RN PEDIATRIC Exam 2 (160 Questions with Complete Solution +Rationale >>What is described as the time interval between early manifestations of a disease and the overt clinical syndrome? A. Incubation... period B. Prodromal period C. Desquamation period D. Period of communicability {{Correct Ans- B. Prodromal period The prodromal period is defined as the symptoms that occur between early manifestations of the disease and overt clinical symptoms. The incubation period is the time from exposure to the appearance of the first symptom. The desquamation period refers to the shedding of skin when applicable for a syndrome or disorder. The period of communicability describes the period when the child is infectious. >>The nurse is concerned with the prevention of communicable disease. Primary prevention results from A. Immunizations B. Early diagnosis C. Strict isolation D. Treatment of disease {{Correct Ans- A. Immunizations Communicable diseases are prevented through immunizations, which constitute primary prevention. Early diagnosis can prevent the spread of communicable disease by initiating treatment and isolation if necessary; this would be considered secondary prevention. Strict isolation would be considered part of the treatment regimen and would constitute tertiary prevention, which is the prevention of complications or sequelae. Treatment of disease would not prevent communicable disease. >>The school nurse is concerned about an outbreak of chickenpox because two children at the school have cancer and are immunodeficient from chemotherapy. The most appropriate recommendation by the school nurse is that A. no precautions necessary. B. Acyclovir (Zovirax) should be taken to minimize the symptoms of chickenpox. C. Varicella-zoster immune globulin (VZIG) to prevent chickenpox. D. temporarily stopping chemotherapy will allow the immune system to recover. {{Correct Ans- C. Varicella-zoster immune globulin (VZIG) to prevent chickenpox. VZIG is an antibody to the virus that causes chickenpox. Administration of VZIG can prevent development of the disease in immunocompromised children secondary to chemotherapy. Chickenpox can be a life-threatening event for a child who is immunocompromised and must be addressed. Acyclovir is effective in reducing the number of lesions from chickenpox, but in immunodeficient children the disease itself should be prevented. The administration of VZIG does not place the child at any greater risk; therefore, there is no need to stop chemotherapy. >>The most appropriate comfort intervention for a child with itching related to chickenpox is A. encourage frequent warm baths. B. give aspirin or acetaminophen (Tylenol). C. apply thick coat of pramoxine (Caladryl) lotion over open lesions. D. give an antipruritic medication such as diphenhydramine (Benadryl). E. apply thick coat of pramoxine (Caladryl) lotion over open lesions. {{Correct Ans- D. give an antipruritic medication such as diphenhydramine (Benadryl). Antipruritic medicines such as diphenhydramine are useful for severe itching, which interferes with sleep and may contribute to secondary infection. Cool baths, not warm ones, are recommended for relief of itching secondary to chickenpox. Neither drug provides antipruritic effects, nor should aspirin ever be given to children with chickenpox, because there is an increased risk of developing Reye syndrome. Caladryl lotion, which contains diphenhydramine, should be applied sparingly, not in thick coats, over open lesions to minimize absorption. >>What is the causative agent for erythema infectiosum (fifth disease)?
