The client has been diagnosed with aortic regurgitation. Which nursing data is most significant in identifying the cause for this disorder?
- A. Obesity
- B. Tobacco use
- C. Fen-Phen
- D. Lack of exercise
Correct Answer: C
Rationale: The incidence of mitral and aortic regurgitation increased by as much as 36% in 1997, due to the use of fenfluramine with phentermine (Fen-Phen) for weight loss. Obesity, tobacco use, and lack of exercise have been identified as risk factors for heart disease but not a significant identified cause for aortic regurgitation.

A client with progressive mitral valve prolapse is experiencing sympathetic nervous system symptoms in addition to prolapse symptoms. Which teaching point should be stressed by the nurse to minimize these effects?
- A. Antibiotic therapy before invasive procedures
- B. Low-dose aspirin daily
- C. Avoid caffeine.
- D. Decrease fluid and sodium intake.
Correct Answer: C
Rationale: The symptoms associated with sympathetic nervous response (anxiety, agitation, nervousness, and palpitations) are often managed with antianxiety medications and advisement to avoid caffeine and over-the-counter medications that contain stimulants. Periodic antibiotic therapy use before an invasive procedure is not associated with sympathetic nervous system symptoms. Low-dose aspirin is used to prevent thrombus formation. Decreasing fluid and sodium intake is indicated for the control of congestive failure.
A client is scheduled for transcatheter aortic valve implantation (TAVI). Which statement from the nurse best explains this procedure to family members?
- A. A small incision in the chest wall will allow for valve repair.
- B. A catheter is used for partial replacement of the valve.
- C. A small window incision is made so a pig valve can replace the diseased valve.
- D. A complete aortic valve replacement is the best surgical treatment.
Correct Answer: B
Rationale: TAVI procedure is a minimally invasive procedure (no incision) that uses balloon valvuloplasty, stent, and partial replacement of the diseased valve using a portion of a pig valve. The TAVI is mostly used in older adults who are at high risk for the complete aortic valve replacement and helps to relieve recurring symptoms.
Which symptom is most important in determining the diagnosis and nursing care for a client experiencing pulmonary hypertension?
- A. Increased stroke volume
- B. Bradycardia
- C. Frothy sputum
- D. High systolic pressure
Correct Answer: C
Rationale: Tachycardia, low systolic pressure, and decreased stroke volume are symptoms associated with pulmonary hypertension. A productive cough with pink-tinged frothy sputum can indicate progression of the disorder and need for treatment.
The nurse provides care for an older adult client who is diagnosed with valvular heart disease. On auscultation of the client's heart sounds, the nurse notes an erratic heart rhythm. Which age-related change is the most likely cause for this finding?
- A. A stiffening of the aorta
- B. A decrease in metabolism
- C. An increase in thirst sensation
- D. A thinning of the mitral valve
Correct Answer: A
Rationale: Age-related effects, such as stiffening of the aorta, calcification, and fibrotic thickening (not thinning) of the mitral and aortic valves, contribute to development of symptoms (e.g., increased systolic blood pressure [BP], dangerous arrhythmias [erratic heart rhythms or rates that are too fast or slow] sometimes referred to as dysrhythmias) and complications (e.g., increased myocardial oxygen demand, heart failure, and alterations in cardiac output) in the older adult with valvular heart disease. A decrease in metabolism is an age-related effect for clients with valvular heart disease; however, this affects the dosage of prescribed medication and is not the cause of the client's dysrhythmia. A decrease, not increase, in thirst sensation is an age-related change that could lead to dehydration, and, thus, changes in the client's heart rhythm.
A client is being evaluated for mitral stenosis versus mitral insufficiency. Which of the following symptoms would the nurse find in either condition?
- A. Angina
- B. Syncope
- C. Murmur
- D. High blood pressure
Correct Answer: C
Rationale: Mitral stenosis and mitral insufficiency both create regurgitation of blood back through the mitral valve which can be heard as a murmur. Angina and syncope are not common and would only be exhibited if decrease nourishment of the cardiac muscle and organs occur. Hypertension may be an underlying condition but not necessarily associated with both disorders.
