Correct Answer: A

Rationale: When pulling a client, you work with the gravitational force instead of opposing it, which reduces the workload on your muscles. Choosing to pull a client minimizes the effort required compared to pushing. Choice B is incorrect because the force of gravity remains constant regardless of pushing or pulling. Choice C is irrelevant as stability is not directly related to the advantage of pulling over pushing. Choice D is inaccurate because pulling can still strain muscles if not executed correctly, but it generally reduces the overall workload in comparison to pushing.

Correct Answer: A

Rationale: When transferring a client from a wheelchair to the bed, the correct procedure is to pull the client toward you, which reduces workload force. By pivoting the client on the unaffected limb, strength is maintained to support the affected limb while moving towards the bed. Choice A is correct because it ensures a safe and effective transfer technique. Choices B, C, and D are incorrect as they involve incorrect positioning and movements that could potentially harm the client or increase the risk of injury. Pulling the client towards you puts less strain on your back and reduces the risk of injury. Pivoting on the unaffected limb ensures better support for the client's affected limb during the transfer process.

Correct Answer: D

Rationale: Hazards of improper splinting can lead to the aggravation of a bone or joint injury, reduced distal circulation, and delay in transporting a client with a life-threatening injury. Choosing 'All of the above' (Option D) is the correct answer as it encompasses all the hazards mentioned. Option A is incorrect because it only addresses one aspect of the hazards. Option B is incorrect as it does not cover all the hazards associated with improper splinting. Option C is incorrect as it focuses on only one hazard and does not account for the others.

Correct Answer: A

Rationale: The hypothalamus is responsible for regulating sleep patterns among other functions. Injury to the hypothalamus can disrupt the sleep-wake cycle, leading to excessive sleepiness or changes in sleep patterns. Choices B, C, and D are incorrect as they do not primarily control sleep regulation. The thalamus is involved in relaying sensory information, the cortex is responsible for higher brain functions, and the medulla controls vital functions such as heartbeat and breathing.

Correct Answer: A

Rationale: The transplacental transfer of maternal antibodies supplements the infant's weak response to infection until approximately 3 to 4 months of age. While the infant starts producing immunoglobulin (Ig) soon after birth, it only reaches about 60% of the adult IgG level, 75% of the adult IgM level, and 20% of the adult IgA level by 1 year of age. Breast milk provides additional IgA protection. Although the immune system matures during infancy, full protection against infections is not achieved until early childhood, putting the infant at risk for infections. Choice B is incorrect because maternal antibody protection typically lasts around 3 to 4 months, not until the infant is 12 months old. Choice C is incorrect as infants are not shielded from all infections due to their immature immune system. Choice D is incorrect because while breastfeeding offers extra protection, it does not guarantee complete immunity against infections.
