Multiple Choice

1. The nursing instructor is explaining cardiac function to the senior nursing class. The instructor explains that blood is ejected into circulation as the chambers of the heart become smaller. The instructor categorizes this action of the heart as what?
A) Systole

B) Diastole
C) Hypertension D) Ejection fraction

Ans: A
Chapter: 26
Client Needs: D-4
Cognitive Level: Comprehension
Difficulty: Moderate
Integrated Process: Nursing Process
Objective: 1
Page and Header: 686, Anatomic and Physiologic Overview

Feedback: Systole is the action of the chambers of the heart becoming smaller and ejecting blood. This action of the heart is not diastole, hypertension, or ejection fraction.

2. During a shift assessment, the nurse is assessing the point of maximum impulse (PMI). Where will the nurse best palpate the PMI?
A) Left midclavicular line of the chest wall at the seventh intercostal space
B) Left midclavicular line of the chest wall at the fifth intercostal space

C) Right midclavicular line of the chest wall at the seventh intercostal space D) Right midclavicular line of the chest wall at the fifth intercostal space

Ans: B
Chapter: 26
Client Needs: D-4
Cognitive Level: Application
Difficulty: Moderate
Integrated Process: Nursing Process
Objective: 2
Page and Header: 686, Anatomic and Physiologic Overview

Feedback: The left ventricle is responsible for the apical beat or the point of maximum impulse, which is normally palpated in the left midclavicular line of the chest wall at the fifth intercostal space. Therefore options A, C, and D are incorrect.

3. The instructor is teaching the beginning nursing class how to calculate pulse pressure. If the patient’s systolic pressure was 122 mm Hg and the diastolic pressure was 75 mm Hg, what would the pulse pressure be?
A) 57

B) 60 C) 54 D) 47

Ans: A
Chapter: 26
Client Needs: D-4
Cognitive Level: Analysis
Difficulty: Easy
Integrated Process: Nursing Process
Objective: 4
Page and Header: 698, Assessment of the Cardiovascular System

Feedback: Pulse pressure is the difference between the systolic and diastolic pressure. The only correct option is A.

4. The nurse is caring for a patient admitted with unstable angina. The laboratory result for the initial troponin I is elevated in this patient. The nurse recognizes what?
A) This is only an accurate indicator of myocardial damage when it reaches its peak in 24 hours.

B) Because the entry diagnosis is unstable angina, this is a poor indicator of myocardial injury. C) This is an accurate indicator of myocardial injury.
D) It is only an accurate indicator of skeletal muscle injury.

Ans: C
Chapter: 26
Client Needs: D-4
Cognitive Level: Analysis
Difficulty: Moderate
Integrated Process: Nursing Process Objective: 3
Page and Header: 705, Diagnostic Evaluation

Feedback: Troponin I is specific to cardiac muscle and is elevated within 3 to 4 hours after myocardial injury. Options A, B, and D are incorrect. Even with a diagnosis of unstable angina, this is an accurate indicator of myocardial injury.

5. You are conducting patient teaching about cholesterol levels in the body. When discussing the patient’s elevated LDL and lowered HDL levels, the patient shows an understanding of the significance of these levels by stating what?
A) “Increased LDL and decreased HDL increase my risk of coronary artery disease.”

B) “Increased LDL and decreased HDL decrease my risk of coronary artery disease.”
C) “The decreased HDL level will increase the amount of cholesterol moved away from the artery walls.”
D) “The increased LDL will decrease the amount of cholesterol deposited on the artery walls.”

Ans: A
Chapter: 26
Client Needs: D-3
Cognitive Level: Application
Difficulty: Moderate
Integrated Process: Teaching/Learning Objective: 3
Page and Header: 705, Diagnostic Evaluation

Feedback: Elevated LDL levels and decreased HDL levels are associated with a greater

incidence of coronary artery disease.
