Which finding meets the criteria of a reassuring fetal heart rate (FHR) pattern?
Variability averages between 6 and 10 beats/min.
Mild late deceleration patterns occur with some contractions.
FHR does not change as a result of fetal activity.
Average baseline rate ranges between 100 and 140 beats/min.
The Correct Answer is A
Choice A reason: Variability refers to the fluctuations in the FHR that are irregular in amplitude and frequency. It reflects the balance between the sympathetic and parasympathetic nervous systems of the fetus. A normal variability is between 6 and 10 beats/min, which indicates a healthy and well-oxygenated fetus.
Choice B reason: Late decelerations are decreases in the FHR that begin after the peak of a contraction and return to the baseline after the contraction ends. They are caused by uteroplacental insufficiency, which means that the placenta is not delivering enough oxygen and nutrients to the fetus. Mild late decelerations are not reassuring and may indicate fetal hypoxia or acidosis².
Choice C reason: FHR should change as a result of fetal activity, such as movement, sleep, or stimulation. A change in the FHR indicates a responsive and well-oxygenated fetus. A lack of change in the FHR may indicate fetal distress or compromise.
Choice D reason: The average baseline rate is the mean FHR rounded to increments of 5 beats/min during a 10-minute window, excluding periods of marked variability, accelerations, or decelerations. A normal baseline rate is between 110 and 160 beats/min. A baseline rate between 100 and 140 beats/min is not necessarily abnormal, but it may indicate fetal bradycardia (slow heart rate) or tachycardia (fast heart rate), depending on the gestational age and other factors.

Correct Answer is C
Explanation
Choice A reason: A sleepy, sedated affect is not a concerning sign, as it is a common side effect of magnesium sulfate. Magnesium sulfate is a central nervous system depressant that can cause drowsiness, lethargy, and reduced alertness.
Choice B reason: Absent ankle clonus is not a concerning sign, as it indicates a normal neuromuscular response. Ankle clonus is a rhythmic jerking of the foot when the ankle is dorsiflexed. It is a sign of hyperreflexia, which can occur in severe preeclampsia due to increased blood pressure and cerebral edema.
Choice C reason: A respiratory rate of 10 breaths/min is a concerning sign, as it indicates respiratory depression. This is a serious complication of magnesium sulfate toxicity, which can lead to respiratory arrest and death. The nurse should monitor the woman's respiratory rate closely and report any signs of respiratory distress.
Choice D reason: Deep tendon reflexes of 2+ are not a concerning sign, as they indicate a normal neuromuscular response. Deep tendon reflexes are graded from 0 to 4, with 2 being the average. Magnesium sulfate can cause hyporeflexia or areflexia, which are signs of magnesium sulfate toxicity.
Correct Answer is ["A","B","E","F"]
Explanation
Choice A reason: Limiting time spent wearing a wet bathing suit is a good preventive measure, as it can reduce the moisture and warmth that can promote the growth of bacteria and fungi in the genital area. The nurse should advise the 15-year old to change into dry clothes as soon as possible after swimming or bathing.
Choice B reason: Not douching is a good preventive measure, as it can preserve the natural balance of the vaginal flora and pH. The nurse should explain to the 15-year old that douching can wash away the protective mucus and lactobacilli that prevent infections, and it can also introduce harmful substances or microorganisms into the vagina.
Choice C reason: Wearing nylon undergarments is not a good preventive measure, as it can trap heat and moisture in the genital area and create a favorable environment for infections. The nurse should recommend the 15-year old to wear cotton or breathable fabrics that can absorb sweat and allow air circulation.
Choice D reason: Using floral scented bath salts is not a good preventive measure, as it can irritate the genital mucosa and alter the vaginal pH. The nurse should caution the 15-year old to avoid using any products that contain perfumes, dyes, or chemicals in the genital area, as they can cause allergic reactions or infections.
Choice E reason: Decreasing sugar intake is a good preventive measure, as it can lower the risk of yeast infections. The nurse should educate the 15-year old that sugar can feed the growth of Candida albicans, which is a common cause of vaginal candidiasis. The nurse should also encourage the 15-year old to eat a balanced diet that includes probiotics, such as yogurt, to maintain a healthy vaginal flora.
Choice F reason: Avoiding tight-fitting jeans is a good preventive measure, as it can prevent friction and pressure on the genital area. The nurse should suggest the 15-year old to wear loose or comfortable clothing that can reduce the risk of skin irritation or injury, which can lead to infections.
