Correct Answer: B

Rationale: The correct answer is B because prolonged use of corticosteroids is a known risk factor for infections. Choice A is incorrect because frequent hand washing actually helps prevent infections. Choice C is incorrect as patient interaction is essential in healthcare but should be done following proper infection control measures. Choice D is also incorrect as restricting client movement is not a standard practice to prevent contamination.

Correct Answer: D

Rationale: When a patient is receiving IV potassium, it is crucial to monitor various parameters to ensure patient safety. Monitoring the ECG helps in identifying any potential dysrhythmias that may occur due to potassium imbalances. Monitoring urine output is important as potassium levels can affect renal function. Monitoring serum potassium levels is essential to assess the effectiveness of the IV potassium therapy. Therefore, all the options - monitoring ECG for dysrhythmias, urine output, and serum potassium levels - are necessary when administering IV potassium, making 'All of the above' the correct answer. Choices A, B, and C are not individually sufficient as they each address different aspects of patient monitoring when receiving IV potassium.

Correct Answer: C

Rationale: The correct answer is C: 'Take up to three tablets during a single angina episode.' Nitroglycerin can be taken up to three times during an episode to relieve angina. Choice A is incorrect because the client should place the tablet under the tongue and wait for it to dissolve, not wait for 10 minutes. Choice B is incorrect because taking up to five tablets during an angina episode is excessive and not recommended. Choice D is incorrect because nitroglycerin tablets are meant to be taken sublingually, not swallowed.

Correct Answer: A

Rationale: The correct answer is A: Pain Management. After abdominal surgery, one of the primary goals of post-operative care is to manage the patient's pain effectively to ensure their comfort and promote recovery. While wound care, prevention of complications, and ensuring digestive function are also important aspects of post-operative care, pain management takes precedence as it directly impacts the patient's well-being and recovery process.

Correct Answer: A

Rationale: The correct answer is A. Private room placement is crucial when caring for a patient with hepatitis A to prevent the transmission of the disease to others. Placing the child in a private room helps contain the infection and protect other patients and staff. Choices B, C, and D are incorrect because removing a toy from the child's bed, offering specific snacks, or using standard precautions, while important in general care, are not specific measures required to prevent the spread of hepatitis A.
