HESI Maternity 55 Questions
1. A client who is 5 days postpartum is being taught about signs of effective breastfeeding. Which information should the nurse include in the teaching?
- A. Feeling a tugging sensation when the baby is sucking
- B. Expecting the baby to have two to three wet diapers in a 24-hour period
- C. The baby’s urine should appear dark and concentrated
- D. The breast should stay firm after the baby breastfeeds
Correct answer: A
Rationale: Feeling a tugging sensation while the baby is sucking indicates an effective latch and milk transfer during breastfeeding. This sensation means that the baby is effectively drawing milk from the breast. Choice B is incorrect because infants should ideally have six to eight wet diapers in a 24-hour period to show adequate hydration. Choice C is incorrect as a dark and concentrated urine may indicate dehydration, which is not a sign of effective breastfeeding. Choice D is incorrect as the breast should soften after the baby breastfeeds, indicating that the baby has effectively emptied the breast of milk.
2. A client is in the second stage of labor. Which of the following manifestations should the nurse expect?
- A. The client expels the placenta
- B. The client experiences gradual dilation of the cervix
- C. The client begins having regular contractions
- D. The client delivers the newborn
Correct answer: D
Rationale: During the second stage of labor, the cervix is fully dilated, and the client delivers the newborn. The expulsion of the placenta occurs during the third stage of labor, not the second stage. Regular contractions typically begin in the first stage of labor, not the second. Gradual dilation of the cervix occurs during the first stage of labor, specifically during the active phase.
3. A client is experiencing preterm labor and has a prescription for 4 doses of dexamethasone 6 mg IM every 12 hours. The available concentration is dexamethasone 10 mg/mL. How many mL of dexamethasone should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use trailing zero.)
- A. 0.6 mL
- B. ---
- C. ---
- D. ---
Correct answer: A
Rationale: Calculation: (6 mg/dose) / (10 mg/mL) = 0.6 mL per dose. The correct answer is 0.6 mL. This calculation is obtained by dividing the dose needed (6 mg) by the concentration available (10 mg/mL). The resulting value is 0.6 mL per dose. Choices B, C, and D are not applicable as the correct answer has been calculated accurately.
4. Chromosomes contain thousands of segments called:
- A. nuclei.
- B. nodes.
- C. capillaries.
- D. genes.
Correct answer: D
Rationale: Chromosomes are structures composed of DNA and genes. Genes are the functional segments within chromosomes that encode specific traits and characteristics. The other choices ('nuclei,' 'nodes,' 'capillaries') do not accurately describe the segments found within chromosomes and are unrelated to their structure or function.
5. An individual’s phenotype reflects both genetic and environmental influences.
- A. phenotype
- B. chromosome
- C. allele
- D. genotype
Correct answer: A
Rationale: The correct answer is A: phenotype. A phenotype is the observable characteristics of an individual, which result from the interaction of their genotype with the environment. This interaction between genetics and the environment determines how genes are expressed and how traits are manifested in an individual. Choices B, C, and D are incorrect because chromosomes, alleles, and genotypes are components of an individual's genetic makeup, but they do not directly reflect the observable traits influenced by both genetics and the environment.
