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: D

Rationale: The correct answer is D because contractions every 5 minutes that last 30 seconds indicate that the rate of infusion should be increased. This pattern suggests weak contractions or intervals that are too far apart, requiring an adjustment to improve labor progress. Option A is incorrect as a low urine output is not directly related to the need for an increase in the oxytocin infusion rate. Option B, Montevideo units consistently at 300 mm Hg, is incorrect because it is a measure of intrauterine pressure and does not determine the need for an increase in oxytocin infusion. Option C, FHR pattern with absent variability, is incorrect as it may indicate fetal distress but does not specifically relate to the need for adjusting the oxytocin infusion rate.

Correct Answer: B

Rationale: The correct answer is B. Wearing loose clothing around the ICD is essential to avoid putting pressure on the device, which can interfere with its function. Choices A, C, and D are incorrect. Soaking in a tub rather than showering is not relevant to ICD care. Stopping the use of a microwave oven is not necessary with an ICD. Holding a cellphone on the same side as the ICD is not recommended as it can potentially interfere with the device.

Correct Answer: D

Rationale: The correct answer is D, a heart rate of 160/min. A heart rate of 160/min in a newborn exceeds the normal range and could indicate potential issues that need further evaluation by the provider. Acrocyanosis (choice A) is a common finding in newborns and is not concerning. Vernix caseosa (choice B) is a white, cheesy substance found on newborn skin and is a normal finding. While a respiratory rate of 50/min (choice C) is slightly elevated, it is not as concerning as a high heart rate in a newborn.

Correct Answer: A

Rationale: The correct answer is A. A lack of tear production is a sign of severe dehydration in infants, indicating the need for IV therapy. Option B, bulging fontanels, is a sign of increased intracranial pressure, not dehydration. Option C, breathing slower than normal, and Option D, decreasing heart rate, are not specific signs of severe dehydration that would indicate the need for IV therapy in this case.
