HESI Maternity 55 Questions Quizlet
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 nurse reviews laboratory results for a client with glomerulonephritis. The client’s glomerular filtration rate (GFR) is 40 mL/min as measured by a 24-hour creatinine clearance. How should the nurse interpret this finding? (Select all that apply.)
- A. Excessive GFR
- B. Reduced GFR
- C. Fluid retention and risks for hypertension
- D. Pulmonary edema
Correct answer: B
Rationale: A GFR of 40 mL/min indicates a reduced glomerular filtration rate. In a healthy adult, the normal GFR ranges between 100 and 120 mL/min. A GFR of 40 mL/min signifies a significant reduction, leading to fluid retention and risks for hypertension and pulmonary edema due to excess vascular fluid. Choices A, C, and D are incorrect. Choice A is incorrect as a GFR of 40 mL/min is not excessive but rather reduced. Choices C and D do not directly address the interpretation of GFR but instead describe potential consequences of a reduced GFR.
3. What action should the nurse take if an infant, who was born yesterday weighing 7.5 lbs (3,402 grams), weighs 7 lbs (3,175 grams) today?
- A. Inform and assure the mother that this is normal weight loss.
- B. Encourage the mother to increase the frequency of breastfeeding.
- C. After verifying the accuracy of weight, notify the healthcare provider.
- D. Monitor the stool and urine output of the neonate for the last 24 hours.
Correct answer: A
Rationale: The correct action for the nurse to take in this situation is to inform and assure the mother that this weight loss is normal. Newborns can lose up to 10% of their birth weight in the first few days after birth, which is attributed to fluid loss and adjustment to life outside the womb. This weight loss is typically regained within the first two weeks of life. It is crucial for the nurse to educate and provide reassurance to the mother about this common occurrence in newborns.
4. A client's subjective data includes dysuria, urgency, and urinary frequency. What action should the nurse implement next?
- A. Collect a clean-catch specimen
- B. Administer prescribed antibiotics
- C. Perform a bladder scan
- D. Increase the client's fluid intake
Correct answer: A
Rationale: The correct action for the nurse to implement next is to collect a clean-catch specimen. This is essential to diagnose the cause of the client's symptoms accurately before initiating any treatment. Administering antibiotics (Choice B) without confirming the diagnosis through a specimen collection can be inappropriate and potentially harmful. Performing a bladder scan (Choice C) may not provide the necessary information to identify the specific cause of the symptoms. Increasing the client's fluid intake (Choice D) is a general recommendation and may not address the underlying issue causing the symptoms.
5. In the hierarchical organizational system, which of these is the most restrictive category?
- A. Genus
- B. Class
- C. Kingdom
- D. Species
Correct answer: D
Rationale: In the biological classification hierarchy, species is the most specific level, defining individual organisms that can interbreed. While genus, class, and kingdom are also categories in the hierarchy, they are broader and encompass a wider range of organisms compared to species. Genus groups together similar species, class groups similar orders, and kingdom is the broadest category grouping together similar phyla.
