NCLEX RN Predictor Exam Questions
Extract:
Question 1 of 5
Parents should be taught not to prop the bottle when feeding their infants. In addition to the risk of choking, it puts the infant at risk for:
Correct Answer: A
Rationale: Because the eustachian tube is short and straight in the infant, formula that pools in the back of the throat attacks bacteria which can enter the middle ear and cause an infection. Asthma is not associated with propping the bottle. Conjunctivitis is an eye infection and not associated with propping the bottle.
Tonsillitis is usually a result of pharyngitis and not propping the bottle.
Question 2 of 5
Which of the following ECG changes would be seen as a positive myocardial stress test response?
Correct Answer: C
Rationale: Hyperacute T waves occur with hyperkalemia. Prolongation of the PR interval occurs with first-degree AV block. Horizontal ST-segment depression of >1 mm during exercise is definitely a positive criterion on the exercise ECG test. Pathological Q waves occur with MI.
Question 3 of 5
A pregnant client is having a nonstress test (NST). It is noted that the fetal heart beat rises 20 bpm, lasting 20 seconds, every time the fetus moves. The nurse explains that:
Correct Answer: C
Rationale: The test results were normal, so there would be no need to repeat to determine results. There are no data to indicate further tests are needed, because the result of the NST was normal. An NST is reported as reactive if there are two to three increases in the fetal heart rate of 15 bpm, lasting at least 15 seconds during a 15-minute period. The NST results were normal, so there was no fetal distress.
Question 4 of 5
The nurse is teaching a client with a history of hypertension about dietary modifications. The nurse should tell the client to avoid:
Correct Answer: C
Rationale: Processed foods are high in sodium, which can exacerbate hypertension by increasing blood volume, so they should be avoided.
Question 5 of 5
The nurse is assessing a client with suspected Cushing’s syndrome. Which finding is most consistent with this diagnosis?
Correct Answer: B
Rationale: Cushing’s syndrome causes cortisol excess, leading to a moon-shaped face due to fat redistribution. Weight gain, hypertension, and tachycardia are more common than weight loss, hypotension, or bradycardia.
