1. Which of the following is considered an internal disaster?

Correct answer: C

Rationale: A computer hacking episode is considered an internal disaster as it disrupts the internal operations of the healthcare facility, compromising data security and potentially impacting patient care. Choices A, B, and D do not directly relate to internal disasters in a healthcare setting. A patient fall is a patient safety issue, the massive spread of pneumonia is a public health concern, and unexpected staff absences due to illness may affect staffing levels but are not typically classified as internal disasters.

2. A clinical instructor teaches a class for the public about diabetes mellitus. Which individual does the nurse assess as being at highest risk for developing diabetes?

Correct answer: C

Rationale: The 42-year-old client who is 50 pounds overweight is at the highest risk for developing diabetes. Excess weight is a significant risk factor for diabetes as it can lead to insulin resistance and metabolic abnormalities. Choices A, B, and D are also risk factors for diabetes, but being overweight has a stronger association with the development of the condition compared to lack of exercise, excessive alcohol consumption, or smoking.

3. Which statement about glaucoma is true and accurate?

Correct answer: A

Rationale: The correct answer is A: 'Acute angle-closure glaucoma is an ocular emergency.' Acute angle-closure glaucoma is indeed considered an ocular emergency that requires immediate attention to prevent vision loss. Choice B is incorrect because acute angle-closure glaucoma commonly presents with symptoms like severe eye pain, headache, blurred vision, and halos around lights. Choice C is incorrect as these symptoms are more indicative of acute angle-closure glaucoma rather than primary open-angle glaucoma. Choice D is incorrect since bubbles are not typically used to protect the retina from glaucoma; treatment usually involves medications, laser therapy, or surgery to manage intraocular pressure.

4. Which patient is at greatest risk for papilledema?

Correct answer: D

Rationale: An adolescent with a closed head injury is at the highest risk for papilledema due to increased intracranial pressure. Papilledema is often a consequence of elevated intracranial pressure, which can occur in conditions like head trauma. Choices A, B, and C do not directly correlate with an increased risk of papilledema compared to a closed head injury, which is more likely to lead to elevated intracranial pressure and subsequent papilledema.

5. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?

Correct answer: D

Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.
