The nurse encourages a client with an immunologic disorder to eat a nutritionally balanced diet to promote optimal immunologic function. Autoimmunity has been linked to excessive ingestion of:

Correct Answer: C

Rationale: The correct answer is C: Fat. Excessive ingestion of fat has been linked to autoimmunity due to its potential to trigger inflammation in the body, which can disrupt the immune system's balance and lead to autoimmune responses. High-fat diets have been associated with increased production of pro-inflammatory molecules, impacting immune function negatively. Protein (choice A) is essential for immune function, vitamin A (choice B) supports immune responses, and zinc (choice D) is crucial for immune system regulation. However, excessive intake of these nutrients typically does not directly lead to autoimmunity like excessive fat consumption does.

Correct Answer: B

Rationale: The correct answer is B because ordinal petition in the family is not a recognized risk factor for developing cancer. Age is a well-known risk factor as cancer incidence increases with age. Race can also influence cancer risk due to genetic and environmental factors. Lifestyle choices such as smoking, diet, and physical activity can significantly impact the likelihood of developing cancer. In contrast, ordinal petition in the family does not have a direct association with cancer risk.

Correct Answer: C

Rationale: The correct answer is C because the patient expressing fear of going home and being alone indicates apprehension about discharge. This is supported by stable vital signs and nearly healed incision, suggesting physical recovery. Choice A is incorrect as fear of being alone does not necessarily mean the patient can perform dressing changes independently. Choice B is incorrect as resuming medications is not related to the patient's fear of being alone. Choice D is incorrect as there is no evidence to suggest the surgery was unsuccessful based on the information provided.

Correct Answer: B

Rationale: The correct answer is B: 17 drops per minute. To calculate the correct drip rate, you need to use the formula: (Volume to be infused in mL / Time in minutes) x Drop factor. In this case, if the volume to be infused is 100 mL and the time is 60 minutes with a drop factor of 20, the calculation would be: (100 / 60) x 20 = 33.33 drops per minute. Since we cannot deliver fractional drops, the closest whole number is 17 drops per minute. This ensures the correct delivery rate for the medication. Choice A (6 drops per minute) is incorrect as it would be too slow and may not deliver the medication effectively. Choice C (50 drops per minute) and Choice D (100 drops per minute) are incorrect as they would both deliver the medication too quickly, potentially causing harm to the patient. The correct answer, 17 drops per minute, ensures a safe and accurate delivery rate

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen therapy. This is the priority intervention because a high temperature and diaphoresis indicate potential respiratory distress. Oxygen therapy can help improve oxygenation and support respiratory function. Providing frequent linen changes (B) is important for hygiene but not the priority. Fluid intake (C) is essential but not as urgent as addressing respiratory distress. Maintaining complete bed rest (D) may be necessary but addressing oxygenation takes precedence in this case.
