Nursing Elites

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

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

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. A nurse is reviewing the medical record of a client who has diabetes mellitus and is receiving insulin. Which of the following findings should the nurse report to the provider?

• A. Hemoglobin A1c of 6%
• B. Fasting blood glucose of 90 mg/dL
• C. Blood glucose of 200 mg/dL
• D. Blood glucose of 100 mg/dL

Correct answer: C

Rationale: A blood glucose level of 200 mg/dL indicates hyperglycemia and should be reported for potential insulin adjustment.

3. A nurse is reinforcing discharge teaching with a client who is postoperative following an open radical prostatectomy. Which of the following instructions should the nurse include in the teaching?

• A. Perform Kegel exercises daily
• B. Perform light exercise for 3 hours each day
• C. Avoid bathing for 3 days
• D. Avoid sitting in a chair for more than 2 hours

Correct answer: A

Rationale: The correct answer is A: Perform Kegel exercises daily. After a radical prostatectomy, Kegel exercises are beneficial as they help strengthen the pelvic floor muscles, aiding in urinary control and recovery. Choice B is incorrect because recommending 3 hours of light exercise daily may not be suitable immediately postoperatively. Choice C is incorrect as personal hygiene, including bathing, is important for postoperative care. Choice D is incorrect because sitting for more than 2 hours does not specifically relate to the client's postoperative care needs.

4. A nurse is reinforcing teaching to a client with hypertension. What lifestyle change should be emphasized?

• A. Increase intake of sodium-rich foods
• B. Limit intake of high-fat foods
• C. Reduce intake of caffeinated beverages
• D. Eat high-protein foods to lower blood pressure

Correct answer: B

Rationale: The correct lifestyle change that should be emphasized for a client with hypertension is to limit the intake of high-fat foods. High-fat foods can contribute to high blood pressure, so reducing their consumption is important in managing hypertension. Choice A is incorrect because increasing intake of sodium-rich foods can worsen hypertension due to their effect on blood pressure. Choice C is incorrect as caffeinated beverages can also elevate blood pressure. Choice D is incorrect because while high-protein foods can be beneficial, they do not directly lower blood pressure like reducing high-fat foods would.

5. A client is learning about preventing hip dislocation before total hip arthroplasty. Which instruction should be included?

• A. Avoid bending the hip more than 90 degrees
• B. Avoid lying on the unaffected side
• C. Avoid crossing the legs at the knees
• D. Avoid keeping the legs in a neutral position

Correct answer: C

Rationale: The correct instruction to prevent hip dislocation after total hip arthroplasty is to avoid crossing the legs at the knees. This position can put stress on the hip joint and increase the risk of dislocation. Choices A, B, and D are incorrect. Bending the hip more than 90 degrees, lying on the unaffected side, or keeping the legs in a neutral position are not directly related to preventing hip dislocation in this context.
