Question 1 of 5
A child who weighs 55 pounds receives a prescription for isoniazid 10 mg/kg/day by mouth (PO) once a day. The bottle is labeled, 'Isoniazid Oral Solution, USP 50 mg per 5 mL.'. How many mL should the nurse administer?
Correct Answer: 25
Rationale: Weight is 55 lbs ÷ 2.2 = 25 kg. Dosage is 10 mg/kg/day * 25 kg = 250 mg/day. Solution is 50 mg/5 mL, so 250 mg ÷ 50 mg * 5 mL = 25 mL.
Question 2 of 5
An adolescent client who has successfully managed hemophilia for the past 10 years is evaluated by the nurse. Which behavior best evidences the client's adjustment to the disorder as an adolescent?
Correct Answer: C
Rationale: Serving as a counselor indicates successful self-management and the ability to support others, reflecting strong adjustment. Ice storage, extra pads, and slow chewing are less comprehensive indicators of adaptation.
Question 3 of 5
A patient was received one hour after delivering a 9 lb 1 oz (4.1 kg) female baby. Her vital signs are as follows: Temperature 100.4° F (38° C) orally, Heart rate 86 beats/minute, Respiratory rate 16 breaths/minute, Blood pressure 102/12 mm Hg, Pain 4 on a 0 to 10 pain scale. She was assisted to the bathroom where she voided 150 mL of clear yellow urine. Lochia rubra is moderate with small clots, no foul odor noted. The fundus is firm at the umbilicus. The episiotomy edges are well approximated, with no redness, edema, drainage, or ecchymosis. There is no pain, redness, or swelling in the calves. A 1,000 mL bag of lactated Ringer's solution containing 10 units of oxytocin is infusing via an 18-gauge peripheral IV in the left forearm at 125 mL per hour, with 500 mL remaining in the bag. The IV is patent, without redness or swelling, and can be discontinued when this bag's infusion is complete.
Correct Answer: -
Rationale: No specific action is required as all findings are within normal postpartum parameters. Vital signs, lochia, fundus, episiotomy, and IV status are stable, indicating routine monitoring is sufficient.
Question 4 of 5
The nurse is caring for a child who has had a unilateral long-leg cast applied for the correction of club foot. What is the most important action for the nurse to perform?

Rationale: Monitoring capillary refill assesses circulation, critical to prevent complications like tissue necrosis from cast compression.
Question 5 of 5
A client at 28-weeks gestation whose hemoglobin level is 10.7 g/dL (107 g/L) and hematocrit is 32.3% (0.323 volume fraction), tells the nurse that she eats plenty of green vegetables. When the client asks the nurse how the pregnancy might affect the laboratory findings, which information should the nurse provide?
Correct Answer: B
Rationale: Pregnancy increases plasma volume, diluting red blood cells and causing physiological anemia, explaining the low hemoglobin and hematocrit.
