By providing measures to reduce skin breakdown, how does the nurse break the chain of infection?

Correct Answer: B

Rationale: In this scenario, the correct answer is B) Maintaining the integrity of a portal of entry. By providing measures to reduce skin breakdown, such as keeping the skin clean, dry, and intact, the nurse is effectively preventing pathogens from entering the body through breaks in the skin. This action disrupts the chain of infection at the portal of entry stage, thereby reducing the risk of infection transmission. Option A) Sterilizing the area to reduce the reservoir risk is incorrect because sterilizing the area would target eliminating pathogens at the reservoir stage, not necessarily at the portal of entry. The focus should be on preventing entry rather than reducing reservoir risk. Option C) Creating a reservoir to decrease the risk of infection is incorrect because creating a reservoir would actually increase the risk of infection by providing a source for pathogens to multiply and spread. Option D) Creating a susceptible host is incorrect because the goal is to prevent infection by reducing the opportunity for pathogens to enter the body, not by making the host more susceptible to infection. In an educational context, understanding how infection control measures work to break the chain of infection is crucial for healthcare professionals to provide effective care and prevent the spread of infections in healthcare settings. By emphasizing the importance of maintaining skin integrity and implementing proper infection prevention protocols, nurses can play a significant role in reducing the risk of healthcare-associated infections.

Correct Answer: A

Rationale: The correct answer is option A) A herniated disk in the diseased joint. Crepitus, an audible grating sound, is commonly associated with osteoarthritis due to the roughening of the cartilage surfaces in the affected joints. When the joint moves, the rough surfaces rub together, producing the characteristic sound. Option B) Pieces of bone and cartilage floating is incorrect because while loose bodies in the joint can cause pain and mechanical symptoms, they do not typically produce crepitus. Option C) Popping bursae from standing is incorrect as bursitis, inflammation of the bursae, can cause swelling and pain but not crepitus. Option D) Years of an autoimmune process is incorrect as autoimmune processes like rheumatoid arthritis may cause joint inflammation and damage, but they do not directly lead to crepitus. Understanding the specific sound manifestations in osteoarthritis aids nurses in accurate assessment and diagnosis, enabling appropriate interventions to manage the condition effectively. This knowledge is crucial in providing holistic care to clients with musculoskeletal disorders.

Correct Answer: D

Rationale: In managing chronic pain in clients with rheumatoid arthritis, it is essential to employ evidence-based nonpharmacological methods. The correct answer, option D, "Ice for 2 hours at a time," is not recommended for managing rheumatoid arthritis pain. Ice application for such an extended period can potentially lead to skin damage, worsen joint stiffness, and exacerbate pain in individuals with arthritis. On the other hand, options A, B, and C are appropriate nonpharmacological methods for managing chronic pain in rheumatoid arthritis. Adequate rest helps in reducing inflammation and promoting healing. Heat application for 20-30 minutes can help to relax muscles, improve circulation, and reduce pain. Hot showers can also provide similar benefits in terms of muscle relaxation and pain relief. Educationally, it is crucial for healthcare providers to understand the appropriate use of nonpharmacological pain management strategies in rheumatoid arthritis to optimize patient outcomes. By avoiding practices that can potentially harm the patient, like prolonged ice application, healthcare professionals can ensure safe and effective pain management for individuals with rheumatoid arthritis.

Correct Answer: B

Rationale: In this scenario, the correct answer is B) Assessment. The nurse noticing a new area of skin breakdown near a dressing site indicates the need for a thorough assessment of the patient's skin integrity. Assessment is the first step in the nursing process, where data is collected, organized, and documented to identify actual or potential health issues. Option A) Diagnosis comes after the assessment phase. It involves analyzing the data collected during assessment to identify the patient's health problems and needs. In this case, the nurse has not yet reached the stage of making a diagnosis based on the skin breakdown observation. Option C) Implementation is the phase where nursing interventions are carried out based on the identified nursing diagnoses. Since the nurse has just observed the skin breakdown, there is no intervention implemented yet, ruling out this option. Option D) Evaluation is the final phase of the nursing process where the nurse assesses the outcomes of the interventions implemented. In this scenario, the nurse is still in the initial stages of data collection and assessment, so evaluation is not yet applicable. Understanding the nursing process is crucial for providing effective patient care. By recognizing the correct phase of the process based on specific patient cues, nurses can ensure comprehensive and individualized care tailored to the patient's needs. This question highlights the importance of keen observation skills and the sequential nature of the nursing process in delivering quality patient care.

Correct Answer: D

Rationale: The correct answer to the question is D) Stage 4. At 7 weeks post-fracture, the bone healing process enters Stage 4, known as the "remodeling stage." During this phase, the callus formed at the fracture site is gradually replaced by mature bone tissue through the action of osteoclasts and osteoblasts. This transformation strengthens the bone and restores its original shape and structure. Option A) Stage 3 is incorrect because Stage 3 is the "callus formation stage," which occurs immediately after the fracture and involves the formation of a soft callus made of fibrous tissue and cartilage. Option B) Stage 5 is incorrect because there are typically only four stages in the bone healing process, so Stage 5 is not a valid stage in this context. Option C) Stage 1 is incorrect because Stage 1 is the "hematoma formation stage," which is the initial response to the fracture where blood clotting and inflammation occur. Understanding the stages of bone healing is crucial for healthcare professionals involved in the care of patients with fractures. Knowing the timeline and processes involved in bone healing helps in assessing the progress of healing, determining appropriate interventions, and managing complications that may arise during the recovery process.
