Which of the following events occur at the start of diastolic production of first heart sounds S1

1 answer:

6 0

Answer: Ok Diastole commences with the closure of the aortic and pulmonary valves. Intraventricular pressure falls but there is very little increase in ventricular volume (isovolumetric relaxation). Once ventricular pressure falls below atrial pressure, the mitral and tricuspid valves open and ventricular filling begins.The first heart sound (S1) is produced by vibrations generated by closure of the mitral (M1) and tricuspid valves (T1). It corresponds to the end of diastole and beginning of ventricular systole and precedes the upstroke of carotid pulsation.

Hope this helps have a awesome day/night❤️✨

Going about her cleaning routine as usual, Jayla sprays an aerosol bleach cleanser in her bathroom and then leaves to let it air

SashulF [63]

Answer:

inhaled poison

Explanation:

Grimaldi was inside the bathroom when Jayla sprayed the aerosol bleach cleanser. The molecules of this cleanser spread quickly through the surroundings. Since the cat was inside the bathroom, it could have inhaled the bleach and the poison reached its lungs. This caused symptoms of wheezing, which is respiratory in nature, and shaking (seizures). Inhaling a poison leads to difficult in breathing among animals because it can cause the lungs to be inflamed.

The nurse suspects that an older adult patient has features of basal cell carcinoma appearing in form of a small dome-shaped lesion with a pearly surface on the face.

What is Basal cell carcinoma?

The most prevalent type of skin cancer that is not melanoma is basal cell carcinoma (BCC).

It is a tumour that causes localized damage and has a variety of clinical and histological characteristics.

When viewed at low power magnification, a basaloid epithelial tumour emerging from the epidermis is the primary characteristic of basal cell carcinoma.
Normally, the palisade-like basaloid epithelium forms a fissure from the surrounding tumour stroma.

The nuclei grow congested in the centre, with scattered mitotic figures and visible necrotic bodies.

The presence of a mucinous stroma serves as a helpful distinguishing factor from other basaloid cutaneous tumours. Additionally, some tumours may exhibit foci of regression, which are regions of eosinophilic stroma devoid of basaloid nests.

Hence, the answer is a small dome-shaped lesion with a pearly surface on the face.
