Answer:

Calcium channel blocker which is used to treat hypertension due to its effect of vasodilator is B) Nifedipine

Explanation:

Calcium channel blocker is a drug whose usage is that the they prevent calcium from entering in to the muscle cells of heart and arteries.

Nifedipine is one of many types of channel blocker, it is a medication which is used to when a person is experiencing chest pain and hypertension. This medication keeps the blood vessel relaxing , so that the blood can easily flow. Nifedipine helps in relaxing smooth muscle by causing vasolidation which is a phenomenon that happens when there is a reduction in the contraction of artery and expansion of diameter of arteries.

Recommended daily allowance (RDA) is the nutritional requirement and uptake of the food. One has to eat 7 oranges each week so as to meet the requirement.

RDA is the recommended daily allowance that defines the level of the essential nutrients that a person consumes for a healthy lifestyle that is defined by Food and Nutrition so as to meet the required nutrient amount.

Given,

RDA of vitamin C = 60 mg/day

100 gm orange = 70 mg Vitamin C

So for one week, it is calculated as:

7 × 60 = 420 mg

The vitamin C in 100 gm oranges = 0.0007 and 1 oz = 28.3495 grams.

So, 3 oz = 3 × 28.3495 grams = 85048.5 mg

The amount of vitamin C in 85048.5 mg is calculated as:

0.0007 × 85048.5 = 59.53 mg

Number of oranges to be consumed each week = 420 ÷ 59.53 =7

Therefore, 7 oranges must be consumed in a week.

A nurse is performing an otoscopic examination on a client. Which finding would the nurse document as abnormal

Lemur [1.5K]

the abnormalities the nurse can document during the otoscopic examination are immobility of the tympanic membrane and middle ear effusion.

<h3>What is otoscopy?</h3>

Otoscopy can be defined as a clinical procedure used in the examination of the structures of the ear, particularly the external auditory canal, tympanic membrane, and even the middle ear.

Clinicians carryout otoscopy during routine wellness physical exams and the evaluation of specific ear complaints

During the otoscopic examination, the clinician utilizes an otoscope, also to see through or to visualize the ear anatomy.

The abnormalities that can be documented include;

Immobility of the tympanic membrane moves in response to pressure.
The detection of middle ear effusion

Thus, the abnormalities the nurse can document during the otoscopic examination are immobility of the tympanic membrane and middle ear effusion.

How to find the equation of a line with one point and no slope

adelina 88 [10]

Answer: the "y=mx+b" form (called the slope-intercept form of the equation of a line).

Explanation: Finding the equation for a line is a common problem in geometry and trigonometry. There are two common situations where you are asked to find the equation for a line: either you'll be provided with one point on the line and the slope of the line, or you'll be provided two points on the line.

The "b" value (called the y-intercept) is where the line crosses the y-axis.

So point (x1, y1) is actually at (0, b)

and the equation becomes:

Start with

y − y1 = m(x − x1)

(x1, y1) is actually (0, b):

y − b = m(x − 0)

Which is:

y − b = mx

Put b on other side:

y = mx + b

A carrier that transmit a disease

AnnyKZ [126]

Answer:

An asymptomatic carrier

Explanation:

An asymptomatic carrier (healthy carrier or just carrier) is a person or other organism that has become infected with a pathogen, but that displays no signs or symptoms.

Although unaffected by the pathogen, carriers can transmit it to others or develop symptoms in later stages of the disease. Asymptomatic carriers play a critical role in the transmission of common infectious diseases such as typhoid, C. difficile, influenzas, and HIV. While the mechanism of disease-carrying is still unknown, researchers have made progress towards understanding how certain pathogens can remain dormant in a human for a period of time. A better understanding of asymptomatic disease carriers is crucial to the fields of medicine and public health as they work towards mitigating the spread of common infectious diseases.
