Rationale: Step-by-step rationale: 1. CD4+ cells are a type of white blood cell crucial for immune function. 2. HIV targets and destroys CD4+ cells, leading to immune system damage. 3. Measuring CD4+ levels helps determine the extent of this damage. 4. Therefore, the correct answer is B. Summary: A: Presence of opportunistic infections - CD4+ levels indirectly affect susceptibility, but not measured for this purpose. C: Level of the viral load - Measured separately from CD4+ levels. D: Resistance to antigens - CD4+ levels do not directly indicate resistance.

Correct Answer: D

Rationale: The correct answer is D because the nurse's signature indicates that they verified the patient's signature on the consent form. This step ensures that the patient has signed the document willingly. Choice A is incorrect because the nurse doesn't obtain informed consent, that's the responsibility of the physician. Choice B is incorrect because nurses do not provide informed consent. Choice C is incorrect as the nurse witnessing the signature doesn't imply they answered all surgical procedure questions.

Correct Answer: B

Rationale: The correct answer is B: Have a mammogram annually. Mammograms are recommended by the American Cancer Society for breast cancer screening in women as they are effective in detecting early signs of breast cancer. Mammograms have been shown to reduce mortality rates from breast cancer. Annual mammograms are crucial for early detection and treatment. A: Performing breast self-examination annually is not recommended as a standalone screening method as it has not been shown to significantly reduce mortality rates. C: Having a normal receptor assay annually is not a standard screening test for breast cancer recommended by the American Cancer Society. D: Having a physician conduct a clinical examination every 2 years is not as effective as annual mammograms for detecting early signs of breast cancer.

Correct Answer: B

Rationale: The correct answer is B: Safety of the immediate environment. This is crucial for the client's well-being and can impact their health. The nurse should assess for hazards like loose rugs, clutter, or slippery floors. This ensures a safe living environment for the client. The other choices (A, C, D) are not directly related to the client's immediate safety or well-being. The number of rooms in the house (A) is not as important as ensuring the safety of the environment. The frequency of home visits (C) can be planned later based on the initial assessment. The friendliness of the client and family (D) is important for building rapport but does not address the immediate safety concerns of the client.

Correct Answer: B

Rationale: The correct answer is B: Blurring of vision. This is typically the first symptom of a cataract because the clouding of the lens causes light to scatter, leading to blurred vision. Dry eyes (A) and eye pain (C) are not typically associated with cataracts. Loss of peripheral vision (D) is more commonly seen in conditions like glaucoma. In summary, blurring of vision is the hallmark symptom of cataracts due to lens clouding, distinguishing it from other eye conditions.
