Sticks commonly used for nail care are called

Correct Answer: D

Rationale: The correct answer is D: Orangewood sticks. Orangewood sticks are commonly used for nail care due to their sturdy yet gentle properties. They are soft enough to push back cuticles and clean under nails without causing damage. Rosewood, Greasewood, and Sandalwood sticks are not typically used for nail care purposes. Rosewood is more commonly used in furniture making, Greasewood is a type of shrub, and Sandalwood is known for its aromatic properties, not for nail care.

Correct Answer: C

Rationale: The correct answer is C: Heartburn. When the sphincter muscle joining the esophagus is weakened, it allows stomach acid to flow back into the esophagus, causing a burning sensation in the chest known as heartburn. This occurs due to the reflux of stomach contents into the esophagus. Gastroesophageal discomfort (choice A) is vague and not specific to the weakened sphincter muscle. Ulcers (choice B) are typically caused by bacteria or excessive use of NSAIDs, not by a weakened sphincter. Malabsorption (choice D) is related to the inability to absorb nutrients properly in the intestines, not the esophagus. Therefore, the correct answer is C because it directly correlates with the consequence of a weakened sphincter muscle in the esophagus.

Correct Answer: D

Rationale: The correct answer is D: Trichomoniasis. This STI is caused by a parasite called Trichomonas vaginalis, not a bacteria like gonorrhea (A) or chlamydia (C). Symptoms include itching and swollen genitals, not vaginal bleeding like in cases of vaginitis (B). Trichomoniasis is commonly associated with these specific symptoms, making it the most appropriate choice.

Correct Answer: C

Rationale: The correct answer is C: Taking diuretics to reduce fluid volume. Diuretics help lower blood pressure by promoting the removal of excess fluid and sodium from the body, reducing the volume of blood flowing through the blood vessels. This decreases the pressure on the vessel walls, thereby reducing hypertension. A: Reducing the amount of exercise is incorrect because exercise is actually beneficial for managing hypertension by improving cardiovascular health and lowering blood pressure. B: Increasing fat in the diet is incorrect as high-fat diets can lead to obesity and other risk factors for hypertension. D: Increasing weight is incorrect as obesity is a known risk factor for hypertension, and weight gain can exacerbate the condition.

Correct Answer: B

Rationale: The correct answer is B: Bursae. Bursae are small sacs filled with synovial fluid near joints that help reduce friction between bones, tendons, and muscles. Tendonitis (A) is inflammation of a tendon, not fluid-filled sacs. Sepsis (C) is a severe infection in the bloodstream, unrelated to joint structures. Phlebitis (D) is inflammation of a vein, not associated with joint fluid sacs. Therefore, Bursae is the only choice that accurately describes the tiny sacs of fluid near joints.
