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. A nurse has a prescription to discontinue a client’s nasogastric tube. The nurse auscultates the client’s bowel sounds, positions the client properly, and flushes the tube with 15 mL of air to clear secretions. The nurse then instructs the client to take a deep breath and:

• A. Exhale during tube removal
• B. Bear down during tube removal
• C. Hold the breath during tube removal
• D. Breathe normally during tube removal

Correct answer: C

Rationale: The correct answer is to instruct the client to hold their breath during tube removal. This is because the airway may be temporarily obstructed during the removal process. By holding their breath, the client can help prevent aspiration or discomfort during the removal of the nasogastric tube. Choices A, B, and D are incorrect because exhaling, bearing down, or breathing normally during tube removal may not provide the necessary protection against aspiration or discomfort that holding the breath does.

3. Which of the following conditions is the most significant risk factor for the development of type 2 diabetes mellitus?

• A. Cigarette smoking.
• B. High-cholesterol diet.
• C. Obesity.
• D. Hypertension.

Correct answer: C

Rationale: Obesity is the most significant risk factor for developing type 2 diabetes mellitus due to its role in insulin resistance. Excess body fat, especially around the abdomen, leads to increased production of inflammatory markers and hormones that can cause insulin resistance. While cigarette smoking, high-cholesterol diet, and hypertension can contribute to health issues, they are not as directly linked to the development of type 2 diabetes mellitus as obesity.

4. A client has just had a central line catheter placed that is specific for hemodialysis. What is the most appropriate action by the nurse?

• A. Use the catheter for the next laboratory blood draw.
• B. Monitor the central venous pressure through this line.
• C. Access the line for the next intravenous medication.
• D. Place a heparin or heparin/saline dwell after hemodialysis.

Correct answer: D

Rationale: The most appropriate action for the nurse after a central line catheter placement for hemodialysis is to place a heparin or heparin/saline dwell after hemodialysis treatment. This helps prevent clot formation in the line and maintain patency for future use. Using the catheter for blood draws is not recommended as it may increase the risk of infection. Monitoring central venous pressure is not indicated with this type of catheter. Accessing the line for medications is also not recommended to prevent complications and ensure the line is solely used for hemodialysis purposes.

5. What action should the nurse take for a female patient experiencing vaginal itching and discharge while taking trimethoprim-sulfamethoxazole (TMP-SMZ) (Bactrim, Septra) for a urinary tract infection?

• A. Ask the patient if she might be pregnant.
• B. Reassure the patient that this is a normal side effect.
• C. Report a possible superinfection to the provider.
• D. Suspect that the patient is having a hematologic reaction.

Correct answer: C

Rationale: The correct action for the nurse to take in this situation is to report a possible superinfection to the healthcare provider. Vaginal itching and discharge can indicate a superinfection, which is a secondary infection that can occur while taking antibiotics. It is essential to notify the provider so that appropriate treatment can be initiated. Asking about pregnancy is not relevant in this context as vaginal itching and discharge are not typical signs of pregnancy. Simply reassuring the patient that these symptoms are normal side effects is inadequate as they may indicate a more serious issue like a superinfection. Suspecting a hematologic reaction is not warranted based on the symptoms described.
