1. Which lab result would be most indicative of renal failure?

• A. Elevated creatinine levels.
• B. Low potassium levels.
• C. Low calcium levels.
• D. High sodium levels.

Correct answer: A

Rationale: The correct answer is A: Elevated creatinine levels. Creatinine is a waste product that is normally filtered by the kidneys. Elevated creatinine levels indicate impaired kidney function, which is commonly seen in renal failure. Choice B, low potassium levels, is not typically associated with renal failure. In fact, renal failure is more likely to cause high potassium levels due to the kidneys' inability to excrete potassium effectively. Choice C, low calcium levels, are not directly indicative of renal failure. Renal failure can lead to disturbances in calcium levels, but low calcium levels alone are not a specific marker for renal failure. Choice D, high sodium levels, are also not typically associated with renal failure. In renal failure, there may be disturbances in sodium levels, but high sodium levels alone are not a direct indicator of renal failure.

2. In a patient with liver cirrhosis, which of the following lab results would be expected?

• A. Increased bilirubin levels.
• B. Decreased albumin levels.
• C. Increased liver enzymes.
• D. Decreased platelet count.

Correct answer: A

Rationale: In a patient with liver cirrhosis, increased bilirubin levels would be expected. Liver cirrhosis leads to impaired liver function, causing a decrease in the liver's ability to process bilirubin, leading to its accumulation in the blood. This results in elevated bilirubin levels. Decreased albumin levels (choice B) may occur in liver cirrhosis due to impaired liver synthesis of proteins, but it is not as specific as increased bilirubin levels. Increased liver enzymes (choice C) can be seen in liver damage but are not as characteristic as elevated bilirubin levels. Decreased platelet count (choice D) can occur in liver cirrhosis due to hypersplenism, but it is not as specific as increased bilirubin levels in this context.

3. The home health nurse provides teaching about insulin self-injection to a client who was recently diagnosed with diabetes mellitus. When the client begins to perform a return demonstration of an insulin injection into the abdomen, which instruction should the nurse provide?

• A. Select a different injection site
• B. Continue with the insulin injection
• C. Keep the skin flat rather than bunched
• D. Lie down flat for better skin exposure

Correct answer: B

Rationale: Choosing to continue with the insulin injection is the correct instruction in this scenario because it allows the client to demonstrate proper technique and reinforces their learning. Selecting a different injection site (choice A) is not necessary if the client is injecting into the abdomen as it is a suitable site. Keeping the skin flat rather than bunched (choice C) is a good practice but is not the priority in this situation where the client is demonstrating the injection technique. Lying down flat for better skin exposure (choice D) is not required and may not be practical for the client during routine self-injections.

4. A client is experiencing diarrhea. For which acid-base disorder should the nurse assess the client?

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

Correct answer: A

Rationale: When a client experiences diarrhea, the loss of bicarbonate-rich fluids from the body leads to a decrease in the bicarbonate levels in the blood, resulting in metabolic acidosis. Metabolic alkalosis (choice B) is characterized by an increase in bicarbonate levels, which is not typically associated with diarrhea. Respiratory acidosis (choice C) is caused by retention of carbon dioxide, while respiratory alkalosis (choice D) results from excessive exhalation of carbon dioxide, neither of which are directly related to diarrhea. Therefore, the correct answer is metabolic acidosis (choice A) in the context of diarrhea.

5. The patient weighs 75 kg and is receiving IV fluids at a rate of 50 mL/hour, having consumed 100 mL orally in the past 24 hours. What action will the nurse take?

• A. Contact the provider to ask about increasing the IV rate to 90 mL/hour.
• B. Discuss with the provider the need to increase the IV rate to 150 mL/hour.
• C. Encourage the patient to drink more water so the IV can be discontinued.
• D. Instruct the patient to drink 250 mL of water every 8 hours.

Correct answer: A

Rationale: The recommended daily fluid intake for adults is 30 to 40 mL/kg/day. For a patient weighing 75 kg, the minimum intake should be 2250 mL/day. The patient is currently receiving 1200 mL IV and 100 mL orally, totaling 1300 mL. Increasing the IV rate to 90 mL/hour would provide a total of 2160 mL, which could meet the patient's needs if oral intake continues. Option B suggests increasing the IV rate to 150 mL/hour, resulting in an excessive fluid intake of 3600 mL/day, surpassing the recommended amount. Option C, encouraging increased fluid intake, is not recommended as the patient is already struggling with fluid intake. Option D, instructing the patient to drink 250 mL of water every 8 hours, would still fall short of the required fluid intake of 2250 mL/day.
