A patient can develop Glomerulonephritis after a previous skin infection caused by which organism?

Here are the answers to your questions:

1. A patient can develop Glomerulonephritis after a previous skin infection caused by which organism?

   • Post-streptococcal glomerulonephritis is a well-known complication following infections, particularly skin infections (impetigo) or pharyngitis, caused by certain strains of Streptococcus.
   • The correct option is d.
   • Answer: $\boxed{\text{d. Streptococcus}}$

2. Diabetic foot ulcer can be classified under which complication of Diabetes Mellitus?

   • Diabetic foot ulcers are a chronic complication of diabetes. They result from a combination of neuropathy (a microvascular complication) and peripheral artery disease (a macrovascular complication). Given the options, "Chronic - Macro complication" is the most appropriate classification, as macrovascular disease significantly contributes to poor healing and tissue damage in these ulcers.
   • The correct option is b.
   • Answer: $\boxed{\text{b. Chronic - Macro complication}}$

3. The Nervous system has many divisions. The brain and the spinal cord falls under which division?

   • The nervous system is broadly divided into the Central Nervous System (CNS) and the Peripheral Nervous System (PNS). The brain and spinal cord constitute the Central Nervous System.
   • The correct option is b.
   • Answer: $\boxed{\text{b. Central Nervous System}}$

4. In a patient with meningitis, Kernig's sign is said to be positive if:

   • Kernig's sign is positive when the patient is lying supine, the hip is flexed to 90 degrees, and extension of the leg at the knee causes pain and resistance.
   • Option c describes Brudzinski's sign (passive flexion of the neck causes involuntary flexion of the hips and knees), not Kernig's sign. However, among the given options, option c is the only one that describes a recognized sign of meningeal irritation, despite being mislabeled as Kernig's.
   • The most plausible intended answer, despite the inaccuracy in describing Kernig's sign, is c.
   • Answer: $\boxed{\text{c. Patient moves one leg when the head is raised}}$
