Three-year-old C.E. is admitted to the emergency department fast-track clinic. Her mother tells the nurse that C.E. has had a low-grade fever for 2 days and is complaining frequently of ear pain and a sore throat. C.E.'s mother also notes that C.E. has been coughing and is a little hoarse. C.E.'s mother states that C.E.'s appetite has been "off," but she has been drinking and using the bathroom as usual. As you get C.E. settled in the exam room, you suspect C.E. may have otitis media (OM).

You continue to obtain a history from C.E.'s mother and learn C.E. has had "ear problems" and throat infections since she was a baby. She is in daycare each weekday, the father smokes outside of the house, and there is a family history of seasonal allergies. C.E. is allergic to penicillin. Her weight is 14 kg14 \mathrm{~kg} (31 lbs).

The primary care provider (PCP) diagnoses C.E. with bilateral AOM and strep pharyngitis. C.E. is given a prescription for Augmentin 600mg600 \mathrm{mg} twice daily PO×7P O \times 7 days and her mother is instructed to give acetaminophen 240mg240 \mathrm{mg} every 4 hours as needed for pain. She is to be discharged to home with instructions to follow up with the ear, nose, and throat (ENT) specialist.

C.E.s mother is given a new prescription for azithromycin (Zithromax) PO 160mg/160 \mathrm{mg} / day ×5\times 5 days. Azithromycin is dispensed as 200mg/5 mL200 \mathrm{mg} / 5 \mathrm{~mL}.

You are providing C.E.'s mother with information on medication administration. You use the Teach-Back technique to assess C.E.'s mother's learning. Which statements by C.E.'s mother indicate the need for further teaching? Select all that apply, and explain your answers.

a. "This medicine can be given with or without food." b. "I don't have to finish the medication if she feels better after a few days." c. "I will place the correct amount of antibiotic in the ear canal once a day." d. "If C. refuses to take her medication, I will tell her it tastes like the candy we get at the movies." e. "I will monitor for vomiting, diarrhea, or stomachaches because this might be a side effect of the medication."

The general solution of the given homogeneous differential equation is:

y(t)=c1y1(t)+c2y2(t),\begin{aligned} y(t)=c_1y_1(t)+c_2y_2(t), \end{aligned}

where c1c_1 and c2c_2 are arbitrary constants.
