A client is to receive one liter of normal saline intravenously over six hours. The tubing delivers 15 drops per milliliter.
How many drops per minute should a nurse regulate the infusion to deliver?
42.
84.
100.
166.
The Correct Answer is B
To explain why, we need to use the formula for calculating the drip rate in drops per minute (dpm):
Volume of IV fluid (mL) x Drop Factor (drops/mL) / Time to run (h) x 60 (min/h) = Drip Rate (dpm)
In this question, the volume of IV fluid is one liter, which is equivalent to 1000 mL. The drop factor is 15 drops per mL, as given by the tubing.
The time to run is six hours, as ordered by the physician. Plugging these values into the formula, we get:
1000 mL x 15 drops/mL / 6 h x 60 min/h = 84 dpm
Therefore, the nurse should regulate the infusion to deliver 84 drops per minute.
Choice A is wrong because it gives a drip rate of 42 drops per minute, which is half of the correct answer.
This would result in delivering only 500 mL of normal saline in six hours, instead of one liter.
Choice C is wrong because it gives a drip rate of 100 drops per minute, which is more than the correct answer.
This would result in delivering 1.43 liters of normal saline in six hours, instead of one liter.
Choice D is wrong because it gives a drip rate of 166 drops per minute, which is almost double the correct answer.
This would result in delivering 1.99 liters of normal saline in six hours, instead of one liter.
Normal saline is a solution of 0.9% sodium chloride in water, which has the same osmolarity as blood plasma.
It is used to treat dehydration, shock, blood loss, and other conditions that require fluid replacement.
The normal range of sodium in blood is 135-145 mEq/L.

Correct Answer is B
Explanation
Using teach back method to assess understanding. This method involves asking the client to repeat back the information or demonstrate the skill that was taught, which helps to evaluate their comprehension and retention.
It also allows the nurse to correct any misunderstandings and reinforce key points.
Choice A is wrong because teaching handouts are written on an eighth grade reading level may not be appropriate for older adult clients who may have lower literacy levels or cognitive impairments. The nurse should use simple, common language and large-print handouts that reflect the verbal information presented.
Choice C is wrong because the teaching plan is based on nutrition, medications, and safety may not address the individual needs and preferences of the older adult clients. The nurse should consider the preadmission functional abilities, health goals, and learning styles of each client when developing the plan of care.
Choice D is wrong because websites, video chats, and cell phone applications are introduced for learning may not be suitable or accessible for older adult clients who may have limited technology skills or sensory impairments. The nurse should use visual aids, face-to-face communication, and written instructions to enhance learning.
Correct Answer is A
Explanation
The nurse should obtain a sputum culture specimen before administering any antibiotics to the client with bacterial pneumonia.
This is because the sputum culture can help identify the causative organism and the appropriate antibiotic therapy.
Administering antibiotics before obtaining the sputum culture can alter the results and lead to ineffective treatment.
Choice B is wrong because azithromycin is an antibiotic that should be given after obtaining the sputum culture.
Choice C is wrong because coughing and deep breathing are important interventions to promote airway clearance and gas exchange, but they are not the priority actions for this client.
Choice D is wrong because offering clear liquids can help prevent dehydration and thin secretions, but they are not the most urgent action for this client.
Normal ranges for blood urea nitrogen (BUN) are 7 to 20 mg/dL and for creatinine are 0.6 to
1.2 mg/dL.
Elevated levels of these substances can indicate renal impairment, which can be a complication of bacterial pneumonia.
The nurse should monitor these levels and report any abnormalities to the health care provider.
