Question 1 of 5
A drug with a half life of 12 hours is administered by continuous intravenous infusion. How long will it take for the drug to reach 90% of its final steady-state level?
Correct Answer: C
Rationale: When a drug is administered by continuous intravenous infusion, it will take approximately 4-5 half-lives for it to reach 90% of its final steady-state level. In this case, the drug has a half-life of 12 hours, so it will take 4 half-lives (12 hours x 4 = 48 hours) for the drug to reach 90% of its final steady-state level. Therefore, the drug will reach 90% of its final steady-state level after 48 hours of continuous infusion.
Question 2 of 5
what is the classi昀椀cation of HEPARIN:
Correct Answer: C
Rationale: Heparin is a commonly used anticoagulant medication. It works by inhibiting the formation of blood clots in the body. Anticoagulants like heparin are frequently used to prevent and treat conditions such as deep vein thrombosis (DVT), pulmonary embolism, and during certain medical procedures to reduce the risk of clot formation. Heparin is not used to treat hypertension, diabetes, or as a laxative.
Question 3 of 5
The client is about to start the treatment for juvenile rheumatoid arthritis. Before the administration of etanercept (Enbrel), it is important for the nurse to:
Correct Answer: A
Rationale: Etanercept is administered via injection, and some formulations may contain latex in the packaging or delivery system. Assessing for a latex allergy is crucial to prevent allergic reactions. While vaccinations and travel plans are important considerations, they are not as critical as ensuring the client's safety regarding potential allergens. Avoiding people who recently received etanercept is not a standard precaution.
Question 4 of 5
Which of the following is the only medication that is approved for the management of amyotrophic lateral sclerosis?
Correct Answer: D
Rationale: Riluzole is the only FDA-approved drug for ALS, extending survival by inhibiting glutamate release, reducing excitotoxicity that accelerates motor neuron death. It modestly slows progression, offering a disease-modifying effect. Pramipexole and selegiline, dopamine-related drugs, treat Parkinson's, not ALS. Galantamine, a cholinesterase inhibitor, targets Alzheimer's cognition. Glatiramer manages MS via immune modulation. Riluzole's glutamate antagonism addresses ALS's neurodegenerative mechanism, backed by clinical trials, making it uniquely approved for this fatal condition.
Question 5 of 5
The nurse will administer medication to a school-age child. What is the preferred action by the nurse?
Correct Answer: A
Rationale: School-age kids (6-12) can understand drug purpose and side effects-e.g., 'This fights infection, you might feel sleepy'-fostering cooperation via cognitive growth. Threats like no recess breed resentment, not trust. Beverage choice helps but lacks education. Play delays, not enhances, administration. Teaching leverages development, improving adherence.
