A pregnant patient at 32 weeks gestation reports swelling in the feet and hands. What should the nurse do first?
- A. Monitor the patient's blood pressure and assess for signs of preeclampsia.
- B. Encourage the patient to elevate her feet and rest for 30 minutes.
- C. Recommend that the patient drink more water and reduce sodium intake.
- D. Assess the patient for signs of a blood clot or deep vein thrombosis.
Correct Answer: A
Rationale: The correct answer is A: Monitor the patient's blood pressure and assess for signs of preeclampsia. At 32 weeks gestation, swelling in the feet and hands can be a sign of preeclampsia, a serious condition characterized by high blood pressure and protein in the urine. Monitoring blood pressure is crucial as elevated blood pressure is a key indicator of preeclampsia. Assessing for other signs of preeclampsia such as headache, visual disturbances, or upper abdominal pain is important for early detection and management. Prompt intervention is necessary to prevent complications for both the mother and the baby.
Choices B, C, and D are incorrect because while elevation of feet, rest, hydration, and reducing sodium intake are important in managing mild swelling during pregnancy, in this case, the priority is to rule out preeclampsia which can lead to severe complications if left untreated. Assessing for blood clots or deep vein thrombosis is also important but
A pregnant patient at 34 weeks gestation is experiencing heartburn. Which of the following is the nurse's most appropriate recommendation?
- A. Take antacids regularly to manage heartburn.
- B. Lie down immediately after meals to aid digestion.
- C. Eat small, frequent meals and avoid spicy or greasy foods.
- D. Avoid drinking fluids during meals to prevent heartburn.
Correct Answer: C
Rationale: Rationale: Option C is the most appropriate recommendation because eating small, frequent meals and avoiding spicy or greasy foods can help reduce heartburn during pregnancy. Large meals can exacerbate heartburn, so smaller meals are easier to digest. Spicy and greasy foods can also trigger heartburn. Options A, B, and D are not recommended for managing heartburn during pregnancy. Taking antacids regularly can lead to potential risks for the developing fetus. Lying down immediately after meals can worsen heartburn due to increased intra-abdominal pressure, and avoiding fluids during meals may not necessarily prevent heartburn.
A pregnant patient at 26 weeks gestation reports pain in the lower abdomen and back. What should the nurse do first?
- A. Encourage the patient to rest and monitor for changes in symptoms.
- B. Perform a pelvic exam to assess for possible cervical dilation.
- C. Administer pain medication to relieve the discomfort.
- D. Assess the patient's blood pressure and check for signs of preeclampsia.
Correct Answer: A
Rationale: The correct answer is A: Encourage the patient to rest and monitor for changes in symptoms. At 26 weeks gestation, lower abdominal and back pain could indicate preterm labor. The first step is to have the patient rest to reduce uterine activity. Monitoring for changes in symptoms is crucial to assess if the pain is worsening and if there are any signs of preterm labor. Performing a pelvic exam (B) could potentially stimulate contractions and should be avoided unless absolutely necessary. Administering pain medication (C) does not address the underlying cause and could mask symptoms. Assessing blood pressure for signs of preeclampsia (D) is important but not the first priority in this scenario.
