Nursing Elites

1. What laboratory finding should the nurse expect in a child with an excess of water?

• A. Decreased hematocrit
• B. High serum osmolality
• C. High urine specific gravity
• D. Increased blood urea nitrogen (BUN)

Correct answer: A

Rationale: Water excess typically leads to hemodilution, resulting in a decreased hematocrit. High serum osmolality and specific gravity would indicate dehydration, while elevated BUN could suggest renal impairment or dehydration, not fluid overload.

2. The nurse is conducting discharge teaching to an adolescent with a methicillin-resistant Staphylococcus aureus (MRSA) infection. What should the nurse include in the instructions?

• A. Avoid sharing of towels and washcloths
• B. All are applicable
• C. Use bleach when laundering towels and washcloths
• D. Take a daily bath or shower with an antibacterial soap

Correct answer: B

Rationale: Avoiding sharing of towels and washcloths, using bleach when laundering, and taking daily baths with antibacterial soap are critical to prevent the spread of MRSA. Cold water is not effective for laundering in these cases.

3. 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.

4. For a child with Kawasaki disease, which symptom is most indicative of the acute phase?

• A. Strawberry tongue
• B. Joint pain
• C. Rash
• D. Peeling skin

Correct answer: A

Rationale: The correct answer is A: Strawberry tongue. In Kawasaki disease, a 'strawberry tongue' is most indicative of the acute phase. This refers to the tongue appearing red and swollen with enlarged fungiform papillae, giving it a strawberry-like appearance. Joint pain (Choice B) is more commonly associated with other conditions like rheumatoid arthritis. Rash (Choice C) and peeling skin (Choice D) are also seen in Kawasaki disease but are not as specific to the acute phase as the presence of a strawberry tongue.

5. What is the most common piece of medical equipment that can transmit harmful microorganisms among patients?

• A. Thermometer
• B. Stethoscope
• C. Injection needle
• D. Disposable gloves

Correct answer: B

Rationale: The correct answer is B: Stethoscope. A stethoscope is commonly used between patients, and if not correctly disinfected, it can be a dangerous source of spreading microorganisms. Thermometers typically have barriers to prevent this type of transmission. Injection needles are discarded immediately after use and not reused, making them an unlikely source of transmission. Similarly, disposable gloves are not reused, so they are also not a common source of harmful microorganism transmission.
