Chapter 24 : Caring for Clients With Valvular Disorders of the Heart Questions
Question 1 of 5
The client is scheduled for a percutaneous balloon valvuloplasty. The client asks the nurse how long it takes for the opening to close after the procedure. How should the nurse respond?
Correct Answer: C
Rationale: The opening usually closes within 6 months of a percutaneous balloon valvuloplasty. It usually takes longer than 1 week or 1 month, but less than 1 year.
Question 2 of 5
The nurse is caring for a client with a valvular disorder of the heart. What intervention should the nurse perform before administering the prescribed beta-blockers to clients with valvular disorders of the heart?
Correct Answer: C
Rationale: Before administering beta-blockers, the nurse should take the client's apical pulse. If the heart rate is less than 60 beats/minute, the nurse should withhold the drug and inform the primary healthcare provider. Oral anticoagulant therapy requires close monitoring of prothrombin time or INR. The nurse should also closely monitor clients receiving oral anticoagulants for episodes of bleeding. Overdosage of beta-blockers indicates bluish discoloration of the palms.
Question 3 of 5
The nurse is caring for a client with a valvular disorder. The client is at risk for decreased cardiac output. What nursing intervention should a nurse perform for this client?
Correct Answer: D
Rationale: The nurse should monitor urine output every 8 hours or more often if it is less than 500 mL/day. Renal output reflects the heart's ability to perfuse the renal arteries. The client should not perform any exercises and should be on bed rest. Keeping the client's legs horizontal and auscultating lung and heart sounds will not help in this condition.
Question 4 of 5
A client with aortic valve regurgitation is asking about the disease process. What would the nurse tell the client is the first sign of aortic valve regurgitation?
Correct Answer: A
Rationale: Tachycardia is one of the first signs of cardiac compensation. When valve damage affects the left ventricle, the client becomes aware of forceful heart contractions (palpitations). At first, palpitations occur only when lying flat or on the left side. Aortic valve regurgitation does not produce left-sided heart failure, pain, or dysrhythmias as the first symptom of disease.
Question 5 of 5
What disease process is mitral regurgitation associated with?
Correct Answer: D
Rationale: Mitral regurgitation is associated with rheumatic carditis and mitral valve prolapse. It is not associated with aortic stenosis, cellulitis, or pulmonary fibrosis. Aortic stenosis is a narrowing of the aortic valve, not related to the mitral valve. Cellulitis is inflammation in tissue, and pulmonary fibrosis is a scarring in the tissue of the lung.
