Correct Answer: B

Rationale: The nurse should prioritize educating the patient on the importance of keeping appointments for desensitization procedures. Immunotherapy involves gradually increasing exposure to allergens to build tolerance and reduce allergic reactions. Missing desensitization appointments can lead to interruptions in treatment and potentially decrease the effectiveness of the therapy. It is crucial for the patient to adhere to the scheduled appointments as prescribed by the healthcare provider to ensure the success of the immunotherapy treatment.

Correct Answer: A

Rationale: Nausea and vomiting are common adverse effects of chemotherapy. Administering an antiemetic helps to prevent or reduce these symptoms in patients undergoing chemotherapy. By managing nausea and vomiting, the patient's overall well-being and quality of life during treatment can be improved. Therefore, providing an antiemetic medication is essential in combating these adverse effects and promoting patient comfort and compliance with treatment.

Correct Answer: A

Rationale: Challenging communication situations in nursing care typically involve patients who exhibit behaviors that make communication difficult or complex. In the given options, a child who is developmentally delayed (Option A) and an older-adult patient who is demanding (Option B) are examples of patients who may have challenging communication issues.

Correct Answer: B

Rationale: Smoking cessation most directly addresses the leading cause of cancer deaths in North America, which is lung cancer. Tobacco use, particularly cigarette smoking, is the primary cause of lung cancer. By helping individuals quit smoking, the public health nurse is targeting the main risk factor for lung cancer and therefore addressing the root cause of the issue. This intervention has the potential to have a significant impact on reducing cancer-related deaths in the community. Monthly self-breast exams, annual colonoscopies, and monthly testicular exams are important for detecting breast, colon, and testicular cancers respectively, but they do not directly address the leading cause of cancer deaths in North America.

Correct Answer: A

Rationale: Gay, lesbian, and bisexual young people have a significantly increased risk for depression, anxiety, suicide attempts, and substance use disorders. In particular, bisexual youth are at a higher risk than their straight peers for experiencing mental health issues and suicide attempts that require medical attention. Studies have shown that young bisexuals are four times more likely than their straight counterparts to make suicide attempts that necessitate medical intervention. Therefore, it is crucial for the nurse to closely monitor this population group for signs of suicidal behavior and provide the necessary support and interventions to prevent such tragedies.
