A nurse is reinforcing teaching with a group of adult clients about health promotion and maintenance. The nurse should remind the clients that which of the following screenings should be performed beginning at age 50?

A. Leave the needle in place for 10 seconds after the injection: Leaving the needle in place for approximately 10 seconds after administering a subcutaneous injection helps ensure full delivery of the medication and reduces the chance of medication leakage at the injection site.

B. Use a 5-inch needle for the injection: A 5-inch needle is excessively long for subcutaneous injections and would likely penetrate muscle tissue, increasing the risk of injury or incorrect medication administration. Subcutaneous injections typically require a needle length between ⅜ and ⅝ inch.

C. Inject the medication using the Z-track technique: The Z-track technique is used for intramuscular injections to minimize medication leakage and reduce irritation. It is not appropriate for subcutaneous injections, which are administered into the fatty layer beneath the skin, not deep muscle tissue.

D. Insert the syringe at a 15° angle during injection: A 15° angle is used for intradermal injections. Subcutaneous injections should be administered at a 45° to 90° angle depending on the client’s body mass to ensure the medication is delivered into the subcutaneous tissue, not the dermis or muscle.

A. Dietary intake: The client ate toast at 0600 and experienced vomiting. Since general anesthesia is typically used for an appendectomy, recent food intake increases the risk of aspiration and should be reported immediately to the surgical team.

B. Pain level: The client reports increasing pain (now 8/10) with rebound tenderness. This may indicate worsening inflammation or risk of rupture, which requires reassessment and potentially expedited surgical intervention.

C. Blood pressure: The blood pressure of 124/80 mm Hg is within normal limits and does not require follow-up before surgery. It reflects stable hemodynamics.

D. Informed consent: The provider has already obtained informed consent and placed it in the medical record. No further follow-up is needed unless the client withdraws consent or shows signs of confusion.

E. Oxygen saturation: The client's oxygen saturation is 96% on room air, which is acceptable. There are no indications of respiratory compromise that require further intervention preoperatively.

F. Allergies: The client reports allergies to shellfish, latex, and penicillin. These pose serious risks during surgery (e.g., anaphylaxis to latex gloves or antibiotics) and must be addressed in the preoperative checklist to ensure appropriate substitutes are used.
