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: Checking the flow of oxygen is the priority action because it ensures that Sonny is receiving the correct amount of oxygen prescribed by the healthcare provider. Before connecting the flow meter to the oxygen outlet, turning on the oxygen, or attaching the humidifier, it is crucial to verify that the flow rate is appropriate for Sonny's condition. Monitoring and adjusting the oxygen flow will help maintain the desired oxygen saturation levels and prevent potential complications related to oxygen therapy.

Correct Answer: C

Rationale: Choosing option C, asking the patient about their cultural beliefs and preferences related to pain, demonstrates cultural competence in pain assessment. Pain experiences can vary greatly across different cultures, and a patient's cultural background can influence how they perceive and express pain. By inquiring about the patient's cultural beliefs and preferences, the nurse can gain a better understanding of the patient's perspective on pain. This information is crucial for providing individualized and culturally sensitive pain management interventions. It also shows respect for the patient's unique cultural background and helps build a trusting and collaborative relationship between the nurse and the patient.

Correct Answer: A

Rationale: The BEST position for a patient in shock is the modified Trendelenburg position. In this position, the patient's legs are elevated above the level of the heart to enhance blood flow back to the heart and vital organs. Placing the patient in the modified Trendelenburg position helps increase venous return, improves cardiac output, and promotes perfusion to vital organs, which can be crucial in managing shock. This position can help stabilize the patient's condition while awaiting further medical intervention.

Correct Answer: D

Rationale: When performing an intramuscular (IM) injection, the nurse should insert the needle at a 90-degree angle into the muscle. This angle helps ensure proper and deep penetration into the muscle tissue for effective administration of the medication. It also helps prevent leakage or tissue damage at the injection site. Additionally, inserting the needle at a 90-degree angle facilitates accurate delivery of the medication into the muscle where it can be absorbed properly. Therefore, selecting the correct angle for inserting the needle is critical in ensuring the success and effectiveness of the IM injection.
