Question 1

: The APRN knows that causes of metabolic alkalosis occur due to? Select all.
Answer: A. Diarrhea. B. Diuretics (loop/thiazide). C. anxiety. D. Pain. E. Vomiting.

Answer 1

A. B.E. all three of these causes metabolic alkalosis due to the loss of hydrogen ions. Anxiety and pain cause respiratory alkalosis due to increased respiratory rate.

Question 2

A patient is on 4L NC, what percent of oxygen is this patient receiving?

Answer 2

This patient is receiving 36% of oxygen. 21% would be a patient on room air. 32% equals 3L and 5L would be 40%.

Question 3

A pulmonary embolism (PE) is an example of a type 1 respiratory failure. T/F

Answer 3

True

Reduced perfusion due to the PE with normal ventilation is known as a type 1 respiratory failure issue.

Question 4

A patient has been determined by ABG analysis to have a respiratory acidosis. The APRN recognizes that the patient is compensating when there is?
Answer: A. Increased HCO3. B. Decreased HCO3. C. Normalizing Ph. D. Increased base excess.

Answer 4

A patient has been determined by ABG analysis to have a respiratory acidosis. The APRN recognizes that the patient is compensating when there is?
Answer: A. Increased HCO3. B. Decreased HCO3. C. Normalizing Ph. D. Increased base excess.

Question 5

A sub acute cough is considered a cough lasting how long?

Answer 7

Question 8

Persons with no known risk factors for TB, what would be considered positive TB

Answer 8

Answer 9

Elevated HCO3

Question 10

An acute cough lasts how long

Answer 10

< 3 weeks

Question 11

What percentage of spirometry determines a mild obstruction pattern

Answer 11

FEV1 >70% predicted

Question 12

If your peak expiratory pressure is below for the typical average child height, what does this typically indicate

Answer 12

Asthma

Question 13

In a pulmonary function test, what does a low FEV1/FVC ratio indicate?

Answer 13

obstruction

Question 14

If an obstructive defect is present, the provider should determine if it is reversible based on the increase in FEV1 or FVC after what treament?

Answer 14

bronchodilator treatment

Question 15

ABGs
pH 7.2
PaCO2 6.5
HCO3 24

Answer 15

Resp acidosis

paCO2 normal is 4.7-6.0)
HCO3 (22-26)

Question 16

A patient with a history of ESRD is suspected of having a PE. The APRN orders which test for confirmation?

Answer 16

V/Q scan - which is indicated when the CTA is contraindicated- CTA requires good renal function

Question 17

When assessing a patients throat for postnasal drainage, what should you expect to find?

Answer 17

multiple bumps like a cobblestone appearance
