1. What is a chemical reaction between drugs before their administration or absorption known as?

• A. a drug incompatibility
• B. a side effect
• C. an adverse event
• D. an allergic response

Correct answer: A

Rationale: A chemical reaction between drugs before their administration or absorption is termed a drug incompatibility. This phenomenon commonly happens when drug solutions are mixed before intravenous administration, but it can also occur with orally administered drugs. Choices B, C, and D are incorrect because side effects, adverse events, and allergic responses occur after the administration and absorption of drugs, not prior to it.

2. The anemias most often associated with pregnancy are:

• A. folic acid and iron deficiency.
• B. folic acid deficiency and thalassemia.
• C. iron deficiency and thalassemia.
• D. thalassemia and B12 deficiency.

Correct answer: B

Rationale: Folic acid and iron deficiency anemia are the most common types of anemia associated with pregnancy. Approximately 50% of pregnant women experience this type of anemia. Iron deficiency anemia during pregnancy typically results from the increased plasma volume, rather than a decrease in iron levels. Moreover, if a woman has iron deficiency anemia before pregnancy, it often worsens during pregnancy. Folic acid deficiency is also prevalent during pregnancy due to the increased demand for this nutrient to support fetal development. Thalassemia and B12 deficiency, while types of anemia, are not as commonly associated with pregnancy compared to folic acid and iron deficiency anemia, making them incorrect choices in this context.

3. How can light therapy be effective?

• A. overcoming weight problems.
• B. helping with allergies.
• C. use in alternative medical treatments.
• D. working with sleep patterns.

Correct answer: D

Rationale: Light therapy can be effective in treating problems associated with sleep patterns, stress, moods, jaundice in newborns, and seasonal affective disorders. While light therapy is not typically used for overcoming weight problems or helping with allergies, it is specifically known for its benefits in regulating sleep patterns. Therefore, the correct answer is 'working with sleep patterns.' Choices A, B, and C are incorrect as light therapy is not commonly utilized for overcoming weight problems, helping with allergies, or as a general alternative medical treatment.

4. When teaching a patient with COPD pulmonary exercises, what should be done?

• A. Teach pursed-lip breathing techniques.
• B. Encourage repetitive heavy lifting exercises to increase strength.
• C. Limit exercises due to respiratory acidosis.
• D. Take breaks every 10-20 minutes during exercises.

Correct answer: A

Rationale: The correct answer is to teach pursed-lip breathing techniques. Pursed-lip breathing helps to decrease the volume of air expelled by keeping the airways open longer, making it easier for patients with COPD to breathe out. Encouraging heavy lifting exercises (Choice B) is not suitable for patients with COPD as it can lead to increased shortness of breath. Limiting exercises due to respiratory acidosis (Choice C) is not correct; instead, exercises should be tailored to the patient's tolerance. Taking breaks every 10-20 minutes (Choice D) is not specific to the management of COPD pulmonary exercises.

5. What is one characteristic of human immunodeficiency virus (HIV)?

• A. The presence of circulating antibodies that neutralize HIV is evidence of exposure to HIV.
• B. HIV replication occurs intracellularly.
• C. HIV integrates its genetic material into the host cell's DNA.
• D. DNA replication is irrelevant to HIV.

Correct answer: C

Rationale: The correct answer is C. HIV integrates its genetic material into the host cell's DNA. The virus uses the enzyme reverse transcriptase to make a DNA copy of its RNA, which is then inserted into the genetic material of the infected cell. Choice A is incorrect because the presence of antibodies does not indicate immunity to HIV but rather exposure to the virus. Choice B is incorrect as HIV replication occurs intracellularly, inside the host cell. Choice D is irrelevant to the characteristics of HIV.
