NCAS Fundamentals 4

Question 1

A nurse is preparing to administer blood products. Which IV solution is compatible with blood transfusions?

Accepted Answer

Normal saline (0.9% NaCl)

Answer

Only normal saline (0.9% NaCl) is compatible with blood products; dextrose solutions can cause hemolysis and Lactated Ringer's can cause clotting.

Question 2

A patient on bed rest develops sudden onset of calf pain, warmth, and swelling. The nurse suspects deep vein thrombosis (DVT). What is the priority intervention?

Accepted Answer

Maintain bed rest and notify the physician immediately

Answer

Suspected DVT requires immediate physician notification and bed rest to prevent embolization of the clot.

Question 3

When administering an intradermal injection for a tuberculin skin test (TST), which finding indicates correct technique?

Accepted Answer

A wheal or bleb forms at the injection site

Answer

A pale wheal or bleb at the injection site confirms the medication was deposited in the dermis rather than subcutaneous tissue.

Question 4

A nurse is teaching a patient about pursed-lip breathing. Which patient statement indicates understanding?

Accepted Answer

'I will inhale through my nose and exhale slowly through puckered lips.'

Answer

Pursed-lip breathing involves nasal inhalation followed by slow exhalation through puckered lips to slow respiratory rate and reduce air trapping.

Question 5

A patient's nasogastric tube has been ordered for continuous feedings. Which assessment finding requires immediate action?

Accepted Answer

Absent bowel sounds with abdominal distension

Answer

Absent bowel sounds with abdominal distension may indicate an ileus or obstruction and requires immediate physician notification and tube feeding cessation.
