Physical Assessment Practice Questions

Correct Answer: D

Rationale: The group of lymph nodes that lie just behind the sternocleidomastoid muscles bilaterally are known as the posterior cervical lymph nodes. These lymph nodes are part of the superficial cervical lymph node chain, which is involved in draining lymph from the head and neck region. In the case described, the presence of sore throat, fever, and enlarged tonsils with exudates suggests a likely upper respiratory tract infection or tonsillitis, leading to the enlargement of the nearby lymph nodes. The posterior cervical lymph nodes are commonly examined in cases of upper respiratory infections and tonsillitis due to their proximity to the area of infection and inflammation.

Correct Answer: A

Rationale: The raised, dark red rash that does not blanch when pressed on, typically known as erythema nodosum, is a common skin manifestation of systemic lupus erythematosus (SLE). Given Mrs. Hill's history of SLE, it is likely that her rash is related to her autoimmune condition rather than an exposure to a chemical or an allergic reaction. It is important for her to discuss this new symptom with her healthcare provider to ensure appropriate management and monitoring of her lupus.

Correct Answer: A

Rationale: When crackles, wheezes, or rhonchi clear with a cough, it is suggestive of bronchitis. Bronchitis is inflammation of the bronchial tubes, often due to a viral infection, leading to the production of excess mucus. The characteristic sounds such as crackles, wheezes, or rhonchi can be heard on auscultation due to the presence of mucus in the airways. The act of coughing helps to clear the mucus from the airways, resulting in the temporary resolution of these abnormal sounds. In contrast, asthma, cystic fibrosis, and heart failure are not typically associated with crackles, wheezes, or rhonchi that clear with a cough.

Correct Answer: B

Rationale: The dullness in the last intercostal space in the anterior axillary line on the left side with a deep breath is suggestive of splenomegaly. However, this finding alone is not definitive for an enlarged spleen. The size of the spleen can vary, and further examination is required to confirm if the spleen is indeed enlarged. Therefore, Option B is the most appropriate choice as it indicates that the spleen is possibly enlarged, and close attention should be paid to further examination to confirm its status. Further workup, such as imaging studies or blood tests, may be necessary to evaluate the size and function of the spleen in this case.

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.
