One evening, Sonny complained of dyspnea despite continuous oxygen therapy. What should be the FIRST action of the nurse?

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: D

Rationale: Scabies is caused by an infestation of the microscopic mite Sarcoptes scabiei. This parasitic mite burrows into the upper layer of the skin, where it lays eggs and causes intense itching and skin irritation. The transmission of scabies usually occurs through close and prolonged skin-to-skin contact with an infested person. Unlike viruses, bacteria, and fungi, which are microorganisms that can also cause skin infections, scabies specifically refers to an infestation by a parasitic mite.

Correct Answer: B

Rationale: This statement indicates a need for further instructions because drinking milk between meals may worsen heartburn for some individuals. Milk can temporarily neutralize stomach acid, but it can also stimulate acid production in the stomach leading to increased heartburn symptoms. Therefore, Nurse Harper should provide more guidance on appropriate dietary choices for managing heartburn, such as avoiding trigger foods like fatty or spicy foods, eating small, frequent meals, and not lying down immediately after eating.

Correct Answer: A

Rationale: Natural killer (NK) cells play a vital role in the innate immune response by identifying and eliminating virus-infected cells, as well as tumor cells, without the need for prior exposure or activation. NK cells are able to detect abnormal cells by recognizing changes in the cell surface molecules, such as downregulation of MHC class I molecules. Once activated, NK cells release cytotoxic granules containing perforin and granzyme, leading to the destruction of the target cell. This direct killing mechanism is crucial for controlling viral infections and preventing the development of tumors. NK cells do not produce antibodies (option B), present antigens to T cells (option C), or release cytokines to recruit other immune cells (option D) as their primary function in the immune response.

Correct Answer: A

Rationale: When collecting evidence from a rape victim, it is important to handle the victim's clothing properly to preserve any potential evidence. The preferred method is to remove the clothing and place them in a paper bag. Paper bags are used in order to prevent the alteration or degradation of any DNA evidence that may be present on the clothing. Paper bags allow the clothing to breathe and prevent the growth of mold or other contaminants that can occur in plastic bags or trash bags. Additionally, paper bags help preserve trace evidence such as fibers or hairs that may be crucial in the investigation of the case. It is essential to handle and store the clothing correctly to maintain the integrity of the evidence for the investigation and potential prosecution.

Correct Answer: B

Rationale: The formulation of a vision and mission statement in a health facility is an essential aspect of leadership and management.

It helps in aligning individual goals with organizational objectives, fostering teamwork, and enhancing overall performance. Effective leadership and management ensure that the vision and mission are communicated effectively, understood by all stakeholders, and implemented throughout the organization to achieve quality standards. By setting the tone for organizational culture and values, leadership and management play a crucial role in shaping the quality of care and services provided by the health facility.

Rationale: The best approach for the nurse in this situation is to listen actively to the patient's religious beliefs, respect their autonomy, and explore alternative treatment options. It is important for the nurse to understand and acknowledge the patient's perspective, even if it conflicts with the recommended treatment plan. By showing respect for the patient's beliefs and involving them in the decision-making process, the nurse can work collaboratively with the patient to find a solution that aligns with their religious beliefs while also addressing their medical needs. This approach promotes patient-centered care and helps build a trusting and therapeutic relationship between the nurse and the patient.

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.
