HESI Fundamental Practice Exam

Correct Answer: C

Rationale: Measuring the circumference of the left leg is the most appropriate action for an LPN/LVN when assessing a client with a history of DVT and presenting with swelling and pain in the left leg. This measurement helps to assess the extent of swelling objectively and monitor changes in the client's condition. Applying warm compresses (Choice A) may worsen the condition by potentially promoting clot development. Elevating the left leg above the level of the heart (Choice B) is generally recommended for DVT to improve venous return, but measuring the circumference is more appropriate in this scenario. Administering pain medication (Choice D) does not address the underlying issue and should not be the initial action taken.

Correct Answer: D

Rationale: Crepitus around the chest tube insertion site may indicate subcutaneous emphysema, a serious condition that requires immediate attention. It can be a sign of an air leak in the lung or surrounding tissues. Constant bubbling in the suction control chamber is expected in a functioning chest tube system as it indicates proper suction. Intermittent bubbling in the water seal chamber is also normal, showing that the system is functioning correctly, allowing air to escape but not re-enter. Drainage of 50 ml per hour is within the expected range for chest tube output and does not require immediate intervention unless there are other concerning signs such as rapid increase or a sudden change in color or consistency.

Correct Answer: C

Rationale: The correct action for the nurse to take first is to identify the client's typical bedtime routine. Understanding the client's sleep habits, environment, and bedtime rituals can provide valuable insight into potential factors contributing to their sleep troubles. Teaching stress reduction techniques (choice A) may be beneficial but should come after understanding the client's routine. Recommending avoiding caffeine intake in the evening (choice B) and encouraging regular daytime exercise (choice D) are important interventions, but identifying the bedtime routine takes precedence as it directly addresses the client's immediate concern.

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: When the cerebellum is damaged, it leads to impaired balance. The cerebellum plays a crucial role in coordinating movements and maintaining balance. Therefore, assessing the patient's balance is essential in determining the extent of cerebellar damage. Options B, C, and D are incorrect because hemiplegia refers to paralysis of one side of the body, muscle sprain is a soft tissue injury, and lower extremity paralysis involves loss of function in the lower limbs. These conditions are not directly associated with damage to the cerebellum.
