HESI RN
HESI Pharmacology Practice Exam
1. A client taking ethambutol (Myambutol) understands the instructions provided by the nurse if the client states that he or she will immediately report:
- A. Impaired sense of hearing
- B. Problems with visual acuity
- C. Gastrointestinal (GI) side effects
- D. Orange-red discoloration of body secretions
Correct answer: B
Rationale: The correct answer is B: Problems with visual acuity. Ethambutol is known to cause optic neuritis, leading to a decrease in visual acuity and color discrimination. Therefore, any visual changes should be reported promptly to prevent further complications. Choices A, C, and D are incorrect because ethambutol does not typically cause impaired sense of hearing, gastrointestinal side effects, or orange-red discoloration of body secretions. It is crucial for clients taking ethambutol to be aware of potential visual disturbances and report them promptly to healthcare providers.
2. Four days following an abdominal aortic aneurysm repair, the client is exhibiting edema of both lower extremities, and pedal pulses are not palpable. Which action should the nurse implement first?
- A. Elevate extremities on pillows
- B. Evaluate edema for pitting
- C. Assess pulses with a vascular Doppler
- D. Wrap the feet with warmed blankets
Correct answer: C
Rationale: In this scenario, the priority action for the nurse is to assess pulses with a vascular Doppler. The absence of palpable pedal pulses following an abdominal aortic aneurysm repair raises concerns about compromised blood flow, which could lead to serious complications like ischemia or thrombosis. Evaluating and confirming the presence or absence of pulses is crucial to guide further interventions. Elevating extremities on pillows (Choice A) may be beneficial for managing edema, but it is not the immediate priority when pulses are not palpable. Evaluating edema for pitting (Choice B) can provide additional information about fluid status but does not address the primary concern of absent pulses. Wrapping the feet with warmed blankets (Choice D) is not appropriate in this situation and may not address the underlying vascular issue.
3. When giving a report about a client who had a gastrectomy from the intensive care unit to the post-surgical unit nurse, what is the most effective way to assure essential information is reported?
- A. Give the report face-to-face with both nurses in a quiet room.
- B. Audiotape the report for future reference and documentation.
- C. Use a printed checklist with information individualized for the client.
- D. Document essential transfer information in the client's electronic health record.
Correct answer: C
Rationale: Using a printed checklist with individualized information is the most effective way to ensure that all key details about the client who had a gastrectomy are covered during the report. This method helps in structuring the information systematically, reducing the risk of missing important details. Face-to-face communication in a quiet room (Choice A) is important for effective communication but may not guarantee the coverage of all essential information. Audiotaping the report (Choice B) may not be practical for immediate reference or interaction. Documenting in the electronic health record (Choice D) is essential but may not facilitate a comprehensive real-time exchange of information between the nurses.
4. Which foods should a healthcare provider recommend for a child with phenylketonuria (PKU) to avoid?
- A. Fresh fruit and vegetables
- B. Foods sweetened with aspartame
- C. Bread with honey
- D. Gluten-rich bread
Correct answer: B
Rationale: The correct answer is B: 'Foods sweetened with aspartame.' Children with PKU must avoid foods containing aspartame because it breaks down into phenylalanine, which can worsen their condition. Choice A, fresh fruit and vegetables, are generally healthy and safe for individuals with PKU. Choice C, bread with honey, is also safe unless the bread contains artificial sweeteners like aspartame. Choice D, gluten-rich bread, is not specifically problematic for individuals with PKU unless it contains aspartame or other substances high in phenylalanine.
5. When developing a plan of care for a male client admitted with delirium tremens, who is dehydrated, experiencing auditory hallucinations, has a bruised, swollen tongue, and is confused, what action should the RN include to ensure the client is physiologically stable?
- A. Encourage oral fluids.
- B. Monitor vital signs.
- C. Keep the room dark.
- D. Apply ice to his tongue.
Correct answer: B
Rationale: Monitoring vital signs is the priority action to ensure the physiological stability of a client with delirium tremens. In this scenario, the client's dehydration, confusion, and other symptoms necessitate close monitoring of vital signs to assess their condition accurately. Encouraging oral fluids (Choice A) is important for hydration but does not directly assess physiological stability. Keeping the room dark (Choice C) may help with hallucinations but is not the primary intervention for physiological stability. Applying ice to the tongue (Choice D) addresses a symptom but is less critical compared to monitoring vital signs in this situation.
