Correct Answer: A

Rationale: Padding on a restraint helps distribute pressure to prevent bony prominences from bearing excessive pressure when a client pulls against the restraints. This is crucial to avoid tissue damage caused by ischemia. The correct answer focuses on the physiological benefit of padding in reducing pressure on vulnerable areas to prevent harm. Choice B is incorrect as the primary purpose of padding is not emotional comfort but preventing physical harm. Choice C is incorrect as while padding can indirectly help prevent infection and wounds by reducing pressure, its primary function is pressure distribution. Choice D is incorrect as the main purpose of padding is not to keep the restraints in place but to protect the client's skin and tissues from pressure-related injuries.

Correct Answer: B

Rationale: The correct statement regarding preparation for a lipoprotein fractionation test is that the client cannot eat for 12 hours before the test. It is important to note that the client can drink an unrestricted amount of water. Limiting fluid intake is not necessary for this test. There is no need for the client to ingest a lipid solution as part of the preparation. Therefore, the other choices are incorrect.

Correct Answer: B

Rationale: The correct answer is B. Restraints are used as an emergency intervention when all other options to protect a client from imminent danger have been exhausted. Restraints should only be used as a last resort to ensure the safety of the client and others. Choices A, C, and D are incorrect because restraints are not used to maintain control, reinforce behavior, or are exclusively taken under direct physician supervision. It is crucial to remember that restraint use should always be based on careful assessment, documentation, and adherence to legal and ethical guidelines.

Correct Answer: B

Rationale: Attaching a restraint to a movable part of the bed can lead to client injury if that part of the bed is moved before releasing restraints. This could result in the client getting caught or trapped, possibly causing harm. Choices C and D are incorrect because attaching restraints to movable parts of the bed is not intended to help the client stay in bed or improve posture; rather, it poses a risk of injury. Choice A is incorrect as it does not address the potential harm associated with using restraints on movable parts of the bed.

Correct Answer: B

Rationale: In the scenario described, where multiple passengers on an airliner experience sudden weakness and breathing difficulty simultaneously, the most likely cause is chemical exposure. This is because a sudden onset of similar symptoms in a group of individuals suggests a common environmental factor affecting them. Options A, C, and D are less likely as they do not explain a sudden onset of symptoms in multiple individuals simultaneously. Asian flu (Option A) is a viral infection and would not typically result in sudden symptoms in multiple individuals at the same time. Bacterial pneumonia (Option C) is a localized infection and not a probable cause for a sudden onset of symptoms in a group. An allergic reaction (Option D) would usually occur in individuals with specific allergies rather than affecting a group of passengers at the same time.
