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 D
Explanation
Given:
Ordered dose of Heparin: 9 units/kg/hr
Patient weight: 76 kg
Concentration of Heparin: 50 units/mL
Step 1: Calculate the total dose of Heparin:
Total dose (units/hr) = Ordered dose (units/kg/hr) x Patient weight (kg)
Total dose (units/hr) = 9 units/kg/hr x 76 kg
Total dose (units/hr) = 684 units/hr
Step 2: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Total dose (units/hr) / Concentration (units/mL)
Infusion rate (mL/hr) = 684 units/hr / 50 units/mL
Infusion rate (mL/hr) = 13.68 mL/hr
Step 3: Round to the nearest tenth:
Infusion rate (mL/hr) ≈ 13.7 mL/hr
Correct Answer is B
Explanation
A) Cough:
Cough is more commonly associated with angiotensin-converting enzyme (ACE) inhibitors, such as enalapril or lisinopril, rather than with beta blockers. ACE inhibitors can cause a persistent dry cough due to the accumulation of bradykinin. Beta blockers do not generally have a direct effect on causing cough, so this is not a typical side effect of beta blockers.
B) Hypotension:
Hypotension (low blood pressure) is a common and well-documented side effect of beta blockers. Beta blockers, such as metoprolol, atenolol, and propranolol, work by blocking beta-adrenergic receptors, leading to a reduction in heart rate and the force of heart contractions, which can lower blood pressure. In patients with already low blood pressure or those receiving other antihypertensive medications, this effect may be more pronounced and could lead to symptomatic hypotension, such as dizziness or lightheadedness.
C) Anxiety:
Anxiety is not a common side effect of beta blockers. In fact, beta blockers are sometimes prescribed to manage symptoms of anxiety, particularly for physical symptoms like palpitations and tremors. However, anxiety may worsen in some individuals due to other factors, such as the psychological impact of dealing with heart disease, but this is not a typical side effect of beta blockers.
D) Elevated heart rate:
Beta blockers work to decrease heart rate by blocking the effects of adrenaline (epinephrine) on beta-adrenergic receptors. This leads to a slower heart rate and reduced workload on the heart. Therefore, elevated heart rate is not a common side effect of beta blockers. In fact, if the heart rate becomes too low (bradycardia), this can be a concerning side effect, but it is the opposite of an elevated heart rate.
