Adult Health Nursing Quizlet Final

Correct Answer: C

Rationale: The description provided is classical for fungal keratitis. Fungal keratitis typically presents with a yellowish-white spot on the cornea, often surrounded by a ring of inflammation. Branching, filamentous opacities extending from the corneal lesion are commonly seen on slit-lamp examination in cases of fungal keratitis. This condition is often associated with risk factors such as trauma with organic material or contact lens wear. Prompt diagnosis and treatment with antifungal agents are crucial in managing fungal keratitis to prevent potential complications.

Correct Answer: B

Rationale: Cultural competence is the process of acquiring specific knowledge, skills, and attitudes to effectively work with individuals from diverse cultural backgrounds. It involves understanding and respecting the values, beliefs, languages, and practices of different cultures in order to provide appropriate care and services. Cultural competence goes beyond just learning about different cultures; it requires the development of skills and attitudes that promote effective communication, understanding, and collaboration with individuals of diverse backgrounds. This includes being aware of one's own biases, being open-minded, and adapting practices to be inclusive and respectful of cultural differences. Ultimately, cultural competence is essential in providing high-quality, respectful, and effective care to clients from various cultural backgrounds.

Correct Answer: C

Rationale: Neuman's adaptation model, also known as the Neuman Systems Model, is a nursing theory that focuses on how individuals respond to stressors in their environment. The model views individuals as being in a constant state of dynamic equilibrium, where they are interacting with stressors that can disrupt their normal functioning. Nursing care, according to this model, is aimed at helping individuals maintain or restore their optimal level of wellness by assisting them in adapting to these stressors. Therefore, Nurse Sandy's selection of a framework that emphasizes the constant relationship between humans and stressors in the environment aligns best with Neuman's adaptation model.

Correct Answer: C

Rationale: Humoral immunity is primarily responsible for protecting against infections by pathogens like viruses. In the case of the hepatitis B virus (HBV), the individual is exposed to the virus and develops immunity, which is typically mediated by antibodies produced by B cells. These antibodies circulate in the blood and can neutralize the virus, preventing future infections. This type of immunity is known as humoral immunity, as it involves the production of antibodies that target specific antigens, such as those present on the surface of the hepatitis B virus. In contrast, passive immunity is when antibodies are transferred from an external source, innate immunity provides immediate, non-specific defenses against pathogens, and cell-mediated immunity involves the activation of T cells to combat intracellular pathogens.

Correct Answer: A

Rationale: ** In a patient with ARDS, the priority intervention to manage respiratory failure is to initiate lung-protective mechanical ventilation with low tidal volume. ARDS is characterized by widespread inflammation and injury to the alveoli, leading to impaired gas exchange and severe hypoxemia. Lung-protective ventilation strategies aim to minimize ventilator-induced lung injury by using lower tidal volumes (around 6 mL/kg of predicted body weight) to reduce barotrauma and volutrauma.
