HESI Fundamental Practice Exam

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: B

Rationale: The correct answer is B. The recent administration of opioid analgesics increases the risk for falls due to potential side effects such as sedation and dizziness. Choice A, a recent serum hemoglobin level of 16 g/dL, is not directly related to the risk for falls. Choice C, stooped posture with an unsteady gait, may indicate an existing risk but does not directly reflect the need to include 'Risk for falls' in the care plan. Choice D, expressed feelings of depression, is important to address but is not directly associated with the risk for falls.

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: To ensure proper administration through a nasogastric tube, the LPN/LVN should flush the tube with 30 ml of water before and after medication administration. This action helps ensure the tube is patent, prevents clogging, and helps deliver the medication effectively. Checking the placement of the tube by auscultation (Choice A) is essential but does not directly relate to ensuring proper administration. Administering the medication with food (Choice C) may not always be appropriate for all medications and may not necessarily prevent nausea. Diluting the medication with normal saline (Choice D) is not a standard practice for all medications administered via an NG tube and may alter the medication's effectiveness.

Correct Answer: A

Rationale: Administering oxygen via a nasal cannula is the priority action for a client experiencing chest pain due to coronary artery disease. Oxygen therapy helps improve oxygenation, reduce myocardial workload, and relieve chest pain by increasing oxygen delivery to the heart muscle. While measuring vital signs, obtaining a 12-lead ECG, and encouraging pursed-lip breathing are important interventions, administering oxygen takes precedence in this situation to address the potential hypoxemia associated with chest pain in a client with a history of coronary artery disease.
