Correct Answer: A

Rationale: The correct answer is A because clients taking warfarin should have their INR (International Normalized Ratio) checked regularly to monitor the medication's effectiveness and adjust the dose if needed. This monitoring helps to ensure the medication is working correctly and the client is within the therapeutic range. Choice B is incorrect because clients on warfarin should not avoid leafy green vegetables but should maintain a consistent intake. Leafy green vegetables contain vitamin K, which can affect warfarin, so it's important to maintain a consistent intake to keep INR stable. Choice C is incorrect as clients should not stop taking warfarin abruptly without consulting their healthcare provider as it can lead to serious health risks like blood clots. Choice D is incorrect because while taking warfarin, it is important to avoid unnecessary aspirin use due to an increased risk of bleeding. However, this statement does not indicate an understanding of the teaching about the need for regular INR monitoring.

Correct Answer: D

Rationale: The correct action the nurse should take when preparing to administer an IV medication to a client with a latex allergy is to administer the medication through a latex-free IV port. This measure helps prevent allergic reactions in clients with a known latex allergy. Placing the client in a supine position (Choice A) is not directly related to preventing a latex allergy reaction. Using non-latex gloves (Choice B) is important for protecting the nurse or caregiver from latex exposure but does not prevent the client's allergic reaction. While using latex-free syringes (Choice C) is a good practice, ensuring the IV port is latex-free is more crucial in preventing an allergic response in the client.

Correct Answer: D

Rationale: The correct answer is D, dark-colored urine. Dark-colored urine can indicate various issues such as dehydration, liver problems, or blood in the urine, which could be concerning and require further evaluation by the provider. Choices A, B, and C are not necessarily findings that would need immediate reporting to the provider. A urine output of 50 mL in 2 hours might be low but could be influenced by various factors and might not always require immediate action. The presence of an indwelling urinary catheter is a known history and not a new finding. Frequent urination at night could be a symptom related to various conditions but may not be an urgent concern unless accompanied by other significant symptoms.

Correct Answer: B

Rationale: The correct answer is to rotate injection sites within the same region to prevent tissue damage. By rotating sites, the client can prevent lipodystrophy, which is a condition characterized by the loss or change in body fat at the site of repeated injections. This practice also helps to ensure proper insulin absorption. Storing unopened vials of insulin in the refrigerator (Choice A) is correct, not in the freezer, as freezing can damage the insulin. Administering insulin at a 90-degree angle (Choice C) is more appropriate for subcutaneous injections, while a 45-degree angle is used for intramuscular injections. Massaging the injection site after administering insulin (Choice D) is not recommended as it can affect insulin absorption rates.

Correct Answer: D

Rationale: The correct answer is D because avoiding public announcements about the baby's birth is crucial to reduce the risk of newborn abduction. Public announcements can attract unwanted attention and potentially jeopardize the safety of the newborn. Choices A, B, and C are incorrect. Choice A is incorrect because the baby's identification band should be kept on at all times for security purposes. Choice B is incorrect because leaving the baby unattended in the room can pose risks. Choice C is incorrect because identification bands are usually applied immediately after birth, not after the first bath.
