Evolve HESI Medical Surgical Practice Exam Quizlet
1. The client with peripheral vascular disease (PVD) and a history of heart failure may have a low tolerance for exercise due to:
- A. Decreased blood flow.
- B. Increased blood flow.
- C. Decreased pain.
- D. Increased blood viscosity.
Correct answer: A
Rationale: The correct answer is A: Decreased blood flow. In clients with peripheral vascular disease (PVD) and a history of heart failure, decreased blood flow due to heart failure can result in reduced oxygen delivery to tissues. This reduced oxygen supply can lead to low exercise tolerance. Increased blood flow (Choice B) is not typically associated with reduced exercise tolerance in these clients. Decreased pain (Choice C) and increased blood viscosity (Choice D) are not the primary factors contributing to low exercise tolerance in this scenario.
2. A client with diabetes mellitus is scheduled for surgery, and their blood glucose level is 280 mg/dL. What is the nurse's priority action?
- A. Administer insulin as prescribed.
- B. Delay surgery until the blood glucose is below 180 mg/dL.
- C. Check the client’s hemoglobin A1C level.
- D. Administer IV fluids to flush excess glucose.
Correct answer: A
Rationale: The correct answer is A: Administer insulin as prescribed. In clients with diabetes, high blood glucose levels can increase the risk of infection and impair healing after surgery. Administering insulin as prescribed helps reduce blood glucose to a safer level before surgery, preventing complications. Choice B is incorrect because delaying surgery without addressing the high blood glucose level does not address the immediate issue. Choice C is incorrect as checking the client's hemoglobin A1C level is not the priority when dealing with acute high blood glucose levels before surgery. Choice D is incorrect as administering IV fluids may help with hydration but does not directly address the high blood glucose level that needs immediate attention.
3. When assisting a client with right-sided hemiplegia to get into a wheelchair, how should the nurse position the wheelchair?
- A. On the left side of the bed facing the foot of the bed.
- B. On the right side of the bed facing the head of the bed.
- C. Perpendicular to the bed on the right side.
- D. Facing the bed on the left side of the bed.
Correct answer: A
Rationale: Positioning the wheelchair on the left side of the bed facing the foot of the bed is the correct approach when assisting a client with right-sided hemiplegia. Placing the wheelchair on the left side allows the client to stand on their unaffected foot and pivot to sit down safely. This positioning facilitates a smoother transfer and helps maintain the client's stability during the process. Choice B is incorrect because positioning the wheelchair on the right side facing the head of the bed would make it challenging for the client to transfer due to their right-sided hemiplegia. Choice C is incorrect as placing the wheelchair perpendicular to the bed on the right side may not provide the necessary space and angle for a safe transfer. Choice D is incorrect as facing the bed on the left side of the bed does not provide the optimal position for the client to transfer from the bed to the wheelchair effectively.
4. Polyethylene glycol–electrolyte solution (GoLYTELY) is prescribed for a hospitalized client scheduled for a colonoscopy. The client begins to experience diarrhea after drinking the solution. Which action by the nurse is appropriate?
- A. Calling the physician
- B. Administering a cleansing enema
- C. Documenting the diarrhea in the medical record
- D. Giving intravenous replacement fluids in large amounts
Correct answer: C
Rationale: The correct action by the nurse in this situation is to document the diarrhea in the medical record. Polyethylene glycol–electrolyte solution (GoLYTELY) is a bowel evacuant used to cleanse the bowel before a colonoscopy. It is expected to cause mild diarrhea, which is a normal response to the medication. The diarrhea helps clear the bowel in preparation for the procedure. Calling the physician is not necessary unless there are complications. Administering a cleansing enema or giving intravenous replacement fluids in large amounts are not appropriate actions as they are not indicated for managing the expected diarrhea caused by GoLYTELY.
5. Which of the following best describes phenotype?
- A. The hereditary potentials and limitations of an individual
- B. The genetic makeup of an individual organism
- C. The entire complex of genes inherited from both parents
- D. All the observable characteristics of an organism
Correct answer: D
Rationale: The correct answer is D: 'All the observable characteristics of an organism.' Phenotype refers to all the observable characteristics of an organism, such as physical appearance, behavior, and other traits, which result from the interaction of its genotype with the environment. Choice A is incorrect because it describes genotype. Choice B is incorrect as it defines genotype, not phenotype. Choice C is incorrect as it refers to the genotype, the genetic information inherited from both parents, rather than the observable traits.
