1. A nurse is reviewing the definition of hypertension. According to ACC/AHA guidelines, stage 1
hypertension is defined as:
A. Systolic BP ≥140 or diastolic ≥90
B. Systolic BP ≥130 or diastolic ≥80
C. Systolic BP ≥120 or diastolic ≥70
D. Systolic BP ≥150 or diastolic ≥95
Correct Answer: B
Rationale: According to ACC/AHA guidelines, stage 1 hypertension is defined as systolic BP ≥130
mm Hg or diastolic BP ≥80 mm Hg. Normal BP is <120/<80. Elevated BP is 120–129/<80. Stage 2
hypertension is ≥140/≥90.
2. A nurse is reviewing the pathophysiology of hypertension. Blood pressure is calculated as:
A. Cardiac output × Systemic vascular resistance
B. Heart rate × Stroke volume
,C. Cardiac output × Heart rate
D. Systemic vascular resistance × Heart rate
Correct Answer: A
Rationale: Blood pressure is calculated as cardiac output (CO) multiplied by systemic vascular
resistance (SVR). CO is the product of heart rate and stroke volume. Hypertension develops
from increased CO, increased SVR, or both.
3. A nurse is teaching a patient about primary hypertension. What percentage of hypertension
cases are classified as primary (essential/idiopathic)?
A. 50–60%
B. 70–80%
C. 90–95%
D. 99%
Correct Answer: C
Rationale: Primary (essential/idiopathic) hypertension accounts for 90–95% of all hypertension
cases and has no identifiable cause. Secondary hypertension (5–10%) results from an underlying
condition such as renal disease, endocrine disorders, or medications.
, 4. A nurse is assessing a patient with secondary hypertension. Which underlying condition is a
common cause?
A. Stress
B. Renal artery stenosis
C. Obesity
D. Genetics
Correct Answer: B
Rationale: Secondary hypertension results from identifiable causes such as renal artery stenosis,
renal disease, endocrine disorders (e.g., Cushing's syndrome, hyperaldosteronism), or
medications. Stress, obesity, and genetics contribute to primary hypertension.
5. A nurse is teaching a patient why hypertension is called the “silent killer.” Which statement by
the patient indicates correct understanding?
A. “It always causes chest pain.”
B. “It is asymptomatic until target organ damage occurs.”
C. “It causes immediate death.”
D. “It is easily cured.”
Correct Answer: B
