The nurse is caring for a client who is having chest pain. The healthcare provider prescribes an infusion of nitroglycerin. The initial dose is 12 mcg/min. The nitroglycerin is dispensed at a concentration of 100 mg/ 250 mL. How many mL/hr will the nurse set the infusion pump? (Round rate to the nearest tenth. Only enter numbers and decimals. Do not enter any letters in your answer.)
The Correct Answer is ["1.8"]
Infusion rate (mL/hr) = Desired dose (units/hr) / Concentration of nitroglycerin (units/mL)
First, calculate the concentration of nitroglycerin in the IV bag:
- 100 mg / 250 mL = 0.4 mg/mL
Next, convert the desired dose from mcg/min to mg/hr:
- 12 mcg/min 60 min/hr = 720 mcg/hr = 0.72 mg/hr
Finally, plug the values into the formula:
- Infusion rate = 0.72 mg/hr / 0.4 mg/mL = 1.8 mL/hr

Correct Answer is B
Explanation
A. Drying the sclera with a cotton swab prior to administering eye drops is not recommended and could introduce fibers or cause irritation. Proper eye drop administration does not require drying the sclera.
B. Administering the medications 5 minutes apart is correct because it allows each medication to be absorbed properly, preventing the second drop from washing out the first. This timing helps ensure that both medications are effective.
C. Touching the tip of the dropper to the sclera is incorrect and can introduce contaminants, leading to infection. Eye drops should be administered without the dropper touching the eye to maintain sterility.
D. Holding pressure on the conjunctival sac for 2 minutes is excessive. The recommended practice is to gently press on the nasolacrimal duct for 1-2 minutes after administration to prevent systemic absorption, especially with medications like timolol.
Correct Answer is C
Explanation
A. An HbA1c level of 7.5% indicates suboptimal long-term glucose control. The target for many diabetic patients is usually below 7%, but it may not require immediate action compared to more acute indicators.
B. A 2-hour post-prandial blood glucose level of 122 mg/dL is slightly above the normal range but not significantly high. This result alone is not as indicative of inadequate control as other values.
C. A random blood glucose level of 300 mg/dL is significantly elevated and indicates poor glucose control. This value is much higher than the normal range and suggests a need for further teaching and adjustment of diabetes management.
D. A fasting blood glucose level of 48 mg/dL is low and could indicate hypoglycemia rather than inadequate control. This level requires immediate attention but does not reflect poor long-term diabetes management.
