Nursing Elites

1. A nurse is planning care for a client who has chronic kidney disease. Which finding indicates the need for hemodialysis?

• A. BUN 14 mg/dL
• B. Serum potassium 4.2 mEq/L
• C. Serum creatinine 5 mg/dL
• D. Serum calcium 9 mg/dL

Correct answer: C

Rationale: The correct answer is C. A serum creatinine level of 5 mg/dL is significantly elevated and indicates the need for hemodialysis to help filter waste products from the blood. Elevated creatinine levels suggest impaired kidney function and the inability to effectively filter waste from the body. Choices A, B, and D are within normal ranges and do not indicate the need for immediate hemodialysis in a client with chronic kidney disease.

2. A nurse is caring for a client who is hyperventilating and has the following ABG results: pH 7.50, PaCO2 29 mm Hg, and HCO3- 25 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. In this scenario, the client is hyperventilating, leading to excessive elimination of carbon dioxide. As a result, the PaCO2 decreases, causing a decrease in hydrogen ion concentration and an increase in pH, resulting in respiratory alkalosis. Choice A, Respiratory acidosis, is incorrect because the ABG results show a low PaCO2, not an elevated one. Choices C and D, Metabolic acidosis and Metabolic alkalosis, do not align with the ABG results provided, which point towards a respiratory, not metabolic, imbalance.

3. A healthcare professional is preparing to administer heparin 8,000 units subcutaneously every eight hrs. The amount available is heparin injection 10,000 units/mL. How many milliliters should the healthcare professional administer per dose?

• A. 0.7 mL
• B. 0.8 mL
• C. 1.0 mL
• D. 1.2 mL

Correct answer: B

Rationale: Calculation: 8000 units / 10,000 units per mL = 0.8 mL. To correctly administer the prescribed dose of 8000 units, the healthcare professional should draw up 0.8 mL from the 10,000 units/mL vial. Options A, C, and D are incorrect as they do not accurately reflect the calculation based on the available concentration of heparin.

4. A healthcare professional is preparing to administer a dose of warfarin. Which of the following actions should the healthcare professional take?

• A. Verify INR levels
• B. Administer with food
• C. Monitor blood glucose levels
• D. Assess liver function

Correct answer: A

Rationale: Corrected Rationale: When administering warfarin, it is crucial to verify the patient's INR levels. INR monitoring is essential to ensure that the patient is receiving the correct dose of warfarin for their condition and to minimize the risk of bleeding. Choices B, C, and D are incorrect because administering warfarin with food, monitoring blood glucose levels, and assessing liver function are not directly related to the safe administration and monitoring of warfarin therapy.

5. A nurse is providing education to a client about a new prescription for digoxin. Which of the following should be included?

• A. Monitor for increased heart rate
• B. Take the medication at the same time every day
• C. It should be stopped abruptly
• D. Avoid potassium-rich foods

Correct answer: B

Rationale: The correct answer is B: 'Take the medication at the same time every day.' Clients should take digoxin at the same time each day to maintain consistent therapeutic levels, enhancing the drug's effectiveness and minimizing fluctuations in blood concentration. Choice A is incorrect because digoxin, as a medication, may actually help in controlling the heart rate. Choice C is incorrect as digoxin should never be stopped abruptly due to the risk of rebound effects and worsening of the condition. Choice D is unrelated to digoxin therapy, as it is more relevant to medications like potassium-sparing diuretics.
