Exam Cram NCLEX RN Practice Questions

1. Which technique is correct when assessing the radial pulse of a patient?

A. Palpate for 1 minute if the rhythm is irregular.
B. Palpate for 15 seconds and multiply by 4 if the rhythm is regular.
C. Palpate for 2 full minutes to detect any variation in amplitude.
D. Palpate for 10 seconds and multiply by 6 if the rhythm is regular and the patient has no history of cardiac abnormalities.

Correct answer: A

Rationale: When assessing the radial pulse, if the rhythm is irregular, the pulse should be counted for a full minute to get an accurate representation of the pulse rate. In cases where the rhythm is regular, the recommended technique is to palpate for 15 seconds and then multiply by 4 to calculate the beats per minute. This method is more accurate and efficient for normal or rapid heart rates. Palpating for 30 seconds and multiplying by 2 is not as effective, as any error in counting results in a larger discrepancy in the calculated heart rate. Palpating for 2 full minutes is excessive and not necessary for routine pulse assessment. Palpating for 10 seconds and multiplying by 6 is not a standard technique and may lead to inaccuracies, especially in patients with cardiac abnormalities.

2. What is the proper personal protective equipment necessary for collecting a sputum specimen?

A. Gloves and face mask
B. Level Three Biocontainment uniforms
C. Eye protection and shoe covers
D. Splash shield and face mask

Correct answer: A

Rationale: When collecting a sputum specimen, it is crucial to protect against potential airborne droplets that may spread disease. The best personal protective equipment for this task includes gloves and a face mask. Gloves help prevent the spread of contaminants through hand contact, while a face mask protects the respiratory tract from inhaling infectious agents. Choice B, Level Three Biocontainment uniforms, is excessive and unnecessary for routine sputum specimen collection. Choice C, eye protection and shoe covers, does not address the specific risks associated with sputum collection. Choice D, splash shield and face mask, provides additional protection that is not typically required for sputum specimen collection, making it less appropriate than gloves and a face mask.

3. Rales and rhonchi are frequently noted during an examination of lung sounds. What is the difference between the two?

A. Rales are louder.
B. Rhonchi are noted only in infants.
C. Rales occur on inspiration, rhonchi on expiration.
D. Rales are noted only in infants.

Correct answer: C

Rationale: The correct answer is that rales occur on inspiration, while rhonchi occur on expiration. Rales are typically heard during inhalation when there is fluid in the alveoli or air passages. Rhonchi, on the other hand, are caused by air passing through obstructed airways during exhalation due to secretions in the respiratory tract. Choice A is incorrect because the loudness of the sounds is not the primary distinguishing factor between rales and rhonchi. Choice B is incorrect as rhonchi can be heard in individuals beyond infancy. Choice D is incorrect as rales can be present in patients of various age groups, not just infants.

4. What action by the nurse is appropriate when examining a 16-year-old male teenager?

A. Discuss health teaching with the teenager to promote wellness.
B. Ask the parent to step out of the room during the history and physical examination to respect the teenager's privacy.
C. Use age-appropriate communication when speaking to the teenager to ensure understanding.
D. Provide feedback that his body is developing normally and discuss the wide variation among teenagers on the rate of growth and development.

Correct answer: D

Rationale: During the examination of a 16-year-old male teenager, it is essential to provide feedback that his body is developing normally and to discuss the wide variation among teenagers regarding growth and development. This reassures the teenager about his health status and addresses any concerns about physical development. It is important to recognize that adolescents are very conscious of their body image and often compare themselves to their peers, hence the need for such feedback. Asking the parent to step out of the room respects the teenager's privacy and promotes open communication between the nurse and the teenager. Using age-appropriate communication is crucial to ensure that the teenager understands the information provided. Asking the parent to stay in the room may not be ideal as it can inhibit open discussion, and talking to the teenager as if they were a younger child is inappropriate and may undermine their autonomy and understanding.

5. What is the primary purpose of emergency planning?

A. Comply with the laws of the state.
B. Comply with the laws of the U.S.
C. Comply with both state and U.S. laws
D. Maintain safety

Correct answer: D

Rationale: The primary purpose of emergency planning is to ensure and maintain the safety of people and the preservation of objects, such as buildings and personal possessions during emergencies or disasters. While compliance with state and federal laws regarding emergency planning is important, the main goal is to prioritize life and safety. Choices A, B, and C focus on legal compliance, which is necessary but secondary to the fundamental objective of safeguarding lives and property in emergency situations.
