Answer:

The correct answer is (D) Instrument's ability to identify noncases correctly.

Explanation:

A specificity of diagnostic instruments means that the instrument have the ability to identify those person correctly who is not having the disease.

There are very few results that are false positive in any highly specific diagnostic test. Therefore specificity used to show the negative results of patients that means it identifies the non-diseased persons correctly.

The sensitivity of the diagnostic instruments means it correctly identifies individuals having disease.  So in sensitivity, diseased persons who are positive for the disease are diagnosed correctly.

Therefore the correct answer is (D) Instrument's ability to identify noncases correctly.

A five-year-old presents to the emergency department with epiglottitis. what is the nurse's first priority?
fredd [130]

A five-year-old presents to the emergency department with epiglottitis

the nurse's first priority should be control of anxiety,facilitation of learning, Medications, and Hydration.

<h3>Epiglottis</h3>

The throat's epiglottis, a leaf-shaped flap, serves to keep food and liquids out of the windpipe and the lungs. When breathing, it remains open, allowing air to enter the larynx. It closes during swallowing to stop food from being inhaled into the lungs, forcing any liquids or food to travel down the esophagus and toward the stomach.

<h3>Interventions in Nursing</h3>

For a child with epiglottitis, the nursing interventions are:

  • control of anxiety:- The family should demonstrate personal activities that will help the youngster get rid of or lessen emotions of anxiety and stress that are coming from an unknown source.
  • facilitation of learning:- In addition to encouraging progress in the patient's capacity and openness to accept information, the nurse should support their ability to process and comprehend information.
  • Medications:- As directed, give antibiotics such as cefuroxime.
  • Hydration:- Since the child couldn't swallow, adjust the IV fluid as necessary.

Aminiotic fluid formation and clearance ? ​
stich3 [128]

Introduction :-)

The <em>amniotic fluid</em> is the protective liquid contained by the <em>amniotic sac</em> of a <em>gravid amniote</em>. This <em>fluid</em> serves as a cushion for the growing <em>fetus</em>, but also serves to facilitate the exchange of nutrients, water, and biochemical products between <em>mother</em> and <em>fetus</em>.

Importance :-)

  1. <em>It helps to protect the fetus from trauma to the maternal abdomen.</em>
  2. <em>It cushions the umbilical cord from compression between the fetus and uterus.</em>
  3. <em>It has antibacterial properties that provide some protection from infection.</em>
  4. <em>It serves as a reservoir of fluid and nutrients for the fetus.</em>

<em></em>

Formation :-)

<em>Amniotic fluid </em>is present from the formation of the <em>gestational sac.</em> <em>Amniotic fluid </em>is in the <em>amniotic sac.</em> It is generated from <em>maternal plasma</em>, and passes through the <em>fetal membranes</em> by <em>osmotic</em> and <em>hydrostatic forces</em>. When <em>fetal kidneys</em> begin to function around week 16, <em>fetal urine</em> also contributes to the <em>fluid.</em> In earlier times, it was believed that the <em>amniotic fluid</em> was composed entirely of <em>fetal urine</em>.

The <em>fluid</em> is absorbed through the <em>fetal tissue</em> and <em>skin</em>. After <em>22 to 25 week </em>of<em> pregnancy</em>, <em>fraternization</em> of an <em>embryo's skin</em> occurs. When this process completes around the <em>25th week</em>, the<em> fluid</em> is primarily absorbed by the <em>fetal gut</em> for the remainder of <em>gestation</em>.

<em>Contents :-)</em>

At first, <em>amniotic fluid</em> is mainly water with <em>electrolytes</em>, but by about the <em>12-14th week</em> the <em>liquid</em> also contains <em>proteins, carbohydrates, lipids and phospholipids, and urea</em>, all of which <em>aid</em> in the growth of the <em>fetus</em>.

Hope its helpful :-)

<h3>What are the effects of Oxybutynin  toxicity?</h3>
  • Oxybutynin toxicity (overdose) causes central nervous system excitation, which includes jitteriness, restlessness, hallucinations, and irritability.
  • Hypotension or hypertension, tachycardia, disorientation, a flushed or red face, and indications of respiratory depression are further symptoms of poisoning.
  • The drug's common adverse effect of sleepiness does not signify overdosage, though.
