Allergy: NKDA ROS: General: Grandma reports fever up to 102.2 last night, fever reducer last given 2 hours ago.   Does watch TV when fever down but very irritable. Several kids in his class at school with URI. HEENT: nose with slight clear discharge, sometimes complains of a headache. Lungs: Started out as a dry cough but has progressed to a rattly cough and all day long. Like he needs to cough something up. One time grandma noted some streaks of blood when he spit out sputum. Abdomen: child reports his “tummy hurts,” no diarrhea or constipation, last BM yesterday, no vomiting, does have decrease appetite Musculoskeletal: plays well normally   Assessment: HR: normal RR: 55 O2 sat: 94%ra Wt: 30lb Temp: 100.6   General: no acute distress but does look sick. HEENT: mucus membranes moist, scant amount of discharge from bilateral nares. Heart: rate regular with no murmur Lungs: diminished breath sounds and crackles in left middle and lower lobe. No retractions or nasal flaring. Abdomen: round, bowel sounds active, soft, nontender Skin: warm, dry, with no rashes What are the differential Diagnosis?   Diagnostic Tests: Flu- negative   What is your diagnosis? What is the plan of care/treatment?  If ordering a medication, what is the recommended dose?  

White light consisting of wavelengths ranging from 400nm to 700 nm fall incident upon a diffraction grating having 600 lines/mm. The first order spectrum extends over a range of angles on a screen. Next, the grating is removed and replaced with one having 900 lines/mm. Which of the following statements are correct about the range of angles comprising the first order spectrum?

A 2.0 cm tall object is 20 cm in front of a converging lens that has a 60 cm focal length. What is the image size and is it upright or inverted?

Case study:  Moira Moira is a 54-year-old female with a two-day history of a pulsating/throbbing headache which is worse with movement and physical activity.  She describes photophobia and phonophobia.  She is nauseated but has not vomited.  Moira describes the pain as 6-7/10, with 10 being the worst pain imaginable.  The pain began while at work 2 days ago.  It started with her seeing what she describes as halos around lights.  Moira has a history of migraine headaches.  She has been given naproxen sodium 500 mg. tablet, to take at onset of headache and then every 12 hours as needed for pain.  She has taken it as prescribed, but the headache has not resolved.  Moira is very frustrated.  She has these types of headaches approximately 5 days out of the month and often misses 1-2 days of work each month due to these migraines.  Moira reports no change in the frequency or intensity of these headaches, but no longer feels the current treatment plan is effective.  She has not been to work since this headache began 2 days ago.  Based on what you know, what is your diagnosis? Are there any diagnostic tests you would order? What is your treatment plan for Moira going forward?  Include any changes you would make to the current treatment plan. Please include patient teaching

Coherent light with wavelength 450 nm is incident upon a pair of slits. The interference pattern produced on a screen 2.0 m from the slits is measured to have a separation between two adjacent bright fringes of 1.8 mm. Next, a laser with an unknown wavelength shines upon these same pair of slits and screen. The interference pattern shows the distance between adjacent bright fringes is 0.5mm. What is the wavelength of this mystery laser, in nm?
