and tumor necrosis factor-alpha (TNF-α) during the acute phase response?

Correct Answer: A

Rationale: Macrophages are the primary cells responsible for producing tumor necrosis factor-alpha (TNF-α) during the acute phase response. TNF-α is a pro-inflammatory cytokine that plays a critical role in initiating and propagating the inflammatory response. Macrophages secrete TNF-α in response to infection, injury, or other inflammatory stimuli, contributing to the recruitment of immune cells and the activation of additional inflammatory pathways. In the context of the acute phase response, macrophages are key mediators of the immune response and play a crucial role in host defense mechanisms.

Correct Answer: B

Rationale: A severe headache is a classic sign of a hemorrhagic stroke. Hemorrhagic stroke occurs when a blood vessel in the brain ruptures and causes bleeding. This bleeding can lead to increased pressure within the skull, resulting in a sudden and severe headache. Other symptoms of a hemorrhagic stroke may include nausea, vomiting, sudden weakness or numbness on one side of the body, difficulty speaking or understanding speech, and loss of coordination. It is important to seek immediate medical attention if someone is experiencing symptoms of a stroke, including a severe headache, as prompt treatment is crucial in minimizing damage and improving outcomes.

Correct Answer: C

Rationale: The main source of nutrition for the baby during pregnancy is the placenta. The placenta is an organ that develops inside the uterus during pregnancy and provides essential nutrients and oxygen from the mother's blood to the baby through the umbilical cord. It acts as a barrier, protecting the baby from harmful substances while allowing necessary nutrients to pass through. The amniotic fluid serves as a protective cushion for the baby, the uterus provides the space for the baby to grow, and chorionic villi are small, hair-like structures on the placenta that aid in the exchange of nutrients and waste between the mother and the baby. However, the primary source of nutrition for the baby is the placenta, making option C the correct answer in this scenario.

Correct Answer: D

Rationale: The correct answer is D, issuing a permit for the opening of nursing programs in the country. The PRC-Board of Nursing (PR-BON) in the Philippines primarily focuses on regulating nursing practice and ensuring the quality and standards of nursing care provided in the country. While they have the authority to oversee aspects such as certification of registered nurses, enforcing quality standards, and monitoring proper conduct of nurses, the responsibility of issuing permits for the opening of nursing programs typically falls under the jurisdiction of other relevant educational or accrediting bodies.

Correct Answer: C

Rationale: Osteoporosis is a condition characterized by an imbalance between bone resorption (breakdown of bone tissue) and bone formation, leading to bone thinning and increased risk of fractures. In osteoporosis, bones become weak and porous, making them more prone to fractures even with minor trauma. This condition is common in postmenopausal women and older individuals. Risk factors for osteoporosis include age, gender, family history, lack of physical activity, low calcium and vitamin D intake, smoking, excessive alcohol consumption, and certain medications. Treatment typically involves lifestyle modifications, including adequate calcium and vitamin D intake, weight-bearing exercises, and sometimes medication to help slow down bone loss and reduce fracture risk. Early detection and management of osteoporosis are crucial to prevent fractures and maintain bone health.

Correct Answer: D

Rationale: Administering oxygen inhalation is the priority nursing action for a patient presenting with clinical manifestations related to endocrine disorders. Patients with hyperthyroidism, Cushing syndrome, and hypothyroidism can all experience respiratory distress due to various reasons such as thyroid storm, adrenal crisis, or myxedema coma. Oxygen inhalation helps improve oxygenation and tissue perfusion, providing immediate support to the patient's respiratory system. It is crucial to ensure adequate oxygenation before addressing other assessments or interventions. Once the patient's breathing is stabilized, further assessments and treatments can be initiated as necessary.

Correct Answer: C

Rationale: In the context of CO-PAR (Community Organizing Participatory Action Research), the most important role of the public health nurse is being an expert. Public health nurses are expected to have specialized knowledge and skills in the field of public health, allowing them to provide evidence-based guidance and interventions to support community health initiatives. As an expert, the public health nurse can assess community needs, develop appropriate interventions, educate community members on health promotion and disease prevention, and evaluate the effectiveness of implemented programs. By utilizing their expertise, public health nurses can effectively contribute to improving the health outcomes and well-being of the community they serve.

Correct Answer: B

Rationale: Tilt back Claudia's head slightly would have been the correct action to prevent her from blinking during eye drop instillation. By tilting her head back, you create a more stable position for instilling the eye drops, reducing the likelihood of accidental contact with her eyelid. Additionally, tilting the head back slightly helps in making it easier for the drops to enter the eye and stay within the conjunctival sac, improving the efficacy of the medication.
