A nurse is reinforcing teaching with a client with bacterial conjunctivitis of the right eye, and a prescription for an antibiotic ophthalmic ointment. Which of the following statements should the nurse make?
"Apply the ointment in a thin line into the conjunctival sac."
"Keep your eye open for 30 sec after instilling the ointment."
"Use a sterile glove and applicator to apply the antibiotic ointment."
"Always wipe from the outer to the inner canthus when wiping away secretions."
The Correct Answer is A
A) "Apply the ointment in a thin line into the conjunctival sac":
This instruction is correct for applying ophthalmic ointments. Placing the ointment in a thin line along the conjunctival sac ensures proper distribution and contact with the affected area.
B) "Keep your eye open for 30 sec after instilling the ointment":
Keeping the eye open for a brief period after instillation helps the ointment spread across the eye surface. This statement indicates understanding of the proper technique for applying ophthalmic ointments and does not require further instruction.
C) "Use a sterile glove and applicator to apply the antibiotic ointment":
Using a sterile glove and applicator ensures that the application is done in a sterile manner, reducing the risk of introducing further infection. This statement indicates a need for further instruction, as ophthalmic ointments are typically applied using clean hands or disposable, sterile applicators rather than sterile gloves.
D) "Always wipe from the outer to the inner canthus when wiping away secretions":
Wiping from the outer to the inner canthus helps prevent contamination of the unaffected eye. This statement demonstrates understanding of proper eye care techniques and does not require further instruction.

Correct Answer is C
Explanation
A) "Heparin enhances the effects of the warfarin.": This statement is incorrect. Heparin and warfarin work through different mechanisms. Heparin acts quickly by inhibiting clot formation through antithrombin, while warfarin acts slower by inhibiting vitamin K-dependent clotting factors. They do not directly enhance each other's effects.
B) "Both heparin and warfarin work together to dissolve the clots.": This is inaccurate. Neither heparin nor warfarin dissolve existing clots; they prevent new clots from forming and existing clots from growing. The body's natural processes will eventually dissolve the clot.
C) "Heparin will be continued until the warfarin reaches a therapeutic level!": This is correct. Heparin is used initially because it acts quickly. Warfarin takes several days to reach therapeutic levels. Overlapping the two ensures continuous anticoagulation until warfarin is effective.
D) "I will ask the charge nurse to call your provider and get an explanation.": While involving the provider for further explanation can be helpful, it does not directly answer the client’s question. Providing accurate information about the overlapping use of heparin and warfarin is more appropriate in this context.
Correct Answer is D
Explanation
A) "This medication prevents gastric acid secretion in the stomach":
Sucralfate does not affect gastric acid secretion. It works by forming a protective barrier over ulcers, adhering to the ulcer surface and shielding it from gastric acid and other digestive enzymes. This mechanism helps to promote healing of duodenal ulcers by providing a protective environment for the ulcer to heal without exposure to gastric acid.
B) "This medication kills the bacteria which cause ulcers":
Sucralfate does not possess antibacterial properties and does not target bacteria like Helicobacter pylori, which can cause ulcers. Its action is focused on providing a physical barrier to protect the ulcer from further damage.
C) "This medication neutralizes gastric acid after it is secreted":
Neutralizing gastric acid is the role of antacids, not sucralfate. Sucralfate acts by adhering to the ulcer site and forming a protective layer, which is distinct from the mechanism of neutralizing acid after secretion.
D) "This medication adheres to the ulcer and protects it from gastric acid":
Sucralfate forms a protective barrier over ulcers by adhering to the ulcer surface. This adherence helps to shield the ulcer from gastric acid and other digestive juices, promoting healing by creating an environment conducive to tissue repair.
