Correct Answer: A

Rationale: Mottling of the lower limbs is a common physical sign seen in patients approaching death. This occurs when there is poor circulation leading to a bluish or purplish discoloration of the skin, particularly on the extremities. The appearance of mottling indicates that the body is no longer able to maintain adequate blood flow to the extremities, signaling that the patient is in the final stages of life. It is a significant finding that strongly suggests imminent death in patients with terminal illness, such as in this case of a patient with terminal lung cancer who is unconscious.

Correct Answer: B

Rationale: During the primary infection stage of HIV, the patient is newly infected with the virus. At this stage, the patient's immune system has not yet produced HIV-specific antibodies, making it difficult to detect HIV infection using standard antibody tests. Instead, the virus can be detected by testing for the presence of HIV RNA or p24 antigen. The primary infection stage is characterized by a high level of viral replication and rapid spread of the virus throughout the body. In this early stage, the patient may experience flu-like symptoms such as fever, sore throat, muscle aches, and swollen lymph nodes. The absence of HIV-specific antibodies means that the patient is highly infectious and can easily transmit the virus to others. As the infection progresses, the patient will eventually develop HIV-specific antibodies, which can be detected through antibody tests.

Correct Answer: B

Rationale: The Cowper glands, also known as bulbourethral glands, are a pair of small exocrine glands located below the prostate gland, within the posterior aspect of the male urethra. These glands are responsible for producing a clear, viscous fluid that helps lubricate the urethra, neutralize acidic urine remnants, and provide a conducive environment for sperm to survive in the urethra. Inflammation of the Cowper glands can result in conditions such as urethritis or other discomfort related to the male reproductive system.

Correct Answer: A

Rationale: Encouraging the patient to verbalize her questions and concerns is the best way to assess her specific educational, physical, or psychosocial needs during preoperative teaching for an incisional biopsy of a right breast mass. This approach allows the nurse to better understand the patient's knowledge level, fears, anxieties, and any misconceptions she may have related to the procedure. By actively listening to the patient's questions and concerns, the nurse can tailor the education provided to address specific areas of importance to the patient, ensuring she receives the information and support she needs to feel prepared and comfortable before the procedure. This approach promotes open communication, trust, and patient-centered care.

Correct Answer: A

Rationale: At present, the most reliable method for verification of placement of small-bore feeding tubes is x-ray examination. X-ray allows for direct visualization of the tube's placement within the gastrointestinal tract, ensuring it is correctly positioned in the stomach without any risk of inadvertent placement in the lungs, pharynx, or esophagus. This method provides a definitive confirmation of tube placement, which is crucial for patient safety during enteral feeding. While pH testing and aspiration of contents can be useful as supplementary methods, x-ray remains the gold standard for verifying tube placement due to its precision and accuracy. Auscultation, on the other hand, is no longer recommended as a reliable method for tube placement verification, as it may lead to misinterpretation of sounds and potential errors in placement assessment.
