Bio 669 - Exam 3 Pulmonary & Renal Questions AND Correct Answers
A 1 year old child presents with tachypnea, labored breathing and wheezing following onset of what
appears to be a cold / viral infection. The most likely diagnosis is? - ✔✔bronchiolitis
A person with lupus is most likely to have fatal complications arising from: - ✔✔Immune complex
deposition to the glomeruli leading to severe glomerulonephritis
A pulmonary embolus creating alveolar dead space will likely have which of the following effects? -
✔✔High V/Q ratio
Acidosis will ______ the affinity of oxygen to hemoglobin and thus would be considered a _________
shift in the oxyhemoglobin disassociation curve - ✔✔decrease, right
Acute cystitis is best described as? - ✔✔Inflammation of the bladder, pressure with frequency, dysuria,
and lower abdominal &/or suprapubic pain, lower back pain.
Because sweat if essentially a sodium solution with an osmolarity less than that of plasma, severe
sweating leads to a reduction in plasma volume and an increase in plasma osmolarity. How do these
affect the secretion of ADH? - ✔✔Both the decrease in plasma volume and the increase in plasma
osmolarity stimulates ADH secretion.
Chronic inflammation of the bronchial wall, with destruction of the elastic and muscular components
best describes? - ✔✔Bronchiectasis
Edema of the alveolar membrane is a problem because:
A. Indicates cancerous changes
B. Restricts perfusion of the alveolus
C. It interferes with normal gas exchange
D. It decreases air resistance in that area - ✔✔C. It interferes with normal gas exchange
Empyema results from? - ✔✔An infected pleural effusion
, Enlargement of the renal pelvis and calyces due to an upper urinary tract obstruction would best be
termed a? - ✔✔Hydronephrosis
Glucose reabsorption occurs primarily in the: - ✔✔proximal convoluted tubule
How is most of the CO2 transported in the blood? - ✔✔As bicarbonate that can be converted back to
CO2
How is the alveolar volume measured?
A. Measuring tidal volume and breathing rate over the course of a minute.
B. Measuring the total amount of air that can be held in the lungs.
C. Subtracting the residual volume from the total lung capacity.
D. Indirectly by measuring PaO2 or PaCO2 - ✔✔D. Indirectly by measuring PaO2 or PaCO2
In response to low alveolar PO2 - ✔✔Vascular smooth muscle controlling flow that alveolus will
constrict
intercalated cells - ✔✔Secrete H2, reabsorb K and bicarb
modified smooth muscle cells that secrete renin are the: - ✔✔Juxtaglomerular cells
Of the folllowing cell types which is responsible for secreting surfactant? - ✔✔Type II Alveolar cells
Principle cells of collecting duct - ✔✔Reabsorb Na & secrete K
Severe bronchospasm not responsive to normal measures (beta agonist bronchodilators) is best
described as? - ✔✔Status asthmatics
