A nurse is preparing discharge information for a client who has type 2 diabetes mellitus. Which of the following information resources should the nurse provide to the client?

Rationale for Correct Choices:

• A change in mood: Isotretinoin can cause psychiatric effects such as depression, mood swings, and suicidal ideation. These symptoms may appear suddenly and progress rapidly without warning. Immediate reporting is necessary to ensure patient safety and initiate intervention.
• Visual disturbances: Isotretinoin may cause night blindness, blurred vision, or other changes in visual acuity. These effects can be irreversible if not addressed promptly by an ophthalmologic evaluation. Sudden onset visual changes require immediate discontinuation and assessment.

Rationale for Incorrect Choices:

• Nausea: This is a mild, nonspecific gastrointestinal symptom that may occur with many oral medications. It is not considered a hallmark of isotretinoin toxicity unless severe or persistent. Supportive measures are usually sufficient unless other symptoms emerge.
• The development of dry eyes: This occurs due to isotretinoin’s suppression of sebaceous and meibomian gland activity. It is a common, expected effect that can be relieved with lubricating eye drops. Urgent evaluation is not required unless accompanied by vision changes.
• Dry mouth: This is a frequent mucocutaneous effect related to reduced salivary gland activity during isotretinoin therapy. It does not indicate a dangerous reaction and is usually managed with hydration and sugar-free lozenges. Medical review is only needed if severe.
• Photosensitivity: Isotretinoin increases skin sensitivity to sunlight due to thinning of the epidermis. While uncomfortable, it is a predictable effect that can be prevented with sunscreen and protective clothing. It does not require stopping treatment unless severe burns occur.
• Dry skin and lips: This is the most common side effect, resulting from reduced sebaceous gland activity. It is usually managed with moisturizers and lip balm throughout therapy. It is not a sign of toxicity and rarely requires dose adjustment.

Rationale:

B. Place the child in a sitting position: Positioning the child upright or with the head slightly tilted back promotes comfort, stability, and proper visualization of the conjunctival sac for accurate drop placement.

D. Pull the lower eyelid downward: This creates a conjunctival pocket that holds the medication and allows it to spread evenly over the eye surface without spilling.

C. Instill the drops of medication: Instillation should occur after exposing the conjunctival sac to ensure the medication reaches the target area. The dropper should not touch the eye to prevent contamination.

A. Apply pressure to the lacrimal punctum: This step is performed last to prevent systemic absorption of the medication by blocking the nasolacrimal duct. Holding gentle pressure for about 1 minute helps maximize the local effect of the drops.
