Which is fetal tachycardia likely caused by?

Correct Answer: B

Rationale: The correct answer is B: Maternal infection. Maternal infection can lead to fetal tachycardia due to the transfer of inflammatory mediators from the mother to the fetus, causing an increase in the fetal heart rate. This physiological response is a common indicator of fetal distress in utero. A: Compression of the umbilical cord can lead to fetal distress, but it typically manifests as bradycardia rather than tachycardia. C: Compression of the fetal head can cause fetal distress, but it is more likely to result in decelerations in heart rate rather than tachycardia. D: Maternal hypertension can lead to complications during pregnancy, but it is not typically associated with fetal tachycardia.

Correct Answer: B

Rationale: The correct answer is B: Hands and knees position. This position helps relieve pressure on the lower back by allowing the baby to shift away from the mother's spine, reducing back pain. It also promotes optimal fetal positioning for labor progress. A: Supine with knees bent may worsen back labor by putting pressure on the spine. C: Lying flat on the left side does not actively alleviate back pain or assist with fetal positioning. D: Sitting upright in a chair may not provide the same relief as the hands and knees position since it doesn't encourage the baby to shift position away from the back.

Correct Answer: A

Rationale: The correct answer is A: Preeclampsia. In this scenario, the sudden onset of severe headache and blurry vision in a pregnant woman in labor are indicative of preeclampsia, a serious pregnancy complication characterized by high blood pressure and signs of organ damage. The nurse should assess for other symptoms of preeclampsia such as hypertension, proteinuria, edema, and epigastric pain. Preeclampsia can lead to eclampsia, seizures, and life-threatening complications for both the mother and the baby if not promptly managed. Summary: B: Fetal distress - Not the priority assessment when the mother is experiencing symptoms indicative of a serious maternal condition like preeclampsia. C: Uterine rupture - Symptoms are not suggestive of uterine rupture, which typically presents with severe abdominal pain, vaginal bleeding, and signs of shock. D: Placenta previa - Symptoms are not consistent with placenta previa, which typically

Correct Answer: B

Rationale: The correct answer is B: Hands and knees position. This position helps relieve back pain during labor by promoting optimal fetal positioning, reducing pressure on the back, and allowing gravity to assist in the descent of the baby. It also opens up the pelvic outlet, making it easier for the baby to navigate through the birth canal. Incorrect choices: A: Supine position can worsen back pain as it puts pressure on the lower back and restricts blood flow to the uterus. C: Lithotomy position can exacerbate back pain as it involves lying on the back with legs in stirrups, which can increase pressure on the back. D: Squatting position may not be ideal for relieving back pain in this scenario as it can put additional strain on the back muscles and may not provide optimal support for the laboring individual.

Correct Answer: B

Rationale: The correct answer is B: "You can have the epidural now since you are in active labor." At 6cm dilation, the patient is typically considered to be in active labor, making it an appropriate time to offer an epidural for pain relief. Administering the epidural at this stage can help manage the pain effectively and provide relief during the remainder of labor. Other choices are incorrect because waiting until 8cm dilation (Choice A) may cause unnecessary suffering, administering after the second stage (Choice C) is too late for pain relief, and giving it during the latent phase (Choice D) is not ideal as the patient may not be in active labor yet.
