Correct Answer: B

Rationale: The ANA Position Statement on Assisted Suicide stresses the importance of identifying patient and family concerns and fears. This reflects the nurse's responsibility to provide holistic care and support to patients and their families who may be struggling with end-of-life decisions. By identifying concerns and fears, the nurse can address these issues through compassionate communication, education, and appropriate interventions. This proactive approach aligns with the ethical principles of beneficence and nonmaleficence in nursing practice.

Correct Answer: D

Rationale: Black or tarry stools can be caused by certain medications and supplements, such as iron supplements. Since the fecal occult test is negative, it indicates that bleeding is not occurring. Therefore, in this situation, it is important to consider factors that can affect the color of stool, including iron supplementation. Addressing this question can help determine the cause of the black stool and provide appropriate guidance or reassurance to the patient. This response shows a comprehensive understanding of potential causes and demonstrates a thoughtful approach in addressing the patient's concern.

Correct Answer: C

Rationale: The nurse's best response is option C - "AIDS isn't transmitted by casual contact." This response is accurate and provides the necessary information to address the friend's concern. It is important to educate the friend that HIV/AIDS is not transmitted through casual contact such as visiting a patient in the hospital. By stating this fact clearly, the nurse can help alleviate any unfounded fears or misconceptions the friend may have about contracting HIV while visiting the patient. This response promotes understanding and helps reduce stigma associated with HIV/AIDS, while also emphasizing the importance of accurate information in preventing the spread of the virus.

Correct Answer: B

Rationale: The signs of magnesium toxicity that the nurse should monitor for in a patient with severe preeclampsia on IV magnesium sulfate include an altered sensorium (confusion, lethargy, slurred speech) and a respiratory rate of less than 12 breaths per minute. Altered sensorium is a common symptom of magnesium toxicity, reflecting the drug's central nervous system depressant effects. A decreased respiratory rate can indicate respiratory depression, a potentially serious complication of magnesium toxicity. Monitoring for these signs is crucial to promptly identifying and managing magnesium toxicity in patients on magnesium sulfate therapy. Signs such as cool, clammy skin and a pulse oximeter reading of 95% would not be indicative of magnesium toxicity.

Correct Answer: D

Rationale: Chronic urinary retention can lead to an elevated blood urea nitrogen (BUN) level due to impaired kidney function. When urine is not effectively eliminated from the body, waste products, including urea, accumulate in the bloodstream. This can result in an increase in BUN levels, indicating potential kidney dysfunction in the setting of chronic urinary retention. Hypertension (Choice A), peripheral edema (Choice B), and tachycardia and other dysrhythmias (Choice C) are not specifically associated with chronic urinary retention but may be related to other conditions or comorbidities.
