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. For newborns, the vastus lateralis muscle is the preferred site for intramuscular injections due to its size and well-developed muscle mass, ensuring proper absorption and minimizing the risk of injury to surrounding structures. Administering the vaccine into this muscle also helps improve vaccine efficacy. Choices B, C, and D are incorrect. Choice B, vigorously massaging the site, can cause discomfort, bruising, and potential tissue damage. Choice C, inserting the needle at a 45° angle, is not recommended for intramuscular injections as the needle should be inserted at a 90° angle to ensure proper delivery into the muscle. Choice D, using a 21-gauge needle, is not specific for newborns and can be too large for their small muscle mass, causing unnecessary pain and potential tissue damage.

A nurse is obtaining a 2-hr postprandial blood glucose from a client. Which of the following actions should the nurse take?
- A. Puncture the finger while still damp with antiseptic solution.
- B. Smear the blood onto the reagent strip.
- C. Hold the finger above the heart prior to puncture.
- D. Select the lateral side of the finger for puncture.
Correct Answer: D
Rationale: The correct answer is D: Select the lateral side of the finger for puncture. This is important because the lateral side has fewer nerve endings, making it less painful for the client. Additionally, it reduces the risk of injury to the nerves and blood vessels located on the other sides of the finger. Puncturing the finger while still damp with antiseptic solution (choice A) can dilute the blood sample and affect accuracy. Smearing the blood onto the reagent strip (choice B) may lead to inaccurate results due to improper application. Holding the finger above the heart prior to puncture (choice C) can increase blood flow and potentially affect the glucose level. Therefore, selecting the lateral side of the finger for puncture is the best practice for obtaining a 2-hr postprandial blood glucose sample.
A nurse is assessing a client who is 1 hr postpartum following a vaginal birth. The nurse notes that the client has excessive vaginal bleeding. Which of the following actions should the nurse take first?
- A. Massage the client's fundus.
- B. Administer oxytocin to the client.
- C. Empty the client’s bladder.
- D. Provide oxygen to the client via nonrebreather face mask.
Correct Answer: A
Rationale: The correct action for the nurse to take first is to massage the client's fundus. This is because excessive vaginal bleeding postpartum could indicate uterine atony, which is a common cause of postpartum hemorrhage. By massaging the fundus, the nurse can help stimulate uterine contractions and reduce bleeding. Administering oxytocin (choice B) may be necessary but massaging the fundus should be done first. Emptying the client's bladder (choice C) can also help, but addressing uterine atony is the priority. Providing oxygen (choice D) is not the immediate action needed for excessive vaginal bleeding.
A nurse is caring for a client who is in the second stage of labor and is experiencing a shoulder dystocia. The provider instructs the nurse to perform the McRoberts maneuver. Which of the following actions should the nurse take?
- A. Apply pressure to the client's fundus.
- B. Press firmly on the client’s suprapubic area.
- C. Move the client onto their hands and knees.
- D. Assist the client in pulling their knees toward their abdomen.
Correct Answer: D
Rationale: The correct answer is D: Assist the client in pulling their knees toward their abdomen. In shoulder dystocia, the McRoberts maneuver involves hyperflexing the mother's legs against her abdomen. This action helps to widen the pelvic outlet and reduce the angle of the pubic symphysis, facilitating the delivery of the infant's shoulder. Pressing on the fundus (A) does not address the shoulder dystocia issue. Pressing on the suprapubic area (B) may not provide the necessary assistance in this situation. Moving the client onto their hands and knees (C) does not facilitate the specific maneuver required. Therefore, assisting the client in pulling their knees toward their abdomen (D) is the correct action in this scenario.
A nurse is assessing a client who is 3 days postpartum. Which of the following findings should the nurse report to the provider?
- A. Cool, clammy skin
- B. Moderate lochia serosa
- C. Heart rate 89/min
- D. BP 120/70 mm Hg
Correct Answer: A
Rationale: The correct answer is A: Cool, clammy skin. This finding may indicate hypovolemic shock, a serious condition postpartum. The nurse should report this to the provider immediately for further evaluation and intervention. Choice B, moderate lochia serosa, is a normal finding 3 days postpartum. Choice C, heart rate 89/min, and choice D, BP 120/70 mm Hg, are within normal ranges for a postpartum client and do not require immediate reporting.
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. When a newborn is delivered with a nuchal cord (around the neck), it can cause pressure on the baby's face during delivery, leading to tiny broken blood vessels called petechiae. This is a common finding in newborns with nuchal cords due to the pressure exerted on the face. Telangiectatic nevi (A), periauricular papillomas (C), and erythema toxicum (D) are not typically associated with nuchal cords. Petechiae is the most likely finding in this scenario.
