HESI Fundamental Practice Exam

Correct Answer: C

Rationale: The correct answer is C: 'I should use a soft-bristled toothbrush while taking this medication.' Using a soft-bristled toothbrush is crucial as it helps prevent bleeding gums, which is a potential side effect of warfarin therapy. Option A about taking warfarin at the same time every day is a good practice but does not directly relate to preventing side effects. Option B suggesting an increase in green leafy vegetables can interfere with warfarin's anticoagulant effects due to their vitamin K content. Option D advising to avoid alcohol is generally recommended but is not directly related to the specific side effects of warfarin.

Correct Answer: A

Rationale: Correct! Written consent is required for procedures that carry significant risks, such as blood transfusions, to ensure the client's informed consent and understanding of the procedure. In this case, a transfusion of packed red blood cells is an invasive procedure that carries risks, making it essential to have the client's written consent. Choices B, C, and D do not typically require written consent as routine physical examinations, minor surgical procedures without anesthesia, and new medication prescriptions do not carry the same level of risk and complexity as a blood transfusion.

Correct Answer: A

Rationale: Placing a pillow under the patient's lower legs when in the prone position is essential to allow dorsiflexion of the ankles and some knee flexion, which promote relaxation. This position also helps in maintaining proper alignment of the spine. Options B, C, and D are incorrect because turning the head, positioning legs flat against the bed, and raising the head of the bed to 45 degrees are not appropriate actions for a patient in the prone position. Turning the head to one side with a large, soft pillow is commonly done for patients in the supine position to maintain proper alignment and airway patency. Positioning legs flat against the bed is more suitable for a patient in a supine or semi-fowler's position. Raising the head of the bed to 45 degrees is typically done for patients who need semi-fowler's positioning for respiratory support or to prevent aspiration.

Correct Answer: B

Rationale: The correct answer is B because the ability to demonstrate the appropriate technique shows that the client has acquired the psychomotor skills needed for insulin preparation. Merely discussing, stating an understanding, or writing the steps does not confirm that the client can physically perform the task correctly. Being able to demonstrate indicates practical application and mastery of the skill. Choice A is incorrect because discussing the technique does not necessarily mean the client can physically perform it. Choice C is incorrect as stating an understanding does not guarantee the client's ability to perform the task. Choice D is incorrect because writing the steps does not assess the client's physical execution of the technique.

Correct Answer: A

Rationale: The correct action to maintain patency of a nasogastric (NG) tube is to flush the tube with water before and after medication administration. Flushing helps prevent clogging and ensures that the tube remains clear for proper functioning. Securing the tube to the client's gown (Choice B) is important for stability but does not directly address tube patency. Checking the placement of the tube by auscultation (Choice C) is crucial for verifying correct placement but does not specifically relate to maintaining tube patency. Irrigating the tube with normal saline every shift (Choice D) is not a routine practice for maintaining tube patency and can lead to electrolyte imbalances.
