A nurse is preparing to administer an injection of 0.25 mg subcutaneous terbutaline to a client who is in preterm labor. The amount available is 1 mg/ml. How many ml should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero)

A. "We will switch our baby's car seat to forward-facing when they turn one.": Current guidelines recommend keeping infants and toddlers in a rear-facing car seat until they reach the maximum height or weight limit of the seat, often well past one year, to provide optimal protection in a crash.

B. "We will check the temperature of the car seat surface before placing our baby in the seat when it is hot out.": This statement shows good understanding. Car seat surfaces can become dangerously hot and cause burns. Checking the seat temperature ensures the baby’s safety and comfort before securing them inside.

C. "We will make sure to activate the air bag when we place the car seat in the front passenger seat.": Airbags can cause serious injury or death to infants in rear-facing car seats. Car seats should always be placed in the back seat, and airbags should be deactivated if absolutely necessary to place a seat in the front, which is discouraged.

D. "We will wrap our baby in a blanket under the car seat straps when it is cold out.": Placing a blanket under the straps can prevent the harness from fitting snugly and securely. Instead, the harness should be fastened correctly first, and then a blanket can be placed over the baby for warmth.

A. Hypertension: Hyponatremia typically leads to hypotension due to fluid shifts out of the vascular space rather than hypertension, especially if it is associated with hypovolemia. Low sodium levels can reduce blood volume and pressure, making hypertension an unlikely finding in this condition.

B. Muscle cramps: Muscle cramps are a common symptom of hyponatremia due to disrupted electrolyte balance affecting neuromuscular function. Low sodium levels impair muscle contraction and nerve signal transmission, leading to cramps, weakness, and fatigue.

C. Blurred vision: Blurred vision is not a typical manifestation of hyponatremia. While severe hyponatremia can cause neurological symptoms like confusion or seizures, visual disturbances like blurred vision are not primary signs linked to sodium imbalance.

D. Constipation: Constipation is more often associated with dehydration, immobility, or other electrolyte imbalances such as hypercalcemia. Hyponatremia primarily affects neuromuscular and central nervous system function rather than gastrointestinal motility.
