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. The nurse is caring for a child with a urinary tract infection who is on intravenous gentamicin (Garamycin). What interventions should the nurse plan for this child with regard to this medication? (Select all that apply.)

• A. Encourage fluids.
• B. Monitor urinary output.
• C. Monitor sodium serum levels.
• D. All above

Correct answer: D

Rationale: Gentamicin is an aminoglycoside antibiotic that requires monitoring of serum peak and trough levels to avoid toxicity, particularly nephrotoxicity and ototoxicity. Encouraging fluids and monitoring urinary output are also crucial to minimize the risk of kidney damage.

3. The clinic nurse is teaching parents about physiologic anemia that occurs in infants. What statement should the nurse include about the cause of physiologic anemia?

• A. Maternally derived iron stores are depleted in the first 2 months.
• B. Fetal hemoglobin results in a shortened survival of red blood cells.
• C. The production of adult hemoglobin decreases in the first year of life.
• D. Low levels of fetal hemoglobin depress the production of erythropoietin.

Correct answer: B

Rationale: Physiologic anemia is caused by the transition from fetal to adult hemoglobin, with fetal hemoglobin having a shorter lifespan, leading to a temporary decrease in red blood cells.

4. The nurse is teaching parents about diarrhea in young children. A parent asks the nurse what causes most cases of diarrhea in young children. How should the nurse respond?

• A. Rotavirus
• B. Giardia
• C. Shigella
• D. Salmonella

Correct answer: A

Rationale: Rotavirus is the most common cause of diarrhea in young children, particularly those under the age of 2. Giardia, Shigella, and Salmonella can also cause diarrhea, but in the context of young children, Rotavirus is the primary pathogen responsible for diarrheal illnesses.

5. What is characteristic of a neonate’s vision?

• A. Pupils react to light
• B. Tear glands function
• C. Blink reflex is absent
• D. Ciliary muscles are mature

Correct answer: A

Rationale: The correct answer is A: 'Pupils react to light.' Newborns' pupils do react to light, indicating that the visual pathway is functioning. However, a neonate's vision is still developing, and they can only focus on objects close to their face. Choice B is incorrect because tear glands are functional at birth. Choice C is incorrect because the blink reflex is present in neonates and helps protect their eyes. Choice D is incorrect as neonates' ciliary muscles are not fully developed.
