To decrease the likelihood of bradyarrhythmias in children during endotracheal intubation, succinylcholine(Anectine) is used with which of the following agents?

Correct Answer: C

Rationale: Succinylcholine administration can lead to bradycardia or bradyarrhythmias in children due to its depolarizing neuromuscular blockade effects. To counteract this detrimental effect and decrease the likelihood of bradyarrhythmias, atropine sulfate is commonly used in conjunction with succinylcholine. Atropine, an anticholinergic agent, works by blocking the action of acetylcholine on muscarinic receptors, which helps prevent vagal-induced bradycardia. This approach is especially important in pediatric patients to maintain a stable heart rate and hemodynamic status during endotracheal intubation.

Correct Answer: B

Rationale: Elevating the head of the bed at a 10 to 20-degree angle helps to increase intrathoracic pressure. This increase in pressure can aid in promoting cerebrospinal fluid drainage and reducing intracranial pressure. It is important to maintain the correct angle to achieve the desired effect and avoid potential complications. If Tiffany's parents mention this as the reason for elevating the bed, Nurse Charlie should reexplain the purpose to ensure they understand the intended outcome.

Correct Answer: D

Rationale: The epiphyseal plate, also known as the growth plate, is the area of growing tissue near the ends of the long bones in children and adolescents. It is crucial for bone growth and development. When a child injures the epiphyseal plate from a fracture, the damage can disrupt the normal growth process of the bone. This disruption can lead to unequal limb length, angular deformities, or other growth abnormalities. Therefore, the damage resulting from an injury to the epiphyseal plate may lead to bone growth disruption. Choices A, B, and C are not directly associated with epiphyseal plate injuries.

Correct Answer: B

Rationale: When assessing a patient like Will for possible intussusception, the least likely to provide valuable information would be the family history. While family history can help identify potential genetic predispositions or conditions that may contribute to a patient's current health concerns, in this case, the focus is on Will's immediate symptoms and diagnostic indicators related to possible intussusception. Abdominal palpation, pain pattern assessment, and stool inspection are more directly relevant to evaluating Will's current condition and determining the likelihood of intussusception. Family history, while important in a broader health context, would be least likely to provide immediate insights into Will's specific situation with intussusception.

Correct Answer: C

Rationale: Ribavirin (Virazole) is an antiviral medication used to treat severe cases of respiratory syncytial virus (RSV) infection in infants, young children, and immunocompromised individuals. RSV is a common virus that causes respiratory infections in people of all ages, but it can be particularly severe in young children and individuals with weakened immune systems. Ribavirin works by preventing the virus from replicating and spreading further in the body, helping to reduce the severity and duration of RSV infection. It is not used to treat cystic fibrosis, otitis media, or bronchitis.
