The nurse knows that which hormones play a role in regulating blood pressure?
Standard Text: Select all that apply.
1. Estrogen
2. Antidiuretic hormone (ADH)
3. Testosterone
4. Renin
5. Atrial natriuretic peptide (ANP)
Correct Answer: 2,4,5
Rationale 1: Estrogen does not play a role in regulating blood pressure.
Rationale 2: The antidiuretic hormone (ADH) plays an important role in regulating blood pressure. ADH, also known as vasopressin, is a potent peripheral vasoconstrictor that quickly increases blood pressure.
Rationale 3: Testosterone does not play a role in regulating blood pressure.
Rationale 4: The renin-angiotensin-aldosterone system (RAAS) plays an important role in regulating blood pressure. As blood pressure falls, the enzyme renin is released by the kidneys. Through a two-step pathway, angiotensin II is formed, which subsequently increases CO and constricts arterioles to return blood pressure to original levels.
Rationale 5: The atrial natriuretic peptide (ANP) plays an important role in regulating blood pressure. ANP has multiple effects, all of which attempt to return blood pressure to original levels.
