A nurse is explaining the importance of an electrocardiogram (ECG) in the diagnosis of hypertension. Which statement should the nurse include in the discussion?
"An ECG helps determine the extent of blockages in your arteries caused by hypertension."
"ECG results are used to identify any enlargement or abnormalities in your heart due to hypertension."
"An ECG is essential in diagnosing kidney damage, which is a common complication of hypertension."
"ECG results provide information on the levels of sodium and potassium in your blood, which may be affected by hypertension."
The Correct Answer is B
A) This option is incorrect. While hypertension is a risk factor for cardiovascular diseases like atherosclerosis, an ECG primarily assesses the heart's electrical activity, not arterial blockages.
B) Correct answer. An ECG is essential in diagnosing and assessing heart abnormalities, such as left ventricular hypertrophy, which can result from the strain caused by hypertension.
C) This option is incorrect. An ECG is not directly used to diagnose kidney damage. Blood tests like creatinine and BUN are more specific for assessing kidney function in the context of hypertension.
D) This option is incorrect. An ECG does not provide information on blood levels of sodium and potassium. Blood tests are used for evaluating electrolyte levels, not ECG results.

Correct Answer is C
Explanation
Rationale:
A) This statement is incorrect. Hypertension is characterized by elevated blood pressure levels, not low blood pressure levels.
B) This statement is incorrect. Regular screenings for hypertension are essential, even in the absence of symptoms, to detect and manage the condition early.
C) Correct answer. Hypertension is often asymptomatic in its early stages, which makes routine screenings crucial for timely diagnosis and intervention.
D) This statement is incorrect. While a family history of hypertension is a risk factor, there are other non-modifiable and modifiable risk factors that can contribute to the development of hypertension.
Correct Answer is B
Explanation
A) This option is incorrect. Liver enzymes (ALT and AST) are not relevant to assessing kidney function or hypertension-related kidney damage.
B) Correct answer. A renal function panel typically includes creatinine and BUN levels, as they are essential markers used to evaluate kidney function in the context of hypertension.
C) This option is incorrect. Blood glucose and HbA1c levels are related to diabetes assessment and management, not kidney function in hypertension.
D) This option is incorrect. Prothrombin time (PT) and international normalized
ratio (INR) are coagulation tests used to evaluate blood clotting, not kidney function or hypertension-related kidney damage.
