A nurse is reinforcing teaching with a client who is at weeks of gestation and scheduled for a non-stress test (NST). Which of the following statements by the client indicates a need for further teaching?
I need to schedule the test when the baby is usually active
I have to lie on my back during the test
The baby’s heart rate will be monitored during the test
I will be able to go to the bathroom during the test if necessary
The Correct Answer is B
Rationale for Choice A:
It is accurate that scheduling the NST when the baby is usually active is beneficial. This is because fetal movement is expected to cause accelerations in the fetal heart rate, which is a positive sign of fetal well-being.
By scheduling the test during a time of typical fetal activity, the chances of obtaining a reactive NST (a normal result) are increased.
Therefore, this statement does not indicate a need for further teaching.
Rationale for Choice B:
Lying on the back during the NST is not recommended.
This position can cause the weight of the uterus to compress the major blood vessels (the inferior vena cava and aorta), potentially reducing blood flow to the placenta and fetus.
Reduced blood flow can, in turn, lead to a decrease in fetal heart rate and movement.
To avoid this, the recommended position for NST is a semi-Fowler's position, which involves being partially reclined with the head and upper body elevated.
This position helps to promote uterine perfusion and prevent supine hypotension.
Rationale for Choice C:
It is accurate that the baby's heart rate will be monitored during the NST.
This is the primary purpose of the test: to assess the fetal heart rate response to fetal movement. Therefore, this statement does not indicate a need for further teaching.
Rationale for Choice D:
It is accurate that the client will be able to go to the bathroom during the NST if necessary. The test is noninvasive and does not require strict immobility.
The client can move around and use the bathroom as needed, as long as the fetal heart rate monitor is not disconnected.
Therefore, this statement does not indicate a need for further teaching.

Correct Answer is E
Explanation
Choice A rationale:
Maternal battering, or physical abuse during pregnancy, is a risk factor for placental abruption. However, it is not the most common risk factor. Studies have shown that the incidence of placental abruption is about 2-4 times higher in women who have experienced physical abuse during pregnancy compared to those who have not. However, the overall prevalence of physical abuse during pregnancy is estimated to be around 4-8%, while the prevalence of maternal hypertension is much higher, affecting about 10-15% of pregnancies.
Choice B rationale:
Cigarette smoking is also a risk factor for placental abruption. The nicotine in cigarettes causes vasoconstriction, which can reduce blood flow to the placenta. This can lead to placental abruption, especially in women who smoke heavily. However, while smoking is a significant risk factor, it is still less common than maternal hypertension.
Choice C rationale:
Maternal age is associated with an increased risk of placental abruption. Women over the age of 35 are at a higher risk than younger women. This is likely due to changes in the blood vessels of the uterus that occur with age. However, age alone is not as strong a predictor as hypertension.
Choice D rationale:
Maternal cocaine use is a significant risk factor for placental abruption. Cocaine causes vasoconstriction and can also lead to high blood pressure. This combination of factors can significantly increase the risk of placental abruption. However, cocaine use is much less prevalent than hypertension in the general population.
Choice E rationale:
Maternal hypertension, or high blood pressure during pregnancy, is the most common risk factor for placental abruption. Hypertension can damage the blood vessels in the uterus, which can lead to placental abruption. Approximately 50% of placental abruptions are associated with hypertension.
Correct Answer is B
Explanation
Choice A rationale:
A blood pressure of 100/60 is within the normal range and does not pose a contraindication to oral contraceptives. While hypertension (high blood pressure) can be a contraindication, a blood pressure of 100/60 is not considered hypertensive.
However, it's essential to monitor blood pressure regularly in individuals using oral contraceptives, as some may experience a slight increase in blood pressure.
Choice B rationale:
Age is a significant factor when considering oral contraceptive use.
Adolescents under 16 years of age are generally not recommended to use oral contraceptives due to several concerns: Their reproductive systems are still developing, and hormonal contraceptives could potentially disrupt normal growth and development.
Younger adolescents may have more difficulty adhering to a strict daily medication regimen, which is crucial for the effectiveness of oral contraceptives.
They may be at a higher risk of certain side effects, such as irregular bleeding patterns and mood changes.
Acne treatment is often a primary reason for considering oral contraceptives in adolescents. However, alternative acne treatments that are more suitable for younger individuals are available.
Choice C rationale:
A hematocrit of 39 is within the normal range for females and does not contraindicate oral contraceptive use.
Hematocrit measures the proportion of red blood cells in the blood. Oral contraceptives can sometimes cause slight changes in hematocrit levels, but these changes are typically not clinically significant.
Choice D rationale:
A menstrual cycle of 14 days is considered a normal variation and does not pose a contraindication to oral contraceptives. Oral contraceptives can often regulate irregular menstrual cycles, so they may even be beneficial for individuals with shorter or longer cycles.
