NCLEX RN Exam Preview Answers
1. The nurse is reviewing percussion techniques with a new graduate nurse. Which action performed by the graduate nurse while percussing requires the nurse to intervene?
- A. Percussing twice over each area
- B. Striking with the fingertip, not the finger pad
- C. Using the wrist to make the strikes, not the arm
- D. Quickly lifting the striking finger after each stroke
Correct answer: A
Rationale: The correct answer is to percuss twice over each area, not once. This technique helps ensure a more accurate assessment. Striking with the fingertip instead of the finger pad is correct because the tip of the finger produces clearer sounds. Using the wrist to make the strikes instead of the arm is appropriate as it allows for more controlled and precise percussion. Quickly lifting the striking finger after each stroke is also correct to prevent damping off vibrations. Therefore, percussing once over each area (Choice A) is incorrect as it does not follow the standard percussion technique.
2. When percussing over the lungs of a 4-year-old child, the nurse hears bilateral loud, long, and low tones. How should the nurse proceed?
- A. Palpate over the area for increased pain and tenderness.
- B. Ask the child to take shallow breaths and percuss over the area again.
- C. Refer the child to a specialist because of an increased amount of air in the lungs.
- D. Consider this finding as normal for a child this age and proceed with the examination.
Correct answer: D
Rationale: In pediatric patients, loud, long, and low tones heard when percussing over the lungs are normal findings. These percussion notes are characteristic of a child's lung due to its thin chest wall and increased air content. It is unnecessary to palpate for pain and tenderness, ask the child to take shallow breaths and repeat the percussion, or refer the child to a specialist. Therefore, the correct action is to consider these findings as normal for the child's age and continue with the examination.
3. When assessing the pulse of a 6-year-old patient, the nurse notices that the heart rate varies with the respiratory cycle, speeding up at the peak of inspiration and slowing to normal with expiration. What action would the nurse take next?
- A. Notify the physician.
- B. Record this finding as normal.
- C. Check the child's blood pressure and note any variation with respiration.
- D. Document that this child has bradycardia and continue with the assessment.
Correct answer: B
Rationale: The correct action for the nurse to take next is to record this finding as normal. Sinus dysrhythmia, characterized by heart rate variation with the respiratory cycle, is commonly found in children and young adults. The heart rate speeds up at the peak of inspiration and slows to normal with expiration. This phenomenon is a normal variant and does not require any intervention. There is no need to notify the physician as this finding is within the expected range for this age group. Checking the child's blood pressure for variations with respiration or documenting the child as having bradycardia would not be appropriate in this case, as sinus dysrhythmia is a normal physiological response.
4. Which of the following statements best describes substance P?
- A. Substance P decreases a client's sensitivity to pain
- B. Substance P levels are drawn before administration of narcotic analgesics
- C. Substance P is found in the brain and is responsible for pain control and management of depression
- D. Substance P is found in the dorsal horn of the spinal column
Correct answer: D
Rationale: Substance P is a neurotransmitter found in the brain and the dorsal horn of the spinal column, not just in the brain. It is associated with pain transmission and modulation. Substance P is known to cause inflammation, edema, and pain. While it plays a role in pain perception, it does not decrease a client's sensitivity to pain (Choice A), nor are its levels typically drawn before administering narcotic analgesics (Choice B). Although substance P is involved in pain control, it is not responsible for managing depression (Choice C). Therefore, the correct statement is that substance P is found in the dorsal horn of the spinal column.
5. The Sims' position is MOST similar to the ________ position.
- A. prone
- B. lateral
- C. supine
- D. Fowler's
Correct answer: B
Rationale: The correct answer is 'lateral.' The Sims' position is characterized by the patient lying on their side with the upper knee flexed and the upper arm positioned in front of the body. This is similar to the lateral position where the patient is also lying on their side. The prone position (choice A) is when the patient lies face down, the supine position (choice C) is when the patient lies face up, and Fowler's position (choice D) is a seated position with the head of the bed elevated at a 45-90 degree angle. Therefore, the lateral position is the most similar to the Sims' position as both involve the patient lying on their side.
