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 weighed 8 lb at birth and was 18 inches in length. What weight and length should the infant be at 5 months of age?

• A. 12 lb, 20 inches
• B. 14 lb, 21.5 inches
• C. 16 lb, 23 inches
• D. 18 lb, 24.5 inches

Correct answer: C

Rationale: By 5 months, an infant's weight should typically double from birth, and length should increase by approximately 50%.

3. When caring for a child with probable appendicitis, the nurse should be alert to recognize which sign or symptom as a manifestation of perforation?

• A. Anorexia
• B. Bradycardia
• C. Sudden relief from pain
• D. Decreased abdominal distention

Correct answer: C

Rationale: When caring for a child with probable appendicitis, sudden relief from pain is a critical sign that could indicate perforation of the appendix. Perforation results in the release of pressure and inflammation, leading to a temporary relief of pain. Anorexia (loss of appetite) and decreased abdominal distention are symptoms commonly associated with appendicitis itself, not perforation. Bradycardia (slow heart rate) is not typically a direct manifestation of appendicitis or its complications.

4. What is the recommended method to assess hydration status in infants?

• A. Capillary refill time
• B. Skin turgor
• C. Urine output
• D. Mucous membranes

Correct answer: C

Rationale: The correct answer is C: Urine output. Assessing urine output is a recommended method to determine hydration status in infants. Adequate urine output indicates good hydration, while decreased urine output may suggest dehydration. Capillary refill time (Choice A) is more indicative of circulatory status rather than hydration. Skin turgor (Choice B) is a useful assessment in adults but can be less reliable in infants. Checking mucous membranes (Choice D) can provide some information on hydration, but it is not as reliable as assessing urine output in infants.

5. The physician tells the parents of a 2-year-old that the child probably has RSV. The parents ask how the diagnosis will be confirmed. How should the nurse respond?

• A. We will swab your child's nose and send the secretions for testing.
• B. There is no specific test for RSV. The diagnosis is based on symptoms.
• C. We will send a viral culture to an outside lab for testing.
• D. There is no specific test for RSV. The diagnosis is based on symptoms.

Correct answer: A

Rationale: The correct answer is A. RSV is typically diagnosed by swabbing the nose and testing the secretions. This method helps confirm the presence of the respiratory syncytial virus. Choice B is incorrect because while symptoms are important in diagnosis, specific tests like swabbing for RSV do exist. Choice C is incorrect as sending a viral culture to an outside lab is not the primary method for diagnosing RSV. Choice D is a duplicate of choice B and is incorrect for the same reasons.
