A. "Your provider has prescribed antibiotic therapy to be administered intravenously every 6 hours.": This response directly explains the medical reason for the saline lock, linking it to the client’s prescribed therapy. It provides clarity and reinforces that the intervention is necessary for safe and effective treatment.

B. "Clients over the age of 65 must have a saline lock according to facility policy.": Age alone is not a valid reason for IV access. Using such an explanation could reduce trust between the nurse and the client.

C. "It is quicker to administer medications intravenously in the hospital.": While IV administration can be faster, this response is vague and does not address why this particular client specifically requires a saline lock. It lacks individualized rationale.

D. "We administer all medications intravenously to clients in this unit.": Not all medications are given intravenously. Providing this explanation would confuse the client and reflect poor communication of actual care needs.

• The therapeutic effect of ACE inhibitors is unrelated to their mechanism of action: This is inaccurate because the therapeutic effects, including vasodilation and lowered blood pressure, are directly linked to ACE inhibition.
• Understanding the mechanism of action helps anticipate potential side effects of ACE inhibitors: Knowing that ACE inhibitors reduce angiotensin II and aldosterone helps the nurse anticipate side effects such as hypotension, hyperkalemia, and persistent cough.
• ACE inhibitors work by inhibiting the angiotensin-converting enzyme, leading to vasodilation: This directly explains the mechanism, resulting in decreased blood pressure and reduced afterload, which are the therapeutic goals in hypertension and heart failure management.

• All medications within the ACE inhibitor class have identical therapeutic effects: While similar, individual ACE inhibitors differ in duration of action, metabolism, and dosing, so effects are not identical across the class.
