HESI Fundamentals Study Guide
1. A client is being discharged home with oxygen therapy via a nasal cannula. Which of the following instructions should the nurse provide to the client and family?
- A. Wear cotton clothing to avoid static electricity.
- B. Avoid using any electrical appliances.
- C. Keep the oxygen tank away from heat sources.
- D. Use only a specific type of nasal cannula.
Correct answer: A
Rationale: The correct answer is A: Wear cotton clothing to avoid static electricity. When using oxygen therapy, static electricity can pose a hazard as it increases the risk of fire. Cotton clothing helps reduce static electricity buildup. Choice B, avoiding electrical appliances, is overly restrictive and not entirely necessary. Choice C, keeping the oxygen tank away from heat sources, is important to prevent fire hazards but is not directly related to the nasal cannula. Choice D, using only a specific type of nasal cannula, is not a universal guideline and limits flexibility in care.
2. A nurse is caring for a client who is unstable and has vital signs measured every 15 minutes by an electronic blood pressure machine. The nurse notices the machine begins to measure the blood pressure at varied intervals and the readings are inconsistent. Which of the following actions should the nurse take?
- A. Discontinue the machine and measure the blood pressure manually every 15 minutes.
- B. Adjust the machine settings.
- C. Clean the machine to ensure accuracy.
- D. Increase the frequency of the readings.
Correct answer: B
Rationale: In this scenario, the nurse should adjust the machine settings. If the electronic blood pressure machine is providing varied intervals and inconsistent readings, it indicates a potential malfunction. Changing the settings may help correct the issue and ensure accurate measurements. Discontinuing the machine and measuring manually every 15 minutes (Choice A) may be time-consuming and impractical. Cleaning the machine (Choice C) is important for routine maintenance but may not address the current issue of varied intervals and inconsistent readings. Increasing the frequency of the readings (Choice D) does not address the problem of inaccurate measurements caused by the malfunctioning machine.
3. A client with chronic back pain asks a nurse about receiving acupuncture for relief. Which of the following findings should the nurse identify as a contraindication to receiving this treatment?
- A. Obesity
- B. Hypertension
- C. Migraines
- D. Cellulitis
Correct answer: D
Rationale: The correct answer is D, Cellulitis. Cellulitis is a contraindication for acupuncture due to the risk of infection. Acupuncture involves inserting needles into the skin, and if a person has cellulitis, which is a bacterial skin infection, there is a higher risk of introducing the infection deeper into the body. Obesity (choice A), hypertension (choice B), and migraines (choice C) are not contraindications for receiving acupuncture. These conditions do not pose a direct risk of complications related to acupuncture treatment.
4. At the surgical scrub sink, a surgical nurse demonstrated the proper surgical handwashing technique by scrubbing:
- A. With her hands held lower than her elbows
- B. With her hands held higher than her elbows
- C. With her hands in a fist position
- D. With hands placed on her chest
Correct answer: B
Rationale: The correct technique for surgical handwashing involves scrubbing with hands held higher than the elbows. This positioning helps prevent water from the contaminated area (the hands) from flowing towards the cleaner area (the elbows). This directional flow minimizes the risk of contaminating the scrubbed hands during the handwashing process. Choices A, C, and D are incorrect: A - having hands lower than elbows would risk contamination of the clean area, C - using a fist position does not ensure proper coverage and thorough handwashing, and D - placing hands on the chest is not part of the proper surgical handwashing technique.
5. A healthcare professional is preparing to administer enoxaparin subcutaneously to a client. Which of the following actions should the healthcare professional take?
- A. Administer the medication with the needle at a 45-degree angle.
- B. Administer the medication with the needle at a 90-degree angle.
- C. Inject the medication into the muscle.
- D. Pinch the skin before injecting.
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.
