Nursing Elites

1. A healthcare provider is assessing a newborn who has a coarctation of the aorta. Which of the following should the provider recognize as a clinical manifestation of coarctation of the aorta?

• A. Increased blood pressure in the arms with decreased blood pressure in the legs
• B. Decreased blood pressure in the arms with increased blood pressure in the legs
• C. Increased blood pressure in both the arms and the legs
• D. Decreased blood pressure in both the arms and the legs

Correct answer: A

Rationale: The correct answer is increased blood pressure in the arms with decreased blood pressure in the legs. Coarctation of the aorta is a congenital heart defect characterized by a narrowing of the aorta, leading to increased blood pressure in the upper extremities and decreased blood pressure in the lower extremities due to decreased blood flow beyond the narrowing. Choice B is incorrect because coarctation of the aorta does not lead to increased blood pressure in the legs. Choice C is incorrect because increased blood pressure in both the arms and legs is not a typical manifestation of coarctation of the aorta. Choice D is incorrect because decreased blood pressure in both the arms and legs is not characteristic of coarctation of the aorta.

2. When advising a woman considering pregnancy on nutritional needs to reduce the risk of giving birth to a newborn with a neural tube defect, what information should the nurse include?

• A. Limit alcohol consumption.
• B. Increase intake of iron-rich foods.
• C. Consume foods fortified with folic acid.
• D. Avoid foods containing aspartame.

Correct answer: C

Rationale: The correct answer is C: Consume foods fortified with folic acid. Folic acid plays a crucial role in preventing neural tube defects. It is advised to consume foods fortified with folic acid or take a supplement containing at least 400 micrograms of folic acid daily. This nutrient is essential for the developing fetus and can significantly reduce the risk of neural tube defects when taken before and during early pregnancy. Choices A, B, and D are incorrect. While limiting alcohol consumption is important during pregnancy, it is not directly related to reducing the risk of neural tube defects. Increasing intake of iron-rich foods is essential for preventing anemia but is not specifically linked to neural tube defects. Avoiding foods containing aspartame is generally recommended, but it is not directly related to reducing the risk of neural tube defects.

3. A client in a prenatal clinic is pregnant and experiencing episodes of maternal hypotension. The client asks the nurse what causes these episodes. Which of the following responses should the nurse make?

• A. This is due to an increase in blood volume.
• B. This is due to pressure from the uterus on the diaphragm.
• C. This is due to the weight of the uterus on the vena cava.
• D. This is due to increased cardiac output.

Correct answer: C

Rationale: Maternal hypotension during pregnancy is often caused by the weight of the uterus pressing on the vena cava when the client is lying on her back, which reduces blood flow to the heart. This compression can lead to a decrease in blood pressure and subsequent symptoms of hypotension. Choice A is incorrect because an increase in blood volume typically leads to increased blood pressure rather than hypotension. Choice B is incorrect as pressure from the uterus on the diaphragm is not a common cause of maternal hypotension. Choice D is incorrect because increased cardiac output would not directly cause maternal hypotension.

4. A client who is at 36 weeks of gestation and has a prescription for a nonstress test is being taught by a nurse. Which of the following statements should the nurse include in the teaching?

• A. You will receive IV fluid before this test.
• B. The procedure will take approximately 10 to 15 minutes.
• C. You will be offered orange juice to drink during the test.
• D. You will need to sign an informed consent form before each test.

Correct answer: C

Rationale: The correct statement the nurse should include in the teaching is that the client will be offered orange juice to drink during the nonstress test. This is because offering the client orange juice, or another beverage high in glucose, will help stimulate the fetus during the procedure, aiding in obtaining accurate results. Choice A is incorrect because IV fluid is not typically administered before a nonstress test. Choice B is incorrect as the procedure usually takes around 20 to 40 minutes. Choice D is incorrect as informed consent is typically obtained once for the procedure, not before each individual test.

5. A nurse is caring for a preterm newborn who is in an incubator to maintain a neutral thermal environment. The father of the newborn asks the nurse why this is necessary. Which of the following responses should the nurse make?

• A. Preterm newborns have a smaller body surface area than normal newborns.
• B. The added brown fat layer in a preterm newborn reduces his ability to generate heat.
• C. Preterm newborns lack adequate temperature control mechanisms.
• D. The heat in the incubator rapidly dries the sweat of preterm newborns.

Correct answer: C

Rationale: The correct answer is C because preterm newborns have immature temperature regulation mechanisms, making it difficult for them to maintain their body temperature. An incubator helps maintain a stable thermal environment. Choice A is incorrect as the body surface area is not the primary reason for needing an incubator. Choice B is incorrect because brown fat in preterm newborns actually helps generate heat. Choice D is incorrect as the purpose of the incubator is not to dry sweat but to regulate the newborn's temperature.
