1. What are the side effects of first-generation over-the-counter (OTC) antihistamines like diphenhydramine (Benadryl) and hydroxyzine (Atarax) in infants and children?
- A. Reye's syndrome.
- B. cholinergic effects.
- C. paradoxical CNS stimulation.
- D. nausea and diarrhea.
Correct answer: C
Rationale: The correct answer is paradoxical CNS stimulation. First-generation OTC antihistamines, such as diphenhydramine and hydroxyzine, can lead to paradoxical CNS stimulation in infants and children. This phenomenon is characterized by symptoms like excitement, euphoria, restlessness, and confusion, rather than the expected sedative effect. Due to this unexpected response, these antihistamines are used less frequently in pediatric populations. Reye's syndrome is a rare systemic response to a virus and is not a side effect of antihistamines. First-generation OTC antihistamines do not typically exhibit cholinergic effects. Nausea and diarrhea are uncommon side effects of these antihistamines and are less commonly observed than paradoxical CNS stimulation.
2. Which of the following observations is most important when assessing a client's breathing?
- A. presence of breathing and pulse rate
- B. breathing pattern and adequacy of breathing
- C. presence of breathing and adequacy of breathing
- D. patient position and adequacy of breathing
Correct answer: C
Rationale: The correct answer is the presence of breathing and adequacy of breathing. It is crucial not only to confirm that the client is breathing but also to ensure that the breathing is adequate for proper oxygenation. Choices A, B, and D are incorrect because while pulse rate, breathing pattern, and patient position are relevant aspects to consider, the most critical observations in assessing a client's breathing are the presence and adequacy of breathing.
3. What type of cells create exocrine secretions?
- A. alpha cells
- B. beta cells
- C. acinar cells
- D. plasma cells
Correct answer: C
Rationale: Acinar cells are responsible for creating exocrine secretions, such as enzymes and digestive juices. Alpha cells are found in the pancreas and are responsible for producing glucagon, beta cells produce insulin, and plasma cells are a type of white blood cell involved in immune responses. Therefore, the correct answer is acinar cells, as they specifically produce exocrine secretions.
4. Which deficiency in the mother has been primarily associated with neural tube defects in the fetus?
- A. Iron
- B. Folic acid
- C. Vitamin B12
- D. Vitamin E
Correct answer: B
Rationale: Folic acid deficiency in the mother has been primarily associated with neural tube defects in the fetus. Folic acid is crucial for the development of the neural tube in the early stages of pregnancy. Its deficiency can lead to neural tube defects, such as spina bifida or anencephaly. Iron deficiency is not directly related to neural tube defects but can cause other complications in pregnancy. Vitamin B12 is important for neurological function but is not the primary cause of neural tube defects. Vitamin E deficiency is not associated with neural tube defects in the fetus.
5. 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.
