Which finding suggests fluid volume deficit in an infant presenting with vomiting and diarrhea for 2 days?

Correct Answer: B

Rationale: A sunken fontanel is a classic sign of dehydration in infants, indicating a fluid volume deficit. In dehydration, the fontanel sinks due to decreased fluid volume in the body. Increased blood pressure (Choice A) is not typically associated with dehydration in infants. Decreased pulse rate (Choice C) is not a common finding in fluid volume deficit, as the body tries to increase the heart rate to compensate for decreased volume. Low urine specific gravity (Choice D) may be seen in dehydration, but it is not as specific or as easily observable as a sunken fontanel.

Correct Answer: C

Rationale: Proper perineal hygiene, including cleansing with water after voiding, is crucial in preventing UTIs in young girls. Avoiding public toilets and limiting baths are less effective than proper hygiene practices.

Correct Answer: C

Rationale: The correct answer is C: Failure to pass meconium and abdominal distension. Hirschsprung's disease is commonly diagnosed in newborns due to the failure to pass meconium within the first 24-48 hours after birth and abdominal distension, indicating a bowel obstruction. Choices A, B, and D are incorrect because they do not correspond to the typical symptoms of Hirschsprung's disease. Acute diarrhea and dehydration, current jelly-like stools and pain, and projectile vomiting with altered electrolytes are not characteristic of this condition.

Correct Answer: C

Rationale: The correct answer is C, the Supplemental Food Program for Women, Infants, and Children (WIC). WIC provides nutritional assistance to low-income pregnant women, breastfeeding women, and children under 5. The Division of Maternal and Child Health (Choice A) focuses on promoting the health of mothers and children but does not provide direct nutritional assistance. Medicaid (Choice B) is a health insurance program for low-income individuals but does not specifically address nutritional needs. The State Children's Health Insurance Program (Choice D) provides health insurance for children in low-income families but does not offer nutritional support like WIC does.

Correct Answer: A

Rationale: Hemolytic uremic syndrome (HUS) typically presents with hematuria, anorexia, hypertension, and purpura due to the hemolytic anemia, thrombocytopenia, and renal failure that characterize this condition.

Correct Answer: A

Rationale: Cystitis is the medical term for inflammation of the bladder. Urethritis refers to inflammation of the urethra, urosepsis to a systemic infection stemming from the urinary tract, and bacteriuria to the presence of bacteria in the urine.

Correct Answer: A

Rationale: It is important for the nurse to provide the parents with accurate information so they can confidently explain the situation to others, helping to reduce stress and misinformation. Avoiding family and friends or minimizing the problem is not helpful.

Correct Answer: C

Rationale: Vegetables, particularly pureed ones, are often recommended as a first solid food for infants because they are easy to digest and less likely to cause allergies. Fruits can be introduced later due to their natural sweetness, while eggs and meat are typically introduced after fruits and vegetables as they may pose a higher risk of allergies.

Correct Answer: B

Rationale: The most effective method to prevent infection in newborns is by practicing proper hand hygiene by staff and family. This is crucial as it helps reduce the transmission of infectious agents, protecting vulnerable newborns. Using disposable items may help, but proper hand hygiene is more effective. Administering prophylactic antibiotics without a specific indication can lead to antibiotic resistance and is not recommended. Isolating the newborn from others is not practical and may not be necessary if proper hand hygiene is maintained.
