Correct Answer: D

Rationale: Verifying the pH of the gastric aspirate is the correct action to take before administering an intermittent enteral feeding through an NG tube. This step ensures proper tube placement in the stomach, as the gastric aspirate should have an acidic pH (usually below 5). Heating the feeding solution, elevating the head of the bed, or flushing the tube with saline are not directly related to verifying tube placement and are not the immediate actions needed before administering the feeding.

Correct Answer: B

Rationale: The correct answer is B. An FHR baseline of 170/min is considered tachycardia, which is above the normal range during labor and requires immediate attention. High FHR can indicate fetal distress or maternal fever. Choice A, contractions lasting 80 seconds, are within normal range for active labor. Choice C, early decelerations in the FHR, are usually benign and do not typically require immediate intervention. Choice D, a temperature of 37.4°C (99.3°F), is within normal limits.

Correct Answer: B

Rationale: Using a 7th-grade reading level is the most effective technique when creating education material for clients because it ensures that the content is easily understood by a wide range of individuals. Option A, emphasizing important information with bold lettering, may help draw attention but doesn't guarantee comprehension. Option C, avoiding cartoons, is not necessarily a universal rule and can sometimes make material more engaging. Option D, using words with three or four syllables, can make the material more complex and harder to understand, defeating the purpose of effective communication in education material.

Correct Answer: B

Rationale: During an acute exacerbation of Crohn's disease, the nurse should maintain the client on a low-residue diet. This diet helps to minimize bowel irritation by reducing the volume and frequency of stools. Choices A, C, and D are incorrect. Encouraging the client to increase dietary fiber (Choice A) and eat a high-fiber diet (Choice D) can worsen symptoms and aggravate bowel inflammation in Crohn's disease. Providing the client with frequent high-calorie snacks (Choice C) may not be appropriate during an exacerbation since high-fat foods can be harder to digest and may exacerbate symptoms.

Correct Answer: A

Rationale: Substernal retractions indicate respiratory distress in a sickle-cell client, which can be a sign of acute chest syndrome. This condition is a serious complication of sickle-cell anemia characterized by chest pain, fever, cough, and shortness of breath. Reporting this symptom promptly is crucial for timely intervention. Choice B, hematuria, is not typically associated with acute chest syndrome but may indicate other issues such as a urinary tract infection. Choice C, a temperature of 37.9°C (100.2°F), is slightly elevated but not a specific indicator of acute chest syndrome. Choice D, sneezing, is not a typical symptom of acute chest syndrome and would not warrant immediate reporting to the provider in this context.
