A nurse is caring for a client who has burns to approximately 50% of their body. Which of the following physiological changes related to the burns should the nurse anticipate? (Select all that apply.)
Decreased plasma volume
Diuresis
Hypermagnesemia
Capillary leak
Loss of protein
Correct Answer : A,D,E
A. Decreased plasma volume: Burn injuries cause a significant inflammatory response, leading to fluid shifts from the intravascular space to the interstitial space. This results in hypovolemia and decreased plasma volume, especially during the acute phase of burns.
B. Diuresis: Diuresis typically occurs after fluid resuscitation and stabilization of the client (in the later phase of burn recovery). In the initial phase, oliguria is more common due to hypovolemia and reduced renal perfusion.
C. Hypermagnesemia: Hypermagnesemia is not typically associated with burn injuries. Instead, clients with burns often experience hypomagnesemia due to fluid shifts, protein loss, and increased renal losses.
D. Capillary leak: Burn injuries lead to a systemic inflammatory response, causing capillary leak syndrome. This increases vascular permeability, allowing fluid, electrolytes, and proteins to leak into the interstitial spaces, contributing to edema and hypovolemia.
E. Loss of protein: Proteins are lost through damaged capillaries and open burn wounds, contributing to decreased oncotic pressure, edema, and a need for aggressive nutritional support to promote healing and recovery.

Correct Answer is B
Explanation
A. Loose connective tissue:
Melanocytes are not typically found in loose connective tissue. Their primary location is within the epidermis, specifically in the basal layer, where they interact with keratinocytes to produce melanin and contribute to skin color. Loose connective tissue contains collagen and elastin fibers, as well as fibroblasts, but it does not house melanocytes.
B. Epidermis:
This is the correct answer. Melanocytes are primarily located in the basal layer of the epidermis, which is the deepest layer of the epidermis. These cells produce melanin, a pigment that helps protect the skin from UV radiation and determines skin color. Melanocytes are interspersed among keratinocytes in the epidermis and transfer melanin to keratinocytes to provide skin pigmentation.
C. Dermis:
The dermis is the layer of skin beneath the epidermis and consists of connective tissue, blood vessels, nerves, hair follicles, and sweat glands. While the dermis plays a crucial role in supporting and nourishing the epidermis, melanocytes are not primarily located in the dermis. They are confined to the basal layer of the epidermis.
D. Superficial fascia:
The superficial fascia, also known as the subcutaneous tissue or hypodermis, lies beneath the dermis and consists of adipose (fat) tissue and connective tissue. It provides insulation, energy storage, and cushioning for underlying structures. However, melanocytes are not typically found in the superficial fascia. They are restricted to the epidermis, specifically the basal layer, where they carry out their function of melanin production.
Correct Answer is D
Explanation
A. Evidence-based practice:
Evidence-based practice (EBP) involves integrating the best available evidence from research, clinical expertise, and patient preferences and values to inform nursing practice. In perioperative nursing, EBP is important for making informed decisions about preoperative, intraoperative, and postoperative care protocols. For example, using evidence-based guidelines for surgical site infection prevention, pain management strategies, and postoperative care protocols can improve patient outcomes and safety.
B. Informatics:
Informatics refers to the use of information technology and data management systems to support nursing practice, education, research, and patient care. In perioperative nursing, informatics plays a crucial role in managing electronic health records (EHRs), accessing patient data, documenting care, and communicating with interdisciplinary team members. It also includes utilizing perioperative information systems for surgical scheduling, anesthesia records, and tracking patient progress during surgery.
C. Quality improvement:
Quality improvement (QI) involves systematic processes to monitor, assess, and improve the quality of healthcare services. In perioperative nursing, QI initiatives focus on enhancing patient safety, optimizing surgical outcomes, reducing complications, and improving efficiency in perioperative processes. Nurses participate in QI projects by analyzing data, identifying areas for improvement, implementing evidence-based practices, and evaluating the impact of interventions on patient care and outcomes.
D. Safety:
Safety is a fundamental QSEN competency, particularly critical in perioperative nursing care. Perioperative nurses are responsible for ensuring the safety of patients during all phases of surgery, including preoperative assessment, intraoperative care, and postoperative recovery. This includes measures such as verifying patient identity and surgical site, preventing surgical errors (e.g., wrong-site surgery), maintaining aseptic techniques to prevent infections, preventing falls and injuries, managing anesthesia safely, and adhering to protocols for safe medication administration and equipment use.
