1. What is the proper technique for obtaining a blood specimen from a central venous line?

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

2. Which of the following is an expected side effect of furosemide?

Correct answer: B

Rationale: The correct answer is B, Hypokalemia. Furosemide is a loop diuretic that works by increasing the excretion of water and electrolytes, including potassium, leading to hypokalemia. Choice A, Bradycardia, is incorrect because furosemide does not typically cause a decrease in heart rate. Choice C, Increased blood pressure, is incorrect as furosemide is actually used to lower blood pressure by reducing fluid volume. Choice D, Increased urine output, is a common effect of furosemide due to its diuretic action but is not an adverse side effect.

3. A nurse is collecting data from a school-age child who has sustained a skull fracture. Which of the following is a manifestation of increased intracranial pressure?

Correct answer: B

Rationale: Confusion, especially about one's own name, is a sign of increased intracranial pressure and should be addressed. Nausea and vomiting are common symptoms of increased intracranial pressure, but confusion about personal information is a more specific and critical indication that requires immediate attention. Rapid pulse may be a possible response to increased intracranial pressure, but it is not as specific as confusion about own name in this scenario.

4. A nurse is caring for a client who requests information about advance directives. Which of the following responses should the nurse make?

Correct answer: C

Rationale: The correct response is C: 'It includes end-of-life care instructions.' An advance directive is a legal document that outlines a client's preferences for medical treatment and end-of-life care in case they are unable to communicate. Choice A is incorrect because an advance directive focuses on healthcare decisions, not funeral arrangements. Choice B is incorrect as organ donation is a separate process from advance directives. Choice D is incorrect as advance directives do not provide legal guardianship rights, but rather specify healthcare wishes.

5. A nurse is caring for a client with a pressure ulcer and a serum albumin level of 3 g/dL. What should the nurse do first?

Correct answer: B

Rationale: Consulting with a dietitian is the priority as it ensures that the client receives a comprehensive nutritional assessment and an individualized plan to address the low serum albumin level and pressure ulcer. Increasing protein intake (choice A) and administering a protein supplement (choice C) may be part of the dietitian's recommendations but should not be done without proper assessment and guidance. Monitoring fluid and electrolyte balance (choice D) is important but not the first step in addressing the client's nutritional needs.
