Nursing Elites

1. A client is receiving warfarin for atrial fibrillation. Which of the following laboratory tests should the nurse expect to be ordered to monitor the effect of warfarin?

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

Correct answer: B

Rationale: The correct answer is B: International normalized ratio (INR). When a client is on warfarin therapy, the INR is monitored regularly to assess the anticoagulant effects of the medication. A therapeutic INR range for most indications is between 2.0 to 3.0. Choices A, C, and D are not typically used to monitor the effect of warfarin. Platelet count assesses the number of platelets in the blood, PT measures the clotting time of plasma, and PTT evaluates the intrinsic pathway of coagulation.

2. A nurse is caring for a client who has a pressure ulcer. Which of the following findings should the nurse report to the provider?

• A. Eschar
• B. Slough
• C. Granulation tissue
• D. Undermining

Correct answer: D

Rationale: The correct answer is D, 'Undermining.' Undermining occurs when the tissue under the wound edges erodes, indicating poor healing progress. This finding should be reported to the provider as it suggests delayed wound healing and may require intervention. Choice A, 'Eschar,' is a thick, hard, black/brown necrotic tissue that forms over a wound. While it indicates a non-healing wound, it is not as concerning as undermining. Choice B, 'Slough,' is a soft, moist, yellow/white tissue that is also a sign of necrosis. While the presence of slough indicates the need for wound cleaning and debridement, it is not as critical to report as undermining. Choice C, 'Granulation tissue,' is new tissue that forms during wound healing and is a positive sign. The presence of granulation tissue indicates that the wound is progressing through the healing stages and is not a finding that requires immediate reporting to the provider.

3. A nurse is providing discharge teaching to a client who is postoperative following a total hip arthroplasty. Which of the following instructions should the nurse include?

• A. Cross your legs when sitting to increase circulation.
• B. Bend at the waist when picking up objects.
• C. Avoid crossing your legs when sitting.
• D. Avoid using a raised toilet seat.

Correct answer: C

Rationale: The correct answer is C: 'Avoid crossing your legs when sitting.' After a total hip arthroplasty, it is important for clients to avoid crossing their legs to prevent complications such as dislocation. Crossing the legs can put strain on the new hip joint, increasing the risk of dislocation. Choice A is incorrect as crossing legs can be harmful. Choice B is incorrect as bending at the waist can strain the hip joint, leading to complications. Choice D is incorrect as using a raised toilet seat is recommended after hip surgery to prevent excessive bending at the hip joint.

4. A client has a new prescription for spironolactone. Which of the following instructions should the nurse include?

• A. Take this medication with a potassium supplement.
• B. Avoid foods that contain potassium.
• C. Limit your fluid intake while taking this medication.
• D. Take this medication on an empty stomach.

Correct answer: B

Rationale: The correct answer is B because spironolactone is a potassium-sparing diuretic, which means it helps the body retain potassium. Instructing the client to avoid foods high in potassium helps prevent hyperkalemia, a potential side effect of spironolactone. Choice A is incorrect because taking spironolactone with a potassium supplement can increase the risk of hyperkalemia. Choice C is not directly related to spironolactone use. Choice D is also incorrect as spironolactone does not need to be taken on an empty stomach.

5. A healthcare professional is preparing to administer an IV fluid bolus of 500 mL over 4 hours to a client who is dehydrated. The healthcare professional should set the IV pump to deliver how many mL/hr?

• A. 75 mL/hr.
• B. 100 mL/hr.
• C. 125 mL/hr.
• D. 150 mL/hr.

Correct answer: C

Rationale: Setting the IV pump to 125 mL/hr ensures the correct infusion rate for delivering 500 mL over 4 hours. To calculate the mL/hr rate, divide the total volume to be infused (500 mL) by the total time for infusion (4 hours): 500 mL / 4 hours = 125 mL/hr. Choice A (75 mL/hr) is too low and would result in an insufficient infusion rate, potentially delaying fluid resuscitation. Choice B (100 mL/hr) would also be too low and not deliver the fluid within the specified time frame. Choice D (150 mL/hr) is too high and would infuse the fluid too quickly, potentially causing fluid overload and complications.
