Nursing Elites

1. Before a client with renal failure undergoes hemodialysis, what should the nurse assess?

• A. Check the client's potassium levels
• B. Review the client's medication list
• C. Assess the client's peripheral pulses
• D. Monitor the client's urine output

Correct answer: A

Rationale: The correct answer is to check the client's potassium levels. Potassium levels are crucial to assess before hemodialysis in a client with renal failure because hyperkalemia (high potassium) is a common complication in these patients. Hemodialysis aims to remove excess potassium from the blood, making it essential to monitor potassium levels to determine the need for appropriate interventions. Reviewing the client's medication list (Choice B) is important for overall care but is not as directly relevant to the immediate concerns before hemodialysis. Assessing peripheral pulses (Choice C) and monitoring urine output (Choice D) are important aspects of nursing assessment but are not as directly related to the specific preparation needed before hemodialysis in a client with renal failure.

2. At 0600 while admitting a woman for a scheduled repeat cesarean section, the client tells the nurse that she drank a cup of coffee at 0400 because she wanted to avoid getting a headache. Which action should the nurse take first?

• A. Cancel the surgery
• B. Inform the anesthesia care provider
• C. Ask the client if she has had any other liquids
• D. Proceed with routine preparations

Correct answer: B

Rationale: Drinking liquids before surgery can increase the risk of aspiration during anesthesia. Therefore, the anesthesia care provider must be informed immediately to determine how to proceed, as this could delay or alter the surgical plan. Canceling the surgery without consulting the anesthesia care provider would be premature and could potentially lead to unnecessary actions. Asking the client if she has had any other liquids is important but not the first priority. Proceeding with routine preparations without addressing the potential issue of ingesting liquids before surgery could compromise the client's safety.

3. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

4. While changing a client's chest tube dressing, the nurse notes a cracking sensation when gentle pressure is applied to the skin at the insertion site. What should the nurse do next?

• A. Apply a pressure dressing at the chest tube site.
• B. Administer an oral antihistamine per PRN order.
• C. Assess the client for allergies to topical cleaning agents.
• D. Measure the area of crackling and swelling.

Correct answer: D

Rationale: Measuring the area of crackling and swelling is essential in monitoring the progression of subcutaneous emphysema, which can result from air leaking into the tissues around the chest tube insertion site. This technique helps evaluate the extent of the issue and guides further interventions. Applying a pressure dressing (choice A) might exacerbate the condition by trapping more air. Administering an oral antihistamine (choice B) is not indicated for subcutaneous emphysema. Assessing for allergies to topical cleaning agents (choice C) is not the priority in this situation compared to evaluating and managing the subcutaneous emphysema.

5. A client with a deep vein thrombosis (DVT) is prescribed enoxaparin. What teaching should the nurse provide?

• A. Rotate injection sites to prevent bruising.
• B. Administer the injection in the abdomen only.
• C. Report any unusual bleeding or bruising.
• D. Avoid contact sports to prevent injury.

Correct answer: C

Rationale: The correct teaching for a client prescribed enoxaparin for deep vein thrombosis (DVT) is to report any unusual bleeding or bruising. Enoxaparin is an anticoagulant, and these symptoms could indicate excessive anticoagulation. Choice A is incorrect because with enoxaparin, injections are usually given in the abdomen, not rotated to different sites. Choice D is not directly related to the medication but is a general precaution for individuals at risk of injury.
