A nurse is screening a group of people at a community health event for hypertension. Which patient will the nurse identify is at risk for hypertension?

A. "Has anyone in your family ever experienced symptoms similar to yours?":
This question aims to gather information about potential familial illnesses or infections but does not specifically address the possible etiology of human immunodeficiency virus (HIV). While HIV can be transmitted vertically from mother to child, asking about family members' symptoms is less directly relevant to the assessment of HIV exposure.

B. "How many alcoholic drinks do you typically consume in a week?":
This question assesses the patient's alcohol consumption habits and is important for evaluating overall health and potential risk factors for various conditions. However, it does not directly address the possible etiology of human immunodeficiency virus (HIV). Alcohol consumption may affect immune function but is not a primary indicator of HIV exposure.

C. "To the best of your knowledge, are your immunizations up to date?":
This question is aimed at assessing the patient's immunization status and is essential for preventive healthcare. However, it does not directly address the possible etiology of human immunodeficiency virus (HIV). Immunizations primarily protect against infectious diseases caused by bacteria or viruses other than HIV.

D. "Have you recently had unprotected intercourse with a new partner?":
This question directly addresses behaviors that could lead to HIV transmission. Unprotected sexual intercourse with a new partner is a significant risk factor for acquiring HIV, as the virus can be transmitted through sexual contact with an infected individual. Asking about recent sexual activity helps identify potential exposure to HIV and informs appropriate testing and counseling.

A. Having the primary provider prescribe a CT:
Prescribing a CT scan is not the initial action for assessing nonpalpable pedal pulses. CT scans are typically used for imaging purposes and are not the primary diagnostic tool for assessing peripheral pulses.

B. Apply a tourniquet for 3 to 5 minutes and then reassess:
While applying a tourniquet may increase the visibility of pulses in some cases, it is not the recommended method for assessing pedal pulses, especially if they are nonpalpable. Tourniquet use carries risks, such as tissue damage or ischemia, and is not a standard practice for assessing pulses.

C. Elevate the extremity and attempt to palpate the pulses:
Elevating the extremity may improve blood flow and make pulses easier to palpate, but if the pulses are nonpalpable, simply elevating the extremity may not be sufficient for assessment. Additionally, palpation alone may not accurately detect pulses in some cases.

D. Use the doppler ultrasound to detect pedal pulses:
This is the most appropriate action. Doppler ultrasound is a non-invasive diagnostic tool commonly used to assess peripheral pulses, especially when they are nonpalpable. It uses sound waves to detect blood flow and can provide accurate information about the presence and strength of pedal pulses. Using a doppler ultrasound can help confirm the status of pedal pulses and guide further management.
