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: B

Rationale: The history and physical examination findings in this case are most consistent with acute epididymitis. Acute epididymitis is characterized by inflammation and infection of the epididymis, which is a tubular structure located behind the testicle that stores and carries sperm. Common symptoms of acute epididymitis include pain and swelling in the scrotum, testicular pain, pain with urination, and sometimes penile discharge. The patient's symptoms of testicular and penile pain, as well as pain with urination, are classic for epididymitis. The severe tenderness at the superior pole of the left testicle and tenderness on palpation of structures superior to the testicle through the scrotal wall further support this diagnosis. In addition, the presence of white blood cells and bacteria on urine analysis is consistent with an infectious process like epididymitis.

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.
