A nurse is analyzing the laboratory data on a client who has dehydration. Which finding should the nurse anticipate in a client who has fluid volume deficit?
Decreased serum osmolarity
Decreased hematocrit
Elevated blood urea nitrogen (BUN)
Lower urine specific gravity
The Correct Answer is C
A. Decreased serum osmolarity: Fluid volume deficit typically leads to an increase in serum osmolarity due to concentration of solutes in the blood, not a decrease.
B. Decreased hematocrit: Dehydration causes hemoconcentration, leading to an increase in hematocrit, not a decrease.
C. Elevated blood urea nitrogen (BUN): Dehydration results in decreased renal perfusion and concentration of urea in the blood, leading to elevated BUN levels.
D. Lower urine specific gravity: Dehydration causes increased urine concentration, resulting in higher urine specific gravity, not lower.

Correct Answer is D
Explanation
A. Not all clients with a history of MRSA will require antibiotics. Treatment depends on the presence of active infection, colonization, and other clinical factors.
B. There is no evidence to suggest that individuals can develop immunity to MRSA. MRSA remains a significant pathogen, and individuals with a history of MRSA remain susceptible to reinfection or colonization.
C. A protective environment is not typically required for clients with a history of MRSA. Standard precautions, including hand hygiene and appropriate use of personal protective equipment, are sufficient to prevent transmission.
D. Clients with a history of MRSA can still carry the bacteria on their skin or in their nasal passages and may transmit the infection to others, especially in healthcare settings. Therefore, it is important to adhere to infection control practices to prevent transmission.
Correct Answer is B
Explanation
A. "I should place a rolled blanket along each side of my baby's head in the car seat." - Incorrect. Placing rolled blankets on each side of the baby's head is not recommended as it can increase the risk of suffocation. Infants should be positioned in the car seat without any extra padding or blankets.
B. "I should place my baby's car seat rear-facing until 6 months of age." - Correct. Rear- facing car seats are recommended for infants until they reach at least 2 years of age or until they outgrow the weight and height limits specified by the car seat manufacturer. This position provides the best protection for the baby's head, neck, and spine in the event of a crash.
C. "I should put the car seat retainer clip at the level of my baby's belly button." - Incorrect.
The retainer clip should be positioned at armpit level to secure the harness straps properly.
D. "I should position my baby's car seat at a 90-degree angle in the car." - Incorrect. Car seats should be installed at the appropriate recline angle according to the manufacturer's
instructions, which may vary depending on the specific car seat model and the child's age and size.
