Mock NCLEX RN Exam Questions
Extract:
Question 1 of 5
A client develops an intestinal obstruction postoperatively. A nasogastric tube is attached to low, intermittent suction with orders to 'Irrigate NG tube with sterile saline q1h and prn.' The rationale for using sterile saline, as opposed to using sterile water to irrigate the NG tube is:
Correct Answer: A
Rationale: Water is a hypotonic solution and will deplete electrolytes and cause metabolic acidosis when used for nasogastric irrigation. Irrigating with saline does not cause abdominal discomfort. Severe, colicky abdominal pain is a symptom of intestinal obstruction. Irrigating with water will not cause restlessness or insomnia in the postoperative client. Restlessness and insomnia can be emotional complications of surgery. A nasogastric tube placed in the stomach is used to decompress the bowel. Irrigating with saline ensures a patent, well-functioning tube. Irrigating with saline will not increase peristalsis.
Question 2 of 5
A physician tells the nurse that he wants to orally intubate a client with a No. 8 endotracheal tube. The finding of normal breath sounds on the right side of the chest and diminished, distant breath sounds on the left side of the chest of a newly intubated client is probably due to:
Correct Answer: C
Rationale: The right mainstem bronchus is most frequently intubated in error because the angle of the right mainstem bronchus is very small as compared with that of the left mainstem bronchus. Because ventilation is only occurring on the right side, the nurse would auscultate diminished and distant breath sounds on the left.
Question 3 of 5
Which of the following describes the language development of a two-year-old?
Correct Answer: C
Rationale: A two-year-old typically can combine three or four words to form simple sentences (e.g., 'Me want milk'). They understand basic concepts like 'yes' and 'no,' but not all words. Repeatedly asking 'why?' is more common in older preschoolers.
Question 4 of 5
The nurse is caring for a client with a history of anaphylaxis to peanuts. Which precaution is most important?
Correct Answer: A
Rationale: An epinephrine auto-injector is critical for immediate treatment of anaphylaxis, a life-threatening allergic reaction. Private rooms, antihistamines, and monitoring are secondary to ensuring rapid emergency response.
Question 5 of 5
The obstetric client's fetal heart rate is 80-90 during the contractions. The first action the nurse should take is:
Correct Answer: B
Rationale: A fetal heart rate of 80-90 during contractions indicates bradycardia possibly from cord compression or uteroplacental insufficiency. Turning the client to her left side improves placental perfusion and is the first action.
