A nurse is planning to administer an ophthalmic medication to a client. Which of the following actions will
minimize systemic absorption of the medication?
Apply light pressure to the inner canthus just after instilling the eye drops
Wipe the eye from the inner to the outer canthus with a sterile saline-moistened coton ball
Administer the medication drops directly into the lower conjunctival sac of each eye
Wait 5 min after instillation before instilling the drops in the other eye
None
None
The Correct Answer is A
Answer: A. Apply light pressure to the inner canthus just after instilling the eye drops.
Rationale:
A) Apply light pressure to the inner canthus just after instilling the eye drops.
Applying pressure to the inner canthus (the corner of the eye nearest the nose) helps occlude the nasolacrimal duct. This action reduces the systemic absorption of the medication by preventing it from draining into the nasal passages and subsequently into the systemic circulation, thus enhancing the local effect of the eye drops.
B) Wipe the eye from the inner to the outer canthus with a sterile saline-moistened cotton ball.
While this action may help remove excess medication or discharge, it does not minimize systemic absorption. Instead, wiping the eye could inadvertently spread the medication to other areas, increasing the chance of absorption rather than reducing it.
C) Administer the medication drops directly into the lower conjunctival sac of each eye.
While placing drops in the lower conjunctival sac is a standard practice for delivering ophthalmic medications, it does not directly influence systemic absorption. The main goal is to ensure adequate dosing in the eye, but systemic absorption can still occur if the drops drain into the nasolacrimal duct.
D) Wait 5 min after instillation before instilling the drops in the other eye.
Waiting between instillations is good practice to prevent dilution of the first dose and to allow for absorption. However, this action does not significantly impact systemic absorption. It focuses more on ensuring that the first dose is effective before administering a second dose.

Correct Answer is B
Explanation
The nurse should inform the client that they can use an adhesive remover when changing the colostomy skin barrier. Adhesive removers are helpful in gently removing the adhesive residue left behind by the previous ostomy appliance. This can make the process of changing the colostomy skin barrier more comfortable for the client and help prevent skin irritation or damage.
Explanation for the other options:
a. "You should scrub the skin around the colostomy when cleaning." Scrubbing the skin around the colostomy can be harsh and may cause skin irritation or damage. It is recommended to clean the peristomal skin gently using mild soap and water, followed by thorough drying.
c. "You will need a device to suction stool from the colostomy bag." Suctioning stool from the colostomy bag is not a routine procedure for colostomy care. Colostomy bags are designed to collect stool, and emptying the bag as needed is the appropriate method of management.
d. "You should empty the colostomy bag when it is three-fourths full." The timing of emptying the colostomy bag may vary for each individual. It is generally recommended to empty the colostomy bag when it is one-third to one-half full to prevent leakage or discomfort. The client should be educated on monitoring the bag and emptying it as necessary based on their own output and comfort level.
Correct Answer is ["A","B","E"]
Explanation
Compartment syndrome is a condition characterized by increased pressure within a closed anatomical space, such as a compartment in the leg. This increased pressure can compromise blood flow and nerve function. When assessing a client with a long-leg cast who reports severe pain, the nurse should be vigilant for signs and symptoms of compartment syndrome.
Option a is a correct answer because pallor (paleness) in the exposed portion of the left foot may indicate compromised blood flow due to increased pressure within the compartment.
Option b is a correct answer because the inability to move the left foot suggests impaired nerve function,
which can be a sign of compartment syndrome.
Option c is not a correct answer. Increased warmth is not typically associated with compartment syndrome; instead, it may suggest inflammation or infection.
Option d is not a correct answer. Ecchymosis (bruising) is not typically associated with compartment syndrome, as it is more commonly observed in cases of injury or trauma.
Option e is a correct answer because paresthesia (abnormal sensations like tingling or numbness) in the left foot can indicate nerve compression and is a potential symptom of compartment syndrome.
By identifying the presence of pallor, inability to move the foot, and paresthesia, the nurse can recognize indications of compartment syndrome and take appropriate actions to address the condition promptly.
