Questions and Answers
- 1.
Nonprescription topical antibiotics can be used to prevent bacterial infections, but not to treat them.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Nonprescription topical antibiotics are effective in preventing bacterial infections. However, they are not suitable for treating existing bacterial infections. This is because topical antibiotics are generally designed to target and kill bacteria on the surface of the skin, rather than penetrating deeper into the body to eliminate an infection. For treating bacterial infections, oral or systemic antibiotics are typically prescribed by a healthcare professional to ensure proper and thorough eradication of the infection.Rate this question:

Which of the following would be the most reasonable situation in which to recommend counterirritants?
- A.
Muscle stiffness
- B.
Dry skin
- C.
Contact dermatitis
- D.
Eczema
- E.
Atopy
Correct Answer
A. Muscle stiffnessExplanation
Counterirritants are substances that create a mild irritation or sensation on the skin, which can help to distract from or alleviate pain in deeper tissues. Muscle stiffness is a condition characterized by tightness and discomfort in the muscles. Since counterirritants work by providing a distracting sensation, they would be most reasonable to recommend in the situation of muscle stiffness, where the goal is to provide relief from the discomfort and promote relaxation of the affected muscles.Rate this question:

A week ago a patient came into your pharmacy with an acute allergic contact dermatitis on her finger where she was wearing a ring containing nickel. You recommended hydrocortisone cream and gave her suggestions for non-drug therapy. Today the rash is crusty, itchy, and hyperpigmented because...
- A.
The patient did not clean the rash properly
- B.
Hydrocortisone is too occlusive
- C.
The patient did not use wet compresses
- D.
It will take weeks to heal completely
- E.

Correct Answer
D. It will take weeks to heal completelyExplanation
The reason the rash is crusty, itchy, and hyperpigmented is because it will take weeks to heal completely. Allergic contact dermatitis can take time to resolve, especially if the allergen (in this case, nickel) continues to come into contact with the skin. The symptoms of crustiness, itchiness, and hyperpigmentation are common during the healing process. It is important for the patient to continue using the hydrocortisone cream as directed and to avoid further exposure to nickel to promote healing.Rate this question:

Children's skin absorbs drug more easily than adults' skin.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Children's skin is more permeable and absorbs substances more easily compared to adults' skin. This is because children have a thinner stratum corneum, the outermost layer of the skin, which acts as a barrier to prevent the entry of substances into the body. Additionally, children have a higher surface area to body weight ratio, which increases the absorption rate of drugs. Therefore, it is true that children's skin absorbs drugs more easily than adults' skin.Rate this question:

Chris has dermatitis where his bike helmet chin strap has been rubbing his skin. His mother has been treating the rash. It seemed to be getting better, but over the last two days, it has become redder and slightly swollen, and Chris says it hurts. What condition has probably just developed?
- A.
Bacterial infection
- B.
Chronic dermatitis
- C.
Xerosis
- D.
Tinea corporis
- E.

What is the etiology of atopic dermatitis?
- A.
Contact with an allergen in the environment causes T-cells in the skin to stimulate an immune response.
- B.
The skin develops cracks from excessive dryness, allowing bacteria to enter.
- C.
Contact with a chemical in the environment stimulates the immune system via direct damage to leukocytes.
- D.
Damage to the stratum corneum from a chemical in the environment allows bacteria to enter.
- E.
Mast cells in the skin have a hypersensitivity response and release histamine.
Correct Answer
E. Mast cells in the skin have a hypersensitivity response and release histamine.Explanation
Atopic dermatitis is a type of skin condition that is characterized by inflammation and itching. The etiology, or cause, of atopic dermatitis is believed to involve an abnormal immune response. Mast cells are immune cells that are involved in allergic reactions. In atopic dermatitis, mast cells in the skin have a hypersensitivity response, meaning they are overly sensitive to certain triggers. When these triggers are encountered, such as allergens or irritants, the mast cells release histamine, which causes inflammation and itching. This immune response plays a key role in the development of atopic dermatitis.Rate this question:

How often should wet compresses be used?
- A.
Several times a week
- B.
Daily
- C.
Twice a day
- D.
Five times a day
- E.
Continuously
Correct Answer
D. Five times a dayExplanation
Wet compresses should be used five times a day. This frequency allows for regular application of the compresses, ensuring that they remain effective in providing relief or treatment. Using wet compresses several times a week or daily may not provide enough consistent relief, while using them twice a day may not be frequent enough for certain conditions. Continuous use of wet compresses may lead to skin irritation or other adverse effects. Therefore, five times a day strikes a balance between regular use and avoiding excessive application.Rate this question:

- A.
48 hours
- B.
3 days
- C.
5 days
- D.
