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 professional is preparing to administer magnesium sulfate 2 g/hr IV to a client who is in preterm labor. Available is 20 g of magnesium sulfate in 500 mL of dextrose 5% in water (D5W). How many mL/hr should the IV infusion pump be set to administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 60
• B. 30
• C. 50
• D. 80

Correct answer: C

Rationale: To administer magnesium sulfate 2 g/hr IV, the healthcare professional should set the IV infusion pump to administer 50 mL/hr. The calculation is as follows: 20 g / 500 mL = 2 g / X mL, X = 50 mL/hr. Choice A (60 mL/hr) is incorrect as it does not match the calculated rate. Choice B (30 mL/hr) is incorrect as it is half of the calculated rate. Choice D (80 mL/hr) is incorrect as it is higher than the calculated rate.

3. When reinforcing discharge teaching to the parents of a newborn regarding circumcision care, which statement made by a parent indicates an understanding of the teaching?

• A. The circumcision will heal within a couple of days.
• B. I should not remove the yellow mucus that will form.
• C. I will clean the penis with each diaper change.
• D. I will give him a tub bath within a couple of days.

Correct answer: C

Rationale: The correct answer is C because cleaning the penis with each diaper change is essential for preventing infection and promoting healing after circumcision. This practice helps maintain good hygiene and reduces the risk of complications. Removing the yellow mucus or giving a tub bath too soon can interfere with the healing process and increase the likelihood of infection. Choice A is incorrect because circumcision healing usually takes about a week or more, not just a couple of days. Choice B is incorrect because parents should gently clean the area, including removing any discharge or debris as part of proper care. Choice D is incorrect because tub baths should be avoided until the circumcision is fully healed to prevent infection.

4. A caregiver is being taught about bottle feeding a newborn. Which of the following statements by the caregiver indicates a need for further instruction?

• A. I will keep the baby's head elevated while feeding.
• B. I will allow the baby to burp several times during each feeding.
• C. I will tilt the bottle to prevent air from entering as the baby sucks.
• D. My baby will have soft, formed yellow stools.

Correct answer: C

Rationale: Tilting the bottle to prevent air from entering as the baby sucks can lead to the baby swallowing air, causing discomfort and potential issues like colic or gas. The correct way to bottle-feed a newborn is by ensuring that the nipple is always filled with milk to avoid air intake, which can lead to problems. Keeping the baby's head elevated while feeding helps prevent choking, allowing the baby to burp several times during each feeding helps release swallowed air, and soft, formed yellow stools indicate a healthy digestion process in newborns.

5. A client at 36 weeks of gestation is suspected of having placenta previa. Which of the following findings support this diagnosis?

• A. Painless red vaginal bleeding
• B. Increasing abdominal pain with a non-relaxed uterus
• C. Abdominal pain with scant red vaginal bleeding
• D. Intermittent abdominal pain following the passage of bloody mucus

Correct answer: A

Rationale: Painless red vaginal bleeding is a hallmark sign of placenta previa. In this condition, the placenta partially or completely covers the cervical opening, leading to painless, bright red bleeding due to the separation of the placenta from the uterine wall. Other types of bleeding, such as those associated with abdominal pain or mucus passage, are more indicative of conditions like placental abruption rather than placenta previa. Therefore, choices B, C, and D are incorrect as they describe findings more consistent with placental abruption rather than placenta previa.
