Digoxin levels need to be monitored closely when the following medication is started:
- A. Loratadine
- B. Diphenhydramine
- C. Ipratropium
- D. Albuterol
Correct Answer: D
Rationale: Albuterol , a beta-agonist, can increase digoxin levels by enhancing its effects, requiring close monitoring; antihistamines and ipratropium have minimal impact.
Zero order kinetics is seen with
- A. Phenytoin
- B. Phenobarbital
- C. Erythromycin
- D. Digoxin
Correct Answer: A
Rationale: Phenytoin exhibits zero-order kinetics at high doses (rate is constant, not proportional).
In today's health care environment there is often more contact between the patient and the nurse than between the patient and the physician. How does this increased patient contact impact drug therapy?
- A. Choosing the best medication to treat the patient's condition
- B. Assessing the patient's preferred communication strategies
- C. Assessing the therapeutic success of the drug therapy
- D. Reducing dosage quickly when adverse effects arise
Correct Answer: C
Rationale: More contact allows nurses to assess therapy success through observation and patient feedback.
Colestipol comes in a powdered form. The patient is taught to:
- A. Take the powder dry and follow it with at least 8 ounces of water
- B. Take it with a meal to enhance its action on fatty food
- C. Mix the powder with 4 to 6 ounces of milk or fruit juice
- D. Take after the evening meal to coincide with cholesterol synthesis
Correct Answer: C
Rationale: Mixing colestipol with liquid improves palatability and administration.
The processes involved in dynamic equilibrium are key elements in the nurse's ability to determine what?
- A. Dosage scheduling
- B. Amount of solution for mixing parenteral drugs
- C. Timing of other drugs the patient is taking
- D. How long the patient has to take the drug
Correct Answer: A
Rationale: These processes are key elements in determining the amount of drug (dose) and the frequency of dose repetition (scheduling) required to achieve the critical concentration for the desired length of time. The processes in dynamic equilibrium are not key elements in determining the amount of diluents for intramuscular (IM) drugs; they do not aid in the timing of the other drugs the patient is taking or how long the patient has to take the drug.
