The only definitive way to determine the presence of malignant cells is to perform
a. laboratory tests.
b. a tissue biopsy.
c. an MRI.
d. a CT scan.
Question 2Recent exacerbation of a patient's mitral valve regurgitation prompted her cardiologist to perform a mitral valve replacement in which the patient received a mechanical valve.
In the weeks following the patient's surgery, which of the following blood tests will be most relevant to the patient's potential complications?
A) Blood urea nitrogen (BUN) and creatinine
B) Serum potassium level
C) White blood cell (WBC) differential
D) International normalized ratio (INR)
Question 3Which are characteristics of malignant tumors?
a. Smooth, well defined; movable when palpated
b. Resembles parent tissue; rarely fatal
c. Rate of growth varies; rarely contained within a capsule
d. Remains localized; slow growth
Question 4A 73-year-old man with aortic stenosis has had percutaneous aortic balloon valvuloplasty performed because he is not a candidate for valve replacement. Following this procedure, the nurse should prioritize assessments related to:
A) Anginal pain
B) Signs and symptoms of myocardial infarction
C) Ventricular arrhythmias
D) Pericarditis
Question 5A patient with a history of primary hypertension has undergone echocardiography after being referred to a specialist for blood pressure management. The patient's echocardiogram revealed ventricular hypertrophy and a decreased ejection fraction.
The nurse who is providing care for this patient should recognize that these findings are characteristic of what valvular disorder?
A) Mitral valve regurgitation
B) Mitral valve stenosis
C) Aortic stenosis (AS)
D) Tricuspid regurgitation
Question 6Seeking medical attention when any cancer warning signs occur is frequently delayed because of
a. difficulty accessing a physician or getting a referral consult.
b. lack of knowledge of the seven warning signs of cancer.
c. fear of the possible diagnosis of cancer and hoping signs will go away.
d. self-examination being complex and difficult to perform.
Question 7A patient, age 43, had a biopsy of a lump in her right breast that revealed a benign tumor. The nurse explains to her that a benign tumor differs from a malignant tumor in that benign tumors
a. do not cause damage to adjacent tissue.
b. are simply an overgrowth of normal cells.
c. do not spread to other tissues and organs.
d. frequently recur in the same site.
Question 8A patient has been diagnosed with mitral valve prolapse (MVP) following an echocardiogram and will begin treatment imminently. When planning this patient's care, the nurse will prioritize:
A) Protecting the patient from infection
B) Preserving the patient's existing level of function
C) Reducing the patient's risk of ischemic heart disease
D) Teaching the patient the signs and symptoms of pericardial effusion
