Correct Answer: A

Rationale: The correct answer is high HDL cholesterol. High HDL cholesterol levels are associated with a decreased risk of cardiovascular disease because HDL helps remove LDL cholesterol from the arteries, reducing plaque buildup. Low HDL cholesterol (choice B) is actually associated with an increased risk of cardiovascular disease. Low total cholesterol (choice C) or low triglycerides (choice D) are not indicators of a decreased risk of cardiovascular disease; in fact, extremely low total cholesterol levels may indicate other health issues.

Correct Answer: B

Rationale: The correct answer is B: Eclampsia. Eclampsia is a disorder of pregnancy characterized by hypertension, proteinuria, and edema. This condition can cause seizures and/or coma but does not typically present with vaginal bleeding. Choices A, C, and D are abnormal conditions that can cause bleeding, particularly in the third trimester. Placenta previa (choice A) is a condition where the placenta partially or completely covers the cervix, leading to vaginal bleeding. Abruptio placentae (choice C) is the premature separation of the placenta from the uterine wall, causing vaginal bleeding. Uterine rupture (choice D) is a serious obstetrical emergency where the uterus tears during pregnancy or childbirth, resulting in severe bleeding.

Correct Answer: C

Rationale: Genital herpes can be transmitted through oral, genital, and anal sex. It's crucial to understand that the infection can be spread through intercourse even when symptoms are not present. Option A is incorrect because genital herpes is not transmitted through toilet seats. Option B is correct as oral sex can transmit the virus. Option D is incorrect as drinking fluids after sex does not prevent the transmission of genital herpes.

Correct Answer: D

Rationale: The correct answer is Morton's neuroma. Morton's neuroma is a small mass or tumor in a digital nerve of the foot, causing symptoms such as pain and difficulty walking. Hallux valgus is commonly known as a bunion and involves the deviation of the big toe towards the other toes. Hammertoe is a condition where one or more toes are bent in a claw-like position. Plantar fasciitis is characterized by pain and inflammation in the arch of the foot, not typically associated with a mass causing difficulty walking.

Correct Answer: B

Rationale: The correct answer is 'Toddlers.' Toddlers are at the highest risk of unintentional poisoning due to their natural curiosity, explorative behavior, and lack of awareness of potential dangers. Infants are typically closely monitored, teens are more aware of risks, and adults generally have better judgment and understanding of hazardous substances, making them less susceptible to unintentional poisoning. Therefore, toddlers, being inquisitive and unaware of risks, are the most vulnerable group in terms of unintentional poisoning incidents.
