1. Which pathologic condition is described as 'increased intraocular pressure of the eye'?

• A. Detached Retina
• B. Fovea Centralis
• C. Presbyopia
• D. Glaucoma

Correct answer: D

Rationale: The correct answer is Glaucoma. Glaucoma is a condition characterized by increased intraocular pressure in the eye, which can lead to optic nerve damage, vision loss, and blindness if left untreated. Detached Retina (A), Fovea Centralis (B), and Presbyopia (C) are not conditions associated with increased intraocular pressure like Glaucoma. Detached Retina is a separation of the retina from its underlying tissue, Fovea Centralis is a part of the retina responsible for sharp central vision, and Presbyopia is an age-related condition affecting near vision due to the loss of flexibility in the eye's lens.

2. A nurse is educating a patient about bimatoprost (Lumigan) eyedrops for the treatment of Glaucoma. Which of the following indicates that the patient has a correct understanding of the expected outcomes following treatment?

• A. "I should be experiencing less blurriness in my central field of vision"
• B. "This medication won't help my vision at all, but will keep it from getting worse."
• C. "My peripheral vision should be increasing back to its normal state, but will take a few weeks to do so."
• D. "This medication will help my eye restor intraocular fluid and increase intraocular pressure"

Correct answer: B

Rationale: Glaucoma cannot be cured, just treated. Treatment revolves around preventing further deterioration.

3. The healthcare provider is reviewing the lab results of a patient who has presented in the Emergency Room. The lab results show that the BNP (B-type Natriuretic Peptide) value is 615 pg/ml. What would the healthcare provider take as the priority action?

• A. Call for a cardiac evaluation and implement appropriate measures
• B. Check the patient's oxygen saturation
• C. Inform the physician about the elevated BNP level
• D. Encourage the patient to limit physical activity

Correct answer: B

Rationale: An elevated BNP level is indicative of decreased cardiac output, suggesting potential heart failure. In this scenario, the priority action is to check the patient's oxygen saturation. Oxygen saturation assessment is crucial to ensure adequate oxygenation and respiratory function, which is essential in managing cardiac conditions. Calling for a cardiac evaluation and implementing appropriate measures may be necessary but is not the immediate priority without assessing oxygen saturation. Informing the physician about the elevated BNP level can be important for further management but is not the immediate action needed in this situation. Encouraging the patient to limit physical activity might be a consideration later but is not the priority action when dealing with a potential cardiac emergency.

4. The healthcare provider is managing a 20 lbs (9 kg) 6-month-old with a 3-day history of diarrhea, occasional vomiting, and fever. Peripheral intravenous therapy has been initiated, with 5% dextrose in 0.33% normal saline with 20 mEq of potassium per liter infusing at 35 ml/hr. Which finding should be immediately reported to the healthcare provider?

• A. 3 episodes of vomiting in 1 hour.
• B. Periodic crying and irritability.
• C. Vigorous sucking on a pacifier.
• D. No measurable voiding in 4 hours.

Correct answer: D

Rationale: The critical finding that should be reported immediately to the healthcare provider is 'No measurable voiding in 4 hours.' This finding raises concerns about possible hyperkalemia, which can result from continued potassium administration and a decrease in urinary output. Hyperkalemia can lead to serious complications, including cardiac arrhythmias. The management of acute hyperkalemia involves interventions such as administering calcium to protect the heart, shifting potassium into cells, and enhancing potassium elimination from the body. The other choices do not indicate an urgent issue that requires immediate attention. Three episodes of vomiting in 1 hour can be concerning but may not be as immediately critical as the risk of hyperkalemia. Periodic crying and irritability are common in infants and may not indicate a severe complication. Vigorous sucking on a pacifier is a normal behavior in infants and does not signal a medical emergency.

5. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

• A. 60 microdrops/minute
• B. 20 microdrops/minute
• C. 30 microdrops/minute
• D. 40 microdrops/minute

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.
