Question 1 of 5

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 2 of 5

The patient is diagnosed with acute kidney injury and has been getting dialysis 3 days per week. The patient complains of general malaise and is tachypneic. An arterial blood gas shows that the patient�s pH is 19, with a PCO of 30 mm Hg and a bicarbonate level of 13 mEq/L. The nurse prepares to

Correct Answer: B

Rationale: The correct answer is B: prepare for intubation and mechanical ventilation. The patient's arterial blood gas results indicate metabolic acidosis (low pH, low bicarbonate) with respiratory compensation (low PCO). In this scenario, the patient is likely experiencing respiratory fatigue due to tachypnea from metabolic acidosis. Intubation and mechanical ventilation are needed to support the patient's respiratory effort and correct the acid-base imbalance. Administering morphine (choice A) can further depress the respiratory drive. Administering intravenous sodium bicarbonate (choice C) can temporarily correct the pH but does not address the underlying respiratory distress. Canceling dialysis (choice D) is not indicated as it does not address the acute respiratory compromise.

Question 3 of 5

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 4 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.

Question 5 of 5

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.
