NCLEX RN Exam Preview Answers
1. When performing a physical assessment, what technique should the nurse always perform first?
- A. Palpation
- B. Inspection
- C. Percussion
- D. Auscultation
Correct answer: B
Rationale: During a physical assessment, the nurse should always begin with inspection. The sequence of techniques for physical examination is inspection, palpation, percussion, and auscultation. These skills are performed in a specific order, except for the abdominal assessment where auscultation precedes palpation and percussion. Inspection allows the nurse to observe and gather initial information without direct contact. It is a crucial step that provides valuable insights before proceeding to palpation, percussion, and auscultation. Therefore, choice B, 'Inspection,' is the correct answer. Choices A, C, and D are incorrect because they should follow inspection in the sequence of a comprehensive physical assessment.
2. When performing an EKG, the patient starts to laugh out of feelings of anxiety. What would you expect the EKG to show? (Choose the BEST answer.)
- A. Increased pulse rate, normal EKG
- B. Decreased pulse rate, abnormal EKG
- C. Tachycardia, poor EKG graph
- D. Bradycardia, poor EKG graph
Correct answer: C
Rationale: When a patient laughs due to anxiety during an EKG, it is likely to cause tachycardia, which is a rapid heart rate. This increased heart rate can lead to poor EKG graph quality as the electrical signals from large moving muscles can interfere with data collection from the chest leads. Therefore, in this scenario, the EKG is expected to show tachycardia with poor graph quality. Choices A, B, and D are incorrect because a patient laughing out of anxiety is more likely to result in an increased pulse rate (tachycardia) rather than a decreased pulse rate (bradycardia) or a normal EKG.
3. You have been assigned to take an apical pulse for one of the patients on the nursing unit. How will you do this?
- A. You will place the stethoscope over the heart and listen for any irregular beats.
- B. You will place the stethoscope over the heart and count the beats per minute.
- C. You will place your fingertip over the patient's wrist and feel for any irregular beats.
- D. You will place your fingertip over the patient's wrist and count the beats per minute.
Correct answer: B
Rationale: To take an apical pulse accurately, you should place the stethoscope over the heart and count the number of beats per minute. This method provides a precise assessment of the heart rate. While listening for irregular beats is essential for assessing the heart's rhythm, the primary objective of taking an apical pulse is to determine the heart rate. Choices C and D are incorrect because the apical pulse is not taken at the wrist; instead, it is obtained by auscultating at the apex of the heart, usually at the point where the fifth intercostal space meets the midclavicular line.
4. What is the primary route of transmission of MRSA?
- A. Shared needles
- B. Hands of healthcare workers
- C. Items in the healthcare environment
- D. Blood transfusions
Correct answer: B
Rationale: The correct answer is 'Hands of healthcare workers.' MRSA is primarily transmitted via the unwashed hands of healthcare workers who can carry the Staphylococcus aureus bacterium from one patient to another. Shared needles, items in the healthcare environment, and blood transfusions are not the main routes of transmission for MRSA. Shared needles can transmit bloodborne pathogens, items in the healthcare environment can harbor bacteria but are not the primary mode for MRSA, and blood transfusions are not a common route for MRSA transmission.
5. A patient is seen in the clinic for reports of "fainting episodes that started last week."? How would the nurse proceed with the examination?
- A. Blood pressure readings are taken in both arms and thighs.
- B. The patient is assisted to a lying position, and their blood pressure is taken.
- C. The patient's blood pressure is recorded in lying, sitting, and standing positions.
- D. The patient's blood pressure is recorded in lying and sitting positions; these numbers are then averaged to obtain a mean blood pressure.
Correct answer: C
Rationale: When a patient reports fainting episodes, it is crucial to assess for orthostatic hypotension. If the nurse suspects volume depletion, the patient has hypertension, is on antihypertensive medications, or has a history of fainting or syncope, blood pressure readings should be taken in three positions: lying, sitting, and standing. This assessment helps detect orthostatic hypotension, which can provide valuable information about the patient's condition. Taking blood pressure readings in multiple positions allows for a comprehensive evaluation of possible postural changes in blood pressure. Choices A, B, and D are incorrect because they do not cover the necessary positions to assess for orthostatic hypotension effectively.
