✍️ Sample CHS Questions & Answers
1. A postmenopausal woman on hormone replacement therapy (HRT) is noted to have new-onset hypertension. Which component of HRT is primarily implicated?
Oral estrogens stimulate hepatic angiotensinogen synthesis, increasing angiotensin II levels and causing sodium retention and hypertension; transdermal estrogen avoids first-pass hepatic effect.
2. In essential hypertension, increased sympathetic nervous system activity contributes to elevated blood pressure primarily through which mechanism?
Sympathetic overactivity raises blood pressure by increasing peripheral vascular resistance through vasoconstriction and promoting renal sodium and water retention via beta-adrenergic stimulation of renin release.
3. A 58-year-old woman has office BP of 158/96 mmHg but normal ABPM (average 122/78 mmHg). This pattern is best described as:
White-coat hypertension is characterized by elevated office BP with normal out-of-office (ABPM or home) readings.
4. Masked hypertension is defined as:
Masked hypertension occurs when office BP is normal but out-of-office measurements reveal true hypertension, carrying significant cardiovascular risk.
5. What are the five process groups in CHS project management?
The five groups cover the lifecycle: Initiating, Planning, Executing, Monitoring & Controlling, and Closing.
6. According to NFPA 99, which class of hyperbaric chamber is defined as a chamber intended for use by one patient who is not accompanied by a medical attendant?
NFPA 99 defines Class B chambers as single-occupancy units designed for one patient without an inside attendant, which is the standard monoplace configuration.
