A nurse is reinforcing teaching with a client with bacterial conjunctivitis of the right eye, and a prescription for an antibiotic ophthalmic ointment. Which of the following statements should the nurse make?
"Apply the ointment in a thin line into the conjunctival sac."
"Keep your eye open for 30 sec after instilling the ointment."
"Use a sterile glove and applicator to apply the antibiotic ointment."
"Always wipe from the outer to the inner canthus when wiping away secretions."
The Correct Answer is A
A) "Apply the ointment in a thin line into the conjunctival sac":
This instruction is correct for applying ophthalmic ointments. Placing the ointment in a thin line along the conjunctival sac ensures proper distribution and contact with the affected area.
B) "Keep your eye open for 30 sec after instilling the ointment":
Keeping the eye open for a brief period after instillation helps the ointment spread across the eye surface. This statement indicates understanding of the proper technique for applying ophthalmic ointments and does not require further instruction.
C) "Use a sterile glove and applicator to apply the antibiotic ointment":
Using a sterile glove and applicator ensures that the application is done in a sterile manner, reducing the risk of introducing further infection. This statement indicates a need for further instruction, as ophthalmic ointments are typically applied using clean hands or disposable, sterile applicators rather than sterile gloves.
D) "Always wipe from the outer to the inner canthus when wiping away secretions":
Wiping from the outer to the inner canthus helps prevent contamination of the unaffected eye. This statement demonstrates understanding of proper eye care techniques and does not require further instruction.

Correct Answer is ["7.5"]
Explanation
We can calculate the volume of potassium chloride solution to administer using the following steps:
Identify the prescribed dose: The nurse needs to administer 20 mEq of potassium chloride.
Identify the concentration of available solution: The potassium chloride liquid is available in a concentration of 40 mEq/15 mL. This means there are 40 milliequivalents (mEq) of potassium chloride in every 15 milliliters (mL) of the solution.
Set up a proportion to find the volume needed:
Desired dose (mEq) : Volume to administer (mL) = Concentration (mEq/mL)
Plug in the values:
20 mEq : Volume to administer (mL) = 40 mEq/15 mL
Solve for the volume:
To isolate the volume (mL), multiply both sides of the proportion by the volume unit (mL) and divide by the dose (mEq).
Volume to administer (mL) = (20 mEq) x (mL) / (40 mEq/15 mL)
We can simplify the calculation before dividing:
Volume to administer (mL) = (20 mEq x 15 mL) / 40 mEq
Volume to administer (mL) = 300 mL / 40 mEq
Volume to administer (mL) = 7.5 mL (round to one decimal place)
Therefore, the nurse should administer 7.5 mL of the potassium chloride solution.
Correct Answer is ["94"]
Explanation
To calculate the flow rate for the IV infusion, we can follow these steps:
Identify the total volume to be infused: The total volume of 0.9% sodium chloride (NaCl) solution is 750 mL.
Identify the infusion time: The nurse needs to administer the solution over 8 hours.
Calculate the flow rate: We need to find out how many milliliters (mL) per hour (hr) the IV pump should deliver.
Here's the formula:
Flow rate (mL/hr) = Total volume (mL) / Infusion time (hr)
Flow rate (mL/hr) = 750 mL / 8 hr
Flow rate = 93.75 mL/hr
Rounding the answer: Since we are dealing with medication administration, it's important to round to the nearest whole number to avoid inaccurate dosing. In this case, rounding down is appropriate.
Therefore, the nurse should set the IV pump to deliver 94 mL/hr.
