Which of the following options promotes the safe use of contact lenses?
Contact lens storage cases should be replaced every 3 months
Dispose of used contact solution daily
Remove lenses prior to using ocular medications
All of the above
The Correct Answer is D
A. Contact lens storage cases should be replaced every 3 months: Regular replacement of lens cases prevents microbial contamination, including bacteria and fungi, which can cause keratitis or other serious eye infections. Over time, biofilm can accumulate in cases even with routine cleaning, so replacing them quarterly is a key preventive measure.
B. Dispose of used contact solution daily: Reusing old or contaminated solution can introduce pathogens to the eye. Daily disposal ensures lenses are stored in fresh, sterile solution, reducing the risk of microbial keratitis, conjunctivitis, or corneal ulceration.
C. Remove lenses prior to using ocular medications: Administering eye drops over lenses can alter drug absorption, reduce efficacy, and increase risk of lens contamination. Removing lenses first ensures the medication reaches the cornea directly and prevents potential damage to the lenses.
D. All of the above: All listed measures collectively promote safe contact lens use by reducing infection risk, ensuring proper medication delivery, and maintaining lens hygiene. Each component is an essential part of evidence-based contact lens care practices.

Correct Answer is B
Explanation
When using medicated nasal sprays, patients should be instructed to blow their nose gently before administering the spray to clear the nasal passages. However, they should not blow their nose immediately after the dose, as this can remove the medication from the nasal mucosa and reduce its effectiveness. Proper technique involves tilting the head slightly forward, aiming the spray toward the lateral wall of the nostril (not the septum), and sniffing gently after administration to help distribute the medication. Counseling on correct use ensures optimal absorption and minimizes local irritation or bleeding.
Correct Answer is D
Explanation
A. Heat Treatment: While local heat can help relax muscles and reduce mild pain, it is not a systemic analgesic and may be inappropriate if there is broken skin or risk of infection. Heat could exacerbate local irritation or bacterial colonization at the site of cuts and scrapes.
B. Ibuprofen: Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) effective for pain and inflammation. However, VS has impaired renal function, and NSAIDs inhibit prostaglandin synthesis in the kidneys, which can reduce renal perfusion and worsen renal injury. Using ibuprofen could be nephrotoxic in this patient.
C. Naproxen: Similar to ibuprofen, naproxen is an NSAID with analgesic and anti-inflammatory properties. It also carries a high risk of nephrotoxicity in patients with pre-existing renal impairment, making it an unsafe first-line choice for VS.
D. Acetaminophen: Acetaminophen provides effective analgesia for mild musculoskeletal pain without significant impact on renal function. Since VS has impaired renal function and only mild pain without inflammation, acetaminophen is the safest systemic option, minimizing the risk of further kidney injury while addressing discomfort.
