HESI Maternity 55 Questions

Correct Answer: A

Rationale: The most appropriate nursing diagnosis for a woman experiencing severe preeclampsia is 'Risk for injury to mother and fetus, related to central nervous system (CNS) irritability.' Severe preeclampsia poses a significant risk of injury to both the mother and the fetus due to complications such as seizures, stroke, and placental abruption. 'Risk for altered gas exchange' is not the priority diagnosis as pulmonary edema is more common in severe preeclampsia. 'Risk for deficient fluid volume' is incorrect as sodium retention in severe preeclampsia often leads to fluid overload. 'Risk for increased cardiac output' is also incorrect as antihypertensive drugs are used to reduce cardiac output in this condition.

Correct Answer: B

Rationale: When a newborn is receiving phototherapy, it is important to avoid using lotions or ointments on their skin as these products can lead to skin irritation and burns under the phototherapy lights. Dressing the newborn in lightweight clothing helps ensure proper exposure to the phototherapy lights. Keeping the newborn supine during treatment helps maximize exposure to the light. However, the key consideration in this scenario is to prevent skin irritation and burns by avoiding lotions or ointments.

Correct Answer: A

Rationale: The correct answer is A: codominance. Codominance refers to a genetic scenario where both alleles in a gene pair are fully expressed, leading to a phenotype that displays traits from both alleles equally. This is distinct from incomplete dominance where the traits blend. Choices B, C, and D are incorrect. Preponderance does not specifically relate to the expression of alleles. Ascendance and concurrence do not describe the genetic concept of codominance where both alleles are fully expressed.

Correct Answer: A

Rationale: The correct answer is to increase the infusion rate every 30 to 60 minutes. This approach allows for the careful monitoring and adjustment of oxytocin administration during labor induction. Choice B is incorrect because maintaining the client in a supine position can decrease blood flow to the placenta and compromise fetal oxygenation. Choice C is incorrect as titrating the infusion rate by 4 milliunits/min is not a standard practice for oxytocin administration. Choice D is incorrect as limiting IV intake to 4 L per 24 hours is not specifically related to the administration of oxytocin for labor induction.

Correct Answer: D

Rationale: Diethylstilbestrol (DES) is a synthetic estrogen that was prescribed to pregnant women in the 1940s and 1950s to prevent miscarriages. However, it was later discovered that DES exposure in utero could lead to health issues in offspring, including an increased risk of testicular, vaginal, and cervical cancer. Choice A, Androsterone, is a steroid hormone produced in small amounts in humans and unlikely to be associated with the adverse effects described. Choice B, Adiponectin, is a protein hormone that plays a role in regulating glucose levels and fatty acid breakdown, not related to the adverse effects mentioned. Choice C, Progestin, is a synthetic form of progesterone used in birth control and hormone therapy, not linked to the specific health concerns associated with DES exposure.
