Physical Assessment Practice Questions

Correct Answer: A

Rationale: In order to listen carefully for S splitting, one should use the diaphragm with light pressure over the 2nd right intercostal space. S splitting refers to a split of the second heart sound (S2) into its two components - A2 and P2. The A2 component is normally heard as the main heart sound when the aortic valve closes, and the P2 component is heard when the pulmonic valve closes. By placing the diaphragm lightly over the 2nd right intercostal space, one can best auscultate the aortic area and listen for the timing and splitting of the S2 components. Using the bell or applying firm pressure may not allow for optimal detection of S splitting in this specific case.

Correct Answer: D

Rationale: Audiometric testing is a very sensitive method for detecting hearing loss. It involves a series of tests that measure a person's ability to hear sounds at various frequencies and volumes. These tests can detect even subtle changes in hearing ability and provide detailed information on the type and degree of hearing loss. The whisper test and finger rub test are basic screening tests and are not as sensitive or comprehensive as audiometric testing. The tuning fork test is also used in evaluating hearing loss, but it is not as accurate or sensitive as audiometric testing. Overall, audiometric testing is considered the gold standard for diagnosing hearing loss due to its high sensitivity and ability to provide detailed information on the individual's hearing capabilities.

Correct Answer: C

Rationale: Marion's presentation of back pain associated with constipation and urinary retention is concerning for cauda equina syndrome. Cauda equina syndrome is a rare but serious condition caused by the compression of the bundle of nerves at the bottom of the spinal cord, known as the cauda equina. This compression can result in a variety of symptoms, including back pain, sciatica, changes in bowel and bladder function (such as constipation and urinary retention), as well as lower extremity weakness or numbness.

Correct Answer: A

Rationale: According to American Cancer Society recommendations, a woman should undergo a screening breast examination by a skilled clinician every year. Regular breast exams help in early detection of breast cancer, which can significantly improve outcomes and treatment options. Annual screenings are crucial in monitoring changes in breast health and detecting any abnormalities at the earliest stage possible. Therefore, it is advised that women follow this guideline to prioritize their breast health and well-being.

Correct Answer: B

Rationale: Research studies have shown that for every increment of 20 mm Hg in systolic blood pressure and 10 mm Hg in diastolic blood pressure, the cardiovascular risk approximately doubles. Therefore, the cardiovascular risk increases by 50% for each increment of 20 mm Hg systolic and 10 mm Hg diastolic in blood pressure. This underlines the importance of maintaining healthy blood pressure levels to reduce the risk of cardiovascular diseases.
