An infant with hydrocele is seen in the clinic for a follow-up visit at 1 month of age. The scrotum is smaller than it was at birth, but fluid is still visible on illumination. Which of the following actions is the physician likely to recommend?

Correct Answer: C

Rationale: A hydrocele is a collection of fluid in the scrotum that results from a patent tunica vaginalis. Illumination of the scrotum with a pocket light demonstrates the clear fluid. In most cases, the fluid reabsorbs within the first few months of life and no treatment is necessary. Massaging the groin area (Choice A) is not recommended as it will not help in the resolution of the hydrocele. Referral to a surgeon (Choice B) is not necessary at this stage since hydroceles often resolve on their own in infants. Keeping the infant in a flat, supine position (Choice D) does not aid in the reabsorption of fluid and is not a recommended intervention for hydrocele management.

Correct Answer: C

Rationale: To diagnose pancreatitis, testing amylase and lipase levels is crucial. Amylase and lipase are enzymes produced by the pancreas that help digest carbohydrates and lipids. In pancreatitis, these enzymes are released in high amounts into the bloodstream due to pancreatic inflammation or damage. Elevated levels of amylase and lipase in blood tests strongly indicate pancreatitis. Choice A, CK and Troponin, are cardiac markers used in diagnosing heart conditions like myocardial infarction, not pancreatitis. Choice B, BUN and Creatinine, are kidney function tests, not specific to pancreatitis. Choice D, HDL and LDL Cholesterol Levels, are lipid profile tests used to assess cardiovascular health, not for diagnosing pancreatitis.

Correct Answer: C

Rationale: Penetrating wounds that leave an object behind may have damaged important blood vessels. Removing the object may lead to significant bleeding. The correct approach is to gently wrap the wound with the object in place to help control bleeding and prevent further injury. The patient should be taken promptly to the nearest emergency room where healthcare professionals can safely and appropriately remove the object and provide necessary treatment. Choice A is incorrect because removing the pencil without proper medical evaluation can worsen the injury. Choice B is incorrect because pulling out the object can cause additional damage and bleeding. Choice D is incorrect because giving aspirin without knowing the extent of the injury and causing potential drug interactions can be harmful.

Correct Answer: C

Rationale: Pneumonia is the most common complication of chest wall injury. Chest wall trauma can lead to impaired lung function, making patients more susceptible to pneumonia due to reduced ability to clear secretions and impaired breathing. While hemothorax and pneumothorax are potential complications of chest wall injury, pneumonia is more commonly encountered. Atelectasis, although a common pulmonary complication, is not typically the most common complication seen in chest wall injuries.

Correct Answer: C

Rationale: Subdural hemorrhages are more common in the elderly due to cerebral atrophy resulting from the natural aging process. This atrophy can lead to the stretching of bridging veins, making them more fragile and prone to tearing even with minor trauma. While increased anticoagulant use and a higher risk of falls are common in the elderly, brain atrophy plays a more direct role in the increased incidence of subdural hemorrhages. Inconsistent caregiving, on the other hand, is not a direct cause of subdural hemorrhages but may impact the overall management and outcome of such cases.
