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 does the mnemonic PERLA stand for in the assessment of the eyes?

A. Pupils equally reactive to light and accommodation
B. Patient eyes are equally recessed and responsive to light and acuity
C. Patient eyes are equally responsive to light and acuity
D. Pupils equally reactive to light and acuity

Correct answer: A

Rationale: The correct answer is A: 'Pupils equally reactive to light and accommodation.' PERLA is a mnemonic used in eye assessments to check for Pupils being equally reactive to Light and Accommodation. Choice B is incorrect as it includes irrelevant information about the eyes being recessed. Choice C is incorrect as it is missing the mention of pupils and accommodation. Choice D is incorrect as it misses the mention of accommodation.

3. Round off these numbers to the nearest tenth:

A. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
B. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
C. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
D. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7

Correct answer: B

Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.

4. Jansen is receiving metformin (Glucophage). What will be the best plan of the nurse with regard to patient education with this drug? Select one that does not apply.

A. It stimulates the pancreas to produce more insulin.
B. It must be taken after meals.
C. It decreases sugar production in the liver.
D. It inhibits absorption of carbohydrates.

Correct answer: A

Rationale: The correct choice that does not apply is A. Metformin does not stimulate the pancreas to produce more insulin; instead, it works by decreasing sugar production in the liver, inhibiting carbohydrate absorption, and reducing insulin resistance. It is recommended to take metformin with meals to reduce gastrointestinal side effects. Option B is incorrect as metformin is usually taken with meals. Option D is also incorrect as metformin does not inhibit the absorption of carbohydrates.

5. A nurse is caring for a client who requests information about the prevalence of Tay-Sachs disease. Which of the following resources should the nurse use to obtain this information?

A. The client's health care provider
B. A collaborative, user-edited website
C. The facility's case manager
D. An evidence-based nursing journal

Correct answer: D

Rationale: An evidence-based nursing journal is the correct choice for the nurse to obtain information about the prevalence of Tay-Sachs disease. These journals contain peer-reviewed research and studies conducted by experts in the field, providing accurate and reliable information. Choice A, the client's health care provider, may have general information but may not provide detailed prevalence data. Choice B, a collaborative, user-edited website, is not a reliable source as the information may be inaccurate or outdated. Choice C, the facility's case manager, is unlikely to have specific prevalence data on Tay-Sachs disease.
