Assessment Tools & Diagnostics Hemakshi Chohan Walden University NURS 6512N, Health Assessment June 10, 2019 Introduction There is a vast array of diagnostic testing available to an advanced practice nurse when seeking to understand a patient’s condition. What makes each diagnostic test and assessment tool vary are the different factors that affect the validity and reliability of the results of these tests. Thus, it will be imperative for a nurse to look in deeper ways and to identify these factors in order to pick the right tool and accurately interpret the result. How the Mammogram Testing is Used in Health Care One of the sure ways that a mammography can be used as a diagnostic tool is when a patient presents with a lump in their breast that is a palpable mass and has nipple discharge. In order to identify that this lump is indeed an abnormal lump or to rule out a benign fibrous growth, a diagnostic mammogram will provide differnet views to assess the features of the mass and to pin point its exact location in a breast tissue. This could include a spot compression, magnification, exaggerated craniocaudal to the medial or lateral side, tangential, and a ninety degree lateral view (Dains, Baumann & Scheibel, 2016). Because the density of the breast tissue
matters for identification, mammography is of less value in women younger than age thirty years of age. Another way to look at a mammogram is that it is an x-ray exam of the breast. It is used for women who have breast complaints and women who do not have complaints. It is highly efficient because the procedure allows for detection of cancers before palpation becomes a possibility. After a mammography shows a mass on the x-ray, a tissue sample can be removed for testing of cancer by a procedure called biopsy (Qin, White, Sabatino & Febo-Vazquez, 2018). Mammography usage began thirty years ago and in the past decade the technique has improved drastically (Qin et al., 2018). In fact today, high quality results can be obtained with a low radiation dose.
