A surgical nurse is handing off a client to the post-anesthesia care unit (PACU) nurse after the client underwent a laparoscopic procedure. Which section of the SBAR communication tool is the nurse using when describing the client's comorbidities of diabetes, hypertension, and related history?

A.Cephalexin is a first-generation cephalosporin, a class of antibiotics that shares a similar beta-lactam ring structure with penicillins. Due to this structural similarity, there is a risk of cross-sensitivity in patients with a known penicillin allergy, which could result in an anaphylactic reaction. The nurse must clarify this prescription to ensure the client's safety and determine if an alternative class of antibiotics, such as a macrolide, is more appropriate.

B.A sulfa allergy involves a hypersensitivity to sulfonamide-containing medications, which are chemically distinct from cephalosporins. There is no known cross-reactivity between sulfa drugs and cephalexin, so this finding would not typically require a clarification of the antibiotic prescription. The nurse should still document the allergy, but it does not pose a direct contraindication to the administration of a beta-lactam antibiotic like cephalexin.

C.A latex allergy is a hypersensitivity to the proteins found in natural rubber latex and is irrelevant to the pharmacological profile of cephalexin. While a latex allergy is critical for the surgical team to know for equipment and glove selection, it does not affect the choice of antibiotic therapy. The nurse must ensure a latex-free environment for the client, but the administration of cephalexin remains safe from an immunological standpoint.

D.Shellfish allergies are typically related to a hypersensitivity to iodine or specific proteins in crustaceans and do not have any cross-reactivity with cephalosporin antibiotics. This allergy is most relevant when a client is receiving iodine-based contrast media for diagnostic imaging rather than preoperative antibiotic prophylaxis. The nurse should document the allergy as part of the standard health history, but it does not necessitate a change in the prescribed antibiotic.

A.Aspiration for blood return is contraindicated when administering subcutaneous heparin because it increases the risk of local tissue trauma and hematoma formation. Pulling back on the plunger can create a vacuum that ruptures small capillaries in the adipose tissue. This mechanical stress leads to unnecessary bruising and may interfere with the predictable absorption of the anticoagulant.

B.Massaging the injection site after heparin administration is strictly avoided as it can cause significant ecchymosis and tissue irritation. Physical manipulation of the site accelerates the spread of the medication into damaged capillaries, potentially leading to a localized hemorrhage. The nurse should avoid any friction or pressure that could disrupt the integrity of the subcutaneous vascular network.

C.The Z-track method is a specific technique reserved for deep intramuscular injections to prevent medication leakage into subcutaneous tissues. It is not used for subcutaneous administration of heparin, which is specifically designed for absorption within the fatty layer. Utilizing this method for heparin would be an incorrect application of parenteral technique and would not mitigate the risk of bruising.

D.Correct administration involves cleansing the skin, inserting the needle into the subcutaneous layer, and injecting the medication without aspiration or subsequent massage. Applying gentle pressure after needle withdrawal helps prevent the leakage of blood or medication from the puncture site. This technique minimizes the risk of hematoma and ensures the anticoagulant is delivered safely into the intended tissue plane.
