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

To calculate the number of 40mg capsules needed for a 2-grain dose, you need to convert grains to milligrams since the supply is given in milligrams (mg).

1 grain is approximately equal to 64.8 milligrams.

Now, let's calculate:

2 grains * 64.8 mg/grain = 129.6 mg

So, the nurse would give 129.6 milligrams of the medication. Since the supply is in 40mg capsules, you'll need to divide the total dose by the amount in each capsule to determine the number of capsules needed:

129.6 mg / 40 mg/capsule ≈ 3.24

Since you can't give a fraction of a capsule, the nurse would give 4 capsules to achieve a dose of approximately 129.6 milligrams.

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.
