Correct Answer: D

Rationale: Correct Answer: D - Administering oxygen Rationale: 1. Oxygen is crucial in acute myocardial infarction to improve oxygenation and reduce myocardial workload. 2. Administering oxygen helps alleviate ischemia and prevents further damage. 3. Prioritizing oxygenation before pain medication or assessment ensures immediate intervention for the patient's well-being. Summary of other choices: A: Administering pain medication - Important for comfort but not the priority in acute myocardial infarction. B: Performing a head-to-toe assessment - Necessary but not as urgent as ensuring oxygenation. C: Establishing an intravenous line - Helpful but not as critical as administering oxygen in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Turn the client every two hours. This action helps prevent pressure ulcers by relieving pressure on specific areas of the body. Turning the client redistributes pressure, promotes circulation, and reduces the risk of tissue damage. It is a crucial part of pressure ulcer prevention in immobile or bedridden patients. Increasing protein intake (B) may aid in wound healing but does not directly prevent pressure ulcers. Encouraging rest (C) may not address the root cause of pressure ulcers. Applying dressings to wounds (D) is a treatment for existing ulcers, not prevention.

Correct Answer: D

Rationale: The correct answer is D: Huntington's chorea. Huntington's chorea is a genetic disorder characterized by involuntary, writhing, and twisting movements of the face and limbs, known as chorea. This is due to degeneration of certain brain cells. Epilepsy (A) involves seizures, not specific movements. Parkinson's (B) is characterized by tremors and rigidity, not chorea. Multiple sclerosis (C) affects the central nervous system, causing a variety of symptoms, but not typically chorea.

Correct Answer: C

Rationale: The correct answer is C: 12. At 18 months, a child should have 12 teeth, which include 8 incisors and 4 molars. This is because children typically start teething around 6 months, with the lower central incisors coming first. By 18 months, they should have all 8 incisors and usually the first set of molars. Options A, B, and D are incorrect because they do not align with the typical dental development timeline for children. Having only 6, 8, or 16 teeth at 18 months would indicate a delay or abnormality in dental growth.

Correct Answer: C

Rationale: The correct answer is C because validating the data by asking a colleague to listen to the breath sounds helps to ensure accuracy and reliability. It allows for a second opinion to confirm the nurse's assessment and prevents any potential misinterpretation. This collaborative approach promotes patient safety and quality care. Choices A and D are incorrect as they do not address the immediate need for validation and may delay appropriate intervention. Choice B is also incorrect as it does not ensure the accuracy of the assessment and may lead to miscommunication or incorrect treatment decisions.
