Management of thalassaemia includes:

Correct Answer: C

Rationale: In the management of thalassaemia, the correct option is C) Bone marrow transplant. Thalassaemia is a genetic blood disorder characterized by abnormal hemoglobin production. A bone marrow transplant offers a potential cure by replacing the faulty bone marrow with healthy stem cells that can produce normal hemoglobin. A) Whole blood transfusions are used to provide symptomatic relief by replenishing red blood cells, but they do not cure thalassaemia. B) Pneumovax is a vaccine used to prevent pneumococcal infections, which are not directly related to the management of thalassaemia. D) Penicillin V prophylaxis may be prescribed to prevent infections in individuals with thalassaemia, but it is not a curative treatment. Educationally, understanding the management of thalassaemia is crucial for pediatric nurses caring for children with this condition. Knowing the appropriate interventions, such as bone marrow transplant, can help nurses provide comprehensive and effective care to improve outcomes for their patients. It is essential for nurses to be knowledgeable about the different treatment options available to provide safe and evidence-based care for children with thalassaemia.

Correct Answer: A

Rationale: In the context of pediatric nursing and cardiovascular disorders, understanding neurodegenerative diseases is crucial as they can impact a child's overall health and well-being. In this question, the correct answer is A) Niemann-Pick disease, a neurodegenerative disorder characterized by the abnormal accumulation of lipids in cells, leading to progressive neurological deterioration. Option B) Metachromatic leukodystrophy is a metabolic disorder that affects the nervous system primarily, causing demyelination. While it is a neurodegenerative disease, it is not specifically related to cardiovascular disorders, making it an incorrect choice for this question. Option C) Leigh's encephalopathy is a rare, inherited neurometabolic disorder that affects the central nervous system. While it is a neurodegenerative disease, it does not fall under the category of cardiovascular disorders, making it an incorrect choice in this context. Option D) Canavan disease is a rare, inherited disorder that damages the ability of nerve cells to send and receive messages. Similar to the other incorrect options, Canavan disease is a neurodegenerative disorder but is not directly associated with cardiovascular disorders, making it an incorrect choice for this question. Educationally, knowing the specific neurodegenerative diseases associated with pediatric patients with cardiovascular disorders helps nurses provide comprehensive care and anticipate potential complications. Understanding the distinctions between these diseases enhances clinical reasoning skills and improves patient outcomes through early recognition and intervention.

Correct Answer: D

Rationale: In this scenario, a VII nerve injury at the exit from the stylomastoid foramen results in facial nerve paralysis. The correct answer, D) Inability to open the ipsilateral eye, is explained by the fact that the facial nerve innervates the muscles responsible for eyelid closure. This paralysis causes the inability to close the eye, not open it. Option A) Loss of sensation over the vallecula is incorrect because sensation over the vallecula is innervated by the glossopharyngeal nerve (IX), not the facial nerve (VII). Option B) Loss of taste over the anterior third of the tongue is incorrect as taste sensation over the anterior two-thirds of the tongue is carried by the chorda tympani nerve, a branch of the facial nerve. Option C) Increased responsiveness to loud noises is unrelated to a VII nerve injury and is not a typical consequence of facial nerve dysfunction. Educationally, understanding the specific functions of cranial nerves and their areas of innervation is crucial in clinical practice, especially in pediatric nursing where accurate assessment and interpretation of symptoms are vital for providing appropriate care. This knowledge helps in differentiating between various cranial nerve lesions and determining the appropriate interventions for the patient's condition.

Correct Answer: D

Rationale: In homo cystinuria, the correct answer is D) Dislocation of lens is a feature. This is because homo cystinuria is a genetic disorder that results in the abnormal accumulation of homocysteine in the body. One of the key clinical manifestations of this condition is the dislocation of the lens in the eye, known as ectopia lentis. This occurs due to the deposition of homocysteine in the ocular tissues, leading to structural changes that result in lens dislocation. Option A is incorrect because homocysteine accumulates systemically, not just proximal to the enzyme defect. Option B is incorrect as osteoporosis is not a recognized feature of homo cystinuria. Option C is incorrect as oral contraceptive pills with estrogens are not contraindicated specifically in homo cystinuria. Educationally, understanding the clinical manifestations of genetic disorders like homo cystinuria is crucial for nurses caring for pediatric patients with cardiovascular disorders. Recognizing the signs and symptoms allows for early intervention and management to prevent complications such as lens dislocation. Nurses need to be knowledgeable about the unique features of each disorder to provide holistic care to their patients.

Correct Answer: A

Rationale: The correct answer is A) Median nerve supplies all thenar muscles except adductor pollicis. Explanation: Innervation of the hand is a crucial concept in understanding neurological deficits and clinical manifestations. The median nerve innervates the thenar muscles - abductor pollicis brevis, flexor pollicis brevis, opponens pollicis - responsible for thumb movement and opposition. The adductor pollicis is an exception as it is innervated by the ulnar nerve. Understanding this innervation pattern is essential for assessing hand function and diagnosing nerve injuries accurately. Let's analyze why the other options are incorrect: B) The sensory supply to the dorsal surface of the medial two digits is via the radial nerve. This statement is incorrect. The sensory supply to the dorsal surface of the medial two digits is actually provided by the ulnar nerve, not the radial nerve. This misconception can lead to errors in localizing nerve injuries and assessing sensory deficits. C) In ulnar nerve damage at the elbow, there is sensory loss over the medial aspect of the forearm proximal to the wrist. This option is incorrect. Ulnar nerve damage at the elbow typically results in sensory loss in the ulnar distribution of the hand and the palmar aspect of the medial one and a half fingers, not the forearm proximal to the wrist. Understanding the specific sensory distribution helps in diagnosing and managing nerve injuries effectively. D) Radial nerve provides the sensory innervation to the terminal areas of the dorsal surfaces of the lateral three digits. This statement is incorrect. The radial nerve primarily supplies the dorsal aspect of the hand, but it innervates the dorsal surfaces of the lateral three and a half digits, not just the lateral three digits. Knowing the precise innervation territories aids in differentiating nerve lesions and planning appropriate interventions. Educational Context: Understanding the innervation of the hand is fundamental in clinical practice, especially in assessing nerve injuries, localizing deficits, and providing optimal patient care. Nurses and healthcare providers must grasp these concepts to conduct accurate neurologic assessments, diagnose conditions like carpal tunnel syndrome or nerve injuries, and implement appropriate interventions. Mastery of hand innervation enhances clinical reasoning skills, promotes patient safety, and improves overall quality of care in pediatric nursing and beyond.
