Final answer:
The missing activity in the nursing process sequence 'assessing, _____________, planning, implementing, and evaluating' is 'diagnosing.' Nurses must diagnose to create effective care plans, including in specialized settings like dialysis treatments.
Step-by-step explanation:
The essential activities involved in the nursing process are assessing, diagnosing, planning, implementing, and evaluating. The correct answer to fill in the blank is 'a) Diagnosing.' Nurses work under the direct supervision of a registered nurse and must be skilled in evaluating patient needs and conditions. Correct diagnosis is crucial in this process, as it leads to the development of an appropriate care plan, guiding further actions such as planning and implementing prescribed care and treatments. Evaluating the outcomes of the implemented plan is essential to ensure patient well-being and to make necessary adjustments. A nurse involved in dialysis treatments would apply this process by assessing the patient's current condition, diagnosing any issues, planning and implementing the treatment, and then evaluating the patient's response to the treatment. For example, this may include taking and reporting vital signs and preparing solutions and equipment to ensure accurate and sterile procedures.
