Nursing Elites

1. Which laboratory test would be most important for the nurse to assess when caring for a toddler suspected of having cystic fibrosis?

• A. Liver enzymes
• B. Serum calcium
• C. Sweat chloride test
• D. Urine creatinine

Correct answer: C

Rationale: The sweat chloride test is the primary diagnostic test for cystic fibrosis. Cystic fibrosis is characterized by abnormal transport of chloride and sodium across epithelial cell membranes, leading to increased chloride in sweat. This test is crucial for diagnosing cystic fibrosis in suspected cases. Liver enzymes (Choice A), serum calcium (Choice B), and urine creatinine (Choice D) are not specific tests for cystic fibrosis and would not provide the necessary information for diagnosis in this case.

2. Which parental statement indicates correct understanding of information presented regarding the prevention of iron deficiency anemia in infants?

• A. "We will add green leafy vegetables to our child’s low-iron formula."
• B. "We will discontinue the use of vitamin C supplements by 6 months of age."
• C. "We will begin an iron-fortified infant cereal at 4 to 6 months of age."
• D. "We will introduce cow’s milk by 6 months of age."

Correct answer: C

Rationale: The correct answer is C. Introducing iron-fortified cereal between 4 to 6 months of age is a recommended practice to prevent iron deficiency anemia in infants. Iron-fortified infant cereals are a good source of iron for infants. Choices A and B are incorrect because adding green leafy vegetables to low-iron formula and discontinuing vitamin C supplements do not directly address the prevention of iron deficiency anemia. Choice D is incorrect because cow's milk should be avoided before 12 months of age as it is low in iron and can lead to intestinal blood loss, increasing the risk of iron deficiency anemia.

3. When assessing a family, the nurse determines that the parents exert little or no control over their children. This style of parenting is called which?

• A. Permissive
• B. Dictatorial
• C. Democratic
• D. Authoritarian

Correct answer: A

Rationale: Permissive parenting is characterized by parents exerting little or no control over their children, leading to a lack of boundaries and structure.

4. Nursing care of children focuses on improving quality by:

• A. Improving sanitation
• B. Focusing on curing childhood illnesses
• C. Addressing problems caused by communicable disease
• D. Providing a holistic environment for optimal growth and development

Correct answer: D

Rationale: The correct answer is D because nursing care for children should encompass a holistic approach that considers not only physical health but also emotional, social, and developmental aspects. Providing a holistic environment promotes optimal growth and development by addressing all these dimensions. Choices A, B, and C are incorrect because while sanitation, curing illnesses, and addressing communicable diseases are important aspects of child healthcare, they do not encompass the comprehensive care provided by a holistic approach.

5. 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.
