Nursing Elites

1. A healthcare provider is reviewing the laboratory report of a client who is receiving heparin therapy for a deep vein thrombosis. Which of the following lab values indicates a therapeutic response to the therapy?

• A. PT of 12 seconds
• B. aPTT of 70 seconds
• C. Platelets of 150,000/mm3
• D. INR of 1.5

Correct answer: B

Rationale: An aPTT of 70 seconds is within the therapeutic range for a client receiving heparin therapy. The activated partial thromboplastin time (aPTT) is the most sensitive test to monitor heparin therapy. A therapeutic aPTT range for a client receiving heparin is usually 1.5 to 2.5 times the control value. Choices A, C, and D are not indicators of a therapeutic response to heparin therapy. PT measures the extrinsic pathway of coagulation and is not specific to monitoring heparin therapy. Platelet count is important to monitor for heparin-induced thrombocytopenia, but it does not indicate the therapeutic response to heparin therapy. INR is used to monitor warfarin therapy, not heparin therapy.

2. What are the main differences between a stroke caused by ischemia and one caused by hemorrhage?

• A. Blockage in a blood vessel supplying the brain
• B. Bleeding in the brain due to a ruptured aneurysm
• C. Administering thrombolytics if within the treatment window
• D. Avoiding anticoagulants and preparing for surgery

Correct answer: A

Rationale: The correct answer is A: "Blockage in a blood vessel supplying the brain." Ischemic stroke is caused by a blockage in a blood vessel supplying the brain, leading to reduced blood flow. Hemorrhagic stroke, on the other hand, is caused by bleeding in the brain due to a ruptured blood vessel. Choices B, C, and D are incorrect. Administering thrombolytics, avoiding anticoagulants, and preparing for surgery are specific management strategies that may apply to ischemic or hemorrhagic strokes but do not define the main differences between the two types of strokes.

3. When caring for a patient with a nasogastric (NG) tube, what is the most appropriate intervention to prevent aspiration?

• A. Flush the NG tube with water before each feeding.
• B. Check the placement of the NG tube before each feeding.
• C. Elevate the head of the bed to 30-45 degrees.
• D. Provide the patient with oral care every 4 hours.

Correct answer: C

Rationale: Elevating the head of the bed to 30-45 degrees is the most appropriate intervention to prevent aspiration in a patient with an NG tube. This position helps reduce the risk of regurgitation and aspiration by promoting the proper flow of contents through the gastrointestinal tract and minimizing the chances of stomach contents entering the airway. Flushing the NG tube with water before each feeding may not directly prevent aspiration. Checking the placement of the NG tube is important but does not specifically address the prevention of aspiration. Providing oral care every 4 hours is essential for maintaining oral hygiene but is not directly related to preventing aspiration in a patient with an NG tube.

4. A nurse is assessing a client who is receiving a continuous IV infusion of heparin. Which of the following findings should the nurse report to the provider?

• A. Report any urine output greater than 30 mL/hr.
• B. Bruising on the arms and legs.
• C. Positive Trousseau's sign.
• D. Urine output of 60 mL/hr.

Correct answer: B

Rationale: The correct answer is B. Bruising on the arms and legs is a sign of bleeding, which is a serious complication of heparin therapy and should be reported immediately to the provider. Option A is incorrect as urine output greater than 30 mL/hr is a normal finding. Option C, positive Trousseau's sign, is associated with hypocalcemia, not heparin therapy. Option D, urine output of 60 mL/hr, is within the normal range and does not indicate a complication of heparin therapy.

5. The client has a do-not-resuscitate (DNR) order. The family asks the nurse to ignore the DNR if the client codes. What is the nurse's responsibility?

• A. Follow the family's wishes
• B. Explain that the DNR must be honored
• C. Ignore the DNR and proceed with CPR
• D. Perform CPR if the client codes

Correct answer: B

Rationale: The correct answer is B: 'Explain that the DNR must be honored.' The nurse's responsibility is to follow the DNR order, as it is a legal and ethical obligation. Choice A is incorrect because following the family's wishes would go against the established DNR order. Choice C is incorrect as ignoring the DNR order is not appropriate. Choice D is also incorrect as performing CPR would be contrary to the client's expressed wishes in the DNR order.
