Nursing Elites

1. 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.

2. What maternal behavior is typically observed when a new mother first receives her infant?

• A. She eagerly reaches for the infant, undresses the infant, and examines the infant completely.
• B. Her arms and hands receive the infant and she then traces the infant's profile with her fingertips.
• C. Her arms and hands receive the infant and she then cuddles the infant to her own body.
• D. She eagerly reaches for the infant and then holds the infant close to her own body.

Correct answer: B

Rationale: When a new mother first receives her infant, a typical maternal behavior is to use her arms and hands to receive the infant and then trace the infant's profile with her fingertips. This action is a gentle way of bonding with the newborn and aids in recognizing the infant's features. Choices A, C, and D are incorrect as they do not accurately describe the common behavior of tracing the infant's profile, which is a significant part of the initial interaction between a mother and her newborn.

3. A 6-year-old child is diagnosed with rheumatic fever and demonstrates associated chorea (sudden aimless movements of the arms and legs). Which information should the nurse provide to the parents?

• A. Muscle tension decreases with fine motor skill projects, so these activities should be encouraged.
• B. The chorea or movements are temporary and will eventually disappear.
• C. Permanent lifestyle changes are not needed to promote safety in the home.
• D. Consistent discipline is not directly related to controlling the movements.

Correct answer: B

Rationale: Chorea, or sudden aimless movements associated with rheumatic fever, is temporary in nature and will eventually disappear on its own. It is important for the nurse to reassure the parents that these movements are part of the condition and typically resolve over time without the need for permanent lifestyle changes or strict discipline. Providing accurate information and reassurance to the parents can help alleviate concerns and promote understanding of the condition's course. Choices A, C, and D are incorrect because muscle tension, permanent lifestyle changes, and consistent discipline are not directly related to the resolution of chorea in rheumatic fever.

4. 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.

5. In developing a teaching plan for expectant parents, the nurse plans to include information about when the parents can expect the infant's fontanels to close. The LPN/LVN bases the explanation on knowledge that for the normal newborn, the

• A. anterior fontanel closes at 2 to 4 months and the posterior by the end of the first week.
• B. anterior fontanel closes at 5 to 7 months and the posterior by the end of the second week.
• C. anterior fontanel closes at 8 to 11 months and the posterior by the end of the first month.
• D. anterior fontanel closes at 12 to 18 months and the posterior by the end of the second month.

Correct answer: D

Rationale: The anterior fontanel typically closes between 12 to 18 months, while the posterior fontanel usually closes by the end of the second month. It is important for parents to know these timeframes as it helps in monitoring the normal growth and development of their newborn. Delayed closure of fontanels may indicate potential health issues, and early closure may also warrant further evaluation by healthcare providers.
