1. Which preventive measure can be employed to decrease the risk of compartment syndrome?

• A. The administration of a potassium-sparing diuretic for heart failure
• B. A bivalve cast for a skeletal fracture
• C. A cerebral diuretic to decrease intracranial pressure after a head injury
• D. A chest tube to restore normal intrathoracic pressure after a pneumothorax

Correct answer: B

Rationale: The correct answer is B. A bivalve cast can help decrease the risk of compartment syndrome by providing space for swelling, thus preventing the build-up of pressure within the muscles. Choices A, C, and D are incorrect because they are not directly related to preventing compartment syndrome. Choice A is more focused on managing heart failure, choice C on reducing intracranial pressure, and choice D on restoring intrathoracic pressure after a pneumothorax, which are not relevant to preventing compartment syndrome.

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

• A. A patient fall
• B. The massive spread of pneumonia
• C. A computer hacking episode
• D. Unexpected staff absences due to illness

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.

3. Rotating injection sites when administering insulin prevents which of the following complications?

• A. Insulin edema
• B. Insulin lipodystrophy
• C. Insulin resistance
• D. Systemic allergic reactions

Correct answer: B

Rationale: Rotating injection sites when administering insulin helps prevent insulin lipodystrophy, which is the abnormal distribution of fat at injection sites. Insulin edema (choice A) is not prevented by rotating injection sites; it is characterized by swelling at the site of insulin injection due to increased capillary permeability. Insulin resistance (choice C) is a condition where the body's cells become less responsive to insulin, and rotating injection sites does not directly prevent this. Systemic allergic reactions (choice D) are not specifically prevented by rotating injection sites; they are related to an allergic response to insulin.

4. What does the mnemonic PERLA stand for in the assessment of the eyes?

• A. Pupils equally reactive to light and accommodation
• B. Patient eyes are equally recessed and responsive to light and acuity
• C. Patient eyes are equally responsive to light and acuity
• D. Pupils equally reactive to light and acuity

Correct answer: A

Rationale: The correct answer is A: 'Pupils equally reactive to light and accommodation.' PERLA is a mnemonic used in eye assessments to check for Pupils being equally reactive to Light and Accommodation. Choice B is incorrect as it includes irrelevant information about the eyes being recessed. Choice C is incorrect as it is missing the mention of pupils and accommodation. Choice D is incorrect as it misses the mention of accommodation.

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?

• A. ST depression
• B. Inverted T wave
• C. Prominent U wave
• D. Tall peaked T waves

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.
