Nursing Elites

1. A client receiving warfarin (Coumadin) therapy should have which of the following laboratory results reviewed to evaluate the effectiveness of the therapy?

• A. Complete blood count (CBC).
• B. Prothrombin time (PT).
• C. International normalized ratio (INR).
• D. Partial thromboplastin time (PTT).

Correct answer: C

Rationale: The correct answer is C: International normalized ratio (INR). The INR is the most appropriate laboratory result to review when evaluating the effectiveness of warfarin (Coumadin) therapy. Warfarin is an anticoagulant medication, and the INR helps determine if the dosage is within a therapeutic range to prevent clotting or bleeding complications. Choice A, a Complete Blood Count (CBC), provides information about the cellular components of blood but does not directly assess the anticoagulant effects of warfarin. Choice B, Prothrombin time (PT), measures the time it takes for blood to clot but is not as specific for monitoring warfarin therapy as the INR. Choice D, Partial Thromboplastin Time (PTT), evaluates the intrinsic pathway of coagulation and is not the primary test used to monitor warfarin therapy.

2. After a urography, a client is instructed by a nurse. Which instruction should the nurse include in this client’s discharge teaching?

• A. Avoid direct contact with your urine for 24 hours until the dye clears.
• B. You may experience dribbling of urine for several weeks post-procedure.
• C. Drink at least 3 liters of fluids today to assist in dye elimination.
• D. Your skin may turn slightly yellow from the dye used in this procedure.

Correct answer: C

Rationale: It is important for the client to increase fluid intake to aid in the rapid elimination of the potentially nephrotoxic dye used in urography. This instruction will help prevent any adverse effects related to the dye. Choices A, B, and D are incorrect because the dye used in urography is not radioactive, so there is no need to avoid direct contact with urine, urine dribbling is not a common post-procedure occurrence, and the dye should not cause the client's skin to change color.

3. A patient is taking a thiazide diuretic and reports anorexia and fatigue. The nurse suspects which electrolyte imbalance in this patient?

• A. Hypercalcemia
• B. Hypocalcemia
• C. Hyperkalemia
• D. Hypokalemia

Correct answer: D

Rationale: The correct answer is D: Hypokalemia. Thiazide diuretics lead to potassium loss, potentially causing hypokalemia. Anorexia and fatigue are common manifestations of hypokalemia. Hypercalcemia (choice A) and hypocalcemia (choice B) are not directly associated with thiazide diuretics. Hyperkalemia (choice C) is less likely than hypokalemia to be caused by thiazide diuretics.

4. A client tells the nurse that he has been experiencing frequent heartburn and has been 'living on antacids.' For which acid-base disturbance does the nurse recognize a risk?

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

Correct answer: B

Rationale: The correct answer is B: Metabolic alkalosis. In this scenario, the client's frequent use of antacids containing alkaline components can lead to an excess of bicarbonate in the body, causing metabolic alkalosis. Oral antacids work by neutralizing stomach acid, potentially leading to an alkaline shift in the body's pH balance. Choices A, C, and D are incorrect. Metabolic acidosis is not typically associated with antacid use. Respiratory acidosis and respiratory alkalosis are related to respiratory system dysfunction rather than antacid ingestion.

5. A nurse plans care for an older adult client. Which interventions should the nurse include in this client’s plan of care to promote kidney health? (Select all that apply.)

• A. Ensure adequate fluid intake.
• B. Leave the bathroom light on at night.
• C. Encourage use of the toilet every 6 hours.
• D. A & B

Correct answer: D

Rationale: The correct interventions to promote kidney health in an older adult client include ensuring adequate fluid intake to maintain hydration and leaving the bathroom light on at night to promote safe ambulation. Adequate hydration supports kidney function and helps prevent urinary tract infections. Encouraging the use of the toilet every 6 hours is not specific to kidney health and may not be individualized to the client's needs. Providing thorough perineal care after each voiding is important for hygiene but not directly related to promoting kidney health. Assessing for urinary retention and urinary tract infections is crucial but falls under assessment rather than interventions for promoting kidney health specifically.
