Nursing Elites

1. A client is preparing advance directives. Which of the following statements by the client indicates an understanding of advance directives?

• A. I cannot change my instructions once they are made
• B. My doctor will need to approve my advance directives
• C. I need an attorney to witness my signature on the advance directives
• D. I have the right to refuse treatment

Correct answer: D

Rationale: The correct answer is D: 'I have the right to refuse treatment.' This statement indicates an understanding of advance directives because advance directives allow individuals to express their treatment preferences, including the right to refuse treatment if they choose to do so. Choice A is incorrect because individuals can update or change their advance directives as needed. Choice B is incorrect because advance directives are based on the individual's preferences, not the doctor's approval. Choice C is incorrect as witnessing an advance directive typically requires a witness who is not an attorney, depending on the state's specific requirements.

2. A nurse is caring for a client who has an indwelling urinary catheter. What should the nurse identify as a catheter occlusion?

• A. Pain during urination
• B. Bladder distention
• C. Cloudy urine
• D. Blood in the catheter tube

Correct answer: B

Rationale: The correct answer is B: Bladder distention. Bladder distention indicates that the bladder is full and there is impaired elimination, which could be caused by catheter occlusion. Pain during urination (choice A) is not typically associated with catheter occlusion but may indicate a urinary tract infection. Cloudy urine (choice C) can be a sign of infection but is not specific to catheter occlusion. Blood in the catheter tube (choice D) may indicate trauma during catheter insertion but is not a typical finding in catheter occlusion.

3. A client has been prescribed enoxaparin. Which of the following instructions should the nurse provide regarding self-administration?

• A. Pinch the skin and inject at a 45-degree angle
• B. Massage the injection site after administering
• C. Administer at a 90-degree angle
• D. Avoid rotating injection sites

Correct answer: A

Rationale: The correct answer is to pinch the skin and inject at a 45-degree angle when administering enoxaparin. This technique helps ensure proper administration of the medication. Massaging the injection site after administering is unnecessary and could increase the risk of bleeding. Administering at a 90-degree angle is not recommended for enoxaparin injections. Rotating injection sites is important to prevent tissue damage and irritation.

4. 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.

5. A nurse is caring for a client who has a prescription for vancomycin 1 g IV every 12 hours. The client is scheduled to have the morning dose at 0700. The nurse should schedule the trough level to be drawn at which of the following times?

• A. 2100
• B. 900
• C. 1300
• D. 1800

Correct answer: D

Rationale: The trough level of vancomycin should be drawn just before the next dose is administered, typically about 30 minutes before the scheduled dose. Since the morning dose is at 0700, the trough level should be drawn at 1800. This timing ensures an accurate measurement of the lowest concentration of the drug in the client's system before the next dose is given. Choice A (2100) is too close to the next dose, choice B (900) is too early, and choice C (1300) is also too far from the next dose.
