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. During a client's active labor, a healthcare provider notes that the presenting part is at 0 station. What is the correct interpretation of this clinical finding?

• A. The fetal head is in the left occiput posterior position.
• B. The largest fetal diameter has passed through the pelvic outlet.
• C. The posterior fontanel is palpable.
• D. The lowermost portion of the fetus is at the level of the ischial spines.

Correct answer: D

Rationale: At 0 station, the lowermost portion of the fetus is at the level of the ischial spines, indicating that the presenting part of the baby has engaged in the pelvis. This position is a significant milestone in labor progress and suggests that the baby is descending into the birth canal for delivery. Choices A, B, and C are incorrect. Choice A refers to the fetal head position, choice B describes the largest fetal diameter passing through the pelvic outlet (which is not related to station), and choice C refers to the palpability of the posterior fontanel (which is not relevant to station in labor).

3. A nurse in a prenatal clinic is caring for a client who is at 7 weeks of gestation. The client reports urinary frequency and asks if this will continue until delivery. Which of the following responses should the nurse make?

• A. It's a minor inconvenience, which you should ignore.
• B. In most cases it only lasts until the 12th week, but it will continue if you have poor bladder tone.
• C. There is no way to predict how long it will last in each individual client.
• D. It occurs during the first trimester and near the end of the pregnancy.

Correct answer: D

Rationale: Urinary frequency is common during the first trimester and again at the end of pregnancy when the baby drops into the pelvis, putting pressure on the bladder.

4. A nurse is caring for a preterm newborn who is in an incubator to maintain a neutral thermal environment. The father of the newborn asks the nurse why this is necessary. Which of the following responses should the nurse make?

• A. Preterm newborns have a smaller body surface area than normal newborns.
• B. The added brown fat layer in a preterm newborn reduces his ability to generate heat.
• C. Preterm newborns lack adequate temperature control mechanisms.
• D. The heat in the incubator rapidly dries the sweat of preterm newborns.

Correct answer: C

Rationale: The correct answer is C because preterm newborns have immature temperature regulation mechanisms, making it difficult for them to maintain their body temperature. An incubator helps maintain a stable thermal environment. Choice A is incorrect as the body surface area is not the primary reason for needing an incubator. Choice B is incorrect because brown fat in preterm newborns actually helps generate heat. Choice D is incorrect as the purpose of the incubator is not to dry sweat but to regulate the newborn's temperature.

5. A client is scheduled for a maternal serum alpha-fetoprotein test at 15 weeks of gestation. The client asks the nurse about the purpose of this test. What explanation should the nurse provide?

• A. This test screens for neural tube defects and other developmental abnormalities in the fetus.
• B. It assesses various markers of fetal well-being.
• C. This test identifies an Rh incompatibility between the mother and fetus.
• D. It is a screening test for spinal defects in the fetus.

Correct answer: A

Rationale: The maternal serum alpha-fetoprotein (MSAFP) test is performed around 15-18 weeks of gestation to screen for neural tube defects and other developmental abnormalities in the fetus, not to assess fetal lung maturity, markers of fetal well-being, or Rh incompatibility between the mother and fetus. Choice A is the correct answer as it accurately reflects the purpose of the MSAFP test. Choices B, C, and D are incorrect because they do not align with the primary goal of this screening test.
