A nurse is providing teaching to a client who is to receive a series of allergy tests. The nurse should instruct the client to avoid which of the following medications for up to 4 weeks before the procedure?

A.

Acetaminophen

B.

Pseudoephedrine hydrochloride

C.

Diphenhydramine

D.

Albutero

Answer and Explanation

The Correct Answer is C

A. Acetaminophen: Acetaminophen is not an antihistamine and does not typically interfere with allergy testing. It can be safely continued before the procedure. 
B. Pseudoephedrine hydrochloride: Pseudoephedrine is a decongestant and does not directly interfere with the results of allergy testing. It is not necessary to avoid pseudoephedrine for this purpose. 
C. Diphenhydramine: Diphenhydramine is an antihistamine and should be avoided for up to 4 weeks before allergy testing to ensure accurate results. Other antihistamines should also be discontinued for the same duration. 
D. Albuterol: Albuterol is a bronchodilator and does not interfere with the results of allergy testing. It can be continued before the procedure.

Correct Answer is ["60"]

Explanation

1.Convert the available lidocaine concentration to mg/mL:
2 g of lidocaine = 2000 mg
2000 mg ÷ 500 mL = 4 mg/mL

2. Determine the mL/min required to deliver 4 mg/min:
4 mg/min ÷ 4 mg/mL = 1 mL/min

3. Convert mL/min to mL/hr:
1 mL/min × 60 minutes = 60 mL/hr

Correct Answer is D

Explanation

A. Oxygen saturation 96%:
Oxygen saturation at 96% is within the normal range and may not be directly influenced by the infusion of albumin. Albumin administration is more related to improving intravascular volume and blood pressure.
B. PaCO2 30 mm Hg:
The partial pressure of carbon dioxide (PaCO2) is a measure of respiratory status. Albumin infusion is not directly associated with changes in PaCO2.
C. Decrease in protein:
Albumin is a protein, and its infusion would not lead to a decrease in protein levels. In fact, albumin administration increases the oncotic pressure in the intravascular space, helping to retain fluid and improve blood volume.
D. Increase in BP:
This is the correct answer. Albumin is a colloid solution that increases oncotic pressure in the bloodstream. By increasing oncotic pressure, albumin helps to draw fluid from the interstitial space into the vascular space, thereby increasing blood volume. This can contribute to an increase in blood pressure, which is a desired effect in the management of shock.
