Nursing Elites

1. A healthcare provider is preparing to administer vitamin K by IM injection to a newborn. The medication should be administered into which of the following muscles?

• A. Vastus lateralis
• B. Ventrogluteal
• C. Dorsogluteal
• D. Deltoid

Correct answer: A

Rationale: Vitamin K is typically administered in the vastus lateralis muscle of a newborn to prevent bleeding disorders. The vastus lateralis muscle is the preferred site for IM injections in infants due to its size and accessibility, allowing for easy and safe administration. The ventrogluteal and dorsogluteal sites are more commonly used in adults due to better muscle mass and less risk of injury to nearby structures. The deltoid muscle is typically used for older children and adults for IM injections, as it is a well-developed muscle suitable for injections in these populations.

2. A client is being cared for 2 hours after a spontaneous vaginal birth and has saturated two perineal pads with blood in a 30-minute period. Which of the following is the priority nursing intervention at this time?

• A. Palpate the client's uterine fundus.
• B. Assist the client to a bedpan to urinate.
• C. Prepare to administer oxytocic medication.
• D. Increase the client's fluid intake.

Correct answer: A

Rationale: The priority nursing intervention in this situation is to palpate the client's uterine fundus. A boggy uterus that is not well contracted may indicate uterine atony, which can lead to postpartum hemorrhage. Palpating the fundus and massaging it if it is boggy helps to promote contractions and reduce bleeding, making it the most critical intervention to address the potential underlying issue. Assisting the client to a bedpan to urinate, preparing to administer oxytocic medication, or increasing the client's fluid intake are not the immediate priorities in this scenario compared to assessing and addressing the uterine fundus status.

3. A client who is pregnant states that her last menstrual period was April 1st. What is the client's estimated date of delivery?

• A. January 8
• B. January 15
• C. February 8
• D. February 15

Correct answer: A

Rationale: To calculate the estimated date of delivery, add 7 days to the first day of the last menstrual period (April 1st), which gives April 8th. Then, count forward 9 months from April 8th, leading to January 8th as the estimated date of delivery. Choice A is correct. Choice B is incorrect because it is exactly 9 months from the last menstrual period without accounting for the additional 7 days. Choices C and D are incorrect as they fall in February, which is beyond the 9-month period from the last menstrual period.

4. When advising a woman considering pregnancy on nutritional needs to reduce the risk of giving birth to a newborn with a neural tube defect, what information should the nurse include?

• A. Limit alcohol consumption.
• B. Increase intake of iron-rich foods.
• C. Consume foods fortified with folic acid.
• D. Avoid foods containing aspartame.

Correct answer: C

Rationale: The correct answer is C: Consume foods fortified with folic acid. Folic acid plays a crucial role in preventing neural tube defects. It is advised to consume foods fortified with folic acid or take a supplement containing at least 400 micrograms of folic acid daily. This nutrient is essential for the developing fetus and can significantly reduce the risk of neural tube defects when taken before and during early pregnancy. Choices A, B, and D are incorrect. While limiting alcohol consumption is important during pregnancy, it is not directly related to reducing the risk of neural tube defects. Increasing intake of iron-rich foods is essential for preventing anemia but is not specifically linked to neural tube defects. Avoiding foods containing aspartame is generally recommended, but it is not directly related to reducing the risk of neural tube defects.

5. During preterm labor, a client is scheduled for an amniocentesis. The nurse should review which of the following tests to assess fetal lung maturity?

• A. Alpha-fetoprotein (AFP)
• B. Lecithin/sphingomyelin (L/S) ratio
• C. Kleihauer-Betke test
• D. Indirect Coombs' test

Correct answer: B

Rationale: The Lecithin/sphingomyelin (L/S) ratio is a test used to evaluate fetal lung maturity. An L/S ratio greater than 2:1 indicates fetal lung maturity. This test helps in determining the risk of respiratory distress syndrome in the newborn. Alpha-fetoprotein (AFP) is used in screening for neural tube defects, not for assessing lung maturity. The Kleihauer-Betke test is used to detect fetal-maternal hemorrhage, not fetal lung maturity. The Indirect Coombs' test is used to identify the presence of antibodies in the mother's blood that could attack fetal red blood cells, not for assessing lung maturity.
