A nurse is preparing to administer vaccines to a 1-year-old child. Which of the following vaccines should the nurse give? (Select two)

Choice A: This statement indicates an understanding of the teaching, as washing all recently used clothing, bedding, and towels in hot water can help eliminate lice and nits (eggs). Lice and nits can survive on fabrics for up to two days and can spread from one person to another through direct or indirect contact. Washing items in hot water can kill lice and nits by exposing them to high temperatures.

Choice B: This statement indicates a lack of understanding of the teaching, as nits will not always be present after treatment. Nits are tiny white or yellow oval-shaped eggs that are attached to the hair shaft near the scalp. Nits can hatch into nymphs (young lice) within seven to ten days and mature into adult lice within nine to twelve days. Nits can be removed by using a fine-toothed comb or by applying products that loosen their grip on the hair.

Choice C: This statement indicates a lack of understanding of the teaching, as treating all family members may not be necessary or effective. Treating all family members can expose them to unnecessary chemicals or medications that may have side effects or cause resistance. Treating all family members may also not prevent reinfestation if there are other sources of exposure such as school or daycare. Only family members who have evidence of lice or nits should be treated.

Choice D: This statement indicates a lack of understanding of the teaching, as throwing out toys that can't be dry cleaned or washed may not be required or practical. Throwing out toys can cause emotional distress or financial burden for the child or the parents. Throwing out toys may also not prevent reinfestation if there are other sources of exposure such as clothing or bedding. Toys that can't be dry cleaned or washed can be sealed in plastic bags for two weeks to suffocate the lice and nits.

Choice A: Distended neck veins are not a clinical manifestation of pyloric stenosis, which is a condition that causes the narrowing of the pylorus, which is the opening between the stomach and the small intestine. Distended neck veins are a sign of increased venous pressure, which can occur in conditions that affect the right side of the heart or cause fluid overload.

Choice B: Rigid abdomen is not a clinical manifestation of pyloric stenosis, but rather a sign of peritonitis, which is inflammation of the peritoneum, which is the membrane that lines the abdominal cavity. Peritonitis can be caused by infection, perforation, or trauma to any abdominal organ. A rigid abdomen indicates severe pain and inflammation in the abdominal cavity.

Choice C: Projectile vomiting is a clinical manifestation of pyloric stenosis, as it indicates forceful expulsion of stomach contents due to obstruction at the pylorus. Projectile vomiting can occur shortly after feeding and may contain undigested milk or formula. Projectile vomiting can cause dehydration, electrolyte imbalance, or weight loss.

Choice D: Red currant jelly stools are not a clinical manifestation of pyloric stenosis, but rather a sign of intussusception, which is a condition that causes telescoping of one segment of bowel into another. Intussusception can cause obstruction and ischemia of the bowel and lead to bleeding and necrosis. Red currant jelly stools indicate blood and mucus in the stool.
