1. Multifetal pregnancies with triplets occur at a rate of 1 in 8,100 births, but twins occur much more frequently with a rate of:

• A. 1 in 85 births.
• B. 1 in 5400 births.
• C. 1 in 2700 births.
• D. 1 in 540 births

Correct answer: A

Rationale: The correct answer is A: 1 in 85 births. The rate of twin pregnancies is approximately 1 in 85 births. This means that twins are more common compared to triplets, which occur at a rate of 1 in 8,100 births. Choices B, C, and D are incorrect because they do not reflect the correct frequency of twin pregnancies as stated in the question.

2. What is a major concern about the health-care system in the United States?

• A. Emphasis on disease prevention
• B. Quality of care
• C. Collaborative care
• D. Reduction in hospital-acquired drug-resistant infections

Correct answer: B

Rationale: The major concern about the health-care system in the United States is the quality of care provided. While disease prevention and collaborative care are important aspects, the primary focus of concern is ensuring that the care delivered meets high standards in terms of effectiveness, safety, and patient outcomes. Reduction in hospital-acquired drug-resistant infections, although relevant, is not the primary concern when evaluating the overall quality of healthcare services.

3. Which atrioventricular heart block is also referred to as Mobitz II?

• A. Third-degree atrioventricular heart block
• B. Second-degree atrioventricular heart block
• C. First-degree atrioventricular heart block
• D. Complete heart block

Correct answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.

4. The doctor has ordered 20 cc per hour of normal saline intravenously for your pediatric patient. You will be using pediatric intravenous tubing that delivers 60 cc per drop. How many drops per minute will you administer using this pediatric intravenous set?

• A. 30 drops per minute
• B. 25 drops per minute
• C. 20 drops per minute
• D. 22 drops per minute

Correct answer: C

Rationale: To calculate the drops per minute, first convert the ordered amount to drops per minute. 20 cc per hour equals 20 drops per hour with 60 cc per drop tubing, which is equivalent to 20 drops per hour * 60 cc per drop = 1200 drops per hour. To find drops per minute, divide 1200 by 60 (minutes in an hour), which equals 20 drops per minute. Therefore, the correct answer is 20 drops per minute. Choices A, B, and D are incorrect as they do not reflect the correct calculation based on the provided information.

5. A nurse is reviewing laboratory results and notes that a client's serum sodium level is 150 mEq/L. The nurse reports the serum sodium level to the physician, and the physician prescribes dietary instructions based on the sodium level. Which food item should the nurse instruct the client to avoid?

• A. Peas
• B. Cauliflower
• C. Low-fat yogurt
• D. Processed oat cereals

Correct answer: D

Rationale: The correct answer is processed oat cereals. Processed oat cereals are often high in sodium content, which should be avoided in cases of hypernatremia. Peas, cauliflower, and low-fat yogurt are generally low in sodium and are not typically contraindicated in hypernatremia. Therefore, choices A, B, and C are incorrect.
