How soon should delivery occur with a Category III FHR tracing?

Correct Answer: A

Rationale: Category III FHR tracings indicate abnormal fetal heart rate patterns that require immediate evaluation and intervention. In this case, delivery should occur within 15 minutes to prevent potential adverse outcomes for the fetus. Choice B (30 minutes) is incorrect because waiting an additional 15 minutes could lead to further deterioration of the fetal condition, increasing the risk of hypoxic injury or even fetal demise. Choice C (45 minutes) is also incorrect as it exceeds the recommended timeframe for delivery with a Category III FHR tracing. Waiting this long could result in significant harm to the fetus due to inadequate oxygenation. Choice D (60 minutes) is the furthest from the correct answer and poses the highest risk to the fetus. Delaying delivery for an hour with a Category III FHR tracing could have catastrophic consequences, including irreversible brain damage or stillbirth. In summary, the correct answer is A (15 minutes) because prompt delivery is crucial in cases of Category III FHR tracings to optimize fetal outcomes and minimize the risk of complications.

Correct Answer: C

Rationale: Placenta accreta is a serious pregnancy complication where the placenta attaches too deeply into the uterine wall. The most common cause of placenta accreta is a previous cesarean birth (Choice C). This is because during a cesarean section, the placenta can grow into the scar tissue from the previous surgery, making it difficult to detach during delivery. This increases the risk of placenta accreta in subsequent pregnancies. Choice A, malnutrition, is not a common cause of placenta accreta. While a poor diet can impact pregnancy outcomes, it is not directly linked to the development of placenta accreta. Choice B, smoking, is also not a common cause of placenta accreta. Smoking during pregnancy can lead to a variety of complications, but it is not a known risk factor for placenta accreta specifically. Choice D, obesity, is not the most common cause of placenta accreta, although it can be a risk factor. Obesity can lead to various pregnancy complications, but it is not as directly linked to placenta accreta as a previous cesarean birth. In conclusion, the most common cause of placenta accreta is a previous cesarean birth. It is important for healthcare providers to be aware of this risk factor in order to properly monitor and manage pregnancies at risk for placenta accreta.

Correct Answer: A

Rationale: Decreased capillary refill and diminished peripheral pulses are indicative of altered perfusion. Perfusion refers to the circulation of blood through tissues, providing them with oxygen and nutrients while removing waste products. When capillary refill is decreased, it means that blood is not flowing properly to the tissues, resulting in a delay in the return of color to the skin after pressure is applied. Diminished peripheral pulses also suggest inadequate blood flow to the extremities, which can lead to tissue damage and impaired function. Choice B, alteration in liver function, is incorrect because liver function does not directly affect capillary refill or peripheral pulses. Liver function is primarily related to metabolism, detoxification, and bile production. Choice C, alteration in kidney function, is also incorrect as kidney function is primarily related to filtration of blood and regulation of electrolytes and fluid balance. While kidney dysfunction can lead to fluid retention and altered blood volume, it does not directly affect capillary refill or peripheral pulses. Choice D, alteration in uterine function, is unrelated to the signs of decreased capillary refill and diminished peripheral pulses. Uterine function is primarily related to menstruation, pregnancy, and labor, and does not have a direct impact on blood flow to the extremities.

Correct Answer: A

Rationale: Complications from cocaine and methamphetamine use can be severe and potentially life-threatening. A common complication of using these drugs is seizures. Stimulant drugs like cocaine and methamphetamine can disrupt the normal electrical activity in the brain, leading to seizures. Seizures can range from mild to severe and can have serious consequences if not treated promptly. Hypotonic contractions (choice B) are not typically associated with cocaine and methamphetamine use. These drugs are more likely to cause hypertonic contractions, which can lead to complications during labor and delivery. Prolonged second stage labor (choice C) is not a common complication of cocaine and methamphetamine use. However, stimulant drugs can increase the risk of preterm labor and delivery, as well as other complications during pregnancy. Prolonged first stage labor (choice D) is also not a typical complication of cocaine and methamphetamine use. These drugs can cause vasoconstriction, which may affect the progression of labor, but it is not typically associated with prolonging the first stage of labor. In conclusion, seizures are a common and serious complication of cocaine and methamphetamine use due to their effects on brain function. Choices B, C, and D are incorrect because they do not accurately reflect the potential complications associated with these drugs.

Correct Answer: C

Rationale: The correct answer is C: Contraction stress test. When assessing a client's status during labor, it is essential for the nurse to perform a contraction stress test. This test involves monitoring the client's contractions to assess their frequency, duration, and strength. By analyzing the contraction pattern, the nurse can determine the progress of labor and the well-being of the fetus. This information is crucial in identifying any potential complications that may arise during labor and delivery. Option A, Fetal heart rate, is also an important assessment to perform during labor. Monitoring the fetal heart rate provides valuable information about the baby's well-being and can help identify signs of distress. However, this assessment alone may not provide a comprehensive picture of the client's status, which is why option C is the better choice. Option B, Contraction pattern, is closely related to the correct answer. While monitoring the contraction pattern is important, it is not enough on its own to fully assess the client's status. The contraction stress test provides a more detailed assessment of the contractions and their impact on the fetus. Option D, Vital signs, is also an essential assessment to perform during labor. Monitoring the client's vital signs, such as blood pressure and temperature, can help identify any signs of infection or other complications. However, vital signs alone may not provide enough information to accurately assess the client's status during labor, making option C the most appropriate choice for this question.
