Correct Answer: B

Rationale: The correct answer is Standard Precautions. Standard precautions are taken in all situations for all clients and involve all body secretions except sweat. They are designed to reduce the rate of transmission of microbes from one host to another or one source to another. Respiratory Isolation (Choice A) is used for diseases transmitted by airborne particles, not secretions and blood. Contact Isolation (Choice C) is for clients known or suspected to be infected with microorganisms that can be transmitted by direct or indirect contact. Droplet Isolation (Choice D) is used for diseases transmitted by large respiratory droplets expelled during coughing, sneezing, talking, or procedures.

Correct Answer: B

Rationale: A client with hypercholesterolemia needs to decrease intake of foods that are high in cholesterol. Red meats like hamburgers are high in cholesterol, so their consumption should be reduced. Broiled catfish, wheat bread, and fresh apples are not high in cholesterol and do not need to be decreased in the client's diet. Therefore, the correct answer is hamburgers, as they are more likely to contribute to elevated cholesterol levels compared to the other options provided.

Correct Answer: B

Rationale: The correct answer is 'Toddlers.' Toddlers are at the highest risk of unintentional poisoning due to their natural curiosity, explorative behavior, and lack of awareness of potential dangers. Infants are typically closely monitored, teens are more aware of risks, and adults generally have better judgment and understanding of hazardous substances, making them less susceptible to unintentional poisoning. Therefore, toddlers, being inquisitive and unaware of risks, are the most vulnerable group in terms of unintentional poisoning incidents.

Correct Answer: C

Rationale: To provide total oral care to a client, the nurse should first assemble all necessary equipment. Placing the client in a side-lying position helps fluids to easily flow out or pool in the side of the mouth for suctioning, thus preventing aspiration. Additionally, placing a towel under the client's chin and a curved basin against the chin helps to maintain cleanliness during the procedure. Choice A is incorrect because the client should be placed in a side-lying position, not a semi-Fowler's position which is used for respiratory issues. Choice B is incorrect as it does not emphasize the importance of proper positioning for effective oral care. Choice D is incorrect as it oversimplifies the procedure by focusing only on cleaning the mouth without considering the importance of positioning and preparation.

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.
