NUR 631 Final Exam Practice Questions and Answers

Removal of part of the liver leads to the remaining liver cells undergoing

compensatory - Answer✔️✔️-Compensatory hyperplasia is an adaptive mechanism

that enables certain organs to regenerate. For example, the removal of part of the

liver leads to hyperplasia of the remaining liver cells (hepatocytes) to compensate

for the loss.

a. An inflammatory disorder of small and medium-size arteries in the feet and

sometimes in the hands

extremities

c. A vasospastic disorder of the small arteries and arterioles of the fingers, and less

commonly, the toes

d. An autoimmune disorder of the large arteries and veins of the upper and lower

A patient is diagnosed with pulmonary disease and elevated pulmonary vascular

resistance. Which of the following heart failures may result from this condition?

a. Right heart failure

b. Left heart failure

c. Low-output failure


d. High-output failure - Answer✔️✔️-a. Right heart failure


Exp: Right heart failure is defined as the inability of the right ventricle to provide

adequate blood flow into the pulmonary circulation at a normal central venous

pressure. It most often results from the left heart failure when the increase in left

ventricular filling pressure that is reflected back into the pulmonary circulation is

severe enough. As pressure in the pulmonary circulation rises, the resistance to

right ventricular emptying increases.

What physical sign is the result of turbulent blood flow through a vessel?

a. Increased blood pressure during periods of stress

b. Bounding pulse felt on palpation

c. Cyanosis observed on excretion


d. Murmur heard on auscultation - Answer✔️✔️-d. Murmur heard on auscultation

Exp: Where flow is obstructed the vessel turns or blood flows over rough surfaces.

The flow becomes turbulent with whorls or eddy currents that produce noise

causing a murmur to be heard on auscultation such as occurs during blood pressure

measurement with a sphygomanometer. This selection is the only option that

accurately identifies the physical sign of turbulent vascular blood flow. pg 1113

Which congenital heart defects occur in trisomy 13, trisomy 18 and down

syndrome?

a. Coarctation of the aorta and pulmonary stenosis

b. Tetralogy of Fallot and persistent truncus arteriosus

c. Atrial septal defect and dextrocardia


d. Ventricular septal defect and patent ductus arteriosus - Answer✔️✔️-d. Ventricular

septal defect and patent ductus arteriosus

Exp: Congenital heart defects that are related to dysfunction of trisomy 13, trisomy

18 and down syndrome include VSD and PDA see Table 33-2 The other defects are

not associated with dysfunction of trisomy 13 or 17 and down syndrome. pg 1200

thrill on palpation. These clinical findings are consistent with which congenital

heart defect?

a. Atrial septal defect

b. Ventricular septal defect

c. Patent ductus arteriosus


d. Atrioventricular canal defect - Answer✔️✔️-c. Patent ductus arteriosus


Exp: If pulmonary vascular resistance has fallen then infants with will

characteristically have a continuous machine/type murmur best heard at the left

upper sternal border throughout systole and diastole. If the PDA is significant then

the infant also will have bounding pulses an active precordium, a thrill on

palpation and signs and symptoms of pulmonary over circulation. The

presentations of the other congenital heart defects are not consistent with the

described the symptoms pages 1203-1204

Which compensatory mechanism is spontaneously used by children diagnosed with

tetralogy of Fallot to relieve hypoxic spells?

a. Lying on their left side

b. Performing the valsalva maneuver

c. Squatting
