NCLEX RN Exam Preview Answers
1. The healthcare provider is preparing to use an otoscope for an examination. Which statement is true regarding the otoscope?
- A. Often used to direct light into the sinuses
- B. Used to examine the structures of the internal ear
- C. Uses a short, broad speculum to help visualize the ear
- D. Directs light into the ear canal and onto the tympanic membrane
Correct answer: D
Rationale: The otoscope is a tool used to examine the ear canal and tympanic membrane, which separates the external and middle ear. It is not intended to direct light into the sinuses or examine the internal structures of the ear. The otoscope typically uses a short, narrow speculum to aid in visualizing the ear canal and tympanic membrane, not a short, broad speculum as mentioned in choice C.
2. Where is the Loop of Henle located in the body?
- A. Liver
- B. Kidney
- C. Heart
- D. Ear
Correct answer: B
Rationale: The Loop of Henle is a crucial structure found in the kidneys. It plays a vital role in the concentration of urine by creating a concentration gradient in the renal medulla. Choices A, C, and D are incorrect because the Loop of Henle is not located in the liver, heart, or ear. Understanding the anatomical location of the Loop of Henle is essential in comprehending renal physiology and the mechanism of action of diuretic medications.
3. A client is undergoing range of motion exercises, and the nurse moves the leg in a pattern of circumduction. Which movement is the nurse performing?
- A. Bending the leg at the knee
- B. Turning the foot inward and outward
- C. Moving the leg in a circle
- D. Moving the leg forward and up
Correct answer: C
Rationale: Circumduction involves moving a limb in a circular pattern. In this scenario, the nurse is performing circumduction by moving the leg in a circular motion, engaging the muscles of the gluteus maximus and gluteus medius. Choice A, 'Bending the leg at the knee,' is incorrect as it describes flexion and extension movements. Choice B, 'Turning the foot inward and outward,' refers to inversion and eversion movements of the foot, not circumduction. Choice D, 'Moving the leg forward and up,' describes flexion and abduction movements, not circumduction.
4. When considering the structural organization of the human body, what is the basic unit of life?
- A. Chemicals
- B. Atoms
- C. Molecules
- D. Cells
Correct answer: D
Rationale: The basic unit of life is the cell. Cells are considered the fundamental unit of life because they are capable of carrying out all the processes necessary for life, such as growth, reproduction, responding to stimuli, and more. While chemicals, atoms, and molecules are essential components of cells and living organisms, they are not considered the basic unit of life. Chemicals are general substances, atoms are the smallest units of matter, and molecules are combinations of atoms. Therefore, the correct answer is cells, as they are the building blocks of all living organisms.
5. The healthcare professional is preparing to auscultate the abdomen. How should they proceed?
- A. Warm the endpiece of the stethoscope by rubbing it between their hands.
- B. Ensure the patient is adequately covered and comfortable during the examination.
- C. Ensure that the diaphragm side of the stethoscope is in use.
- D. Check the room temperature and offer blankets to the patient if needed.
Correct answer: D
Rationale: When preparing to auscultate the abdomen, it is important to ensure the patient's comfort. The room should be warm to prevent shivering, which can interfere with sound clarity. Offering blankets to the patient if they feel cold helps maintain their comfort during the examination. The endpiece of the stethoscope should be warmed by rubbing it between the examiner's hands, not by placing it in warm water. It is important to use the diaphragm, not the bell, of the stethoscope to auscultate for bowel sounds. Therefore, choice D is the correct answer, as it addresses the patient's comfort and the room temperature, which are essential for a successful abdominal auscultation.
