A pregnant woman presents with severe lower abdominal pain and vaginal bleeding. On examination, cervical motion tenderness and unilateral adnexal tenderness are noted, along with an adnexal mass on the affected side. Which of the following conditions is the most likely cause of these symptoms?

Correct Answer: A

Rationale: The clinical presentation of severe lower abdominal pain and vaginal bleeding in a pregnant woman, along with cervical motion tenderness, unilateral adnexal tenderness, and an adnexal mass on the affected side, is highly concerning for an ectopic pregnancy. Ectopic pregnancy occurs when a fertilized egg implants outside the uterus, most commonly in the fallopian tube. The presence of an adnexal mass and tenderness on one side is indicative of potential tubal involvement and can mimic symptoms of pelvic inflammatory disease. Prompt evaluation and management are crucial in ectopic pregnancy to prevent life-threatening complications associated with rupture of the fallopian tube.

Correct Answer: A

Rationale: The patient's presentation of gradual-onset memory loss, confusion, difficulty with complex tasks, disorientation, and functional decline are all classic features of Alzheimer's disease. Alzheimer's disease is a progressive neurodegenerative disorder characterized by the accumulation of abnormal protein deposits in the brain, leading to widespread neuronal damage and cognitive decline. As the disease progresses, patients typically experience worsening memory loss, cognitive impairment, and deficits in activities of daily living, ultimately requiring full-time care and assistance. Other neurodegenerative diseases such as Parkinson's disease, Huntington's disease, and frontotemporal dementia may present with cognitive impairment and behavioral changes, but the specific constellation of symptoms described in the case is most indicative of Alzheimer's disease.

Correct Answer: A

Rationale: IgA is the primary immunoglobulin class involved in providing passive immunity to newborn infants through breast milk. IgA antibodies are highly concentrated in colostrum and breast milk, offering important protection to newborns against infections. IgG antibodies can also be passed from the mother to the fetus through the placenta, providing passive immunity during pregnancy, but IgA is the main immunoglobulin class transferred through breast milk for protecting the infant's gastrointestinal and respiratory tracts. IgE is mainly involved in allergies and hypersensitivity reactions, while IgM is an early responder in the immune response to infections.

Correct Answer: B

Rationale: The best position for a patient to assume during an admission procedure, particularly for respiratory assessment, is the semi-fowler position at least 30 degrees. In the semi-fowler position, the patient's head and upper body are elevated to a 30-degree angle. This position helps improve lung expansion and oxygenation by reducing pressure on the diaphragm and enhancing chest expansion. It also facilitates breathing and allows for better assessment of respiratory status. Additionally, the semi-fowler position helps prevent aspiration and promotes comfort and relaxation for the patient during the admission procedure.

Correct Answer: B

Rationale: The most likely diagnosis in this scenario is epididymitis. Epididymitis is an inflammation of the epididymis, a coiled tube at the back of the testicle that stores and carries sperm. Common symptoms include scrotal pain, swelling, erythema (redness), and a tender, fluctuant mass in the scrotum due to an abscess. Risk factors for epididymitis include urinary tract infections, sexually transmitted infections (such as gonorrhea or chlamydia), and recent urological procedures. It is important to differentiate epididymitis from testicular torsion, which would present with sudden, severe testicular pain, absent cremasteric reflex, and a high-riding testicle. Testicular cancer typically presents as a painless mass or swelling in the scrotum, and hydrocele presents as painless scrotal swelling due to a collection of fluid

Correct Answer: B

Rationale: Convenience sampling involves selecting participants who are readily available or easy to access. In this scenario, choosing to interview nurses who happen to be in the conference room where the activity is scheduled falls under convenience sampling as they are easily accessible at that moment. While convenience sampling may be convenient, it may introduce bias and may not represent the entire population accurately.

Correct Answer: D

Rationale: #NAME?

Correct Answer: A

Rationale: Respondent superior is a legal doctrine that holds an employer (such as a nurse) responsible for the actions of their employees (such as a barangay health worker) performed within the scope of their employment. In the scenario provided, the nurse delegated tasks to the barangay health worker, making the health worker an agent of the nurse. By closely monitoring the delegated work, the nurse is fulfilling her legal responsibility under the principle of respondent superior to ensure that the health worker performs their duties properly and in accordance with professional standards.

Correct Answer: D

Rationale: Hurthle cell carcinoma is a subtype of thyroid cancer that arises from the follicular cells in the thyroid gland. Patients with Hurthle cell carcinoma may present with a painful thyroid nodule, which can be associated with signs of hypothyroidism due to the disruption of thyroid hormone production by the tumor. Fine-needle aspiration biopsy revealing Hurthle cells with nuclear features suggestive of malignancy is a characteristic finding in this type of carcinoma.
