HESI Medical Surgical Practice Exam Quizlet
1. In a 46-year-old female client admitted for acute renal failure secondary to diabetes and hypertension, which test is the best indicator of adequate glomerular filtration?
- A. Serum creatinine.
- B. Blood urea nitrogen (BUN).
- C. Sedimentation rate.
- D. Urine specific gravity.
Correct answer: A
Rationale: The correct answer is A: Serum creatinine. Creatinine is a product of muscle metabolism that is filtered by the glomerulus. Blood levels of creatinine are not affected by dietary or fluid intake, making it a reliable indicator of kidney function. An elevated creatinine level strongly suggests nephron loss, indicating decreased glomerular filtration rate. Choice B, Blood Urea Nitrogen (BUN), reflects the amount of urea nitrogen in the blood and can be influenced by factors other than kidney function, such as protein intake and liver health, making it less specific for evaluating glomerular filtration. Choice C, Sedimentation rate, is a measure of how quickly red blood cells settle in a test tube and is not a direct marker of kidney function. Choice D, Urine specific gravity, mainly reflects the kidney's ability to concentrate urine and is not a direct indicator of glomerular filtration rate. Therefore, Serum creatinine is the most appropriate test to assess glomerular filtration in this scenario.
2. To prevent unnecessary hypoxia during suctioning of a tracheostomy, what must the nurse do?
- A. Apply suction for no more than 10 seconds
- B. Maintain sterile technique
- C. Lubricate 3 to 4 inches of the catheter tip
- D. Withdraw catheter in a circular motion
Correct answer: A
Rationale: The correct answer is to apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia, so it is essential to limit the suctioning time. Maintaining sterile technique (choice B) is important to prevent infections but is not directly related to preventing hypoxia during suctioning. Lubricating the catheter tip (choice C) helps with insertion but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not help prevent hypoxia.
3. An adult who was recently diagnosed with glaucoma tells the nurse, 'it feels like I am driving through a tunnel.' The client expresses great concern about going blind. Which nursing instruction is most important for the nurse to provide this client?
- A. Maintain prescribed eye drop regimen
- B. Avoid frequent eye pressure measurements
- C. Wear prescription glasses
- D. Eat a diet high in carotene
Correct answer: A
Rationale: The correct answer is A: Maintain prescribed eye drop regimen. In glaucoma, maintaining the prescribed eye drop regimen is crucial for controlling intraocular pressure, which helps in preventing vision loss. Consistent use of eye drops as directed can slow down the progression of the disease and preserve vision. Choice B is incorrect because avoiding frequent eye pressure measurements does not address the primary treatment for glaucoma. Choice C is incorrect as wearing prescription glasses may be helpful for vision correction but does not directly address the management of glaucoma. Choice D is incorrect because while a diet high in carotene may promote overall eye health, it is not the most important instruction for managing glaucoma.
4. During a routine assessment, an obese 50-year-old female client expresses concern about her sexual relationship with her husband. Which is the best response by the nurse?
- A. Reassure the client that many obese individuals have concerns about sex.
- B. Remind the client that sexual relationships can be maintained regardless of weight.
- C. Determine the frequency of sexual intercourse.
- D. Ask the client to talk about specific concerns.
Correct answer: D
Rationale: The best response for the nurse is to ask the client to talk about specific concerns. This approach provides an opportunity for the client to express her worries openly, allowing the nurse to gather more detailed information for a comprehensive assessment and to address the client's concerns effectively.
5. A female client reports that she drank a liter of a solution to cleanse her intestines but vomited immediately after. How many ml of fluid intake should the nurse document?
- A. 1000 ml
- B. 800 ml
- C. 760 ml
- D. 500 ml
Correct answer: C
Rationale: The correct answer is 760 ml. One liter equals 1000 ml. As the client vomited immediately after drinking, she would have expelled approximately 240 ml (1 cup). Subtracting this from the initial intake of 1000 ml gives us 760 ml as the remaining fluid intake that should be documented. Choices A, B, and D are incorrect because they do not reflect the correct calculation of subtracting the amount vomited from the initial intake.
