Nursing Elites

1. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

• A. Metabolic acidosis
• B. Respiratory alkalosis
• C. Metabolic and respiratory acidosis
• D. Metabolic and respiratory alkalosis

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

2. What factor predisposes an infant to fluid imbalances?

• A. Decreased surface area
• B. Lower metabolic rate
• C. Immature kidney functioning
• D. Decreased daily exchange of extracellular fluid

Correct answer: C

Rationale: Infants have immature kidneys that are less efficient at concentrating urine, making them more susceptible to fluid imbalances. Their higher surface area to volume ratio also contributes to greater insensible fluid losses.

3. Which should the nurse teach to parents regarding oral health of children? (Select all that apply.)

• A. Fluoridated water should be used.
• B. Early childhood caries is a preventable disease
• C. All options are correct
• D. Dental hygiene should begin with the first tooth eruption

Correct answer: C

Rationale: Fluoridated water helps prevent caries, early childhood caries is preventable, and dental hygiene should start with the first tooth eruption.

4. An infant is born with anencephaly. Based on the knowledge of this diagnosis, what information does the nurse consider when interacting with the family?

• A. Many treatment options exist.
• B. Immediate surgery is necessary.
• C. The condition is incompatible with life.
• D. The child will have permanent disabilities.

Correct answer: C

Rationale: The correct answer is C: 'The condition is incompatible with life.' Anencephaly is the most serious neural tube defect where both hemispheres of the brain are absent. It is incompatible with life, as there are no medical or surgical treatment options available. While some infants with mature brain stem function can maintain vital functions for a short period, anencephaly is ultimately not survivable. Choice A is incorrect as there are no treatment options for anencephaly. Choice B is incorrect as immediate surgery is not necessary for this condition. Choice D is incorrect as an infant with anencephaly will not have permanent disabilities since the condition is not compatible with life.

5. The nurse on a pediatric unit is writing guidelines for age-specific preparation of children for procedures based on developmental characteristics. What guideline is accurate?

• A. Inform toddlers about an upcoming procedure 2 hours before the procedure is to be performed.
• B. Inform school-age children about an upcoming procedure immediately before the procedure is scheduled to occur.
• C. Discourage parent presence during procedures on infants and toddlers.
• D. Use simple diagrams of anatomy and physiology to explain a procedure to a school-age child.

Correct answer: D

Rationale: Using simple diagrams helps school-age children understand what to expect in a procedure, catering to their developmental level and reducing anxiety. Informing toddlers too early can increase anxiety, and parents' presence is generally comforting, not discouraging.
