Q

The right documentation

A
  • The right documentation refers to the charting of the time when the medication was given.
  • This needs to be charted immediately after the client has taken his/her medication
  • The nurse needs to witness the client taking the medication before she can sign off
  • This documentation should be placed on the medication record under the correct date and time.

Q

The Right Reason

A
  • refers to the nurses’ knowledge as to why the patient is on the medication
  • The nurse verifies that the medication ordered is correct for the clients illness or diagnosis
  • The nurse can refer to the CPS under “drug uses” to determine that this is an appropriate medication for the reason in which this patient is being treated

Q

The Right Frequency

A
  • The nurse must know why a medication is ordered for certain times of the day and whether the time schedule can be altered
  • Medications that must act at certain times are given priority (ie. Insulin should be given at a precise interval before a meal)
  • Give medications according to their action: ie. Sleeping pills are given at bedtime whereas as diuretics are given in the morning

Q

Absorption

peds

A

Gastric pH less acidic (-increase abrop rate)

Gastric emptying is slowed (-peristalsis is slower)

Topical absorption faster through the skin (thin and more permeable)

Intramuscular absorption faster (-because there is more fluid) and irregular (-developing muscle)

More drug enters the brain because of the immature blood-brain barrier (-watch baby for neurological e

Q

Distribution

peds

A

TBW (total body water) is 70% to 80% in full-term infants, 85% in premature newborns, 64% in children 1 to 12 years of age

Greater TBW means fat content is lower

Decreased level of protein binding (more free drug in the tissues)

Q

Metabolism

peds

A

Liver immature, does not produce enough microsomal enzymes
Less Cytochrome P-450 enzyme is produced (necessary for metabolism of drugs) ( –the drug becomes more potent)

29
Q

. The child receives a dose of 1 teaspoon per directions according to his weight of 28 lb. Later, when his 5 yr-old sister needs a dose, she receives 1.5 teaspoons because her weight is 45 lb.
