NurseDive Free Nursing Practice Question
The healthcare provider prescribes 500 mL intravenous (IV) bolus of 0.9% normal saline to be infused over 30 minutes. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only.)

Full Explanation
rate (mL/h) = volume (mL) / time (h).
In this case, the volume is 500 mL and the time is 0.5 h (30 minutes).
Plugging these values into the formula, we get: rate (mL/h) = 500 mL / 0.5 h = 1000 mL/h. Therefore, the nurse should set the infusion pump to 1000 mL/hour.

When assessing a newborn girl with salt-wasting congenital adrenal hyperplasia due to 21 hydroxylase deficiency, the nurse notes that the infant has an enlarged clitoris. Which intervention should the nurse implement?
A. Review transcutaneous bilirubin levels with a bilirubinometer.
Incorrect- Reviewing transcutaneous bilirubin levels is unrelated to the presence of an enlarged clitoris. Bilirubin levels are typically assessed to monitor jaundice in newborns.
B. Observe and palpate newborn's breast tissue for enlargement.
Incorrect- Observing and palpating breast tissue for enlargement is not relevant to the condition of salt-wasting congenital adrenal hyperplasia. Breast tissue enlargement would not be associated with this hormonal disorder.
C. Assess for signs of fluid retention and bilateral pedal edema.
Incorrect- Assessing for signs of fluid retention and bilateral pedal edema is important for monitoring for other conditions, but it is not relevant to the enlarged clitoris seen in this specific scenario.
D. Explain to mother that the finding is due to increased androgen.
Correct- Salt-wasting congenital adrenal hyperplasia is a genetic disorder that results in a deficiency of certain enzymes required for cortisol and aldosterone production. This deficiency leads to an overproduction of androgens, which can cause virilization of female external genitalia. The enlarged clitoris is a result of increased androgen levels. Explaining this finding to the mother provides her with accurate information about the condition and its effects on the infant's anatomy.

What factors are important in determining the level of hypoxemia that the child may have experienced during the submersion? Select all that apply.
A. The amount of time the child was submerged
Correct- The duration of submersion is a critical factor in determining the potential level of hypoxemia. Prolonged submersion leads to a higher risk of severe hypoxia and its associated complications.
B. Temperature of water
Incorrect- While water temperature can affect the body's response to submersion, it is not directly related to the level of hypoxemia. Hypoxemia primarily results from the lack of oxygen intake during submersion.
C. Whether or not anyone witnessed the fall into the pool
Correct- Witnessing the fall into the pool is important because immediate initiation of cardiopulmonary resuscitation (CPR) can improve the chances of a positive outcome. Bystander CPR can help maintain oxygenation and circulation until professional help arrives.
D. Oxygen concentration of the ambient air
Correct- The oxygen concentration in the surrounding air is crucial for oxygen delivery to the body's tissues. In cases of submersion, the availability of oxygen in the air the child is breathing plays a role in determining the level of hypoxemia.
E. The weight of the child
Incorrect- The weight of the child is not a significant factor in determining the level of hypoxemia during submersion. The primary determinants are factors like submersion duration, availability of oxygen, and prompt initiation of CPR.

Review H and P and nurse's notes.
What are the first four actions that the nurse should take?
A. Take the child's pulse
Correct- Assessing the child's pulse helps determine their cardiac status and whether they have a detectable heartbeat. This information is essential for deciding the appropriate interventions.
B. Place a cervical collar on the client
Correct- Placing a cervical collar is necessary if there is any suspicion of cervical spine injury due to the fall or submersion. This action helps stabilize the neck and prevent further damage to the spine.
C. Look for any open wounds
Correct- Checking for open wounds is important to assess for potential sources of bleeding or infection that may require immediate attention.
D. Call child protective services
Incorrect- While child safety is important, the immediate priority in this situation is assessing and stabilizing the child's medical condition. Child protective services may be involved later if there are concerns about the circumstances surrounding the incident.
E. Determine if the child's airway is clear
Correct- Assessing the airway is of utmost importance to ensure that the child can breathe. In cases of near-drowning, ensuring a clear airway is crucial for oxygenation.
F. Start a peripheral intravenous line
Incorrect- While establishing intravenous access may be important for certain interventions, it is not one of the immediate priorities in this situation. Ensuring the child's airway, breathing, and circulation take precedence.
