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

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 3 of 9

The patient is complaining of severe flank pain when he tries to urinate. His urinalysis shows sediment and crystals along with a few bacteria. Using this information along with the clinical picture, the nurse realizes that the patient’s condition is

Correct Answer: C

Rationale: The correct answer is C: intrarenal. The presence of sediment, crystals, and bacteria in the urinalysis indicates an issue within the kidneys themselves. The flank pain suggests renal involvement. Prerenal would involve issues before the kidneys, such as inadequate blood flow. Postrenal would involve issues after the kidneys, such as urinary tract obstruction. Not renal related is incorrect as the symptoms and urinalysis findings clearly point to a renal issue.

Question 4 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 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

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 7 of 9

The nurse has been assigned the following patients. Which patients require assessment of blood glucose control as a nursing priority? (Select all that apply.)

Correct Answer: C

Rationale: The correct answer is C because the patient with acute pancreatitis receiving TPN is at risk for hyperglycemia due to the high glucose content in TPN. Monitoring blood glucose levels is crucial to prevent complications. Explanation for why other choices are incorrect: A: The 18-year-old male post-surgery for a fractured femur does not have a direct correlation to blood glucose control assessment. B: The 29-year-old female undergoing evaluation for pheochromocytoma is not directly related to blood glucose control assessment. D: The 62-year-old morbidly obese female post-hysterectomy for ovarian cancer does not specifically require immediate blood glucose control assessment.

Question 8 of 9

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 9 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.
