Correct Answer: B

Rationale: The correct answer is B (AB). AB blood type is the rarest because it is a result of inheriting both A and B alleles, making it less common in the population. AB individuals can only receive blood from other AB individuals due to their unique antigens. Blood types A, B, and O are more common in the population, with O being the most common as it is the universal donor. Blood type A and B are more common than AB since they only require one allele for their respective antigens. Thus, the rarity of AB blood type is due to the inheritance of both A and B alleles, making it the least common among the choices provided.

Correct Answer: D

Rationale: The correct answer is D: Pinkeye. Acute bacterial conjunctivitis is commonly referred to as "pinkeye" due to the characteristic pink or red appearance of the eye. This condition is caused by a bacterial infection of the conjunctiva, the thin membrane that covers the white part of the eye and inner eyelids. The term "glaucoma" (A) refers to a different eye condition characterized by increased intraocular pressure, while "color blindness" (B) is a genetic condition affecting color vision. "Astigmatism" (C) is a refractive error related to the shape of the cornea or lens, not an infection of the eye. Therefore, the correct answer is D as it accurately identifies the common name for acute bacterial conjunctivitis.

Correct Answer: C

Rationale: The correct answer is C because washing feet in hot water can lead to burns or skin damage for those with diabetes. A: Proper footwear is essential for preventing foot injuries. B: Trimming toenails straight across helps prevent ingrown nails. D: Wearing shoes on hot surfaces prevents burns or blisters. Overall, C is incorrect due to the potential harm it can cause to diabetic feet.

Correct Answer: C

Rationale: The correct initial treatment for stage IV ovarian cancer is major surgery (Choice C). This is because at this advanced stage, surgery is typically performed to debulk the tumor and remove as much cancerous tissue as possible, followed by chemotherapy to target any remaining cancer cells. Radiation therapy (Choice A) is not typically the initial treatment for ovarian cancer. Chemotherapy (Choice B) is often used in combination with surgery, but surgery is usually the first line of treatment for stage IV disease. Choosing no treatment (Choice D) would be detrimental as the cancer is advanced and requires immediate intervention.

Correct Answer: A

Rationale: The correct answer is A because shampooing the hair thoroughly helps remove oil and dirt, which can interfere with the CT scan results. By having clean hair, the scan can produce clearer images. Choice B is incorrect because some preparation is needed for a CT scan, especially regarding cleanliness. Choice C is incorrect as giving a cleansing enema and fluids until 8 AM is not necessary for a CT scan of the head. Choice D is incorrect as shaving the scalp and attaching electrodes are not part of routine preparation for a CT scan.
