LPN Fundamentals Practice Questions

Correct Answer: A

Rationale: When assisting a client with bilateral casts on her hands with feeding, the nurse should sit at the bedside. This action is crucial to provide the client with the nurse's full attention during the feeding process. Sitting at the bedside helps avoid appearing rushed and ensures a safe and comfortable environment for the client. Choices B, C, and D are incorrect because while they may be relevant in other situations, the priority when assisting a client with bilateral casts on her hands is to ensure proper attention and a comfortable setting during feeding.

Correct Answer: B

Rationale: When administering a subcutaneous injection, inserting the needle at a 90-degree angle is appropriate. This angle helps ensure proper delivery of the medication into the subcutaneous tissue. Using a 1-inch needle is common for subcutaneous injections to reach the subcutaneous fat layer adequately. Tuberculin syringes are typically used for intradermal injections, not subcutaneous injections. Aspirating before injecting is not necessary for subcutaneous injections as it is primarily used for intramuscular injections to ensure the needle is not in a blood vessel.

Correct Answer: B

Rationale: The correct answer is B: 'I should consume foods low in sodium.' This statement indicates an understanding of managing hypertension. Excessive sodium intake can lead to increased blood pressure, so reducing sodium consumption is crucial in hypertension management to prevent complications. Choices A, C, and D are incorrect. Consuming foods low in potassium is not typically recommended for hypertension management as potassium-rich foods like fruits and vegetables can be beneficial. Consuming foods high in saturated fats and cholesterol can be detrimental to cardiovascular health and should be limited in individuals with hypertension.

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: C

Rationale: The correct instruction for the nurse to include during postoperative teaching following a hip arthroplasty is to 'Place a pillow between your legs when turning.' Placing a pillow between the legs when turning is crucial as it helps prevent dislocation of the hip prosthesis. This position aids in maintaining proper alignment and stability, thereby reducing the risk of complications after hip arthroplasty surgery. Choices A, B, and D are incorrect because they do not directly address the specific action needed to protect the hip prosthesis and prevent complications.
