NCLEX RN Predictor Exam Questions
Extract:
Question 1 of 5
A 47-year-old male client is admitted for colon surgery. Intravenous antibiotics are begun 2 hours prior to surgery. He has no known infection. The rationale for giving antibiotics prior to surgery is to:
Correct Answer: B
Rationale: Cathartic drugs promote evacuation of intestinal contents. The client undergoing intestinal surgery is at increased risk for infection from large numbers of anaerobic bacteria that inhabit the intestines. Administering antibiotics prophylactically can reduce the client's risk for infection. Antibiotics are indicated in the treatment of infections and have no effect on emotions. Antipyretics are useful in the treatment of elevated temperatures. Antibiotics would have an effect on infection, which causes temperature elevation, but would not directly affect such an elevation.
Question 2 of 5
A client is 2 hours post ventriculoperitoneal shunt placement. How should the nurse position the client?
Correct Answer: D
Rationale: Flat position on nonoperative side in the immediate postoperative period prevents pressure on shunt valve and rapid reduction in cerebrospinal fluid.
Question 3 of 5
The client is admitted with a suspected pulmonary embolism. Which diagnostic test is most likely to confirm the diagnosis?
Correct Answer: B
Rationale: A pulmonary angiogram is the gold standard for confirming pulmonary embolism, directly visualizing blockages in pulmonary arteries. Chest X-ray, ABGs, and ECG may support the diagnosis but are less specific.
Question 4 of 5
A 16-year-old diabetic girl has been selected as a cheerleader at her school. She asks the nurse whether she should increase her insulin when she is planning to attend cheerleading practice sessions lasting from 8 to 11 AM. The most appropriate answer would be:
Correct Answer: D
Rationale: A nurse can give this information to a client. Exercise makes insulin more efficient in moving more glucose into the cells. No more insulin is needed. Exercise makes insulin more efficient unless the diabetes is poorly controlled. Exercise makes insulin more efficient in moving more glucose into the cells.
Question 5 of 5
A client with tuberculosis has a prescription for Myambutol (ethambutol HCl). The nurse should tell the client to notify the doctor immediately if he notices:
Correct Answer: D
Rationale: Ethambutol can cause optic neuritis, leading to changes in color vision, a serious side effect requiring immediate reporting. Gastric distress is common, and red fluids are unrelated.
