A client diagnosed with glaucoma receives a new prescription for dorzolamide. Prior to administering the medication, the nurse should review the electronic medical record for which allergy?
lodine.
Latex.
Penicillin.
Sulfonamide.
The Correct Answer is D
A. Iodine: An iodine allergy is more relevant for clients receiving contrast media or iodine-based antiseptics, not dorzolamide. Dorzolamide is a carbonic anhydrase inhibitor, and its risk profile is not associated with iodine sensitivity.
B. Latex: Latex allergy is an important consideration in nursing care, particularly regarding equipment and supply use. However, dorzolamide as an ophthalmic preparation does not contain latex, so this allergy does not directly influence the safety of administering the drug.
C. Penicillin: Penicillin allergy is significant for antibiotics, but dorzolamide is not a beta-lactam or related medication. There is no cross-reactivity between penicillin and carbonic anhydrase inhibitors, making this allergy less concerning for this prescription.
D. Sulfonamide: Dorzolamide contains a sulfonamide component, and clients with a sulfonamide allergy are at risk for hypersensitivity reactions such as rash, conjunctivitis, or even systemic effects. Reviewing the medical record for a sulfonamide allergy is essential before administration to prevent serious complications.

Correct Answer is B
Explanation
A. Check the client's arm for a "Do Not Resuscitate" (DNR) bracelet: While verifying a DNR order is important, not all advance directives are represented by a bracelet. This action alone does not clarify the client’s wishes or the specifics of the living will.
B. Seek clarification of the type of advance directive the client has: Living wills and other advance directives vary in scope and specificity. Confirming the type of directive ensures that care aligns with the client’s legally documented wishes and guides future interventions appropriately.
C. Explain that living wills cannot be followed by emergency personnel: Emergency personnel can follow advance directives if they are clearly documented and accessible. Saying they cannot be followed is inaccurate and may create mistrust with the family.
D. Schedule a client and family conference to review the plan of care: A conference may be helpful later for education and care planning, but it does not address the immediate need to clarify the client’s specific directives after an emergency intervention.
Correct Answer is ["A","D","E","G","H"]
Explanation
A. Apply warm blankets: Warm blankets are a safe, noninvasive method to prevent further heat loss and support gradual rewarming in a client with hypothermia. They help increase comfort and core temperature.
B. Administer an antipyretic: Antipyretics lower fever caused by infection or inflammation. This client has hypothermia, not hyperthermia, so this action would worsen the condition rather than improve it.
C. Place ice packs around the client's head: Ice packs are used for hyperthermia management, not hypothermia. Applying them would further reduce core body temperature and increase the risk of complications.
D. Check the temperature of the humidified oxygen attached to the ventilator: Ensuring the oxygen is warmed and humidified prevents further heat loss through the respiratory tract, which is critical for a hypothermic intubated client.
E. Instill warm fluids in the nasogastric tube: Warmed enteral fluids can help gently increase core body temperature when administered via an NG tube, especially in prolonged hypothermia management.
F. Microwave a pack of gauze and distribute across the body: This method is unsafe because microwaving medical supplies is not a controlled or standardized rewarming method, posing a risk of burns or uneven heating.
G. Administer intravenous fluids with a rapid infuser: Warm IV fluids given rapidly restore circulating volume in trauma clients and also help increase core body temperature, addressing both shock and hypothermia.
H. Use a fluid warmer for intravenous fluids: Actively warming IV fluids before administration is a safe and effective method to prevent further heat loss and correct hypothermia in critically ill clients.
