NCLEX RN Exam Preview Answers
1. When examining an infant, which area should the nurse examine first?
- A. Ear
- B. Nose
- C. Throat
- D. Abdomen
Correct answer: D
Rationale: When examining an infant, the nurse should start by examining the least-distressing areas first before moving on to more invasive areas. The abdomen is typically the least distressing area to examine, so it should be assessed first. Examining the eye, ear, nose, and throat are considered more invasive and should be saved for last. Therefore, the correct choice is to examine the abdomen first to ensure a comfortable and less distressing examination process for the infant. Choices A, B, and C (Ear, Nose, Throat) are more invasive areas and should be examined after the abdomen.
2. The mitral valve is synonymous with the term:
- A. Left ventricle
- B. Right atrium
- C. Bicuspid valve
- D. Tricuspid valve
Correct answer: C
Rationale: The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle, regulating blood flow from the left atrium into the left ventricle. The term 'bicuspid' refers to the valve's two cusps or leaflets. This distinguishes it from the tricuspid valve (Choice D), which has three cusps, making Choice D incorrect. The left ventricle (Choice A) and right atrium (Choice B) are not synonymous with the mitral valve. Therefore, the correct answer is C: Bicuspid valve.
3. An older adult patient brought to the emergency department by a family member is wandering outside, saying, "I can't find my way home."? The patient is confused and unable to answer questions. What is the nurse's best action?
- A. Document the patient's mental status and obtain other assessment data from the family member.
- B. Record the patient's answers to questions on the nursing assessment form.
- C. Ask an advanced practice nurse to perform the assessment interview.
- D. Call for a mental health advocate to maintain the patient's rights.
Correct answer: A
Rationale: In this scenario, the patient is confused and unable to answer questions. When the patient is unable to provide information, it is important to use secondary sources such as family members. The nurse's best action is to document the patient's mental status and obtain additional assessment data from the family member. This approach will help gather relevant information about the patient's condition. Asking an advanced practice nurse to perform the assessment interview is not necessary as it is within the staff nurse's scope of practice. Calling for a mental health advocate is also unnecessary at this point as the priority is to assess the patient's condition and gather information from the family member.
4. Which complication of cardiac catheterization should the nurse monitor for in the initial 24 hours after the procedure?
- A. Angina at rest
- B. Thrombus formation
- C. Dizziness
- D. Falling blood pressure
Correct answer: B
Rationale: Thrombus formation is a critical complication of cardiac catheterization that the nurse should monitor for in the initial 24 hours after the procedure. A thrombus can form in the blood vessels, obstructing blood flow and potentially leading to serious consequences such as embolism or organ ischemia. While angina at rest, dizziness, and falling blood pressure are potential complications following cardiac catheterization, they are not typically associated with the immediate post-procedural period. Monitoring for thrombus formation is essential to ensure early detection and intervention, which can prevent serious complications.
5. The nurse is conducting a health fair for older adults. Which statement is true regarding vital sign measurements in aging adults?
- A. The pulse is easier to palpate due to the rigidity of the blood vessels.
- B. An increased respiratory rate and a shallower inspiratory phase are expected findings.
- C. A widened pulse pressure occurs from changes in the systolic and diastolic blood pressures.
- D. Changes in the body's temperature regulatory mechanism decrease the older adult's likelihood of developing a fever.
Correct answer: B
Rationale: Aging causes a decrease in vital capacity and decreased inspiratory reserve volume. As a result, the examiner may observe a shallower inspiratory phase and an increased respiratory rate in older adults. Contrary to common belief, the increased rigidity of arterial walls actually makes the pulse easier to palpate in aging adults. Pulse pressure is widened, not decreased, due to changes in systolic and diastolic blood pressures. Furthermore, changes in the body's temperature regulatory mechanism make older individuals less likely to develop a fever but more susceptible to hypothermia.
