Nursing Elites

1. A healthcare provider is assessing a newborn who has a coarctation of the aorta. Which of the following should the provider recognize as a clinical manifestation of coarctation of the aorta?

• A. Increased blood pressure in the arms with decreased blood pressure in the legs
• B. Decreased blood pressure in the arms with increased blood pressure in the legs
• C. Increased blood pressure in both the arms and the legs
• D. Decreased blood pressure in both the arms and the legs

Correct answer: A

Rationale: The correct answer is increased blood pressure in the arms with decreased blood pressure in the legs. Coarctation of the aorta is a congenital heart defect characterized by a narrowing of the aorta, leading to increased blood pressure in the upper extremities and decreased blood pressure in the lower extremities due to decreased blood flow beyond the narrowing. Choice B is incorrect because coarctation of the aorta does not lead to increased blood pressure in the legs. Choice C is incorrect because increased blood pressure in both the arms and legs is not a typical manifestation of coarctation of the aorta. Choice D is incorrect because decreased blood pressure in both the arms and legs is not characteristic of coarctation of the aorta.

2. A healthcare provider is assisting with the care for a client who has a prescription for magnesium sulfate. The provider should recognize that which of the following are contraindications for the use of this medication? (Select all that apply)

• A. Fetal distress
• B. Cervical dilation greater than 6 cm
• C. Vaginal bleeding
• D. All of the Above

Correct answer: D

Rationale: The correct answer is D, 'All of the Above.' Magnesium sulfate should not be used in cases of fetal distress, vaginal bleeding, or cervical dilation greater than 6 cm. These conditions can be exacerbated by the administration of magnesium sulfate, leading to further complications for the client. Choice A, fetal distress, is a contraindication because magnesium sulfate can further affect the fetal heart rate. Choice B, cervical dilation greater than 6 cm, is a contraindication as magnesium sulfate can potentially suppress uterine contractions, prolonging labor. Choice C, vaginal bleeding, is a contraindication as magnesium sulfate can further increase bleeding tendencies.

3. During active labor, a nurse notes tachycardia on the external fetal monitor tracing. Which of the following conditions should the nurse identify as a potential cause of the heart rate?

• A. Maternal fever
• B. Fetal heart failure
• C. Maternal hypoglycemia
• D. Fetal head compression

Correct answer: A

Rationale: Maternal fever can lead to fetal tachycardia due to the transmission of maternal fever to the fetus. This can result in an increased fetal heart rate, making it the correct potential cause in this scenario. Fetal heart failure (choice B) would typically present with bradycardia rather than tachycardia, making it an incorrect choice. Maternal hypoglycemia (choice C) is more likely to cause fetal distress rather than tachycardia. Fetal head compression (choice D) may lead to decelerations in the fetal heart rate pattern, but not necessarily tachycardia.

4. When assessing newborn reflexes, what action should be taken to elicit the Moro reflex?

• A. Perform a sharp hand clap near the infant.
• B. Hold the newborn vertically allowing one foot to touch the table surface.
• C. Place a finger at the base of the newborn's toes.
• D. Turn the newborn's head quickly to one side.

Correct answer: A

Rationale: The correct answer is A: Perform a sharp hand clap near the infant. The Moro reflex, also known as the startle reflex, is elicited by a sudden stimuli such as a sharp hand clap near the infant. This reflex is characterized by the infant's arms extending and then flexing with a distinctive 'startle' motion. It is a normal and expected reflex in newborns, typically disappearing by 3-6 months of age. Choices B, C, and D are incorrect because they do not elicit the Moro reflex; holding the newborn vertically (choice B) or placing a finger at the base of the newborn's toes (choice C) are associated with other reflexes, while turning the newborn's head quickly to one side (choice D) is related to the tonic neck reflex.

5. 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.
