Charity School Of Nursing Nurs 117 ANS Questions with Correct
Answers (Grade A+)
Question 1: What happens when Alpha 1 is blocked?
Answer: vasodilation, miosis, Suppresses ejaculation, less contraction of smooth muscles in bladder neck &
prostate gland, low B/P; reflex tachycardia
Question 2: What happens if Beta 1 is blocked?
Answer: Lesser Heart rate, lesser myocardial contraction
Question 3: What happens if beta 2 is blocked?
Answer: bronchioles constrict, contraction of uterus and it inhibits glycogenesis
Question 4: What do beta 1 blockers affect?
Answer: The heart
Question 5: What do beta 2 blockers affect?
Answer: The lungs
Question 6: What are the primary neurotransmitters for Adrenergic system?
Answer: Norepinephrine, epinephrine & dopamine
Question 7: How does the adrenergic system affect the heart?
Answer: Increases heart rate
Question 8: What does Beta 1 stimulate?
Answer: Perfusion
Question 9: What happens when receptor cells bind to Beta 1?
Answer: æ Norepinephrine, epinephrine & dopamine are released æ increase cardiac contractility æ increase
HR æ increase renin: which caused an increase inBP æ increase intraocular pressure
Question 10: What happens when receptor cells bind to Beta 2?
Answer: æ Epinephrine is released æ Bronchioles dilate æ GI & uterine relaxation increase blood flow to
skeletal muscles & increased blood glucose
