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 A
Explanation
A. Engage the client in non-threatening conversations: Establishing a therapeutic nurse–client relationship through simple, supportive communication helps reduce isolation, builds trust, and may encourage the client to begin expressing thoughts and feelings.
B. Encourage the client's family to visit more often: Family involvement can be beneficial, but it may not be effective if the client is withdrawn. Increasing visits without first fostering a supportive environment could overwhelm or further isolate the client.
C. Encourage the client to participate in group activities: Group activities promote social interaction but may feel intimidating or threatening for someone who has been withdrawn for weeks. Gradual re-engagement beginning with one-on-one communication is more appropriate.
D. Schedule a daily conference with the social worker: Involving the social worker can be helpful for comprehensive care planning, but this does not directly address the immediate nursing priority of engaging the client therapeutically and reducing withdrawal.
Correct Answer is ["A","B","F","G"]
Explanation
Rationale for correct choices
• Heart rate 128 beats/minute, sinus tachycardia: Tachycardia signals early compensatory response to hypovolemia or hemorrhagic shock, common with abdominal trauma. Immediate attention is needed to prevent cardiovascular collapse.
• Blood pressure 90/79 mm Hg, pulse pressure less than 40 mm Hg: A narrow pulse pressure with low systolic BP suggests inadequate stroke volume and poor perfusion, consistent with ongoing internal bleeding.
• Capillary refill 6 seconds: Prolonged refill indicates impaired peripheral perfusion and circulatory compromise, reinforcing concerns of shock.
• No urine output: Absence of urine is a critical marker of inadequate renal perfusion and systemic hypoperfusion, reflecting worsening shock status.
Rationale for incorrect choices
• Temperature 96.9° F (36.1° C): Slightly low but not critical; mild hypothermia is common post-trauma and can be managed after stabilizing perfusion.
• Surgical dressing clean/dry with ecchymosis: Ecchymosis is expected after trauma and surgery, requiring monitoring but not immediate intervention.
• Heart sounds regular, lung sounds clear: No acute cardiopulmonary decompensation detected.
