NCLEX RN Exam Preview Answers
1. The nurse is comparing the concepts of religion and spirituality. Which statement describes an appropriate component of one's spirituality?
- A. Belief in and worship of God or gods
- B. Being closely tied to one's ethnic background
- C. Attendance at a specific church or place of worship
- D. A connection with something larger than oneself and belief in transcendence
Correct answer: D
Rationale: Spirituality refers to a connection with something larger than oneself and a belief in transcendence. The other responses do not apply to spirituality. Choice A, 'Belief in and worship of God or gods,' and choice C, 'Attendance at a specific church or place of worship,' are more aligned with religious practices. Choice B, 'Being closely tied to one's ethnic background,' is not a defining aspect of spirituality or religion as it pertains more to cultural identity rather than spiritual beliefs.
2. During an examination, the nurse notices that a female patient has a round "moon"? face, central trunk obesity, and a cervical hump. Her skin is fragile with bruises. The nurse determines that the patient likely has which condition?
- A. Gigantism
- B. Acromegaly
- C. Cushing syndrome
- D. Marfan syndrome
Correct answer: C
Rationale: Cushing syndrome is characterized by weight gain and edema with central trunk and cervical obesity (buffalo hump) and a round, plethoric face (moon face). Excessive catabolism in Cushing syndrome causes muscle wasting, weakness, thin arms and legs, reduced height, and thin, fragile skin with purple abdominal striae, bruising, and acne. Gigantism is characterized by increased height and weight and delayed sexual development, which are not present in the patient. Acromegaly results from excessive growth hormone secretion in adulthood, leading to bone overgrowth in specific areas like the face, head, hands, and feet. Marfan syndrome is an inherited connective tissue disorder characterized by a tall, thin stature and distinct features not seen in this patient. The combination of signs described in the question aligns with the clinical presentation of Cushing syndrome.
3. To properly read a meniscus,
- A. hold the measuring device at eye level and read the bottom of the curve of the liquid level
- B. hold the measuring device at eye level and read the top of the curve of the liquid level where the liquid adheres to the walls of the container.
- C. hold the measuring device at table level and, looking down into the measuring device, read the bottom of the curve of the liquid level.
- D. hold the measuring device at table level and, looking down into the measuring device, read the top of the curve of the liquid level.
Correct answer: A
Rationale: To properly read a meniscus, it is essential to hold the measuring device at eye level to avoid parallax error. Reading the bottom of the curve of the liquid level is correct because the meniscus is the concave or convex curve at the liquid's surface. Choice B is incorrect because reading the top of the curve where the liquid adheres to the walls of the container can lead to inaccurate measurements. Choices C and D are incorrect as they suggest holding the device at table level, which can introduce parallax error and result in an incorrect reading.
4. Which brain structure serves as the heat-regulating center?
- A. Hypothalamus
- B. Pituitary Gland
- C. Pons
- D. Medulla Oblongata
Correct answer: A
Rationale: The correct answer is the Hypothalamus. The hypothalamus is responsible for regulating body temperature, ensuring it stays within a narrow range. Moreover, the hypothalamus controls various essential bodily functions, such as hunger, thirst, and circadian rhythms. Choices B, C, and D are incorrect because the Pituitary Gland primarily produces and releases hormones, the Pons is involved in functions like sleep, respiration, and bladder control, and the Medulla Oblongata controls vital functions like breathing and heart rate, but not body temperature regulation.
5. When checking for proper blood pressure cuff size, which guideline is correct?
- A. The standard cuff size is appropriate for all sizes.
- B. The length of the rubber bladder should equal 80% of the arm circumference.
- C. The width of the rubber bladder should equal 80% of the arm circumference.
- D. The width of the rubber bladder should equal 40% of the arm circumference.
Correct answer: D
Rationale: When selecting the correct blood pressure cuff size, it is essential to ensure that the width of the rubber bladder equals 40% of the circumference of the person's arm. This ensures proper fitting and accurate readings. The length of the bladder should actually equal 80% of the arm circumference, not 80% of the width, making choices B and C incorrect. Choice A stating that the standard cuff size is appropriate for all sizes is inaccurate, as using an incorrectly sized cuff can lead to inaccurate blood pressure readings.
