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","B","D"]

Explanation

A. Encourage the client to increase fluid intake: This is important to prevent dehydration, which can be a complication of influenza.
B. Wear a mask when caring for the client: Influenza is a highly contagious virus, and wearing a mask can help prevent the spread of infection.
C. Prepare to administer an antibiotic to the client: Antibiotics are not typically used to treat influenza, which is a viral infection. However, if a bacterial infection develops as a complication, antibiotics may be necessary.
D. Place the client in a private room: Isolating the client in a private room can help prevent the spread of influenza to other patients and healthcare workers.
E. Place the client on contact precautions: Influenza is primarily spread through respiratory droplets, so droplet precautions are appropriate. Contact precautions are not necessary for influenza.

A. Positive Western blot test B. CD4-T-cell count 505 cells/mm³ (nl. 500-1500 cells/mm³) C. Platelets 115,000/mm³ (nl. 140,000-400,000/mm³) D. White blood cell (WBC) count 800/mm³ (nl. 5000-10,000/mm³)

Correct Answer is D

Explanation

A. A positive Western blot test confirms the diagnosis of HIV, but it is not concerning once the diagnosis has been established.
B. A CD4-T-cell count of 505 cells/mm³ is low but not critically low. While it does indicate immunosuppression, it is not the most concerning value presented.
C. A platelet count of 115,000/mm³ is lower than normal and may indicate a risk for bleeding, but it is not as concerning as a critically low white blood cell count.
D. A WBC count of 800/mm³ is severely low and indicates a high risk for infection, which is particularly concerning in a client with HIV, as it suggests significant immunosuppression and vulnerability to opportunistic infections.
