clinical skills questions Questions
Question 1 of 9
Identify which substances in the glomerular filtrate would indicate a problem with renal function. (Select all that apply.)
Correct Answer: A
Rationale: The presence of protein in the glomerular filtrate indicates a problem with renal function as healthy kidneys should not allow large molecules like proteins to pass through the filtration barrier. This could be a sign of kidney damage or dysfunction. Sodium, creatinine, and red blood cells are normally present in the filtrate and are not specific indicators of renal function issues. Sodium is actively reabsorbed in the renal tubules, creatinine is a waste product filtered by the kidneys, and a small number of red blood cells may pass through the filtration barrier under normal circumstances.
Question 2 of 9
The removal of plasma water and some low–molecular weight particles by using a pressure or osmotic gradient is known as
Correct Answer: D
Rationale: The correct answer is D: ultrafiltration. Ultrafiltration involves the removal of plasma water and low-molecular weight particles using a pressure or osmotic gradient. This process allows small molecules to pass through a semipermeable membrane while retaining larger molecules. Dialysis (A) involves the removal of waste products and excess fluids from the blood, while diffusion (B) is the movement of molecules from an area of high concentration to low concentration. Clearance (C) refers to the rate at which a substance is removed from the blood by a specific organ or process. Ultrafiltration specifically targets the removal of plasma water and low-molecular weight particles through a pressure or osmotic gradient, making it the correct choice in this context.
Question 3 of 9
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 4 of 9
The nurse is caring for a patient who has a temporary percutaneous dialysis catheter in place. In caring for this patient, the nurse should
Correct Answer: C
Rationale: The correct answer is C because assessing the catheter site for redness and/or swelling is essential in monitoring for signs of infection or complications. Redness and swelling can indicate infection, which requires prompt intervention. A: Applying a sterile gauze dressing is not necessary for a temporary percutaneous dialysis catheter unless specified by the healthcare provider. B: Transparent dressings are typically left in place for several days unless there is a specific reason to change them more frequently. D: Using the catheter for drawing blood samples is not recommended as it can increase the risk of infection and may interfere with the dialysis process.
Question 5 of 9
Identify which substances in the glomerular filtrate would indicate a problem with renal function. (Select all that apply.)
Correct Answer: A
Rationale: The presence of protein in the glomerular filtrate indicates a problem with renal function as healthy kidneys should not allow large molecules like proteins to pass through the filtration barrier. This could be a sign of kidney damage or dysfunction. Sodium, creatinine, and red blood cells are normally present in the filtrate and are not specific indicators of renal function issues. Sodium is actively reabsorbed in the renal tubules, creatinine is a waste product filtered by the kidneys, and a small number of red blood cells may pass through the filtration barrier under normal circumstances.
Question 6 of 9
The nurse is assigned to care for a patient who presented to the emergency department with diabetic ketoacidosis. A continuous insulin intravenous infusion is started, and hourly bedside glucose monitoring is ordered. The targeted blood glucose value after the first hour of therapy is
Correct Answer: C
Rationale: The correct answer is C: a decrease of 35 to 90 mg/dL compared with admitting values. In diabetic ketoacidosis, there is severe hyperglycemia which needs to be corrected gradually to prevent complications like cerebral edema. A rapid decrease in glucose levels can lead to osmotic shifts and neurological issues. The targeted decrease of 35 to 90 mg/dL is considered safe and effective in managing hyperglycemia in these patients. This range ensures a controlled reduction in blood glucose levels without causing harm. Choice A (70 to 120 mg/dL) is too broad and may lead to overly aggressive treatment. Choice B (a decrease of 25 to 50 mg/dL) is too conservative and may not adequately address the high glucose levels seen in diabetic ketoacidosis. Choice D (less than 200 mg/dL) does not provide a specific target range for glucose reduction, which is essential in managing diabetic ketoacidosis effectively.
Question 7 of 9
A patient with long-standing type 1 diabetes presents to the emergency department with a loss of consciousness and seizure activity. The patient has a history of renal insufficiency, gastroparesis, and peripheral diabetic neuropathy. Emergency personnel reported a blood glucose of 32 mg/dL on scene. When providing discharge teaching for this patient and family, the nurse instructs on the need to do which of the following? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B: Administer 15 grams of carbohydrate orally for severe episodes of hypoglycemia. In this scenario, the patient is experiencing severe hypoglycemia (blood glucose of 32 mg/dL) leading to loss of consciousness and seizure activity. Administering 15 grams of carbohydrate orally is crucial to rapidly raise the blood glucose levels and address the hypoglycemia. This immediate intervention can help reverse the symptoms and prevent further complications. The incorrect choices: A: Administering glucagon intramuscularly is typically reserved for severe hypoglycemia when the patient cannot take anything by mouth. In this case, oral intake is preferred for faster absorption. C: Discontinuing the insulin pump is not necessary in this situation since the primary concern is treating the acute hypoglycemia. Removing the infusion set can lead to hyperglycemia if not managed properly. D: Increasing home blood glucose monitoring and reporting patterns of hyp
Question 8 of 9
The critical care nurse is responsible for monitoring the patient receiving continuous renal replacement therapy (CRRT). In doing so, the nurse should
Correct Answer: B
Rationale: Correct Answer: B Rationale: 1. Hemofilter clotting can affect CRRT efficiency. 2. Assessing every 6 hours allows early detection and intervention. 3. Clotting can lead to treatment interruptions or complications. 4. Regular assessment ensures optimal therapy delivery. Other Choices: A: Assessing tubing warmth is not a reliable indicator of CRRT function or complications. C: Covering dialysis lines to protect from light is not a standard practice in CRRT monitoring. D: Using clean technique is not sufficient for vascular access dressing changes; aseptic technique is required for infection prevention.
Question 9 of 9
The nurse is providing insulin education for an elderly patient with long-standing diabetes. A prescription has been written for the patient to take 20 units of insulin glargine at 10 PM nightly. The nurse should instruct the patient that the peak of the insulin action for this agent is
Correct Answer: D
Rationale: The correct answer is D: peakless. Insulin glargine is a long-acting insulin with a smooth, consistent release of insulin over 24 hours, providing a steady level of insulin without a pronounced peak. This characteristic helps in maintaining stable blood glucose levels. Options A, B, and C are incorrect as they refer to peak values that do not apply to insulin glargine.
