A nurse is explaining the purpose of blood tests for hypertension diagnosis to a client. Which parameter should the nurse indicate as essential in assessing kidney function?

A) This option is incorrect. Checking blood pressure once a week is insufficient for effective monitoring, as it may not provide a comprehensive view of blood pressure trends.

B) This option is incorrect. Using the arm with the highest blood pressure reading consistently is not recommended. Blood pressure should be measured in the arm with the higher reading only if there

is a significant difference between the arms.

C) This option is incorrect. To obtain accurate blood pressure readings, the client should rest for at least 5 minutes in a comfortable seated position with their feet flat on the floor and arms supported at heart level. Crossing the legs may affect blood flow and accuracy of the reading.

D) Correct answer. Recording blood pressure readings and any symptoms in a journal is essential for effective self-monitoring. It provides valuable information for the healthcare provider to assess blood pressure control and make necessary adjustments to the treatment plan.

A) This option is incorrect. While severe headaches and visual disturbances can occur in hypertensive crises, they are not typical symptoms of hypertension in its early stages.

B) This option is incorrect. Chest pain and shortness of breath are not common symptoms of hypertension.

C) Correct answer. Hypertension is often asymptomatic in its early stages, earning it the nickname "silent killer." Occasionally, clients may experience nosebleeds and fatigue, but many individuals with hypertension do not exhibit any noticeable symptoms.

D) This option is incorrect. Palpitations and increased heart rate are not typical symptoms of hypertension. These may be indicative of other cardiac conditions.
