The six rights of medication administration is:

a) Encouraging increased fluid intake is not always appropriate for a patient on a thiazide diuretic, as these drugs promote fluid loss. Excess fluid intake may not be beneficial unless there are signs of dehydration.

b) Increasing activity and exercise can be beneficial for overall health, but the priority is ensuring safety due to the risk of orthostatic hypotension and falls.

c) Initiating a fall risk protocol is crucial because thiazide diuretics can cause hypotension, dizziness, and electrolyte imbalances, all of which increase the risk of falls, particularly in older adults.

d) Providing a low potassium diet is inappropriate, as thiazide diuretics can lead to hypokalemia (low potassium levels), so monitoring and possibly increasing potassium intake may be necessary.

A. Assessment is the first phase of the nursing process, during which the nurse gathers relevant patient data, such as allergies and lab values, to ensure safe medication administration. This step helps identify potential risks and contraindications.

B. Evaluation occurs after the medication has been administered and involves assessing the patient's response to the drug. In this case, the nurse is reviewing information before administration, making evaluation an incorrect choice.

C. Implementation refers to carrying out the nursing interventions, such as actually administering the medication. Since the nurse is still reviewing data, this step has not yet been reached.

D. Planning involves setting goals and determining appropriate interventions, but it does not include the direct collection of patient data. Reviewing lab values and allergies falls under the assessment phase.
