Nursing Elites

1. Which nutrient is most closely associated with the prevention of neural tube defects in a developing fetus for a woman planning to become pregnant?

• A. Calcium
• B. Folate
• C. Vitamin A
• D. Choline

Correct answer: B

Rationale: The correct answer is folate. Folate, also known as Vitamin B9, is vital for the prevention of neural tube defects in the developing fetus. It is primarily responsible for the creation and repair of DNA, which is essential during rapid growth stages such as pregnancy. While nutrients like calcium, vitamin A, and choline are important for pregnancy, they are not as directly linked to preventing neural tube defects as folate. Calcium is crucial for the baby's bone and teeth development. Vitamin A is essential for vision, immune function, and cellular growth. Choline supports brain development and neural functioning. However, none of these nutrients have the same direct impact on preventing neural tube defects as folate.

2. All of the following are contraindications when giving Immunization except:

• A. BCG Vaccine can be given to a child with AIDS
• B. BCG Vaccine can be given to a child with Hepatitis B
• C. DPT can be given to a child that had convulsion 3 days after being given the first DPT dose
• D. DPT can be given to a child with active convulsion or other neurological disease

Correct answer: B

Rationale: The correct answer is B. BCG vaccine can be given to a child with Hepatitis B, as there is no contraindication for this. Choice A, C, and D all present contraindications for administering immunizations. Choice A is incorrect because giving BCG vaccines to a child with AIDS is a contraindication. Choice C is incorrect as convulsions after the first DPT dose indicate a contraindication to subsequent doses. Choice D is incorrect because active convulsions or other neurological diseases are contraindications to receiving the DPT vaccine.

3. Why is a pulse oximeter attached to Mr. Dizon's finger?

• A. To determine if the patient's hemoglobin level is low and if he requires a blood transfusion
• B. To check the level of the patient's tissue perfusion
• C. To measure the effectiveness of the patient's anti-hypertensive medications
• D. To detect oxygen saturation of arterial blood before symptoms of hypoxemia develop

Correct answer: D

Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.

4. When doing an initial assessment, the best way for you to identify the client’s priority problem is to:

• A. Interview the client for chief complaints and other symptoms
• B. Talk to the relatives to gather data about history of illness
• C. Do auscultation to check for chest congestion
• D. Do a physical examination while asking the client relevant questions

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. The nurse notes that the fall might also cause a possible head injury. The patient will be observed for signs of increased intracranial pressure which include:

• A. Narrowing of the pulse pressure
• B. Vomiting
• C. Periorbital edema
• D. A positive Kernig's sign

Correct answer: C

Rationale: Periorbital edema is a sign of increased intracranial pressure. It is caused by fluid accumulation around the eyes due to compromised drainage. Narrowing of the pulse pressure is more indicative of shock than increased intracranial pressure. While vomiting can be a sign of increased intracranial pressure, it is not as specific as periorbital edema. A positive Kernig's sign is associated with meningitis, not increased intracranial pressure.
