Correct Answer: C

Rationale: The indicators listed indicate measures that Nurse Cirila can take to maintain a safe environment for her pediatric patients. However, assessing the competencies of staff before delegating a task is more related to ensuring effective delegation and appropriate task assignment rather than directly ensuring a safe environment for patients. While it is important to delegate tasks to qualified staff, this specific action does not directly contribute to maintaining a safe environment in the same manner as the other indicators listed (proper waste disposal, infection control, emergency protocols).

Correct Answer: A

Rationale: Betamethasone (Celestone) is a corticosteroid medication that is commonly used to promote fetal lung maturity in pregnant women at risk of preterm delivery. Administering betamethasone to the mother helps accelerate the production of surfactant in the fetal lungs, which is essential for proper lung function and development. This medication is typically given to pregnant women between 24 and 34 weeks of gestation to reduce the risk of respiratory distress syndrome in preterm infants. It does not prevent premature closure of the ductus arteriosus, delay delivery, or stop premature uterine contractions.

Correct Answer: A

Rationale: Zenker's diverticulum is a condition in which there is a pouch or sac that forms at the posterior pharyngeal wall above the upper esophageal sphincter. It can present with symptoms such as sensation of a foreign body stuck in the throat, difficulty swallowing (dysphagia), and odynophagia (painful swallowing). Flexible laryngoscopy can reveal a submucosal mass arising from the posterior pharyngeal wall, which is characteristic of Zenker's diverticulum.

Correct Answer: A

Rationale: Sherry is a type of fortified wine produced in Spain. It is not associated with the development of hyperkalemia, which is a condition characterized by high levels of potassium in the blood. Hyperkalemia is commonly caused by kidney dysfunction, certain medications, or excessive intake of potassium-rich foods. Drinking Sherry is not likely to cause hyperkalemia. On the other hand, Sherry consumption can potentially contribute to tooth decay, gastric ulcers, and rectal bleeding due to its acidity and alcohol content.

Correct Answer: A

Rationale: While it is important for nurse leaders to seek input and feedback from staff members, the inappropriate aspect of this action lies in the lack of clarity. The option contains a typographical error "natter" instead of "matter," which may lead to confusion and hinder effective communication. Additionally, the word choice of "opinion" instead of a more structured and strategic approach like "feedback" or "input" could be improved for professional communication in the workplace. Therefore, this action may not be considered appropriate in a work setting due to potential misunderstandings that can arise from the lack of clarity in communication.
