Correct Answer: B

Rationale: A contraction duration of 90 seconds can indicate uterine tachysystole, which may lead to fetal hypoxia. Uterine tachysystole is defined as more than five contractions in 10 minutes, averaged over a 30-minute window. Contractions every 2 minutes (Choice A) may occur in active labor but need to be assessed in conjunction with other factors. A fetal heart rate of 150/min (Choice C) is within the normal range. Urine output of 60 mL/hr (Choice D) is also within the expected range for a client in labor.

Correct Answer: B

Rationale: The correct instruction for a client in the first trimester of pregnancy experiencing nausea is to consume small, frequent meals. This helps alleviate nausea by preventing an empty stomach and maintaining stable blood sugar levels. Drinking water with meals can sometimes exacerbate nausea, especially in the case of morning sickness. Eating high-fat foods can be heavy on the stomach and worsen nausea. Lying down after eating can lead to reflux and is not recommended, especially for pregnant individuals experiencing nausea.

Correct Answer: B

Rationale: Applying counterpressure to the sacrum can help alleviate lower back pain during labor by reducing pressure on the nerves. Effleurage on the abdomen, back massage with lavender oil, and administering opioid analgesics are not specifically targeted at relieving lower back pain, making them less effective interventions in this scenario.

Correct Answer: D

Rationale: The nurse should report a urine output of 20 mL/hr. This finding can indicate decreased renal perfusion and possible development of preeclampsia, which is a severe complication of gestational hypertension. Inadequate urine output can suggest compromised kidney function and impaired maternal and fetal well-being. Options A, B, and C are within normal limits for a client with gestational hypertension and may not require immediate reporting to the provider.
