place.
Stage One of Hypertension
This first stage of the four stages of hypertension is referred to as
the "normal" stage. A person's systolic will be at less than 130 mm
Hg and their diastolic will be less than 80 mm Hg. At this point, a
person will not require treatment, as their blood pressure is

normal. It is important, however, to monitor the blood pressure to
ensure that it is staying normal.
Stage Two of Hypertension
This stage is referred to as prehypertension. Systolic will be
between 130 and 139 mm Hg and diastolic will be between 80 and
89 mm Hg. Prehypertension is exactly what it sounds like, the stage
before someone crosses into hypertension. A person who is at
stage two of hypertension is at risk for developing high blood
pressure, but still has a chance to avoid it.
At this stage, a person has some risk of experiencing heart disease
or a stroke. Medication is typically not used at this point because it
hasn't been proven to help against potential strokes or heart
disease at this stage. However, a person should still try to make
lifestyle changes to avoid hypertension. This could mean quitting
smoking or changing the way you eat. Exercise is a great way of
lowering your blood pressure, as is trying the DASH diet.
Stage Three of Hypertension
Stage three of hypertension is actually referred to as "stage 1."
Systolic is between 140 and 159 mm Hg and diastolic is between 90
and 99 mm Hg. A person at stage 1 is in danger of a variety of

health complications due to moderate hypertension. At this point, a
person would be expected to try medication to reduce their blood
pressure and risk of heart disease and/or stroke. These drugs
include ACE inhibitors, angiotensin
Straining during defecation -
correct answer ✅-vagal stimulation, which slows the heart rate,
occurs during straining while defecating, taking rectal
temperatures, completion of enemas, and digital removal of
impacted stool
sympathetic nervous system -
correct answer ✅Fight or flight - the division of the autonomic
nervous system that arouses the body, mobilizing its energy in
stressful situations.
Breathe quicker, palms sweat, heart races, pupils widen, mouth dry
and hard to spk - stressed.
Heart - increases rate and strength of contraction
Bronchial tubes - dilated which increases airflow
Iris of eye - dilated pupil enlarges
Blood vessels - constrict
, LVN Unitek Mid-term Review Exam
Questions & Answers (Grade A+)
Sweat glands - stimulates
Intestine - inhibits motility and secretion
Uterus - relaxes muscle
Adrenal medulla - stimulates secretion of epinephrine and
norepinephrine
Salivary glands - stimulates thick secretion
Urinary system: bladder wall - relaxes muscle
Internal sphincter: closes
Nociceptors (pain receptors) -
correct answer ✅chemoreceptors that respond to chemicals
released by damaged tissue (caused by chemicals, ischemia,
distinction or distortion)
parasympathetic nervous system -
correct answer ✅the division of the autonomic nervous system
that calms the body, conserving its energy. Feed and breed division.
Decreases heart rate
Constricts bronchial tubes so airflow decreases
Iris constricts
