Which of the following are major veins commonly used in parenteral cannulation?

Correct Answer: D

Rationale: I'm sorry, but the correct answer provided (D: Aorta) is actually incorrect in this context. The major veins commonly used in parenteral cannulation are A: Basilic vein, B: Femoral vein, and C: Subclavian vein. The aorta is a major artery, not a vein, and is not typically used for parenteral cannulation due to its high pressure and risk of complications. It's important to understand the differences between veins and arteries when considering cannulation sites.

Correct Answer: A

Rationale: Rationale: 1. Bone marrow puncture is not indicated for analgesia but for diagnostic purposes. 2. Antibiotics may be indicated to prevent infection during the procedure. 3. Anaesthesia may be used to minimize pain and discomfort. 4. Inflammation is a condition that may necessitate bone marrow puncture for diagnosis. Therefore, choice A is the correct answer as it does not align with the therapeutic indications of bone marrow puncture.

Correct Answer: D

Rationale: The correct answer is D because in a complete spinal injury, both motor and sensory functions are lost below the level of the injury. This occurs due to the disruption of communication between the brain and the rest of the body. Choice A is incorrect as it implies that only some functions are lost, which is not the case in a complete injury. Choice B is incorrect because sensory functions are also affected in a complete spinal injury. Choice C is incorrect as it suggests that only sensory functions are lost, which is not true for a complete spinal injury.

Correct Answer: D

Rationale: Certainly! The correct answer is D: Ataxia. Ataxia refers to the failure of muscle coordination, resulting in unsteady movements and a staggering walk. The cerebellum controls balance and coordination, so disorders in this area can lead to ataxia. A: Anoxia refers to a lack of oxygen supply to tissues, not related to muscle coordination. B: Dyslexia is a learning disorder involving difficulty with reading, unrelated to muscle coordination. C: Paraplegia is paralysis of the lower half of the body, not specifically related to muscle coordination issues seen in ataxia.

Correct Answer: A

Rationale: The correct answer is A because risk is defined as the probability that an individual will develop a specific condition. This involves assessing the likelihood of an event occurring. Choice B focuses on the impact of a health condition, which is not the same as risk assessment. Choice C refers to the potential harm, but risk includes both the probability and potential consequences. Choice D is about exposure to health hazards, which is related to risk but doesn't fully encompass the concept. Therefore, option A best captures the essence of risk assessment.
