Nursing Elites

1. Which of the following is a common cause of acute kidney injury?

• A. Hypertension
• B. Dehydration
• C. Infection
• D. Hypotension

Correct answer: C

Rationale: Infection is a common cause of acute kidney injury because when the body fights an infection, it activates the immune response, leading to inflammation. This inflammatory response can affect the kidneys and impair their function. While hypertension (choice A) is a risk factor for chronic kidney disease, it is not a direct cause of acute kidney injury. Dehydration (choice B) can lead to prerenal acute kidney injury due to decreased blood flow to the kidneys, but infection is a more common cause of acute kidney injury. Hypotension (choice D) can contribute to prerenal acute kidney injury, but it is not a direct cause like infection.

2. A client who underwent surgery and experienced significant blood loss is being cared for by a nurse. Which findings by the nurse should prompt immediate action to prevent acute kidney injury? (Select all that apply.)

• A. Urine output of 100 mL in 4 hours
• B. Large amount of sediment in the urine
• C. A & B
• D. Amber, odorless urine

Correct answer: C

Rationale: The nurse must monitor for signs of acute kidney injury in a postoperative client who had major blood loss. Low urine output, presence of sediment in the urine, and low blood pressure should raise concerns and be reported to the healthcare provider promptly. Postoperatively, assessing urine characteristics is crucial. Sediment, hematuria, and urine output less than 0.5 mL/kg/hour for 3 to 4 hours should be reported. While a urine output of 100 mL in 4 hours is low, it should be compared to the recommended 0.5 mL/kg/hour over a longer period. Perfusion to the kidneys is a priority, hence the importance of addressing low blood pressure. Amber, odorless urine is considered normal and does not indicate an immediate concern for acute kidney injury, unlike low urine output and presence of sediment.

3. The client has had a femoral-popliteal bypass surgery 6 hours ago. Which assessment provides the most accurate information about the client's postoperative status?

• A. Radial pulse.
• B. Femoral pulse.
• C. Apical pulse.
• D. Dorsalis pedis pulse.

Correct answer: D

Rationale: Assessing the dorsalis pedis pulse is crucial after a femoral-popliteal bypass surgery to determine adequate circulation distal to the surgical site. A strong dorsalis pedis pulse indicates sufficient blood flow to the foot, which is essential for monitoring postoperative status. The radial pulse (A) is not the most relevant assessment as it does not provide direct information on circulation in the lower extremities. The femoral pulse (B) may not accurately reflect circulation distal to the surgical site. The apical pulse (C) is used primarily to assess the heartbeat and cardiac function, not circulation in the lower extremities.

4. A client is brought to the emergency department by a neighbor. The client is lethargic and has a fruity odor on the breath. The client’s arterial blood gas (ABG) results are pH 7.25, PCO2 34 mm Hg, PO2 86 mm Hg, HCO3 14 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: The correct answer is 'Metabolic acidosis.' Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (HCO3 <22 mEq/L). In this case, the client's ABG results show a pH of 7.25 and an HCO3 level of 14 mEq/L, indicating metabolic acidosis. The PCO2 of 34 mm Hg is normal, ruling out respiratory acidosis or alkalosis. The PO2 of 86 mm Hg is also within the normal range and is not indicative of a respiratory problem. Therefore, the client is experiencing metabolic acidosis based on the ABG results provided.

5. Oxygen via nasal cannula has been prescribed for a client with emphysema. The nurse checks the physician’s orders to ensure that the prescribed flow is not greater than:

• A. 1 L/min
• B. 3 L/min
• C. 4 L/min
• D. 6 L/min

Correct answer: B

Rationale: The correct answer is B, 3 L/min. Clients with emphysema typically receive oxygen at a flow rate of 1 to 2 L/min, with a maximum of 3 L/min. Higher flow rates can lead to oxygen toxicity in these clients, so it's crucial to adhere to the prescribed limits. Choice A (1 L/min) is too low and may not provide adequate oxygenation for the client. Choices C (4 L/min) and D (6 L/min) exceed the recommended flow rates for clients with emphysema and can increase the risk of oxygen toxicity.
