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: A

Rationale: The correct answer is A: A palpable "notch" along its edge. This supports an enlarged kidney over the spleen because the kidney has a concave shape with a notch where the renal vessels enter. This notch is palpable in an enlarged kidney. Choice B is incorrect because the inability to push fingers between the mass and the costal margin is indicative of a spleen, which is a solid organ located close to the ribs. Choice C is incorrect as normal tympany over the area suggests gas-filled structures like the stomach or intestines, not a solid organ like the kidney or spleen. Choice D is incorrect as the ability to push fingers medial and deep to the mass would be more typical of an enlarged spleen, which can displace other organs medially due to its size.

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 because in Munchausen syndrome by proxy, the patient only exhibits symptoms under the direct care or supervision of the abuser. This is because the abuser intentionally causes or fabricates symptoms in the victim to gain attention or sympathy. In contrast, the other choices are incorrect. A is incorrect because the injury is inflicted by the abuser, not self-inflicted by the patient. C is incorrect as the caregiver is the one perpetrating the abuse. D is incorrect because the abuser is often overly involved and manipulative, rather than inattentive and uncaring.

Correct Answer: C

Rationale: The correct answer is C: Regularly irregular rhythm. This is the appropriate documentation for Ms. Wright's presentation as her pulse demonstrates a pattern of irregularity with every fourth beat sounding different. This indicates a regularly irregular rhythm, where there is a discernible pattern to the irregularity. Rationale: 1. Regular rate and rhythm (Choice A) is incorrect as Ms. Wright's palpitations and the irregularity in her pulse indicate an irregular rhythm. 2. Irregularly irregular rhythm (Choice B) is incorrect as this term is used to describe arrhythmias like atrial fibrillation, which do not have a discernible pattern of irregularity. 3. Bradycardia (Choice D) is incorrect as it refers to a slow heart rate, which is not the primary concern in this scenario where the focus is on the irregular rhythm. In summary, the correct choice (C) accurately describes the specific irregular pattern observed in Ms. Wright's pulse, distinguishing it from
