Nursing Elites

1. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

• A. The aortic semilunar valve obstructs blood flow into the systemic circulation
• B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
• C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
• D. An opening in the atrial septum causes a murmur due to a turbulent left-to-right shunt

Correct answer: B

Rationale: The correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.

2. The nurse is caring for a 10-year-old child who is scheduled for surgery to repair a fractured femur. The child’s parent expresses concern about the child being afraid of the surgery. What is the nurse’s best response?

• A. Children at this age are usually not afraid of surgery
• B. It’s normal for your child to feel scared. Let’s talk about what to expect
• C. You should talk to the surgeon about your child’s fear
• D. Don’t worry, your child will be fine

Correct answer: B

Rationale: Acknowledging the child’s fear and providing information about what to expect can help alleviate anxiety.

3. The healthcare provider is preparing a teaching plan for the parents of a 6-month-old infant with GERD. What instruction should the healthcare provider include when teaching the parents measures to promote adequate nutrition?

• A. Alternate glucose water with formula
• B. Mix the formula with rice cereal
• C. Add multivitamins with iron to the formula
• D. Use water to dilute the formula

Correct answer: B

Rationale: The correct instruction for promoting adequate nutrition in a 6-month-old infant with GERD is to mix the formula with rice cereal. This thickens the feed, reducing the risk of reflux, aiding in proper nutrition, and minimizing GERD symptoms. Choices A, C, and D are incorrect. Alternating glucose water with formula, adding multivitamins with iron to the formula, or diluting the formula with water are not recommended measures for promoting adequate nutrition in infants with GERD.

4. The healthcare provider plans to administer 10 mcg/kg of digoxin elixir as a loading dose to a child who weighs 55 pounds. Digoxin is available as an elixir of 50 mcg/ml. How many milliliters of the digoxin elixir should the healthcare provider administer to this child?

• A. 5 ml
• B. 10 ml
• C. 15 ml
• D. 20 ml

Correct answer: A

Rationale: To calculate the dose, first, convert the child's weight to kilograms by dividing 55 pounds by 2.2, which equals approximately 25 kg. Then, multiply the weight by the dose (10 mcg/kg) to get the total dose needed, which is 250 mcg. Next, divide the total dose by the concentration of the elixir (50 mcg/ml) to determine the volume needed, which is 5 ml. Therefore, the correct dose is 5 ml based on the child's weight and the concentration of the elixir.

5. The mother of a 9-month-old, diagnosed with respiratory syncytial virus (RSV) yesterday, calls the clinic to inquire if it will be all right to take her infant to the first birthday party of a friend's child the following day. What response should the nurse provide this mother?

• A. The child will no longer be contagious, so no need to take any further precautions.
• B. Ensure there are no children under the age of 6 months around the infected child.
• C. The child can be around other children but should wear a mask at all times.
• D. Do not expose other children to RSV. It is highly contagious even without direct contact.

Correct answer: D

Rationale: The correct answer is D. RSV is highly contagious, even without direct contact. It is important to prevent the spread of the virus to other children, so the infected child should not attend the birthday party to avoid exposing other children to RSV. This is crucial to protect the health of other children who may be more vulnerable to the virus. Choices A, B, and C are incorrect. Choice A is incorrect as RSV remains contagious for a period of time, and precautions should be taken to prevent its spread. Choice B is incorrect because the age limit specified is not a reliable measure to prevent transmission. Choice C is incorrect as wearing a mask may not be sufficient to prevent the spread of RSV in a social setting like a birthday party.
