The nurse provides teaching regarding dietary intake of potassium to avoid an
electrolyte imbalance when a patient
Selected
Answer:
c. experiences anorexia and chronic oliguric
renal failure.
Correct
Answer:
a. has chronic heart failure that is treated with
diuretics.
Response
Feedback:
Chronic heart failure causes increased secretion of aldosterone, which often
causes hypokalemia by increasing renal excretion of potassium; most
diuretics used to treat heart failure also increase renal excretion of
potassium. Vitamin D and malabsorption of fat decreases absorption of
calcium, not potassium. Chronic oliguric renal failure causes decreased
excretion of potassium. An anorexic patient with chronic oliguric renal
failure should not increase dietary potassium.

Which is indicative of a left tension pneumothorax?
Selected
Answer:
b. Absent breath sounds on
the left
Correct
Answer:
b. Absent breath sounds on
the left
Response
Feedback:
A left pneumothorax results in absent breath sounds on the affected side.
Crackles will not be heard because breath sounds are not present.
Tracheal deviation occurs on the contralateral side. Pneumothorax results
in acute respiratory alkalosis.

When exposed to inhaled allergens, a patient with asthma produces large
quantities of
Selected
Answer:
c. Ig
G.
Correct
Answer:
a. Ig
E.
Response
Feedback:
During an allergic response, plasma cells produce large quantities of
IgE. IgG, IgA, and IgM are not part of the pathophysiology of asthma.

A person who has hyperparathyroidism is likely to develop
Selected
Answer:
d. hypercalce
mia.<\/p>\n\n\n\n
Correct
Answer:
d. hypercalce
mia.
Response
Feedback:
A person who has hyperparathyroidism is likely to develop hypercalcemia,
because parathyroid hormone causes calcium to come out of the bones
and go to the ECF. Hypokalemia, hyperkalemia, and hypocalcemia are not
the result of hyperparathyroidism.

Viral pneumonia is characterized by
Selected
Answer:
a. a dry
cough.
Correct
Answer:
a. a dry
cough.
Response
Feedback:
No exudative fluids are produced. Viral pneumonia does not produce
exudates, so the cough is non-productive. Ventilation-perfusion
imbalance does not usually occur in viral pneumonia.

Pneumocystitis is a term that refers to a
Selected
Answer:
b. fungal pneumonia secondary
to HIV.
Correct
Answer:
b. fungal pneumonia secondary
to HIV.
Response
Feedback:
Pneumocystitis is a fungal pneumonia secondary to HIV. Pneumocystitis is
not a viral pneumonia found in transplant recipients, a non-infectious
inflammation of the lung, or a pneumonia secondary to bladder infection.
\uf0b7 Question 7

Causes of hypomagnesemia include
Selected
Answer:
d. chronic
alcoholism.
Correct
Answer:
d. chronic
alcoholism.
Response
Feedback:
Hypomagnesemia is common with chronic alcoholism.
Hyperphosphatemia causes hypocalcemia. Oliguric renal failure and
clinical dehydration reduce magnesium excretion.

Selected
Answer:
d. IgE-mediated airway
inflammation.
