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.)

Answer and Explanation

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

Explanation

A. Levothyroxine is a thyroid hormone replacement used to treat hypothyroidism. Symptoms such as tremors, nervousness, and insomnia can indicate that the dose is too high, as these are signs of hyperthyroidism.
B. Weight loss is not a typical reason to notify the healthcare provider unless it is accompanied by other symptoms of hyperthyroidism. Monitoring for symptoms of excessive thyroid hormone can be more critical.
C. Levothyroxine does not typically require monitoring for an increased risk of bleeding. This medication primarily affects thyroid hormone levels and does not have a direct impact on blood clotting.
D. Levothyroxine increases, rather than decreases, thyroid hormone levels. It is used to replace or supplement thyroid hormone in the case of hypothyroidism, not to decrease thyroid hormone production.

A. Performing hand hygiene before, during, and after direct contact with the client B. Changing the client's bed linens each day C. Controlling the client's blood glucose level D. Placing the client in a room with positive-pressure airflow

Correct Answer is A

Explanation

A. Performing hand hygiene before, during, and after direct contact with the client is the most effective strategy for preventing the transmission of infections. Hand hygiene interrupts the transmission of pathogens and is a cornerstone of infection control practices.
B. Changing the client's bed linens each day is a standard practice for maintaining cleanliness but does not specifically prevent infection transmission. The primary goal of infection control is to reduce pathogen transmission rather than just maintaining general cleanliness.
C. Controlling the client's blood glucose level is important for overall health and wound healing but does not directly prevent infection transmission. It is not an infection control strategy.
D. Placing the client in a room with positive-pressure airflow is used to protect immunocompromised patients from infections by preventing outside air from entering the room. However, it is not appropriate for preventing the transmission of an infection from a client to others.
