HESI Maternity 55 Questions
1. What is the primary role of meiosis in the production of sperm and ova?
- A. To reduce the chromosome number by half
- B. To increase the chromosome number
- C. To create identical copies of chromosomes
- D. To repair damaged chromosomes
Correct answer: A
Rationale: The correct answer is A. Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the formation of sperm and ova. Choice B is incorrect because meiosis does not increase the chromosome number. Choice C is incorrect because meiosis creates genetically diverse gametes, not identical copies of chromosomes. Choice D is incorrect because meiosis does not primarily function to repair damaged chromosomes.
2. The clinician is assessing a client with a Stage 2 skin ulcer. Which of the following treatments is most effective to promote healing?
- A. Covering the wound with a dry dressing
- B. Using hydrogen peroxide soaks
- C. Leaving the area open to dry
- D. Applying a hydrocolloid or foam dressing
Correct answer: D
Rationale: Applying a hydrocolloid or foam dressing is the most effective treatment to promote healing for a Stage 2 skin ulcer. These dressings create a moist environment that supports healing and prevents further tissue damage. Option A (covering the wound with a dry dressing) can lead to drying out the wound bed, hindering healing. Option B (using hydrogen peroxide soaks) can be too harsh and may damage the surrounding healthy tissue. Option C (leaving the area open to dry) can delay healing as it does not provide the necessary moist environment for optimal wound healing.
3. A client with a history of seizures is receiving phenytoin (Dilantin). The nurse should monitor the client for which of the following side effects?
- A. Hypertension
- B. Hyperglycemia
- C. Gingival hyperplasia
- D. Hypokalemia
Correct answer: C
Rationale: The correct answer is C: Gingival hyperplasia. Phenytoin can cause gingival hyperplasia, characterized by an overgrowth of gum tissue. It is important for the nurse to monitor the client for this side effect as it can lead to oral health issues. Choices A, B, and D are incorrect. Phenytoin does not typically cause hypertension, hyperglycemia, or hypokalemia as common side effects.
4. A client with a peptic ulcer is scheduled for a vagotomy and pyloroplasty. The nurse explains that the purpose of this surgery is to:
- A. Increase acid secretion
- B. Reduce acid secretion
- C. Promote gastric emptying
- D. Remove the ulcerated area
Correct answer: B
Rationale: The correct answer is B: "Reduce acid secretion." Vagotomy is performed to reduce acid secretion by cutting the vagus nerve, which stimulates acid production. Choices A, C, and D are incorrect. A vagotomy does not increase acid secretion, promote gastric emptying, or remove the ulcerated area. It specifically aims to decrease acid production to help in the healing of peptic ulcers.
5. A child with a diagnosis of sickle cell anemia is experiencing a vaso-occlusive crisis. What is the most important nursing intervention?
- A. Administering oxygen
- B. Administering pain medication
- C. Monitoring fluid intake
- D. Encouraging physical activity
Correct answer: B
Rationale: During a vaso-occlusive crisis in sickle cell anemia, the most important nursing intervention is to administer pain medication. Pain management is crucial in alleviating the intense pain experienced by the patient. Administering oxygen (Choice A) may be necessary in some cases to improve oxygenation, but pain relief takes precedence during a vaso-occlusive crisis. Monitoring fluid intake (Choice C) is important for hydration but is not the priority during a crisis. Encouraging physical activity (Choice D) is contraindicated during a vaso-occlusive crisis as it can exacerbate pain and tissue damage.
