Correct Answer: A

Rationale: The correct answer is 'Loss of consciousness.' While parents should report any concerning observations, they need to call the healthcare provider immediately if the infant experiences a loss of consciousness. This change in alertness may indicate anoxia, which can be life-threatening. Tetralogy of Fallot is a congenital heart defect characterized by four main features: pulmonic stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy. Surgery for Tetralogy of Fallot may be delayed or done in stages. Reporting loss of consciousness is crucial due to the potential seriousness of the condition. Feeding problems, poor weight gain, and fatigue with crying are important issues but do not require immediate reporting like loss of consciousness does.

Correct Answer: C

Rationale: A prickling sensation in the right hand is indicative of compartment syndrome, a serious condition that can lead to tissue damage and impaired circulation. Immediate attention is required to prevent complications. Capillary refill of 3 seconds, warm and normally colored skin, and slight swelling of fingers are expected findings after a closed reduction and casting. These findings do not typically indicate a critical issue and can be managed with routine monitoring.

Correct Answer: C

Rationale: The correct answer is nephrotoxicity. Calcium disodium edetate, used in chelation therapy for lead poisoning, can lead to kidney toxicity. This is an important side effect to monitor in patients undergoing this treatment. Choices A, B, and D are incorrect. Neurotoxicity, hepatomegaly, and ototoxicity are not typically associated with calcium disodium edetate therapy for lead poisoning.

Correct Answer: A

Rationale: The correct answer is 'Cereal.' The guidelines of the American Academy of Pediatrics recommend introducing one new food at a time, starting with strained cereal. Cereal is often recommended as a first solid food for infants due to its soft texture and iron-fortified properties, which are important for the baby's development. Eggs and meat are common allergenic foods and are usually introduced later. Juice is not recommended for infants under 1 year old due to its high sugar content and lack of nutritional value compared to whole fruits.

Correct Answer: A

Rationale: Oculogyric crisis is a known side effect of antipsychotic medications like Haloperidol (Haldol) and is characterized by involuntary upward deviation of the eyes. This condition can be distressing to both the client and their family. Tardive dyskinesia (Choice B) is a different side effect characterized by repetitive, involuntary movements, especially of the face and tongue, which can occur with long-term antipsychotic use. Nystagmus (Choice C) is an involuntary eye movement that is rhythmic and can occur for various reasons but is not specific to Haloperidol use. Dysphagia (Choice D) refers to difficulty swallowing and is not typically associated with the use of Haloperidol.
