Correct Answer: C

Rationale: Using a mechanical lift is an appropriate ergonomic technique as it reduces the risk of injury to both the nurse and the client by promoting safe client handling practices. Choice A is incorrect as standing with feet shoulder-width apart provides better balance and stability during lifting. Choice B is incorrect as raising the client's knees is not directly related to ergonomic principles. Choice D is incorrect as placing a gait belt around the client's waist is a safety measure but does not specifically demonstrate an understanding of ergonomic principles.

Correct Answer: C

Rationale: The correct action for the nurse to take is to ensure that the newborn wears a diaper. This is important to prevent irritation during phototherapy, as exposure to light can increase the risk of skin breakdown. Feeding the infant glucose water is unnecessary and not indicated for jaundice treatment. Keeping the infant's head uncovered allows the light to reach the skin effectively. Applying lotion to the newborn every 4 hours can interfere with the effectiveness of phototherapy and is not recommended.

Correct Answer: B

Rationale: Cheddar cheese is a rich source of calcium and should be recommended to clients with osteoporosis. While broccoli and almonds also contain calcium, cheddar cheese provides a higher amount per serving. Fortified orange juice may contain added calcium, but it is not as concentrated a source as cheddar cheese. Therefore, the best choice for a client with osteoporosis seeking a high calcium food is cheddar cheese.

Correct Answer: C

Rationale: The correct action for the nurse when caring for a client with thrombocytopenia is to provide the client with a stool softener. Thrombocytopenia is characterized by a low platelet count, leading to increased bleeding tendencies. Providing a stool softener helps prevent constipation, reducing the likelihood of straining during bowel movements and subsequent bleeding. Encouraging the client to floss daily (choice A) is unrelated to managing thrombocytopenia. Removing fresh flowers from the client's room (choice B) pertains more to infection control than addressing thrombocytopenia. Avoiding serving raw vegetables (choice D) is not directly associated with managing thrombocytopenia symptoms.

Correct Answer: C

Rationale: The correct answer is C. Clients taking prednisone should avoid crowded places to reduce the risk of infection due to immunosuppression. Choice A is incorrect because prednisone should be taken with food to reduce stomach upset. Choice B is incorrect as prednisone is usually prescribed for a specific duration and not for life. Choice D is incorrect because prednisone should be taken as prescribed by the healthcare provider, which may not always align with symptom resolution.
