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. A 38-week primigravida who works at a desk job and sits at a computer for 8 hours each day tells the nurse that her feet have begun to swell. Which instruction would be most effective in preventing pooling of blood in the lower extremities?

• A. Wear support stockings.
• B. Reduce salt in her diet.
• C. Move about every hour.
• D. Avoid constrictive clothing.

Correct answer: C

Rationale: During pregnancy, especially in the third trimester, it is common for women to experience swelling due to decreased circulation. Encouraging the patient to move about every hour helps prevent blood pooling in the lower extremities by promoting circulation. This simple activity can help alleviate swelling and discomfort associated with prolonged sitting.

3. A client whose labor is being augmented with an oxytocin (Pitocin) infusion requests an epidural for pain control. Findings of the last vaginal exam, performed 1 hour ago, were 3 cm cervical dilation, 60% effacement, and a -2 station. What action should the nurse implement first?

• A. Decrease the oxytocin infusion rate
• B. Determine current cervical dilation
• C. Request placement of the epidural
• D. Give a bolus of intravenous fluids

Correct answer: D

Rationale: In a client receiving an oxytocin infusion who requests an epidural, it is crucial to give a bolus of intravenous fluids first. This action helps prevent hypotension, a common side effect of epidural anesthesia, before the placement of the epidural. Maintaining adequate hydration is essential to support maternal blood pressure stability during the procedure.

4. An infant delivered vaginally by an HIV-positive mother is admitted to the newborn nursery. What intervention should the healthcare provider perform first?

• A. Bathe the infant with an antimicrobial soap.
• B. Measure the head and chest circumference.
• C. Obtain the infant's footprints.
• D. Administer vitamin K (AquaMEPHYTON).

Correct answer: A

Rationale: The initial intervention should be to bathe the infant with an antimicrobial soap to reduce the risk of HIV transmission from maternal fluids. This immediate action helps minimize potential exposure to the virus and promotes infection control practices in the care of infants born to HIV-positive mothers. Choice B, measuring head and chest circumference, is important for assessing growth and development but not the priority in this scenario. Choice C, obtaining footprints, is a routine procedure but not a priority over infection control measures. Choice D, administering vitamin K, is important for clotting factors but does not address the immediate risk of HIV transmission.

5. 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.
