NCLEX CRUSADE ACADEMY TEST - 2 GENERAL DIAGNOSTICS TEST I

1. A nurse prepares a patient for an invasive diagnostic procedure. What is the priority nursing action?. Verify the patient has eaten within 2 hours. Ensure informed consent is signed and understanding verified. Provide post operative education. Administer prophylactic antibiotics.

2. Which nursing action is part of the pre procedure safety verification for diagnostic procedures?. Ensuring the patient drinks fluids. Confirming NPO status, baseline labs, and allergies. Administering sedation. Starting postoperative teaching.

3. A biopsy performed using a needle to withdraw cells or fluid is called: Punch biopsy. Brush biopsy. Aspiration biopsy. Incisional biopsy.

4. Which post biopsy instruction is essential to reduce bleeding risk?. Resume normal activity immediately. Avoid anticoagulants such as aspirin or warfarin. Increase exercise. Restrict fluids.

5. What position is commonly used during a kidney biopsy?. Supine position. Prone position. Sims position. Trendelenburg position.

6. After a renal biopsy, what finding requires immediate reporting?. Mild soreness at the biopsy site. Clear urine. Decreased urine output or hematuria. Slight fatigue.

7. Why should ultrasound or simple X ray usually be performed before contrast CT?. CT scans cannot detect bones. Contrast may obscure later imaging studies. Ultrasound is more invasive. CT uses magnetic fields.

8. A nurse prepares a patient for an abdominal ultrasound. Which instruction is appropriate?. Eat a high fat meal before the test. Remain NPO for 4–8 hours before the exam. Drink large volumes of water immediately before. Take laxatives.

9. Pelvic ultrasound preparation usually requires: A completely empty bladder. A full bladder. Fasting for 24 hours. High protein diet.

10. Which contrast agent is commonly used in CT scans?. Gadolinium. Iodine. Albumin. Glucose.

11. What laboratory values must be assessed before administering contrast dye?. Hemoglobin and hematocrit. Sodium and potassium. BUN and creatinine. Platelet count.

12. Which symptom after contrast administration is expected and does NOT require intervention?. Rash and hives. Dyspnea. Metallic taste in the mouth. Severe hypotension.

13. Which symptom indicates an adverse contrast reaction requiring intervention?. Warm sensation. Metallic taste. Dyspnea and tachycardia. Brief nausea.

14. After receiving IV contrast, what nursing intervention helps protect kidney function?. Restrict fluids. Encourage fluids. Restrict urination. Provide high protein foods.

15. Which imaging modality uses non ionizing radiation and strong magnetic fields?. CT scan. X ray. MRI. Fluoroscopy.

16. Which patient should NOT undergo MRI?. Patient with pacemaker. Patient with hypertension. Patient with diabetes. Patient with anemia.

17. Why must metal objects be removed before MRI?. They block radiation. They increase sound levels. Magnetic attraction can cause injury. They interfere with contrast dye.

18. What imaging method provides real time visualization of organ movement?. MRI. Fluoroscopy. Ultrasound. PET.

19. After a barium fluoroscopy exam, which intervention is appropriate?. Encourage laxatives. Restrict bowel movements. Provide diuretics. Encourage bed rest.

20. PET scans primarily evaluate: Bone fractures. Blood flow and metabolic activity. Muscle strength. Oxygen saturation.

21. PET imaging uses which mechanism to detect abnormalities?. Magnetic resonance. Radioactive isotopes. Sound waves. Electrical impulses.

22. A patient scheduled for elective surgery has a WBC count of 12.3. What is the nurse’s priority?. Document the result. Teach breathing exercises. Notify the surgeon immediately. Continue preparation.

23. Following a renal biopsy, which patient statement indicates correct understanding?. I can walk immediately. I will restrict fluids. I must remain supine in bed. I should exercise.

24. What is the most important radiation safety measure for women of childbearing age?. Fasting. Pregnancy test verification. Hydration. Sedation.

25. Which imaging modality uses sound waves?. CT. MRI. Ultrasound. PET.
