HESI Fundamental Practice Exam

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: C

Rationale: The correct answer is C. Taking water pills (diuretics) only when feeling short of breath is incorrect. Diuretics should be taken regularly as prescribed to manage fluid retention. Option A is correct as daily weight monitoring helps track for fluid retention. Option B is correct as worsening leg swelling should prompt contacting the healthcare provider. Option D is correct as limiting salt intake is essential in managing heart failure. Therefore, option C is the statement that indicates a need for further teaching.

Correct Answer: A

Rationale: Wounds healing by secondary intention involve the gradual filling of the wound with granulation tissue, leading to a higher risk of infection due to prolonged exposure. This makes choice A the correct answer. Choices B and C are incorrect because wounds healing by secondary intention take longer to heal and often result in more pain compared to wounds healing by primary intention. Choice D is also incorrect as wounds healing by secondary intention usually require more frequent dressing changes to prevent infection and promote healing.

Correct Answer: B

Rationale: Using a sterile technique throughout the procedure is essential to prevent infection when inserting an IV catheter. This includes maintaining aseptic conditions, using sterile equipment, and following proper hand hygiene practices. Choice A is incorrect because threading the catheter up to the hub does not specifically address infection prevention. Choice C is incorrect as cleaning the insertion site with alcohol only may not provide adequate disinfection, as it is essential to use an antiseptic solution to reduce microbial load. Choice D is incorrect as wearing gloves alone is not sufficient protection against infection; a mask should also be worn to prevent the spread of microorganisms through respiratory secretions.

Correct Answer: A

Rationale: The correct technique for logrolling involves at least three to four people to ensure the safety and proper alignment of the patient's spine. Logrolling requires coordinated effort from multiple individuals to prevent twisting or bending of the spine, hence option A is correct. Option B is incorrect as patients with spinal cord injuries should not be instructed to reach for the opposite side rail due to the risk of causing harm. Option C is incorrect as moving the bottom part of the patient's torso first could lead to spinal misalignment. Option D is incorrect as pillows should be used for support and comfort after the patient has been successfully turned, not before.
