1. What ECG changes should be monitored in a patient with hypokalemia?

A. Flattened T waves and prominent U waves
B. Elevated ST segments and wide QRS complexes
C. Tall T waves and flattened QRS complexes
D. Widened QRS complexes and decreased P wave amplitude

Correct answer: A

Rationale: The correct answer is A: Flattened T waves and prominent U waves. In hypokalemia, there is a decrease in potassium levels, which can lead to ECG changes such as flattened T waves and prominent U waves. These changes are classic findings associated with hypokalemia. Choices B (Elevated ST segments and wide QRS complexes), C (Tall T waves and flattened QRS complexes), and D (Widened QRS complexes and decreased P wave amplitude) are all incorrect. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia. Tall T waves and flattened QRS complexes, as well as widened QRS complexes and decreased P wave amplitude, do not represent the typical ECG changes seen in hypokalemia.

2. What are the expected symptoms in a patient with compartment syndrome?

A. Unrelieved pain, pallor, and pulselessness
B. Localized swelling and redness
C. Fever and swelling
D. Weakness and fatigue

Correct answer: A

Rationale: The correct answer is A: Unrelieved pain, pallor, and pulselessness. These symptoms are classic signs of compartment syndrome, which is a serious condition characterized by reduced circulation in a closed muscle compartment. The pain is typically severe and disproportionate to the injury, and if left untreated, it can lead to tissue damage and loss of function. Choices B, C, and D are incorrect because they do not represent the hallmark symptoms of compartment syndrome. Localized swelling and redness may be present but are not specific to this condition. Fever and swelling are more indicative of inflammation or infection, while weakness and fatigue are nonspecific and do not typically occur in isolation in compartment syndrome.

3. A nurse in a rural community center is providing education to a group of clients about first aid interventions for snake bites. Which of the following instructions should the nurse include in the teaching?

A. Apply an ice pack directly to the affected area
B. Immobilize the affected extremity with a splint
C. Place a tourniquet above and below the affected area
D. Elevate the affected extremity

Correct answer: B

Rationale: The correct answer is to immobilize the affected extremity with a splint. This helps to slow the spread of venom by limiting movement. Applying an ice pack directly to the affected area (Choice A) is not recommended for snake bites as it could exacerbate tissue damage. Placing a tourniquet above and below the affected area (Choice C) is also not advised as it can lead to further complications. Elevating the affected extremity (Choice D) is not recommended for snake bites; keeping it below the level of the heart is more appropriate to reduce venom spread.

4. When planning care for a patient with diabetes insipidus, what should the nurse include in the plan?

A. Monitor serum albumin levels
B. Avoid alcohol
C. Teach the patient to increase fluids
D. Increase exercise to reduce stress

Correct answer: B

Rationale: The correct answer is B: 'Avoid alcohol.' Alcohol consumption can exacerbate dehydration in patients with diabetes insipidus, so it is essential to advise them to avoid alcohol. Monitoring serum albumin levels (choice A) is not directly related to managing diabetes insipidus. Teaching the patient to increase fluids (choice C) is not recommended as it can worsen the condition by further diluting the urine. Increasing exercise to reduce stress (choice D) is not a primary intervention for managing diabetes insipidus.

5. What should be included in teaching for a patient with pre-dialysis end-stage kidney disease?

A. Limit phosphorus intake to 700 mg/day
B. Increase protein intake to 1g/kg/day
C. Increase sodium intake
D. Limit sodium to 1,500 mg/day

Correct answer: A

Rationale: The correct answer is to limit phosphorus intake to 700 mg/day for a patient with pre-dialysis end-stage kidney disease. Excessive phosphorus intake can lead to further complications in kidney disease, such as bone and cardiovascular issues. Choice B is incorrect as increasing protein intake can put additional stress on the kidneys due to the buildup of urea and other waste products. Choice C is incorrect because increasing sodium intake can worsen hypertension and fluid retention, common issues in kidney disease. Choice D is incorrect as limiting sodium intake is generally recommended in kidney disease to manage blood pressure and fluid balance.
