Which action by the nurse will determine if therapies ordered for a patient with chronic constrictive pericarditis are effective?
Check the electrocardiogram (ECG) for ST segment changes.
Assess for the presence of jugular venous distention (VD).
Monitor for changes in the patient's sedimentation rate.
Assess for the presence of a paradoxical pulse.
The Correct Answer is B
Choice A rationale:
ST segment changes on an ECG are not typically associated with chronic constrictive pericarditis.
Choice B rationale:
Jugular venous distention (JVD) is a common sign of chronic constrictive pericarditis. If JVD is not present, it may indicate that the therapies are effective.
Choice C rationale:
While the sedimentation rate can indicate inflammation, it is not specific to chronic constrictive pericarditis.
Choice D rationale:
The presence of a paradoxical pulse is not typically associated with chronic constrictive pericarditis.
So, the correct answer is B, after analyzing all choices.

Correct Answer is D
Explanation
Choice A rationale:
While a history of heart attack indicates a general risk for heart disease, it is not specifically associated with an increased risk for infective endocarditis.
Choice B rationale:
Immunizations do not typically increase the risk for infective endocarditis.
Choice C rationale:
Family history of endocarditis does not necessarily increase the risk for infective endocarditis.
Choice D rationale:
Dental work can introduce bacteria into the bloodstream, which can lead to infective endocarditis, especially in individuals with prosthetic heart valves.
So, the correct answer is D, after analyzing all choices.
Correct Answer is A
Explanation
Choice A rationale:
Cardiac-specific troponin is a protein that is released into the bloodstream when there is damage to the heart muscle, such as during an acute myocardial infarction (AMI). It is considered the most specific marker for AMI because it is found only in heart muscle. The normal range for troponin I is between 0 and 0.04 ng/mL2.
Choice B rationale:
Myoglobin is a protein found in heart and skeletal muscles. While it can be elevated in AMI, it is not as specific as troponin because it is also found in skeletal muscles. The normal levels of myoglobin are 25 to 72 ng/mL4.
Choice C rationale:
Homocysteine is an amino acid in the blood, and high levels can increase the risk of heart disease. However, it is not specific for AMI5. The normal range of homocysteine levels are less than 15 micromoles per liter.
Choice D rationale:
C-reactive protein (CRP) is a marker of inflammation in the body and can be elevated in various conditions, including heart disease. However, it is not specific for AMI6. The normal CRP level is less than 0.9 milligrams per deciliter.
So, the correct answer is A, after analyzing all choices.
