A nurse is teaching a class about administering IV fluids to treat dehydration. Which of the following findings should the nurse include in the teaching as an indicator of effective treatment of dehydration?

Lisinopril is an angiotensin-converting enzyme (ACE) inhibitorthat lowers blood pressure by preventing the synthesis of angiotensin II. A significant secondary effect of ACE inhibition is the reduction of aldosterone secretion, which leads to the retention of potassium by the kidneys. This pharmacological action poses a severe risk of hyperkalemia, necessitating the avoidance of supplemental potassium sources during therapy.

Rationale:

A.Levothyroxine is a synthetic thyroid hormone that does not have a direct pharmacological contraindication with ACE inhibitors like lisinopril. While the nurse should always monitor for general drug interactions, there is no specific mechanism where lisinopril and levothyroxine interfere with each other's safety or efficacy. Patients with both hypertension and hypothyroidism can safely take these medications concurrently.

B.Metformin is a biguanide used for the management of type 2 diabetes and is not contraindicated for use with lisinopril. ACE inhibitors are often the preferred antihypertensive for diabetic patients because they provide renal protection against diabetic nephropathy. The combination is considered clinically beneficial as long as the nurse monitors the patient's renal function and glucose levels regularly.

C.Potassium chloride is contraindicated for concurrent use with lisinopril because both medications contribute to elevated serum potassium levels. ACE inhibitors decrease aldosterone, which normally facilitates potassium excretion; adding a potassium supplement can lead to life-threatening hyperkalemia. This electrolyte imbalance can cause fatal cardiac arrhythmias, making it essential to clarify this prescription with the provider immediately.

D.Acetaminophen is a non-opioid analgesic and antipyretic that is generally safe to use for patients taking lisinopril for hypertension. Unlike non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen does not typically interfere with the blood pressure-lowering effects of ACE inhibitors or impair renal blood flow. It remains a safe choice for mild pain management in this patient population.

A medication error is an adverse eventthat necessitates immediate clinical and administrative action to ensure patient safety. The primary goal following an error is to assess the client for physiological instabilityand implement corrective treatments. Transparent communicationwith the healthcare team is essential for mitigating harm and documenting the event for future quality improvement initiatives.

Rationale:

A.The nursing supervisor should be notified as part of the facility's internal administrative process, but this is not the most immediate priority. While the supervisor oversees the unit's safety protocols, they cannot provide the medical orders necessary to treat a potential adverse reaction. Administrative notification should follow the clinical notification of the primary healthcare provider to ensure the patient's immediate health.

B.Agency administration is typically notified through the formal filing of an incident report once the patient is stable and immediate care has been coordinated. The administration uses this data for risk management and system-wide improvements rather than direct clinical intervention. Therefore, reporting to this department first would inappropriately delay the necessary medical assessment of the affected client.

C.The client's provider must be notified first so they can evaluate the clinical impact of the error and prescribe any necessary antidotes or monitoring. Immediate medical assessment is the highest priority to ensure the patient does not suffer from toxic effects or therapeutic failure. The provider is responsible for determining the next steps in the client's medical management plan.
