A pregnant patient at 28 weeks gestation reports lightheadedness and fainting when standing up. What is the most likely cause of these symptoms?
- A. Dehydration and electrolyte imbalance
- B. Increased blood volume and decreased blood pressure
- C. Iron-deficiency anemia
- D. Hyperglycemia from gestational diabetes
Correct Answer: B
Rationale: The correct answer is B: Increased blood volume and decreased blood pressure. At 28 weeks gestation, the pregnant patient's blood volume significantly increases to support the developing fetus, causing a relative decrease in blood pressure when standing up (orthostatic hypotension). This can lead to lightheadedness and fainting. Dehydration and electrolyte imbalance (choice A) can contribute to these symptoms but are less likely in a pregnant patient. Iron-deficiency anemia (choice C) can cause similar symptoms but is less common at 28 weeks gestation. Hyperglycemia from gestational diabetes (choice D) typically presents with other symptoms like excessive thirst and urination, rather than lightheadedness and fainting.
A nurse is caring for a postpartum person who is at risk for deep vein thrombosis (DVT). What is the most appropriate nursing intervention?
- A. Encourage ambulation
- B. Apply compression stockings
- C. Administer low-molecular-weight heparin
- D. Monitor for signs of edema
Correct Answer: B
Rationale: The correct answer is B: Apply compression stockings. This intervention is appropriate for a postpartum person at risk for DVT as it helps promote circulation and prevent blood clots by applying pressure to the legs. Compression stockings are a safe and non-invasive method to reduce the risk of DVT. Encouraging ambulation (choice A) is important but may not be feasible immediately postpartum. Administering low-molecular-weight heparin (choice C) would require a prescription and may not be the first-line intervention. Monitoring for signs of edema (choice D) is important but does not directly address the prevention of DVT like compression stockings do.
A pregnant woman is scheduled to undergo chorionic villus sampling (CVS) based on genetic family history. Which medication does the nurse anticipate will be administered?
- A. Magnesium sulfate
- B. Prostaglandin suppository
- C. RhoGAM if the patient is Rh-negative
- D. Betamethasone
Correct Answer: C
Rationale: Rh-negative women undergoing CVS require RhoGAM to prevent Rh sensitization.
A client asks the nurse what was meant when the physician told her she had a positive Chadwick’s sign. Which of the following information about the finding would be appropriate for the nurse to convey at this time?
- A. It is a purplish stretch mark on your abdomen.
- B. It means that you are having heart palpitations.
- C. It is a bluish coloration of your cervix and vagina.
- D. It means the doctor heard abnormal sounds when you breathed in.
Correct Answer: C
Rationale: Chadwick’s sign is a bluish coloration of the cervix and vagina due to increased blood flow, which is a common early sign of pregnancy.
