The healthcare professional is developing a teaching plan for a child who is to have their cast removed. What instruction would the professional most likely include?

Correct Answer: C

Rationale: Soaking the area in warm water is the most appropriate instruction for a child who is having their cast removed. This method helps to gently remove dead skin without causing irritation. Applying petroleum jelly to dry skin (Choice A) is not recommended as it may not effectively aid in the removal of dead skin. Rubbing the skin vigorously (Choice B) can lead to skin irritation and should be avoided. Washing the skin with diluted peroxide and water (Choice D) may be too harsh, causing unnecessary irritation to the skin post-cast removal.

Correct Answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs in response to chronic hypoxia, leading the body to increase red blood cell production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect that results in reduced oxygen levels in the blood, the body compensates by producing more red blood cells. Choice A is incorrect as low tissue oxygen needs would not trigger polycythemia. Choice C, diminished iron levels, is not the cause of polycythemia in this case. Choice D, hypertrophic cardiac muscle, is unrelated to the pathophysiology of polycythemia in tetralogy of Fallot.

Correct Answer: B

Rationale: When an adolescent with type 1 diabetes experiences an insulin reaction, it is essential to quickly raise their blood sugar levels. Buying a soda and a hamburger to eat is the best choice in this situation as it provides a fast-acting source of sugar to counteract hypoglycemia. Calling parents immediately may cause a delay in receiving appropriate treatment. Administering insulin would further lower blood sugar levels, worsening the situation. Leaving the arena and resting would not address the immediate need to raise blood sugar levels.

Correct Answer: A

Rationale: The correct answer is to monitor for signs of infection. When a child is undergoing chemotherapy, their immune system is compromised, making them more susceptible to infections. Monitoring for signs of infection is crucial to promptly identify and treat any potential infections. Choices B, C, and D are incorrect because although monitoring for bleeding, dehydration, and pain are important aspects of care, the priority for a child receiving chemotherapy is to prevent and detect infections due to their increased vulnerability.

Correct Answer: C

Rationale: In this scenario, the nurse failed to report or document the slow respiratory rate of the infant, which later led to severe respiratory distress. It is crucial to understand that any vital signs outside the expected range in an infant should be documented and reported promptly. This documentation is vital for monitoring the infant's condition, identifying potential issues, and ensuring timely intervention if needed. Choices A, B, and D are incorrect because they downplay the significance of abnormal vital signs and fail to emphasize the importance of documentation and reporting in infant care.

Correct Answer: A

Rationale: Initiating intravenous saline solution is the initial priority in managing diabetic ketoacidosis to address dehydration and electrolyte imbalances. Administering insulin without addressing dehydration first can lead to potential complications. While monitoring cardiac status and oxygen saturation are important, addressing the fluid and electrolyte imbalances takes precedence in the management of DKA.

Correct Answer: C

Rationale: When a dysrhythmia is suspected, an important nursing responsibility is to count the apical pulse for 1 full minute and then compare this rate with the radial pulse rate. This method helps in identifying dysrhythmias as it allows for a direct comparison of the heart's rhythm at two different pulse points. Ordering an immediate electrocardiogram (Choice A) may be necessary but should not be the first step. Counting the radial pulse multiple times (Choice B) is not as accurate as comparing rates directly. Having someone else take the radial pulse simultaneously (Choice D) may introduce errors and inconsistencies in the measurement.

Correct Answer: A

Rationale: Infection is the greatest risk for an infant with exstrophy of the bladder due to the exposure of the bladder and surrounding tissues. The exposed bladder increases the risk of infection as it lacks the protective covering of the skin. Dehydration (Choice B) may occur but is not the greatest risk compared to infection. Urinary retention (Choice C) is less likely due to the nature of the condition. Intestinal obstruction (Choice D) is not directly associated with exstrophy of the bladder.

Correct Answer: C

Rationale: Low-set ears with lobe creases are often associated with genetic disorders, such as Down syndrome, and can indicate underlying chromosomal abnormalities. This physical characteristic is a common feature seen in various genetic syndromes. The other choices, including feeding problems, weight and height measurements, and motor skills, are not typically specific indicators of genetic disorders in the absence of other associated features.
