Correct Answer: D

Rationale: While urinalysis can provide valuable information about a person's health status and can be part of a clinical assessment, it is not typically considered a common screening test for specific diseases or conditions. The other options listed - Pap smears for cervical cancer screening, cholesterol levels for heart disease screening, and PSA levels for prostate cancer screening - are all commonly used screening tests aimed at early detection of specific diseases. Urinalysis is more commonly used as part of a broader health assessment or diagnostic evaluation rather than a dedicated screening tool for a specific condition.

Correct Answer: A

Rationale: The bioethical issue described in option A revolves around the concept of advance directives. Advance directives are legal documents that outline a person's wishes regarding medical treatment in the event that they are unable to communicate those wishes themselves. In this scenario, the issue pertains to the withholding of food and treatment based on a written advance directive that was made before the patient suffered permanent brain damage. This raises important ethical considerations about respecting a patient's autonomy and adhering to their previously expressed wishes, even in difficult circumstances. The decision to withhold treatment in such a situation is a complex bioethical issue that needs to be handled carefully while balancing the principles of autonomy and beneficence.

Correct Answer: B

Rationale: When a patient describes their pain as a 5 on the pain assessment scale, it indicates severe pain and the need for a strong pain medication. Morphine Sulphate is a potent opioid analgesic that is commonly used to manage severe pain, such as in cases where the pain is rated as 5. Meperidine HCl (Demerol) is another opioid analgesic, but it is not as commonly used due to its side effect profile and potential for toxicity. Fentanyl (Duragesic) is also a potent opioid analgesic that can be used for severe pain, but morphine is often preferred in this situation. Acetaminophen (Tylenol) is a milder pain reliever and is not typically sufficient for pain described at a level of 5 on the pain scale.

Correct Answer: A

Rationale: Opsonization refers to the process by which antibodies bind to the surface of pathogens, marking them for destruction by phagocytes or complement proteins. This coating of antibodies enhances the ability of the immune system to recognize and eliminate the pathogens effectively. Phagocytes (such as macrophages and neutrophils) are better able to engulf and digest pathogens that have been opsonized, as the antibodies attached to the pathogen surface signal to the phagocytes that they are foreign invaders. This process is crucial in the body's immune response to infections and helps in clearing pathogens from the system.

Correct Answer: B

Rationale: The right to refuse treatment is a fundamental patient right. In this case, the physician ordering medications for the client to take at home without the client's input or agreement could possibly violate the client's right to refuse treatment. It is important for patients to have the autonomy to make decisions regarding their own treatment, especially when they are still weak and symptomatic. Patients should have the opportunity to discuss their treatment plan with their healthcare provider and express any concerns or preferences they may have.
