1. A healthcare professional is verifying nasogastric tube placement by the pH of aspirated gastric fluid. Which of the following pH values provides a good indication of correct tube placement?

• A. 2
• B. 5
• C. 7
• D. 9

Correct answer: A

Rationale: The correct answer is A: '2'. Gastric contents with a pH between 0 and 4 provide a good indication of appropriate tube placement. A pH of 2 is within this range, indicating that the tube is correctly placed in the stomach. Choices B, C, and D are incorrect because a pH of 5, 7, or 9 does not fall within the expected acidic pH range of gastric fluid.

2. A nurse is assessing a client who has diabetic ketoacidosis (DKA). Which of the following laboratory findings should the nurse expect?

• A. Blood glucose 120 mg/dL
• B. pH 7.32
• C. HCO3 25 mEq/L
• D. PaCO2 48 mm Hg

Correct answer: B

Rationale: The correct answer is B. A pH of 7.32 indicates metabolic acidosis, which is a hallmark of diabetic ketoacidosis (DKA). In DKA, blood glucose levels are typically elevated, bicarbonate levels are often low, and there is a compensatory respiratory response leading to a decrease in PaCO2. Option A is incorrect because a blood glucose level of 120 mg/dL is within the normal range and not indicative of DKA. Option C is incorrect because an HCO3 level of 25 mEq/L is not typically seen in DKA where bicarbonate levels are usually lower. Option D is incorrect because a PaCO2 of 48 mm Hg would not be expected in DKA; it would typically be lower due to compensatory respiratory alkalosis.

3. A nurse is assessing a client with pneumonia. Which of the following findings should the nurse expect?

• A. Bradycardia
• B. Increased respiratory rate
• C. Decreased temperature
• D. Elevated blood pressure

Correct answer: B

Rationale: The correct answer is B: Increased respiratory rate. In pneumonia, the body tries to compensate for the reduced ability to oxygenate the blood by increasing the respiratory rate. This helps to improve oxygen exchange. Bradycardia (Choice A) is not typically associated with pneumonia, as an increased heart rate is more common due to the stress on the body. Decreased temperature (Choice C) is not a typical finding in pneumonia, as infections usually cause a fever. Elevated blood pressure (Choice D) is not a common finding in pneumonia unless there are complications such as sepsis.

4. A nurse is providing education on the use of aspirin. Which of the following should be included?

• A. It can increase the risk of bleeding
• B. It is safe to give to children
• C. It should be taken on an empty stomach
• D. It has no side effects

Correct answer: A

Rationale: The correct answer is A: 'It can increase the risk of bleeding.' Aspirin is known to have antiplatelet effects and can increase the risk of bleeding, especially if taken in high doses or for prolonged periods. Choice B is incorrect because aspirin is not safe for children due to the risk of Reye's syndrome. Choice C is incorrect because aspirin should be taken with food to minimize gastrointestinal side effects. Choice D is incorrect because aspirin, like any medication, can have side effects, such as gastrointestinal bleeding, ulcers, or allergic reactions.

5. A nurse is preparing to administer a dose of warfarin. Which of the following should the nurse do?

• A. Check INR levels
• B. Administer it with food
• C. Monitor blood glucose
• D. Assess liver function

Correct answer: A

Rationale: The correct answer is to check INR levels. Before administering warfarin, it is crucial to check the INR levels to ensure they are within the therapeutic range. This helps to prevent complications such as bleeding or clotting. Choice B, administering it with food, is incorrect as warfarin should typically be taken on an empty stomach. Choice C, monitoring blood glucose, is unrelated to the administration of warfarin. Choice D, assessing liver function, is important but not the immediate action required before administering warfarin.
