NCLEX RN Exam Preview Answers Questions
Question 1 of 5
Which of the following descriptions best describes the function of the thyroid gland?
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.
Question 2 of 5
When preparing to perform a physical examination on an infant, what should the nurse do?
Correct Answer: A
Rationale: For performing a physical examination on an infant, it is important to have the parent remove all clothing except the diaper to allow for a thorough examination while ensuring the infant remains comfortable. It is recommended not to feed the infant immediately before the examination but rather 1 to 2 hours after feeding when the baby is neither too drowsy nor too hungry. While a pacifier may be used during invasive assessments or if the infant is crying, it is not typically necessary during abdominal auscultation. Having the parent present during the examination is important for the infant's security and for the parent to understand the process; however, the clothing should still be removed except for the diaper to facilitate a comprehensive assessment.
Question 3 of 5
A 6-month-old infant has been brought to the well-child clinic for a checkup. The infant is currently sleeping. What would the nurse do first when beginning the examination?
Correct Answer: C
Rationale: When the infant is quiet or sleeping, it is an ideal time to assess the cardiac, respiratory, and abdominal systems. It is recommended not to wake the infant unnecessarily. Auscultating the lungs and heart while the infant is still sleeping allows for a comprehensive assessment without disturbing the infant. Examining the infant's hips prematurely may disrupt the infant's sleep. Starting with an assessment of the eye is not appropriate as it is an invasive procedure and should be performed towards the end of the examination after the non-invasive assessments have been completed.
Question 4 of 5
A 2-year-old child has been brought to the clinic for a well-child checkup. What is the best way for the nurse to begin the assessment?
Correct Answer: C
Rationale: The best place to examine the toddler is on the parent's lap. Toddlers understand symbols; therefore, a security object is helpful. Initially, the focus is more on the parent, which allows the child to adjust gradually and to become familiar with you. A 2-year-old child does not like to take off his or her clothes. Therefore, ask the parent to undress one body part at a time.
Question 5 of 5
The nurse is examining a 2-year-old child and asks, "May I listen to your heart now?"? Which critique of the nurse's technique is most accurate?
Correct Answer: D
Rationale: Children at the age of 2 often like to assert their independence by saying "No."? In situations where there is actually no choice available, offering a false choice can lead to a lack of trust. It is important not to offer a choice when there isn't one, as doing so may undermine trust. While asking for permission can enhance autonomy and trust, offering a limited option like, "Shall I listen to your heart next or your tummy?"? may be a better approach. Therefore, the correct critique of the nurse's technique in this scenario is that children at this age tend to say "No,"? so the examiner should avoid offering a choice when there isn't a real alternative.
