What isotonic electrolyte solutions are COMMONLY used as fluid replacement in hypovolemic shock? I. Dextrose 5 percent in water II. 0.9 percent sodium chloride III. Lactated Ringer's solution IV. Dextrose 10 percent in water

Correct Answer: B

Rationale: In hypovolemic shock, isotonic electrolyte solutions are commonly used for fluid replacement to restore the circulating blood volume. The commonly used isotonic electrolyte solutions for this purpose are 0.9% sodium chloride (normal saline) and lactated Ringer's solution.

Correct Answer: C

Rationale: Ménière's disease is characterized by the triad of symptoms including progressive sensorineural hearing loss, tinnitus, and vertigo. The audiometric testing in Ménière's disease often shows a "carrot-shaped" configuration, which refers to low-frequency hearing loss initially and eventually spreading to involve higher frequencies. This distinctive pattern of hearing loss helps differentiate Ménière's disease from other causes like Presbycusis (age-related hearing loss) or Noise-induced hearing loss. Acoustic neuroma can present with unilateral sensorineural hearing loss but typically does not exhibit the specific "carrot-shaped" configuration seen in Ménière's disease.

Correct Answer: C

Rationale: In this scenario, the action that violates a psychiatric patient's rights is option C, where staff members confiscated written letters done by patients addressed to the local newspaper. Patients have the right to communicate freely and express their thoughts and feelings through various means, such as letter-writing. Confiscating these letters is a violation of their rights to free expression and communication. It is essential to respect and uphold the rights of psychiatric patients, including their right to communicate with others.

Correct Answer: A

Rationale: The best thing to do next is to turn off the fan immediately. The fact that the electric fan is stopping every now and then and sparking at intervals indicates a potential electrical issue or malfunction. This situation poses a safety hazard as it increases the risk of an electrical fire or damage to the fan. Turning off the fan immediately will help prevent any further damage or potential danger. After turning off the fan, it would be advisable to call for maintenance to inspect and repair the fan to ensure it is safe to use again.

Correct Answer: A

Rationale: The clinical manifestations of Aster suggest acromegaly, a condition characterized by the excessive growth of hands and feet due to a tumor in the pituitary gland leading to overproduction of growth hormone. Cyanosis is a bluish discoloration of the skin caused by poor oxygenation, which is not typically associated with acromegaly. The other options do not match the unique clinical manifestation described for Aster. Anemia, weight loss, moon facies, and edema are more commonly associated with other conditions like Cushing's syndrome, anemia, or heart failure.

Correct Answer: C

Rationale: A profession is characterized by having a body of knowledge, a code of ethics, and engaging in research. However, being a member of a professional organization is not a defining characteristic of a profession. While many professionals may choose to join professional organizations for networking, support, and career advancement reasons, membership in such organizations is not universally required or exclusive to being considered a professional in a particular field. Hence, the presence or absence of professional organization membership does not determine the professional status of an individual.

Correct Answer: B

Rationale: In a pregnant woman presenting with severe abdominal pain and vaginal bleeding at 8 weeks gestation with a closed cervix, the most likely cause of these symptoms is a threatened abortion. A threatened abortion is a common complication of early pregnancy characterized by vaginal bleeding and lower abdominal pain without cervical dilation. The cervix remains closed, indicating that the pregnancy is still intact but at risk of potential miscarriage. Placenta previa typically presents with painless vaginal bleeding in the second or third trimester, whereas ectopic pregnancy usually presents with abdominal pain and vaginal bleeding in the setting of a closed cervix but is less likely at 8 weeks gestation. Gestational trophoblastic disease is a rare cause of vaginal bleeding in pregnancy and typically presents in the first trimester with signs of hyperemesis gravidarum, uterine enlargement, and elevated β-hCG levels.

Correct Answer: C

Rationale: The presentation described is consistent with fungal keratitis. Fungal keratitis typically presents with a yellowish-white spot on the cornea, surrounded by a ring of inflammation. The filamentous opacities seen on slit-lamp examination are characteristic of fungal hyphae extending from the corneal lesion. This condition is often associated with risk factors such as trauma with vegetable matter, contact lens wear, or topical corticosteroid use. Prompt diagnosis and treatment with antifungal medications are essential to prevent complications and preserve vision.

Correct Answer: B

Rationale: The term "collaborative" best fits the situation where a member of the Research Committee wishes to conduct a study involving an interdisciplinary team of colleagues. Collaboration refers to individuals, in this case, researchers or professionals from different disciplines coming together, sharing their expertise, and working collectively towards a common goal or project. In an interdisciplinary study, involving a collaborative approach enhances the diversity of perspectives, skills, and knowledge brought to the research, leading to more comprehensive and well-rounded outcomes. This type of study fosters cooperation, communication, and synergy among team members, thereby promoting innovation and understanding across different areas of expertise.
