A nurse is reinforcing teaching with a client who is planning to complete a living will. Which of the following statements by the client indicates an understanding of the teaching?

A. The WBC count was not provided in the nurse’s notes or diagnostic section. Without any indication of infection or abnormal lab values, there is no basis to report WBC.

B. Although the pain level is mild (2/10), it may be contributing to anxiety, increased heart rate (110/min), and elevated BP (158/96 mm Hg). Report in context as part of a comprehensive assessment. Also, confirming that the pain is not worsening or atypical in nature is essential preoperatively.

C. The abdomen is soft, rounded, non-distended, with no tenderness, and active bowel sounds in all four quadrants — all normal postoperative readiness findings for abdominal surgery.

D. Knowing the blood type is routine pre-op procedure and is not an abnormal or urgent finding that needs immediate reporting. It is only relevant if transfusion is anticipated, which is not suggested here.

E. The client is requesting further details about the risks and benefits of surgery, which raises a legal and ethical concern about informed consent. The provider must ensure the client fully understands the procedure, otherwise surgery cannot proceed.

F. This is significantly elevated compared to baseline (126/74). Pre-op hypertension can increase surgical and anesthesia risk and should be evaluated further. It may be due to anxiety, pain, or another condition.

G. Platelet count values were not given in the scenario. Without abnormal lab results or bleeding concerns, there is no indication to report this.

H. This is lower than the previous baseline (97%). An SpO₂ < 94% on room air can signal underlying respiratory issues, atelectasis, sedation effects, or cardiac dysfunction, all of which should be addressed preoperatively.

I. The client ate breakfast at 0730 before a scheduled procedure, violating NPO (nothing by mouth) protocol. This significantly increases the risk of aspiration under anesthesia and must be reported immediately. The surgery may need to be rescheduled.

J. Capillary refill < 2 seconds is normal, indicating adequate peripheral perfusion. No issues with circulation are noted, so there's no reason to notify the provider.

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.
