LPN Fundamentals Practice Questions

Correct Answer: B

Rationale: The priority finding is the clear fluid leaking from the nose, which could indicate a cerebrospinal fluid leak and potential brain injury. This requires immediate attention to assess for possible cerebrospinal fluid leak, which is a serious complication of head trauma and needs prompt intervention to prevent further complications. While a Glasgow Coma Scale score of 13 may indicate a mild alteration in consciousness, it is not as urgent as assessing for a cerebrospinal fluid leak. Nausea and vomiting are common symptoms after head injuries but do not take precedence over assessing for a potential cerebrospinal fluid leak. Anisocoria (unequal pupils) is also important to note but is not as urgent as identifying a possible cerebrospinal fluid leak in this scenario.

Correct Answer: B

Rationale: The correct answer is B. Decreasing the intake of purine-rich foods is essential in managing gout as purines break down into uric acid, contributing to gout symptoms. Increasing purine-rich foods would exacerbate the condition by increasing uric acid levels. Therefore, choice A is incorrect. Choices C and D are also incorrect as increasing sodium-rich foods (choice C) is not recommended for gout management, and decreasing potassium-rich foods (choice D) is unrelated to gout.

Correct Answer: B

Rationale: Measuring the tube from the client's nose to the earlobe to the xiphoid process ensures the tube is inserted to the correct depth. This measurement helps prevent complications such as tube misplacement or lung insertion. Positioning the client with the head of the bed elevated to 30� is important to facilitate easier insertion but is not the most crucial step. Lubricating the entire length of the tube with water-soluble lubricant is essential for smooth insertion but is not the most critical action. Instructing the client to cough during insertion is not necessary and may lead to unnecessary discomfort.

Correct Answer: A

Rationale: The correct statement to include in teaching a client with type 1 diabetes mellitus is that they can still eat sugar, but they must count it in their carbohydrate intake for the day. This is important because clients with type 1 diabetes need to manage their blood glucose levels by calculating their carbohydrate intake, including sugars. Choice B is incorrect because total avoidance of sugar is not necessary, but monitoring and including it in the carbohydrate count is essential. Choice C is incorrect as proteins and fats can also affect blood glucose levels and should be consumed in moderation. Choice D is incorrect since oral hypoglycemic agents are not used in type 1 diabetes mellitus, as insulin replacement therapy is the mainstay of treatment.

Correct Answer: A

Rationale: Elevating the head of the bed to 30� is the correct action to take when a client is receiving continuous enteral feedings through a nasogastric tube. This position helps prevent aspiration of the enteral feedings into the lungs, reducing the risk of aspiration pneumonia. Additionally, elevating the head of the bed promotes proper digestion and absorption of the feedings by utilizing gravity to facilitate movement into the stomach and through the gastrointestinal tract. Flushing the tube with water every 2 hours (Choice B) is not necessary for continuous feedings and may disrupt the feeding schedule. Replacing the feeding bag and tubing every 72 hours (Choice C) is not the standard recommendation unless there are specific concerns or complications. Checking the client's gastric residual every 8 hours (Choice D) is important but not the immediate action needed to prevent aspiration during enteral feedings.
