Question 1 of 9
Noninvasive diagnostic procedures used to determine kidney function include which of the following? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Kidney, ureter, bladder (KUB) x-ray. KUB x-ray is a noninvasive diagnostic procedure that provides information about the size, shape, and position of the kidneys, ureters, and bladder. It can help detect abnormalities such as kidney stones or structural issues. Rationale: 1. KUB x-ray is noninvasive, meaning it does not require any incisions or insertion of instruments into the body. 2. It is commonly used as an initial screening tool to assess kidney function. 3. Renal ultrasound (Choice B) is also noninvasive but primarily used for imaging the kidneys and not the entire urinary system. 4. MRI (Choice C) and IVP (Choice D) are more invasive procedures that involve injecting contrast agents and may not be routinely used for initial kidney function assessment. In summary, the KUB x-ray is the correct choice as it is a noninvasive procedure specifically designed to evaluate kidney
Question 2 of 9
The nurse is caring for a patient who has sustained blunt trauma to the left flank area, and is evaluating the patient’s urinalysis results. The nurse should become concerned when
Correct Answer: D
Rationale: The correct answer is D because the presence of red blood cells and albumin in the urine indicates kidney damage, as these are not normally found in urine. A: Creatinine levels should be similar in blood and urine for proper kidney function. B: Sodium and chloride are normal components of urine. C: Uric acid levels can vary in urine and serum. Therefore, D is the correct answer as it signals potential kidney injury.
Question 3 of 9
An elderly female patient has presented to the emergency department with altered mental status, hypothermia, and clinical signs of heart failure. Myxedema is suspected. Which of the following laboratory findings support this diagnosis?
Correct Answer: C
Rationale: Rationale for Correct Answer (C): Elevated T and T3/T4 levels are indicative of primary hypothyroidism, such as myxedema. In this case, the patient presents with classic symptoms of hypothyroidism, including altered mental status, hypothermia, and heart failure. Elevated T3/T4 levels confirm the diagnosis. Summary of Incorrect Choices: A: Elevated adrenocorticotropic hormone is associated with adrenal disorders, not hypothyroidism. B: Elevated cortisol levels suggest Cushing's syndrome, a condition of excess cortisol production, not hypothyroidism. D: Elevated thyroid-stimulating hormone is seen in primary hypothyroidism, but in myxedema, the issue is not with TSH but with T3/T4 levels.
Question 4 of 9
The patient has a temporary percutaneous catheter in place for treatment of acute kidney injury. The catheter has been in place for 5 days. The nurse should
Correct Answer: B
Rationale: The correct answer is B: evaluate the patient for signs and symptoms of infection. After 5 days, infection risk increases. Signs of infection include fever, redness, swelling, and tenderness at the catheter site. Monitoring for these signs is crucial to prevent complications. A: Routine dialysis catheter change is not indicated after 5 days. C: Teaching long-term use is incorrect as temporary catheters are not meant for extended use. D: Using lumens for fluid administration can increase infection risk and is not recommended.
Question 5 of 9
A patient is admitted to the critical care unit with a diagnosis of diabetic ketoacidosis. Following aggressive fluid resuscitation and intravenous (IV) insulin administration, the blood glucose begins to normalize. In addition to glucose monitoring, which of the following electrolytes requires close monitoring?
Correct Answer: C
Rationale: The correct answer is C: Potassium. During treatment of diabetic ketoacidosis, as blood glucose levels decrease, potassium levels can quickly drop due to insulin therapy driving potassium into cells. Monitoring potassium levels closely is crucial to prevent hypokalemia, which can lead to life-threatening cardiac arrhythmias. Choice A: Calcium - Calcium levels are not typically affected by diabetic ketoacidosis treatment and do not require immediate monitoring in this context. Choice B: Chloride - Chloride levels are usually not significantly impacted by diabetic ketoacidosis treatment and do not need close monitoring in this case. Choice D: Sodium - While sodium levels can be affected by dehydration in diabetic ketoacidosis, they are not as critical to monitor as potassium levels during treatment.
Question 6 of 9
Which of the following patients is at the greatest risk of developing acute kidney injury? A patient who
Correct Answer: C
Rationale: The correct answer is C because the patient was recently discharged after a prolonged course of aminoglycoside therapy, which is a known risk factor for acute kidney injury due to its nephrotoxic effects. Choice A is incorrect because although aminoglycosides can cause kidney injury, the duration of therapy is shorter in this case. Choice B is incorrect because controlled hypertension is not a significant risk factor for acute kidney injury. Choice D is incorrect because fluid overload from heart failure may lead to other complications but is not directly associated with acute kidney injury.
Question 7 of 9
Which of the following statements is true about the medical management of diabetic ketoacidosis?
Correct Answer: D
Rationale: The correct answer is D. Volume replacement and insulin infusion often correct the acidosis in diabetic ketoacidosis (DKA) because volume depletion and insulin deficiency are key factors in its pathophysiology. Volume replacement helps correct dehydration and improve tissue perfusion, while insulin infusion helps lower blood glucose levels and inhibit ketone production, ultimately correcting the acidosis. A is incorrect because serum lactate levels are not typically used to guide insulin administration in DKA. B is incorrect as sodium bicarbonate is not a first-line medication for DKA treatment as it can worsen metabolic acidosis. C is incorrect as the degree of acidosis in DKA is typically assessed through blood gas analysis, not continuous pulse oximetry.
Question 8 of 9
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 9 of 9
The patient has been admitted to the hospital with nausea and vomiting that started 5 days earlier. Blood pressure is 80/44 mm Hg and heart rate is 122 beats/min; the patient has not voided in 8 hours, and the bladder is not distended. The nurse anticipates a prescription for “stat” administration of
Correct Answer: B
Rationale: The correct answer is B: fluid replacement with 0.45% saline. The patient's symptoms suggest dehydration and hypovolemia, indicated by low blood pressure, elevated heart rate, and lack of urine output. Fluid replacement with isotonic saline would help restore intravascular volume and improve blood pressure. Blood transfusion (A) is not indicated without evidence of significant blood loss. Inotropic agents (C) are used to improve cardiac function, which is not the primary issue in this case. Antiemetics (D) may help with nausea and vomiting but do not address the underlying cause of hypovolemia.
