Correct Answer: C

Rationale: Before administering medications through an NG tube, the nurse must first check the placement of the tube to prevent aspiration. This is done by aspirating gastric contents and measuring the pH. Checking the client's apical pulse is unrelated to NG tube medication administration. Checking when the last feeding was given is important but not a priority before administering medications. Checking when the last medications were given is also not directly related to ensuring the safe administration of medications through an NG tube. Ensuring the correct placement of the tube is crucial to prevent complications such as pulmonary aspiration.

Correct Answer: D

Rationale: The correct answer is 'Hispanic.' Hispanic individuals in the United States are at a higher risk for pesticide-related injuries due to their representation among migrant workers in agricultural settings. This exposure to pesticides in their work environments increases their risk compared to other ethnic groups. Choice A, 'Native American,' although indigenous populations may face environmental health disparities, the higher risk in this context is among Hispanic individuals. Choice B, 'Asian-Pacific,' and Choice C, 'Norwegian,' do not have the same level of exposure to pesticides as Hispanic migrant workers, making them less susceptible to pesticide-related injuries.

Correct Answer: B

Rationale: The most assertive response in dealing with this conflict is the one that is direct and conveys a clear message in a positive manner. The nurse should assertively communicate her unavailability for overtime without being confrontational. Option A, "I'm not working overtime today," is too blunt and may come across as rude. Option C, "You know how I hate to work overtime," is not assertive but rather passive-aggressive. Option D, "I will if you need me, but I am not happy about this," is a passive-aggressive response as it implies compliance while expressing discontent. Option B, "I have plans after work and will not be able to work overtime," is the most appropriate response as it clearly states the nurse's unavailability without unnecessary aggression.

Correct Answer: D

Rationale: The correct answer is that the DNR order requires frequent review as specified by state or agency policy. If the client's condition changes, the DNR order may need to be changed. For this reason, DNR orders require frequent review as specified by state or agency policy. A DNR order may be changed at any time and does not remain in effect for the duration of the client's hospitalization. The client's request regarding DNR status is the priority. Choice A is incorrect because healthcare providers, not just immediate family members, may change the DNR order based on the client's condition. Choice B is incorrect as DNR orders can be changed if the client's condition warrants it, not remaining unchanged. Choice C is incorrect as DNR orders are not fixed for the duration of hospitalization, they can be modified based on the client's needs.

Correct Answer: A

Rationale: The least appropriate assignment for a nursing assistant would be assisting a client with dysphagia in eating. This task requires specialized skills and knowledge to prevent complications such as choking and aspiration. Ambulating a client with Parkinson's disease, providing hygiene to a client with dementia, and assisting a client with an above-the-knee amputation in showering are tasks that a nursing assistant can safely perform without significant risk of complications. Assisting a client with dysphagia in eating involves higher risks and requires specific training, making it the least appropriate choice for a nursing assistant.
