Nursing Elites

1. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.

2. A postoperative client returns to the nursing unit following a ureter lithotomy via a flank incision. Which potential nursing problem has the highest priority when planning nursing care for this client?

• A. Ineffective airway clearance
• B. Altered nutrition less than body requirements
• C. Fluid volume excess
• D. Activity intolerance

Correct answer: A

Rationale: The correct answer is 'Ineffective airway clearance.' Following a ureter lithotomy via a flank incision, the highest priority nursing problem is ensuring the client's airway remains clear. This is crucial for effective breathing and oxygenation. Altered nutrition, fluid volume excess, and activity intolerance are important to address but are of lower priority compared to maintaining a clear airway postoperatively.

3. The nurse is caring for a client who is receiving a continuous intravenous infusion of heparin. Which laboratory value should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Partial thromboplastin time (PTT)
• D. Hemoglobin level

Correct answer: C

Rationale: The correct answer is C. Partial thromboplastin time (PTT) is the laboratory value that should be monitored to evaluate the effectiveness of heparin therapy. PTT reflects the intrinsic pathway of coagulation and is specifically sensitive to heparin's anticoagulant effects. Monitoring the PTT helps ensure that the client is within the therapeutic range to prevent clot formation without increasing the risk of bleeding. Choices A, B, and D are incorrect because while they are important laboratory values in other contexts, they are not specifically used to monitor the effectiveness of heparin therapy.

4. A 17-year-old female is seen in the school clinic for an evaluation of abdominal pain and dysmenorrhea. The client's last menstrual period was 3 weeks ago, and her vital signs are within normal limits. Which action should the nurse take first?

• A. Refer the client to a healthcare provider for a pelvic examination
• B. Notify the parents that the client needs to be picked up from school
• C. Determine the date of the client's last menstrual period
• D. Ask the client to lie down for a pelvic examination

Correct answer: A

Rationale: The correct action the nurse should take first is to refer the client to a healthcare provider for a pelvic examination. This is important to rule out serious conditions that may be causing the abdominal pain and dysmenorrhea. While notifying the parents, determining the date of the client's last menstrual period, and asking the client to lie down for a pelvic examination could be necessary steps, the priority is to ensure a proper evaluation by a healthcare provider to address the client's presenting symptoms effectively.

5. The nurse is preparing to administer a unit of packed red blood cells (PRBCs) to a client. Which action is most important for the nurse to take?

• A. Verify the client's blood type
• B. Ensure the PRBCs are warm
• C. Check the client's vital signs
• D. Obtain the client's consent

Correct answer: A

Rationale: Verifying the client's blood type is crucial before administering PRBCs to ensure compatibility and prevent transfusion reactions. Checking the client's blood type is essential in blood transfusions. Ensuring the PRBCs are warm is not a priority as the temperature should be within a specific range regardless of the client's preference. Checking the client's vital signs is important but not as crucial as verifying the blood type before a blood transfusion. Obtaining the client's consent is important for any procedure but does not directly impact the safety and success of administering PRBCs.
