The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarctation 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?

Correct Answer: B

Rationale: The findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.

Correct Answer: B

Rationale: The correct priority action for the nurse is to start an IV infusion of normal saline. The client's presentation with lethargy, fruity-smelling breath, and high blood glucose level indicates diabetic ketoacidosis (DKA). IV fluids are essential to correct dehydration and help stabilize the client's condition. Checking for ketones in the urine is important, but fluid replacement takes precedence to address the immediate risk of dehydration and electrolyte imbalances. Administering insulin is also a crucial intervention for DKA, but fluid resuscitation should first be initiated.

Correct Answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario. The nurse obtained an apical heart rate of 128 bpm, which is within the expected range for a 2-year-old child. Therefore, there is no immediate concern to withhold the scheduled dose of digoxin. Determining the pulse deficit is not necessary as the heart rate is appropriate. Calculating the safe dose range is not needed as the current dose is within the therapeutic range. Reviewing the serum digoxin level may be indicated later for monitoring but is not urgent based on the heart rate assessment. Administering the scheduled dose of digoxin is the correct action at this time.

Correct Answer: B

Rationale: Increased urine output is a reliable indicator that hydration status is improving. While alertness and playfulness are positive signs, increased urine output directly reflects improved hydration. Stable vital signs are important but may not directly indicate hydration status. Tolerating small amounts of oral fluids is a good sign but may not be as direct an indicator as increased urine output.

Correct Answer: B

Rationale: The priority action for the nurse when a client with meningitis presents with a severe headache and photophobia is to place the client in a dark, quiet room. This intervention helps reduce stimuli that can exacerbate symptoms such as headache and photophobia. Creating a calm environment can provide relief and promote comfort for the client while also supporting their recovery. Administering pain medication may be necessary but ensuring a suitable environment takes precedence. Notifying the healthcare provider is important but is not the immediate priority. Encouraging rest is beneficial, but creating an appropriate environment to alleviate symptoms is the initial essential step.

Correct Answer: D

Rationale: Encouraging the child to use the bathroom before bed is a helpful recommendation to prevent nighttime bedwetting. Bedwetting can sometimes reoccur due to stress or other factors, and ensuring the child empties their bladder before sleeping may reduce the likelihood of bedwetting episodes. Choice A is incorrect because while bedwetting is common in children, it is essential to provide practical solutions rather than just reassurance. Choice B is not the best option for a child who has recently started bedwetting again after being dry, as it may not address the underlying cause. Choice C is inappropriate and harmful as punishing the child for bedwetting can lead to psychological distress and worsen the situation.

Correct Answer: C

Rationale: The correct answer is C. Applying warm compresses to a sprained ankle within the first 24 hours is incorrect as it can increase swelling and inflammation. Instead, cold compresses are recommended to help reduce swelling and pain. Option A, keeping the leg elevated, helps in reducing swelling. Option B, wrapping the ankle in an elastic bandage, provides support. Option D, using an ice pack in intervals, is effective in reducing swelling and pain. Therefore, the statement about applying warm compresses indicates the need for further instruction.

Correct Answer: C

Rationale: When assessing a child with acute glomerulonephritis (AGN), a common trigger to expect in the nursing history is a recent strep throat infection. AGN can be triggered by a streptococcal infection, leading to the deposition of immune complexes in the glomeruli. This finding is crucial as it helps identify a potential cause for the development of AGN in the child. Choices A, B, and D are incorrect as high blood cholesterol levels, increased thirst and urination, and recent DPT immunization are not directly associated with triggering acute glomerulonephritis in children.

Correct Answer: A

Rationale: The correct intervention for a child with Kawasaki disease, presenting with irritability and skin peeling, is to place the child in a quiet environment. This helps reduce environmental stimuli, calming the child and aiding in managing the symptoms associated with the disease. Choice B is incorrect as addressing food preferences is not the priority in this situation. Choice C is incorrect as the focus should be on the child's immediate needs. Choice D is incorrect as applying lotion is not the first-line intervention for Kawasaki disease symptoms.
