Answer:

The correct answer is C.

Explanation:

The respiratory center is divided into 3 main groups, the dorsal respiratory group and the ventral respiratory group, both located in the <u>medulla</u>, and the pontine respiratory group, located in the <u>pons</u>. This last one also divides into two areas: <em>the pneumotaxic and the apneustic center.</em>

During quiet, restful breathing, the dorsal group stimulates the diaphragm and the intercostal muscles for inspiration. Expiration then occurs depending on the elastic recoil of the lungs. When forced expiration is required, the ventral group activates.

Modern epidemiology involves history since finding the causes of chronic diseases requires looking back for <u>decades</u>.

In the past, infectious diseases, which were the leading cause of death, were the primary focus of epidemiological research. This was especially true after the advent of urbanization when populations began to concentrate in cities. Better hygiene, vaccination rates, and antibiotics were able to put an end to the epidemics.

Epidemiology gradually evolved into the study of the causes, the distribution, the risk factors, and the prevention of chronic diseases, but it also expanded to include the study of diseases with a mass occurrence at the population level, such as depression, and accidents. The medical community has slowly come around to the idea that diet plays a significant role in overall health, but they continue to give it less weight than it deserves.

A nurse caring for a client in diabetic ketoacidosis (DKA) , Which of the following is the priority intervention by the nurse qu
zvonat [6]

The priority intervention when treating a client with diabetic ketoacidosis (DKA) is the intravenous administration of fluids, electrolytes, and insulin.

<h3>Diabetic ketoacidosis (DKA).</h3>

A potentially fatal Diabetes Mellitus consequence is diabetic ketoacidosis. Common symptoms of DKA are:

  • Vomiting,
  • stomach discomfort,
  • gasping for air,
  • excessive urination,
  • weakness,
  • disorientation,
  • loss of consciousness,
  • "fruity" odor

Symptoms generally appear quickly. DKA may appear in people who have never had diabetes before as their first noticeable symptom.

DKA most frequently affects people with type 1 diabetes, although it can also happen to people with other forms of diabetes in specific situations like improper insulin administration.

A lack of insulin causes DKA, which causes the body to resort to burning fatty acids instead, leading to the production of acidic ketone bodies that lead to metabolic acidosis (an acid-base disorder).

When a client is in DKA, the top priority is to IV administer fluids (the excessive urination leads to dehydration), replace the electrolytes (DKA causes severe alteration in the normal concentrations of electrolytes; these need to be replaced for the correct amount to secure the normal functioning of many organs) and insulin (this reverses the DKA).

On the first postpartum day, a neonate diagnosed with an ABO incompatibility has a bilirubin level of 10 mg/dL (170 µmol/L). Aft
Ivanshal [37]

Answer:

"The baby will need an exchange transfusion with type A blood."

Explanation:

The mother would need to be enlightened about how ABO incompatibility works and the necessary solution. She said "The baby will need an exchange transfusion with type A blood." However ABO compatibility happens when the mother has type O blood group and the neonate is either A, B, or AB and unless the bilirubin concentration reaches dangerous levels such as (~20 mg/dL or 342 umol/L), there is no need for an exchange transfusion. If an exchange transfusion does become necessary, type O blood is used or treatment with phototherapy.
