A mother asks whether or not she should be concerned that her baby never opens his mouth to breathe when his nose is so small. Which of the following is the nurse's best response?

"Babies usually breathe in and out through their noses so they can feed without choking."

"You are right. I will report the baby's small nasal openings to the pediatrician right away.*

*Everything about babies is small. It truly is amazing how everything works so well."

"The baby does rarely open his mouth but you can see that he isn't in any distress.

Answer and Explanation

The Correct Answer is A

A) "Babies usually breathe in and out through their noses so they can feed without choking.":
Newborns are obligate nasal breathers, meaning they primarily breathe through their noses rather than their mouths, which helps coordinate breathing with feeding. This nasal breathing mechanism helps prevent aspiration and ensures that babies can feed while still breathing. It is perfectly normal for a baby to primarily use their nose for breathing, especially in the early days of life, and no cause for concern should be raised about small nasal openings unless the baby is showing signs of respiratory distress.

B) "You are right. I will report the baby's small nasal openings to the pediatrician right away.":
A small nasal opening is common in newborns and is not usually a cause for alarm unless it interferes with breathing, feeding, or shows signs of a more significant anatomical issue. There is no immediate need to report it unless the baby is having trouble breathing or feeding. The nurse should offer reassurance instead.

C) "Everything about babies is small. It truly is amazing how everything works so well.":
While this response may seem comforting, it is not very informative. It dismisses the mother’s concern rather than providing a clear and educational explanation. Reassuring the mother with factual information about why babies breathe through their noses and how this works effectively for them would be more helpful.

D) "The baby does rarely open his mouth but you can see that he isn't in any distress.":
This response minimizes the importance of the mother’s question and doesn’t fully address her concern. While it’s true that babies rarely open their mouths to breathe, the explanation needs to focus on the physiological reasoning behind it. The nurse should also reassure the mother that nasal breathing is normal in newborns and not typically a concern unless signs of distress are present.

Correct Answer is ["0.5"]

Explanation

Given:

Desired dose: Vitamin K 0.5 mg IM

Available concentration: Vitamin K 1 mg/1 mL

To find:

Volume to administer (in mL)

Step 1: Set up the proportion

We can use the following proportion to solve the problem:

(Desired dose) / (Available concentration) = Volume to administer

Step 2: Substitute the values

Plugging in the given values, we get:

(0.5 mg) / (1 mg/1 mL) = Volume to administer

Step 3: Simplify

To simplify, we can invert the denominator and multiply:

(0.5 mg) x (1 mL / 1 mg) = Volume to administer

The "mg" units cancel out, leaving us with:

(0.5 x 1 mL) / 1 = Volume to administer

Step 4: Calculate

Performing the multiplication and division, we get:

0.5 mL / 1 = Volume to administer

0.5 mLVolume to administer

A. A rubella injection is advised B. A blood transfusion is advised C. The nurse should contact the provider for an antibiotic order an D. RhoGAM injection should be administered within 72 hours

Correct Answer is A

Explanation

A) A rubella injection is advised:
Since the rubella titer is non-immune, the woman is not protected against rubella, which is important to address during the postpartum period. The rubella vaccine is typically given to women who are non-immune to rubella after childbirth, but it is contraindicated during pregnancy because it is a live vaccine. The best action in this case would be to administer the rubella vaccine to the postpartum woman before discharge, with instructions to avoid becoming pregnant for at least 28 days after vaccination to prevent harm to a future fetus.

B) A blood transfusion is advised:
The hematocrit of 30% indicates that the woman has mild anemia, but it does not require immediate intervention like a blood transfusion. Normal hematocrit levels for postpartum women typically range between 32% and 42%. A transfusion would be indicated if the hematocrit were much lower (usually below 20-25%) or if there were symptoms of significant blood loss, which are not indicated in this case.

C) The nurse should contact the provider for an antibiotic order:
There is no indication from the provided laboratory results or the scenario that the woman requires antibiotics. Group B Streptococcus (GBS) was negative, which eliminates the need for prophylactic antibiotics. There is no mention of any infection risk requiring an antibiotic prescription, and since her GBS result is negative, antibiotics are not warranted.

D) RhoGAM injection should be administered within 72 hours:
RhoGAM (Rh immunoglobulin) is typically administered to a woman with Rh-negative blood who has given birth to an Rh-positive baby to prevent Rh sensitization in future pregnancies. In this case, the woman has an Rh-positive blood type (A+), so she does not need RhoGAM. RhoGAM would only be necessary if the woman had an Rh-negative blood type, which she does not.
