|
|
Normal cardiac changes that occur during pregnancy include: nurs 6512 week 6 midterm exam. |
|
|
|
Response Feedback: |
The maternal blood volume increases by 40% to 50% due to an increase in plasma volume. The heart works harder to accommodate the increased heart rate and stroke volume (both equal cardiac output), therefore resulting in the increase in left ventricle wall thickness and mass. The blood volume returns to prepregnancy levels within 3 to 4 weeks after delivery. As the uterus enlarges and the diaphragm moves upward, the heart is shifted horizontally and there is a slight axis rotation. |

An idiopathic spasm of arterioles in the digits is called: |
|
|
|
Response Feedback: |
Raynaud disease is idiopathic, intermittent spasm of the arterioles in the digits, which causes skin pallor. Arteriosclerosis obliterans is the occlusion of the blood supply to the extremities by atherosclerotic plaques. Giant cell arteritis is a generalized inflammatory disease that affects arteries of the carotid, temporal, and occipital arteries. Arteriovenous fistula is a pathologic communication between an artery and a vein. An aneurysm is dilation of an artery caused by a weakness in the arterial wall. They occur in the aorta, renal, femoral, and popliteal arteries. |

|
|
A bounding pulse in an infant may be associated with: |
|
|
|
Response Feedback: |
A bounding pulse is associated with a large left-to-right shunt produced by a patent ductus arteriosus. A weaker or thinner pulse represents diminished cardiac output or peripheral vasoconstriction. A difference in pulse amplitude between upper extremities, or between femoral and radial pulses, and absence of the femoral pulse suggests a coarctation of the aorta. Painful swollen extremities are usually a sign of venous occlusion. nurs 6512 week 6 midterm exam. |

|
|
In the adult, the apical impulse should be most visible when the patient is in what position? |
|
|
|
Response Feedback: |
In most adults, the apical impulse should be visible at about the midclavicular line in the fifth left intercostal space, but it is easily obscured by obesity, large breasts, or muscularity. The apical impulse may become visible only when the patient sits upright and the heart is brought closer to the anterior wall. A visible and palpable impulse when the patient is supine suggests an intensity that may be the result of a problem. nurs 6512 week 6 midterm exam. |

|
|
The best time to observe and count respirations is: |
|
|
|
Response Feedback: |
Respiratory patterns change as the patient speaks and sleeps. Attempting to count during weighing would make the patient self-conscious and affect respiratory rate. Counting respirations while you palpate the pulse does not make the patient self-conscious because the patient expects you to be counting the pulse. |

|
|
|
Response Feedback: |
Unless specially modified, the stethoscope does not amplify sound, nor does it filter sound or pinpoint focal sounds. The stethoscope does transmit sound waves from the source to the ear. The diaphragm is the better source because it transmits the normally high-pitched sounds of the lung and it has a broader area to listen from. |

A palpable rushing vibration over the base of the heart at the second intercostal space is called a: |
|
|
|
Selected Answer: |
thrill. |
Correct Answer: |
thrill. |
Response Feedback: |
A thrill is a fine, palpable, rushing vibration; a palpable murmur. Cardiac thrills generally indicate a disruption of the expected blood flow related to some defect in the closure of one of the semilunar valves (generally aortic or pulmonic stenosis), pulmonary hypertension, or atrial septal defect. A heave or lift is a more vigorous apical impulse. A thrust is to move forward suddenly and forcibly. A murmur is an auscultated sound caused by turbulent blood flow. |

The major heart sounds are normally created by: |
|
|
|
Response Feedback: |
At the beginning of systole, ventricular contraction raises the pressure in the ventricles and forces the mitral and tricuspid valves closed, which produces the first heart sound S1 lub. When the pressure in the ventricles falls, when the ventricles are almost empty, below that of the aorta and pulmonary artery, the aortic and pulmonic valves close, producing the second heart sound S2 dub.

|
The carotid pulse should coincide with which heart sound? |
|
|
|
Response Feedback: |
S1 marks the beginning of systole. S1 coincides with the rise (upswing) of the carotid pulse. Instruct patients to breathe normally and then hold their breath on expiration. Listen for S1 while you palpate the carotid pulse. S2 marks the start of diastole. S3-4 is an abnormal summation gallop sound. nurs 6512 week 6 midterm exam. |

The condition in which a patient s heart is either rotated or displaced to the right or is situated as a mirror image of the expected position is called: |
|
|
|
Response Feedback: |
Dextrocardia occurs when the heart is displaced or rotated to the right or is a complete mirror image of the expected finding. Amyloidosis is a metabolic disorder marked by amyloid deposits in organs and tissues. Cardiomyopathy is the deterioration of heart muscle function. Coarctation is the compression of the walls of a vessel such as an aortic coarctation. Situs inversus occurs when the heart and stomach are displaced to the right and the liver is located to the left. |

In what position can the mediastinal crunch (Hamman sign) be heard best? |
|
|
|
Response Feedback: |
Hamman sign occurs with mediastinal emphysema. The adventitious breath sounds are synchronous with the heartbeat and are heard best when the patient leans to the left or lies down on the left side (these maneuvers bring the heart muscle closer to the chest wall). |

Expected respiratory changes of normal aging include: |
|
|
|
Response Feedback: |
In older adults, chest expansion is decreased and there is less use of respiratory muscles due to muscle weakness. The dorsal curve of the thoracic spine is prominent with flattening of the lumbar curve with bony landmarks becoming more prominent due to loss of subcutaneous tissue. nurs 6512 week 6 midterm exam. |

The major heart sounds are normally created by: |
|
|
|
Response Feedback: |
At the beginning of systole, ventricular contraction raises the pressure in the ventricles and forces the mitral and tricuspid valves closed, which produces the first heart sound S1 lub. When the pressure in the ventricles falls, when the ventricles are almost empty, below that of the aorta and pulmonary artery, the aortic and pulmonic valves close, producing the second heart sound S2 dub. Valve opening is usually a silent event. |

Breath odors may clue the examiner to certain underlying metabolic conditions. The odor of ammonia on the breath may signify: |
|
|
|
Response Feedback: |
The breath smell described as ammonia-like suggests uremia, a renal condition; cinnamon suggests tuberculosis; musty fish or clover suggests hepatic failure; sweet and fruity suggests diabetic ketoacidosis; and foul or feculent suggests intestinal obstruction. |

In which patient situation would you expect to assess tachypnea? |
|
|
|
Response Feedback: |
In metabolic acidosis, the body compensates by increasing the respiratory rate in order to blow off the excess carbon dioxide. The other choices cause respiratory depression. |

The spread of the impulse through the ventricles (ventricular depolarization) is depicted on the ECG as the: nurs 6512 week 6 midterm exam. |
|
|
|
Response Feedback: |
The QRS complex is the spread of a stimulus through the ventricles and is measured as less than 0.10 second. The P wave is the spread of a stimulus through the atria. The PR interval is the time from the initial stimulation of the atria to initiation of stimulation of the ventricles. The T wave is the return of stimulated ventricular muscle to a resting state. The U wave is a small deflection sometimes seen just after the T wave. |

Contraction of the ventricles causes: |
|
|
|
Response Feedback: |
When the ventricles contract the semilunar valves, the pulmonic and aortic valves open, causing blood to rush into the pulmonary artery and the aorta. At this time the tricuspid and mitral valves close, preventing backflow into the atria. When the atria contract, the tricuspid and mitral valves open, allowing blood flow into the ventricles. When the ventricles relax during diastole (ventricles are filling), the aortic and pulmonic valves close, preventing backflow into the ventricles. nurs 6512 week 6 midterm exam. |
