ATI Med Surg Exam 10 Questions
Extract:
Question 1 of 5
Maria, an elementary student, was rushed to the hospital due to vomiting and a decreased level of consciousness. The patient displays slow and deep (Kussmaul breathing), and he is lethargic and irritable in response to stimulation. He appears to be dehydrated-his eyes are sunken and mucous membranes are dry-and he has a two-week history of polydipsia, polyuria, and weight loss. Measurement of arterial blood gas shows pH 7.0, PaO2 90 mm Hg, PaCO2 23 mm Hg, and HCO3 12 mmol/L; other results are Na+ 126 mmol/L, K+ 5 mmol/L, and Cl-95 mmol/L. What is your assessment?
Correct Answer: B
Rationale: Metabolic acidosis is indicated by a low pH and a decreased bicarbonate (HCO3) level. The body attempts to compensate by hyperventilating, evidenced by Kussmaul breathing, to decrease PaCO2. This compensation is partial because the pH is still significantly lower than normal.
Question 2 of 5
A nurse in a public clinic is researching health data on culturally diverse populations in the community. Which of the following population groups should the nurse anticipate having end-stage renal disease due to diabetes mellitus?
Correct Answer: A
Rationale: Black Americans have a higher prevalence of diabetes mellitus compared to other racial/ethnic groups in the United States, and diabetes is a leading cause of end-stage renal disease.
Question 3 of 5
A nurse is assessing a client who had a craniotomy and has developed syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following manifestations should the nurse anticipate?
Correct Answer: B
Rationale: SIADH causes the kidneys to retain water, leading to decreased urine output (oliguria) and concentrated urine due to excessive secretion of antidiuretic hormone (ADH).
Question 4 of 5
A nurse is teaching a client who has acute kidney disease about fluid restrictions. Which of the following statements by the client should the nurse identify as understanding of the teaching?
Correct Answer: C
Rationale: Not adding fluid-rich foods like ice cream to the total fluid intake demonstrates an understanding of fluid restriction and adherence to the prescribed limit.
Question 5 of 5
A nurse is reviewing the arterial blood gas values of a client who has chronic kidney disease. Which of the following sets of values should the nurse expect?
Correct Answer: C
Rationale: In patients with chronic kidney disease (CK
D), the kidneys are less able to excrete acid, leading to metabolic acidosis. The expected arterial blood gas values would show a lower pH indicating acidemia, a decreased bicarbonate (HCO3-) level, and a normal or low partial pressure of carbon dioxide (PaCO2) as the lungs try to compensate by blowing off CO2.
