NCLEX-RN Exam Practice Questions
Extract:
Question 1 of 5
The nurse is caring for a client with a history of Rh sensitization. The physician orders a Kleihauer-Betke test. The purpose of this test is to:
Correct Answer: A
Rationale: The Kleihauer-Betke test quantifies fetal blood in maternal circulation critical in Rh sensitization to determine the dose of RhoGAM needed to prevent maternal antibody formation. It does not assess lung maturity antibodies or amniotic fluid volume.
Question 2 of 5
A 20-year-old female has a prescription for Sumycin (tetracycline). While teaching the client how to take her medicine, the nurse learns that the client is also taking an oral contraceptive. Which instruction should be included in the teaching plan?
Correct Answer: D
Rationale: Tetracyclines can reduce the effectiveness of oral contraceptives by altering gut flora, affecting estrogen metabolism. This increases the risk of unintended pregnancy, requiring backup contraception.
Question 3 of 5
A woman diagnosed with multiple sclerosis is disturbed with diplopia. The nurse will teach her to:
Correct Answer: D
Rationale: Limiting activities requiring close vision will not alleviate the discomfort of double vision. Frequent naps may be comforting, but they will not prevent double vision. Artificial tears are necessary in the absence of a corneal reflex, but they have no effect on diplopia. An eye patch over either eye will eliminate the effects of double vision during the time the eye patch is worn. An eye patch is safe for a person with an intact corneal reflex.
Question 4 of 5
The nurse is caring for a patient with suspected diverticulitis. The nurse would be most prudent in questioning an order for which of the following diagnostic tests?
Correct Answer: B
Rationale: A barium enema is contraindicated in suspected diverticulitis due to the risk of perforation and peritonitis. Ultrasound, CT scans, and CBC are appropriate for diagnosing diverticulitis or assessing complications.
Question 5 of 5
What is the most effective method to identify early breast cancer lumps?
Correct Answer: D
Rationale: Mammograms are less effective than breast self-examination for the diagnosis of abnormalities in younger women, who have denser breast tissue. They are more effective for women older than 40. Up to 15% of early-stage breast cancers are detected by physical examination; however, 95% are detected by women doing breast self-examination. Ultrasound is used primarily to determine the location of cysts and to distinguish cysts from solid masses. Monthly breast self-examination has been shown to be the most effective method for early detection of breast cancer. Approximately 95% of lumps are detected by women themselves.
