NCLEX RN Exam Preview Answers
1. When is the best time for the nurse to attempt to elicit the Moro reflex during an infant examination?
- A. When the infant is sleeping
- B. At the end of the examination
- C. Before auscultation of the thorax
- D. At about the middle of the examination
Correct answer: B
Rationale: The Moro reflex, also known as the startle reflex, is best elicited at the end of the examination because it can cause the infant to cry. This reflex is triggered by a sudden change in position or loud noise, and it involves the infant's arms extending and then coming back together as if embracing. By eliciting this reflex at the end of the examination, the nurse can observe the infant's response and ensure that the examination is completed without unnecessary distress. Choices A, C, and D are incorrect because the Moro reflex is typically elicited at the end of the examination to avoid disrupting the assessment process and causing unnecessary discomfort to the infant.
2. The healthcare professional is preparing to use a stethoscope for auscultation. Which statement is true regarding the diaphragm of the stethoscope?
- A. Used to listen for high-pitched sounds
- B. Used to listen for low-pitched sounds
- C. Should be firmly held against the person's skin to block out low-pitched sounds
- D. Should be lightly held against the person's skin to listen for extra heart sounds and murmurs
Correct answer: A
Rationale: The diaphragm of the stethoscope is designed for listening to high-pitched sounds like breath, bowel, and normal heart sounds. It should be firmly held against the person's skin to ensure optimal sound transmission, leaving a ring after use. On the other hand, the bell of the stethoscope is ideal for detecting soft, low-pitched sounds such as extra heart sounds or murmurs. Therefore, the diaphragm is not used to block out low-pitched sounds but rather to enhance the detection of high-frequency sounds.
3. Which of these guidelines would a healthcare professional follow when measuring a patient's weight?
- A. The patient is always weighed wearing only undergarments.
- B. The type of scale matters and should be consistent day to day.
- C. The patient should remove heavy outer clothing, shoes, and jackets before weighing.
- D. Attempts should be made to weigh the patient at approximately the same time of day if a sequence of weights is necessary.
Correct answer: D
Rationale: When measuring a patient's weight, it is important to ensure accuracy and consistency. If a sequence of repeated weights is necessary, the healthcare professional should attempt to weigh the patient at the same time of day and with the same types of clothing worn each time. It is crucial to use a standardized balance or electronic standing scale for accurate weight measurement. Choice A is incorrect as patients should remove heavy outer clothing, shoes, and jackets before being weighed for accurate results. Choice B is incorrect because the type of scale used does matter and should be consistent for reliable weight tracking. Choice C is incorrect as patients should not leave on heavy outer clothing, shoes, or jackets as these items can add to the weight recorded inaccurately.
4. During a class on religion and spirituality, the nurse is asked to define spirituality. Which statement by the nurse best describes spirituality?
- A. "Is a personal search to discover a supreme being."?
- B. "Is an organized system of beliefs concerning the cause, nature, and purpose of the universe."?
- C. "Is a belief that each person exists forever in some form, such as a belief in reincarnation or the afterlife."?
- D. "Focuses on a connection with something bigger than oneself and a belief in transcendence."?
Correct answer: D
Rationale: Spirituality is a broad term that focuses on a connection with something greater than oneself and a belief in transcendence. It is a personal journey that arises from unique life experiences and the individual's quest to find purpose and meaning in life. The correct answer emphasizes the essence of spirituality, which involves seeking a connection with a higher power and believing in transcendence. Choices A, B, and C, on the other hand, define aspects of religion rather than spirituality. Choice A refers to a personal search for a supreme being, which is more aligned with religious beliefs. Choice B describes an organized system of beliefs about the universe, typically associated with religion. Choice C pertains to beliefs about existence after death, such as reincarnation or the afterlife, which are often religious concepts. Therefore, the best description of spirituality is focusing on a connection with something beyond oneself and a belief in transcendence.
5. For a patient who is blood type AB, which blood product can they receive?
- A. Plasma from a type B donor
- B. Whole blood from a type A donor
- C. Packed RBCs from a type O donor
- D. All of the above
Correct answer: C
Rationale: A patient with blood type AB has AB antigens on their red blood cells. This means they can only receive blood products that are compatible with these antigens. Choice A is incorrect because an AB patient cannot receive plasma from a type B donor due to the antibodies present in type B plasma. Choice B is incorrect because an AB patient cannot receive whole blood from a type A donor as it contains incompatible antigens. Choice C is the correct answer because an AB patient can receive packed RBCs from a type O donor. Type O donors have no A or B antigens, making their blood compatible for transfusion to recipients with any blood type. Therefore, choices A and B are incorrect, and the correct choice is C.
