The nurse has administered a client's first scheduled dose of amoxicillin. what subsequent client report should prompt the nurse
Alexeev081 [22]

Amoxicillin is a broad-spectrum antibiotic widely used for certain bacterial infections in the ear, nose, throat, genitourinary tract, skin, lower respiratory tract, and its also used to treat gonnorhea. Amoxicillin is a fairly strong drug, and it can elicit an allergy to patients even to those who had used the drug before and did not experienced any untoward problems. If the patient had symptoms such as difficulty in breathing, itching, and untoward swelling or lump in the throat when receiving treatment with penicillins like amoxicillin, sulbactam, ampicillin, methicillin, or penicillin G, the nurse should discontinue giving amoxicillin and report to the doctor right away.

The presence of light waves activates the suprachiasmatic nucleus and the secretion of _____, promoting the wake cycle, while th
Brut [27]

The activation of the suprachiasmatic nucleus is stimulated by the presence of the light waves. This activation leads to the release of the hormone serotonin. Serotonin promotes the wake cycle of the person along with his internal clock. However, when the light is absent, then the pineal gland, which is present at the top of the middle of the brain, secretes the hormone melatonin. The melatonin regulates the sleep cycle of the person.

Hence, the blanks can be filled with 'serotonin and melatonin' respectively.

Which of the following best describes the Lianas vine?
raketka [301]

The answer is; C

It is a woody plant with a flexible stem that can grow extremely long. Its stem cannot stand vertically on its own hence uses other trees for support and climbs up the canopy for good sunlight. They are common plants in rainforests and play a significant role in the ecosystems. They provide support for weaker trees from strong winds and provide bridges for arboreal animals such as monkeys.

Bob, a nutritionist who works for the university medical center, has been asked to prepare special diets for two patients, susan
abruzzese [7]

Answer and Explanation:

Possibly, you forgot to attach the table with the contents of each food. Therefore, I calculated the task with similar values.

1. <em>Assume you have Food A, B, and C. Each has certain amount of Calcium, Iron, and Vit C. </em>

<em>             </em>Let's designate: Calcium <em>→ X oz , Iron → Y oz, vit C → Z oz</em>

2. <em>Assume you have following amount of</em><em> Calcium</em><em> in each food: </em>

  • Food A = 30 mg/oz
  • Food B = 25 mg/oz
  • Food C = 20 mg/oz

3. <em>Assume you have following amount of</em><em> Iron </em><em>in each food: </em>

  • Food A = 1 mg/oz
  • Food B = 1 mg/oz
  • Food C = 2 mg/oz

4. <em>Assume you have following amount of</em><em> vit C </em><em>in each food: </em>

  • Food A = 2 mg/oz
  • Food B = 5 mg/oz
  • Food C = 4 mg/oz

<u>Calculations:</u>

→ You have 3 different food and each has Calcium in it. You need exactly 320mg of Calcium per day. Therefore, each food would comprise certain proportion of daily Calcium intake. We can come up with equation: 30X+25Y+20Z = 390 mg

  • Similarly, for iron and vitamin C, the next equations could be used:

        X+Y+2Z=17 - Iron

        2X+5Y+4Z=42 - Vit C

→ Now you have a system of equations:

30X+25Y+20Z = 390 <em>(1) </em>

X+Y+2Z=17 <em>(2)</em>

2X+5Y+4Z=42 <em>(3)</em>

→ Look for similarities! <em>(1) and (3) </em>seem to be similar. We can multiply the <em>(3) </em>by -5 to obtain: -10X-25Y-20Z=-210. We add the <em>(1)</em> and modified <em>(3)</em> equations.

30X+25Y+20Z = 390

-10X-25Y-20Z=-210

__________________

20X+0+0=180

20X=180

<em><u>→ X=9 (oz of Calcium)</u></em>

<em><u></u></em>

→ Now, we can put<em> x=9 </em>into equations above to ease our job:

270+25Y+20Z=390 → 25Y+20Z=390-270=120

9+Y+Z=17 → Y+2Z=17-9=8

18+5Y+4Z=42 → 5Y+4Z=42-18=24

→ Similarly, we can use Eq-s <em>(2) and (3). </em>We can multiply the <em>(2) </em>by -5 to obtain: -5Y-10Z=-40. We add the <em>(3)</em> and modified <em>(2)</em> equations.

-5Y-10Z=-40

5Y+4Z=24

__________________

-6Z=-24

Z=4

<em><u>→ Z=4 (oz of vit C)</u></em>

<em><u></u></em>

→ Now, we can take X+Y+Z=17 <em>(2) </em>and just put in known values(<em>X=9 and Z=4</em>) to obtain Y:

9+Y+4=17

<u>→ Y=17-9-4=4 (oz of Iron)</u>

<u></u>

That's all! So, if you have table values, you can just re-write the equations and doing it stepwise, as it is shown here, you can manage to calculate every value you need :)
