HESI Fundamentals Study Guide
1. 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?
- A. “I will be sure to remove my hearing aid before taking a shower.”
- B. “I will keep my hearing aid in at all times, even when sleeping.”
- C. “I will clean my hearing aid with alcohol.”
- D. “I will turn off my hearing aid when not in use.”
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.
2. A client is scheduled for an IVP (Intravenous Pyelogram). Which of the following data from the client's history indicates a potential hazard for this test?
- A. Reflex incontinence
- B. Allergic to shellfish
- C. Claustrophobia
- D. Hypertension
Correct answer: B
Rationale: The correct answer is B, 'Allergic to shellfish.' An allergy to shellfish can indicate a sensitivity to iodine, which is used in the contrast dye for an IVP, posing a risk of an allergic reaction. Reflex incontinence (Choice A) is not directly related to the potential hazard of an IVP. Claustrophobia (Choice C) and hypertension (Choice D) are also not significant factors that indicate a potential hazard for an IVP.
3. Which of the following statements about CHN is wrong?
- A. CHN synthesizes public health with nursing
- B. CHN emphasizes health
- C. Promoting clients' autonomy is a responsibility of public nursing
- D. CHN makes a unique contribution to health care not by the nature of its practice but where it is practiced
Correct answer: D
Rationale: The statement in option D is incorrect. The unique contribution of Community Health Nursing (CHN) is not only where it is practiced but also by the nature of its practice. CHN's distinct value lies in its approach to care delivery, focusing on preventive care, health promotion, and addressing the needs of specific communities. Options A and B are correct as CHN involves synthesizing public health principles with nursing practice and emphasizes holistic health. Option C is incorrect as promoting clients' autonomy is a fundamental aspect of community health nursing, respecting individuals' rights to make decisions about their health.
4. A nurse is preparing to administer ketorolac 0.5 mg/kg IV bolus every 6 hr to a school-age child who weighs 66 lb. The available ketorolac injection is 30 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
- A. 0.5 mL
- B. 1 mL
- C. 1.5 mL
- D. 2 mL
Correct answer: A
Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg ÷ 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.
5. The wife of a client with Parkinson's disease expresses concern because her husband has lost so much weight. Which teaching is best for the nurse to provide?
- A. Invite friends over regularly to share meal times
- B. Encourage the client to drink clear liquids between meals
- C. Coach the client to make an intentional effort to swallow
- D. Talk to the healthcare provider about prescribing an appetite stimulant
Correct answer: A
Rationale: The best teaching for the nurse to provide is to invite friends over regularly to share meal times. This can help in making meal times more enjoyable for the client with Parkinson's disease, potentially encouraging him to eat more. Encouraging clear liquids between meals (choice B) may not address the underlying issue of weight loss. Coaching the client to make an intentional effort to swallow (choice C) may not be effective if the weight loss is due to other factors related to Parkinson's disease. While prescribing an appetite stimulant (choice D) could be an option, it is usually recommended to explore non-pharmacological interventions first, making choice A the most appropriate initial teaching intervention.
