Correct Answer: C

Rationale: Positive fibrin split products indicate disseminated intravascular coagulation (DIC), a condition characterized by the widespread formation of blood clots throughout the body. In DIC, clotting factors are consumed, leading to increased fibrin split products. A shortened prothrombin time (Choice A) is not typically seen in DIC as it indicates faster blood clotting, which is not consistent with the pathophysiology of DIC. An increased fibrinogen level (Choice B) is also not a characteristic finding in DIC, as fibrinogen levels may be decreased due to consumption in the formation of clots. Increased platelets (Choice D) are not typically observed in DIC; instead, thrombocytopenia (decreased platelet count) is more common due to their consumption in clot formation.

Correct Answer: A

Rationale: The correct answer is giving a pacifier to the newborn. Sucking is a natural reflex and a source of comfort for newborns, especially postoperatively. A pacifier can help meet their developmental needs by providing soothing comfort. Choices B, C, and D do not directly address the major developmental need related to the newborn's comfort and reflexes postoperatively. Putting a mobile over the crib, providing a cuddly toy, or warming formula, although potentially beneficial in other contexts, do not specifically target the developmental need of sucking for comfort. Offering a pacifier is a safe and effective way to address this developmental need in newborns.

Correct Answer: A

Rationale: Infection is the leading cause of shock in infants and children due to their heightened vulnerability to sepsis. Infants and children possess developing immune systems, rendering them more susceptible to infections that can progress to septic shock. While cardiac failure is a severe condition, it is not as commonly the primary cause of shock in this age group. Accidental poisoning, though a potential shock inducer, is less prevalent in infants and children compared to infections. Severe allergic reactions, though significant, are not as frequent as infections in precipitating shock in infants and children.

Correct Answer: B

Rationale: Systolic blood pressure is the least reliable parameter when assessing the perfusion status of a 2-year-old child with possible shock. In pediatric patients, especially young children, blood pressure may not decrease until significant shock has already occurred, making it a late indicator of inadequate perfusion. Depending solely on systolic blood pressure to evaluate perfusion status in this age group can lead to a delay in appropriate interventions. Distal capillary refill time, skin color, and temperature changes, and the presence of peripheral pulses are more sensitive and early indicators of perfusion status in pediatric patients. Monitoring distal capillary refill provides information on peripheral perfusion, while changes in skin color and temperature can signal circulatory compromise. Evaluating the presence or absence of peripheral pulses offers insights into vascular perfusion. These parameters offer more reliable and prompt feedback on a child's perfusion status compared to systolic blood pressure.

Correct Answer: A

Rationale: Preventing shivering is crucial in this scenario as it can increase body temperature and counteract the effects of antipyretic measures aimed at reducing the fever. Shivering generates heat through muscle activity, which can elevate the body temperature. Restricting oral fluids (choice B) is inappropriate as maintaining hydration is vital, especially in cases of fever and vomiting. Measuring output hourly (choice C) and taking vital signs hourly (choice D) are important nursing actions but not the most critical in this case where preventing shivering takes precedence.
