The nurse is administering a prescribed medication to neonatal client. Which factor is most likely to increase the risk for drug toxicity in this client?
The stomach acid has a lower pH level which results in increase absorption
The glomerular filtration rate (GFR) is increased causing rapid excretion
The liver enzyme system responsible for drug metabolism is not fully developed
The albumin levels are elevated due to rapid growth and protein binding is enhanced
The Correct Answer is C
A) The stomach acid has a lower pH level which results in increased absorption: While it is true that neonates have a lower gastric pH, which could affect the absorption of certain medications, this factor does not directly increase the risk for drug toxicity. Lower pH may increase absorption for some drugs, but it is not as critical in neonates as the immaturity of other organs, such as the liver and kidneys, which are responsible for drug metabolism and excretion.
B) The glomerular filtration rate (GFR) is increased causing rapid excretion: In neonates, the glomerular filtration rate (GFR) is actually decreased, not increased. This leads to slower excretion of medications, which can increase the risk for drug toxicity, especially for drugs that rely on renal elimination. This decreased renal function can result in accumulation of the drug in the bloodstream, potentially leading to toxicity.
C) The liver enzyme system responsible for drug metabolism is not fully developed: The liver enzyme system in neonates is immature, which significantly impacts the metabolism of drugs. Enzymatic activity is critical for breaking down medications to their active or inactive forms. Due to the underdeveloped liver function, drugs may not be metabolized properly, leading to a longer half-life and an increased risk for drug toxicity. This is a key factor in the increased risk of toxicity in neonatal clients.
D) The albumin levels are elevated due to rapid growth and protein binding is enhanced: Neonates typically have lower albumin levels, not elevated levels. Albumin is crucial for binding medications, and lower levels in neonates can result in more free (unbound) drug circulating in the bloodstream, which can increase the risk of drug toxicity. Elevated albumin would theoretically reduce this risk, but this is not typically the case in neonates.

Correct Answer is B
Explanation
A) The mother should not take any medication while breast feeding in order to prevent harm to the infant: This statement is too restrictive and not accurate. While some medications should be avoided during breastfeeding, many medications can be taken safely in small amounts. The focus should be on which medications are safe for breastfeeding, not a blanket prohibition on all medications. Some medications are compatible with breastfeeding, and the benefits of taking them may outweigh any potential risks.
B) Many medications cross into the breast milk in small amounts and could cause harm to the infant: This statement is correct. While many medications do pass into breast milk in small amounts, it’s important to recognize that some medications can pose risks to the infant depending on the type of medication, dosage, and timing of breastfeeding. Nurses should educate the mother to always consult with a healthcare provider before taking any medication while breastfeeding.
C) While medication can cross into the breast milk, no infants have ever been harmed because of this: This statement is not accurate. While many medications may pass into breast milk in small amounts, there are documented cases of infants being harmed by medications transferred via breastfeeding. It is crucial to be cautious and informed about the safety of medications taken during breastfeeding.
D) It is unlikely that a large enough amount of medication will cross into the breast milk and cause harm to the infant: While it may be true that in many cases, only small amounts of medication pass into breast milk, this statement oversimplifies the issue. The amount and type of medication, as well as the infant’s age, weight, and health, are all factors that need to be considered. Some medications may pose a significant risk to the infant, and careful evaluation is necessary.
Correct Answer is ["4"]
Explanation
Identify the desired dose: The doctor has ordered 40 mg of atorvastatin.
Identify the available tablet strength: Each tablet contains 10 mg of atorvastatin.
Set up the calculation: We need to find out how many tablets are needed to administer 40 mg of the medication.
We can use the following formula:
(Desired dose) / (Tablet strength) = Number of tablets
Plug in the values and calculate:
(40 mg) / (10 mg/tablet) = 4 tablets
