Which of the following is an indication for tracheostomy?

Correct Answer: D

Rationale: The correct answer is D: Acute respiratory failure. Tracheostomy is indicated in cases of severe respiratory compromise when the upper airway is obstructed or when long-term mechanical ventilation is needed. It ensures a patent airway and facilitates weaning from a ventilator. Choices A, B, and C are incorrect as drainage of pleural effusion, hemorrhage, and infections do not typically require a tracheostomy for management.

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.

Correct Answer: A

Rationale: Step 1: Understanding the health needs of the population is crucial as it helps in identifying the priority areas for intervention. Step 2: By focusing on health needs, the program can address the most pressing issues, leading to more effective outcomes. Step 3: Considering available resources or demographics without knowing the health needs may result in ineffective or irrelevant interventions. Step 4: The current health status is important but may not provide a comprehensive view of the underlying needs that require addressing.
