The patient is admitted to the unit with the diagnosis of rhabdomyolysis. The patient is started on intravenous (IV) fluids and IV mannitol. What action by the nurse is best?
- A. Assess the patient’s hearing.
- B. Assess the patient’s lungs.
- C. Decrease IV fluids once the diuretic has been administered.
- D. Give extra doses before giving radiological contrast agents.
Correct Answer: B
Rationale: The correct answer is B: Assess the patient's lungs. In rhabdomyolysis, muscle breakdown releases myoglobin which can cause kidney damage. Mannitol is given to prevent kidney damage by promoting diuresis. However, mannitol can also cause fluid overload and pulmonary edema. Therefore, assessing the patient's lungs is crucial to monitor for signs of fluid overload and prevent complications.
A: Assessing the patient's hearing is not directly related to the management of rhabdomyolysis and mannitol administration.
C: Decreasing IV fluids after administering a diuretic like mannitol can lead to inadequate fluid resuscitation and worsening kidney injury.
D: Giving extra doses before radiological contrast agents is not necessary in the context of rhabdomyolysis and mannitol administration.

Noninvasive diagnostic procedures used to determine kidney function include which of the following? (Select all that apply.)
- A. Kidney, ureter, bladder (KUB) x-ray
- B. Renal ultrasound
- C. Magnetic resonance imaging (MRI)
- D. Intravenous pyelography (IVP)
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
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
- A. diabetes insipidus.
- B. diabetic ketoacidosis.
- C. hyperosmolar hyperglycemic syndrome.
- D. syndrome of inappropriate secretion of antidiuretic hormone.
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.
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?
- A. Calcium
- B. Chloride
- C. Potassium
- D. Sodium
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.
Which of the following statements is true about the medical management of diabetic ketoacidosis?
- A. Serum lactate levels are used to guide insulin administration.
- B. Sodium bicarbonate is a first-line medication for treatment.
- C. The degree of acidosis is assessed through continuous pulse oximetry.
- D. Volume replacement and insulin infusion often correct the acidosis.
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.
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
- A. prepare to assist with a routine dialysis catheter change.
- B. evaluate the patient for signs and symptoms of infection.
- C. teach the patient that the catheter is designed for long-term use.
- D. use one of the three lumens for fluid administration.
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.
