A nurse is assisting with the care of a client who is in labour. Which of the following findings should the nurse report to the provider?
Fetal heart rate 100/min for a 10-min period.
Contraction resting period 35 seconds.
Contraction lasting 85 seconds.
Four contractions in a 10-min period.
The Correct Answer is C
Choice A rationale:
A fetal heart rate of 100/min for a 10-minute period is considered within the normal range. The normal fetal heart rate can range from 110 to 160 beats per minute, and a rate of 100 is not concerning.
Choice B rationale:
The resting period of a contraction refers to the time between contractions when the uterus is relaxed. A resting period of 35 seconds is also considered normal. In labor, the resting period between contractions allows the placenta to receive oxygen and nutrients, and 35 seconds is a rationaleable duration.
Choice C rationale:
A contraction lasting 85 seconds is abnormal and should be reported to the provider. Normally, contractions last around 60-90 seconds, but an 85-second contraction may indicate uterine hyperactivity or other issues that could potentially affect the well-being of both the mother and the baby.
Choice D rationale:
Having four contractions in a 10-minute period is considered normal during labor. In fact, an average pattern includes 3-5 contractions within a 10-minute window, so this finding is not a cause for concern.

Correct Answer is C
Explanation
Choice A rationale :
Scrambled eggs. Taking ferrous sulfate with scrambled eggs is not the optimal choice because eggs contain phytates, which can bind to iron and reduce its absorption. Therefore, it may hinder the effectiveness of the iron supplement, and the client may not receive the full benefit of the medication.
Choice B rationale
A high-fibre meal. While fiber is generally beneficial for digestion and overall health, it is not the best choice to take with ferrous sulfate. Fiber can also interfere with iron absorption in the same way as phytates, potentially reducing the medication's effectiveness.
Choice C rationale
Orange juice. The nurse should instruct the client to take the ferrous sulfate with orange juice. Orange juice is an excellent choice because it is rich in vitamin C. Vitamin C enhances the absorption of non-heme iron (the type of iron found in plant-based sources like ferrous sulfate). By taking the medication with orange juice, the client can maximize the absorption of iron and improve the treatment of iron-deficiency anaemia.
Choice D rationale
Milk. Consuming ferrous sulfate with milk is not advisable. Calcium, present in milk, can inhibit the absorption of iron. Therefore, taking the medication with milk might reduce the efficacy of the iron supplement and not provide the desired therapeutic effect.
Correct Answer is A
Explanation
The correct answer is choice A: Respiratory rate of 16/min.
Choice A rationale:
A respiratory rate of 16/min is within the normal range for adults, which is typically between 12 to 20 breaths per minute. In the context of severe preeclampsia, maintaining a normal respiratory rate is crucial when administering magnesium sulfate IV, as one of the signs of magnesium toxicity is respiratory depression. Therefore, a respiratory rate of 16/min indicates that the client is not experiencing respiratory depression and it is safe to continue the magnesium sulfate infusion.
Choice B rationale:
A heart rate of 60/min is at the lower end of the normal range, which is 60 to 100 beats per minute for adults. However, bradycardia or a low heart rate can be a sign of magnesium sulfate toxicity, especially if accompanied by other symptoms such as hypotension or altered mental status. Without additional context, a heart rate of 60/min alone does not necessarily indicate it is unsafe to continue the infusion, but it would require further assessment.
Choice C rationale:
A urine output of 50 mL in 4 hours is significantly below the expected minimum of 30 mL/hour for adults. Adequate urine output is an important indicator of kidney function and is essential for the excretion of magnesium. In the case of magnesium sulfate infusion for severe preeclampsia, a low urine output could indicate renal insufficiency and an increased risk of magnesium toxicity. Therefore, a urine output of 50 mL in 4 hours is a contraindication for continuing the infusion without further evaluation.
Choice D rationale:
Diminished deep-tendon reflexes can be a sign of magnesium toxicity. Deep-tendon reflexes are assessed to monitor for signs of magnesium overdose during infusion, as magnesium acts as a central nervous system depressant at high levels. If deep-tendon reflexes are diminished, it may suggest that the serum magnesium levels are too high, and the infusion should be paused or discontinued to prevent further toxicity.
In summary, the only finding that clearly indicates it is safe to continue the magnesium sulfate infusion is a normal respiratory rate, as provided in choice A. The other options either require further assessment or are indicators of potential magnesium toxicity.
