The nurse instructs a patient who has osteosarcoma of the tibia about a scheduled above-the-knee amputation. Which statement by a patient indicates additional patient teaching is needed?

Correct Answer: C

Rationale: Rationale for Correct Answer (C): The statement "I did not have this bone cancer until my leg broke a week ago" indicates a lack of understanding about osteosarcoma, a type of bone cancer. Osteosarcoma does not develop as a result of a broken bone; rather, it is a primary bone cancer that arises from bone cells. This statement suggests a misunderstanding of the nature of the disease, indicating a need for further patient education. Summary of Incorrect Choices: A: Choice A is correct as physical therapy is typically recommended after amputation to aid in rehabilitation and improve mobility. B: Choice B is not indicative of a need for additional teaching as chemotherapy is often part of the treatment plan for osteosarcoma. D: Choice D is also not a sign for additional teaching as PCA is commonly used for postoperative pain management after amputation surgery.

Correct Answer: B

Rationale: The correct answer is B: Alopecia. This does not apply to an older adult who worked in landscaping. Alopecia is not typically associated with working in landscaping, while choices A, C, and D are more likely to be relevant due to sun exposure and skin irritation. Vitiligo may develop due to sun exposure, intertrigo can result from skin friction and moisture, and erythema can be caused by excessive sun exposure. Alopecia, which is hair loss, is not directly related to the work environment in landscaping.

Correct Answer: A

Rationale: The correct answer is A: Acne vulgaris. Acne vulgaris is a skin disorder caused by bacterial overgrowth in hair follicles. Systemic antibiotics can target the bacteria and reduce inflammation, leading to improvement. Urticaria, atopic dermatitis, and verrucae are not primarily caused by bacterial infections, so systemic antibiotics would not be the first-line treatment for these conditions. Urticaria is usually treated with antihistamines, atopic dermatitis with topical corticosteroids, and verrucae with various topical treatments or procedures.

Correct Answer: B

Rationale: The correct answer is B: Hemodynamic instability. In severe electrical burns, the most immediate threat is hemodynamic instability due to fluid shifts and potential cardiac arrhythmias. This can lead to shock and organ failure. Addressing hemodynamic stability is crucial to prevent further complications. Choice A: Infection is a concern in burn injuries but is not the most immediate threat to survival in this case. Choice C: Acute pain is important to manage but does not pose an immediate threat to survival. Choice D: Decreased protein synthesis and impaired healing are long-term consequences of burns and not the most immediate threat to survival in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Varicella. The presentation of macules on the trunk, extremities, and mucous membranes along with extreme pruritus and mild fever is classic for varicella (chickenpox). Varicella is a common childhood viral infection caused by the varicella-zoster virus. The initial macules progress to vesicles and then crust over. The child's age, distribution of skin lesions, and symptoms all point towards varicella. Lichen planus (B) typically presents as purple, itchy, flat-topped papules. Rosacea (C) is a chronic skin condition characterized by facial redness and acne-like bumps. Impetigo (D) is a bacterial skin infection that typically presents with honey-colored crusts and blisters.
