Which of the following conditions involves a tight prepuce which, once retracted, cannot be returned?

Correct Answer: B

Rationale: Paraphimosis is a condition where the foreskin is retracted behind the glans penis and cannot be returned to its original position. This can lead to swelling and constriction of the penis, causing pain and potential damage to the tissue due to decreased blood flow. Phimosis (Choice A) refers to a tight prepuce that cannot be retracted over the glans penis. Balanitis (Choice C) is inflammation of the glans penis, often associated with poor hygiene or infections. Balanoposthitis (Choice D) refers to inflammation of both the glans penis and the foreskin.

Correct Answer: B

Rationale: Ascites is the abnormal accumulation of fluid in the abdominal cavity. When ascites is present, dullness is typically heard on percussion due to the fluid in the abdomen. This dullness does not shift with changes in the patient's position. Therefore, the finding of dullness which remains despite a change in position would argue for the presence of ascites. The other choices (A, C, D) describe findings that are more consistent with gaseous distention rather than ascites.

Correct Answer: A

Rationale: Inspiratory splitting of S occurs due to the normal physiological delay in the closure of the aortic and pulmonic valves during inspiration. During inspiration, the negative intrathoracic pressure leads to increased venous return to the right side of the heart, causing a slight delay in the closure of the pulmonic valve. This results in the aortic valve closing first, followed by the closure of the pulmonic valve, leading to the splitting of S during inspiration.

Correct Answer: B

Rationale: The information provided - "The patient had a stent placed in the left anterior descending artery (LAD)" - is related to a medical procedure, specifically a surgical intervention involving the placement of a stent in a coronary artery. This information falls under the category of surgeries because it describes a surgical treatment to address a cardiovascular issue. It does not pertain to adult illnesses, obstetrics/gynecology, or psychiatric conditions, making option B the most appropriate category for this information.

Correct Answer: C

Rationale: The next step would be to discuss the physical therapy plan with Mr. Larson. It is important to communicate openly with him, explain the recommendation for physical therapy, and ensure that he understands and agrees with the plan before proceeding further. This allows for any questions or concerns to be addressed, and ensures that the treatment plan is tailored to his needs and preferences. By discussing the plan with Mr. Larson first, you can also provide him with the opportunity to ask any questions and actively involve him in his own care, which can lead to better compliance and outcomes.

Correct Answer: B

Rationale: The clinical presentation described in the question is consistent with Candida vaginitis, also known as vaginal yeast infection. Candida vaginitis typically presents with a thick, white, curdy discharge that can be visualized on examination. The low pH of 1 is characteristic of Candida infection. The negative KOH whiff test and absence of an unusual smell help differentiate Candida vaginitis from other types of vaginitis.

Correct Answer: C

Rationale: Fibromyalgia is a chronic pain syndrome characterized by widespread musculoskeletal pain, fatigue, and multiple tender points on palpation, especially in the neck, shoulders, back, and hips. The patient's symptoms of widespread pain and tenderness at specific points on the muscles without arthritis, joint swelling, or limitation in range of motion are consistent with fibromyalgia. Fibromyalgia is often associated with poor sleep quality, morning stiffness, and fatigue, which the patient in the case provided experiences. Other conditions like rheumatoid arthritis, osteoarthritis, or polymyalgia rheumatica would typically present differently with specific joint involvement, swelling, and additional systemic symptoms, which are not seen in this patient.

Correct Answer: C

Rationale: Epistaxis, also known as a nosebleed, should be considered in a patient complaining of coughing up blood along with a history of smoking. Epistaxis can sometimes lead to blood trickling down the throat and being coughed up. It is important to consider this differential diagnosis, especially in patients with risk factors such as smoking. Intestinal bleeding (choice A) has a different presentation and cause compared to epistaxis. Hematoma of the nasal septum (choice B) is unlikely to cause coughing up blood. Bruising of the tongue (choice D) is also less likely to be the cause of hemoptysis in this case.

Correct Answer: C

Rationale: A right homonymous hemianopsia refers to a visual field defect in which the patient is unable to see objects in the right half of the visual field in both eyes. In the case described, the stroke patient is unable to see your fingers on his entire right side with either eye covered, which is consistent with a right homonymous hemianopsia. This type of visual field defect typically occurs as a result of damage to the optic tract or optic radiation on one side of the brain, which affects the processing of visual information from the opposite visual field. It is important to note that bitemporal hemianopsia, right temporal hemianopsia, and binasal hemianopsia involve different patterns of visual field loss and are not fitting descriptions for the presented scenario.
