Deck 10: Special Equipment and Patient Care Environments

Question 1

What device measures pulmonary artery pressure (PAP)?

A) Suprapubic catheter
B) Swan-Ganz catheter
C) Endotracheal tube
D) Nasogastric tube

Answer 1

B
A Swan-Ganz catheter is a long tube inserted into a vein (usually the basilic or subclavian vein)and terminating in the pulmonary artery.A monitor attached to the catheter measures the pulmonary artery pressure.

Question 2

What level of oxygen saturation in the blood should be maintained when a patient exercises?

A) Minimum of 70 percent
B) Minimum of 80 percent
C) Minimum of 90 percent
D) Minimum of 95 percent

Answer 2

C
During exercise or physical activity,a minimum of 90 percent saturation should be maintained to avoid hypoxemia and possible respiratory dysfunction.If the SaO₂ falls below 90 percent and remains there,the patient's nurse or physician should be notified and the treatment should be discontinued.

Question 3

Which of the following values is most closely concerned with the body's ability to fight acute or chronic disease or infection?

A) RBC count
B) WBC count
C) Hgb
D) Hct

Answer 3

B
The white blood cell (WBC),also known as a leukocyte,is one of the body's defense mechanisms for fighting acute or chronic disease or infection.A person with a decreased WBC count caused by an immunosuppressed condition must be monitored carefully,and the caregiver must be certain to perform thorough hand hygiene,apply protective garments,and follow precautions before treatment to reduce the possibility of cross-contamination.

B) 90 mg/dL
C) 180 mg/dL
D) 540 mg/dL

Question 5

Which platelet count permits the performance of resistive exercises?

A) 20,000/mm3
B) 40,000/mm3
C) 60,000/mm3
D) 80,000/mm3

Question 6

How often does a PCA system allow a patient to self-administer a dose of medication?

A) Every 2 minutes

C) Every 30 minutes
D) Every hour

Question 7

Which of the following is a graphical record of the heart's electrical action?

A) EKG

Question 11

What information can be found using an ICP?

A) Intravenous pressure
B) Intrathoracic pressure
C) Intracranial pressure
D) Intermittent capsule pressure

Question 12

Which hemoglobin (Hgb)level would be a contraindication for any treatment requiring physical activity?

A) Greater than 16 g/dL
B) Greater than 8 g/dL
C) Less than 16 g/dL
D) Less than 8 g/dL

Question 13

What condition describes a significant decrease in an individual's red blood cell count?

A) Polycythemia
B) Anemia
C) Hypoxemia
D) Tachypnea

Question 14

Which bed oscillates in a cradle-like motion to reduce the amount of prolonged pressure on the patient's skin?

A) Air-fluidized support bed

C) Post-trauma mobility bed
D) Standard adjustable bed

Question 15

Which treatment is used for patients who experience ESRD?

A) Traction
B) Dialysis
C) External fixation
D) Internal fixation

Question 16

What type of exercise is recommended if a patient's INR is between 4.0 and 5.0?

A) Heavy resistive and aerobic exercise
B) Only light exercise; resistive exercises should be avoided
C) Low-intensity resistive exercises
D) Only limited bed mobility; all other physical activity should be deferred

Question 17

Which mode of oxygen delivery is most frequently used for patients who require longer periods of low to moderate concentrations of oxygen?

A) Nasal cannula
B) Oronasal mask
C) Tent
D) Tracheostomy catheter
