How does eating influence high density lipoproteins (HDL) in the body?

Answer: The element with the greatest influence on cholesterol levels is the fat content of food. Not only the amount of cholesterol, but also the type of fat.

Explanation:

Cholesterol is a type of fat found in the body, which is used to make hormones and vitamin D. The liver makes cholesterol to handle these tasks, but cholesterol can also be incorporated into the body through foods such as meat, dairy, and poultry. If you consume a lot of these, the cholesterol levels could become too high.

There are two types of cholesterol:

  • High-density lipoprotein (HDL) or “good cholesterol”. It transports     the excess of cholesterol to be expelled so<u> it wont end up in the arteries.  </u>
  • Low-density lipoprotein (LDL) or “bad cholesterol”.<u> It transports cholesterol to the arteries, where it may collect in artery walls.</u> This could  lead to a buildup of plaque known as atherosclerosis which can increase the risk of blood clots and if one of them breaks away and blocks an artery, it could cause a stroke or heart attack.

If there is a predominance of saturated fatty acids in the fat of the diet, a rise in serum cholesterol and LDL-cholesterol is caused.  To lower the bad cholesterol, you should limit foods such as milk fats, fatty meats or sausage and include more fibre in your diet.  On the other hand, <u>polyunsaturated fatty acids - for example, those present in seed oils or fish - produce their reduction. Monounsaturated fatty acids, such as those provided by olive oil, act like polyunsaturated ones and, in addition, tend to raise HDL-cholesterol, so their use entails a greater benefit.</u>

Which muscles assist in inhalation when running up the stairs? A) sternocleidomastoid, pectoralis major, scalenes B) sternocleid
Ulleksa [173]

Answer:

Sternocleidomastoid, pectoralis minor, scalenes

Explanation:

During normal inhalation, contraction of the diaphragm and the contraction of external intercostals expands the chest cavity. The increased volume of the thoracic cavity results in reduced alveolar pressure than the atmospheric pressure to facilitate the flow of air into the lungs in response to the pressure gradient.

During deep inhalation as it occurs when running up the stairs, the accessory muscles of inhalation also participate to increase the volume of the chest cavity. The contraction of scalene and sternocleidomastoid muscles increase the volume of the chest cavity further to create a greater drop in alveolar pressure.

During forceful inhalation, the sternocleidomastoid muscles serve to elevate the sternum, the scalene muscles serve to elevate the first two ribs while the pectoralis minor elevate the third through fifth ribs.

A nurse is gathering subjective and objective data during the initial assessment of a client. Which statement best reflects how
Amanda [17]

Answer:

<em><u>The answer is</u></em>: <u>The objective data are those that will help the nurse in subsequent consultations, since these are observable and measurable.</u>

<u />

Explanation:

<u>The assessment is the first phase</u>, and can be described as the organized and systematic process of collecting data from different types and sources, to analyze the health status of the person.

<u>During the assessment</u>, the nurse gathers four types of data: subjective, objective, historical and current. The mixture of all these types is normally given in a complete and accurate database.

Subjective data could be described as the individual's vision of a situation or series of events. This information cannot be determined by the nurse regardless of the relationship or communication with the individual.

Objective data are observable and measurable. This information is usually obtained through the senses, sight, smell, hearing and touch, during the physical examination of the patient.

<em><u>The answer is</u></em>: <u>The objective data are those that will help the nurse in subsequent consultations, since these are observable and measurable.</u>
