The dose is 8mg. The supply is 4mg/ml. How many ml does the nurse give?

A. Evaluation:
Evaluation involves the assessment of a patient's response to nursing interventions and the effectiveness of the care plan. In this scenario, the nurse is not evaluating the patient's response to previous interventions but is rather in the process of conducting a new assessment.

B. Assessment:
This statement is correct. The nurse is in the assessment phase of the nursing process. She is collecting data by checking the patient's record, performing a physical examination (digital rectal exam), and noting the patient's complaint and signs of constipation (no bowel movement for three days, hard stool). Assessment is the first step of the nursing process and involves data collection to identify health problems and needs.

C. Nursing Diagnosis:
Nursing diagnosis involves analyzing the data collected during the assessment to identify actual or potential health problems. The nurse has not reached the stage of formulating a nursing diagnosis in this scenario; she is still gathering data.

D. Implementation:
Implementation is the phase of the nursing process where nursing interventions are carried out based on the nursing care plan. The nurse is not implementing interventions yet but is still in the process of data collection.

Here's the breakdown of each step:

Assessment: This is the first step in the nursing process. It involves gathering information about the patient's health status. Assessment can include collecting data through interviews, physical examinations, and reviewing medical records.

Nursing Diagnosis: After assessing the patient, the nurse analyzes the data to identify nursing diagnoses or issues. Nursing diagnoses are clinical judgments about individual, family, or community responses to actual or potential health problems or life processes.

Planning: Based on the nursing diagnosis, the nurse develops a plan of care. This plan outlines the goals and outcomes the nurse hopes to achieve. It also includes interventions, which are the actions the nurse will take to address the nursing diagnoses.

Implementation: During this phase, the nurse puts the plan into action. This can include administering medications, providing treatments, educating patients, and other nursing interventions.

Evaluation: Evaluation is the final step. The nurse assesses the patient's response to nursing interventions and determines if the goals and outcomes have been met. If the goals have not been met, the nurse may need to revise the plan of care.
