Nursing Elites

1. A client is experiencing sore nipples from breastfeeding. Which of the following actions should the nurse take?

• A. Place a snug dressing on the client’s nipple when not breastfeeding
• B. Ensure the newborn’s mouth is wide open before latching to the breast
• C. Encourage the client to limit the newborn’s feeding to 10 minutes on each breast
• D. Instruct the client to begin the feeding with the nipple that is most tender

Correct answer: B

Rationale: Ensuring the newborn's mouth is wide open before latching is crucial for achieving a proper latch, which can help reduce nipple soreness. Placing a snug dressing on the nipple when not breastfeeding (choice A) can lead to further irritation and hinder healing. Encouraging the client to limit the newborn’s feeding to 10 minutes on each breast (choice C) may not be adequate for effective feeding as infants should feed until they are satisfied. Instructing the client to begin feeding with the most tender nipple (choice D) can worsen the soreness as it may not allow the baby to feed effectively.

2. Females with Turner syndrome:

• A. possess more thymine than cytosine.
• B. are taller than average.
• C. produce little estrogen.
• D. are more likely to give birth to twins.

Correct answer: C

Rationale: Turner syndrome is a chromosomal disorder in females characterized by short stature and underdeveloped ovaries, resulting in low estrogen production. This leads to symptoms such as delayed puberty and infertility. Choice A is incorrect because the chromosomal abnormality in Turner syndrome does not affect the thymine-cytosine ratio. Choice B is incorrect as females with Turner syndrome are typically shorter than average. Choice D is incorrect as Turner syndrome does not increase the likelihood of giving birth to twins.

3. In the structure of deoxyribonucleic acid (DNA), which of the following bases combines with thymine?

• A. Cytosine
• B. Adenine
• C. Rhodamine
• D. Serine

Correct answer: B

Rationale: The correct answer is B: Adenine. In the structure of DNA, adenine pairs with thymine through hydrogen bonding, forming one of the complementary base pairs that make up the double helix structure of DNA. Cytosine pairs with guanine, not thymine. Rhodamine and serine are not DNA bases and do not participate in DNA base pairing. Therefore, choices A, C, and D are incorrect.

4. A client with hyperemesis gravidarum is being cared for by a nurse. Which of the following laboratory tests should the nurse anticipate?

• A. Urine Ketones
• B. Rapid plasma reagin
• C. Prothrombin time
• D. Urine culture

Correct answer: A

Rationale: Urine ketones should be anticipated as a laboratory test for a client with hyperemesis gravidarum because it helps assess the severity of dehydration and malnutrition, which are common complications of this condition. Choice B, rapid plasma reagin, is a test for syphilis and is not relevant to hyperemesis gravidarum. Choice C, prothrombin time, is a measure of blood clotting function and is not typically indicated for hyperemesis gravidarum. Choice D, urine culture, is used to identify bacteria in the urine and is not directly related to assessing dehydration and malnutrition in clients with hyperemesis gravidarum.

5. Monozygotic (MZ) twins share _________ percent of their genes.

• A. 100
• B. 75
• C. 50
• D. 25

Correct answer: A

Rationale: Monozygotic (MZ) twins share 100% of their genes because they originate from the same fertilized egg that splits into two, resulting in identical genetic material for both twins. Choice B (75%) is incorrect as it implies a partial genetic similarity, which is not the case for MZ twins. Choice C (50%) is incorrect as it suggests half of the genes are shared, which is applicable to dizygotic (DZ) twins, not MZ. Choice D (25%) is incorrect as it indicates minimal genetic sharing, which is not true for MZ twins.
