C.

Answers

Answer 1

Answer:

Alveoli are found on the end of bronchioles which is option C.

Alveoli are small air sacs found within the lungs that resemble a cluster of grapes. These are also known as pulmonary alveoli. They primarily stimulate gas exchange.

What is the function of alveoli?

The alveoli are the final stage of the respiratory system, which begins when we inhale air via our mouth or nose.

The oxygen-rich air passes via the trachea and into one of the two lungs through the right or left bronchus.

Carbon dioxide molecules, produced as a byproduct of respiration, are diffused back to the alveolus and ejected from the body via the nose or mouth.

Because the diaphragmcontracts, creating negative pressure within the chest, alveoli expand during inhaling. Because the diaphragm relaxes during exhaling, the alveoli rebound (spring back).

Thus, we can conclude that option C is correct.

4 hrs pp, pt reports severe vulvar pain and severe rectal pressure. Most likely symptoms for?

Answers

Answer:

Severe vulvar pain and severe rectal pressure reported 4 hours after childbirth are most likely symptoms of perineal trauma or injury. During childbirth, the perineum (the area between the vagina and rectum) can stretch or tear, leading to discomfort and pain. Here are some possible causes and considerations:

1. Perineal tears: The pressure and stretching during childbirth can cause tears in the perineal tissue, ranging from mild to severe. These tears can result in pain and discomfort in the vulvar area and may also lead to rectal pressure.

2. Episiotomy: In some cases, a healthcare provider may perform an episiotomy, which is a surgical incision made in the perineum to enlarge the vaginal opening during delivery. This procedure can also cause pain and rectal pressure as the area heals.

3. Hemorrhoids: Hemorrhoids, swollen blood vessels in the rectal area, can be aggravated during childbirth due to straining. This can lead to rectal pressure and discomfort.

4. Engorged tissues: After childbirth, the tissues in the vulvar area can become engorged and swollen, causing pain and discomfort.

It is important for the patient to seek medical attention to evaluate the extent of the perineal trauma and determine the appropriate treatment. Treatment options may include pain management, sitz baths, topical creams, and, in severe cases, suturing or surgery.

Explanation:

In summary, severe vulvar pain and rectal pressure reported 4 hours after childbirth are likely symptoms of perineal trauma or injury. Perineal tears, episiotomy, hemorrhoids, and engorged tissues are possible causes. Seeking medical evaluation and appropriate treatment is important for managing the symptoms and promoting healing.
