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 client is prescribed simvastatin. Which instruction should the nurse provide during teaching?

• A. Take this medication in the morning.
• B. Avoid drinking grapefruit juice.
• C. Increase your intake of leafy green vegetables.
• D. Monitor your pulse daily while taking this medication.

Correct answer: B

Rationale: The correct answer is B: 'Avoid drinking grapefruit juice.' Grapefruit juice can increase the risk of toxicity when taken with simvastatin. Instructing the client to avoid grapefruit juice helps prevent this interaction. Choice A is incorrect because the timing of medication administration for simvastatin is usually in the evening. Choice C is unrelated to simvastatin therapy. Choice D is not necessary for monitoring while taking simvastatin.

3. A client who has undergone vein ligation and stripping to treat varicose veins should be instructed to do which of the following activities during discharge teaching?

• A. Remain sedentary for 2-3 days
• B. Walk for 1-2 hours each day
• C. Wear compression stockings only at night
• D. Elevate legs while sitting

Correct answer: B

Rationale: The correct answer is B: 'Walk for 1-2 hours each day.' After vein ligation and stripping, walking helps promote circulation and aids in the recovery process. Option A is incorrect as remaining sedentary for 2-3 days can lead to decreased circulation and potentially increase the risk of complications. Option C is incorrect because compression stockings should typically be worn during the day to support circulation. Option D is incorrect as elevating the legs while sitting is beneficial, but walking is more effective in promoting circulation and recovery in this case.

4. A client at 30 weeks of gestation reports constipation. Which of the following recommendations should the nurse make?

• A. Drink 1 liter of water per day.
• B. Take a laxative every morning.
• C. Increase your intake of refined grains.
• D. Walk for at least 30 minutes every day.

Correct answer: D

Rationale: The correct recommendation is to walk for at least 30 minutes every day. Walking stimulates intestinal motility, which can help relieve constipation during pregnancy. Option A is important for overall hydration but may not directly address constipation. Option B is not recommended without healthcare provider approval as some laxatives are contraindicated in pregnancy. Option C, increasing intake of refined grains, may exacerbate constipation due to lower fiber content.

5. A client is postoperative following hip replacement surgery. Which of the following instructions should the nurse include in preventing dislocation of the prosthesis?

• A. Cross your legs at the knees
• B. Avoid bending your hip more than 90 degrees
• C. Sit with your legs elevated
• D. Avoid placing a pillow under your knees

Correct answer: B

Rationale: To prevent dislocation of the prosthesis after hip replacement surgery, it is essential to avoid bending the hip more than 90 degrees. This precaution helps maintain the stability of the hip joint and reduces the risk of prosthesis dislocation. Crossing legs at the knees (Choice A) can increase pressure on the hip joint, leading to instability. Sitting with legs elevated (Choice C) and avoiding placing a pillow under the knees (Choice D) do not directly address the risk of prosthesis dislocation.
