Correct Answer: D

Rationale: The correct answer is D: "I will listen for background noises." Listening for background noises can provide useful information about the bomb's location, helping security to assess the situation more effectively. Choice A is incorrect because disconnecting the call abruptly may prevent gathering important details. Choice B is incorrect as using elevators during a bomb threat can be dangerous; it is safer to use stairs for evacuation. Choice C is incorrect because actively engaging with the caller to gather information is crucial in bomb threat situations.

Correct Answer: B

Rationale: The most important action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. This action helps prevent obstruction, ensures proper drainage, and reduces the risk of infection. Changing the catheter every 72 hours is not necessary unless clinically indicated and may introduce unnecessary risk. Cleaning the perineal area with antiseptic solution daily is important for general hygiene but not the most critical action for catheter-related infection prevention. Irrigating the catheter with normal saline every shift is not a routine nursing intervention for catheter care and may increase the risk of introducing pathogens.

Correct Answer: D

Rationale: Gingival hyperplasia is a significant side effect associated with phenytoin therapy. It is characterized by an overgrowth of gum tissue, which can lead to issues such as difficulty in speaking, eating, and maintaining proper oral hygiene. This condition can progress rapidly and may require immediate intervention by the healthcare provider to prevent further complications. Increased appetite, dry mouth, and nausea/vomiting are common side effects of various medications, but they are not as urgent or serious as gingival hyperplasia in a client taking phenytoin.

Correct Answer: B

Rationale: The correct answer is B: 'Blood transfusions are forbidden.' Jehovah's Witnesses typically refuse blood transfusions due to their religious beliefs. This is crucial for the LPN to consider when planning the client's care to ensure that alternative treatments are explored. Choices A, C, and D are incorrect as they do not align with the specific beliefs and practices of Jehovah's Witnesses. Autopsy prohibition, alcohol use restrictions, and dietary preferences are not primary concerns related to the religious beliefs of Jehovah's Witnesses.

Correct Answer: C

Rationale: To calculate the drops per minute for the IV infusion, first determine the total drops to be infused over 8 hours. 1,000 ml to be infused over 8 hours means 125 ml per hour (1000 ml / 8 hours = 125 ml/hr). Since the infusion set delivers 10 drops per ml, 125 ml/hr x 10 drops/ml = 1250 drops/hr. To find drops per minute, divide the drops per hour by 60 (minutes in an hour): 1250 drops/hr / 60 minutes = 20.83 drops/minute, which rounds up to 21 drops per minute (Option C). This rate ensures the correct infusion rate over 8 hours. Choices A, B, and D are incorrect calculations and do not provide the appropriate infusion rate needed to administer the IV over the specified time period.
