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. When doing a nutritional assessment on a Hispanic family, the nurse learns that their diet consists mainly of vegetables, legumes, and starches. The nurse should recognize that this diet is which?

• A. Lacking in protein
• B. Indicating they live in poverty
• C. Providing sufficient amino acids
• D. Needing enrichment with meat and milk

Correct answer: C

Rationale: A diet rich in vegetables, legumes, and starches can provide sufficient amino acids, particularly when complemented with varied food sources to ensure a balanced intake of essential nutrients.

3. The LPN is assessing for fontanels on the head of a 6-month-old. Which fontanel is expected to still be present?

• A. Posterior
• B. Anterior
• C. Sphenoid
• D. Lambdoid

Correct answer: B

Rationale: The correct answer is B: Anterior. The anterior fontanel usually remains open until about 12-18 months of age, while the posterior fontanel closes by 2-3 months. Choices A, C, and D are incorrect as the posterior fontanel closes by 2-3 months of age, and the sphenoid and lambdoid fontanels are not typically assessed in routine infant head examinations.

4. What is the most common cause of acute gastroenteritis in children under 5 years?

• A. Salmonella
• B. Rotavirus
• C. Norovirus
• D. Shigella

Correct answer: B

Rationale: Rotavirus is the leading cause of acute gastroenteritis in children under 5 years. It leads to severe diarrhea and dehydration. Vaccination against rotavirus has significantly reduced the incidence of this disease, but it remains a major cause of morbidity in young children globally. Salmonella and Shigella can cause gastroenteritis, but they are less common in children under 5 years. Norovirus is also a common cause of gastroenteritis, but Rotavirus is the most prevalent in this age group.

5. An infant with short bowel syndrome will be on total parenteral nutrition (TPN) for an extended period of time. What should the nurse monitor the infant for?

• A. Central venous catheter infection, electrolyte losses, and hyperglycemia
• B. Hypoglycemia, catheter migration, and weight gain
• C. Venous thrombosis, hyperlipidemia, and constipation
• D. Catheter damage, red currant jelly stools, and hypoglycemia

Correct answer: A

Rationale: Infants with short bowel syndrome requiring prolonged total parenteral nutrition (TPN) are susceptible to central venous catheter infections, electrolyte losses, and hyperglycemia. Monitoring for these complications is crucial to prevent serious outcomes. Choices B, C, and D are incorrect because they do not reflect the common complications associated with prolonged TPN in infants.
