HESI RN
HESI Pharmacology Practice Exam
1. A client is receiving furosemide (Lasix) and is being discharged. What should the nurse include in the teaching plan?
- A. Consume potassium-rich foods.
- B. Take the medication in the morning.
- C. Change positions slowly to prevent dizziness.
- D. Maintain an adequate fluid intake.
Correct answer: C
Rationale: The correct answer is to instruct the client to change positions slowly to prevent dizziness. Furosemide (Lasix) is a diuretic that can lead to orthostatic hypotension, causing dizziness. Consuming potassium-rich foods is essential to prevent hypokalemia when taking furosemide. Taking the medication in the morning helps reduce the need for frequent urination at night. Encouraging the client to maintain an adequate fluid intake is crucial to prevent dehydration while on this medication.
2. A client in a long-term care facility reports to the nurse that he has not had a bowel movement in 2 days. Which intervention should the nurse implement first?
- A. Instruct the caregiver to offer a glass of warm prune juice at mealtimes.
- B. Notify the healthcare provider and request a prescription for a large-volume enema.
- C. Assess the client's medical record to determine the client's normal bowel pattern.
- D. Instruct the caregiver to increase the client's fluids to five 8-ounce glasses per day.
Correct answer: C
Rationale: When a client reports a change in bowel habits, the first step for the nurse is to assess the client's normal bowel pattern by reviewing the medical records. This assessment helps the nurse understand the client's baseline, which is crucial before initiating any interventions. By determining the client's usual bowel habits, the nurse can identify deviations from the norm and make informed decisions on the appropriate course of action. Assessing the client's medical record is a critical first step in addressing the client's bowel concerns. Choices A, B, and D are incorrect because they jump to interventions without first establishing the client's normal bowel pattern. Offering warm prune juice, requesting a large-volume enema, or increasing fluids may not be appropriate until the nurse knows the client's regular bowel habits and can assess the situation effectively.
3. Which of the following molecules acts as the genetic code's messenger?
- A. RNA
- B. Proteins
- C. DNA
- D. Carbohydrates
Correct answer: A
Rationale: The correct answer is RNA. RNA, particularly mRNA, serves as the messenger that carries genetic information from DNA to the ribosome, where proteins are synthesized. Proteins (choice B) are not the genetic code's messenger; they are synthesized based on the information carried by RNA. DNA (choice C) stores the genetic information but does not directly act as the messenger. Carbohydrates (choice D) are not involved in transmitting genetic information.
4. A preschooler with constipation needs to increase fiber intake. Which snack suggestion should the nurse provide?
- A. Oatmeal cookies
- B. Cheese sticks
- C. Yogurt
- D. Apple slices
Correct answer: A
Rationale: Oatmeal cookies are the best snack suggestion for a preschooler with constipation needing to increase fiber intake. Oatmeal is high in fiber, which helps relieve constipation. Cheese sticks, yogurt, and apple slices are not as high in fiber content as oatmeal and may not be as effective in addressing the constipation issue in this scenario.
5. 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.
