Nursing Elites

1. Which statement about glaucoma is true and accurate?

• A. Acute angle-closure glaucoma is an ocular emergency.
• B. Acute angle-closure glaucoma leads to the loss of peripheral vision and tunnel vision.
• C. Primary open-angle glaucoma leads to eye pain, nausea, and vomiting, blurry vision, and halos.
• D. Bubbles are implanted to protect the retina from glaucoma.

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.

2. What is the normal sodium level in the body?

• A. 135 to 145 milliequivalents per liter.
• B. 3 to 5 milliequivalents per liter.
• C. 135 to 145 microequivalents per liter.
• D. 3 to 5 microequivalents per liter.

Correct answer: A

Rationale: The correct answer is A: 135 to 145 milliequivalents per liter. The normal range for sodium levels in the body is expressed in milliequivalents per liter, not microequivalents. Choice B and D provide a significantly lower range which is not within the normal values for sodium. Choice C incorrectly states 'microequivalents' instead of the correct unit 'milliequivalents'. Therefore, A is the correct answer.

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. A patient is admitted to the emergency department with hypovolemia. Which IV solution should the nurse anticipate administering?

• A. 3% sodium chloride
• B. 10% dextrose in water
• C. 0.45% sodium chloride
• D. Lactated Ringer's solution

Correct answer: D

Rationale: Lactated Ringer's solution is the most suitable IV solution for a patient with hypovolemia. It is a balanced crystalloid solution containing electrolytes such as sodium, chloride, potassium, calcium, and lactate, which closely resemble the body's natural fluids. This solution helps to restore intravascular volume and electrolyte balance in hypovolemic patients. Choice A, 3% sodium chloride, is a hypertonic solution used for specific situations like severe hyponatremia or cerebral edema, not typically for hypovolemia. Choice B, 10% dextrose in water, is a hypertonic solution primarily used for providing calories and free water, not for volume expansion. Choice C, 0.45% sodium chloride, is a hypotonic solution used for conditions like hypernatremia or as maintenance fluid, not for hypovolemia.

5. How many calories per kilogram does an average full-term infant require when the infant is around 1-2 months old?

• A. 140 calories per kilogram per day
• B. 120 calories per kilogram per day
• C. 100 calories per kilogram per day
• D. 160 calories per kilogram per day

Correct answer: B

Rationale: An average full-term infant requires about 120 calories per kilogram per day at 1-2 months old. This amount is essential for their growth and development during this critical stage. Choices A, C, and D are incorrect as they provide calorie amounts that are either too high or too low for an average full-term infant at 1-2 months old, which could potentially lead to health issues or inadequate nutrition.
