Question 1 of 5

The healthcare provider prescribes Amoxicillin 500mg PO every 8hrs for a child who weighs 22 pounds. The available suspension is labeled Amoxicillin Suspension 250mg/5ml. The recommended maximum dose is 50mg/kg/24hr. How many mL should the nurse administer in a single dose based on the child's weight?

Correct Answer: A

Rationale: To calculate the dose for the child weighing 22 pounds, first convert the weight to kg: 22 lbs � 2.2 = 10 kg. The maximum dose based on weight would be 10 kg 50 mg/kg/24hr = 500 mg/24hr. Since the medication is prescribed every 8 hours, the dose for each administration would be 500 mg � 3 doses = 166.67 mg. As the available suspension is 250mg/5ml, the nurse should administer 166.67 mg � 250 mg/mL = 0.67 mL per dose. However, since it's not practical to administer a fraction of a milliliter, the nurse should round up to the nearest appropriate dose, which is 10mL.

Question 2 of 5

The nurse instructs a laboring client to use accelerated-blow breathing. The client begins to complain of tingling fingers and dizziness. What action should the nurse take?

Correct Answer: C

Rationale: Tingling fingers and dizziness are symptoms of hyperventilation, which can occur with accelerated-blow breathing. Instructing the client to breathe into her cupped hands can help rebreathe exhaled carbon dioxide, which can alleviate the symptoms by restoring the proper balance of oxygen and carbon dioxide in the blood. This intervention can be effective in managing the client's hyperventilation without the need for additional medical interventions at this point.

Question 3 of 5

A father watching the admission of his newborn to the nursery notices that eye ointment is placed in the infant's eyes. He asks what is the purpose of the ointment. The nurse would be correct in stating that the purpose of the ointment is:

Correct Answer: A

Rationale: The correct answer is A: Prevent eye infection. Eye ointment, usually containing erythromycin, is applied to prevent neonatal conjunctivitis, which can be caused by bacteria present in the birth canal. It is not used to dilate the pupil, clear the infant's vision, or prevent herpes infection.

Question 4 of 5

During a newborn assessment, which symptom would indicate respiratory distress if present in a newborn?

Correct Answer: A

Rationale: Flaring of the nares is a classic sign of respiratory distress in newborns. It indicates that the newborn is working hard to breathe, and immediate attention should be given to assess and address the respiratory status of the infant.

Question 5 of 5
