TachypneaAnswer D.RATIONALE: The body compensates for metabolic acidosis via the respiratory system, whichtries to eliminate the buffered acids by increasing alveolar ventilation through deep, rapidrespirations, altered white blood cell or platelet counts are not specific signs of metabolicimbalance.3. After the nurse provides dietary restrictions to the parents of a child with celiac disease,which statement by the parents indicates effective teaching?a. ³Well follow these instructions until our child¶s symptoms disappear.´ b. ³Our child must maintain these dietary restrictions until adulthood.´c. ³Our child must maintain these dietary restrictions lifelong.´d. ³We¶ll follow these instructions until our child has completely grown and developed.´Answer C.RATIONALE: A patient with celiac disease must maintain dietary restrictions lifelong to avoidrecurrence of clinical manifestations of the disease.

The nurseshould monitor this client¶s fluid intake because fluid overload may cause:a. Cerebral edema b. Dehydrationc. Heart failured. Hypovolemic shock Answer A.RATIONALE: Because of the inflammation of the meninges, the client is vulnerable todeveloping cerebral edema and increase intracranial pressure. Fluid overload won¶t causedehydration. It would be unusual for an adolescent to develop heart failure unless theoverhydration is extreme. Hypovolemic shock would occur with an extreme loss of fluid of  blood
