Nursing Elites

1. At 20 weeks gestation, a client is scheduled for an ultrasound. In preparing the client for the procedure, the nurse should explain that the primary reason for conducting this diagnostic study is to obtain which information?

• A. Sex and size of the fetus.
• B. Chromosomal abnormalities.
• C. Fetal growth and gestational age.
• D. Lecithin-sphingomyelin ratio.

Correct answer: C

Rationale: The primary reason for an ultrasound at 20 weeks gestation is to assess fetal growth, gestational age, and anatomical development. This evaluation helps ensure the fetus is developing appropriately and can detect any potential issues that may require intervention. Choices A, B, and D are incorrect because at 20 weeks, the primary focus of the ultrasound is not to determine the sex of the fetus, detect chromosomal abnormalities, or assess the lecithin-sphingomyelin ratio. While these factors may be evaluated in pregnancy, they are not the primary reasons for an ultrasound at 20 weeks gestation.

2. After a client delivered vaginally 2 days ago, what information should you share with her if she wants to resume using her diaphragm for birth control?

• A. The diaphragm is the most effective form of contraception.
• B. The diaphragm must be refitted after childbirth.
• C. Vaseline lubricant should be used when inserting the diaphragm.
• D. The diaphragm should be inserted 2 to 4 hours before intercourse.

Correct answer: B

Rationale: After childbirth, the diaphragm must be refitted to ensure a proper fit and effectiveness. Changes in the body post-delivery can affect the fit of the diaphragm, making it necessary to get refitted. Choice A is incorrect because while the diaphragm can be effective, it is not the most effective form of contraception. Choice C is incorrect because oil-based lubricants like Vaseline can damage latex diaphragms. Choice D is incorrect because the diaphragm should be inserted no more than 2 hours before intercourse, not 2 to 4 hours.

3. A 6-week-old infant diagnosed with pyloric stenosis has recently developed projectile vomiting. Which assessment finding indicates to the nurse that the infant is becoming dehydrated?

• A. Weak cry without tears.
• B. Bulging fontanel.
• C. Visible peristaltic wave.
• D. Palpable mass in the right upper quadrant.

Correct answer: A

Rationale: In infants, a weak cry without tears is a classic sign of dehydration. Tears are produced by the lacrimal glands, and reduced tear production is a result of dehydration. This assessment finding should alert the nurse to the infant's dehydration status, requiring prompt intervention to prevent further complications.

4. When can a woman who thinks she may be pregnant use a home pregnancy test to diagnose pregnancy?

• A. A home pregnancy test can be used right after your first missed period.
• B. These tests are most accurate after you have missed your second period.
• C. Home pregnancy tests often give false positives and should not be trusted.
• D. The test can provide accurate information when used right after ovulation.

Correct answer: A

Rationale: The correct answer is A. Home pregnancy tests detect hCG, a hormone produced during pregnancy, and are most accurate after the first missed period when hCG levels are higher. Testing too early may result in a false negative. Waiting until after the first missed period increases the reliability of the test results. Choice B is incorrect as waiting until after the second missed period is unnecessary and may delay seeking appropriate healthcare. Choice C is incorrect as home pregnancy tests are generally reliable when used correctly. Choice D is incorrect because ovulation occurs before the period, and testing immediately after ovulation may not provide accurate results.

5. After two miscarriages, a client is instructed to increase her daily intake of foods that include folic acid. The client does not like green leafy vegetables and states she is allergic to soy. Which food should the nurse suggest that the client eat to obtain folic acid?

• A. Strawberries.
• B. Yogurt.
• C. Collard greens.
• D. Whole milk.

Correct answer: C

Rationale: Collard greens are a good source of folic acid, which is important for preventing neural tube defects, especially in clients with a history of miscarriages. Since the client does not like green leafy vegetables, collard greens could be suggested as an alternative source of folic acid. Yogurt and whole milk do not contain significant amounts of folic acid, and while strawberries are a healthy choice, they are not a high source of folic acid compared to collard greens.
