clinical skills questions Questions
Question 1 of 5
A normal glomerular filtration rate is
Correct Answer: B
Rationale: The correct answer is B (80 to 125 mL/min) because this range represents the normal glomerular filtration rate (GFR) for a healthy adult. GFR indicates the rate at which blood is filtered by the kidneys, with 125 mL/min being the average value. Values below 80 mL/min (Choice A) suggest impaired kidney function, while values above 189 mL/min (Choice D) may indicate hyperfiltration or underlying conditions. Choice C (125 to 180 mL/min) falls within the normal range, but the typical average is around 125 mL/min. Thus, choice B is the correct answer as it reflects the standard GFR range for adults.
Question 2 of 5
The nurse is caring for a patient who has undergone major abdominal surgery. The nurse notices that the patient’s urine output has been less than 20 mL/hour for the past 2 hours. The patient’s blood pressure is 100/60 mm Hg, and the pulse is 110 beats/min. Previously, the pulse was 90 beats/min with a blood pressure of 120/80 mm Hg. The nurse should
Correct Answer: A
Rationale: Rationale: 1. Urine output < 20 mL/hour indicates potential hypoperfusion. 2. Decreased urine output with hypotension and tachycardia suggests inadequate fluid resuscitation. 3. Administering a normal saline bolus can help improve perfusion and stabilize blood pressure. 4. Contacting the provider promptly for orders is crucial in managing this acute situation. Summary of Incorrect Choices: B. Delaying reporting to the provider risks worsening the patient's condition. C. Continuing to evaluate urine output without intervention can lead to further deterioration. D. Ignoring the urine output due to potential postrenal causes overlooks the urgent need for fluid resuscitation.
Question 3 of 5
The patient undergoes a cardiac catheterization that requires the use of contrast dyes during the procedure. To detect signs of contrast-induced kidney injury, the nurse should
Correct Answer: B
Rationale: Correct Answer: B Rationale: 1. Contrast dyes can cause kidney injury due to their nephrotoxic effects. 2. Serum creatinine levels are a reliable indicator of kidney function. 3. Evaluating serum creatinine for up to 72 hours after the procedure allows detection of any contrast-induced kidney injury. 4. Monitoring serum creatinine helps in early identification and intervention for renal complications. Summary: A: Incorrect. Urine output alone is not a definitive indicator of kidney injury. C: Incorrect. Renal ultrasound is not typically used for detecting contrast-induced kidney injury. D: Incorrect. Postvoid residual volume is not specific for contrast-induced kidney injury.
Question 4 of 5
The patient has elevated blood urea nitrogen (BUN) and serum creatinine levels with a normal BUN/creatinine ratio. These levels most likely indicate
Correct Answer: B
Rationale: The elevated BUN and serum creatinine levels with a normal BUN/creatinine ratio suggest kidney dysfunction. This pattern is commonly seen in acute kidney injury, like acute tubular necrosis (ATN), where the kidneys are unable to properly filter waste products. Other choices (A) increased nitrogen intake and (C) hypovolemia would not cause the specific pattern of elevated BUN and creatinine levels with a normal ratio. (D) Fluid resuscitation would actually aim to correct hypovolemia and would not directly affect the BUN and creatinine levels.
Question 5 of 5
In calculating the glomerular filtration rate (GFR) results for women, the creatinine clearance is usually:
Correct Answer: A
Rationale: The correct answer is A: the same as for men. GFR is calculated based on factors like age, weight, and serum creatinine levels, which are not directly influenced by gender. Therefore, the creatinine clearance for women is the same as for men. Choices B, C, and D are incorrect because there is no inherent biological difference between men and women that would cause a difference in creatinine clearance for GFR calculation.
