clinical skills exam questions Questions

Question 1 of 5

The nurse is caring for a patient with a diagnosis of head trauma. The nurse notes that the patient�s urine output has increased tremendously over the past 18 hours. The nurse suspects that the patient may be developing

Correct Answer: A

Rationale: Rationale: A patient with head trauma may develop diabetes insipidus due to damage to the hypothalamus or pituitary gland, leading to decreased secretion of antidiuretic hormone (ADH). This results in excessive urine output and thirst. Other options are incorrect because: B: Diabetic ketoacidosis is associated with high blood sugar and ketones, not increased urine output. C: Hyperosmolar hyperglycemic syndrome is characterized by extreme hyperglycemia, not increased urine output. D: Syndrome of inappropriate secretion of antidiuretic hormone results in decreased urine output due to excess ADH.

Question 2 of 5

An advantage of peritoneal dialysis is that

Correct Answer: B

Rationale: The correct answer is B: a decreased risk of peritonitis exists. Peritoneal dialysis involves using the peritoneum as a membrane for fluid exchange, reducing the risk of infections like peritonitis compared to hemodialysis. Option A is incorrect as peritoneal dialysis can be done at home and is less time-consuming than hemodialysis. Option C is incorrect as biochemical disturbances are corrected more gradually with peritoneal dialysis. Option D is incorrect as there is a risk of bleeding complications with peritoneal dialysis.

Question 3 of 5

The nurse is assessing a patient with a new arteriovenous fistula, but does not hear a bruit or feel a thrill. Pulses distal to the fistula are not palpable. The nurse should

Correct Answer: C

Rationale: The correct answer is C: notify the provider immediately. Lack of bruit, thrill, and distal pulse indicates potential complications like thrombosis or occlusion in the arteriovenous fistula. Prompt provider notification is crucial for timely intervention to prevent further complications such as ischemia or access failure. Reassessing the patient in an hour (A) may delay necessary intervention. Raising the arm above the level of the patient's heart (B) does not address the underlying issue. Applying warm packs (D) could worsen the situation if there is a clot present.

Question 4 of 5

In determining the glomerular filtration rate (GFR) or creatinine clearance, a 24-hour urine is obtained. If a reliable 24-hour urine collection is not possible,

Correct Answer: D

Rationale: The correct answer is D because if a reliable 24-hour urine collection is not possible, a standardized formula can be used to estimate the GFR. This is typically done using the patient's serum creatinine level, age, sex, and race. It is a validated method when direct measurement is not feasible. A: Incorrect. It is still possible to estimate GFR using formulas when 24-hour urine collection is not possible. B: Incorrect. BUN alone is not sufficient to accurately determine renal function. C: Incorrect. BUN/Creatinine ratio is not a direct measure of GFR and may be influenced by other factors.

Question 5 of 5

Conditions that produce acute kidney injury by directly acting on functioning kidney tissue are classified as intrarenal. The most common intrarenal condition is

Correct Answer: C

Rationale: Rationale: Acute tubular necrosis (ATN) is the most common intrarenal condition causing acute kidney injury. ATN is characterized by damage to the renal tubules due to ischemia or nephrotoxic substances. Prolonged ischemia (choice A) and exposure to nephrotoxic substances (choice B) can lead to ATN. Hypotension for several hours (choice D) can result in ischemic injury, which may lead to ATN but is not the direct cause. Therefore, choice C is correct as it directly relates to the primary intrarenal condition of ATN.
