A patient is ordered an ophthalmic solution 1 drop tid daily to both eyes. The nurse understands that the eye drops will be administered:
one drop to both eyes four times a day
one drop to both eyes as needed
one drop to both eyes three times a day
one drop to both eyes two times a day
The Correct Answer is C
A. one drop to both eyes four times a day: Administering the drops four times daily exceeds the prescribed frequency. Overmedication can increase the risk of local irritation, systemic absorption, or toxicity, and does not align with the provider’s intended dosing schedule. Accurate adherence to the order is essential for safe and effective therapy.
B. one drop to both eyes as needed: "As needed" (PRN) dosing allows for patient- or symptom-driven administration, which differs from a scheduled prescription. The order specifies a fixed schedule (tid), so administering PRN would not ensure therapeutic effectiveness or consistency of drug levels in the eyes.
C. one drop to both eyes three times a day: "Tid" stands for three times a day, and administering one drop to each eye at this frequency follows the provider’s instructions. Proper timing ensures consistent therapeutic drug levels, maximizes efficacy, and minimizes complications or missed doses.
D. one drop to both eyes two times a day: Administering the drops twice daily would underdose the patient, potentially reducing the treatment’s effectiveness. It does not meet the prescribed "tid" schedule, which is necessary for achieving the intended clinical outcome.

Correct Answer is B
Explanation
A. Sacral area: The sacral area is commonly used to assess for pressure injuries, especially in bedridden patients, but it is not ideal for assessing skin turgor. In older adults, the skin over the sacrum may be affected by chronic edema, thinning, or immobility, which can give misleading results when assessing elasticity.
B. Sternum: The sternum is the preferred site for assessing skin turgor in older adults because the skin here is less affected by age-related laxity and subcutaneous fat loss compared with extremities. Pinching the skin over the sternum provides a more accurate indication of hydration status and elasticity without interference from normal aging changes.
C. Back of the hand: In older adults, the skin on the hands tends to be thin, wrinkled, and less elastic due to aging, which can lead to false-positive signs of dehydration when assessing turgor. This makes it an unreliable site for hydration assessment.
D. Axillary region: The axilla is warm and moist, which can make it difficult to accurately assess skin turgor. Additionally, skin in this area is not typically tested for elasticity or hydration, as it is more prone to variability and environmental influence.
Correct Answer is B
Explanation
Calculation:
- Identify the given time in 24-hour format
Given time: 2100
- Convert to 12-hour format
Since 2100 is greater than 1200, subtract 1200 to convert to PM time: 2100 − 1200 = 900
- Add the colon and AM/PM notation
= 9:00 pm
