Nokea
A preterm neonate develops physiologic jaundice and phototherapy is ordered. The nurse understands that this therapy:
- A. Activates the liver to dispose the bilirubin
- B. Breaks down the unconjugated bilirubin in the skin to conjugated form permitting excretion
- C. Activates Vit. K to facilitate excretion of the bilirubin
- D. Dissolves the bilirubin and allows it to be excreted from the skin
Correct Answer: B
Rationale: The correct answer is B because phototherapy works by breaking down unconjugated bilirubin in the skin to a water-soluble form, allowing it to be excreted from the body. This process does not activate the liver (choice A), nor does it activate Vitamin K (choice C) or dissolve the bilirubin for excretion from the skin (choice D). Phototherapy specifically targets the unconjugated bilirubin in the skin, converting it to a form that can be eliminated through the urine and stool.

A client at 37 weeks' gestation reports swollen feet and hands. What assessment finding requires immediate intervention?
- A. Blood pressure of 150/95 mmHg.
- B. Weight gain of 1 pound in a week.
- C. Mild nausea after eating.
- D. Fetal movements are regular.
Correct Answer: A
Rationale: The correct answer is A: Blood pressure of 150/95 mmHg. This finding indicates gestational hypertension, which can progress to preeclampsia, a serious condition that requires immediate intervention to prevent complications for both the mother and baby. High blood pressure can lead to organ damage and placental insufficiency.
B: Weight gain of 1 pound in a week is within the normal range for late pregnancy and may not require immediate intervention.
C: Mild nausea after eating is a common pregnancy symptom and does not indicate an urgent issue.
D: Regular fetal movements are a positive sign of fetal well-being and do not require immediate intervention.
The nurse is educating a client about folic acid during pregnancy. What food should the nurse recommend?
- A. Citrus fruits.
- B. Leafy green vegetables.
- C. Dairy products.
- D. Lean meats.
Correct Answer: B
Rationale: The correct answer is B: Leafy green vegetables. Folic acid is essential during pregnancy for proper fetal development. Leafy green vegetables like spinach, kale, and broccoli are rich sources of folic acid. Citrus fruits (Choice A) contain vitamin C but not as much folic acid as leafy greens. Dairy products (Choice C) provide calcium but are not significant sources of folic acid. Lean meats (Choice D) are good sources of protein but do not contain as much folic acid as leafy green vegetables. Therefore, recommending leafy green vegetables ensures the client gets an adequate intake of folic acid during pregnancy.
What is an advantage of the internal condom?
- A. It can be used by those who have a latex allergy.
- B. It can be used for repeated acts of intercourse.
- C. It has a lower failure rate than external condoms.
- D. It can be used for pleasure purposes.
Correct Answer: A
Rationale: The correct answer is A because the internal condom is made of nitrile, which is a non-latex material. This makes it suitable for individuals with latex allergies. Choice B is incorrect because both internal and external condoms can be used for repeated acts of intercourse. Choice C is incorrect because internal condoms do not necessarily have a lower failure rate than external condoms. Choice D is incorrect because while condoms can enhance pleasure during intercourse, the primary purpose of the internal condom is for protection rather than pleasure.
The nurse is assessing a client with suspected placenta previa. Which finding supports this diagnosis?
- A. Painful, bright red bleeding.
- B. Painless, bright red bleeding.
- C. Hard, rigid abdomen.
- D. Decreased fetal movements.
Correct Answer: B
Rationale: The correct answer is B: Painless, bright red bleeding. Placenta previa is characterized by painless vaginal bleeding due to the placenta covering the cervical os. Bright red blood indicates fresh bleeding from the lower uterus. This finding supports the diagnosis as it aligns with the classic presentation of placenta previa.
A: Painful, bright red bleeding is not characteristic of placenta previa, as the bleeding is usually painless.
C: A hard, rigid abdomen is more indicative of a uterine rupture or abruption, not placenta previa.
D: Decreased fetal movements are not directly associated with placenta previa; this finding may suggest fetal distress but is not specific to this condition.
The nurse is preparing a client for a biophysical profile (BPP). What does this test evaluate?
- A. Maternal blood flow to the placenta.
- B. Fetal genetic abnormalities.
- C. Fetal well-being, including movements and amniotic fluid.
- D. Cervical dilation and effacement.
Correct Answer: C
Rationale: The correct answer is C: Fetal well-being, including movements and amniotic fluid. A Biophysical Profile evaluates the fetus' health by assessing factors like fetal movements, muscle tone, breathing movements, amniotic fluid volume, and fetal heart rate patterns. This test provides valuable information about the fetus' well-being and helps in determining the need for interventions or further monitoring.
Explanation of why the other choices are incorrect:
A: Maternal blood flow to the placenta is not evaluated by a Biophysical Profile.
B: Fetal genetic abnormalities are not assessed through a BPP; it focuses on the fetus' current well-being.
D: Cervical dilation and effacement are related to labor progress and not part of a BPP, which focuses on fetal well-being.
