Which patient would benefit from the use of lubricant eye ointment?
A patient with chronic viral conjunctivitis
A stroke patient whose right eye does not close fully
A patient with an eye infection after swimming in a pond
A patient who has extended-wear contact lenses in place
The Correct Answer is B
Choice A reason: This is an incorrect choice because a patient with chronic viral conjunctivitis would not benefit from the use of lubricant eye ointment. Conjunctivitis is an inflammation of the conjunctiva, which is the thin membrane that covers the white part of the eye and the inner surface of the eyelid. Viral conjunctivitis is caused by a virus, such as adenovirus or herpes simplex virus, and it can cause redness, itching, burning, tearing, or discharge in the eye. Lubricant eye ointment is a thick, greasy substance that can moisturize and protect the eye, but it can also trap the virus and worsen the infection. The patient with viral conjunctivitis should use artificial tears or saline drops instead, and avoid sharing towels, cosmetics, or eye drops with others.
Choice B reason: This is the correct choice because a stroke patient whose right eye does not close fully would benefit from the use of lubricant eye ointment. A stroke is a sudden interruption of blood flow to the brain, which can cause damage to the brain cells and affect various functions, such as movement, sensation, speech, or vision. A stroke patient whose right eye does not close fully may have facial paralysis or weakness on the right side of the face, which can impair the ability to blink or close the eye. This can cause dryness, irritation, or injury to the eye, especially at night. Lubricant eye ointment can help to keep the eye moist and prevent corneal ulcers or infections. The patient may also need to wear an eye patch or tape the eye shut during sleep.
Choice C reason: This is an incorrect choice because a patient with an eye infection after swimming in a pond would not benefit from the use of lubricant eye ointment. An eye infection is an inflammation or infection of the eye or its structures, such as the cornea, the iris, or the eyelid. Swimming in a pond can expose the eye to various microorganisms, such as bacteria, fungi, or parasites, that can cause eye infections. Some examples are Acanthamoeba keratitis, which is a rare but serious infection of the cornea caused by a parasite, or Pseudomonas aeruginosa, which is a common cause of bacterial conjunctivitis. Lubricant eye ointment is not effective against these microorganisms, and it can also interfere with the penetration of antibiotic or antifungal eye drops. The patient with an eye infection after swimming in a pond should seek medical attention and use the prescribed eye drops as directed.
Choice D reason: This is an incorrect choice because a patient who has extended-wear contact lenses in place would not benefit from the use of lubricant eye ointment. Extended-wear contact lenses are soft lenses that can be worn continuously for up to 30 days and nights, without the need to remove them for cleaning or disinfection. However, extended-wear contact lenses can increase the risk of eye infections, such as bacterial or fungal keratitis, which can cause severe pain, redness, blurred vision, or sensitivity to light. Lubricant eye ointment is not compatible with contact lenses, and it can damage the lens material or cause deposits or cloudiness on the lens. The patient who has extended-wear contact lenses in place should follow the instructions of the eye care provider and remove the lenses immediately if any signs of infection or irritation occur.

Correct Answer is D
Explanation
Choice A reason: This is incorrect. Wiping up the liquid with paper towels and gloves can spread the mercury droplets and increase the risk of exposure. Mercury can also penetrate through nitrile gloves and cause skin irritation.
Choice B reason: This is incorrect. Disinfecting the area with chlorine bleach can create toxic vapours that can harm the respiratory system. Chlorine bleach is not effective in removing mercury from the surface.
Choice C reason: This is incorrect. Contacting the housekeeping staff to mop up the liquid can delay the proper clean-up and disposal of mercury. Mopping can also disperse the mercury droplets and contaminate the mop and the water.
Choice D reason: This is correct. Consulting the agency’s materials safety data sheets (MSDS) is the priority action of the nurse. MSDS provide information on the hazards, precautions, and procedures for handling and disposing of mercury. The nurse should follow the MSDS guidelines and use the appropriate equipment and methods to clean up the spill.
Correct Answer is C
Explanation
Choice A reason: This is incorrect. The PCA will not give additional pain medication whenever the button is pushed. The PCA is programmed to deliver a specific dose of pain medication at a specific interval. If the button is pushed before the interval is over, the PCA will not release any medication. This is to prevent overdose and side effects.
Choice B reason: This is incorrect. The PCA will not deliver medication through the IV until the pain is all gone. The PCA is designed to provide pain relief, not pain elimination. The PCA has a limit on how much medication it can deliver in a certain period of time. The patient may still have some pain even after using the PCA.
Choice C reason: This is correct. You or a designated family member are the only one who gets to push the PCA button-nobody else may do so. The PCA is intended to give the patient control over their pain management. The patient should push the button when they feel pain, not when someone else thinks they need it. Allowing others to push the button can lead to under- or over-medication, which can be harmful.
Choice D reason: This is incorrect. Wait until the pain becomes severe before pushing the PCA button is not a good instruction. The PCA is more effective when the patient pushes the button before the pain becomes too intense. Waiting too long can make the pain harder to control and require more medication. The patient should use the PCA as needed to keep the pain at a tolerable level.
