EXAM: RNC NIC Respiratory Exam| 175 Questions and
Answers
Congenital Adrenal Hyperplasia Correct Answer-Cortisol deficiency can be associated with
aldosterone deficiency= salt wasting
Salt wasting results in circulatory collapse- shock
Ambiguous genitalia
Treat with IV glucocorticoids
Ambiguous genitalia Correct Answer-21OH Deficiency- decreased cortisol production leads
to increased testosterone and androgens
congenital adrenal hyperplasia
Congenital adrenal hyperplasia electrolye imbalances Correct Answer-hyponatremia and
hyperkalemia
hydronephrosis Correct Answer-kidney swelling with urine due to blockage or obstruction
common cause uteropelvic junction obstruction
treat with prophylactic antibiotics to prevent infection of urine backing up
evaluate using VCUG
, EXAM: RNC NIC Respiratory Exam| 175 Questions and
Answers
PUV Correct Answer-Posterior urethral valves
Affects males only
Tissue blocks urethral valve and urine can't flow out of bladder
Causes: oligohydramnios, hydronephrosis, bladder distention, and lung hypoplasia
prune belly syndrome Correct Answer-underdeveloped abdominal wall
undescended testes (cryptorchidism)
urinary tract problems
Stages of lung development (5) Correct Answer-1. Embryonic
2. Pseudoglandular
3. Canalicular
4. Saccular
5. Alveolar
Embryonic stage of lung development Correct Answer-Up to 5 weeks
, EXAM: RNC NIC Respiratory Exam| 175 Questions and
Answers
Development of major airways, trachea, and bronchi
Pseudoglandular lung development stage Correct Answer-6-16 weeks
Formation of bronchi and bronchioles
Canalicular lung stage development Correct Answer-16-25 Weeks
Viable lungs with gas exchange
Surfactant begins forming; acini forming; capillaries forming
Saccular lung stage development Correct Answer-26-35 Weeks
Final branching of air spaces
Alveolar lung stage development Correct Answer-35 weeks-term
Alveoli increasing until age 8
Type 1 Pneumocytes Correct Answer-Line alveoli; responsible for gas exchange between
alveoli and capillaries
, EXAM: RNC NIC Respiratory Exam| 175 Questions and
Answers
Type 2 pneumocytes Correct Answer-Surfactant production
What is surfactant made up of Correct Answer-Phospholipids (lecithin) and proteins
L/S ratio Correct Answer-Lecithin-sphingomyelin ratio- predicts risk for RDS infants
L/S <2:1 = RDS
Antenatal corticosteroids and glucocorticoids purpose Correct Answer-Stimulates
surfactant production and matures lung cells
Antenatal steroids dosing Correct Answer-Initial course given <28 weeks
q24 hrs x 2
Fetal lung clearance Correct Answer-Active transport of chloride stops and cells pump Na
out and fluid follows. Fluid excreted by lymphatic system or reabsorbed
