A client prescribed prazosin hydrochloride asks the nurse why the first dose must be taken at bedtime. Which response by the nurse is based on the understanding of the first dose use of prazosin hydrochloride?
- A. Treatment with prazosin hydrochloride results in drowsiness.
- B. Treatment with prazosin hydrochloride can cause dependent edema.
- C. Prazosin hydrochloride should be taken when the stomach is empty.
- D. Treatment with prazosin hydrochloride can cause dizziness or possible syncope.
Correct Answer: D
Rationale: Prazosin is an alpha-adrenergic blocking agent. 'First-dose hypotensive reaction' may occur during early therapy, which is characterized by dizziness, lightheadedness, and possible loss of consciousness. The occurrence of these effects is better tolerated if the client is in bed. This also can occur when the dosage is increased. This effect usually disappears with continued use or the dosage is decreased.

A primary health care provider prescribes 1000 mL of normal saline to infuse at 100 mL/hour. The drop factor is 10 drops/mL. The nurse should set the flow rate at how many drops per minute?
Correct Answer: 17
Rationale: It will take 10 hours for 1000 mL to infuse at 100 mL/hour (1000 mL ÷ 100 mL = 10 hour × 60 min = 600 min). Next, use the intravenous (IV) flow rate formula. Formula: Total volume × Drop factor ÷ Time in minutes. 1000 mL × 10 Drops/mL = 10,000 ÷ 600 min = 16.6, or 17 Drops/minute.
The nurse is preparing to administer eardrops to an infant. The nurse should plan to proceed by taking which step to assure the appropriate instillation of the medication?
- A. Pull down and back on the auricle, and direct the solution onto the eardrum.
- B. Pull up and back on the earlobe, and direct the solution toward the wall of the ear canal.
- C. Pull up and back on the auricle, and direct the solution toward the wall of the ear canal.
- D. Pull down and back on the auricle, and direct the solution toward the wall of the ear canal.
Correct Answer: D
Rationale: The infant should be turned on the side with the affected ear uppermost. With the nondominant hand, the nurse pulls down and back on the auricle. The wrist of the dominant hand is rested on the infant's head. The medication is administered by aiming it at the wall of the ear canal rather than directly onto the eardrum. The infant should be held or positioned with the affected ear uppermost for 10 to 15 minutes to retain the solution. In the adult, the auricle is pulled up and back to straighten the auditory canal.
