The most common method of administering medications is______? 18-4
- A.
Orally
- B.
Parentally
- C.
Topically
- D.
Intravenously
Correct Answer
A. OrallyExplanation
The most common method of administering medications is orally. This means that the medication is taken by mouth, usually in the form of a pill or liquid. Oral administration is preferred because it is convenient, non-invasive, and allows for easy absorption of the medication into the bloodstream through the digestive system. Other methods such as parenteral administration (injection), topical application (on the skin), and intravenous administration (directly into the veins) are less common and usually reserved for specific situations or conditions.Rate this question:

Correct Answer
C. ParenteralExplanation
Parenteral medications are introduced by injection. This route of administration bypasses the digestive system and delivers the medication directly into the bloodstream or tissues. Intravenous, intradermal, and subcutaneous injections are all examples of parenteral routes. Intravenous injections are administered directly into a vein, intradermal injections are given just below the skin surface, and subcutaneous injections are administered into the fatty layer of tissue just beneath the skin. These routes are used when medications need to be rapidly absorbed or when the medication cannot be taken orally.Rate this question:

In what form are medications introduced in to the body through inhalation? 18-5
- A.
Gas
- B.
Oral
- C.
Topical
- D.
All of the above
Correct Answer
A. GasExplanation
Medications introduced into the body through inhalation are in the form of gas. When inhaled, the medication is converted into a gas or vapor, which is then inhaled into the lungs. This allows the medication to be quickly absorbed into the bloodstream through the lungs' large surface area and provides a direct route to the target area, such as the respiratory system. Inhaled medications are commonly used to treat respiratory conditions like asthma or chronic obstructive pulmonary disease (COPD).Rate this question:

Correct Answer
C. 3Explanation
Medications typically have three names. The first name is the chemical or generic name, which describes the drug's composition. The second name is the brand or trade name, which is given by the pharmaceutical company marketing the drug. The third name is the International Nonproprietary Name (INN), which is assigned by the World Health Organization (WHO) and is used globally to ensure consistency in drug names. Therefore, medications commonly have three names to identify them.Rate this question:

Which of the following is NOT a way in which drugs are grouped? 18-7
- A.
By chemical characteristics
- B.

Correct Answer
B. By their brand namesExplanation
Drugs are typically grouped based on various factors such as their chemical characteristics, source, and their action on the body. However, drugs are not typically grouped by their brand names. Brand names are specific names given to drugs by pharmaceutical companies for marketing purposes and do not provide any information about the drug's chemical composition, source, or action on the body. Therefore, grouping drugs by their brand names is not a common practice.Rate this question:

Correct Answer
A. AstringentsExplanation
Astringents are medications that cause shrinkage of the skin and mucous membranes. They work by constricting blood vessels and reducing inflammation, leading to a tightening effect on the tissues. This can be beneficial in treating conditions such as acne, hemorrhoids, and minor skin irritations. Astringents are commonly used topically and can be found in various forms such as toners, lotions, and creams. They are not to be confused with emollients, which are moisturizers that help soften and soothe the skin.

What suppress the growth of microorganisms?18-10
- A.
Antiseptics
- B.
Disinfectants
- C.
Penicillins
- D.
Phenols
Correct Answer
A. AntisepticsExplanation
Antiseptics are substances that inhibit the growth and development of microorganisms. They are specifically designed to be used on living tissues, such as skin, to prevent infections. Antiseptics work by either killing the microorganisms or inhibiting their growth. They are commonly used in medical settings, such as hospitals and clinics, to sterilize wounds and prevent the spread of infections. Unlike disinfectants, which are used on surfaces and objects, antiseptics are generally milder and less toxic to human tissues. Therefore, antiseptics are effective in suppressing the growth of microorganisms and preventing infections.Rate this question:

Correct Answer
B. DisinfectantsExplanation
Disinfectants are agents that are used to disinfect inanimate objects and are primarily germicidal in their action. They are specifically designed to kill or inactivate microorganisms on surfaces, reducing the risk of infection or contamination. Unlike antiseptics, which are used on living tissues, disinfectants are intended for non-living objects such as countertops, floors, or medical instruments. Cephalosporins and sulfonamides, on the other hand, are types of antibiotics used to treat bacterial infections in humans and animals.Rate this question:

Correct Answer
D. EmollientsExplanation
Emollients are bland or fatty substances that can be applied to the skin to make it more pliable and soft. They help to moisturize and soothe the skin, preventing dryness and irritation. Emollients are commonly used in skincare products such as lotions, creams, and ointments to improve the texture and appearance of the skin. They work by forming a protective barrier on the skin's surface, trapping moisture and preventing it from evaporating. Emollients are especially beneficial for individuals with dry or sensitive skin, as they help to restore and maintain the skin's natural moisture balance.Rate this question:

- A.
Antisepotics
- B.
Antacids
- C.
Cepahlosporins
- D.
Phenols
Correct Answer
B. AntacidsExplanation
Antacids are used to counteract hyperacidity in the stomach. Hyperacidity is often caused by excessive production of stomach acid, leading to symptoms such as heartburn and indigestion. Antacids work by neutralizing the excess acid in the stomach, providing relief from these symptoms. They contain ingredients such as calcium carbonate, magnesium hydroxide, or aluminum hydroxide, which react with the acid to form salts and water. This helps to reduce the acidity levels and restore the normal pH balance in the stomach, alleviating the discomfort caused by hyperacidity.Rate this question:

Which of the following is a side effect of antihistamines?18-9
- A.
Nausea
- B.
Drowsiness
- C.
Uricaria
- D.
Tinnitis
Correct Answer
B. DrowsinessExplanation
Antihistamines are medications commonly used to treat allergies. One of the side effects of antihistamines is drowsiness. This is because antihistamines can cross the blood-brain barrier and affect the central nervous system, leading to sedation and drowsiness. This side effect is particularly common with first-generation antihistamines, while second-generation antihistamines are designed to be less sedating. Drowsiness caused by antihistamines can impair a person's ability to perform tasks that require alertness, such as driving or operating machinery. Therefore, it is important to be aware of this potential side effect when taking antihistamines.Rate this question:
