Nursing Elites

1. A CD4+ lymphocyte count is performed on a client infected with HIV. The results of the test indicate a CD4+ count of 450 cells/L. The nurse interprets this test result as indicating:

• A. Improvement in the client
• B. The need for antiretroviral therapy
• C. The need to discontinue antiretroviral therapy
• D. An effective response to the treatment for HIV

Correct answer: B

Rationale: A CD4+ count of 450 cells/L is below the normal range (500-1600 cells/mcL), indicating a decline in immune function in the client. Antiretroviral therapy is recommended when the CD4+ count falls below 500 cells/mcL or below 25%, or when the client displays symptoms of HIV. Therefore, the interpretation of this test result suggests that the client requires antiretroviral therapy to manage the HIV infection. Choices A, C, and D are incorrect because a CD4+ count of 450 cells/L does not signify improvement, discontinuation of therapy, or an effective response to treatment for HIV.

2. What is the most common cause of coronary artery disease?

• A. Atherosclerosis.
• B. Hyperlipidemia.
• C. Diabetes.
• D. Smoking.

Correct answer: A

Rationale: The correct answer is Atherosclerosis. It is the primary cause of coronary artery disease, as it involves the buildup of plaque in the arteries, restricting blood flow to the heart. Hyperlipidemia (choice B) contributes to atherosclerosis by increasing cholesterol levels in the blood but is not the direct cause of coronary artery disease. Diabetes (choice C) can accelerate atherosclerosis due to high blood sugar levels, but it is not the most common cause. Smoking (choice D) is a significant risk factor for developing coronary artery disease but is not the primary cause.

3. A healthcare professional is reviewing the results of serum laboratory studies of a client with suspected hepatitis. Which increased parameter is interpreted as the most specific indicator of this disease?

• A. Hemoglobin
• B. Serum bilirubin
• C. Blood urea nitrogen (BUN)
• D. Erythrocyte sedimentation rate (ESR)

Correct answer: B

Rationale: Serum bilirubin is the most specific indicator of hepatitis as it reflects liver dysfunction. Hemoglobin, blood urea nitrogen (BUN), and erythrocyte sedimentation rate (ESR) are not specific to hepatitis. Hemoglobin measures the oxygen-carrying capacity of red blood cells, BUN evaluates kidney function, and ESR is a nonspecific marker of inflammation or infection.

4. The nurse instructs the unlicensed nursing personnel (UAP) on how to provide oral hygiene for clients who cannot perform this task for themselves. Which of the following techniques should the nurse tell the UAP to incorporate into the client's daily care?

• A. Assess the oral cavity each time mouth care is given and record observations.
• B. Use a soft toothbrush to brush the client's teeth after each meal.
• C. Swab the client's tongue, gums, and lips with a soft foam applicator every 2 hours.
• D. Rinse the client's mouth with mouthwash several times a day.

Correct answer: B

Rationale: The correct technique to incorporate into the client's daily care for oral hygiene is to use a soft toothbrush to brush the client's teeth after each meal. This helps in maintaining oral hygiene for clients who cannot perform this task themselves. Choice A is incorrect because assessing the oral cavity each time mouth care is given is important but not the technique to incorporate into daily care. Choice C is incorrect as swabbing the tongue, gums, and lips every 2 hours may not be necessary for daily care. Choice D is incorrect as rinsing the client's mouth with mouthwash several times a day may not be suitable for all clients and is not a standard recommendation for daily oral care.

5. Which of the following is the most important nursing action when administering a blood transfusion?

• A. Monitoring the patient's blood pressure.
• B. Monitoring the patient's temperature.
• C. Monitoring the patient's heart rate.
• D. Monitoring the patient's oxygen saturation.

Correct answer: A

Rationale: The most important nursing action when administering a blood transfusion is monitoring the patient's blood pressure. This is crucial because monitoring blood pressure allows for the prompt identification of any signs of adverse transfusion reactions, such as transfusion reactions or fluid overload. Immediate intervention can be initiated if any complications arise. While monitoring temperature, heart rate, and oxygen saturation are also essential aspects of patient care, they are not as critical as blood pressure monitoring during a blood transfusion. Therefore, the correct answer is to monitor the patient's blood pressure.
