1. During a vaso-occlusive crisis in sickle cell anemia, what action is crucial for a nurse to take?

• A. Administer meperidine for pain.
• B. Apply cold compresses to the child's joints.
• C. Limit the child's fluid intake.
• D. Maintain bed rest for the child.

Correct answer: D

Rationale: During a vaso-occlusive crisis in sickle cell anemia, maintaining bed rest is crucial to reduce oxygen consumption and alleviate pain. Movement can worsen the crisis by increasing sickling of red blood cells, leading to further tissue damage and pain. Bed rest helps to improve blood flow, reduce pain, and promote healing. Administering meperidine for pain (Choice A) is not recommended due to the risk of normeperidine accumulation and potential neurotoxicity. Applying cold compresses (Choice B) may cause vasoconstriction, worsening the vaso-occlusive crisis. Limiting fluid intake (Choice C) is not appropriate as adequate hydration is essential to prevent dehydration and maintain blood flow.

2. A 9-month-old infant who is not sitting independently has been diagnosed with ataxic cerebral palsy (CP). Which clinical manifestations would the nurse expect to see in the baby?

• A. Hypotonia and muscle instability
• B. Hypertonia and persistence of primitive reflexes
• C. Tremors and exaggerated posturing
• D. Hemiplegia and hypertonia

Correct answer: A

Rationale: In ataxic cerebral palsy, the characteristic features include hypotonia (low muscle tone) and muscle instability. These manifestations contribute to the infant's difficulty in achieving independent sitting. Hypertonia (increased muscle tone) and persistence of primitive reflexes, as mentioned in option B, are more commonly associated with other types of cerebral palsy like spastic CP. Tremors and exaggerated posturing (option C) are not typical features of ataxic CP. Hemiplegia (paralysis of one side of the body) and hypertonia (increased muscle tone) mentioned in option D are more commonly seen in other types of cerebral palsy, such as spastic CP.

3. A patient taking isotretinoin (Accutane) for acne vulgaris. Which statement indicates that the patient teaching has been effective?

• A. I should use a reliable form of birth control.
• B. I will stop taking the drug if my skin is dry.
• C. It is important to increase intake of vitamin A.
• D. I do not need to use sunblock while taking Accutane.

Correct answer: A

Rationale: The correct answer is A. Isotretinoin is highly teratogenic, which means it can cause birth defects. Therefore, it is crucial for patients, especially females of childbearing potential, to use effective forms of birth control to prevent pregnancy while taking this medication. This is a key component of patient teaching to ensure the safe use of isotretinoin. Choice B is incorrect because discontinuing isotretinoin abruptly can lead to a flare-up of acne. Choice C is incorrect because increasing vitamin A intake can be harmful due to the risk of hypervitaminosis A. Choice D is incorrect because isotretinoin makes the skin more sensitive to sunlight, so sunblock is essential to prevent sunburn and skin damage.

4. What is the goal of pharmacologic therapy in the treatment of Parkinson�s disease?

• A. To increase the amount of acetylcholine at the pre-synaptic neurons
• B. To reduce the amount of dopamine available in the substantia nigra
• C. To balance cholinergic and dopaminergic activity in the brain
• D. To block dopamine receptors in pre-synaptic and post-synaptic neurons

Correct answer: C

Rationale: Parkinson�s disease results from a decrease in dopaminergic (inhibitory) activity, leaving an imbalance with too much cholinergic (excitatory) activity. With an increase in dopamine, the neurotransmitter activity becomes more balanced, and symptoms are controlled.

5. What is functional behavior analysis?

• A. Systematic observation of behavior
• B. Standardized assessment
• C. Multiple choice examination
• D. Parent-teacher questionnaire

Correct answer: A

Rationale: Functional behavior analysis involves systematically observing behavior to understand its function and context. It focuses on identifying the antecedents and consequences that maintain or influence behavior. This systematic observation helps in determining patterns, triggers, and maintaining factors of behavior. Standardized assessments (choice B) involve using specific tools or tests to measure a person's performance or behavior but do not focus on observation. Multiple choice examinations (choice C) and parent-teacher questionnaires (choice D) are not synonymous with functional behavior analysis as they do not involve direct observation of behavior for analysis.
