Correct Answer: B

Rationale: The correct answer is Osteoarthritis. Osteoarthritis is characterized by hard, nontender nodules of 2 to 3 mm or larger. These osteophytes (bony overgrowths) of the distal interphalangeal joints are called Heberden nodes. In this disorder, when these nodes occur on the proximal interphalangeal joints, they are called Bouchard nodes. Heberden nodes are not associated with scoliosis, rotator cuff lesions, or carpal tunnel syndrome. Therefore, choices A, C, and D are incorrect.

Correct Answer: B

Rationale: Erik Erikson is credited with the psychosocial development theory and eight stages. The nurse should consider these stages when caring for pediatric clients to evaluate their development. Jean Piaget is known for cognitive development, Sigmund Freud for psychosexual development, and Robert Peck for aging theory. Therefore, the correct answer is Erik Erikson.

Correct Answer: B

Rationale: The correct answer is '6 months.' At around this age, children typically start to develop 'stranger anxiety' as they become more aware of unfamiliar faces and may start showing signs of distress or anxiety around strangers. At 3 months, infants are still very young and unlikely to display stranger anxiety. While by 9 or 12 months, children have usually already developed some level of stranger anxiety, it typically starts around 6 months, making it the most appropriate answer in this context.

Correct Answer: C

Rationale: This client is at risk for altered body image due to chemotherapy-induced hair loss. A wig can assist in coping with this change. It is advisable for the client to shop for a wig before hair loss occurs to better match color and style. Waiting until all hair falls out may lead to stress and limited options in finding a suitable wig. Choices A, B, and D are accurate. Understanding the timing of susceptibility to infection, maintaining oral health before chemotherapy, and staying hydrated are important aspects of care during chemotherapy. Therefore, the statement 'I should wait until all my hair falls out to purchase a wig' requires additional follow-up and education.

Correct Answer: B

Rationale: The correct answer is B. Amiodarone can cause increased photosensitivity, making it essential for the client to wear sunblock when exposed to sunlight. Choice A is incorrect because numbing or tingling in the feet is not a common side effect of Amiodarone. Choice C is unrelated as the drug does not typically require supplemental vitamin B12. Choice D is also incorrect as there is no need to avoid leafy vegetables specifically due to Amiodarone.
