Nitroglycerin may come in pill form and is taken

Correct Answer: C

Rationale: The correct answer is C: Under the tongue. Nitroglycerin pills are typically taken sublingually, or under the tongue, where they can be rapidly absorbed into the bloodstream to provide quick relief for angina symptoms. This route allows the medication to bypass the digestive system and liver metabolism, leading to faster onset of action. Explanation of other choices: A: Injections - Nitroglycerin is not typically administered as injections for angina relief. B: Intravenously - Intravenous administration is not a common route for nitroglycerin used in the treatment of angina. D: Rectally - Nitroglycerin is not typically given rectally for the treatment of angina.

Correct Answer: A

Rationale: The correct answer is A because applying products between the toes can lead to moisture accumulation, which increases the risk of fungal infections in diabetic individuals. It is crucial to maintain dryness in the foot area to prevent infections. Turning socks over at the tops (choice B) does not directly relate to foot care for diabetic residents. Using all-nylon socks (choice C) may not be suitable as they can trap moisture. Cutting toenails carefully (choice D) is important but does not address the specific guideline for foot care in diabetic individuals.

Correct Answer: D

Rationale: The correct answer is D: Kaposi's sarcoma. This type of cancer is commonly associated with AIDS due to its link with Human Herpesvirus 8 and weakened immune system. Kaposi's sarcoma presents as skin lesions or tumors in various organs. Choices A, B, and C are incorrect as Pneumocystis pneumonia is a common opportunistic infection in AIDS, prostate cancer and liver cancer are not specifically linked to AIDS.

Correct Answer: C

Rationale: The correct answer is C because clots in the drainage tubing can obstruct the flow of fluid, leading to complications like pneumothorax. It is crucial to report this issue promptly to prevent respiratory distress. A: Drainage system level does not directly affect the function of the chest tube. B: Resident's nap frequency is unrelated to chest tube care. D: Upright drainage containers are appropriate for gravity drainage.

Correct Answer: D

Rationale: Rationale for Correct Answer (D): A nursing assistant should only perform procedures that are within their scope of practice to ensure patient safety and quality care. Scope of practice defines the tasks and responsibilities that a healthcare provider is trained and authorized to perform, ensuring competence and expertise in those specific areas. By following their scope of practice, nursing assistants can prevent potential harm to patients and maintain professional standards. Summary of Incorrect Choices: A (Perform all procedures even if he has no training): This choice is incorrect as performing procedures without proper training can pose significant risks to patients and is unethical. B (Perform a procedure if he has forgotten how to do it): This choice is incorrect as relying on memory alone may lead to errors and jeopardize patient safety. C (Perform a procedure not in job description but knows how to do it): This choice is incorrect as job descriptions are based on scope of practice, and performing tasks outside of it can result in legal and ethical issues.
