You are palpating the abdomen and feel a small mass. Which of the following would you do next?

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: C

Rationale: The most likely pathologic process in this scenario is degenerative. The history provided includes chronic intermittent neck pain that worsened after a specific activity (wallpapering) but resolved with rest. The patient's age (47 years old) is also suggestive of degenerative changes in the spine. Additionally, the use of over-the-counter medications to manage the pain points towards a chronic condition such as degenerative changes in the cervical spine, possibly cervical spondylosis or osteoarthritis. There is no mention of any infectious symptoms, trauma, or neoplastic features in the presentation.

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: Perseveration is a speech pattern characterized by repeating a particular word, phrase, or topic excessively, even when it is no longer relevant to the conversation. In this scenario, the patient's repetitive use of the word "largely" to the point of distraction is indicative of perseveration. This can be a symptom of various neurological or psychiatric conditions, highlighting the importance of recognizing and addressing this speech pattern during the patient interview.

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: D

Rationale: Option D, "Psychosocial reasons may cause this condition," is true. Vaginismus is a condition characterized by involuntary contractions of the muscles around the vaginal entrance, which can make sexual intercourse painful, difficult, or impossible. In many cases, this condition is linked with psychological factors such as anxiety, fear, past trauma, or relationship issues. These psychological factors can lead to the muscles tightening up in anticipation of pain or discomfort during intercourse, hence causing vaginismus. With appropriate psychological interventions like counseling, therapy, or relaxation techniques, individuals experiencing vaginismus can often overcome the condition and engage in pain-free intercourse.

Correct Answer: B

Rationale: Dakota's presentation of a rash with small, bright red marks that do not fade when pressed (non-blanching) along with a slight fever raises concern for a serious condition such as meningococcal infection. Non-blanching rashes, especially when associated with fever, can be a sign of meningococcal sepsis, a life-threatening condition that requires urgent medical attention. Admission to the hospital is warranted for close monitoring, further evaluation, and initiation of appropriate treatment if needed. It is important to err on the side of caution in such cases to ensure the best possible outcome for the patient.

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.

Correct Answer: A

Rationale: Glaucoma is a progressive optic neuropathy characterized by changes to the optic nerve head. One of the hallmark features seen on funduscopic examination in glaucoma is an increased cup-to-disc ratio. This refers to the ratio of the size of the optic cup (depression in the center of the optic nerve head) to the size of the optic disc (the pinkish-orange area around the cup). In glaucoma, there is typically an enlargement of the cup relative to the disc due to damage of the retinal ganglion cell axons. This change is often associated with thinning of the neuroretinal rim and loss of nerve fibers.
