Nitroglycerin may come in pill form and is taken

Correct Answer: C

Rationale: The correct answer is C: Under the tongue. Nitroglycerin in pill form is typically taken sublingually, which means under the tongue, to quickly enter the bloodstream and provide rapid relief for chest pain associated with angina. By placing it under the tongue, it can be absorbed directly into the bloodstream through the mucous membranes, allowing for faster onset of action. A: Nitroglycerin is not typically taken as injections, as the pill form is more common for oral administration. B: Nitroglycerin is not administered intravenously as it can cause rapid and severe drops in blood pressure. D: Rectal administration of nitroglycerin is not common practice and is not the recommended route for its administration due to slower absorption compared to sublingual administration.

Correct Answer: A

Rationale: The correct answer is A because applying products between the toes can lead to moisture buildup, increasing the risk of fungal infections in diabetic patients. This guideline helps prevent complications like athlete's foot. Turning socks over at the tops (B) and using all-nylon socks (C) are not specific to foot care for diabetic patients. Cutting toenails carefully (D) is important but not directly related to diabetic foot care.

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 to the human herpesvirus 8 (HHV-8), which tends to affect individuals with weakened immune systems. Kaposi's sarcoma presents as skin lesions and can also affect internal organs. Pneumocystis pneumonia (A) is an opportunistic infection common in AIDS patients, not a cancer. Prostate cancer (B) and liver cancer (C) are not specifically associated with AIDS.

Correct Answer: C

Rationale: The correct answer is C because clots in the drainage tubing can obstruct fluid drainage, leading to potential complications such as pneumothorax or hemothorax. Clots need to be reported as they can impede the effectiveness of the chest tube. Choices A, B, and D are incorrect because they do not directly relate to a critical issue with chest tubes like clots do. A - The drainage system being below chest level can affect drainage but is not as critical as clots. B - The resident's nap schedule is not relevant to chest tube care. D - The orientation of drainage containers being upright does not pose a direct problem unless it impacts drainage flow.

Correct Answer: D

Rationale: The correct answer is D: Perform a procedure if it is within his scope of practice. This is the correct choice because performing procedures within one's scope of practice ensures that the nursing assistant has the necessary training, skills, and legal authorization to safely carry out the task. It aligns with professional standards and guidelines, promoting patient safety and quality care. A, B, and C are incorrect choices because they do not consider the importance of following legal and ethical boundaries in healthcare. Choice A suggests performing procedures without training, which can lead to harm to the patient. Choice B implies a trial-and-error approach, which is unsafe and unprofessional. Choice C disregards the importance of job descriptions and legal limitations, potentially risking patient safety and violating regulations.
