A client who weighs 76.5 kg is ordered hydromorphone 0.2 mg/kg/day intravenous push divided as needed every 6 hours. Available supply is 1 mg/mL. How many milliliters would the nurse administer in one dose? Round the answer to the nearest tenths place. Record the numeric answers only.
The Correct Answer is ["3.8"]
Calculate the total daily desired dose in milligrams (mg).
Total daily desired dose (mg) = Desired dose (mg/kg/day) × Weight (kg)
= 0.2 mg/kg/day × 76.5 kg
= 15.3 mg/day.
Determine the number of doses per day.
Doses are ordered every 6 hours, so Number of doses per day = 24 hr / 6 hr
= 4 doses/day.
Calculate the dose per administration in milligrams (mg).
Dose per administration (mg) = Total daily desired dose (mg) / Number of doses per day
= 15.3 mg / 4 doses
= 3.825 mg.
Available concentration of the medication = 1 mg/mL.
Calculate the volume in milliliters (mL) to administer per dose.
Volume (mL) = Desired dose per administration (mg) / Available concentration (mg/mL)
= 3.825 mg / 1 mg/mL
= 3.825 mL.
Round the answer to the nearest tenths place.
= 3.8 mL.

Correct Answer is B
Explanation
A. On the stomach with a pillow under her breasts: Sleeping on the stomach is not recommended during pregnancy as it becomes increasingly uncomfortable and impractical as pregnancy advances due to the growing uterus.
B. On the side with the weight of the uterus on the bed: This is the recommended position for pregnant women, especially in the second and third trimesters. Sleeping on the left side is particularly beneficial as it improves blood circulation, reduces pressure on the vena, and promotes better blood flow to the placenta and fetus.
C. On the back with a pillow under the knees and hips: Sleeping on the back is generally not recommended after the first trimester because the weight of the uterus can compress the major blood vessels, such as the inferior vena cava, reducing blood flow to the fetus.
D. On the back with a pillow under the head: While this position may be comfortable, sleeping on the back during pregnancy can lead to reduced blood flow to the fetus, especially in the later stages of pregnancy, and is generally not recommended. The side position is preferred.
Correct Answer is C
Explanation
A. Talk to the infant in a special way every day: While it is important to talk to the infant and engage with them, the emphasis should be on consistency, regular interaction, communication and responsiveness rather than just speaking in a special way.
B. Keep the infant stimulated with many toys: While providing toys for stimulation is helpful, the most critical aspect of development during the first year is emotional connection and security, which comes from consistent, responsive caregiving, not from many toys.
C. Respond to the infant consistently: Consistency in responding to the infant's needs fosters a sense of security and trust. It helps the infant develop a healthy attachment, which is a crucial developmental task in the first year.
D. Expose the infant to many caregivers to help the infant learn variability: Too many caregivers can lead to insecurity and confusion. It is important for infants to have stable, consistent caregivers in their early years to build trust and attachment.
