NCLEX-RN Exam Practice Questions
Extract:
Question 1 of 5
A client with a history of asthma is admitted with an acute exacerbation. The nurse should give priority to:
Correct Answer: A
Rationale: Bronchodilators are the first-line treatment for an acute asthma exacerbation to relieve bronchospasm and improve airflow.
Question 2 of 5
The nurse is assessing a client with suspected hypovolemic shock. Which finding is most indicative?
Correct Answer: A
Rationale: Tachycardia is a hallmark of hypovolemic shock, compensating for reduced blood volume. Hypothermia (
B) is secondary, bradypnea (
C) is atypical, and hypertension (
D) is not associated.
Question 3 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 4 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.

Correct Answer: B
Rationale: Respiratory acidosis is determined by low pH and elevated PaCO2.
