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 client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?

• A. Administer IV calcium gluconate.
• B. Administer sodium polystyrene sulfonate (Kayexalate).
• C. Administer insulin with dextrose.
• D. Restrict potassium intake in the client's diet.

Correct answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

3. A male client with HIV on saquinavir and other antiretrovirals reports increased hunger and thirst but weight loss. Which action should the nurse take?

• A. Use a glucometer to assess capillary glucose.
• B. Explain to the client that an increased dose of medication is needed.
• C. Reassure the client that weight will improve as viral load decreases.
• D. Teach the client how to measure his weight accurately.

Correct answer: A

Rationale: Increased thirst and hunger while losing weight may indicate hyperglycemia, a common side effect of saquinavir and other antiretrovirals. Using a glucometer to assess capillary glucose levels is essential to evaluate for hyperglycemia. Choice B is incorrect because increasing the dose of medication without assessing blood glucose levels can be dangerous. Choice C is incorrect because weight loss may not necessarily improve with viral load reduction and doesn't address the immediate concern of hyperglycemia. Choice D is irrelevant to the presenting symptoms and should not be a priority over assessing for hyperglycemia.

4. The nurse is caring for a client with a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Which intervention is most important for the nurse to implement?

• A. Encourage oral hydration
• B. Monitor for signs of dehydration
• C. Restrict fluid intake
• D. Administer IV fluids as prescribed

Correct answer: C

Rationale: In SIADH, there is excessive ADH secretion leading to water retention and dilutional hyponatremia. The most crucial intervention is to restrict fluid intake to prevent further fluid overload and worsening of hyponatremia. Encouraging oral hydration (choice A) would exacerbate the condition by adding more fluids. Monitoring for signs of dehydration (choice B) is not appropriate as the client is at risk of fluid overload. Administering IV fluids (choice D) would worsen the hyponatremia and should be avoided.

5. An older adult client with chronic emphysema is admitted to the emergency room with acute weakness, palpitations, and vomiting. Which information is most important for the nurse to obtain during the initial interview?

• A. Recent compliance with prescribed medications.
• B. Sleep patterns during the previous few weeks.
• C. History of smoking over the past 6 months.
• D. Activity level prior to the onset of symptoms.

Correct answer: A

Rationale: The correct answer is A: Recent compliance with prescribed medications. In a client with chronic emphysema experiencing acute symptoms, it is crucial to assess medication compliance as it directly impacts the management of the condition and could contribute to the current presentation. Ensuring that the client has been taking their prescribed medications can provide vital information to guide further treatment. Choices B, C, and D, although important in a comprehensive assessment, are not as immediately crucial as assessing medication compliance in this emergency situation.
