1. A client who is 24 weeks gestation arrives at the clinic reporting swollen hands. On examination, the nurse notes the client has had a rapid weight gain over six weeks. Which action should the nurse implement next?
- A. Review the client's previous blood pressures in the chart.
- B. Obtain the client's blood pressure.
- C. Observe and time the client's contractions.
- D. Examine the client for pedal edema.
Correct answer: B
Rationale: Swollen hands and rapid weight gain could be signs of preeclampsia, so the next step is to check the client's blood pressure. Elevated blood pressure is a key indicator in assessing for preeclampsia in pregnancy. Reviewing the client's previous blood pressures may provide additional context but obtaining the current blood pressure is crucial for immediate assessment. Observing and timing contractions are not relevant in this scenario as the client is not presenting with signs of active labor. Examining for pedal edema is important in assessing for fluid retention, but obtaining the blood pressure takes precedence in this case due to the potential seriousness of preeclampsia.
2. What causes cystic fibrosis?
- A. Sex-linked abnormality.
- B. Abnormality in the 21st pair of chromosomes.
- C. Recessive gene.
- D. Single segment found only on the Y chromosome.
Correct answer: C
Rationale: Cystic fibrosis is a genetic disorder caused by inheriting two copies of a recessive gene, one from each parent. This means that both parents must carry at least one copy of the faulty gene for a child to inherit the condition. Choice A is incorrect because cystic fibrosis is not linked to the sex chromosomes. Choice B is incorrect as cystic fibrosis is not caused by an abnormality in the 21st pair of chromosomes but by a specific gene mutation. Choice D is also incorrect as cystic fibrosis is not related to the Y chromosome, which is specific to males.
3. What maternal factor should the nurse identify as having the greatest impact on the development of spina bifida occulta in a newborn?
- A. Short interval between pregnancies
- B. Folic acid deficiency
- C. Preeclampsia
- D. Tobacco use
Correct answer: B
Rationale: Folic acid deficiency during pregnancy is a well-known risk factor for neural tube defects, including spina bifida occulta, making supplementation critical in prenatal care. Folic acid plays a crucial role in neural tube formation during early pregnancy. Short intervals between pregnancies do not directly impact the development of spina bifida occulta. Preeclampsia is a hypertensive disorder of pregnancy and is not directly linked to spina bifida occulta. While tobacco use during pregnancy has various adverse effects, it is not the primary factor influencing the development of spina bifida occulta in newborns.
4. 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.
5. Is a low sperm count or lack of sperm the most common infertility problem in men?
- A. TRUE
- B. FALSE
- C. Rarely
- D. Never
Correct answer: A
Rationale: A low sperm count or lack of sperm is indeed one of the most common causes of infertility in men. Factors such as hormonal imbalances, genetic issues, reproductive anatomy problems, and lifestyle factors can also contribute to male infertility. Choice B is incorrect because a low sperm count is a prevalent issue among men facing infertility, making it a common problem. Choices C and D are incorrect as they do not accurately reflect the prevalence of low sperm count as a cause of infertility in men.
