Correct Answer: C

Rationale: To administer magnesium sulfate 2 g/hr IV, the healthcare professional should set the IV infusion pump to administer 50 mL/hr. The calculation is as follows: 20 g / 500 mL = 2 g / X mL, X = 50 mL/hr. Choice A (60 mL/hr) is incorrect as it does not match the calculated rate. Choice B (30 mL/hr) is incorrect as it is half of the calculated rate. Choice D (80 mL/hr) is incorrect as it is higher than the calculated rate.

Correct Answer: C

Rationale: A weight gain of 2.2 kg (4.8 lb) in a week is above the expected reference range for a client at 38 weeks of gestation and could indicate complications such as preeclampsia or gestational hypertension. Rapid weight gain at this stage requires immediate attention and should be reported to the provider for further evaluation and management. Choices A, B, and D are not the priority findings to report to the provider at this stage of gestation. Blood pressure of 136/88 mm Hg is within normal limits in pregnancy, insomnia is common in the third trimester, and Braxton-Hicks contractions are expected in the third trimester as the body prepares for labor.

Correct Answer: A

Rationale: It is crucial to cover the newborn's eyes with an opaque eye mask to prevent damage to the retinas and corneas from the phototherapy light. The eyes are particularly sensitive to the light used in phototherapy, and shielding them helps protect the newborn's delicate eyes from potential harm. Choice B is incorrect because the newborn should be undressed to maximize skin exposure to the phototherapy light. Choice C is incorrect because lotions or oils can interfere with the effectiveness of phototherapy. Choice D is incorrect because the newborn should be kept as still as possible to maximize exposure to the light.

Correct Answer: B

Rationale: A newborn's respiratory rate can vary between 20 to 100 breaths per minute during the initial phase after birth. A respiratory rate as low as 18 breaths per minute at this early stage requires immediate nursing intervention. This finding necessitates further assessment to ensure adequate oxygenation and respiratory function. The other options, heart rate of 168/min, tremors, and fine crackles, are within normal limits for a full-term newborn and do not require immediate intervention.

Correct Answer: B

Rationale: Early decelerations in the FHR are benign and are typically caused by fetal head compression during contractions. In this case, with the client at 39 weeks of gestation and on oxytocin, it is important for the nurse to continue monitoring the client. Early decelerations do not require intervention as they are a normal response to certain stimuli and do not indicate fetal distress. Discontinuing the oxytocin infusion (Choice A) is not necessary as early decelerations are not related to oxytocin administration. Requesting the provider to assess the client (Choice C) is not needed for early decelerations as they are a normal finding. Increasing the infusion rate of the maintenance IV fluid (Choice D) is not indicated and would not address the early decelerations. Therefore, the appropriate action is to continue monitoring the client and reassess as needed.
