A patient presents with sudden-onset, painless vision loss in the right eye. Fundoscopic examination reveals a cherry-red spot at the macula and attenuated retinal vessels. Which of the following conditions is most likely responsible for this presentation?

Correct Answer: A

Rationale: The presentation described with sudden-onset, painless vision loss, a cherry-red spot at the macula, and attenuated retinal vessels is classic for central retinal artery occlusion (CRAO). CRAO occurs when the central retinal artery, which supplies blood to the inner retinal layers, becomes occluded. The cherry-red spot is due to the exposure of the underlying choroid, which still appears red as it is not affected by the blockage. Attenuated retinal vessels and a pale retina may also be seen due to ischemia. In contrast, central retinal vein occlusion (choice B) presents with sudden painless vision loss, retinal hemorrhages, dilated retinal veins, and cotton-wool spots. Retinal detachment (choice C) typically presents with flashes, floaters, and a curtain-like shadow across the vision. Acute angle-closure glaucoma (

Correct Answer: A

Rationale: In terms of social support therapy for a patient with Amyotrophic Lateral Sclerosis (ALS), the most appropriate and therapeutic option would be for the patient to live in the community with appropriate support, either independently or in a supervised setting. This approach allows the individual to maintain a sense of autonomy and independence while still having access to necessary support and care as needed. Living in the community promotes social interaction, engagement, and a sense of normalcy, which can contribute positively to the patient's mental well-being and overall quality of life. This approach also aligns with the principles of person-centered care, focusing on the individual's preferences, needs, and autonomy.

Correct Answer: C

Rationale: The salivary glands are responsible for the production of saliva, which aids in lubricating the oral cavity and initiating the digestion of carbohydrates. Saliva contains enzymes that begin the digestive process by breaking down carbohydrates into simpler sugars. The liver is involved in the production of bile, which aids in the digestion and absorption of fats. The gallbladder stores bile produced by the liver, which is released into the small intestine. The pancreas produces digestive enzymes that are released into the small intestine to aid in the digestion of proteins, fats, and carbohydrates.

Correct Answer: B

Rationale: Delegation by succession involves passing on responsibility and authority to a designated successor when the delegator is temporarily unavailable. In this scenario, the unit manager is planning to take her regular official business leave and has recommended her assistant unit manager to assume her position during her absence. This act follows the principle of succession, where the deputy or next in line is entrusted with the duties and decision-making power of the manager. This ensures a smooth transition of responsibilities and allows the operations to continue efficiently in the manager's absence.

Correct Answer: D

Rationale: Sonography, also known as ultrasound, is a non-invasive imaging technique that uses high-frequency sound waves to create images of structures inside the body. In the context of a patient who is pregnant, sonography is commonly used to assess the well-being of the fetus. It allows healthcare providers to monitor the growth and development of the fetus, evaluate the placenta, amniotic fluid levels, and detect any abnormalities that may be present.

Correct Answer: B

Rationale: Loop diuretics, such as furosemide, are potent diuretics commonly used to manage conditions like edema, heart failure, and hypertension. Loop diuretics work by inhibiting the reabsorption of sodium and chloride in the loop of Henle in the kidney, leading to increased diuresis. However, this mechanism of action can also lead to increased excretion of other electrolytes, such as magnesium.

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: A

Rationale: The described presentation is classic for acute angle-closure glaucoma. This condition is characterized by sudden-onset severe eye pain, headache, nausea, and vomiting. The red eye, steamy cornea (corneal edema), and mid-dilated non-reactive pupil are consistent with acute angle-closure glaucoma. The sudden increase in intraocular pressure leads to impaired aqueous humor outflow, causing these symptoms. Immediate intervention is required to prevent permanent vision loss in such cases. Central retinal artery occlusion would present with sudden painless vision loss. Optic neuritis typically presents with vision loss and pain with eye movements. Corneal ulcer presents with eye discomfort, foreign body sensation, and may have a history of corneal trauma or contact lens wear.

Correct Answer: D

Rationale: Public Health Nursing is a specialized field of nursing that focuses on promoting and protecting the health of populations and communities rather than individuals. One of the key principles of Public Health Nursing is the emphasis on health promotion and disease prevention strategies. This involves educating and empowering individuals, families, and communities to adopt healthy behaviors and lifestyles in order to prevent illness and improve overall well-being. Public Health Nurses work to address the root causes of health disparities and advocate for policies and programs that promote the health of entire populations. While providing care to sick individuals may be a component of Public Health Nursing, the primary focus is on preventing illness and promoting health at the community level.
