HESI RN
HESI Pharmacology Practice Exam
1. A healthcare professional is monitoring a client who is receiving intravenous amphotericin B. Which of the following should prompt the healthcare professional to notify the healthcare provider immediately?
- A. Fever
- B. Headache
- C. Nausea
- D. Oliguria
Correct answer: D
Rationale: Amphotericin B is known to cause nephrotoxicity, which can lead to kidney damage. Oliguria, which is decreased urine output, is a concerning sign of kidney dysfunction and should be reported promptly to the healthcare provider to prevent further complications. Fever, headache, and nausea are common side effects of amphotericin B but are not as critical as oliguria in indicating potential kidney damage.
2. What is the difference between saturated and unsaturated fatty acids?
- A. There is no difference between saturated and unsaturated fatty acids.
- B. Saturated fatty acids contain double bonds, unlike unsaturated fatty acids.
- C. Saturated fatty acids often contain two or more pairs of double bonds, unlike unsaturated fatty acids.
- D. Saturated fatty acids contain no double bonds, unlike unsaturated fatty acids.
Correct answer: D
Rationale: The correct answer is D. Saturated fatty acids contain no double bonds between the carbon atoms in their hydrocarbon chains, making them more solid at room temperature. Choice A is incorrect because there is a significant difference between saturated and unsaturated fatty acids. Choice B is incorrect as it inaccurately states that saturated fatty acids contain double bonds, which is a property of unsaturated fatty acids. Choice C is also incorrect as saturated fatty acids do not contain double bonds, let alone two or more pairs of double bonds.
3. An adolescent with a history of bipolar disorder is hospitalized during a manic episode. Which intervention is most appropriate for the nurse to include in the care plan?
- A. Encourage high levels of physical activity.
- B. Provide a quiet and structured environment.
- C. Engage the client in creative arts activities.
- D. Allow the client to make decisions about their schedule.
Correct answer: B
Rationale: During a manic episode, individuals with bipolar disorder may experience heightened energy levels, decreased need for sleep, and racing thoughts. Providing a quiet and structured environment is crucial in managing these symptoms as it helps reduce external stimuli, prevent overstimulation, and promote a sense of calmness. Encouraging high levels of physical activity may exacerbate the manic symptoms by further increasing stimulation and excitement. Engaging the client in creative arts activities might be beneficial during stable periods but may not be the most appropriate intervention during a manic episode. Allowing the client to make decisions about their schedule could potentially lead to impulsivity and poor judgment, which are common characteristics of mania.
4. A client with chronic liver disease is prescribed lactulose. Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?
- A. Bilirubin level
- B. Serum ammonia level
- C. Serum potassium level
- D. Albumin level
Correct answer: B
Rationale: The correct answer is B: Serum ammonia level. Lactulose is used to lower serum ammonia levels in clients with chronic liver disease, particularly in cases of hepatic encephalopathy. Monitoring serum ammonia levels is crucial to evaluate the effectiveness of lactulose in managing hepatic encephalopathy. Choices A, C, and D are incorrect because they are not directly related to the action or evaluation of lactulose in chronic liver disease.
5. An elderly client seems confused and reports the onset of nausea, dysuria, and urgency with incontinence. Which action should the nurse implement?
- A. Auscultate for renal bruits
- B. Obtain a clean catch mid-stream specimen
- C. Use a dipstick to measure for urinary ketones
- D. Begin to strain the client's urine
Correct answer: B
Rationale: This elderly client is presenting symptoms consistent with a urinary tract infection (UTI), such as confusion, nausea, dysuria, urgency, and incontinence. The best course of action for the nurse is to obtain a clean catch mid-stream specimen. This specimen will help identify the causative agent of the UTI, allowing for targeted treatment with an appropriate anti-infective agent. Auscultating for renal bruits (Choice A) is not indicated in this scenario as the client's symptoms point towards a UTI rather than a renal issue. Using a dipstick to measure for urinary ketones (Choice C) is not relevant in the context of UTI symptoms. Beginning to strain the client's urine (Choice D) would not address the need to identify the causative agent for targeted treatment.
