Try Naxlex NCLEX-RN (Free-Trial)

A nurse is caring for a preschooler who has heart failure and a new prescription for furosemide 4 mg/kg every 8 hr. The child weighs 16 kg (35 lb). Available is furosemide oral solution 40 mg/5 mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["8"]

Calculation:

  • Calculate the desired dose in milligrams (mg) per administration.

Desired dose (mg) = 4 mg/kg × 16 kg

     = 64 mg.

Available concentration of the medication = 40 mg/5 mL.

  • Calculate the volume in milliliters (mL) to administer per dose.

Volume (mL) = Desired dose (mg) / (Available concentration (mg) / Available volume (mL))

         = 64 mg / (40 mg / 5 mL)

        = 8 mL.

Correct Answer is D

Explanation

A. "You should position the car seat at a 30-degree angle." The correct angle for rear-facing car seats is 45 degrees. A 30-degree angle may cause the infant’s head to fall forward, increasing the risk of airway obstruction.
B. "You should place a folded blanket to pad the back of the infant's head." Extra padding behind or around the infant's head is not recommended as it may interfere with the seat’s effectiveness and safety in a crash.
C. "You should use a car seat with a four-point harness." The recommended harness system is a five-point harness, which provides more secure restraint at the shoulders, hips, and between the legs.
D. "You should place the retainer clip at the level of the infant's armpits." Correct placement of the retainer (chest) clip is at armpit level. This ensures that the harness straps stay positioned over the shoulders, reducing the risk of injury during a crash.

Correct Answer is C

Explanation

A. A school-age child who has Haemophilus influenzae type b disease: Haemophilus influenzae type b typically requires droplet precautions, not contact precautions, unless the infection is invasive like meningitis.
B. An adolescent who has pneumonia: Pneumonia caused by most pathogens does not require contact precautions unless there are specific indications such as a highly contagious organism or a superimposed infection that mandates isolation.
C. An infant who has respiratory syncytial virus (RSV): RSV is highly contagious and spreads through respiratory secretions. Contact precautions are necessary to prevent transmission, especially in healthcare settings.
D. A preschooler who has tuberculosis: TB is transmitted through the air via respiratory droplets, so airborne precautions (including a negative pressure room and an N95 respirator) are necessary to prevent transmission.
