A nurse is assessing a client's understanding of a surgical procedure prior to witnessing their signature on the informed consent form. The nurse determines that the client does not understand what the procedure will involve. Which of the following actions should the nurse take?

Choice A rationale:
High lipase is not a typical laboratory finding related to overusing prescribed diuretics and a sodium level of 127 mEq/L. Lipase is an enzyme involved in lipid digestion and is more relevant in assessing pancreatic function.
Choice B rationale:
High creatine kinase-MB (CK-MB) is not associated with overusing prescribed diuretics or hyponatremia (low sodium level). CK-MB is a specific marker for myocardial damage and is usually elevated in conditions like myocardial infarction.
Choice C rationale:
Low hemoglobin is not directly related to overusing prescribed diuretics and a sodium level of 127 mEq/L. Low hemoglobin may indicate anemia or other hematological issues but this is not a typical finding in this scenario.
Choice D rationale:
The correct answer is low urine specific gravity. Overusing diuretics can lead to excessive urination, causing the urine to become more dilute with lower specific gravity. A low urine specific gravity indicates decreased urine concentration and can be a sign of fluid and electrolyte imbalances, including hyponatremia.

Choice A rationale:

Administering morphine intermittent IV bolus every 2 hours is not a suitable intervention for reducing the risk of atelectasis. While pain management is important postoperatively, morphine can depress respiratory function and increase the risk of atelectasis.

Choice B rationale:

Turning the client from side to side every 4 hours is important for preventing pressure ulcers and promoting comfort, but it is not a specific intervention for reducing the risk of atelectasis.

Choice C rationale:

Providing nasotracheal suctioning for 15 to 20 seconds at a time is not a preventive measure for atelectasis. Suctioning may be necessary for airway clearance in certain situations, but it does not address the root cause of atelectasis.

Choice D rationale:

This is the correct choice. Instructing the client to hold the inhaled breath for 2 to 5 seconds with incentive spirometer use is an effective intervention to reduce the risk of atelectasis. Incentive spirometry helps to expand the lungs and improve ventilation, preventing atelectasis after surgery.
