A nurse is checking laboratory results for a client. Which of the following laboratory findings indicates hypervolemia?

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.

A. Dependent edema may occur in some cases of pericarditis but is not typically a priority finding compared to chest pain, which can indicate cardiac compromise.

B. A pericardial friction rub is a classic finding in pericarditis but is not necessarily the priority over the chest pain, which requires immediate attention.

C. A paradoxical pulse (pulse amplitude decreasing during inspiration) can occur in pericarditis but is not typically as concerning as substernal chest pain.

D. Substernal chest pain is a common and significant symptom of pericarditis, and assessing and managing the pain is a priority to ensure adequate cardiac function and alleviate discomfort.
