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 C
Explanation
Answer: C. Weigh the client each morning after voiding
Rationale:
A. Encourage the client to gain 2.3 kg (5 lb) per week:
A weight gain goal of 0.5 to 1 kg (1 to 2 lb) per week is considered safe and realistic. Gaining 2.3 kg (5 lb) weekly is too aggressive and may cause physical and psychological stress for the client.
B. Monitor the client for 15 min after meals:
Clients with anorexia nervosa are at risk for purging behaviors. Monitoring for only 15 minutes is insufficient. A 60-minute post-meal observation period is more appropriate to deter vomiting or excessive exercise.
C. Weigh the client each morning after voiding:
Daily weights, taken at the same time each morning after voiding and before eating, provide consistent and accurate data to monitor progress and detect manipulation or fluid shifts.
D. Reinforce teaching about healthy eating during meals:
Reinforcing education during meals can increase the client’s anxiety and resistance to eating. Teaching is best done separately from mealtimes to avoid associating eating with stress.
Correct Answer is D
Explanation
Choice A:
An absent dorsal pedal pulse would indicate a vascular problem such as arterial occlusion, not a deep vein thrombosis (DVT). In the case of DVT, blood flow in the veins is obstructed, but the arterial pulse, which is related to arterial circulation, should remain intact unless there is a separate arterial issue. Therefore, absent pulses are not characteristic of DVT.
Choice B:
Shiny, hairless skin is a sign typically associated with chronic arterial insufficiency, not DVT. This skin change occurs when there is poor arterial blood flow, which leads to a lack of nourishment for the skin, causing it to become thin and shiny. In contrast, DVT affects the veins and does not usually cause these skin changes in the acute phase.
Choice C:
Irregular, bulging veins are indicative of varicose veins or chronic venous insufficiency, not a DVT. Varicose veins occur when the veins become swollen and twisted due to weak or damaged valves. DVT, on the other hand, involves the formation of a clot in the deep veins and does not typically cause the veins to bulge visibly, especially in the early stages.
Choice D:
Dull, aching pain is a common symptom associated with deep vein thrombosis. This pain typically occurs in the affected extremity and is often described as a constant, aching sensation. The pain can worsen with movement or standing and is due to the inflammation and obstruction caused by the blood clot in the deep veins. This is a hallmark sign of DVT, along with swelling and redness in the affected limb.
