NCLEX RN Predictor Exam

1. When placing a patient in the AP position for an X-ray, what position would the patient be in?

A. Facing the X-ray film.
B. Right side against the X-ray film.
C. Left side against the X-ray film.
D. Facing away from the X-ray film

Correct answer: D

Rationale: The AP position stands for Anteroposterior Projection. When a patient is in the AP position for an X-ray, they are facing away from the X-ray film. This positioning allows for a clear view of the structures being imaged from front to back. Choices A, B, and C are incorrect because the patient is not facing or positioned against the X-ray film in the AP position, but rather facing away from it to capture the necessary diagnostic information.

2. A urine pregnancy test:

A. May be negative even if a blood pregnancy test is positive.
B. Is positive only during the first trimester of pregnancy.
C. Will be negative if the amount of LH isn't enough to meet or exceed the sensitivity of the testing device.
D. All of the above.

Correct answer: May be negative even if a blood pregnancy test is positive.

Rationale: A urine pregnancy test detects HCG in a pregnant woman's urine. Blood levels of HCG are usually higher and register earlier than HCG levels in the urine. Choice A is correct because urine pregnancy tests may be negative even if a blood pregnancy test is positive due to the differences in HCG levels in blood and urine. Choice B is incorrect because a urine pregnancy test can be positive throughout pregnancy, not just in the first trimester. Choice C is incorrect because LH (luteinizing hormone) is not the hormone detected in a pregnancy test; it is HCG (human chorionic gonadotropin). Choice D is incorrect because not all the statements provided are true.

3. When educating a client about their new prescription for warfarin, what should the nurse advise?

A. To have his white blood cell count tested once a month
B. To avoid any activities that could lead to injury
C. To avoid eating leafy green vegetables
D. Both A and B

Correct answer: To avoid any activities that could lead to injury

Rationale: The correct answer is to advise the client to avoid any activities that could lead to injury when taking warfarin. Warfarin is an anticoagulant medication that decreases blood clotting, increasing the risk of bleeding. Engaging in activities that may result in injury can lead to uncontrolled bleeding, which can be serious. While monitoring white blood cell count is not specifically related to warfarin therapy, avoiding leafy green vegetables is important due to their vitamin K content, which can interfere with warfarin's effectiveness. Therefore, the client should be educated to avoid activities that could cause injury to prevent potential bleeding complications.

4. During a general survey of a patient, which finding is considered normal?

A. Body mass index (BMI) of 20.
B. When standing, the patient’s base is narrow.
C. The patient appears older than their stated age.
D. Arm span (fingertip to fingertip) is greater than the height.

Correct answer: Body mass index (BMI) of 20.

Rationale: A body mass index (BMI) of 20 is considered normal as the range for a normal BMI is between 19-24. When standing, a patient's base should be wide for stability and proper weight distribution. An older appearance than the stated age may indicate a history of chronic illness or chronic alcoholism. In a general survey, the patient's arm span (fingertip to fingertip) should approximately equal the patient's height. An arm span greater than the height may suggest Marfan syndrome. Therefore, the correct choice is a normal BMI of 20, which falls within the healthy range. Choices B, C, and D all describe abnormal findings that may indicate underlying health conditions or syndromes.

5. The nurse suspects that a client is withholding health-related information out of fear of discovery and possible legal problems. The nurse formulates nursing diagnoses for the client carefully, being concerned about a diagnostic error resulting from which of the following?

A. Incomplete data
B. Generalizing from experience
C. Identifying with the client
D. Lack of clinical experience

Correct answer: Incomplete data

Rationale: In this scenario, the nurse is cautious about potential diagnostic errors due to incomplete data. When a client withholds information, it can lead to incomplete data, which may result in inaccurate nursing diagnoses and care planning. Therefore, the nurse's primary concern is collecting accurate data to make informed clinical decisions. Choices B, C, and D are not relevant to the situation described. Generalizing from experience, identifying with the client, and lack of clinical experience do not directly address the issue of incomplete data impacting the diagnostic process.
