NSG 505 EXAM 1 (2025/2026 FALL-
SPRING ) QUESTIONS AND ANSWERS
GRADED A+
Why must you stop oral anti-hypertensives for 48 hour before and after contrast?
Iodine may cause lactic acidosis
Digital subtraction angiography: category
x-ray
Digital subtraction angiography
Type of fluoroscopy with catheterization of vein or artery.
Used before or after vascular/tumor surgery.
Barium contrast: Directions
Can interfere with other tests.
Prep required before and after
,Barium contrast: Contraindications
Perforation
Colitis
What can you use instead of barium for perforation and/or colitis?
Gastrografin
What complications can contrast do to the body?
Nephrotoxicity
What can you do for nephrotoxicity d/t contrast?
Hydrate
Use low osmolar nonionic medium in minimal amount
DO NOT GIVE DIURETICS
,Radiation dose with X-rays
Lower than CT
Depends on length of time, number of images taken.
What test give the lowest amount of radiation?
Dental and DEXA.
Radiation: Mild reaction signs and interventions
N/V
Urticaria
Give antihistamine
Radiation: Intermediate reaction signs and interventions
Mouth/throat edema
Bronchospasm
Chest pain
Chills/ Fever
, Give antihistamines
(Possibly steroids, fluids, bronchodilators)
Radiation: Severe reaction signs and interventions
Edema
Hypotension
MI
Arrythmia
Seizure
Respiratory Failure
Give antihistamine, steroids, fluids, bronchodilators, intubation/ventilator,
pressors, antiepileptics.
When can delayed reactions to contrast occur?
2-6 hours after administration
magnetic resonance imaging (MRI)
a technique that uses magnetic fields and radio waves to produce computer-
generated images that distinguish among different types of soft tissue; allows us to
see structures within the brain.
