A nurse is assisting with the care of a client who has severe preeclampsia and is receiving magnesium sulfate IV at 2 g/hr. Which of the following findings indicates that it is safe for the nurse to continue the infusion?

A. Respiratory rate of 16/min.

 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.

B. Heart rate of 60/min.

 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.

C. Urine output of 50 mL in 4 hr.

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.  

D. Diminished deep-tendon reflexes.

 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.

Full 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.

QUESTION

A nurse is assisting with the care of a client who is in labor and has the urge to push. Which of the following instructions should the nurse give the client?

A. "Take a deep, cleansing breath before and after each contraction.".

Cleansing breaths at the start and end of a contraction help to clear the lungs and focus the client. This technique ensures maximum oxygen delivery to the placenta and the fetus, preventing maternal hyperventilation and promoting relaxation between efforts.

B. "Hold your breath and push while I count to ten.".

Instructing the client to hold their breath and push while counting to ten is not recommended. This Valsalva maneuver can cause a sudden increase in intra-abdominal pressure, which may reduce blood flow to the heart and brain and may be harmful to both the client and the baby. It's crucial to promote safe pushing techniques during labor.

C. "You should push continuously throughout the entire contraction.".

The instruction to push continuously throughout the entire contraction is also not ideal. Pushing continuously can lead to exhaustion and decrease the effectiveness of each push. It's essential to guide the client on when and how to push effectively to prevent unnecessary fatigue.

D. "I will let you know when you should push according to your contractions.".

While the nurse monitors the monitor, the mother should be encouraged to listen to her body's natural urges. Relying solely on the nurse's direction can undermine the client's autonomy and may not align with the physiological peak of the urge.

Full Explanation

Choice A rationale: 

The nurse should not advise the client to take deep, cleansing breaths before and after each contraction because it can interfere with the natural urge to push and may not be effective in helping with the labor process. When a client feels the urge to push, it is essential to work with their body's natural instincts. 

Choice B rationale: 

Instructing the client to hold their breath and push while counting to ten is not recommended. This Valsalva manoeuvre can cause a sudden increase in intra-abdominal pressure, which may reduce blood flow to the heart and brain and may be harmful to both the client and the baby. It's crucial to promote safe pushing techniques during labor. 

Choice C rationale: 

The instruction to push continuously throughout the entire contraction is also not ideal. Pushing continuously can lead to exhaustion and decrease the effectiveness of each push. It's essential to guide the client on when and how to push effectively to prevent unnecessary fatigue.

Choice D rationale: 

The correct instruction is to let the client know when to push according to their contractions. The urge to push is a natural reflex that signifies the baby's descent into the birth canal. The nurse should encourage the client to listen to their body and push when they feel the urge during the contractions. This approach optimizes the client's efforts and conserves their energy for delivery.

QUESTION

A nurse is caring for a client who is pregnant and reports constipation. Which of the following recommendations should the nurse make?

A. Increased cellulose and fluid in the diet.

The nurse should recommend the client to increase cellulose and fluid in the diet. Cellulose is a type of fiber found in fruits, vegetables, and whole grains. Increasing fiber intake can help alleviate constipation by adding bulk to the stool and promoting regular bowel movements. Additionally, the recommendation to increase fluid intake complements the effect of fiber, as it softens the stool, making it easier to pass through the intestines. This combination of increased cellulose and fluid intake is a safe and natural way to address constipation during pregnancy without the need for medication or invasive interventions.

B. Regular use of glycerine suppositories.

Regular use of glycerine suppositories is not the best recommendation for pregnant clients experiencing constipation. Suppositories are inserted into the rectum to stimulate bowel movements and should only be used sparingly when other methods have failed. Pregnant individuals may have increased sensitivity, and it's essential to avoid unnecessary procedures or potential discomfort.

C. Regular use of a laxative.

Regular use of a laxative is also not the most suitable recommendation for a pregnant client with constipation. While laxatives can provide relief, they may lead to dependency and might have adverse effects on the developing fetus. It is best to explore safer and more natural methods before resorting to laxative use during pregnancy.

D. Maintenance of good posture.

Maintenance of good posture is essential during pregnancy for various rationales, but it is not a specific solution for constipation. While maintaining good posture can help alleviate back pain and other discomforts, it does not directly address the issue of constipation.
