A) "My heart rate may increase":
Digoxin is primarily used to slow the heart rate, not increase it. One of its actions is to increase the force of contraction of the heart while slowing the conduction through the atrioventricular (AV) node, which typically leads to a decreased heart rate. An increase in heart rate would be an unusual side effect and might indicate digoxin toxicity or another underlying issue.

B) "My vision may get blurred":
A common side effect of digoxin toxicity is visual disturbances, which may include blurred vision, yellow-green halos, or other color vision abnormalities. These symptoms are often associated with elevated digoxin levels in the blood and are a hallmark sign of toxicity.

C) "I may have constipation after taking this medication":
Constipation is not a typical side effect of digoxin. While some medications may cause constipation, this is not a primary or common side effect of digoxin. If constipation occurs, it may be due to other factors, such as diet, other medications, or a comorbid condition.

D) "My abdomen may hurt after taking this medication":
Although abdominal discomfort can be a side effect of many medications, it is not a primary or typical side effect of digoxin. If the patient experiences abdominal pain, it could be related to digoxin toxicity, especially if accompanied by other symptoms like nausea, vomiting, or diarrhea.

A) 6 Units Regular Insulin sub-cut:
According to the sliding scale, a blood glucose level of 164 mg/dL would not fall within the range requiring 6 units of insulin. The 6-unit dose is for blood glucose levels between 301-490 mg/dL. Since the client's reading of 164 mg/dL is lower than 181 mg/dL, this dosage is not applicable.

B) 2 Units Regular Insulin sub-cut:
This is also incorrect. The 2-unit dose is prescribed for blood glucose levels between 181-240 mg/dL. Since the client's reading is 164 mg/dL, it falls below this range, so 2 units is not appropriate.

C) 0.5 Units Regular insulin sub-cut:
This is not correct because there is no provision in the sliding scale for administering 0.5 units of insulin. The scale provides dosing for specific ranges and does not include fractional doses. Additionally, the blood glucose reading of 164 mg/dL does not require any insulin according to the prescribed sliding scale.

D) No coverage:
According to the sliding scale, a blood glucose level of 164 mg/dL falls within the 0-180 mg/dL range, which specifies no coverage or insulin administration. The sliding scale clearly indicates that no insulin is needed when the blood glucose level is within this range.
