Correct Answer: C

Rationale: The correct answer is C: Cells die. In Alzheimer's disease, there is a progressive degeneration of brain cells, leading to cell death. This results in a loss of important brain functions such as memory, cognition, and eventually, bodily functions. The atrophy of the brain stem (choice A) is not a characteristic feature of Alzheimer's. Fluid buildup (choice B) is not a primary mechanism of the disease. Tissue swelling (choice D) is not typically associated with the progression of Alzheimer's; rather, there is a gradual loss of brain tissue due to cell death.

Correct Answer: B

Rationale: The correct answer is B: Disseminated intravascular coagulation (DIC). In DIC, there is widespread activation of coagulation leading to consumption of clotting factors, resulting in prolonged PT and aPTT, low fibrinogen levels, and elevated D-dimer. This pattern matches the laboratory findings in the patient. In liver cirrhosis (choice A), there is a decrease in clotting factors synthesis, leading to prolonged PT but not aPTT. Hemophilia A (choice C) is a genetic disorder that affects specific clotting factors, typically leading to prolonged aPTT but not PT. Vitamin K deficiency (choice D) impairs the synthesis of clotting factors, leading to prolonged PT but not aPTT and low levels of factors II, VII, IX, and X.

Correct Answer: A

Rationale: The correct answer is A: Empiric antibiotic therapy directed against common pathogens. This is recommended for managing PID because it helps treat the infection and prevent complications. Antibiotics target the underlying bacterial infection causing PID. Surgical exploration (B) is not the initial treatment for PID. Hormonal therapy (C) is not indicated for PID management. Symptomatic treatment with NSAIDs (D) can help with pain but does not address the infection itself.

Correct Answer: B

Rationale: The primary reason for surgical repair of myelomeningocele is to correct the neurologic defect. This is because myelomeningocele is a type of neural tube defect where the spinal cord and its protective covering do not close properly. Surgical repair aims to close the opening in the spinal cord to prevent further damage, improve neurological function, and reduce the risk of complications such as paralysis and infection. The other choices are incorrect as they are not the primary goal of the surgery. Preventing infection (Choice A) is important but not the primary reason. Seizure disorders (Choice C) and hydrocephalus (Choice D) may be associated complications but are not the main purpose of the surgical repair.

Correct Answer: C

Rationale: The correct answer is C: Pancreas. The pancreas is responsible for producing digestive enzymes and bicarbonate-rich pancreatic juice. It secretes enzymes like amylase, lipase, and protease to break down carbohydrates, fats, and proteins in the small intestine. The bicarbonate-rich juice helps neutralize stomach acid. The liver (A) produces bile stored in the gallbladder (B), which aids in fat digestion. The spleen (D) is involved in immune function and blood filtration, not digestive enzyme production.
