1. By what age does birth weight usually triple?

Correct answer: A

Rationale: The correct answer is A: 1 year. By the age of 1 year, a baby’s birth weight typically triples. This period allows for significant growth and development in infants. Choices B, C, and D are incorrect because birth weight does not usually triple by 1 month, 2 years, or 6 months of age, respectively.

2. A child with acetaminophen (Tylenol) poisoning has been admitted to the emergency department. What antidote does the nurse anticipate being prescribed?

Correct answer: D

Rationale: N-acetylcysteine is the specific antidote for acetaminophen poisoning, working by replenishing glutathione and preventing liver damage. The other options are antidotes for different types of poisoning (e.g., Fomepizole for methanol or ethylene glycol poisoning).

3. After the family, which has the greatest influence on providing continuity between generations?

Correct answer: B

Rationale: Schools play a significant role in providing continuity between generations by imparting cultural values, social norms, and knowledge to children.

4. Which best describes signs and symptoms as part of a nursing diagnosis?

Correct answer: D

Rationale: Signs and symptoms are cues and clusters derived from patient assessments that are used to form a nursing diagnosis, guiding the development of a care plan.

5. A teen with asthma asks the nurse why it is hard to breathe during an asthma attack. The nurse explains that exposure to a “trigger” results in which of these manifestations?

Correct answer: D

Rationale: The correct answer is D. Asthma triggers cause bronchoconstriction, airway inflammation, and increased mucus production, leading to difficulty breathing. This combination of manifestations results in narrowing of the airways, making it hard for the individual to breathe effectively. Choices A, B, and C are incorrect because during an asthma attack, bronchodilation, muscle relaxation, and decreased mucus production do not occur. Instead, the airways constrict, become inflamed, and produce excess mucus, contributing to the breathing difficulties experienced by individuals with asthma.
