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 C
Explanation
A. Notify the unit manager that an emergency court order is needed to allow surgery: Obtaining a court order can take significant time and is not feasible in a life-threatening emergency. Delaying surgery could result in serious harm or death.
B. Continue to provide life support until a thorough search for a guardian is completed: While life support stabilizes the client, delaying definitive treatment when immediate surgery is required may worsen outcomes. Emergency protocols allow treatment without consent in life-threatening situations.
C. Carry on with surgical preparation of the client without a signed informed consent: In emergencies where the client is unresponsive and immediate surgery is necessary to preserve life, healthcare providers can proceed without consent under the principle of implied consent. This ensures prompt, potentially life-saving intervention.
D. Ask the client's friend to sign the informed consent since the client is unresponsive: A friend does not have legal authority to provide consent unless formally designated as a healthcare proxy. Relying on the friend could delay urgent care and is not legally valid.
Correct Answer is {"dropdown-group-1":"B","dropdown-group-2":"A"}
Explanation
Rationale for correct choices:
• Respirations: Morphine is an opioid analgesic that can depress the respiratory center in the brainstem, leading to slowed breathing and hypoventilation. Monitoring respirations after administration is critical to detect early signs of opioid-induced respiratory depression.
• Ice application to the shoulder: Applying ice reduces swelling, pain, and inflammation by causing vasoconstriction and limiting fluid accumulation at the injury site. For an acute humeral fracture with significant swelling and bruising, cold therapy is the appropriate intervention.
Rationale for incorrect choices:
• Nausea: While morphine can cause nausea and vomiting as side effects, they are not the most life-threatening concerns compared to respiratory depression. Monitoring nausea is appropriate but not the priority when evaluating opioid safety.
• Blood pressure: Morphine can cause hypotension, but this effect is less common and typically secondary to respiratory depression and vasodilation. Continuous monitoring of blood pressure is helpful, but respiratory monitoring takes priority in detecting opioid complications.
• Early active range of motion: Active movement of the injured arm is not recommended immediately after a displaced humeral fracture, as it can worsen displacement and interfere with healing. Immobilization and stabilization are required before introducing range-of-motion exercises.
• Heat application to the shoulder: Heat increases blood flow to tissues, which can worsen swelling and bleeding in the acute phase of injury. Applying heat too soon after a fracture increases the risk of complications rather than reducing them.
