In many reptiles, sex determination is dependent not on sex chromosomes but rather environmental conditions such as temperature. Species that use temperature are said to have temperature-dependent sex determination (TSD). One known mechanism for TSD in some species is the temperature-dependent activity of an enzyme, aromatase, that acts to convert androgens (hormones that promote male development) to estrogens (hormones that promote female development). You have begun to study two species of lizards that seem to use TSD. You collect eggs from both species and rear them at various temperatures with and without applied fadrozole, a chemical that specifically inhibits the activity of aromatase. Your results are as follows. Based on these results, what can you conclude about sex determination in species A and species B?

M.K. is an 80-year-old female who has been taking over-the-counter (OTC) famotidine for indigestion for 2 weeks without significant relief. She decided to contact her healthcare provider because the symptoms were worsening. She is admitted to the hospital with increasing abdominal pain for the last 5 days. Her admission diagnosis is GERD, and she is scheduled for an esophagogastroduodenoscopy (EGD) to rule out peptic ulcer disease. She is to begin therapy with the oral proton-pump inhibitor omeprazole. The RN documents these findings as part of her admission assessment.Which of the following findings require follow-up by the nurse? (Select all that apply)
