Correct Answer: D

Rationale: The correct answer is D: All of the above. Addiction is influenced by various factors, including low self-esteem, family history of addiction, and specific personality traits. Low self-esteem can lead individuals to seek solace in substances, a family history of addiction can increase the likelihood of developing addictive behaviors due to genetic and environmental factors, and certain personality disorders may contribute to addictive tendencies. Therefore, all the factors listed in choices A, B, and C can play a role in the development of addictive disorders. Choices A, B, and C are incorrect because addictive disorders are multifactorial, and it is essential to consider a combination of influences rather than isolating a single factor.

Correct Answer: A

Rationale: The correct answer is A: Blood pressure. Sildenafil, a medication for erectile dysfunction, can cause changes in blood pressure. The nurse should monitor for hypotension as a potential side effect. Monitoring heart rate (choice B) is not a priority when administering sildenafil unless there are pre-existing heart conditions. Temperature (choice C) and respiratory rate (choice D) are typically not directly affected by sildenafil administration, making them less relevant for monitoring in this case.

Correct Answer: B

Rationale: Hypotension is a critical sign of anaphylaxis. During anaphylaxis, there is a widespread vasodilation leading to a drop in blood pressure, which manifests as hypotension. This can be accompanied by other symptoms such as swelling, difficulty breathing, hives, and itching. Bradycardia (choice A) is not typically associated with anaphylaxis; instead, tachycardia is more common due to the body's response to the allergic reaction. Increased appetite (choice C) is unrelated to anaphylaxis, as individuals experiencing anaphylaxis often feel unwell and may have nausea or vomiting. Decreased respiratory rate (choice D) is also not a typical finding in anaphylaxis; instead, respiratory distress and wheezing are more commonly observed.

Correct Answer: D

Rationale: The correct statement that the nurse should include in the teaching is option D: 'Hospice care continues to help families with grief after a death occurs.' Hospice care not only focuses on providing comfort care for terminal patients but also offers bereavement support to families after the patient's death. Choices A, B, and C are incorrect. Option A is incorrect because hospice care does not provide rehabilitation for the patient; its focus is on comfort and quality of life. Option B is incorrect because hospice care does not aim to extend life but rather to provide quality end-of-life care. Option C is incorrect because hospice care does not transition patients to nursing care; it provides care focused on comfort and symptom management in the patient's preferred setting.

Correct Answer: C

Rationale: Corrected Rationale: Serum phenytoin levels should be regularly monitored to prevent toxicity because the therapeutic range is narrow. Monitoring blood pressure (choice A), complete blood count (choice B), and liver function tests (choice D) are not directly related to preventing phenytoin toxicity.
