Correct Answer: B

Rationale: The correct answer is B. Insulin glargine has a 24-hour duration of action, making it suitable for once-daily dosing for long-term blood sugar control. Choice A is incorrect as insulin glargine is a long-acting insulin with no pronounced peak effect in its action profile. Choice C is incorrect as insulin glargine is usually given at the same time each day regardless of meals. Choice D is incorrect as there is no specific requirement to avoid eating before or after taking insulin glargine.

Correct Answer: D

Rationale: The correct instruction for cord care is to keep the cord stump dry until it falls off. This helps prevent infection and promotes healing. Choice A is incorrect because the timing of when the cord stump falls off can vary, usually between 1-3 weeks. Choice B is incorrect as a black cord stump can be a normal part of the healing process, so it is unnecessary to contact the provider for this reason. Choice C is incorrect because cleaning the cord with hydrogen peroxide daily is not recommended as it can delay healing and cause irritation.

Correct Answer: A

Rationale: The correct action the nurse should take is to administer the medication over 60 minutes. This is important because administering vancomycin over 60 minutes helps prevent red man syndrome, a reaction that can occur with rapid infusion. Monitoring the client's blood glucose level (Choice B) is unrelated to vancomycin administration. Infusing the medication rapidly (Choice C) is incorrect and can lead to adverse reactions. Administering the medication using a filter needle (Choice D) is unnecessary for vancomycin administration.

Correct Answer: B

Rationale: The correct action for the nurse to take is to check the placement of the nasogastric tube every 8 hours. This is crucial to ensure that the tube is correctly positioned in the stomach, reducing the risk of complications such as aspiration. Administering the feeding using a large-bore syringe (Choice A) is not recommended for enteral nutrition. Flushing the tube with water every 6 hours (Choice C) is not necessary for continuous enteral nutrition. Maintaining the client in an upright position (Choice D) is generally preferred to reduce the risk of aspiration, but it is not the most critical action compared to verifying tube placement.

Correct Answer: C

Rationale: Administering anticoagulants as prescribed is a crucial intervention for clients with pulmonary embolism to prevent further clot formation. Encouraging the client to ambulate frequently may dislodge the clot and lead to worsening symptoms. Placing the client in a prone position can compromise respiratory function. Initiating seizure precautions is not directly related to the management of pulmonary embolism.
