HESI Fundamental Practice Exam

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.

Correct Answer: A

Rationale: The correct intervention is to assist the client back to bed. A decrease in oxygen saturation while ambulating indicates hypoxemia, and the immediate priority is to stabilize oxygen levels. Returning the client to bed allows for rest and decreased oxygen demand, potentially preventing further desaturation. Encouraging continued ambulation (Choice B) may worsen the hypoxemia by increasing oxygen demand. Obtaining portable oxygen (Choice C) is essential but should not delay addressing the low oxygen saturation. Moving the oximetry probe (Choice D) may not address the underlying cause of decreased oxygen saturation and should not be the first intervention.

Correct Answer: A

Rationale: When providing oral care for an unconscious client, it is essential to place them in a lateral position with the head turned to the side before beginning the procedure. This positioning helps prevent aspiration by allowing fluids to drain out of the mouth, reducing the risk of choking or aspiration pneumonia. Inserting a suction catheter before brushing the teeth (Choice B) is not recommended as it can cause discomfort and increase the risk of oral tissue injury. Using a soft-bristled toothbrush only with water (Choice C) is not sufficient for effective oral care as toothpaste helps in removing plaque and bacteria. Brushing the client's teeth while they are in a supine position (Choice D) is not safe as it increases the risk of aspiration since fluids can easily enter the airway in this position.

Correct Answer: A

Rationale: The correct intervention to minimize the risk for injury in a client with dementia is to use a bed exit alarm system. Bed exit alarms are effective tools to alert healthcare providers when a client attempts to get out of bed, helping prevent falls and injuries. Placing the client in restraints (Choice B) is not the preferred method as it can lead to physical and psychological harm, restrict mobility, and increase agitation. While social interaction is important for clients with dementia, ensuring frequent visitors (Choice C) is not directly related to preventing physical injuries. Keeping the client's room dark and quiet at night (Choice D) may be soothing for some clients but does not directly address the risk for injury associated with dementia.

Correct Answer: B

Rationale: The correct answer is autonomy. Autonomy is the ethical principle that upholds an individual's right to make decisions about their healthcare, including the choice to refuse treatment or surgery. In this scenario, the client's decision not to have surgery despite the recommendation is an exercise of autonomy. Choice A, fidelity, refers to being faithful and keeping promises, which is not applicable in this situation. Choice C, justice, pertains to fair and equal distribution of resources and treatment, not the individual's right to make decisions. Choice D, nonmaleficence, relates to the obligation to do no harm, which is not directly applicable to the client's decision to refuse surgery.
