Correct Answer: B

Rationale: Step 1: Immunotherapy injections can cause allergic reactions. Step 2: Monitoring post-injection is crucial to detect and manage any potential adverse reactions promptly. Step 3: Staying in the clinic for 30 minutes allows for immediate intervention if needed. Step 4: This ensures patient safety and reduces the risk of severe reactions. Summary: A: Epinephrine is not typically given before immunotherapy injections. C: Therapeutic response may take longer than 3 months to show. D: Immunotherapy is usually given via subcutaneous route, not intravenous.

Correct Answer: C

Rationale: The correct answer is C because African-American ethnicity and previous cesarean birth are established risk factors for placenta previa due to the potential for scarring and abnormal placental implantation. Male fetus does not influence the risk. Asian-American ethnicity and previous preterm birth are not significant risk factors. European-American ethnicity and previous spontaneous abortion are also not associated with an increased risk of placenta previa.

Correct Answer: B

Rationale: Correct Answer: B - Use of a raised toilet seat Rationale: A raised toilet seat helps the patient with Parkinson's disease by providing additional height, making it easier for them to transition from sitting to standing. This aids in improving mobility and reducing the risk of falls. Furthermore, the raised seat can also promote proper positioning for bowel elimination, making the process more comfortable and effective. Incorrect Choices: A: Using a bedpan does not address the issue of transitioning from sitting to standing, nor does it aid in improving bowel elimination for the patient. C: Sitting quietly on the toilet every 2 hours may not directly address the physical challenges the patient is facing in transitioning from sitting to standing. D: Following the outlined bowel program is important, but it does not specifically address the physical support needed to transition from sitting to standing for a patient with Parkinson's disease.

Correct Answer: C

Rationale: The correct answer is C because folic acid is crucial in preventing neural tube defects and anemia in the developing fetus. The nurse should teach the expectant mother about the importance of taking folic acid supplements before and during pregnancy. Folic acid is essential for proper cell division and growth, reducing the risk of birth defects. Choice A is incorrect because calcium intake is important throughout pregnancy, not just in the first trimester. Choice B is incorrect as protein intake should be adequate to support maternal and fetal growth, not decreased. Choice D is incorrect as excessive intake of vitamins and minerals can be harmful to the mother and the baby. In summary, the expectant mother should be educated on the importance of folic acid supplementation to prevent birth defects and anemia, while also ensuring a balanced diet with all essential nutrients.

Correct Answer: A

Rationale: The correct answer is A: Teach the patient how to self-cath the pouch. In a continent urinary reservoir, patients need to catheterize the pouch several times a day. This is essential for emptying the urine from the pouch as the ileocecal valve creates a one-way valve. Teaching the patient how to self-catheterize ensures proper and timely drainage, preventing complications like urinary retention. Self-catheterization also empowers the patient to take an active role in managing their continence. Summary of other choices: B: Kegel exercises are ineffective for a patient with a continent urinary reservoir as they do not address the need for catheterization. C: Changing the collection pouch is not the primary action needed for a continent urinary reservoir. Catheterization is essential for drainage. D: The Valsalva technique is not appropriate for voiding in a continent urinary reservoir. Catheterization is the recommended method for emptying the pouch.
