A client has a Sliding Scale for Insulin dosages sub-cut. The order is for Humulin Regular Insulin U-100 q6h as follows:
0-180 mg/dL No Coverage
181-240 mg/dL 2 units sub-cut 241-300 mg/dL 4 units sub-cut
301-490 mg/dL 6 units sub-cut
Greater than 400 mg/dL administer 8 units sub-cut and repeat finger stick in 2 hr, call MD/Provider At 3:30 PM. the client's finger stick is 164 mg/dL How much coverage should the patient receive?
6 Units Regular Insulin sub-cut
2 Units Regular Insulin sub-cut
0.5 Units Regular insulin sub-cut
No coverage
The Correct Answer is D
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.

Correct Answer is C
Explanation
A) Flushing of the face:
Flushing is a common and usually harmless side effect of nitroglycerin, caused by its vasodilation properties. It often resolves quickly and is not typically a cause for concern. While it can be uncomfortable, it is not a sign of a serious problem that would require immediate medical attention.
B) Dizziness upon standing:
Dizziness upon standing (orthostatic hypotension) is a known side effect of nitroglycerin due to its blood pressure-lowering effects. It typically occurs when the patient rises too quickly from a sitting or lying position. While it can be uncomfortable and may cause the patient to feel lightheaded, it is usually not an emergency and can often be managed by rising slowly. If dizziness persists or is severe, the healthcare provider should be notified, but it is not an immediate emergency.
C) Persistent chest pain that lasts longer than 15 minutes:
Chest pain lasting longer than 15 minutes could indicate a myocardial infarction (heart attack) rather than stable angina, even if nitroglycerin has been administered. Chest pain that is not relieved by nitroglycerin or persists for more than a few minutes is an emergency situation and should be reported immediately to the healthcare provider or emergency services.
D) Mild headache:
Headache is a common and benign side effect of nitroglycerin, caused by its vasodilation effect. It is usually mild and transient and does not require immediate medical attention. In most cases, the headache improves over time or with the use of over-the-counter pain relievers, and it is not a reason to contact the healthcare provider unless it becomes severe or persistent.
Correct Answer is D
Explanation
Given:
Volume of fluid: 100 mL
Infusion time: 30 minutes
Drop factor: 60 gtt/mL
Formula:
Flow rate (gtt/min) = (Volume (mL) / Time (min)) x Drop factor (gtt/mL)
Step 1: Calculate the infusion rate in mL/min:
Infusion rate (mL/min) = Volume (mL) / Time (min)
Infusion rate (mL/min) = 100 mL / 30 min
Infusion rate (mL/min) = 3.33 mL/min
Step 2: Calculate the flow rate in gtt/min:
Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)
Flow rate (gtt/min) = 3.33 mL/min x 60 gtt/mL
Flow rate (gtt/min) = 200 gtt/min
