HESI Fundamentals Study Guide Questions
Question 1 of 5
A healthcare professional is preparing to administer enoxaparin subcutaneously to a client. Which of the following actions should the healthcare professional take?
Correct Answer: B
Rationale: Enoxaparin is a medication that is administered subcutaneously, which means it should be injected into the fatty tissue layer beneath the skin. Administering enoxaparin at a 90-degree angle ensures proper absorption and reduces the risk of injecting the medication into muscle tissue, which could affect its effectiveness. Injecting the medication at a 45-degree angle may lead to improper absorption as it may not reach the subcutaneous tissue adequately. Injecting the medication into the muscle instead of subcutaneously can alter the absorption rate and therapeutic effects. Pinching the skin before injecting is not necessary for administering enoxaparin subcutaneously and may cause unnecessary discomfort to the client.
Question 2 of 5
A client who has recently started using a behind-the-ear hearing aid is being cared for by a nurse. Which of the following statements should the nurse identify as an indication that the client understands the use of assistive devices?
Correct Answer: A
Rationale: The correct answer is A. It is crucial for the client to remove the hearing aid before showering to prevent damage from moisture. Choice B is incorrect as wearing the hearing aid all the time, including during sleep, is not recommended and can cause discomfort or harm. Choice C is incorrect as alcohol can damage hearing aids; they should be cleaned with a solution recommended by the manufacturer to prevent harm. Choice D is incorrect because hearing aids should not be turned off when not in use; instead, they should be stored properly following the manufacturer's instructions to maintain functionality and battery life.
Question 3 of 5
A nurse in an emergency department is assessing a client who reports diarrhea and decreased urination for 4 days. Which of the following actions should the nurse take to assess the client's skin turgor?
Correct Answer: A
Rationale: To assess skin turgor, the nurse should grasp a skin fold on the chest under the clavicle, release it, and note whether it springs back. This method is preferred for older adults and in cases of significant fluid imbalance. Option B is incorrect as assessing skin turgor on the back of the hand is not the standard assessment site for skin turgor. Option C is incorrect as the abdomen is not the typical area for assessing skin turgor; the chest under the clavicle is a more accurate site. Option D is incorrect as pressing on the forearm is not the appropriate site for evaluating skin turgor; the chest under the clavicle is the recommended location for this assessment.
Question 4 of 5
A client is admitted for evaluation and control of HTN. Several hours after the client's admission, the nurse discovers the client supine on the floor, unresponsive to verbal or painful stimuli. The nurse's first reaction at this time is to:
Correct Answer: A
Rationale: In a situation where a client is found unresponsive on the floor, the nurse's first priority is to establish an airway. This is crucial to ensure that the client can breathe adequately and receive oxygen. Without a patent airway, the client's oxygenation and ventilation may be compromised, leading to serious consequences. Calling for assistance is important, but establishing an airway takes precedence as it directly impacts the client's ability to breathe. Checking the client's pulse and blood pressure can be done after ensuring a clear airway. Performing CPR is not the immediate action needed unless the client's breathing and pulse are absent after the airway has been secured.
Question 5 of 5
A healthcare professional is preparing to insert an NG tube for a client admitted with bowel obstruction. Which of the following should the healthcare professional do first?
Correct Answer: A
Rationale: Explaining the procedure to the client is the initial and most important step that the healthcare professional should take before inserting an NG tube. By explaining the procedure, the healthcare professional ensures the client's understanding, obtains informed consent, and fosters cooperation. Measuring the length of the NG tube, lubricating the tube, and positioning the client in a high Fowler's position are essential steps in the NG tube insertion process but should come after the client has been informed and consented to the procedure.
