Nursing Elites

1. 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?

• A. Bronchodilation, muscle relaxation, and decreased mucus production
• B. Air trapping and hypo-inflation of the alveoli
• C. Air trapping and decreased blood flow to the upper airway
• D. Bronchoconstriction, airway inflammation, and excess mucus production

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.

2. An infant, age 5 months, is brought to the clinic by his parents for a well-baby checkup. What is the best advice that the nurse should include at this time about injury prevention?

• A. Keep buttons, beads, and other small objects out of his reach.
• B. Do not permit him to chew paint from window ledges because he might absorb too much lead.
• C. When he learns to roll over, you must supervise him whenever he is on a surface from which he might fall.
• D. Lock the crib sides securely because he may stand and lean against them and fall out of bed.

Correct answer: A

Rationale: Small objects are a choking hazard for infants, so it is crucial to keep them out of reach to prevent injury.

3. Play activities of the preschool-age child include:

• A. Having imaginary playmates
• B. Selective collection of objects
• C. Complex board games
• D. Associative play

Correct answer: A

Rationale: The correct answer is A, 'Having imaginary playmates.' Preschool-age children often engage in imaginative play, which includes creating imaginary friends or playmates. This type of play helps them develop creativity, social skills, and emotional expression. Choice B, 'Selective collection of objects,' may be more common in older children and is not a typical play activity for preschoolers. Choice C, 'Complex board games,' are usually beyond the developmental level of preschoolers as they require more advanced cognitive skills. Choice D, 'Associative play,' is a term used to describe a type of play where children play alongside each other but not necessarily together, which is different from the imaginative play involving imaginary playmates that preschoolers often engage in.

4. The clinic nurse is teaching parents about physiologic anemia that occurs in infants. What statement should the nurse include about the cause of physiologic anemia?

• A. Maternally derived iron stores are depleted in the first 2 months.
• B. Fetal hemoglobin results in a shortened survival of red blood cells.
• C. The production of adult hemoglobin decreases in the first year of life.
• D. Low levels of fetal hemoglobin depress the production of erythropoietin.

Correct answer: B

Rationale: Physiologic anemia is caused by the transition from fetal to adult hemoglobin, with fetal hemoglobin having a shorter lifespan, leading to a temporary decrease in red blood cells.

5. The presence of which pair of factors is a good predictor of a fluid deficit of at least 5% in an infant?

• A. Weight loss and decreased heart rate
• B. Capillary refill of less than 2 seconds and no tears
• C. Increased skin elasticity and sunken anterior fontanel
• D. Dry mucous membranes and generally ill appearance

Correct answer: D

Rationale: Dry mucous membranes and an ill appearance are good indicators of dehydration in infants, often correlating with a fluid deficit of at least 5%. Sunken fontanels and poor skin turgor are also indicative but were not options here.
