You cannot open Claudia's eyes due to dried crust. Which of the following actions would you do?

Correct Answer: D

Rationale: The best course of action in this scenario is to place a warm wet washcloth over Claudia's eyes for at least three minutes. This will help soften and loosen the dried crust, making it easier to gently clean her eyes and open them. Applying eye drops or ointment may not be effective if the crust is blocking her eyes completely. By using a warm wet washcloth, you can improve the ability to clean her eyes effectively and without causing discomfort.

Correct Answer: A

Rationale: Option A indicates an understanding of the normal psychosocial development of preschoolers. It reflects the fact that during this stage, children may demonstrate frustration and have temper tantrums as they strive for independence and attempt to do things by themselves. This behavior is a common part of their development as they learn self-control, autonomy, and decision-making skills. The other options do not directly relate to normal preschooler development but rather touch upon separate issues such as separation anxiety, possessiveness, and social behaviors that are not necessarily abnormal for preschoolers.

Correct Answer: C

Rationale: An assumption is a belief or statement that is accepted as true without proof. In this case, the statement suggests a belief that the length of service does not affect the degree of patient safety practices among staff nurses, without providing evidence or data to support this claim. It is an assumption about the relationship between two variables without a proper basis or evidence to back it up, making it an example of an assumption.

Correct Answer: A

Rationale: By randomly selecting individuals in the community for the project, Nurse Mary is upholding the ethical principle of autonomy. Autonomy refers to respecting individuals' right to make their own decisions and choices. In this scenario, Nurse Mary is not imposing her own preferences or biases but rather allowing individuals in the community to have an equal opportunity to participate in the project. Random selection ensures that the process is fair and gives everyone an equal chance to be involved, respecting their autonomy.

Correct Answer: A

Rationale: T helper cells (Th cells) are primarily responsible for coordinating and regulating immune responses by producing cytokines that direct the activities of other immune cells. These cytokines help in activating cytotoxic T cells, B cells, macrophages, and other cells involved in the immune response. Th cells play a crucial role in mounting an effective immune response against infections and diseases by providing the necessary signals to activate and control various immune cells. Thus, T helper cells are considered the central coordinators of the immune system.

Correct Answer: A

Rationale: The FIRST action of the nurse should be to reassess the client experiencing dyspnea despite continuous oxygen therapy. Reassessment would involve checking the client's respiratory status, oxygen saturation levels, vital signs, and overall condition to gather more information about the situation. This will help the nurse identify any potential causes of the dyspnea and determine the appropriate next steps for intervention. Assessing the client before proceeding with any other actions is crucial in providing safe and effective care.

Correct Answer: C

Rationale: It is crucial to ensure that the autoclave is functioning properly to achieve proper sterilization of surgical instruments. If the autoclave is not reaching the required temperature, it signifies a technical issue that needs to be addressed promptly. The nurse should notify the sterile processing department immediately and request maintenance to investigate and resolve the problem. Continuing with sterilization without addressing the temperature issue can compromise the effectiveness of sterilization and pose a risk of infection to patients. Adjusting the settings on the autoclave or using an alternative method of sterilization are not appropriate actions in this situation.

Correct Answer: C

Rationale: Uterine rupture is a severe obstetric complication that requires prompt and decisive management to prevent adverse outcomes for both the mother and the baby. In cases of uterine rupture leading to fetal distress and maternal hemorrhage, performing an emergency cesarean section is crucial. This intervention allows for rapid delivery of the baby, relieving the distress on the fetus and enabling immediate access to manage the maternal hemorrhage. By performing a timely cesarean section, healthcare providers can expedite the delivery process and effectively address both the fetal and maternal complications associated with uterine rupture. This intervention is essential in saving lives and reducing the risk of further complications in such a critical obstetric emergency.

Correct Answer: B

Rationale: The first step in the qualitative research process is typically conducting a review of existing literature on the topic of interest. This involves exploring existing research studies, theories, and findings related to the area being studied. By reviewing the literature, researchers can gain a better understanding of the current knowledge and identify gaps in the existing research that their study can address. This step helps researchers define the research question, refine the study design, and establish a strong theoretical framework for the study.
