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. While caring for a newborn undergoing phototherapy to treat hyperbilirubinemia, which of the following actions should the nurse take?

• A. Cover the newborn's eyes with an opaque eye mask while under the phototherapy light.
• B. Keep the newborn in a shirt while under the phototherapy light.
• C. Apply a light moisturizing lotion to the newborn's skin.
• D. Turn and reposition the newborn every 4 hours while undergoing phototherapy.

Correct answer: A

Rationale: It is crucial to cover the newborn's eyes with an opaque eye mask to prevent damage to the retinas and corneas from the phototherapy light. The eyes are particularly sensitive to the light used in phototherapy, and shielding them helps protect the newborn's delicate eyes from potential harm. Choice B is incorrect because the newborn should be undressed to maximize skin exposure to the phototherapy light. Choice C is incorrect because lotions or oils can interfere with the effectiveness of phototherapy. Choice D is incorrect because the newborn should be kept as still as possible to maximize exposure to the light.

3. A client is postpartum and has idiopathic thrombocytopenic purpura (ITP). Which of the following findings should the nurse expect?

• A. Decreased platelet count
• B. Increased erythrocyte sedimentation rate (ESR)
• C. Decreased megakaryocytes
• D. Increased WBC

Correct answer: A

Rationale: Idiopathic thrombocytopenic purpura (ITP) is characterized by an autoimmune response that leads to a decreased platelet count. This condition increases the risk of bleeding due to the low platelet levels. Monitoring the platelet count is crucial in managing ITP, as it helps determine the risk of bleeding and guides treatment decisions. Therefore, the correct finding to expect in a client with ITP is a decreased platelet count. Choice B, an increased erythrocyte sedimentation rate (ESR), is not typically associated with ITP. Choice C, decreased megakaryocytes, may be seen in conditions like aplastic anemia but are not a typical finding in ITP. Choice D, an increased white blood cell count (WBC), is not a characteristic feature of ITP.

4. A client who is at 7 weeks of gestation is experiencing nausea and vomiting in the morning. Which of the following information should the nurse include?

• A. Eat crackers or plain toast before getting out of bed
• B. Awaken during the night to eat a snack
• C. Skip breakfast and eat lunch after nausea has subsided
• D. Eat a large evening meal

Correct answer: A

Rationale: During early pregnancy, nausea and vomiting in the morning are common symptoms. Eating crackers or plain toast before getting out of bed can help manage morning nausea by stabilizing blood sugar levels. This simple and easily digestible snack can alleviate symptoms by providing some sustenance to the stomach before fully waking up and moving around. Choices B, C, and D are incorrect. Waking up during the night to eat a snack may disrupt sleep patterns, skipping breakfast can worsen symptoms by allowing the stomach to remain empty for longer periods, and eating a large evening meal may exacerbate morning nausea due to increased stomach contents.

5. 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.
