Correct Answer: C

Rationale: The correct instruction the nurse should include is to rotate injection sites within the same body area. This practice helps prevent lipodystrophy, a condition characterized by the thickening or thinning of subcutaneous fat at the injection sites, which can affect insulin absorption. Choice A is incorrect because administering insulin in the same area each time can lead to lipodystrophy. Choice B is incorrect as insulin should be stored according to the manufacturer's instructions, which may include refrigeration. Choice D is incorrect because the angle of insulin injection (usually 90 degrees) is determined by the length of the needle and the amount of subcutaneous fat, not a fixed 45-degree angle.

Correct Answer: B

Rationale: During a Weber test, the nurse should place an activated tuning fork in the middle of the client's forehead. This test is used to assess for lateralization of sound in a client with possible hearing issues. Choice A is incorrect because the Weber test does not involve delivering high-pitched sounds at random intervals. Choice C is incorrect as it describes the Rinne test, not the Weber test. Choice D is incorrect as whispering words into one ear is not part of the Weber test procedure.

Correct Answer: A

Rationale: Choice A is correct because performing ankle and knee exercises every hour helps prevent contractures and other adverse effects of immobility. Contractures are a common complication of immobility, and range of motion (ROM) exercises can help maintain joint flexibility and prevent contractures. This statement indicates an understanding of the teaching provided by the healthcare provider. Choices B, C, and D are incorrect. Holding the breath when rising from a sitting position can increase the risk of orthostatic hypotension, not reduce adverse effects of immobility. Removing antiembolic stockings while in bed can compromise their effectiveness in preventing deep vein thrombosis (DVT), which is not a measure to reduce immobility-related complications. Having a partner help change positions every 4 hours may not be frequent enough to prevent immobility-related complications effectively; changing positions more frequently is usually recommended to prevent issues like pressure ulcers and muscle stiffness.

Correct Answer: A

Rationale: Pharyngeal diphtheria is primarily spread through droplet transmission, which occurs when an infected person coughs, sneezes, or talks, releasing respiratory droplets containing the bacteria. Therefore, the correct precaution for caring for a client with pharyngeal diphtheria is droplet precautions. Droplet precautions help prevent the transmission of respiratory pathogens over short distances via respiratory droplets. Contact precautions are used for diseases spread through direct or indirect contact with the patient or their environment. Airborne precautions are used for diseases that spread through small droplets suspended in the air. Standard precautions are basic infection prevention practices applying to all patient care.

Correct Answer: B

Rationale: The correct answer is B. Adding liquid medication to pudding can help with swallowing difficulties, demonstrating understanding of the instructions. Options A and C are incorrect as altering time-release capsules and enteric-coated pills is not recommended in medication administration. Option A is incorrect as time-release capsules should not be opened and sprinkled on food, affecting their efficacy. Option C is incorrect as crushing enteric-coated pills can affect their absorption. Option D is unrelated to medication administration and does not demonstrate understanding of the instructions.
