A nurse is teaching a newly licensed nurse about the function of red bone marrow. Which of the following information should the nurse include?

Choice A reason: Verifying the dose with the provider ensures accuracy but is secondary to safety checks. Cefadroxil, a cephalosporin, can cause allergic reactions, and unverified doses may lead to errors, but checking allergies first prevents life-threatening anaphylaxis, prioritizing patient safety before confirming dosage accuracy.

Choice B reason: Shaking the cefadroxil suspension ensures uniform drug distribution, as particles settle in liquid formulations. This ensures accurate dosing but is not the first step, as administering to an allergic client risks severe immune responses, making allergy history verification the priority to ensure safety.

Choice C reason: Measuring with a calibrated syringe ensures precise dosing of cefadroxil, critical for therapeutic efficacy. However, this follows safety checks, as administering to an allergic client risks anaphylaxis, a rapid immune response involving histamine release, making allergy history verification the critical first step before measurement.

Choice D reason: Checking allergy history is the first step, as cefadroxil, a cephalosporin, may cause anaphylaxis in penicillin-allergic clients due to cross-reactivity. Allergic reactions involve immunoglobulin E-mediated histamine release, causing bronchospasm or hypotension. Verifying allergies prevents life-threatening reactions, ensuring safe administration before other steps like dosing or shaking.

Choice A reason: Advancing the cane 12 inches is not a universal rule, as the distance depends on the client’s stride length and balance needs. Typically, the cane advances 6-10 inches with the unaffected leg to provide optimal support. A fixed 12-inch instruction may lead to instability, making this an incorrect teaching statement.

Choice B reason: Holding the cane on the affected side reduces stability, as it fails to support the weaker leg during weight-bearing. The cane should be held on the unaffected side to provide a stable base, improving balance and reducing fall risk, making this an incorrect instruction for safe cane use.

Choice C reason: Keeping the cane at the same level as the affected leg when climbing stairs is incorrect. The cane moves with the unaffected leg first when ascending and with the affected leg when descending to ensure support. This vague instruction does not reflect proper stair-climbing technique, making it incorrect.

Choice D reason: Moving the unaffected leg first, alongside the cane, provides a stable base for the affected leg to follow, enhancing balance and reducing fall risk. This technique leverages the stronger leg’s strength and the cane’s support, making it the correct instruction for safe ambulation in clients with unilateral weakness.
