Nursing Elites

1. What type of dehydration occurs when the electrolyte deficit exceeds the water deficit?

• A. Isotonic dehydration
• B. Hypotonic dehydration
• C. Hypertonic dehydration
• D. Hyperosmotic dehydration

Correct answer: B

Rationale: Hypotonic dehydration occurs when the loss of electrolytes exceeds the loss of water, leading to a decrease in plasma osmolarity. This often occurs when sodium loss is greater than water loss, as in diarrhea or vomiting.

2. During a funduscopic examination of a school-age child, the nurse notes a brilliant, uniform red reflex in both eyes. The nurse should recognize that this is which?

• A. A normal finding
• B. A sign of a possible visual defect and a need for vision screening
• C. An abnormal finding requiring referral to an ophthalmologist
• D. A sign of small hemorrhages, which usually resolve spontaneously

Correct answer: A

Rationale: A brilliant, uniform red reflex in both eyes is a normal finding, indicating that the retina is healthy and there are no significant obstructions in the visual pathway.

3. In addition to injuries, what are the leading causes of death in adolescents ages 15 to 19 years?

• A. Suicide and cancer
• B. Suicide and homicide
• C. Drowning and cancer
• D. Homicide and heart disease

Correct answer: B

Rationale: Suicide and homicide are significant causes of death in adolescents, highlighting the need for mental health and violence prevention programs.

4. After a 7-year-old with acute diarrhea has been rehydrated with oral rehydration solutions, what type of diet should the nurse recommend following rehydration?

• A. Regular diet
• B. Fruit juices
• C. High carbohydrate diet
• D. BRAT diet (bananas, rice, apples, and toast or tea)

Correct answer: A

Rationale: After rehydration, a regular diet is generally recommended to ensure proper nutrition and recovery. A regular diet includes a balanced intake of all food groups and nutrients. Fruit juices may be too high in simple sugars and lack necessary nutrients, which can exacerbate diarrhea. While a high carbohydrate diet may be beneficial in some cases, a regular diet is more comprehensive. The BRAT diet, consisting of bananas, rice, apples, and toast or tea, was previously recommended for diarrhea, but it lacks adequate protein and fat, so a regular diet is now preferred for overall better nutrition and recovery.

5. 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.
