1. Which lab value is critical for monitoring warfarin therapy?

• A. Monitor INR
• B. Monitor platelet count
• C. Monitor sodium levels
• D. Monitor calcium levels

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

2. A nurse is caring for a client who is at risk for pressure ulcers. Which of the following interventions should the nurse implement?

• A. Turn the client every 2 hours
• B. Use a donut-shaped cushion when sitting
• C. Elevate the head of the bed to 45 degrees
• D. Massage reddened areas to increase circulation

Correct answer: A

Rationale: The correct intervention for preventing pressure ulcers in a client at risk is to turn the client every 2 hours. This helps relieve pressure on bony prominences, improving circulation and preventing tissue damage. Using a donut-shaped cushion can actually increase pressure on the skin and worsen the risk of pressure ulcers. Elevating the head of the bed to 45 degrees is beneficial for preventing aspiration in some cases but does not directly address pressure ulcer prevention. Massaging reddened areas can further damage the skin and increase the risk of pressure ulcer development by causing friction and shearing forces.

3. A nurse is caring for an adult client who has prescriptions for multiple medications. Which of the following is an age-related change that increases the risk for adverse effects from these medications?

• A. Rapid gastric emptying
• B. Prolonged medication half-life
• C. Increased medication elimination
• D. Decreased medication sensitivity

Correct answer: B

Rationale: The correct answer is B: Prolonged medication half-life. As clients age, their metabolism tends to slow down, leading to a prolonged half-life of medications in the body. This extended presence of drugs can increase the risk for adverse effects as the substances accumulate. Choice A, rapid gastric emptying, is not an age-related change and actually decreases the time medications spend in the stomach, potentially reducing their effectiveness. Choice C, increased medication elimination, is not an age-related change either; in fact, aging can lead to decreased renal function, affecting drug elimination. Choice D, decreased medication sensitivity, is not an age-related change that directly increases the risk for adverse effects; rather, it may lead to requiring higher doses for effectiveness but does not inherently increase the risk of adverse effects.

4. A nurse is providing dietary teaching to a client who has chronic kidney disease. Which of the following food choices by the client indicates an understanding of the teaching?

• A. Peanut butter and jelly sandwich
• B. Grilled chicken and rice
• C. Tomato soup with saltine crackers
• D. Baked fish and steamed vegetables

Correct answer: D

Rationale: The correct answer is D, baked fish and steamed vegetables. These food choices are low in potassium and phosphorus, which is important for clients with chronic kidney disease to manage their condition effectively. Grilled chicken and rice (choice B) may be high in phosphorus, tomato soup with saltine crackers (choice C) is high in sodium, and a peanut butter and jelly sandwich (choice A) contains high levels of potassium, all of which are not ideal choices for individuals with chronic kidney disease.

5. A healthcare professional is assessing a client who has chronic kidney disease. Which of the following findings should the healthcare professional report to the provider?

• A. Urine output of 80 mL/hr
• B. Blood pressure of 140/90 mm Hg
• C. Serum creatinine 2.8 mg/dL
• D. Heart rate of 72/min

Correct answer: C

Rationale: The correct answer is C. A serum creatinine level of 2.8 mg/dL indicates impaired kidney function and should be reported to the healthcare provider. Elevated serum creatinine levels are indicative of decreased kidney function and potential progression of chronic kidney disease. Choices A, B, and D are within normal ranges and do not signify immediate concerns related to kidney disease. Urine output of 80 mL/hr is appropriate, a blood pressure of 140/90 mm Hg is considered prehypertensive but not acutely concerning, and a heart rate of 72/min falls within the normal range.
