Rationale: Maternal anxiety can contribute to a prolonged latent phase during labor. Stress and anxiety can trigger the release of stress hormones such as adrenaline, which can interfere with the production of oxytocin, the hormone responsible for initiating contractions. This can result in irregular and ineffective contractions, leading to a prolonged latent phase. It is important for the nurse to assess the woman's anxiety levels and provide reassurance and support to help facilitate the progression of labor.

Rationale: A correlational research design is most appropriate when the aim is to find a relationship between two variables. Correlational studies examine how variables are related to each other without manipulating them. This design allows researchers to determine the strength and direction of the relationship between variables, providing valuable insights into the potential associations between different factors. Phenomenological studies focus on understanding individuals' experiences, exploratory studies investigate a topic without predefined hypotheses, and experimental studies involve manipulating variables to observe their effects. Therefore, in the context of aiming to find a relationship between two variables, a correlational research design is the most suitable choice.

Correct Answer: B

Rationale: The nurse's priority action when noticing an abnormal heart rhythm on the patient's cardiac monitor during surgery is to assess the patient's vital signs and symptoms. This is important because the nurse needs to gather more information about the patient's condition to determine the significance of the abnormal rhythm and the potential impact on the patient's health. By assessing the vital signs and symptoms, the nurse can obtain a more complete picture of the situation and make informed decisions about the next steps in caring for the patient. Once the assessment is done, appropriate actions such as administering medication or notifying the anesthesiologist can be taken based on the findings.
