Xray interpretation

Question 1

What are air leaks in a medical context?

Answer 1

Abnormal escape of air from the lung or airway into the surrounding tissues or pleural space

Commonly associated with conditions like pneumothorax and respiratory distress syndrome.

Question 2

What does ETT stand for?

Answer 2

Endotracheal Tube

A tube inserted into the trachea to maintain an open airway.

Question 3

What is the purpose of an OG tube?

Answer 3

Orogastric Tube

Used for feeding or medication administration in patients unable to swallow.

Question 4

What does UAC stand for?

Answer 4

Umbilical Artery Catheter

A catheter placed in the umbilical artery for monitoring and medication administration.

Question 5

What does UVC refer to?

Answer 5

Umbilical Vein Catheter

Used for intravenous access in neonates.

Question 6

What are central lines used for?

Answer 6

Long-term intravenous access

Allows for the administration of medications, fluids, and nutrition.

Question 7

What condition is characterized by difficulty in lung expansion?

Answer 7

Respiratory Distress Syndrome

Commonly seen in premature infants due to surfactant deficiency.

Question 8

TTN stands for what in a medical diagnosis?

Answer 8

Transient Tachypnea of the Newborn

A temporary condition causing rapid breathing in newborns.

Question 9

What is pneumonia?

Answer 9

An infection that inflames the air sacs in one or both lungs

Can cause symptoms such as cough, fever, and difficulty breathing.

Question 10

What are the factors affecting the quality of chest X-rays?

Answer 10

Positioning, motion, tube angulation, film exposure

Proper technique is crucial for accurate interpretation.

Question 11

What does an inspiratory film show?

Answer 11

8 to 9 ribs expanded, normal cardiac size, right hemidiaphragm higher than left

Indicates proper lung inflation.

Question 12

What indicates an expiratory film?

Answer 12

7 ribs expanded or less, large cardiac size, lung fields opaque

Suggests inadequate lung expansion.

Question 13

What is the significance of film exposure in X-ray interpretation?

Answer 13

Underexposed films appear whitewashed; overexposed films appear too dark

Proper exposure is essential for visualizing anatomical structures.

Question 14

What does the term ‘hypoexpansion’ refer to?

Answer 14

Inadequate lung inflation

Often indicated by the number of ribs visible on an X-ray.

Question 15

What is the basic principle of radiology concerning x-ray absorption?

Answer 15

Differential absorption of x-ray photons by different types of body tissue produces an image

Tissues absorb varying amounts of x-ray photons based on density.

Question 16

What are the four kinds of body tissue that can be differentiated in X-ray imaging?

Answer 16

• Tissue containing gas
• Fatty tissue
• Tissue containing calcium
• Tissues of water density

Each type appears differently on X-ray films.

Question 17

What does NEC stand for in a medical context?

Answer 17

Necrotizing Enterocolitis

A serious gastrointestinal problem that mostly affects premature infants.

Question 18

Fill in the blank: Bone and metal fragments absorb x-ray photons and appear ______ on film.

Answer 18

white

This is due to their high density.

Question 19

Fill in the blank: Liquid and tissue appears ______, although less dense than air.

Answer 19

white

Important for differentiating various tissues in imaging.

Question 20

True or False: The right patient, right time, and right view are critical for effective X-ray interpretation.

Answer 20

True

Accuracy in patient identification and timing enhances diagnostic reliability.
