Adult Health Nursing Study Guide Answers

Correct Answer: B

Rationale: The nurse should monitor the International Normalized Ratio (INR) closely during anticoagulant therapy for the prevention of VTE. The INR measures the clotting ability of the blood and is used to monitor the effectiveness of anticoagulant therapy, such as warfarin. Maintaining the INR within the target therapeutic range is crucial to prevent both excessive bleeding due to over-anticoagulation and clotting events due to under-anticoagulation. Close monitoring of the INR helps healthcare providers adjust the anticoagulant dosage as needed to ensure optimal therapeutic outcomes and minimize risks. Platelet count, serum sodium levels, and blood urea nitrogen (BUN) are important laboratory parameters to monitor for other medical conditions but are not specific to anticoagulant therapy.

Correct Answer: C

Rationale: Battery occurs when there is an intentional harmful or offensive contact with a person without their consent. In this scenario, Nurse Edna applied a body restraint to the patient without the doctor's order, which constitutes unauthorized physical contact. The patient did not give consent for the restraint, and Nurse Edna's action could be considered battery. It is important for healthcare providers to obtain proper authorization before using any form of physical restraint on a patient to avoid legal implications such as battery.

Correct Answer: A

Rationale: Continuing Professional Development such as post-graduate study is the best strategy among the options provided for addressing short staffing in the hospital. By encouraging nurses to pursue post-graduate studies, Chief Nurse Cirila is investing in the long-term growth and development of her nursing workforce. Post-graduate studies can enhance the knowledge, skills, and expertise of nurses, making them more competent in their roles. This can lead to improved patient care outcomes, increased job satisfaction among nurses, and ultimately help in retaining and attracting talent in the hospital. Additionally, supporting nurses in their professional development can boost morale and motivation, which are crucial factors in addressing short staffing issues.

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: C

Rationale: In a conscious trauma patient with a suspected head injury, maintaining cervical spine immobilization is crucial. The presence of a head injury raises concerns for potential concomitant cervical spine injury. Therefore, it is vital to prevent any movement of the cervical spine to avoid exacerbating a potential spinal cord injury. Maintaining immobilization involves stabilizing the patient's head and neck in a neutral position until appropriate imaging studies can assess the extent of any spinal injury. This action helps prevent further harm and ensures the safety of the patient during assessment and management of their injuries.
