LPN Fundamentals Practice Questions

Correct Answer: B

Rationale: Edema at the infusion site is an indication of infiltration, where fluid leaks into the surrounding tissues causing swelling. This can compromise the delivery of medication and fluids, potentially leading to complications. Redness, warmth, and oozing of blood are more suggestive of inflammation or infection rather than infiltration. Infiltration requires prompt recognition and intervention to prevent further issues with the IV therapy.

Correct Answer: B

Rationale: The correct answer is B. Administering an intramuscular injection at a 90� angle is essential for proper medication delivery into the muscle tissue. Injecting at a 45� angle is incorrect for intramuscular injections and is typically used for subcutaneous injections where the needle is inserted into the fatty tissue layer beneath the skin. Choice A is correct as selecting a 25-gauge needle is appropriate for an intramuscular injection. Choice C is also correct as the ventrogluteal site is a suitable site for intramuscular injections. Choice D is correct as aspirating for blood return is a necessary step to ensure the needle is not in a blood vessel before injecting the medication.

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 answer is A. Increasing intake of high-fiber foods is essential in managing diverticulitis as it helps prevent constipation and promotes bowel regularity, reducing the risk of complications and improving overall colon health. Choice B is incorrect because decreasing high-fiber foods can worsen diverticulitis symptoms. Choices C and D are also incorrect as increasing high-fat foods can exacerbate diverticulitis, while decreasing high-fat foods is generally recommended to manage the condition.

Correct Answer: A

Rationale: The correct answer is A: 'I should increase my intake of foods high in iron.' Iron-deficiency anemia is managed by increasing the consumption of iron-rich foods to improve iron levels in the body. Foods high in iron include red meat, poultry, fish, beans, lentils, and iron-fortified cereals. Choices B, C, and D are incorrect because decreasing intake of iron-rich foods or increasing intake of calcium-rich foods would not address the deficiency in iron levels that characterizes iron-deficiency anemia.
