Nursing interventions for patient's getting parenteral nutrition?

Monitor weight, fluid intake, urine output, vital signs, blood glucose, serum electrolytes, and complete blood count

Which characteristic may allow a drug to cross the blood-brain barrier?

Only drugs that are lipid soluble or have a transport system can cross the blood-brain barrier and reach therapeutic concentrations in brain tissue

A client has been prescribed supplemental iron tablets. What instruction is most appropriate for the nurse to include in teaching to maximize absorption?

Oral iron preparations are better absorbed if taken on an empty stomach

What substance is necessary to facilitate absorption of fat-soluble vitamins? Select all that apply.

Pancreatic lipase, Bile salts

Tube feeding supplements:

Patient in sitting position, solution at room temp ( cold will cause abdominal cramping), no more than 5oomL per feeding (vomiting) , should take 30-60 mins, tubes should be rinsed after each use and replaced ever 24h. DO NOT mix meds.

Acetaminophen Toxicity

Prevention: maximum daily dose is 4 g from all sources. Overdose causes hepatotoxicity. 24 to 48 hours after overdose, liver function tests begin to show increased levels. Gastric lavage and activated charcoal (If overdose detected within 4 hours after ingestion)

Aspirin

Reduce fever by acting on the hypothalamus Diminish inflammation Suppress platelet aggregation Low dose for Ischemic stroke, transient ischemic attack, angina, and acute myocardial infarction

The nurse is educating a client regarding a newly prescribed oral prescription with a name that includes initials SR. What information should the nurse provide concerning the drug's delivery system

Slow-release (SR) dosage forms absorb more slowly and maintain concentrations within an acceptable therapeutic range over a long period of time It provides for a more consistent serum level. It allows for less frequent dosing.

Absorption of a drug administered orally will take place primarily in what anatomical location?

Small intestine

COX-1 inhibitor has known protective effects on what organ?

Stomach, Kidneys

An adult client has told the nurse that vitamin supplements should be avoided because ''natural foods are the only good source of vitamins.'' What information about synthetic vitamins should be the basis of the nurse's response?

Synthetic vitamins are less expensive than some natural sources., Natural and synthetic sources of vitamins are equivalent in function.

VItamin K supplement

Take this vitamin only as directed by a health care provider. Keep intake of vitamin K-containing foods constant. Avoid sudden increases or decreases in the amounts of these foods. If taking warfarin, report any use of vitamin K to your health care provider. During warfarin therapy, intake of vitamin K-containing foods should remain constant.

How is pharmacodynamics best defined?

The action that the drug has on body cells

The client's admission blood work indicates a low creatinine clearance rate (CrCl). A low CrCl may have what implication for the client's pharmacotherapy?
