Nursing Elites

1. The mother of an infant diagnosed with bronchiolitis asks the nurse what causes the disease. How should the nurse respond?

• A. Respiratory syncytial virus (RSV)
• B. Haemophilus influenzae
• C. Parainfluenza
• D. Rotavirus

Correct answer: A

Rationale: The correct answer is A: Respiratory syncytial virus (RSV). RSV is the most common cause of bronchiolitis, especially in infants. Bronchiolitis is characterized by inflammation of the small airways in the lungs. Choice B, Haemophilus influenzae, is a bacterium that can cause respiratory infections but is not the primary cause of bronchiolitis. Choice C, Parainfluenza, is a common viral infection that can cause croup and other respiratory illnesses but is not the main cause of bronchiolitis. Choice D, Rotavirus, is a virus that primarily affects the gastrointestinal system, causing diarrhea and vomiting, and is not associated with bronchiolitis.

2. The nurse is preparing to assess a 10-month-old infant. He is sitting on his father's lap and appears to be afraid of the nurse and of what might happen next. Which initial actions by the nurse should be most appropriate?

• A. Initiate a game of peek-a-boo.
• B. Ask the infant's father to place the infant on the examination table
• C. Talk softly to the infant while taking him from his father
• D. Undress the infant while he is still sitting on his father’s lap

Correct answer: A

Rationale: Engaging the infant in a familiar game like peek-a-boo can help reduce fear and build rapport before starting the assessment.

3. The nurse is preparing to admit a 7-year-old child with Crohn disease. What clinical manifestations should the nurse expect to observe?

• A. Pain is common.
• B. Weight loss is severe.
• C. All are correct.
• D. Diarrhea is moderate to severe.

Correct answer: C

Rationale: The correct answer is C because Crohn's disease commonly presents with pain, severe weight loss, and moderate to severe diarrhea in affected individuals. Therefore, all the manifestations listed are typically observed in patients with Crohn's disease. Choice A alone is not sufficient as weight loss and diarrhea are also prominent symptoms. Choice B is incorrect as it only mentions weight loss, omitting other common manifestations. Choice D is also incorrect as it does not cover the full range of expected clinical signs in Crohn's disease.

4. Physiologically, the child compensates for fluid volume losses by which mechanism?

• A. Inhibition of aldosterone secretion
• B. Hemoconcentration to reduce cardiac workload
• C. Fluid shift from interstitial space to intravascular space
• D. Vasodilation of peripheral arterioles to increase perfusion

Correct answer: C

Rationale: In response to dehydration, the body compensates by shifting fluids from the interstitial spaces to the intravascular space to maintain blood pressure and perfusion to vital organs. Hemoconcentration and vasoconstriction are other compensatory mechanisms but are less immediate.

5. 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.
