A nurse is caring for a client ordered ceftazidime 1g IM every 6 hours. The drug comes in a vial with a powder which is reconstituted with 3mL of sterile water for a final concentration of 280 mg/mL. How many mi. will be drawn into the syringe for the dose ordered? Do not use leading zero (Round to the tenth)

Answer and Explanation

The Correct Answer is ["3.6"]

Given:

Desired dose: Ceftazidime 1 g IM every 6 hours

Available concentration: Ceftazidime 280 mg/mL

To find:

Volume to administer (in mL)

Step 1: Convert desired dose to milligrams

1 gram (g) is equal to 1000 milligrams (mg).

Multiply by 1000:

Desired dose (mg) = Desired dose (g) x 1000

Desired dose (mg) = 1 g x 1000 = 1000 mg

Step 2: Set up the proportion

We can use the following proportion to solve the problem:

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

Step 3: Substitute the values

Plugging in the given values, we get:

(1000 mg) / (280 mg/mL) = Volume to administer

Step 4: Simplify

To simplify, we can invert the denominator and multiply:

(1000 mg) x (1 mL / 280 mg) = Volume to administer

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

(1000 x 1 mL) / 280 = Volume to administer

Step 5: Calculate

Performing the multiplication and division, we get:

1000 mL / 280 = Volume to administer

3.57 mL ≈ Volume to administer

Step 6: Round to the nearest tenth

3.6mL

Correct Answer is ["A","C","E"]

Explanation

A) Presence of a two-vessel umbilical cord:
The presence of a two-vessel umbilical cord (instead of the normal three vessels, which includes two arteries and one vein) is a significant finding that requires follow-up. A two-vessel cord can be associated with fetal anomalies, particularly with renal, cardiac, or chromosomal conditions. Therefore, it requires further evaluation to rule out any underlying conditions and ensure proper organ development.

B) Molding of the skull:
Molding of the skull is a normal and expected finding in newborns following a vaginal birth, especially after a long or difficult delivery. It refers to the temporary reshaping of the fetal skull bones as they overlap to pass through the birth canal. This is typically self-correcting and resolves within a few days, so no follow-up is needed for molding.

C) Asymmetry of ears:
Asymmetry of the ears can indicate congenital anomalies, such as craniofacial syndromes or other physical deformities. Although some degree of asymmetry can occur in newborns, especially in the first hours of life, persistent or significant asymmetry should be evaluated further. It may indicate an abnormality that requires follow-up or assessment by a specialist.

D) Tongue extending past the lower lip:
A tongue that extends past the lower lip is a normal finding in newborns, as babies are still developing their oral reflexes and muscle tone. This is not a cause for concern, and no follow-up is required unless other feeding issues arise. It's important to differentiate between normal tongue movements and more serious concerns like tongue-tie (ankyloglossia), but this is not indicative of a problem by itself.

E) Diminished breath sounds on one side:
Diminished breath sounds on one side of the chest can indicate a serious issue, such as a pneumothorax, diaphragmatic hernia, or other respiratory concerns. This finding warrants immediate follow-up, as the newborn could be experiencing a respiratory distress condition that needs urgent intervention and management. This is a significant finding requiring immediate evaluation.

A. Palmer grasp rettex B. Babinski C. Rooting reflex: D. Moro reflex

Correct Answer is D

Explanation

A) Palmer grasp reflex:
The palmer grasp reflex is a primitive reflex in which a newborn will grasp an object placed in their hand. While this reflex is present at birth, it typically disappears by 5-6 months of age, not by 3-4 months. The Moro reflex, which is more related to startle and sudden movements, is the correct answer in this case.

B) Babinski reflex:
The Babinski reflex, in which the toes fan out when the sole of the foot is stroked, is present at birth but typically disappears by 12 months. This reflex is an indicator of neurological development, and its presence beyond the first year could suggest neurological concerns, but it is not the reflex in question here.

C) Rooting reflex:
The rooting reflex occurs when the newborn turns their head and opens their mouth in response to cheek stimulation, typically to find the nipple for breastfeeding. This reflex is present at birth and usually disappears by 3-4 months, which is similar to the timing mentioned in the question.

D) Moro reflex:
The Moro reflex is a startle reflex in which the infant spreads their arms and then pulls them back in when they feel a sudden loss of support or a loud noise. This reflex is present at birth and typically disappears by 3-4 months of age. It is considered a classic primitive reflex that fades as the infant's nervous system matures.
