Reproductive System Exam Questions
1. What is amniocentesis used to detect?
- A. Sexually transmitted diseases
- B. Presence of certain genetic disorders
- C. Causes of infertility
- D. Presence of pneumonia germs
Correct answer: B
Rationale: Amniocentesis is a prenatal test used to detect certain genetic disorders in a developing fetus. It involves collecting a small sample of the amniotic fluid surrounding the fetus and analyzing the genetic material present in the cells. This test is not used to detect sexually transmitted diseases, causes of infertility, or the presence of pneumonia germs. Therefore, the correct answer is B.
2. An older client who had a subtotal parathyroidectomy is preparing for discharge. What finding requires immediate provider notification?
- A. Afebrile with a normal pulse.
- B. No bowel movement since surgery.
- C. No appetite for breakfast.
- D. A positive Chvostek's sign.
Correct answer: D
Rationale: A positive Chvostek's sign indicates hypocalcemia, a complication after parathyroid surgery that requires immediate attention. This sign is manifested by facial muscle twitching when the facial nerve in front of the ear is tapped, indicating neuromuscular irritability due to low calcium levels. Afebrile with a normal pulse (Choice A) is a normal finding and does not require immediate notification. No bowel movement since surgery (Choice B) is common postoperatively due to anesthesia effects and pain medications and usually resolves within a few days; it does not require immediate notification unless accompanied by other concerning symptoms. No appetite for breakfast (Choice C) is a common postoperative finding and does not require immediate notification unless it persists and leads to dehydration or malnutrition.
3. Which of the following lab results is most indicative of dehydration?
- A. Low sodium levels.
- B. Elevated creatinine levels.
- C. Low potassium levels.
- D. High blood glucose levels.
Correct answer: B
Rationale: Elevated creatinine levels are indicative of dehydration because when the body is dehydrated, the kidneys concentrate urine to preserve fluid, leading to higher levels of creatinine. Low sodium levels (Choice A) can be seen in conditions like hyponatremia but are not specific to dehydration. Low potassium levels (Choice C) are more commonly associated with conditions like hypokalemia. High blood glucose levels (Choice D) are typically seen in diabetes and are not specific indicators of dehydration.
4. Blood for arterial blood gas determinations is drawn from a client with pneumonia, and testing reveals a pH of 7.45, PCO2 of 30 mm Hg, and HCO3 of 19 mEq/L. The nurse interprets these results as indicative of:
- A. Compensated metabolic acidosis
- B. Compensated respiratory alkalosis
- C. Uncompensated metabolic alkalosis
- D. Uncompensated respiratory acidosis
Correct answer: B
Rationale: The correct answer is 'Compensated respiratory alkalosis.' In this case, the client's pH is within the normal range (7.35-7.45), indicating compensation. The low PCO2 (30 mm Hg) suggests respiratory alkalosis, while the low HCO3 (19 mEq/L) is also consistent with a compensatory response. Therefore, the client has a primary respiratory alkalosis that is being compensated for by metabolic acidosis. Choices A, C, and D are incorrect because they do not fit the pattern of the given blood gas values, which indicate respiratory alkalosis with metabolic compensation.
5. A male infant with a 2-day history of fever and diarrhea is brought to the clinic by his mother, who tells the nurse that the child refuses to drink anything. The nurse determines that the child has a weak cry with no tears. Which intervention is most important to implement?
- A. Provide a bottle of electrolyte solution.
- B. Infuse normal saline intravenously.
- C. Administer an antipyretic rectally.
- D. Apply an external cooling blanket.
Correct answer: B
Rationale: Infusing normal saline intravenously is crucial to treat dehydration caused by fever and diarrhea. In this scenario, the infant's weak cry with no tears indicates severe dehydration, necessitating rapid fluid replacement via intravenous normal saline to restore fluid balance and prevent complications.
