A nurse is reviewing the diagnostic tests used for HIV infection with a client. The nurse explains that nucleic acid tests (NAT) have the shortest window period after exposure, detecting HIV infection as early as:.

3-12 weeks.

2-6 weeks.

10-33 days.

6 months.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Nucleic acid tests (NAT) are highly sensitive tests that can detect HIV infection early, but the window period stated (3-12 weeks) is not accurate. NAT can detect HIV RNA as early as 9-11 days after exposure, but it may take up to 2-6 weeks for it to be reliably detected.

Choice B rationale:

This is the correct answer. Nucleic acid tests (NAT) can detect HIV infection as early as 2-6 weeks after exposure, making it the option with the shortest window period.

Choice C rationale:

This option is incorrect. NAT can detect HIV infection earlier than the time range stated (10-33 days)

Choice D rationale:

This option is incorrect. NAT can detect HIV infection much earlier than 6 months after exposure.

Correct Answer is A

Explanation

Choice A rationale:

This statement is correct. HIV-1 is more prevalent in West Africa and has a slower progression to AIDS compared to HIV-2.

Choice B rationale:

This statement is incorrect. HIV-2 is actually less virulent than HIV-1, and it is more commonly found in West Africa and certain parts of Asia.

Choice C rationale:

HIV-1 is divided into four groups (M, N, O, and P), each having several subtypes. HIV-2, on the other hand, is divided into nine subtypes (A to I)

Choice D rationale:

This statement is incorrect. The most common HIV-1 subtype worldwide is group M, specifically subtype C, which is predominant in sub-Saharan Africa and parts of Asia. The most common subtype in the US is subtype

A. Compare the patient's outcomes with the goals and expected outcomes. B. Modify the plan of care based on the patient's history and physical examination. C. Collect data about the patient's laboratory tests, psychosocial status, and educational needs. D. Provide counseling, feedback, and reinforcement for adherence to medication.

Correct Answer is A

Explanation

Compare the patient's outcomes with the goals and expected outcomes.

Choice A rationale:

The evaluation process involves comparing the patient's achieved outcomes with the established goals and expected outcomes of care. By doing this, the nurse can determine the effectiveness of the care provided and identify areas where adjustments may be necessary to improve patient outcomes.

Choice B rationale:

Modifying the plan of care based on the patient's history and physical examination is a part of the assessment and planning phases, not the evaluation phase. Evaluation focuses on measuring the success of the implemented care plan.

Choice C rationale:

Collecting data about the patient's laboratory tests, psychosocial status, and educational needs is crucial during the assessment phase to gather information for developing an appropriate care plan. While this information is valuable throughout the patient's care, it is not specific to the evaluation process.

Choice D rationale:

Providing counseling, feedback, and reinforcement for adherence to medication is an essential nursing intervention during the implementation phase. Although it supports patient compliance with treatment, it is not the primary focus of the evaluation process.
