NurseDive Free Nursing Practice Question
A nurse is explaining the pathophysiology of hypertension to a client. Which process is primarily responsible for elevated blood pressure in hypertension?
A. Vasodilation and increased sodium excretion
This option is incorrect. In hypertension, there is often vasoconstriction and increased sodium retention, leading to elevated blood pressure.
B. Activation of the renin-angiotensin-aldosterone system (RAAS)
Correct answer. Activation of the renin-angiotensin-aldosterone system (RAAS) is a key mechanism in hypertension. It leads to vasoconstriction and increased water and sodium retention, elevating blood pressure.
C. Decreased sympathetic nervous system activity
This option is incorrect. In hypertension, sympathetic nervous system activity is often increased, not decreased.
D. Enhanced nitric oxide production
This option is incorrect. In hypertension, there is reduced nitric oxide production, which contributes to arterial stiffness and elevated blood pressure.

Similar Questions
A nurse is assessing a client suspected of having hypertension. Which clinical manifestation may be present in the early stages of hypertension?
A. Severe headaches
This option is incorrect. Severe headaches are more commonly associated with hypertensive crises, not the early stages of hypertension.
B. Blurred vision
This option is incorrect. Blurred vision may occur in severe hypertension but is not a typical early-stage manifestation.
C. Chest pain
This option is incorrect. Chest pain may be related to other cardiovascular conditions but is not a common manifestation of early-stage hypertension.
D. Asymptomatic
Correct answer. Hypertension is often asymptomatic in its early stages, making routine screenings crucial for early detection.

A nurse is reviewing diagnostic tests for hypertension with a client. Which test directly measures blood pressure levels for 24 hours?
A. Electrocardiogram (ECG)
This option is incorrect. An electrocardiogram (ECG) measures electrical activity in the heart, not blood pressure levels.
B. Blood glucose test
This option is incorrect. A blood glucose test measures blood sugar levels, not blood pressure.
C. Ambulatory Blood Pressure Monitoring (ABPM)
Correct answer. Ambulatory Blood Pressure Monitoring (ABPM) is a diagnostic test that measures blood pressure levels at regular intervals over 24 hours, providing a comprehensive view of a client's blood pressure variations.
D. Renal function panel
This option is incorrect. A renal function panel assesses kidney function, not blood pressure levels.

A nurse is discussing complications of hypertension with a client. Which target organ damage is related to hypertensive retinopathy?
A. Heart
This option is incorrect. Heart complications of hypertension include heart failure, myocardial infarction, and arrhythmias.
B. Kidneys
This option is incorrect. Kidney complications of hypertension include nephrosclerosis and chronic kidney disease.
C. Brain
This option is incorrect. Brain complications of hypertension include stroke and transient ischemic attacks (TIA).
D. Eyes
Correct answer. Hypertensive retinopathy refers to damage to the blood vessels in the eyes due to hypertension, leading to vision problems and potential vision loss.
