Paralysis of all or part of the trunk, legs, and pelvic organs is referred to as:

Correct Answer: C

Rationale: The correct answer is C: Paraplegia. Paraplegia refers to the paralysis of the lower half of the body, including both legs and often the trunk and pelvic organs. This term specifically indicates paralysis below the waist. Hemiplegia (A) refers to paralysis on one side of the body, not the trunk and legs. Tetraplegia (B) is paralysis of all four limbs and the trunk, not specifically the trunk, legs, and pelvic organs. Hemiparesis (D) is weakness on one side of the body, not a complete paralysis of the trunk, legs, and pelvic organs.

Correct Answer: C

Rationale: The correct answer is C: Dopamine. Parkinson's disease is primarily caused by the loss of dopamine-producing neurons in the brain. Dopamine is crucial for controlling movement, mood, and cognition. Serotonin (A) is not directly related to Parkinson's. Adrenaline (B) is involved in the fight-or-flight response, not Parkinson's. GABA (D) is an inhibitory neurotransmitter, not typically associated with Parkinson's disease.

Correct Answer: B

Rationale: The correct answer is B: Brudzinski sign. This sign is used to diagnose meningitis because it involves the involuntary flexion of the hips and knees when the neck is flexed. This reflex is indicative of meningeal irritation and is a classic sign of meningitis. A: Homan's sign is used to assess for deep vein thrombosis, not meningitis. C: Startle reflex is a normal response to a sudden unexpected stimulus, not specific to meningitis. D: Anterior drawer test is used to assess for ligamentous instability in the knee, not related to meningitis.

Correct Answer: A

Rationale: Rationale for Correct Answer (A): I. Epilepsy can have a genetic predisposition, as certain genetic factors can increase the likelihood of developing epilepsy, making statement I true (T). II. Old age is indeed a risk factor for Parkinson's disease, as the incidence of the disease increases with age, making statement II true (T). Therefore, the correct answer is A (TT). Summary of Incorrect Choices: B: FT - This choice is incorrect because both statements I and II are true. C: TF - This choice is incorrect because statement I is true (T) and statement II is also true (T). D: FF - This choice is incorrect because both statements I and II are true.

Correct Answer: A

Rationale: The correct answer is A: Apply warm blankets & continue oxygen as prescribed. Shivering after surgery indicates the patient is cold due to anesthesia effects. Applying warm blankets helps raise body temperature, reducing shivering. Oxygen is crucial post-surgery. Taking rectal temperature or adjusting room temperature is not the priority. Paging the doctor should only be done if the patient's condition worsens.
