HESI Fundamental Practice Exam

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: 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 answer is A because a second nurse should verify and enter the prescription into the client's medical record to ensure accuracy. This step is crucial to prevent errors in transcription and administration. Choice B is incorrect as having another nurse listen to the phone call does not ensure accurate transcription. Choice C is incorrect because the provider clarifying the prescription upon signing the health record does not replace the need for proper documentation. Choice D is incorrect because the 'read back' process is essential for all telephone prescriptions to confirm accuracy and prevent errors in transcription or administration.

Correct Answer: D

Rationale: Including a family member in the teaching session is the most important action for the nurse to implement in this scenario. By involving a family member, the nurse can ensure that there is additional support and reinforcement of the medication plan. This can help the client and family better understand and adhere to the prescribed medications, reducing the client's anxiety. Instructing the client to repeat the medication plan (Choice A) may not address the client's anxiety effectively. Encouraging the client to take a PRN antianxiety drug (Choice B) should not be the first intervention without exploring other supportive measures. Providing written instructions (Choice C) alone may not offer the immediate support and reassurance needed for the anxious client.

Correct Answer: C

Rationale: The correct answer is C: "This test will provide information about the function of your liver." Alanine aminotransferase (ALT) is an enzyme mainly found in the liver. An elevated ALT level may indicate liver damage or disease. Choices A, B, and D are incorrect because ALT is specifically related to liver function and not indicative of blood clot risk, heart performance, or kidney function.
