A patient with longstanding COPD was told by another practitioner that his liver was enlarged and this needed to be assessed. Which of the following would be reasonable to do next?

Correct Answer: D

Rationale: The correct answer is D: Obtain an ultrasound of the liver. This is the most appropriate next step to assess the patient's enlarged liver in the context of COPD. Ultrasound can provide detailed images of the liver to identify potential causes of enlargement, such as fatty liver disease or liver cirrhosis. Percussing the lower border (Choice A) or measuring the span of the liver (Choice B) may provide some information but are less specific and may not identify the underlying cause. Ordering a hepatitis panel (Choice C) would focus only on viral hepatitis as a potential cause, while an ultrasound can provide a broader evaluation of liver structure and function.

Correct Answer: C

Rationale: The correct answer is C: Stop aspirin and begin apixaban 5 mg twice a day. The rationale is that for stroke risk reduction in nonvalvular atrial fibrillation, anticoagulation therapy with direct oral anticoagulants (DOACs) like apixaban is preferred over antiplatelet therapy like aspirin. DOACs have been shown to be more effective in reducing stroke risk with a lower bleeding risk compared to warfarin. Choice A is incorrect as aspirin alone is not sufficient for stroke prevention in atrial fibrillation. Choice B is incorrect as warfarin has more monitoring requirements and potential drug interactions compared to DOACs like apixaban. Choice D is incorrect as aspirin and apixaban together are not recommended due to increased bleeding risk.

Correct Answer: A

Rationale: Rationale: The correct answer is A: Supraspinatus. This muscle is responsible for initiating abduction movement at the shoulder joint. It is located on the top of the shoulder blade and assists in lifting the arm away from the body. The other choices, B: Infraspinatus, C: Levator scapulae muscle, and D: Subscapularis, are not involved in initiating abduction movement at the shoulder. Infraspinatus is responsible for external rotation, Levator scapulae muscle elevates the scapula, and Subscapularis assists in internal rotation of the shoulder joint.

Correct Answer: A

Rationale: The correct answer is A: Papilledema. Diabetic retinopathy is a microvascular complication of diabetes that primarily affects the retina's blood vessels. Papilledema, which is optic disc swelling due to increased intracranial pressure, is not a typical finding in diabetic retinopathy. Dot and blot hemorrhages, microaneurysms, and cotton wool spots are commonly seen in diabetic retinopathy due to retinal vessel damage and ischemia. Papilledema is more associated with conditions like intracranial hypertension or optic neuritis.

Correct Answer: B

Rationale: The correct answer is B: Chest pain and pleuritic breathing. This indicates possible complications like pleurisy or pleural effusion, requiring further evaluation. A: Persistent cough with sputum production is common in pneumonia. C: Shortness of breath is a typical symptom of pneumonia. D: Fever and chills are also common in pneumonia. However, chest pain and pleuritic breathing are more indicative of potential complications that may require immediate attention.

Correct Answer: C

Rationale: The correct answer is C because cultural humility emphasizes recognizing power imbalances and fostering interpersonal sensitivity through partnerships with and learning from patients. This approach encourages self-awareness, openness, and willingness to engage in respectful dialogues. Option A is incorrect because cultural humility is not solely achieved through professional development courses. Option B is incorrect as anyone, regardless of their background, can practice cultural humility. Option D is incorrect as cultural humility does consider the impacts of structural factors on health disparities, including biological, socioeconomic, and racial influences.

Correct Answer: D

Rationale: The correct answer is D: Repeat PSA in 6 months. In this case, the patient's PSA levels have decreased from 12 ng/mL to 10 ng/mL after treatment with tamsulosin and removal of the Foley catheter. Given the improvement in PSA levels, it is reasonable to monitor for further changes before considering invasive procedures like transrectal ultrasound and biopsy (choice A), which may not be necessary at this time. Empiric finasteride (choice B) is not indicated as the patient is already responding well to tamsulosin. A bone scan (choice C) is not necessary at this stage as there are no indications of metastasis. Therefore, repeating the PSA in 6 months allows for continued monitoring of the patient's prostate health without subjecting him to unnecessary procedures.

Correct Answer: B

Rationale: The correct answer is B: Lung cancer. The patient's symptoms of chronic smoking, persistent cough, and weight loss are concerning for malignancy. Lung cancer is a common consequence of long-term smoking and can present with these symptoms. Chronic bronchitis (A) typically presents with cough and mucus production but not necessarily weight loss. Emphysema (C) is characterized by shortness of breath and is less likely to cause weight loss. Asthma (D) usually presents with wheezing and shortness of breath, not typically weight loss.

Correct Answer: A

Rationale: The correct answer is A: Provide positive pressure ventilation with supplemental oxygen. This is the most appropriate action as the patient is cyanotic, responsive to painful stimuli, and exhibiting stridorous respirations, indicating potential airway compromise. Providing positive pressure ventilation with supplemental oxygen can help improve oxygenation and support the patient's breathing. Summary of other choices: B: Obtaining vital signs is important, but in this urgent situation, addressing the airway and breathing takes precedence. C: Contacting medical direction may delay essential treatment. Immediate intervention is crucial in this scenario. D: Applying a pulse oximeter can provide valuable information, but administering oxygen and ensuring adequate ventilation should be the priority in a patient with compromised breathing.
