Nursing Elites

1. An infant who has had diarrhea for 3 days is admitted in a lethargic state and is breathing rapidly. The parent states that the baby has been ingesting formula, although not as much as usual, and cannot understand the sudden change. What explanation should the nurse give the parent?

• A. Cellular metabolism is unstable in young children.
• B. The proportion of water in the body is less than in adults.
• C. Renal function is immature in children until they reach school age.
• D. The extracellular fluid requirement per unit of body weight is greater than in adults.

Correct answer: D

Rationale: The correct answer is D. Infants have a higher extracellular fluid requirement per unit of body weight, making them more susceptible to dehydration and electrolyte imbalances during illnesses such as diarrhea. Choice A is incorrect because cellular metabolism being unstable is not the primary explanation for the symptoms described. Choice B is incorrect as the proportion of water in the body alone does not fully explain the increased risk of dehydration in infants. Choice C is incorrect because while renal function is immature in children, it is not the most relevant factor in this scenario compared to the increased fluid requirements.

2. Which is the most appropriate nursing diagnosis for the child with acute glomerulonephritis?

• A. Risk for injury related to malignant process and treatment
• B. Fluid volume deficit related to excessive losses
• C. Fluid volume excess related to decreased plasma filtration
• D. Fluid volume excess related to fluid accumulation in tissues and third spaces

Correct answer: C

Rationale: The most appropriate nursing diagnosis for a child with acute glomerulonephritis is fluid volume excess related to decreased plasma filtration. Acute glomerulonephritis is characterized by inflammation of the glomeruli in the kidneys, leading to decreased plasma filtration and retention of fluid. This results in fluid volume excess rather than fluid deficit (choice B) or fluid accumulation in tissues and third spaces (choice D). The diagnosis of 'risk for injury related to malignant process and treatment' (choice A) is not directly related to the pathophysiology of acute glomerulonephritis.

3. A 3-year-old child with a history of frequent respiratory infections is being evaluated for cystic fibrosis. What diagnostic test should the nurse anticipate will be ordered?

• A. Chest X-ray
• B. Sweat chloride test
• C. Pulmonary function test
• D. Sputum culture

Correct answer: B

Rationale: The correct answer is the sweat chloride test. This test is crucial in diagnosing cystic fibrosis as it measures the amount of chloride in sweat, which is typically elevated in individuals with cystic fibrosis. A chest X-ray (Choice A) may show characteristic findings like hyperinflation or bronchiectasis, but it is not a definitive diagnostic test for cystic fibrosis. Pulmonary function tests (Choice C) may help assess lung function but are not specific for cystic fibrosis. Sputum culture (Choice D) may be used to identify specific pathogens causing respiratory infections but is not a primary diagnostic test for cystic fibrosis.

4. The nurse volunteering at a homeless shelter to assist families with children identifies homelessness as a risk preventing families from achieving positive outcomes in life. What family theory encompasses this approach to assessing family dynamics?

• A. Duvall's developmental theory
• B. Friedman's structural functional theory
• C. Von Bertalanffy's general system theory applied to families
• D. Resiliency model of family stress, adjustment, and adaptation

Correct answer: D

Rationale: The Resiliency model of family stress, adjustment, and adaptation focuses on identifying the elements of risks and protective factors that help families achieve positive outcomes. In this scenario, the nurse recognizing homelessness as a risk aligns with the resiliency model, which emphasizes how families cope and adapt in the face of stressors. Duvall's theory primarily focuses on family life cycle stages, Friedman's theory emphasizes the roles and functions within a family structure, and Von Bertalanffy's theory looks at families as complex systems rather than specifically addressing resilience in the face of stressors.

5. On the third day of hospitalization, the nurse observes that a 2-year-old toddler who had been screaming and crying inconsolably begins to regress and is now lying quietly in the crib with a blanket. What stage of separation anxiety has developed?

• A. Denial
• B. Despair
• C. Mistrust
• D. Rejection

Correct answer: B

Rationale: The correct answer is B: 'Despair'. In separation anxiety, the stage of despair is characterized by regression and withdrawal after the initial protest. The toddler's shift from intense crying to lying quietly with a blanket demonstrates this withdrawal behavior. Choice A, 'Denial', is incorrect as denial involves refusing to accept the reality of separation. Choice C, 'Mistrust', is incorrect as it relates to a lack of trust rather than the stage of separation anxiety described in the scenario. Choice D, 'Rejection', is incorrect as it does not reflect the behavior of the toddler in the scenario, which is more indicative of withdrawal and regression.
