NCLEX RN Exam Questions Questions
Extract:
Question 1 of 5
The nurse is preparing to administer a dose of vancomycin (Vancocin) IV. Which assessment is most important before administration?
Correct Answer: B
Rationale: Vancomycin is nephrotoxic, so renal function tests (e.g., creatinine) are critical before administration to prevent kidney damage. Liver tests, WBC, and platelets are less directly related.
Question 2 of 5
The nurse is teaching a client with osteoporosis about dietary modifications. Which food should the client be encouraged to include?
Correct Answer: C
Rationale: Dairy products are rich in calcium, essential for bone health in osteoporosis. Citrus fruits provide vitamin C, red meat offers iron, and whole grains supply fiber, but they are less critical for bone density.
Question 3 of 5
The nurse is teaching a client with a new colostomy about appliance care. Which instruction should be included?
Correct Answer: B
Rationale: Emptying the colostomy pouch when one-third to one-half full prevents leakage and skin irritation. Changing every 12 hours is excessive, soap may leave residue, and lotion can interfere with adhesion.
Question 4 of 5
A 20-year-old male client is being treated for protein deficiency. If he likes all of the following foods, which one would the nurse recommend to increase in the diet?
Correct Answer: C
Rationale: Cantaloupe is a good source of carbohydrates, vitamin C, and vitamin A. Rice contains about 4 g of protein per 200 g. Chicken contains 35 g protein per breast. Chicken is a rich source of vitamin B6 (pyridoxine), which is needed for adequate protein synthesis. As protein intake increases, vitamin B6 intake must also be increased. Vitamin B6 is a coenzyme in amino acid metabolism. Green beans only contain 2 g of protein per cup.
Question 5 of 5
The mother of a male child with cystic fibrosis tells the nurse that she hopes her son's children won't have the disease. The nurse is aware that:
Correct Answer: B
Rationale: Cystic fibrosis often causes infertility in males due to congenital absence of the vas deferens, making most males sterile. This reduces the likelihood of passing the disease to offspring.
