NSG3100 Exam 2 Questions & Answers 2026/2027 | 250+ Questions | Vital Signs, Infection Control, PPE, Wound Care, Pressure Injuries & Braden Scale

This NSG3100 Exam 2 2026/2027 study guide contains 250+ questions and answers across 55 pages, providing extensive review of fundamental nursing concepts involving vital signs, thermoregulation, pulse and respiratory assessment, blood pressure, oxygen saturation, immunity, infection control, medical and surgical asepsis, wound healing, pressure injuries, Braden Scale assessment, wound dressings, drains, and heat and cold therapy. The document is presented as already graded A+ and uses a direct question-and-answer structure that supports Exam 2 revision, active recall, self-testing, and review of clinical nursing procedures. The document identifies the course as NSG3100 and the academic period as 2026/2027, but no university name appears in the uploaded material; therefore, an institution should not be added without verification. The first major section provides detailed coverage of vital signs and nursing assessment. Topics include pulse oximetry, baseline vital signs, adult and older-adult temperature, pulse, respiration, oxygen saturation and blood-pressure ranges, delegation of vital-sign measurement to UAPs, and the nurse's responsibility for interpretation. Thermoregulation content examines the hypothalamus, metabolism, skin, circadian rhythms, exercise, hormones, stress, smoking, fever, hypothermia, heat exhaustion, heatstroke, frostbite, and nursing interventions for altered body temperature. The material also compares oral, rectal, axillary, tympanic, temporal artery, esophageal, and pulmonary artery temperature measurements and reviews appropriate indications and contraindications for different measurement sites. Cardiovascular and respiratory assessment receives substantial attention. Students review apical and peripheral pulses, pulse deficit, dysrhythmias, pulse intensity, tachycardia, hypoxemia, hypercapnia, eupnea, hypoventilation, hyperventilation, apnea, dyspnea, and orthopnea. The document identifies common pulse sites such as the temporal, carotid, brachial, radial, femoral, popliteal, posterior tibial, and dorsalis pedis arteries. Blood-pressure material covers hypotension, orthostatic hypotension, factors influencing blood pressure, appropriate cuff sizing, patient positioning, electronic blood-pressure measurement, and categories of elevated blood pressure and hypertension. Another extensive section concentrates on immunity, infection prevention, and transmission-based precautions. The questions distinguish innate and adaptive immunity, humoral and cellular immunity, immunologic memory, passive immunity, antigens, inflammatory responses, and the body's natural defenses. Students review all six components of the chain of infection, portals of entry and exit, susceptible hosts, healthcare-associated infections, endogenous and exogenous infections, and contact, droplet, airborne, vehicle, and vector-borne transmission. The guide includes examples involving tuberculosis, measles, varicella, pneumonia, pertussis, mumps, rubella, C. difficile, MRSA, herpes, scabies, and impetigo. The infection-control material further addresses hand hygiene, PPE, isolation precautions, protective isolation, surgical hand scrubbing, cluster care, medical asepsis, surgical asepsis, disinfection, and sterilization. Students can review PPE requirements for contact, droplet, and airborne precautions as well as the document's sequences for donning and removing PPE. It also discusses neutropenic patients, infection risks in older adults, localized versus systemic infection, antimicrobial-resistant organisms, and laboratory indicators associated with inflammation and infection. Approximately the latter half of the document provides intensive review of skin integrity, wound assessment, and wound healing. It distinguishes open and closed wounds; superficial, partial-thickness, and full-thickness wounds; clean, clean-contaminated, contaminated, infected, and colonized wounds; and acute versus chronic wounds. Students review primary, secondary, and tertiary intention, the inflammatory, proliferative, and maturation phases of healing, angiogenesis, granulation tissue, and factors that interfere with healing such as age, diabetes, infection, nutrition, vascular disease, medications, and excessive moisture. Complications include dehiscence, evisceration, fistulas, burns, medical adhesive-related skin injury, moisture-associated skin damage, and incontinence-associated dermatitis. A particularly important exam area is pressure-injury assessment and staging. The resource reviews Stage 1 non-blanchable erythema, Stage 2 partial-thickness skin loss, Stage 3 full-thickness skin loss, Stage 4 full-thickness skin and tissue loss, unstageable pressure injuries, and deep tissue pressure injuries. Students also study pressure, friction, shear, ischemia, medical-device-related injuries, bony prominences, nutritional risk, tunneling, undermining, and focused wound assessment. The Braden Scale section covers sensory perception, moisture, activity, mobility, nutrition, and friction/shear and explains that lower scores indicate greater pressure-injury risk. The final sections address wound drainage, debridement, dressings, drains, and wound therapies. Students differentiate serous, serosanguineous, sanguineous, purulent, and purosanguineous drainage and review wound measurement and documentation. Debridement methods include sharp, mechanical, chemical, autolytic, and biologic approaches. Dressing content covers gauze, transparent films, hydrocolloids, foams, and alginates, while drainage systems include Jackson-Pratt, Hemovac, and Penrose drains. Additional material addresses negative-pressure wound therapy, sutures, bandages, the five Ps of neurovascular assessment, wound cultures, irrigation, and indications and contraindications for heat and cold therapy. This document is particularly relevant for NSG3100 students, BSN students, pre-licensure nursing students, fundamentals of nursing students, nursing skills students, clinical nursing students, health assessment students, and nursing students preparing for exams on vital signs, infection prevention, asepsis, pressure injuries, wound assessment, and wound management. Its extensive question-and-answer format also makes it useful for active recall, last-minute Exam 2 review, clinical-skills reinforcement, and identifying areas that require additional study.
