Question 1 of 9

The patient is admitted with acute kidney injury from a postrenal cause. Acceptable treatments for that diagnosis include: (Select all that apply.)

Correct Answer: A

Rationale: The correct answer is A. Bladder catheterization helps relieve urinary obstruction, a common postrenal cause of acute kidney injury. It allows urine to drain freely from the bladder. - B: Increasing fluid volume intake may worsen the condition by increasing the pressure on the obstructed kidneys. - C: Ureteral stenting is used for intrarenal causes, not postrenal causes. - D: Placement of nephrostomy tubes bypasses the obstruction but is usually reserved for more severe cases.

Question 2 of 9

The patient is in need of immediate hemodialysis, but has no vascular access. The nurse prepares the patient for insertion of

Correct Answer: A

Rationale: The correct answer is A: a percutaneous catheter at the bedside. In this urgent situation, a percutaneous catheter can be quickly inserted at the bedside to provide immediate vascular access for hemodialysis. This option allows for rapid initiation of treatment without the need for surgical placement or waiting for a more permanent access like an arteriovenous fistula or graft. Incorrect Choices: B: A percutaneous tunneled catheter may require more time for insertion due to tunneling and may not be suitable for immediate use. C: An arteriovenous fistula is a more permanent access created surgically and requires time to mature before being used for hemodialysis. D: An arteriovenous graft is also a surgical option that requires time to heal and mature before being used for hemodialysis.

Question 3 of 9

The patient is on intake and output (I&O), as well as daily weights. The nurse notes that output is considerably less than intake over the last shift, and daily weight is 1 kg more than yesterday. The nurse should

Correct Answer: C

Rationale: The correct answer is C: assess the patient's lungs. The discrepancy between intake, output, and weight gain indicates a potential fluid imbalance. By assessing the patient's lungs, the nurse can identify signs of fluid overload, such as crackles or difficulty breathing, which could explain the weight gain and imbalance. This step is crucial in determining the underlying cause and guiding further interventions. Drawing a trough level (A) or inserting an indwelling catheter (D) are not necessary at this point and may not address the immediate issue. Placing the patient on fluid restriction (B) should only be considered after a thorough assessment to determine the cause of the imbalance.

Question 4 of 9

A normal urine output is considered to be

Correct Answer: D

Rationale: The correct answer is D: 1 to 2 L/day. Normal urine output typically ranges from 1 to 2 liters per day, which is considered adequate for maintaining proper hydration and eliminating waste products. A: 80 to 125 mL/min is too low for daily output. B: 180 L/day is excessively high and unrealistic. C: 80 mL/min is also too low for daily urine output. Therefore, D is the most appropriate choice based on standard guidelines for urine excretion.

Question 5 of 9

A patient presents to the emergency department with suspected thyroid storm. The nurse should be alert to which of the following cardiac rhythms while providing care to this patient?

Correct Answer: A

Rationale: The correct answer is A: Atrial fibrillation. In thyroid storm, excess thyroid hormone levels can lead to increased sympathetic activity, causing tachycardia and arrhythmias like atrial fibrillation. Atrial fibrillation is common in thyroid storm due to the hypermetabolic state and increased risk of atrial arrhythmias. Other choices are incorrect: B (Idioventricular rhythm) is not typically associated with thyroid storm, C (Junctional rhythm) is less likely since atrial arrhythmias are more common, and D (Sinus bradycardia) is unlikely due to the hypermetabolic state causing tachycardia.

Question 6 of 9

The critical care nurse knows that in critically ill patients, renal dysfunction

Correct Answer: B

Rationale: The correct answer is B because renal dysfunction is a common issue in critically ill patients due to factors like sepsis or hypoperfusion. This affects nearly two thirds of patients, leading to potential complications. Choice A is incorrect as renal dysfunction is common, not rare. Choice C is incorrect as mortality rates can still be high even with renal replacement therapy. Choice D is incorrect as renal dysfunction can significantly impact morbidity, mortality, and quality of life in critically ill patients.

Question 7 of 9

Acute kidney injury from postrenal etiology is caused by

Correct Answer: A

Rationale: The correct answer is A because acute kidney injury from postrenal etiology is caused by obstruction of the flow of urine, leading to back pressure and damage to the kidneys. Choices B and C relate to prerenal causes, affecting renal perfusion and volume status. Choice D refers to intrinsic renal causes, directly affecting kidney tissue function, not postrenal obstruction. Therefore, A is correct due to the nature of postrenal etiology.

Question 8 of 9

Continuous venovenous hemofiltration is used to

Correct Answer: A

Rationale: The correct answer is A because continuous venovenous hemofiltration primarily removes fluids and solutes through convection. Convection involves the movement of solutes across a semi-permeable membrane by the force of the fluid flow. This process helps to achieve fluid balance and manage electrolyte levels in patients with renal failure. Choice B is incorrect because hemofiltration does not specifically target plasma water; it aims to remove both fluids and solutes. Choice C is incorrect as hemofiltration does not involve adding dialysate; it relies on the patient's blood passing through a filter to remove waste products. Choice D is incorrect because while hemofiltration may involve aspects of ultrafiltration and dialysis, the primary mechanism is convection for removing fluids and solutes.

Question 9 of 9

A patient with a history of type 1 diabetes and an eating disorder is found unconscious. In the emergency department, the following lab values are obtained: Glucose: 648 mg/dL pH: 88 P CO : 20 mm Hg a 2 P O : 95 mm Hg a 2 HCO ¯: undetectable Anion gap: >31 Na+: 127 mEq/L K+: 5 mEq/L Creatinine: 8 mg/dL After the patient’s airway and ventilation have been established, the next priority for this patient is:

Correct Answer: A

Rationale: The correct answer is A: administration of a 1-L normal saline fluid bolus. In this scenario, the patient is likely experiencing diabetic ketoacidosis (DKA) due to the extremely high glucose levels, low bicarbonate, and anion gap metabolic acidosis. The priority is to correct the dehydration and electrolyte imbalances through fluid resuscitation with normal saline to improve perfusion and reverse the metabolic derangements. Options B, C, and D do not address the immediate need for volume resuscitation and correction of dehydration. Administering insulin or potassium without first addressing the fluid deficit could lead to further complications. Sodium bicarbonate is not recommended in DKA as it can worsen acidosis and has not been shown to improve outcomes.
