RN Nursing Care of Children 2019 With NGN
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. Kimberly is having a checkup before starting kindergarten. The nurse asks her to do the “finger-to-nose test.” What is the purpose of this test?
- A. Deep tendon reflexes
- B. Cerebellar function
- C. Sensory discrimination
- D. Ability to follow directions
Correct answer: B
Rationale: The finger-to-nose test assesses cerebellar function, which is responsible for balance and coordination. The test evaluates how well the cerebellum controls motor functions and coordination. Choice A, deep tendon reflexes, is incorrect because this test does not assess reflexes but rather cerebellar function. Choice C, sensory discrimination, is incorrect as this test focuses on motor function rather than sensory abilities. Choice D, ability to follow directions, is incorrect since the test primarily assesses motor coordination and not cognitive skills related to following instructions.
3. What factor predisposes an infant to fluid imbalances?
- A. Decreased surface area
- B. Lower metabolic rate
- C. Immature kidney functioning
- D. Decreased daily exchange of extracellular fluid
Correct answer: C
Rationale: Infants have immature kidneys that are less efficient at concentrating urine, making them more susceptible to fluid imbalances. Their higher surface area to volume ratio also contributes to greater insensible fluid losses.
4. Which family theory explains how families react to stressful events and suggests factors that promote adaptation to these events?
- A. Interactional theory
- B. Family stress theory
- C. Erikson's psychosocial theory
- D. Developmental systems theory
Correct answer: B
Rationale: Family stress theory explains how families respond to stress and identifies factors that help families adapt to and manage stressful events effectively.
5. What time frame has the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) and American College of Obstetricians and Gynecologists recommended that pregnant adolescents and women who are not protected against pertussis receive the tetanus, diphtheria, and pertussis (Tdap) vaccine?
- A. Between 27 and 36 weeks of gestation or postpartum before discharge from the hospital
- B. During the first prenatal visit when pregnancy is confirmed
- C. The vaccine should be administered 24 hours prior to delivery
- D. This vaccine is only recommended during the first trimester
Correct answer: A
Rationale: The Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC) and American College of Obstetricians and Gynecologists recommend that pregnant adolescents and women without protection against pertussis should receive the Tdap vaccine ideally between 27 and 36 weeks of gestation or postpartum before discharge from the hospital. This timeframe allows for the development of antibodies in the mother to protect her and provide passive immunity to the infant. Administering the vaccine during the first trimester (Choice D) is not recommended as the optimal time is between 27 and 36 weeks. Choice B, during the first prenatal visit, is too early for optimal protection, and Choice C, 24 hours prior to delivery, does not provide enough time for the vaccine to be effective before birth.
