Which of the following is a physiologic result of wound treatment with ultraviolet radiation?

Correct Answer: C

Rationale: In wound treatment with ultraviolet radiation, the correct physiologic result is increased vascularization of wound margins (Option C). This is because ultraviolet radiation promotes angiogenesis, the formation of new blood vessels, which aids in delivering essential nutrients and oxygen to the wound site, facilitating the healing process. Option A, decreased Vitamin D production, is incorrect as ultraviolet radiation actually stimulates the production of Vitamin D in the skin. Option B, increased bacterial growth, is incorrect as UV radiation has antimicrobial properties and can help reduce bacterial load on wounds. Option D, decreased calcium metabolism, is also incorrect as UV radiation plays a role in Vitamin D synthesis, which is crucial for calcium absorption and metabolism. In an educational context, understanding the effects of different wound treatments on the body's physiological processes is essential for healthcare professionals involved in wound care. Knowledge of how ultraviolet radiation influences wound healing can help in making informed decisions regarding the most appropriate treatment modalities for different types of wounds. Understanding these concepts is crucial for providing optimal patient care and achieving positive outcomes in wound management.

Correct Answer: B

Rationale: The correct answer is B) Palpating the kidneys and uterus. The bimanual palpation technique involves using both hands to assess deep structures or organs that cannot be easily palpated with one hand alone. When palpating the kidneys and uterus, this technique allows the nurse to provide support with one hand while using the other hand to feel for the size, shape, and tenderness of these organs. Option A) Palpating the thorax of an infant typically does not require bimanual palpation as the thorax is a superficial structure that can be adequately assessed with one hand. Option C) Assessing pulsations and vibrations can usually be done effectively with a single hand and does not necessarily require the use of bimanual palpation. Option D) Assessing the presence of tenderness and pain can also often be accomplished with a single hand, especially in areas where structures are more superficial. In an educational context, understanding the appropriate use of bimanual palpation is crucial for nurses to accurately assess deep structures and organs. This technique ensures thorough and comprehensive assessments, especially in situations where precise palpation is necessary, such as when examining the kidneys and uterus. Nurses must be knowledgeable about different palpation techniques to provide optimal patient care.

Correct Answer: B

Rationale: When blood is exposed to the environment of the stomach, it often resembles 'coffee grounds.' This is not always recognized by patients as blood, so it is important to inquire about this. This symptom is not common in cholecystitis, and the other possibilities occur lower in the intestine. It should be noted that conversely, rapid bleeding from the stomach or other upper gastrointestinal source can produce bright red blood in the stool. Do not rule out proximal bleeding on the basis of the absence of 'coffee grounds.' Likewise, bright red blood seen with emesis may originate from the stomach. Black, sticky stools also can accompany upper GI bleeding.

Correct Answer: B

Rationale: In this scenario, the correct answer is B) 3+. Bounding pulses indicate a significant increase in the strength and amplitude of the pulse, often associated with conditions like peripheral vascular disease. This strength is graded on a scale from 0 to 3, with 3+ representing the highest intensity or bounding pulse. Option A) 0 is incorrect because it indicates an absent pulse, which is not the case in this scenario. Options C) 2+ and D) 1+ both represent pulses with varying degrees of strength, but they do not accurately describe the bounding nature of the pulses seen in peripheral vascular disease. Educationally, understanding how to assess and interpret pulses is crucial for healthcare providers, especially in patients with underlying cardiovascular conditions. Recognizing bounding pulses can provide valuable diagnostic information and guide appropriate interventions for the patient's care. It is essential for healthcare professionals to be proficient in assessing vital signs and recognizing abnormalities to provide optimal patient care.

Correct Answer: B

Rationale: In the context of a client with bacterial meningitis, the best choice for a hospital room is Option B) An isolation room three doors from the nurses' station. This option is correct because bacterial meningitis is highly contagious and requires strict isolation precautions to prevent the spread of infection to other patients and healthcare workers. Placing the client in an isolation room helps contain the infectious agent and reduces the risk of transmission. Option A) A private room down the hall from the nurses' station is not the best choice because it does not provide the necessary isolation needed for a client with bacterial meningitis. Option C) A semiprivate room with a 32-year-old client who has viral meningitis is also not appropriate as it can increase the risk of cross-infection between the two clients. Option D) A two-bed room with a client who previously had bacterial meningitis is not ideal as the client may still be a carrier of the bacteria and pose a risk of reinfection. From an educational standpoint, this scenario highlights the importance of understanding the specific isolation requirements for infectious diseases and the critical role of infection control measures in preventing the spread of communicable diseases in healthcare settings. Healthcare professionals must be knowledgeable about proper isolation protocols to ensure the safety of both patients and staff members.
