ATI RN Fundamentals Exam 2 Questions
Extract:
Question 1 of 5
The nurse is palpating a client's anterior chest wall and notices a course, crackling sensation over the skin surface. Which of the following should the nurse suspect from her findings?
Correct Answer: C
Rationale: Crepitus is a crackling sensation felt under the skin, often due to air in subcutaneous tissue. Friction rubs are heard or felt with pleural inflammation, tactile fremitus involves vibrations during speech, and adventitious sounds are abnormal lung sounds heard on auscultation.
Question 2 of 5
A group of nursing students are studying the conduction system of the heart. The nursing students should recognize that the pacemaker of the heart is known as
Correct Answer: A
Rationale: The sinoatrial (S
A) node is the heart's natural pacemaker, located in the right atrium. It generates electrical impulses that initiate each heartbeat and set the rhythm for the entire heart. This is a fundamental concept in cardiac physiology.
Question 3 of 5
The nurse explains the different parts of the ear to a client while teaching the client how to administer eardrops. The nurse pulls the upper ear that consists of movable cartilage and skin up and back and recognizes that this part is called the:
Correct Answer: A
Rationale: The auricle (pinna) is the external ear’s cartilage and skin, pulled up and back to straighten the ear canal for eardrop administration. The mastoid process is a bony structure, the outer meatus is the ear canal, and the concha is a depression in the auricle.
Question 4 of 5
The nurse is reviewing the sequence of the cardiac cycle. The nurse recognizes that the electrical stimulus of the cardiac cycle follows which sequence?
Correct Answer: B
Rationale: The correct sequence is SA node to AV node to bundle of His to bundle branches, initiating and spreading the electrical impulse for heart contraction. The SA node is the pacemaker, not the AV node, and Erb’s Point is an auscultation site, not part of the conduction system.
Question 5 of 5
A client was recently diagnosed with a heart murmur and is asking the nurse for more information. The nurse will educate the client that a heart murmur:
Correct Answer: A
Rationale: A heart murmur indicates turbulent blood flow through a valve, often due to valve disorders or structural issues. It’s not specifically due to inflexible chambers, inflammation, or always high-pitched from narrow valves.
