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: D

Rationale: The correct answer is D because some antianxiety medications are considered safe during breastfeeding. The nurse should reassure the client and encourage her to discuss options with her healthcare provider to manage anxiety safely while continuing to breastfeed. Choice A is incorrect because it focuses on the transmission of drugs rather than providing guidance on safe medication use. Choice B, while promoting stress-relieving techniques, does not address the potential need for medication. Choice C is incorrect as it minimizes the woman's reported anxiety, which may require professional intervention.

Correct Answer: D

Rationale: The correct answer is D: "Red streaks tracking the vein." Red streaks indicate phlebitis, an inflammation of the vein that can lead to serious complications like infection or thrombophlebitis. Immediate intervention is required to prevent further damage. Choice A, cool skin at the IV insertion site, could indicate decreased circulation but is not as urgent as addressing phlebitis. Choice B, presence of fluid leaking around the IV catheter, may indicate infiltration or dislodgement of the catheter, requiring intervention but not as urgently as phlebitis. Choice C, swelling above the IV site, may suggest localized inflammation but doesn't pose an immediate threat like phlebitis does.

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.

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.
