Correct Answer: B

Rationale: The correct answer is B: Prepare the client for dialysis. Clients with acute kidney injury and elevated creatinine may require dialysis to support kidney function and remove waste products from the blood. Preparing for dialysis ensures timely intervention in preventing further complications. Administering diuretics (Choice A) may worsen the client's condition by further compromising kidney function. Restricting fluid intake (Choice C) may be necessary in some cases, but it is not the priority over preparing for dialysis. Notifying the healthcare provider (Choice D) is important, but the immediate priority is to prepare for dialysis to address the acute kidney injury and elevated creatinine level.

Correct Answer: B

Rationale: The correct answer is B. Young children, like the 2-year-old playing on aging playground equipment, are at higher risk of lead poisoning due to their hand-to-mouth behavior and exploration of their environment. Aging playground equipment may have lead-based paint that can be ingested by the child. While children living in housing projects are also at risk due to lead-based paint in older buildings, the 2-year-old child playing on potentially lead-contaminated playground equipment is the most susceptible in this scenario. The adolescent working in a paint factory may face occupational hazards related to lead exposure, but the immediate risk from environmental sources is higher for the 2-year-old. Type 1 diabetes in a 10-year-old is not directly linked to an increased susceptibility to lead poisoning.

Correct Answer: A

Rationale: The correct answer is to administer antithyroid medications as prescribed during a thyroid storm. Antithyroid medications help control the overproduction of thyroid hormones, which is crucial in managing symptoms such as increased heart rate and tremors. These symptoms can be life-threatening if not promptly addressed. Administering a beta-blocker (Choice B) may help control the heart rate, but addressing the underlying cause with antithyroid medications is the priority. Monitoring the client's temperature (Choice C) is important but not the priority intervention during a thyroid storm. Lastly, preparing the client for an emergency thyroidectomy (Choice D) is not the initial intervention for managing symptoms of a thyroid storm.

Correct Answer: D

Rationale: In clients with altered renal function being treated at home, weekly weight is the most accurate indicator of fluid balance. Fluid retention or loss can significantly affect weight, making it a reliable measure. Choices A, B, and C are not as accurate indicators of fluid balance as weekly weight. Intake and output differences can vary in accuracy and may not capture all aspects of fluid balance. Changes in mucous membranes and skin turgor can be influenced by factors other than fluid balance, making them less precise indicators.

Correct Answer: C

Rationale: The correct answer is C, 'Diminished breath sounds bilaterally.' This finding should be reported immediately as it could indicate a serious complication such as increased intracranial pressure or respiratory compromise. In a post-craniotomy client, changes in breath sounds may be a sign of developing issues that need prompt intervention. Choices A, B, and D are not as critical in the immediate post-craniotomy period. Pupils equal and reactive to light are expected findings, a sudden increase in urine output may require monitoring but not immediate reporting, and a small increase in blood pressure may not be alarming unless it is significantly high or accompanied by other concerning signs.
