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 most significant clinical finding of acute adrenal crisis associated with fluid and electrolyte imbalance is
Correct Answer: C
Rationale:
Step-by-step rationale for the correct answer (C: hyperkalemia):
1. Adrenal crisis leads to adrenal insufficiency, causing decreased cortisol levels.
2. Cortisol plays a crucial role in regulating potassium levels.
3. With decreased cortisol, potassium levels can rise, leading to hyperkalemia.
4. Hyperkalemia can result in life-threatening cardiac arrhythmias.
Summary:
A: Fluid volume excess is not typical in adrenal crisis.
B: Hyperglycemia can be present but is not the most significant finding.
D: Hypernatremia is not a typical feature of adrenal crisis.
Question 3 of 5
What is a minimally acceptable urine output for a patient weighing 75 kg?
Correct Answer: C
Rationale: The correct answer is C (80 mL/hour) as it is considered a minimally acceptable urine output for a patient weighing 75 kg. Adequate urine output is crucial for kidney function and fluid balance. The general rule is to maintain a urine output of at least 0.5 mL/kg/hour, which in this case would be 37.5 mL/hour for a 75 kg patient. Option C (80 mL/hour) exceeds this minimum requirement, ensuring proper kidney perfusion and waste elimination. Options A (Less than 30 mL/hour) and D (150 mL/hour) are incorrect as they fall below or exceed the recommended urine output range, potentially indicating renal impairment or fluid overload, respectively. Option B (37 mL/hour) is close to the minimum requirement but does not provide a sufficient margin for variations in fluid status or kidney function.
Question 4 of 5
What psychosocial factors may potentially contribute to the development of diabetic ketoacidosis? (Select all that apply.)
Correct Answer: A
Rationale: Rationale for correct answer A: Altered sleep/rest patterns can disrupt insulin regulation, leading to glucose imbalance and predisposing to diabetic ketoacidosis. Lack of sleep affects hormones that regulate blood sugar levels, increasing the risk of DKA.
Summary of why other choices are incorrect:
B: Eating disorder can affect blood sugar control but is not a direct cause of DKA.
C: Exposure to influenza may trigger stress on the body but is not a psychosocial factor contributing to DKA.
D: High levels of stress can impact blood sugar levels but are not specific psychosocial factors leading to DKA.
Question 5 of 5
The nurse is caring for an elderly patient who was admitted with renal insufficiency. An expected laboratory finding for this patient may be
Correct Answer: C
Rationale:
Correct
Answer: C - Increased ability to excrete drugs.
Rationale:
1. Renal insufficiency impairs kidney function, leading to decreased excretion of drugs.
2. In elderly patients with renal insufficiency, there may be compensatory mechanisms to enhance drug excretion.
3. This increased ability to excrete drugs helps prevent drug accumulation and potential toxicity.
Summary:
A: Increased GFR is not expected in renal insufficiency; it typically decreases.
B: Serum creatinine level would likely be elevated in renal insufficiency, not normal.
D: Hypokalemia is not a typical lab finding in renal insufficiency; hyperkalemia is more common.
