A patient in active labor is prescribed oxytocin 12 milliunits/min intravenously (IV). The IV bag contains 5 units of oxytocin in 500 mL of lactated Ringer’s solution.
How many mL/hour should the nurse set the infusion pump to? (Enter numerical value only) .
The Correct Answer is ["0.72"]
Step 1 is to calculate the total amount of oxytocin in the IV bag. This is done by multiplying the total volume of the bag by the concentration of oxytocin. In this case, the bag contains 5 units of oxytocin in 500 mL, so the concentration is 5 units ÷ 500 mL = 0.01 units/mL.
Step 2 is to convert the prescribed dose from milliunits/min to units/hour. There are 1000 milliunits in a unit and 60 minutes in an hour, so 12 milliunits/min = 12 ÷ 1000 units/min = 0.012 units/min. Then, 0.012 units/min × 60 min/hour = 0.72 units/hour.
Step 3 is to calculate the infusion rate in mL/hour. This is done by dividing the prescribed dose in units/hour by the concentration of oxytocin in units/mL. So, 0.72 units/hour ÷ 0.01 units/mL = 72 mL/hour. Therefore, the nurse should set the infusion pump to 72 mL/hour.

Correct Answer is B
Explanation
The correct answer is choice B: Thick, muffled voice.
Choice B rationale: A thick, muffled voice is a characteristic symptom of epiglottitis. The inflammation and swelling of the epiglottis cause an obstruction in the airway, leading to changes in the child's voice quality.
Choice A rationale: High-pitched wheezing is typically associated with conditions affecting the lower airways, such as asthma or bronchiolitis. Epiglottitis primarily affects the upper airway, causing stridor (a high-pitched, harsh sound during inhalation) rather than wheezing.
Choice C rationale: Purulent nasal discharge is not a typical symptom of epiglottitis. Epiglottitis usually presents with minimal or no secretions, while purulent discharge is more commonly seen in bacterial infections like sinusitis or pneumonia.
Choice D rationale: A productive cough is not a common symptom of epiglottitis. Coughing is associated with conditions affecting the lower respiratory tract, such as bronchitis or pneumonia. Epiglottitis primarily affects the upper airway, causing difficulty breathing and a characteristic "thick, muffled voice."
Correct Answer is C
Explanation
Choice A rationale
While assessing for bladder distention is important in general urinary assessment, it is not directly related to the observation of the infant voiding a urinary stream from the ventral surface of the penis.
Choice B rationale
Listening for bowel sounds is a part of the general abdominal assessment. However, it does not provide information related to the observation of the infant voiding a urinary stream from the ventral surface of the penis.
Choice C rationale
Documenting the observation is the correct action. The nurse has observed that the infant voids a urinary stream from the ventral surface of the penis. This could indicate a condition such as hypospadias, where the urethral opening is on the underside of the penis. This is an important finding that should be documented and reported.
Choice D rationale
Checking the scrotum for testicular descent is part of the general assessment of the male genitalia. However, it does not provide information related to the observation of the infant voiding a urinary stream from the ventral surface of the penis.
