Correct Answer: A

Rationale: Corrected Rationale: Chronic lead poisoning can lead to severe and irreversible damage to the central nervous system, including cognitive and developmental delays. Central nervous system damage is the most serious effect of chronic lead poisoning because it can have long-lasting consequences on a child's cognitive function and overall development. Moderate anemia (Choice B), renal tubule damage (Choice C), and growth impairment (Choice D) can also occur due to lead poisoning, but they are not as severe or potentially irreversible as the damage to the central nervous system.

Correct Answer: B

Rationale: After a water deprivation test in a client suspected of having diabetes insipidus, the nurse would expect the urine specific gravity to remain unchanged. This occurs because in diabetes insipidus, the kidneys are unable to concentrate urine, leading to a low urine specific gravity even after water deprivation. Choices A, C, and D are incorrect. Increased edema and weight gain are not typical findings in diabetes insipidus. Rapid protein excretion is not directly related to the condition, and decreased blood potassium is not a common outcome of a water deprivation test for diabetes insipidus.

Correct Answer: C

Rationale: The correct answer is C because the milk code emphasizes that companies should always acknowledge the superiority of breastmilk over formula. Choice A is incorrect because the focus is not on the public receiving information, but rather on companies recognizing breastmilk's superiority. Choice B is incorrect as it addresses health workers' actions, not the companies' behavior. Choice D is incorrect as the milk code is primarily concerned with regulating companies' practices, not health workers' acceptance of incentives.

Correct Answer: C

Rationale: The correct answer is C, 'All of the above.' Both village health workers and barangay health workers are trained community health workers or health auxiliary volunteers. Choice A, 'Village health workers,' is correct as they are trained community health workers. Choice B, 'Barangay health workers,' is also correct as they also refer to trained community health workers. Therefore, since both options A and B are accurate, the correct answer is C, 'All of the above.' Choice D, 'None of the above,' is incorrect as both village health workers and barangay health workers fit the description provided in the question.

Correct Answer: B

Rationale: The correct answer is B: Hyperglycemia. In peritoneal dialysis, hyperglycemia can occur due to the glucose content of the dialysate solution. This high glucose concentration can lead to increased blood sugar levels in the client. Option A, Hypertension, is a common complication in chronic renal failure but is not directly related to peritoneal dialysis. Option C, Hypokalemia, is more commonly associated with loop diuretics or inadequate potassium intake. Option D, Hypernatremia, is more often seen in conditions of excessive sodium intake or water loss, rather than in peritoneal dialysis.
