HESI Fundamentals Practice Exam

Correct Answer: C

Rationale: In a client with a history of coronary artery disease (CAD) experiencing chest pain, the priority intervention for the nurse to implement first is to apply oxygen via nasal cannula. Oxygenation is crucial to ensure adequate oxygen supply to the tissues and the heart. This intervention takes precedence over administering sublingual nitroglycerin, obtaining an ECG, or initiating continuous cardiac monitoring. While these interventions are important, ensuring adequate oxygenation is the initial priority in the management of a client with chest pain.

Correct Answer: B

Rationale: Repositioning the client's arm is the initial action to take when encountering an obstruction with an antecubital saline lock. Repositioning may correct any bending at the elbow that could be causing the obstruction, allowing for smoother infusion flow. Checking for a blood return, removing the IV site dressing, or flushing the lock with saline would be subsequent actions once the obstruction is addressed. Checking for a blood return is done to confirm proper placement, removing the IV site dressing is necessary for site assessment, and flushing the lock with saline helps maintain patency but should not be the first action when an obstruction is detected.

Correct Answer: C

Rationale: To maintain patency and ensure proper medication delivery, water should be instilled into the feeding tube between administering the two medications. This helps prevent clogging of the tube and ensures that both medications are delivered effectively without interference from remnants of the previous medication. Diluting the medications with sterile water before administration (choice A) is unnecessary and may alter the medication concentration. Mixing the medications in one syringe (choice B) could lead to interactions or chemical reactions between the medications. Withdrawing fluid from the tube before instilling each medication (choice D) is not required and may increase the risk of tube displacement or misplacement.

Correct Answer: B

Rationale: The correct position for the drainage container after inserting an indwelling catheter is to have it placed lower than the bladder. This positioning helps maintain a constant downward flow of urine from the bladder, preventing backflow and ensuring proper drainage. Choice A is incorrect because having the drainage tubing taut does not promote proper urine flow and may cause kinking. Choice C is incorrect as placing the container at the head of the bed does not affect drainage and is not necessary for accurate measurement. Choice D is incorrect as the positioning of the drainage container should prioritize proper drainage and care over potential embarrassment.

Correct Answer: C

Rationale: It is essential for clients using herbal therapies to obtain herbs from manufacturers with a history of quality control for their supplements. This recommendation is crucial because quality control processes help in maintaining the purity and effectiveness of the herbal supplements. Option A is incorrect as it provides a negative and inaccurate generalization about herbs. Option B is also incorrect as there is existing evidence on the safety and efficacy of certain herbal supplements. Option D is not the most relevant information to offer initially to a client seeking advice on the general use of herbal supplements.
