A nurse is administering a hepatitis B vaccine to a newborn. Which of the following actions should the nurse take?
- A. Administer the injection into the vastus lateralis muscle.
- B. Vigorously massage the site following the injection.
- C. Insert the needle at a 45° angle for injection.
- D. Use a 21-gauge needle for the injection.
Correct Answer: A
Rationale: The correct answer is A: Administer the injection into the vastus lateralis muscle. This is the recommended site for administering vaccines to newborns due to the large muscle mass, reducing the risk of injury to nerves and blood vessels. It also allows for proper absorption of the vaccine. Option B is incorrect as vigorous massage can lead to tissue damage and discomfort. Option C is incorrect as the needle should be inserted at a 90° angle for intramuscular injections. Option D is incorrect as a smaller gauge needle (typically 25-27 gauge) is recommended for newborns to minimize pain and tissue trauma.

A nurse is assessing a newborn who is 16 hr old. Which of the following findings should the nurse report to the provider?
- A. Substernal retractions
- B. Acrocyanosis
- C. Overlapping suture lines
- D. Head circumference 33 cm (13 in)
Correct Answer: A
Rationale: The correct answer is A: Substernal retractions. Substernal retractions in a newborn indicate respiratory distress and can be a sign of a serious issue such as respiratory distress syndrome. This finding requires immediate attention from the provider to assess and manage the newborn's respiratory status. Acrocyanosis (B) is a common finding in newborns and is not typically concerning. Overlapping suture lines (C) can be normal in newborns due to molding during birth. A head circumference of 33 cm (13 in) (D) falls within the normal range for a newborn and does not require immediate reporting.
A nurse is preparing to administer metronidazole 2 g PO to a client who has trichomoniasis. Available is metronidazole 250 mg tablets. How many tablets should the nurse administer?
- A. 8 tablets
- B. 4 Tablets
- C. 2 tablets
- D. 1 tablet
Correct Answer: A
Rationale: The correct answer is A: 8 tablets. To calculate the dose, divide the total dose by the dose per tablet. In this case, 2 g equals 2000 mg. Therefore, divide 2000 mg by 250 mg (dose per tablet), which equals 8 tablets. Each tablet contains 250 mg, so to reach the total dose of 2000 mg, the nurse needs to administer 8 tablets. Choice B (4 tablets) is incorrect because it would only provide 1000 mg, not the required 2000 mg. Choice C (2 tablets) would provide only 500 mg, not the required dose. Choice D (1 tablet) would provide only 250 mg, which is insufficient.
A nurse is caring for a client following an amniocentesis at 18 weeks of gestation. Which of the following findings should the nurse report to the provider as a potential complication?
- A. Increased fetal movement
- B. Leakage of fluid from the vagina
- C. Upper abdominal discomfort
- D. Urinary frequency
Correct Answer: B
Rationale: Correct Answer: B - Leakage of fluid from the vagina
Rationale: Following an amniocentesis at 18 weeks of gestation, leakage of fluid from the vagina could indicate a potential complication such as premature rupture of membranes. This complication could lead to preterm labor and pose a risk to both the mother and the fetus.
Summary of Other Choices:
A: Increased fetal movement - Normal fetal movement is expected following an amniocentesis and does not necessarily indicate a complication.
C: Upper abdominal discomfort - Common after an amniocentesis due to the needle insertion but usually resolves without major issues.
D: Urinary frequency - Not directly related to complications following an amniocentesis at 18 weeks gestation.
A nurse is performing an initial assessment of a newborn who was delivered with a nuchal cord. Which of the following clinical findings should the nurse expect?
- A. Telangiectatic nevi
- B. Facial petechiae
- C. Periauricular papillomas
- D. Erythema toxicum
Correct Answer: B
Rationale: The correct answer is B: Facial petechiae. A nuchal cord occurs when the umbilical cord is wrapped around the baby's neck at birth. This can cause pressure on the baby's blood vessels, leading to tiny red or purple spots on the face called petechiae. This finding indicates possible trauma during delivery. Telangiectatic nevi (choice A) are not typically associated with nuchal cords. Periauricular papillomas (choice C) are benign growths near the ear and are unrelated to nuchal cords. Erythema toxicum (choice D) is a common newborn rash that is not specifically linked to nuchal cords.
A nurse is caring for a client who is at 15 weeks of gestation, is Rh-negative, and has just had an amniocentesis. Which of the following interventions is the nurse's priority following the procedure?
- A. Check the client's temperature.
- B. Observe for uterine contractions.
- C. Administer Rho(D) immune globulin.
- D. Monitor the FHR.
Correct Answer: C
Rationale: The correct answer is C: Administer Rho(D) immune globulin. This is the priority intervention following an amniocentesis in an Rh-negative client at 15 weeks gestation to prevent Rh isoimmunization. Administering Rho(D) immune globulin helps prevent the mother's immune system from forming antibodies against Rh-positive fetal blood cells, which could lead to hemolytic disease in the newborn. Checking the client's temperature (A) is not the priority as there is no immediate risk related to the procedure. Observing for uterine contractions (B) is important but not the priority immediately post-procedure. Monitoring the FHR (D) is important but not the priority at this time.
