Correct Answer: C

Rationale: When the uvula deviates to one side upon touching the soft palate, it indicates a dysfunction of the vagus nerve (CN X) on the side toward which the uvula deviates. In this case, the uvula deviates to the left, suggesting a lesion affecting the left CN X. This is because the palate and uvula are innervated by the vagus nerve (cranial nerve X), and damage to this nerve may result in an asymmetric elevation or deviation of the uvula upon stimulation. Therefore, a CN X lesion on the left side is the most likely explanation for the observed deviation of the uvula in this scenario.

Correct Answer: A

Rationale: When palpating the abdomen and feeling a small mass, the next step would be to perform an ultrasound. Ultrasound imaging is a non-invasive and reliable way to further evaluate the size, location, and characteristics of the mass. It can provide valuable information to determine the nature of the mass, such as whether it is a cyst, a solid mass, or another type of abnormality. This imaging modality can help guide further management and treatment decisions, such as determining if surgery is necessary or if further monitoring is required. Ultrasound is a safe and commonly used tool in assessing abdominal masses, making it an appropriate next step in this scenario.

Correct Answer: B

Rationale: Asymmetric blood pressures (BPs) refer to a significant difference in blood pressures between the two arms. This is commonly seen in conditions like congenital narrowing of the aorta, also known as coarctation of the aorta. In this condition, there is a localized narrowing of the aorta, leading to higher blood pressure in the upper extremities compared to the lower extremities. This results in a significant asymmetry in blood pressure readings between the arms. It is crucial to identify this sign as it can have important diagnostic and treatment implications.

Correct Answer: D

Rationale: When a woman over the age of 40 presents with a breast mass, the risk of the mass being cancerous is around 40%. This risk is higher in older women compared to younger women. It is important for Mrs. Patton to undergo further evaluation, which may include imaging tests, a biopsy, and consultation with a specialist to confirm the diagnosis and determine the appropriate treatment. It is crucial to address breast masses promptly to ensure timely management and optimal outcomes.

Correct Answer: D

Rationale: In a patient with emphysema, lung hyperinflation can make it difficult to hear heart sounds anteriorly. Listening posteriorly, especially between the scapulae, can often provide a clearer auscultation of the heart sounds due to reduced interference from lung sounds. The posterior approach can also help avoid any abdominal sounds that might obscure the cardiac sounds when auscultating in the epigastrium. It is important to make sure the patient is in a comfortable position for better examination, and in this case, listening posteriorly would be the best choice for assessing heart sounds in a patient with emphysema in exacerbation.
