Correct Answer: B

Rationale: Using pillows to keep the client's extremities in a functional position is crucial in preventing joint contractures. This intervention helps maintain proper alignment of the joints and reduces the risk of contractures by preventing prolonged positioning that can lead to muscle shortening. Encouraging the client to perform active range-of-motion exercises (Choice A) is beneficial for maintaining mobility but may not be the most important intervention to prevent joint contractures. Placing the client in a prone position for 30 minutes each day (Choice C) can be helpful for preventing pressure ulcers but is not directly related to preventing joint contractures. Performing passive range-of-motion exercises on the affected side (Choice D) can aid in maintaining joint flexibility but may not be as crucial as using pillows to prevent joint contractures.

Correct Answer: D

Rationale: Choice D is the correct answer because having the 4-year-old help feed the four-month-old a bottle in the kitchen while the mother makes supper shows supervision of the infant by the older child in a safe environment. This choice indicates that the mother understands safety precautions by involving the older child in a caregiving task under her supervision. Choices A, B, and C are incorrect because they involve unsafe practices such as placing the infant on the floor unsupervised, positioning the infant car seat in the front seat, and not providing direct supervision of the children during naptimes.

Correct Answer: D

Rationale: The correct answer is D because maturational loss is related to developmental changes, such as children leaving for college. This type of loss is tied to the normal life transitions of individuals and can lead to feelings of grief and adjustment. Choices A, B, and C represent different types of losses. Choice A involves a traumatic loss of a child due to illness, choice B involves a financial loss impacting the head of household's job, and choice C involves a material loss due to a fire incident. While these losses are significant, they do not specifically relate to maturational loss, which is associated with expected life stage transitions.

Correct Answer: A

Rationale: When a nurse assesses body alignment, they are observing the relationship of one body part to another in various positions. This involves evaluating the positioning of joints, tendons, ligaments, and muscles while a person is standing, sitting, or lying down. Choice B is incorrect because it refers more to the coordination between the musculoskeletal and nervous systems, which is not specifically related to body alignment assessment. Choice C is incorrect as it describes the force opposing movement rather than body alignment. Choice D is incorrect as it defines the ability to move freely, which is not directly related to monitoring body alignment.

Correct Answer: A

Rationale: The correct answer is A: Chamomile. Chamomile tea is commonly used for stress relief. Choice B, Ginseng, is not typically used in teas for stress relief but for energy and immune system support. Choice C, Ginger, is more commonly used for digestive health and nausea. Choice D, Echinacea, is often used to boost the immune system. Therefore, in the context of stress relief, Chamomile is the most appropriate ingredient.
