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 A
Explanation
Hyponatremia refers to a lower-than-normal level of sodium in the blood. Sodium is an essential electrolyte involved in various bodily functions, including maintaining fluid balance and transmitting nerve impulses. When sodium levels are low, it can lead to fluid imbalances, affecting the function of muscles and nerves. Muscle cramps are a common manifestation of hyponatremia and occur due to alterations in muscle excitability and contractility.
Constipation: Constipation is not typically associated with hyponatremia. It can occur due to various reasons, such as dietary factors, lack of physical activity, or other medical conditions, but it is not a direct consequence of low sodium levels.
Hypertension: Hyponatremia is not usually associated with hypertension (high blood pressure). Hypertension can be caused by several factors, including genetics, lifestyle, and certain medical conditions, but it is not directly related to low sodium levels.
Blurred vision: While blurred vision can occur in some medical conditions, such as diabetes or certain eye disorders, it is not a typical finding in hyponatremia. Visual disturbances are not a direct consequence of low sodium levels.
Correct Answer is D
Explanation
When a mother states that she should have her baby latch on to both the nipple and areola during breastfeeding, it demonstrates an understanding of the correct latch technique. A proper latch involves the baby taking in not just the nipple but also a portion of the surrounding areola. This ensures effective milk transfer and helps prevent nipple soreness or damage.
"My baby should breastfeed 5 to 10 minutes on each breast": This statement is not entirely accurate. It is important to understand that breastfeeding duration can vary among infants, and there is no fixed timeframe for how long a baby should breastfeed on each breast. Some infants
may nurse for shorter periods, while others may take longer. The focus should be on ensuring that the baby is effectively nursing and getting enough milk rather than adhering strictly to a specific time limit.
"I should keep my baby on a strict feeding schedule": This statement is incorrect. Breastfeeding on demand, also known as responsive feeding, is generally recommended for newborns.
Newborns should be fed whenever they show signs of hunger, such as rooting, sucking motions, or increased alertness. Strict feeding schedules can interfere with the baby's natural feeding cues and hinder milk supply establishment.
"I should not wake my baby during the night to breastfeed": This statement is not accurate, especially for a 5-day-old newborn. Newborns typically need frequent feeding, including during the night, to meet their nutritional needs and support proper growth and development. It is generally recommended to wake a sleeping newborn every 2-3 hours during the night to ensure adequate feeding and prevent excessive weight loss.
