NCLEX RN Actual Exam Test Bank

1. The Atlas and the Axis are:

A. found in the vertebrae.
B. described as being cervical.
C. the first two bones that form the column for the spine on the superior aspect.
D. All of the above.

Correct answer: D

Rationale: The Atlas and the Axis are the first two cervical vertebrae, designated as C1 and C2. The Atlas (C1) supports the skull, while the Axis (C2) allows for rotation of the skull. Therefore, all the statements in choices A, B, and C are correct, making 'All of the above' the correct answer. Choice A is correct as the Atlas and Axis are indeed found in the vertebrae. Choice B is correct as they are the first two cervical vertebrae. Choice C is correct as these bones form the superior aspect of the spine.

2. Which of the following descriptions best describes the function of the thyroid gland?

A. The thyroid gland converts glucose into glycogen
B. The thyroid gland secretes cortisol during times of stress
C. The thyroid gland regulates body metabolism
D. The thyroid gland affects skin pigmentation

Correct answer: C

Rationale: The thyroid gland is responsible for secreting thyroxine (T4) and triiodothyronine (T3), which work to regulate the metabolism of the body's cells. The primary function of the thyroid gland is to control the body's metabolic rate, affecting processes such as heart rate, temperature regulation, and energy levels. Choices A, B, and D are incorrect because the thyroid gland is not involved in converting glucose into glycogen, secreting cortisol, or affecting skin pigmentation. Instead, the primary role of the thyroid gland is to regulate the metabolism and energy balance in the body.

3. What is the purpose of MSDS sheets?

A. Contain the ordering information for each piece of equipment in the office.
B. Are required by OSHA to be accessible to all employees of the office.
C. Can be used to treat patients who have been injured in equipment accidents.
D. None of the above.

Correct answer: B

Rationale: MSDS sheets, also known as Materials Safety Data Sheets, are essential documents that provide detailed information about chemicals used in the workplace. They are required by OSHA to be easily accessible to all employees to ensure they have the necessary information to handle chemicals safely. MSDS sheets do not contain ordering information for equipment in the office (Choice A) or serve as a treatment guide for injured patients (Choice C). Therefore, the correct answer is that MSDS sheets are required by OSHA to be accessible to all employees of the office.

4. The instructor is teaching a class on basic assessment skills. Which of the following statements is true regarding the stethoscope and its use?

A. Slope of the earpieces should point forward toward the examiner's nose.
B. It blocks out extraneous room noise but does not magnify sound.
C. The tubing length should be 14 to 18 inches to prevent sound distortion.
D. Both fit and quality of the stethoscope are important.

Correct answer: B

Rationale: The stethoscope does not magnify sound but effectively blocks out extraneous room noises. The correct orientation of the earpieces is with the slope pointing forward toward the examiner's nose, not posteriorly. The tubing length of a stethoscope should ideally be between 14 to 18 inches (36 to 46 cm) to avoid sound distortion. Using tubing longer than this range can distort sound. Both the fit and quality of the stethoscope are crucial for accurate auscultation and assessment, highlighting their significance in clinical practice. Therefore, the correct answer is that the stethoscope blocks out extraneous room noise but does not magnify sound.

5. A client is being assisted to lie in the Sims' position. In what position does the nurse arrange the client?

A. The client lies on his side with the upper leg flexed
B. The client lies on his back with his head lower than his feet
C. The client lies on his abdomen with a pillow supporting his head
D. The client is sitting up at a 90-degree angle

Correct answer: A

Rationale: The Sims' position is a side-lying position used for examinations or comfort. In the Sims' position, the client lies on their side with the upper leg flexed. The abdomen is slightly downward, and the lower arm is positioned behind the body. A pillow can be used to support the leg. Choice B is incorrect as it describes a position with the client lying on their back with the head lower than the feet. Choice C is incorrect as it describes a prone position, not the Sims' position. Choice D is incorrect as it describes a sitting position, not the Sims' position.
