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. When percussing over the abdomen of an obese patient, the nurse is unable to identify any changes in sound. What would the nurse do next?
- A. Ask the patient to take deep breaths to relax the abdominal musculature.
- B. Consider this finding as normal and proceed with the abdominal assessment.
- C. Increase the amount of strength used when attempting to percuss over the abdomen.
- D. Decrease the amount of strength used when attempting to percuss over the abdomen.
Correct answer: C
Rationale: When percussing an obese patient's abdomen, the thickness of their body wall can affect the sound produced. A stronger percussion stroke is needed for obese or very muscular patients. The force of the blow determines the loudness of the note. Asking the patient to take deep breaths, considering the finding as normal, or decreasing the strength used are not appropriate actions in this scenario.
3. What is the minimum amount of personal protective equipment for a nurse when working with a newborn immediately after a high-risk delivery in a client's room?
- A. Sterile gown, gloves
- B. Mask, gown, shoe covers
- C. Gloves
- D. Hat, mask, gloves, gown, shoe covers
Correct answer: C
Rationale: The correct answer is gloves. When attending a high-risk delivery and handling a newborn immediately after birth, the minimum personal protective equipment required for a nurse includes gloves. This is essential to protect the nurse from potential exposure to the mother's blood or body fluids that may be present on the newborn's skin. Choices A, B, and D include additional protective equipment that is not necessary for this specific scenario. Wearing gloves is crucial for infection control and to prevent the transmission of pathogens.
4. The nurse informs the physical therapy department that the client is too weak to use a walker and needs to be transported by wheelchair. Which step of the nursing process is the nurse engaged in at this time?
- A. Assessment
- B. Planning
- C. Implementation
- D. Evaluation
Correct answer: C
Rationale: The nurse is responsible for coordinating the plan of care with other disciplines to ensure the client's safety. This action represents the implementation phase of the nursing process. During the implementation phase, the nurse puts the care plan into action, which includes coordinating with other healthcare team members like the physical therapy department. Assessment involves data gathering, planning involves goal setting, and evaluation involves determining the attainment of client goals.
5. What type of blood pressure measurement error is most likely to occur if the nurse does not check for the presence of an auscultatory gap?
- A. Diastolic blood pressure may not be heard.
- B. Diastolic blood pressure may be falsely low.
- C. Systolic blood pressure may be falsely low.
- D. Systolic blood pressure may be falsely high.
Correct answer: C
Rationale: If an auscultatory gap is undetected, a falsely low systolic reading may occur. This gap can lead to an underestimation of the systolic blood pressure, causing potential misinterpretation of the patient's condition. The diastolic blood pressure may not be heard due to the gap, but the critical issue in this scenario is the risk of underestimating systolic blood pressure, which can impact clinical decision-making. Choices B, C, and D are incorrect because the key concern in this context is the potential for a falsely low systolic blood pressure reading when an auscultatory gap is not assessed.
