HESI Fundamentals Practice Questions

Correct Answer: A

Rationale: Identifying the client using two identifiers is the crucial first step to ensure correct patient identification before any procedure. This process helps prevent errors and ensures that the right procedure is performed on the right patient. Confirming the client's identity is the top priority before addressing other aspects such as fasting status, allergies, or explaining the procedure. While confirming fasting status and checking for allergies are important, they are secondary to confirming the client's identity. Explaining the procedure to the client is also essential but should occur after ensuring proper identification.

Correct Answer: B

Rationale: In a client with septicemia, decreased blood pressure is a critical finding that suggests potential septic shock, a life-threatening condition. Septic shock requires immediate medical intervention to prevent further deterioration and organ dysfunction. Increased urine output (Choice A) may indicate adequate fluid resuscitation, which is a positive response. Increased heart rate (Choice C) and increased respiratory rate (Choice D) are common physiological responses to sepsis and do not necessarily indicate immediate life-threatening complications like decreased blood pressure does in septic shock.

Correct Answer: B

Rationale: The correct answer is B: Obtain a class C fire extinguisher to extinguish the fire. Using a class C fire extinguisher is appropriate for electrical fires, which can include fires involving electrical equipment or appliances. In this scenario, a paper fire in a trash can in the client's bathroom could potentially involve electrical components, making a class C fire extinguisher the most suitable choice. Option A, opening the windows, may help with ventilation but does not address the fire directly. Option C, removing electrical equipment, is a precautionary measure but does not address the immediate fire hazard. Option D, placing wet towels along the base of the door, is a strategy to prevent smoke from entering the room but does not extinguish the fire.

Correct Answer: A

Rationale: Montgomery straps are the correct choice in this scenario. They are specifically designed to secure dressings around drain sites, like Penrose drains, and are ideal for frequent dressing changes. Sterile gauze (Choice B) is commonly used for wound dressings but may not provide the best securement for drains. Adhesive tape (Choice C) can cause skin irritation and may not be suitable for securing drains. Elastic bandages (Choice D) are typically used for compression or support but are not appropriate for securing dressings around drain sites.

Correct Answer: B

Rationale: A peak flow meter is used to measure forced expiratory volume, which helps in monitoring asthma. This measurement provides valuable information about how well the client's lungs are functioning and how narrow their airways are. Choice A is incorrect because determining oxygen saturation is typically done using a pulse oximeter. Choice C is incorrect as a peak flow meter is not used to monitor the atmosphere for allergens but rather to assess lung function. Choice D is incorrect as providing metered doses for inhaled bronchodilators is the function of a metered-dose inhaler, not a peak flow meter.
