Correct Answer: B

Rationale: The correct answer is 'behavior modification.' The Token Economy is a form of behavior modification that involves providing positive reinforcement in the form of tokens or rewards for desired behaviors. This approach aims to increase the occurrence of positive behaviors by rewarding them. Play therapy (choice A) focuses on using play as a medium for therapeutic communication, not specifically behavior modification. Milieu therapy (choice C) involves shaping the environment to promote desired behaviors but is not the primary focus of the Token Economy. 'Associative' (choice D) is not directly related to the Token Economy or its focus on behavior modification, making it an incorrect choice.

Correct Answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, Heparin sodium, is an anticoagulant and is not routinely used to flush an IV device before and after the administration of blood.

Correct Answer: C

Rationale: The correct answer is 'when needs change.' The nurse should be flexible and adjust the plan as necessary when the needs of the patients change. This ensures that care is provided effectively and efficiently. Choices A, B, and D are incorrect because altering the plan based on time intervals, solely at the end of the shift, or after completing top-priority tasks may not align with the current needs of the patients.

Correct Answer: A

Rationale: The correct answer is A, a cephalohematoma. A cephalohematoma is an area of bleeding outside the cranium but beneath the periosteum, typically not crossing the suture line. Answer B, molding, is the overlapping of the bones of the cranium and does not involve bleeding, making it an incorrect choice. Answer C, a subdural hematoma, involves intracranial bleeding and is typically diagnosed through imaging studies like a CAT scan or x-ray. Answer D, caput succedaneum, is characterized by edema that crosses the suture line, unlike the described swelling in this case.

Correct Answer: B

Rationale: Correct answer: Special hair, skin, and nail care might be required. African-American clients may have specific hair, skin, and nail care needs due to their unique characteristics such as curly hair and melanin-rich skin. It is important for healthcare providers to be knowledgeable about these needs to provide appropriate care. Option A is incorrect as it does not address the specific care aspect related to the clients themselves. Option C is incorrect as assuming all African-American clients follow cultural diets is a stereotype and may not apply to every individual. Option D is incorrect as being future-oriented is not a characteristic that is universally applicable to African-American clients and does not directly impact nursing care considerations.
