Maternity HESI Test Bank
1. What determines a child’s sex?
- A. Presence of teratogens at the time of conception.
- B. Sex chromosome received from the mother.
- C. Presence of teratogens at the time of ovulation.
- D. Sex chromosome received from the father.
Correct answer: D
Rationale: The correct answer is the sex chromosome received from the father. The father contributes either an X or Y chromosome, which determines the child's sex. This occurs at the moment of fertilization when the sperm carrying either an X (resulting in a female) or Y (resulting in a male) chromosome fertilizes the egg. Choices A, B, and C are incorrect because the presence of teratogens at the time of conception or ovulation does not determine the child's sex. While the sex chromosome received from the mother is important, it is the father's contribution that ultimately determines the child's sex.
2. The nurse is performing intake interviews at a psychiatric clinic. A female client with a known history of drug abuse reports that she had a heart attack four years ago. Use of which substance abuse places the client at the highest risk for myocardial infarction?
- A. Benzodiazepines
- B. Marijuana
- C. Methamphetamine
- D. Alcohol
Correct answer: C
Rationale: Methamphetamine use is strongly associated with cardiovascular risks, including myocardial infarction, due to its stimulant effects on the heart. Benzodiazepines (Choice A) are not typically associated with an increased risk of myocardial infarction. Marijuana (Choice B) is not commonly linked to heart attacks, though it can have other health effects. Alcohol (Choice D) abuse can lead to cardiovascular issues, but methamphetamine has a more direct and potent impact on the heart, making it the highest risk factor in this scenario.
3. A post-operative client is prescribed sequential compression devices (SCDs) while on bed rest. What is the primary purpose of this device?
- A. To prevent deep vein thrombosis (DVT).
- B. To improve circulation in the legs.
- C. To prevent pressure ulcers.
- D. To alleviate post-operative pain.
Correct answer: A
Rationale: The correct answer is A: 'To prevent deep vein thrombosis (DVT).' Sequential compression devices (SCDs) are primarily used to prevent deep vein thrombosis (DVT) by promoting blood flow in the legs and reducing venous stasis, which is a common risk for post-operative clients who are on bed rest. While SCDs do improve circulation in the legs indirectly, their primary purpose is DVT prevention. Preventing pressure ulcers is typically achieved through repositioning and support surfaces, not with SCDs, making choice C incorrect. SCDs are not used to alleviate post-operative pain, so choice D is also incorrect.
4. What is the main purpose of quality improvement in healthcare?
- A. To increase healthcare costs
- B. To improve patient outcomes
- C. To decrease patient satisfaction
- D. To increase hospital stays
Correct answer: B
Rationale: The main purpose of quality improvement in healthcare is to improve patient outcomes by enhancing the quality and safety of healthcare services. Choice A is incorrect because the goal is not to increase healthcare costs but to optimize resources and provide cost-effective care. Choice C is incorrect as the aim is to increase patient satisfaction through better outcomes. Choice D is incorrect as the objective is to reduce hospital stays by improving care efficiency and effectiveness.
5. A client who took a camping vacation two weeks ago in a country with a tropical climate comes to the clinic describing vague symptoms and diarrhea for the past week. Which finding is most important for the nurse to report to the HCP?
- A. Weakness and fatigue
- B. Intestinal cramping
- C. Weight loss
- D. Jaundiced sclera
Correct answer: D
Rationale: The most important finding to report to the healthcare provider is a jaundiced sclera. Jaundice suggests liver involvement, which can be a sign of a serious underlying condition. Weakness and fatigue, intestinal cramping, and weight loss are important symptoms, but jaundice indicates a more urgent issue that needs immediate attention.
