Nursing Elites

1. 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.

2. A nurse assesses a young adult in the emergency room following a motor vehicle accident. Which of the following neurological signs is of most concern?

• A. Flaccid paralysis
• B. Pupils fixed and dilated
• C. Diminished spinal reflexes
• D. Reduced sensory responses

Correct answer: B

Rationale: Fixed, dilated pupils are a sign of increased intracranial pressure or brain injury, indicating a potentially serious neurological condition. Flaccid paralysis, although concerning, may not always indicate immediate life-threatening issues. Diminished spinal reflexes and reduced sensory responses are important neurological assessments but are not as acutely concerning as fixed, dilated pupils in this context.

3. An adolescent with intellectual disability is admitted for refusing to complete oral hygiene. A behavior modification program is recommended. Which reinforcement is best?

• A. Unit tasks for each omitted teeth brushing.
• B. Candy for each successfully completed hygiene task.
• C. Privilege restriction for refusing hygiene tasks.
• D. Preferred activities or tokens for compliance.

Correct answer: D

Rationale: The best reinforcement strategy in this scenario is providing preferred activities or tokens for compliance. Positive reinforcement is effective in behavior modification programs for individuals with intellectual disabilities. Offering preferred activities or tokens serves as a reward for completing the desired behavior, in this case, oral hygiene tasks. Choices A, B, and C do not focus on reinforcing the desired behavior with positive incentives. Choice A does not provide a positive reinforcement for compliance but rather focuses on the omission of a task. Choice B uses candy, which may not be ideal for oral hygiene. Choice C involves punishment rather than positive reinforcement.

4. The client is being taught to choose foods rich in potassium to prevent digitalis toxicity. Which choice indicates the client understands dietary needs?

• A. Three apricots
• B. Medium banana
• C. Naval orange
• D. Baked potato

Correct answer: D

Rationale: The correct answer is D: Baked potato. Baked potatoes are rich in potassium, which is essential in preventing digitalis toxicity by helping to maintain normal electrolyte levels. Apricots, bananas, and oranges are also sources of potassium, but a baked potato has a higher potassium content compared to the other options, making it a more effective choice for preventing digitalis toxicity.

5. A client with chronic kidney disease is prescribed erythropoietin. What lab value should the nurse monitor to evaluate the effectiveness of the therapy?

• A. White blood cell count.
• B. Hemoglobin level.
• C. Serum creatinine level.
• D. Platelet count.

Correct answer: B

Rationale: Erythropoietin therapy stimulates red blood cell production in clients with chronic kidney disease. Hemoglobin levels should be monitored to assess the effectiveness of the therapy and ensure the client is not developing anemia. Increased hemoglobin levels indicate successful treatment, whereas very high levels may suggest erythropoietin is overcorrecting the anemia. Monitoring the white blood cell count is not directly related to erythropoietin therapy for anemia. Serum creatinine level is used to assess kidney function rather than the effectiveness of erythropoietin therapy. Platelet count is not typically affected by erythropoietin therapy and is not a key indicator of its effectiveness.
