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. The nurse is preparing to administer digoxin to a patient who is newly admitted to the intensive care unit. The nurse reviews the patient’s admission electrolytes and notes a serum potassium level of 2.9 mEq/L. Which action by the nurse is correct?

• A. Administer the digoxin and monitor the patient’s electrocardiogram closely.
• B. Hold the digoxin dose and notify the provider of the patient’s lab values.
• C. Request an order for an intravenous bolus of potassium.
• D. Request an order for oral potassium supplements.

Correct answer: B

Rationale: In the scenario presented, the patient has a low serum potassium level, which can predispose the patient to digoxin toxicity. It is essential for the nurse to hold the digoxin dose and promptly notify the healthcare provider of the abnormal lab values. Option A is incorrect because administering digoxin without addressing the low potassium level can potentiate toxicity. Option C is inappropriate as potassium should not be given as an IV bolus, especially in the case of hypokalemia. Option D is incorrect because oral potassium supplements may not be sufficient for rapidly correcting severe hypokalemia in an acute care setting.

3. A client has just undergone insertion of a chest tube that is attached to a closed chest drainage system. Which action should the nurse plan to take in the care of this client?

• A. Assessing the client’s chest for crepitus every 24 hours
• B. Taping the connections between the chest tube and the drainage system
• C. Adding 20 mL of sterile water to the suction control chamber every shift
• D. Recording the volume of secretions in the drainage collection chamber every 24 hours

Correct answer: B

Rationale: The correct action for the nurse to take in caring for a client with a chest tube connected to a closed chest drainage system is to tape the connections between the chest tube and the drainage system. This is done to prevent accidental disconnection, ensuring the system functions properly. Assessing the client’s chest for crepitus should be done more frequently than once every 24 hours to monitor for any air leaks. Adding sterile water to the suction control chamber is not necessary every shift; it should be done as needed to maintain the appropriate water level. Recording the volume of secretions in the drainage collection chamber should be done more frequently than every 24 hours, with hourly monitoring during the first 24 hours after insertion and every 8 hours thereafter to assess for changes or complications.

4. A client with bladder cancer who underwent a complete cystectomy with ileal conduit is being assessed by a nurse. Which assessment finding should prompt the nurse to urgently contact the healthcare provider?

• A. The ileostomy is draining blood-tinged urine.
• B. There is serous sanguineous drainage on the surgical dressing.
• C. The ileostomy stoma appears pale and cyanotic.
• D. Oxygen saturations are 92% on room air.

Correct answer: C

Rationale: A pale or cyanotic appearance of the ileostomy stoma indicates compromised circulation, which can lead to necrosis if not promptly addressed. On the other hand, blood-tinged urine and serous sanguineous drainage are common following a complete cystectomy with ileal conduit. These findings do not typically indicate an urgent issue. An oxygen saturation of 92% on room air is slightly below the normal range but does not warrant urgent healthcare provider contact unless accompanied by significant respiratory distress or other concerning symptoms.

5. A client with chronic renal failure is receiving epoetin alfa (Epogen). The nurse should assess the client for which of the following complications?

• A. Hypertension.
• B. Hypotension.
• C. Hyperglycemia.
• D. Edema.

Correct answer: A

Rationale: The correct answer is A: Hypertension. Epoetin alfa (Epogen) is known to increase blood pressure by stimulating red blood cell production. Monitoring for hypertension is crucial to prevent complications such as heart failure or stroke. Choices B, C, and D are incorrect because hypotension, hyperglycemia, and edema are not typically associated with epoetin alfa therapy in clients with chronic renal failure.
