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. The Sinoatrial Node (SA) is located within which of the following heart structures?
- A. Mitral Valve
- B. Right Ventricle
- C. Right Atrium
- D. Left Atrium
Correct answer: C
Rationale: The Sinoatrial (SA) Node, often called the heart's natural pacemaker, is situated within the upper wall of the Right Atrium. It initiates the electrical impulses that regulate the heartbeat. Choices A, B, and D are incorrect because the SA node is not located in the Mitral Valve, Right Ventricle, or Left Atrium. It is specifically positioned in the Right Atrium to coordinate the heart's rhythm and timing.
3. 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.
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 healthcare provider is reviewing theories of illness. The germ theory, which states that microscopic organisms such as bacteria and viruses are responsible for specific disease conditions, is a basic belief of which theory of illness?
- A. Holistic
- B. Biomedical
- C. Naturalistic
- D. Magicoreligious
Correct answer: B
Rationale: The correct answer is B: Biomedical. Among the biomedical explanations for disease is the germ theory, which states that microscopic organisms such as bacteria and viruses are responsible for specific disease conditions. The naturalistic or holistic perspective holds that the forces of nature must be kept in natural balance. The magicoreligious perspective holds that supernatural forces dominate and cause illness or health. Therefore, options A, C, and D are incorrect as they do not align with the germ theory explanation provided in the question.
