Nursing Elites

1. A client who is at 24 weeks of gestation is receiving teaching about expected changes during pregnancy. Which of the following information should the nurse include?

• A. Your stomach will empty rapidly
• B. You should expect your uterus to double in size
• C. You should anticipate nasal stuffiness
• D. Your nipples will become lighter in color

Correct answer: C

Rationale: Nasal stuffiness is a common symptom during pregnancy due to increased blood flow and hormonal changes. This symptom is caused by the increased blood volume and hormonal changes that lead to swelling of the nasal passages. Choices A, B, and D are incorrect. Stomach emptying rate does not significantly change during pregnancy; the uterus does not double in size at 24 weeks but rather grows steadily, and nipples typically darken in color due to increased pigmentation.

2. Which field of biology studies heredity?

• A. Etiology.
• B. Ecology.
• C. Genetics.
• D. Eugenics.

Correct answer: C

Rationale: Genetics is the branch of biology that focuses on the study of heredity and variation in organisms. Etiology (choice A) deals with the causes of diseases, not heredity. Ecology (choice B) is concerned with the relationships between organisms and their environment, not specifically heredity. Eugenics (choice D) is a controversial field that involves improving the genetic quality of the human population through selective breeding, which is different from the study of heredity itself.

3. Which of the following statements about Rh incompatibility is true?

• A. Rh incompatibility occurs most commonly during a woman’s first pregnancy.
• B. Rh incompatibility is an untreatable condition that leaves a woman infertile for the rest of her life.
• C. Rh incompatibility is an abnormality that is transmitted from generation to generation and carried by a sex chromosome.
• D. Rh incompatibility occurs due to antibodies transmitted to a fetus during subsequent deliveries causing brain damage or death.

Correct answer: D

Rationale: Rh incompatibility occurs when the mother's antibodies attack the fetus's red blood cells, leading to serious complications, usually in subsequent pregnancies. Choice A is incorrect because Rh incompatibility often occurs in subsequent pregnancies, not necessarily the first one. Choice B is incorrect as Rh incompatibility does not render a woman infertile but can lead to complications during pregnancies. Choice C is incorrect as Rh incompatibility is not carried by a sex chromosome but involves the Rh factor on red blood cells.

4. On the first postpartum day, the nurse examines the breasts of a new mother. Which condition is the nurse most likely to find?

• A. Firm, larger, and very tender to the touch
• B. Slightly firm with an immediate let-down response
• C. Soft with no change from before delivery
• D. Filling and secreting colostrum

Correct answer: D

Rationale: On the first postpartum day, the nurse is most likely to find the breasts filling and secreting colostrum. Colostrum secretion is common as the body prepares for breastfeeding in the initial days after delivery. Choice A is incorrect as breasts are not typically very tender immediately postpartum. Choice B is incorrect as an immediate let-down response is more related to lactation rather than the first postpartum day. Choice C is incorrect as the breasts typically undergo changes, such as filling with colostrum, after delivery.

5. 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.
