The new FDA SAFETY drug categorizing rule requires the use of three subsections in the prescribing information titled?
Pregnancy
Lactation
Female and males of reproductive potential
When teaching a pregnant woman about the use of drugs during pregnancy, which statement will the nurse include?
C.
Drug transfer to the fetus is most likely to occur during the last trimester of pregnancy. Exposure of a fetus to drugs is most detrimental during the first trimester of pregnancy, and fetuses are at greatest risk for drug-induced developmental defects during the first trimester of pregnancy. Pregnant women need to take medications to control situations such as high blood pressure.
Factors Affecting Pediatric Drug Dosages:
there are 5
Skin is thin and permeable.
Stomach lacks acid to kill bacteria.
Lungs have weaker mucus barriers.
Body temperatures less well regulated, and dehydration occurs easily.
Liver and kidneys are immature, impairing drug metabolism and excretion.
Older Adults Absorption:
Gastric pH is ___acidic
Gastric Emptying is ____
Movement through GI tract is slowed because of ____ muscle tone & activity
Blood flow to GI is _____
Absorptive surface of GI tract is ____
less
slowed
decreased
reduced or decreased
reduced
Medication Administration Considerations: Evaluation, what to look for?
Observe & Monitor both therapeutic & adverse effects
The nurse caring for a pediatric patient calculates the safe range for the prescribed medication. Based on the nurses calculations, the dose ordered exceeds the high limit. What is the nurse’s next action?
A.
The nurse should contact the prescriber immediately and before administering the medications. Giving only half the prescribed dose is making a prescribed order which is not within the scope of practice for the nurse. Pharmacy cannot make treatment changes without the direction of the prescriber.
What does the nurse identify as a pharmacokinetic change that occurs in older adults?
D.
In older adults, the gastric pH is less acidic because of a gradual reduction in the production of hydrochloric acid in the stomach, fat content is increased because of decreased lean body mass, and there is decreased production of proteins by the aging liver and reduced protein intake. It is correct that the number of intact nephrons decreases in older adults
