The mother of a 2-month-old baby tells the nurse, "I'm worried because my baby isn't able to sit independently." Which response by the nurse would be appropriate?
"It's a bit too soon. Most babies sit steadily at 4 months"
"Once the first tooth comes in, sitting independently will soon follow"
"That's not unusual because most babies do not sit by themselves until about 8 months"
"That's interesting because most babies sit steadily at 3 months"
The Correct Answer is C
A. "It's a bit too soon. Most babies sit steadily at 4 months": While 2 months is certainly too early for independent sitting, at 4 months, babies often sit with support but true independent, steady sitting typically develops by 6 to 8 months.
B. "Once the first tooth comes in, sitting independently will soon follow": There is no correlation between the eruption of the first tooth and sitting independently. Sitting independently is more related to motor development, not teething.
C. "That's not unusual because most babies do not sit by themselves until about 8 months": While infants can begin to sit with support around 4-6 months, true independent, steady sitting (without support and for extended periods) is typically achieved around 6 to 8 months of age.
D. "That's interesting because most babies sit steadily at 3 months": It is too early for most babies to sit independently at 3 months. Most babies develop the ability to sit independently between 6 to 8 months.

Correct Answer is A
Explanation
A. "Nothing feels nicer than a hot sauna after exercise": Hot saunas should be avoided during pregnancy, especially in the first trimester, as they can raise the body temperature to unsafe levels, potentially leading to dehydration, overheating, or harm to the developing fetus.
B. "The gym gets hot and stuffy by midmorning": While the temperature of the gym may be uncomfortable, it is not inherently unsafe unless the environment becomes excessively hot or poorly ventilated. The concern here would be ensuring the client avoids overheating by taking breaks and staying hydrated.
C. "I'm learning to play table tennis": Table tennis is a low-impact activity that is generally safe during pregnancy. It does not involve high-intensity or risky movements that could cause harm to the pregnant individual or the baby.
D. "I limit exercising to low-impact aerobics": Low-impact aerobics is generally considered a safe form of exercise during pregnancy, as it minimizes stress on the joints and reduces the risk of injury. This comment indicates that the client is making appropriate exercise choices.
Correct Answer is ["2.2"]
Explanation
Convert the patient's weight from pounds (lb) to kilograms (kg).
Weight in kg = 38 lb / 2.2 lb/kg
= 17.2727 kg.
Calculate the total desired dose in milligrams (mg).
Desired dose (mg) = Desired dose (mg/kg) × Weight (kg)
= 6.25 mg/kg × 17.2727 kg
= 107.954 mg.
Available concentration of the medication = 50 mg/mL.
Calculate the volume in milliliters (mL) to administer.
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 107.954 mg / 50 mg/mL
= 2.15908 mL.
Round the answer to the nearest tenths place.
= 2.2 mL.
