Physical Assessment Practice Questions

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: D

Rationale: The given symptoms of distant air sounds, late inspiratory crackles in both lower lobes, distant S1 and S2 heart sounds, and an S3 heart sound heard over the apex are all characteristic findings of left-sided heart failure. Distant air sounds and late inspiratory crackles indicate pulmonary congestion due to fluid accumulation in the lungs as a result of left-sided heart failure. The distant heart sounds and presence of an S3 are signs of left ventricular dysfunction. In contrast, pneumonia would typically present with more localized abnormal breath sounds and other symptoms such as fever and productive cough. Chronic obstructive pulmonary disease (COPD) would manifest with prolonged expiratory phase and wheezing, not late inspiratory crackles. Pleural pain is typically associated with sharp chest pain exacerbated by breathing movements, and it does not explain the constellation of symptoms described in this case. Therefore, the most likely diagnosis based on the provided symptoms

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: 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: C

Rationale: Diminished radial pulses may be seen in patients with arterial emboli. Arterial emboli are blood clots that travel through the bloodstream and get lodged in a blood vessel, blocking blood flow to a certain area. When an embolus affects the arteries supplying the arm, it can lead to diminished pulses in the affected arm, such as the radial pulse in the wrist. This diminished pulse is due to decreased blood flow to the area beyond the blockage caused by the embolus. This distinguishes arterial emboli from the other options listed, as aortic insufficiency, hyperthyroidism, and early "warm" septic shock typically do not cause isolated diminished radial pulses.
