1. What does a QRS Complex represent in an ECG reading?

• A. Atrial depolarization
• B. Ventricular repolarization
• C. Ventricular depolarization
• D. End of ventricular depolarization

Correct answer: C

Rationale: The QRS Complex in an ECG reading represents ventricular depolarization, which is the process of the heart's ventricles preparing to contract by changing the electrical charge in the cell, hence choice 'C' is the correct answer. Choice 'A' is incorrect because atrial depolarization is represented by the P wave in an ECG reading, not the QRS Complex. Choice 'B' is incorrect as ventricular repolarization is depicted by the T wave, not the QRS Complex. Finally, choice 'D' is also incorrect because the QRS Complex is not the end of ventricular depolarization, but the process itself.

2. 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.

3. A nurse is planning care for a client who reports increasing difficulty swallowing food. Which of the following interventions should the nurse plan to take?

• A. Turn on the client’s television during meals.
• B. Place the client into a semi-reclining position for meals.
• C. Encourage the client to rest prior to mealtimes.
• D. Encourage the client to use a straw when drinking liquids.

Correct answer: C

Rationale: The correct answer is to encourage the client to rest prior to mealtimes. This intervention can help reduce fatigue and improve the ability to swallow. Turning on the client’s television during meals (choice A) may distract the client but does not directly address the swallowing issue. Placing the client into a semi-reclining position for meals (choice B) can help with swallowing difficulties, but resting before meals is more beneficial. Encouraging the client to use a straw when drinking liquids (choice D) is not the priority intervention for swallowing difficulties in this scenario.

4. A client has acute dysphagia. Which of the following nursing interventions should be included in the plan of care?

• A. Providing a straw for consumption of liquids
• B. Encouraging larger bites
• C. Placing the client in semi-Fowler's position during meals
• D. Instructing the client to tilt head forward when swallowing

Correct answer: C

Rationale: Placing the client in semi-Fowler's position during meals is the correct intervention for a client with acute dysphagia. This position helps prevent aspiration by facilitating swallowing. Providing a straw for consumption of liquids (Choice A) can increase the risk of aspiration and is not recommended for clients with dysphagia. Encouraging larger bites (Choice B) can also increase the risk of choking and aspiration. Instructing the client to tilt the head forward when swallowing (Choice D) is not the recommended technique for managing dysphagia as it does not address the underlying issue effectively.

5. What is considered an acceptable LDL cholesterol level for children and adolescents?

• A. Less than 70 mg/dL
• B. Less than 110 mg/dL
• C. Less than 129 mg/dL
• D. Less than 170 mg/dL

Correct answer: B

Rationale: An LDL cholesterol level of less than 110 mg/dL is considered acceptable and healthy for children and adolescents. This level helps reduce the risk of cardiovascular diseases. Choices A, C, and D are incorrect because an LDL cholesterol level below 110 mg/dL is the recommended target for children and adolescents to maintain good heart health.
