The nurse explains that prior to fertilization each cell is reduced from 46 chromosomes to 23 chromosomes. This is referred to as the __________ number.
- A. haploid
- B. DNA
- C. Chromoses
- D. Plastoderm
Correct Answer: A
Rationale: Prior to fertilization, each cell undergoes meiosis, reducing its chromosome count from 46 to 23. This reduction ensures genetic diversity and proper development of the embryo. The term 'haploid' refers to cells containing only one set of chromosomes.

The nurse is caring for a pregnant patient who is 35 weeks gestation and reports sharp abdominal pain and decreased fetal movement. What is the nurse's priority action?
- A. Encourage the patient to drink water and rest in a comfortable position.
- B. Call the healthcare provider immediately and prepare for further assessment.
- C. Monitor the fetal heart rate and perform a nonstress test.
- D. Ask the patient to lie on her left side and wait for symptoms to resolve.
Correct Answer: B
Rationale: The correct answer is B: Call the healthcare provider immediately and prepare for further assessment. This is the priority action because sharp abdominal pain and decreased fetal movement at 35 weeks gestation could indicate a serious complication such as placental abruption or fetal distress. Calling the healthcare provider promptly allows for timely intervention and assessment to ensure the safety of both the mother and the baby. Encouraging the patient to drink water and rest (choice A) may not address the underlying issue. Monitoring fetal heart rate and performing a nonstress test (choice C) may be important but not as immediate as contacting the healthcare provider. Asking the patient to lie on her left side and wait for symptoms to resolve (choice D) delays necessary medical evaluation and intervention.
A pregnant patient at 34 weeks gestation reports sudden swelling of the hands, feet, and face. What is the nurse's priority action?
- A. Monitor the patient's blood pressure and check for signs of preeclampsia.
- B. Encourage the patient to elevate the legs to reduce swelling.
- C. Administer diuretics as prescribed to reduce fluid retention.
- D. Instruct the patient to drink more water and reduce sodium intake.
Correct Answer: A
Rationale: The correct answer is A: Monitor the patient's blood pressure and check for signs of preeclampsia.
Rationale:
1. Sudden swelling of the hands, feet, and face in a pregnant patient at 34 weeks gestation can be a sign of preeclampsia.
2. Preeclampsia is a serious condition characterized by high blood pressure and protein in the urine, which can lead to complications for both the mother and the baby.
3. Monitoring the patient's blood pressure and checking for signs of preeclampsia is crucial for early detection and management of the condition.
4. Prompt intervention is necessary to prevent potential severe outcomes such as seizures, stroke, or organ damage.
Summary of Incorrect Choices:
B: Elevating the legs may provide temporary relief but does not address the underlying cause of the sudden swelling, which could be preeclampsia.
C: Administering diuretics without assessing the patient's blood pressure and ruling out
What does optimal nursing care after an amniocentesis include?
- A. Pushing fluids by mouth
- B. Monitoring uterine activity
- C. Placing the patient in a supine position for 2 hours
- D. Applying a pressure dressing to the puncture site
Correct Answer: B
Rationale: Monitoring uterine activity after an amniocentesis is important to detect any contractions that may indicate complications.
A nurse is caring for a postpartum person who is at risk for postpartum hemorrhage. What is the most important nursing action to reduce the risk?
- A. administer oxytocin
- B. administer IV fluids
- C. administer an epidural
- D. perform fundal massage
Correct Answer: B
Rationale: The correct answer is B: administer IV fluids. IV fluids help maintain adequate circulating volume, preventing hypovolemia which is a major risk factor for postpartum hemorrhage. This action supports blood pressure and perfusion to reduce the risk of excessive bleeding. Administering oxytocin (A) helps with uterine contraction but does not address the underlying issue of hypovolemia. Administering an epidural (C) is not directly related to preventing postpartum hemorrhage. Fundal massage (D) is important but not the most critical action in reducing the risk of postpartum hemorrhage.
The nurse asks a 31-week gestation client to lie on the examining table during a prenatal examination.
- A. Orthopneic.
- B. Lateral-recumbent.
- C. Sims'.
- D. Semi-Fowler’s.
Correct Answer: B
Rationale: The lateral-recumbent position reduces pressure on the inferior vena cava and is safer for pregnant women compared to other positions.
