A nurse is assessing a patient who is presented with flu-like symptoms. Assessment reveals the presence of fever, sore throat, enlarged neck lymphatic nodes. What assessment question addresses the possible etiology of human immunodeficiency virus?

Answer: D

Rationale:

A) A renal ultrasound: A renal ultrasound is not typically used to confirm a diagnosis of hypertension. While renal artery stenosis can contribute to hypertension in some cases, it is not the primary diagnostic test for hypertension.

B) A cardiac stress test: A cardiac stress test is not used to confirm a diagnosis of hypertension. It is primarily used to assess cardiovascular function and detect coronary artery disease or cardiac arrhythmias.

C) A manual blood pressure cuff: While manual blood pressure measurements can provide accurate readings, they are subject to potential inaccuracies due to factors such as observer bias and white coat syndrome. Therefore, they may not be the most reliable method for confirming a diagnosis of hypertension.

D) Ambulatory blood pressure measurement: Ambulatory blood pressure measurement involves obtaining multiple blood pressure readings over a 24-hour period using a portable monitor. It is considered the gold standard for diagnosing hypertension, as it provides a more comprehensive assessment of blood pressure variability and reduces the impact of white coat syndrome. Therefore, it is the preferred diagnostic test in this scenario to confirm whether the patient has hypertension outside of the clinical setting.

A. Drink purified water: While drinking purified water is important for preventing various waterborne diseases, it is not a preventive measure specifically targeted at hepatitis B virus (HBV) transmission. HBV is primarily transmitted through exposure to infected blood or body fluids, such as during unprotected sex, sharing needles, or from mother to child during childbirth. Drinking purified water does not protect against these modes of HBV transmission.

B. Avoid crowded, enclosed spaces: Avoiding crowded, enclosed spaces may reduce the risk of respiratory infections, but it does not specifically prevent HBV transmission. HBV is not transmitted through the air like respiratory viruses. Instead, it is spread through direct contact with infected blood or body fluids. While avoiding crowded spaces may be a general infection control measure, it is not a targeted preventive measure for HBV.

C. Complete the vaccination series: This is the correct preventive measure for HBV. The hepatitis B vaccine is highly effective in preventing HBV infection. It is administered as a series of shots, typically given in three doses over a period of several months. Completing the vaccination series provides long-term immunity against HBV infection and is recommended for all individuals, including travelers to regions where HBV is common. Vaccination not only protects the individual but also contributes to reducing the overall prevalence of HBV in the community.

D. Avoid sharing utensils: While avoiding sharing utensils can reduce the risk of transmitting certain infections, such as colds or flu, it is not specifically aimed at preventing HBV transmission. HBV is primarily transmitted through activities involving exposure to infected blood or body fluids, rather than through sharing utensils. While practicing good hygiene and avoiding behaviors that may result in exposure to blood or body fluids are important preventive measures for HBV, completing the vaccination series is the most effective way to prevent infection.
