A client who has tested positive for the human immunodeficiency virus (HIV) antibodies is admitted to the hospital with Pneumocystis Jiroveci Pneumonia (PCP) and a CD4+ T - Cell count of less than 200 cells/ ul. Based on the diagnostic criteria established by the Centers of Disease Control and Prevention (CDC), which statement by the nurse is correct?

A.

"The client meets the criteria for the chronic asymptomatic HIV infection phase."

B.

"The clients CD4+ T cell count is within normal range."

C.

"The client meets the criteria for the acute HIV infection phase."

D.

"The client has developed Acquired Immunodeficiency Syndrome (AIDS)."

Answer and Explanation

The Correct Answer is D

A. Chronic asymptomatic HIV infection refers to a phase with no opportunistic infections and higher CD4+ counts.

B. A CD4+ T cell count below 200 cells/μL is abnormal and diagnostic of AIDS, not within the normal range.

C. The acute HIV infection phase occurs shortly after exposure, characterized by flu-like symptoms and high viral load, not opportunistic infections.

D. The presence of Pneumocystis jiroveci pneumonia (an AIDS-defining illness) and a CD4+ T cell count below 200 cells/μL confirms a diagnosis of AIDS.

Correct Answer is C

Explanation

A. This is an underestimation due to a miscalculation of the dose rate.

B. This is an overestimation due to a miscalculation of the dose rate.

C. 1. Calculate the desired dose of dobutamine:

Desired dose (mcg/min) = Dose per kg (mcg/kg/min) x Weight (kg)

Desired dose (mcg/min) = 12 mcg/kg/min x 75 kg = 900 mcg/min

2. Convert mcg/min to mg/hr:

900 mcg/min x 60 min/hr = 54,000 mcg/hr

54,000 mcg/hr ÷ 1000 mcg/mg = 54 mg/hr

3. Calculate the concentration of dobutamine in the solution:

Concentration (mg/mL) = Total amount of dobutamine (mg) / Total volume (mL)

Concentration (mg/mL) = 1000 mg (1 g) / 250 mL = 4 mg/mL

4. Calculate the infusion rate (mL/hr):

Infusion rate (mL/hr) = Desired dose (mg/hr) / Concentration (mg/mL)

Infusion rate (mL/hr) = 54 mg/hr / 4 mg/mL = 13.5 mL/hr

5. Round to the nearest whole number:

Infusion rate (mL/hr) = 14 mL/hr

Therefore, the IV pump should be programmed for 14 mL/hr.

D. This is an overestimation due to a miscalculation of the dose rate.

Correct Answer is B

Explanation

A. A stable client with chronic angina is not in immediate danger, and the scheduled dose of nifedipine is not an urgent priority.

B. The client with unstable angina who has just undergone a heart catheterization with balloon angioplasty requires immediate assessment for complications such as bleeding, clot formation, or re-occlusion of the artery.

C. The 65-year-old post-MI client is stable, and while their anxiety is important to address, it is not an immediate concern compared to other clients.

D. The client post-coronary artery bypass with a potassium level of 4.2 mEq/L is stable and does not require urgent intervention.
