When a client needs oxygen therapy, what is the highest flow rate that oxygen can be delivered via nasal cannula?

Correct Answer: C

Rationale: The correct answer is 6 liters/minute. When a client requires oxygen therapy, the maximum flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Nasal cannula can effectively deliver oxygen up to 6 liters/minute. Flow rates exceeding 6 liters/minute may lead to drying of the nasal passages and discomfort for the client. Higher flow rates, like 8 liters/minute, should be administered using a mask to ensure sufficient oxygenation. Options A, B, and D are incorrect as they indicate flow rates that surpass the recommended maximum for nasal cannula delivery.

Correct Answer: C

Rationale: When fetal heart monitoring indicates fetal distress, interventions are aimed at improving oxygenation to the fetus. Increasing maternal fluids helps improve placental perfusion and oxygen delivery to the fetus. Administering oxygen also aids in increasing oxygen supply to the fetus. Turning the mother can help relieve pressure on the vena cava, optimizing blood flow to the placenta. Therefore, decreasing maternal fluids would not be performed as it can further compromise placental perfusion and fetal oxygenation, making it the exception. Decreasing maternal fluids could potentially exacerbate fetal distress by reducing oxygen delivery and nutrient supply to the fetus, which is contrary to the goal of managing fetal distress.

Correct Answer: C

Rationale: The correct answer is to assess the nail beds and the tissue surrounding the nails. This assessment is crucial to identify abnormal discoloration, lesions, paronychia, dryness, breaks in the skin, pressure areas, or any other unusual appearances. Choice A is incorrect as a full-body assessment is broader and not specific to nail and foot care. Choice B is incorrect as lab work is not directly related to nail and foot assessments. Choice D is incorrect as it focuses only on foot corns and calluses, neglecting other important aspects of nail and foot care.

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: D

Rationale: When delegating tasks, a nurse must consider the staff member's education and competency level. Noninvasive tasks like helping a client ambulate with a walker are usually suitable for nursing assistants. Suctioning a client and colostomy irrigation are invasive procedures that require a licensed nurse's skills. Assessing a client post-arteriogram for any complications or changes in condition also necessitates the expertise of a licensed nurse. Therefore, the most appropriate task to assign to a nursing assistant is assisting a client who needs frequent ambulation with a walker.
