Grade A (Verified Answers)- WCU
Gas exchange occurs in which of the respiratory system's structures?
A) alveoli
B) terminal bronchioles
C) lungs
D) pulmonary vessels
E) pleurae - ANSWERA) alveoli
The alveoli allow air to come in indirect contact with the bloodstream through the
pulmonary capillary system. This alveolar membrane, which is one cell thick, allows
carbon dioxide to diffuse into the alveoli from the bloodstream and oxygen to diffuse
to the bloodstream from the alveoli. Sinuses are hollow spaces found in the skull.
The trachea is a structure that allows passage of gases to and from the gas exchange
units (alveoli). Bronchi are branches of the conducting airways that allow passage of
gases to and from the gas exchange units (alveoli).
A patient with heart failure reports awakening intermittently with shortness of
breath. Which terms appropriately describes this clinical manifestation?
A. Dyspnea
B. Cyanosis
C. Bradypnea
D. Paroxysmal nocturnal - ANSWERD. Paroxysmal nocturnal
Paroxysmal nocturnal dyspnea refers to intermittent attacks of severe dyspnea that
occur during the night. Dyspnea is a general term referring to difficulty breathing.
Cyanosis is the appearance of a blue or purple coloration of the skin or mucous
membranes due to the tissues near the skin surface being low on oxygen. Bradypnea
describes abnormal slowness of breathing.
What factor causes a congenital heart disease to produce cyanosis?
A. Left-to-right shunting of blood
B. Right-to-left shunting of blood
C. Ventricular septal obstruction
D. Atrial septal defect - ANSWERB. Right-to-left shunting of blood
Disorders that result in right-to-left shunting cause cyanosis. A left-to-right shunt
occurs when oxygenated blood from the left side of the heart or aorta flows back
into the right side to be recirculated through the lungs. The blood reaching the
,systemic circulation is oxygenated and the infant is not cyanotic (acyanotic defect).
However, the right side of the heart has an increased workload because of the extra
shunt blood. In time, the overload of the right side of the heart can result in right
ventricular hypertrophy and high right-sided heart pressures.
A patient education intervention that will help decrease the emergence of resistant
infections is to instruct the patient to
a. Take all the antibiotics ordered even if feeling well after a few days to prevent
antibiotic defiant bacteria
b. Have tests regularly to assess viral load in the body.
c. The patient will be free of signs and symptoms of infection. - ANSWERa. Take all
the antibiotics ordered even if feeling well after a few days to prevent antibiotic
defiant bacteria
The patient should take all the antibiotics ordered, even if feeling better, to eradicate
the moderately resistant microorganisms. Viruses are not impacted by antibacterial
medications. Sharing antibiotics indicates that the full course of the medication isn't
being taken, and so contributing to the development of resistant microorganisms. If
medication is stopped prematurely, moderately resistant organisms are selected for
and become the predominant species, making it more difficult to eradicate next
time.
Cellular hypoxia results in
a. Increased pH
b. Enhanced ATP activity
c. Loss of intracellular calcium
d. Failure of the sodium-potassium pump - ANSWERd. Failure of the sodium-
potassium pump
Hypoxia is a loss of oxygen to the cell that causes ATP activity to cease. ATP provides
the power required to drive the sodium-potassium pump. pH decreases in hypoxia
(respiratory acidosis). Hypoxia is a loss of oxygen to the cell that causes ATP activity
to cease. Deposits of calcium salts occur in conditions of altered calcium intake,
excretion, or metabolism.
What is the underlying problem common among all types of shock?
a. Generalized vasodilation
b. Inadequate cellular oxygenation
c. Impaired oxygen utilization by cells
d. Cardiac failure - ANSWERb. Inadequate cellular oxygenation
Although each type of shock has specific characteristics, all are associated with a
deficiency of cellular oxygen consumption. Inadequate cellular oxygenation may
result from decreased cardiac output, maldistribution of blood flow, or reduced
, blood oxygen content. The impaired oxygen utilization by cells may lead to cell
death, organ dysfunction, and stimulation of inflammatory reactions. Cardiac failure
can be an outcome, but is not a common cause in all types of shock. Vasodilation
occurs in only selective forms of shock. Faulty compensatory mechanisms may
contribute to the seriousness of all shocks but that is not the cause of all forms of
shock.
What is the name for the mRNA sequences that contain only the wanted segments?
a. Exon
b. Pre-mRNA
c. Spliceosomes
d. Introns - ANSWERa. Exon
An exon is the mRNA sequence that contains only the wanted segments. Introns are
the unwanted areas that are removed in the nucleus by a complex splicing process,
thus leaving exons. Pre-mRNA is the original RNA transcript before removal of bases
that are unnecessary. Spliceosomes are the areas of the nucleus that are a
specialized RNA protein complex that removes introns.
Thrombosis in the microcirculation throughout the body is called
a.) Stroke
b.) Atherosclerosis
c.) Myocardial infarction (MI)
d.) Disseminated intravascular coagulation (DIC) - ANSWERd. Disseminated
intravascular coagulation (DIC)
Thrombosis may also be initiated by a generalized reduction in flow and release of
vasoactive substances that occur in shock states. Systemic derangement in
coagulation takes place in disseminated intravascular coagulation (DIC), resulting in
thrombosis in the microcirculation throughout the body. A stroke results from the
obstruction of blood flow in or to the brain by a clot. Atherosclerosis is a circulatory
condition that results in the inability of vessels to regulate blood flow as a result of
the stiffening of their walls. An MI is a result of obstructed blood flow in a vessel
supplying the heart muscle itself.
Which term is used to identify hypertension that has a specific disease as its cause?
a. Primary
b. Secondary
c. Idiopathic
d. Essential - ANSWERb. Secondary
Secondary is the term given to hypertension that is secondary to a specific disease.
Idiopathic, primary, and essential hypertension are interchangeable terms for
hypertension that cannot be related to a specific disease/cause.
