Rationale: The nurse should reassure the mother that the child's behavior is normal for their age and situation.

Correct Answer: C

Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.

Correct Answer: B

Rationale: Granulation tissue is a hallmark of healing in wounds. It appears as translucent and red, indicating angiogenesis and the formation of new blood vessels in the wound bed. This tissue is vital for wound healing as it provides a scaffold for cell migration and promotes re-epithelialization. Choices A, C, and D do not describe granulation tissue accurately. Stringy, white tissue may suggest fibrin, soft, yellow tissue could indicate slough, and thick, black tissue may imply necrotic tissue, all of which are not synonymous with granulation tissue and do not signify the healing process.

Correct Answer: A

Rationale: The correct answer is A. Changing the colostomy bag every day is not necessary; it should be changed as needed, usually every 3-7 days. This statement indicates a need for additional teaching as frequent changes can irritate the skin and are not typically required. Choices B, C, and D are all correct statements regarding colostomy care. Avoiding gas-producing foods, emptying the bag when it is one-third to one-half full, and taking care of the skin around the stoma are all essential aspects of colostomy care to prevent complications and maintain skin integrity.

Correct Answer: A

Rationale: When assessing a child with asthma, it is crucial to gather information about potential triggers in their environment. Household pets, such as cats or dogs, are common triggers for asthma attacks due to pet dander and saliva. This information is essential to identify if exposure to pets at home could be exacerbating the child's asthma symptoms. Choices B, C, and D are less relevant in the context of asthma triggers. New furniture, lead-based paint, and plants like cactus are not typically primary triggers for asthma attacks compared to common allergens like pet dander.
