1. What is the first step in preparing a blood transfusion?

A. Administer the blood via IV push
B. Verify the client's blood type before starting the transfusion
C. Warm the blood to body temperature before administration
D. Administer diuretics to prevent fluid overload

Correct answer: B

Rationale: The correct first step in preparing a blood transfusion is to verify the client's blood type before starting the transfusion. This step is crucial to ensure compatibility and prevent adverse reactions. Administering the blood via IV push (Choice A) is incorrect as it skips the essential step of verifying the blood type. Warming the blood to body temperature (Choice C) is important but comes after verifying the blood type. Administering diuretics (Choice D) is not part of the preparation process for a blood transfusion.

2. A nurse is reviewing the medical record of a client who is receiving warfarin for atrial fibrillation. Which of the following findings should the nurse report to the provider?

A. International normalized ratio (INR) of 2.5
B. Platelet count of 180,000/mm³
C. Prothrombin time (PT) of 12 seconds
D. Partial thromboplastin time (PTT) of 30 seconds

Correct answer: C

Rationale: A prothrombin time (PT) of 12 seconds is below the therapeutic range for warfarin and indicates a need for dosage adjustment. The correct answer is C. A normal International normalized ratio (INR) for a client on warfarin therapy is usually between 2.0 to 3.0; therefore, an INR of 2.5 is within the expected range. A platelet count of 180,000/mm³ is within the normal range (150,000 to 450,000/mm³) and does not require immediate reporting. A partial thromboplastin time (PTT) of 30 seconds is also within the normal range (25-35 seconds) and does not indicate a need for urgent action.

3. What are the signs and symptoms of a pulmonary embolism?

A. Sudden shortness of breath
B. Chest pain
C. Cough with blood
D. All of the above

Correct answer: D

Rationale: A pulmonary embolism can manifest with sudden shortness of breath, chest pain, and coughing up blood. These symptoms are classic presentations of a pulmonary embolism due to the blockage of blood flow to the lungs. Therefore, the correct answer is 'All of the above.' Each symptom alone can be seen in various other conditions, but when occurring together, they strongly suggest a pulmonary embolism. Sudden shortness of breath is due to decreased oxygenation, chest pain can result from the strain on the heart, and coughing with blood may indicate damage to the lung tissue. Choosing any single symptom would not encompass the full range of presentations seen in a pulmonary embolism.

4. What are the risk factors for developing hypertension?

A. High sodium diet and lack of physical activity
B. Low potassium intake and excessive alcohol consumption
C. Frequent exercise and low cholesterol diet
D. Smoking and family history

Correct answer: A

Rationale: The correct answer is A: High sodium diet and lack of physical activity. These are established risk factors for developing hypertension as they contribute to elevated blood pressure. Choice B, low potassium intake and excessive alcohol consumption, may also impact blood pressure but are not as strongly associated with hypertension as high sodium intake and lack of physical activity. Choice C, frequent exercise and a low cholesterol diet, are actually beneficial for reducing the risk of hypertension. Choice D, smoking and family history, are more closely linked to other health conditions such as cardiovascular diseases, rather than being primary risk factors for hypertension.

5. A client has developed phlebitis at the IV site. What should the nurse do first?

A. Apply a warm compress to the IV site
B. Discontinue the IV and notify the provider
C. Monitor the IV site for signs of infection
D. Administer an anti-inflammatory medication

Correct answer: B

Rationale: When a client develops phlebitis at the IV site, the priority action for the nurse is to discontinue the IV and notify the provider. Phlebitis is inflammation of the vein, and removing the IV can help prevent further complications. Applying a warm compress may provide symptomatic relief but does not address the root cause. Monitoring for infection is important, but immediate action to remove the source of inflammation is crucial. Administering an anti-inflammatory medication is not the first-line intervention for phlebitis; removal of the IV is necessary.
