Nursing Elites

1. A nurse is assessing a client who has right-sided heart failure. Which of the following findings should the nurse expect?

• A. Elevated blood glucose.
• B. Decreased urine output.
• C. Dependent edema.
• D. Jaundice.

Correct answer: C

Rationale: The correct answer is C: Dependent edema. In right-sided heart failure, the heart is unable to effectively pump blood to the lungs for oxygenation, leading to fluid accumulation in the systemic circulation. This fluid backs up in the venous system, causing increased pressure in the veins of the body, resulting in dependent edema, usually starting in the lower extremities. Elevated blood glucose (choice A) is not directly related to right-sided heart failure. Decreased urine output (choice B) may occur in conditions like acute kidney injury but is not a specific finding of right-sided heart failure. Jaundice (choice D) is more commonly associated with liver dysfunction, not typically seen in right-sided heart failure.

2. A nurse is caring for a client who has a prescription for metoprolol. For which of the following findings should the nurse withhold the medication?

• A. Heart rate 56/min.
• B. Oxygen saturation 93%.
• C. Respiratory rate 18/min.
• D. Blood pressure 118/74 mm Hg.

Correct answer: A

Rationale: The correct answer is A: Heart rate 56/min. Metoprolol, a beta blocker, should be withheld if the client's heart rate is below 60/min to prevent further bradycardia. Choices B, C, and D are within normal ranges and do not indicate a need to withhold metoprolol.

3. How should a healthcare professional respond to a patient with diabetic ketoacidosis (DKA)?

• A. Administer insulin
• B. Administer IV fluids
• C. Monitor blood glucose
• D. All of the above

Correct answer: D

Rationale: When managing a patient with diabetic ketoacidosis (DKA), it is crucial to administer insulin to lower blood sugar levels, administer IV fluids to correct dehydration and electrolyte imbalances, and monitor blood glucose levels regularly to ensure they are within the target range. Therefore, all of the above options are essential components of the comprehensive treatment plan for DKA. Administering insulin alone may lower blood sugar levels but will not address the fluid and electrolyte imbalances seen in DKA. Similarly, administering IV fluids alone may help with dehydration but will not address the high blood sugar levels or the need for insulin. Monitoring blood glucose alone is not sufficient to treat DKA; it must be accompanied by appropriate interventions to address the underlying causes and complications of the condition.

4. A nurse is teaching a client who is taking warfarin about food and medication interactions. Which of the following foods should the nurse instruct the client to avoid?

• A. Tomatoes
• B. Apples
• C. Broccoli
• D. Green leafy vegetables

Correct answer: D

Rationale: Correct Answer: Green leafy vegetables - Green leafy vegetables are high in vitamin K, which can interfere with the effectiveness of warfarin. Tomatoes, apples, and broccoli are not contraindicated with warfarin therapy. While they are healthy choices, they do not have a significant impact on warfarin's effectiveness.

5. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.
