivering a mild electrical stimulus to the skin, which can help close the 'gates' in the nervous system to block pain signals from reaching the brain, thus reducing pain perception. Choice A is incorrect because TENS does not distract from pain but rather helps manage it. Choice B is incorrect as it describes a different pain management technique involving medication in the spinal canal. Choice C is incorrect because TENS acts peripherally on nerve conduction rather than dulling pain perception in the cerebral cortex.
5. A 30-year-old sales manager tells the nurse, 'I am thinking about a job change. I don't feel like I am living up to my potential.' Which of Maslow's developmental stages is the sales manager attempting to achieve?
- A. Self-Actualization.
- B. Loving and Belonging.
- C. Basic Needs.
- D. Safety and Security.
Correct answer: A
Rationale: The correct answer is A: Self-Actualization. Self-actualization is the highest level of Maslow's development stages, characterized by the desire to fulfill one's full potential and achieve personal growth. In this scenario, the sales manager's statement indicates a need for personal fulfillment and reaching his highest aspirations, aligning with the concept of self-actualization. Choice B, Loving and Belonging, refers to the need for social relationships and support systems. Choice C, Basic Needs, represents the foundation level of Maslow's hierarchy, encompassing physiological needs like food and shelter. Choice D, Safety and Security, pertains to the need for physical and emotional safety.
