Correct Answer: A

Rationale: Lactose intolerance commonly presents with frothy stools and diarrhea due to the inability to digest lactose. Other symptoms include abdominal distension, crampy abdominal pain, and excessive flatus. Foul-smelling ribbon stools are indicative of Hirschsprung's disease, not lactose intolerance. Profuse, watery diarrhea and vomiting are more characteristic of celiac disease. Diffuse abdominal pain unrelated to meals or activity is a typical symptom of irritable bowel syndrome, not lactose intolerance.

Correct Answer: A

Rationale: The patient is exhibiting classic signs of diabetes, such as polydipsia (feeling very thirsty), polyuria (large amount of water intake and urinary frequency), and xerostomia (dryness of the mouth). These symptoms are indicative of high blood glucose levels, which are characteristic of diabetes. Other common signs of diabetes include poor vision, unexplained weight loss, peripheral neuropathy (tingling in the feet and hands), and fatigue. Angina is chest pain due to reduced blood flow to the heart, not associated with the symptoms described in the patient. Hypertension is high blood pressure, which typically does not present with these specific symptoms related to diabetes. Hypotension is low blood pressure and is not consistent with the signs and symptoms presented by the patient, pointing more towards diabetes as the likely diagnosis.

Correct Answer: A

Rationale: Rapid bronchospasms are a symptom of an early-phase reaction in an asthmatic patient. During the early phase, bronchospasms occur due to immediate hypersensitivity reactions. Inflammatory epithelial lesions, increased secretions, and increased mucosal edema are typically seen in late-phase reactions as part of the inflammatory response that occurs later. Therefore, rapid bronchospasms are most indicative of an early-phase reaction.

Correct Answer: C

Rationale: To determine the drops per minute, we use the formula Drops Per Minute = (Milliliters x Drop Factor) / Time in Minutes. In this case, Drops Per Minute = (2000mL x 15 drops/mL) / (36 hours x 60 minutes/hour) = 30000 / 2160 = 13.89 (approximately 14). Therefore, the correct answer is 14 drops per minute. Choice A (8), Choice B (10), and Choice D (18) are incorrect as they do not correctly calculate the drops per minute based on the given information.

Correct Answer: B

Rationale: Chlamydial infections are one of the most common causes of salpingitis or pelvic inflammatory disease. Chlamydia can ascend from the vagina or cervix to the reproductive organs, leading to inflammation and infection. Trichomoniasis, caused by a parasite, typically presents with different symptoms than pelvic inflammatory disease and is not the primary cause. Staphylococcus and Streptococcus are bacteria that can cause other types of infections but are not the primary culprits in most cases of pelvic inflammatory disease.
