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 ["A","B","D"]
Explanation
A. The fingerstick blood glucose level of 55 mg/dL at 1130 indicates hypoglycemia, which requires immediate attention to prevent further complications such as loss of consciousness or severe symptoms.
B. The client's report of shakiness, hunger, and cool, diaphoretic skin are signs of hypoglycemia, especially given the low blood glucose level. This requires prompt intervention to manage the blood glucose level.
C. The temperature of 37.8 °C (100 °F) is slightly elevated but does not require immediate follow-up unless there are other symptoms of infection or significant changes.
D. The elevated heart rate of 118/min could indicate an underlying issue such as dehydration, hypoglycemia, or infection. It requires further evaluation in the context of other findings.
E. The SpO2 of 95% on room air is within an acceptable range and does not require immediate follow-up unless there are other signs of respiratory distress or worsening condition.
F. The HbA1c of 8.01% reflects long-term glucose control but is not an immediate concern for follow-up in the acute setting. It is important for overall management but not an urgent issue for this particular scenario.
Correct Answer is D
Explanation
A. Vasopressin does not typically increase the client's heart rate; its primary effect is on the kidneys and urine output.
B. Vasopressin generally increases blood pressure by promoting vasoconstriction, not decreases it.
C. Vasopressin will increase, not decrease, urine specific gravity by reducing urine output and concentrating the urine.
D. Vasopressin acts to decrease urine output by increasing water reabsorption in the kidneys, which helps manage diabetes insipidus.
