Nursing Elites

1. The healthcare provider calculates the IV flow rate for a patient receiving lactated Ringer's solution. The patient needs to receive 2000mL of Lactated Ringer's over 36 hours. The IV infusion set has a drop factor of 15 drops per milliliter. How many drops per minute should the healthcare provider set the IV to deliver?

• A. 8
• B. 10
• C. 14
• D. 18

Correct answer: C

Rationale: To determine the drops per minute, we use the formula Drops Per Minute = (Milliliters x Drop Factor) / Time in Minutes. In this case, Drops Per Minute = (2000mL x 15 drops/mL) / (36 hours x 60 minutes/hour) = 30000 / 2160 = 13.89 (approximately 14). Therefore, the correct answer is 14 drops per minute. Choice A (8), Choice B (10), and Choice D (18) are incorrect as they do not correctly calculate the drops per minute based on the given information.

2. A 45-year-old woman is prescribed ropinirole (Requip) for Parkinson's Disease. The patient is living at home with her daughter. The nurse is most concerned about which side effect of ropinirole?

• A. Slurred speech
• B. Sudden dizziness
• C. Mask-like facial expression
• D. Stooped posture

Correct answer: B

Rationale: The correct answer is 'Sudden dizziness.' Dizziness and orthostatic hypotension are serious adverse effects of ropinirole that can lead to an increased risk of falls. Ropinirole belongs to the drug class of dopamine agonists, which mimic dopamine in the brain (Parkinson's Disease is characterized by a lack of dopamine). 'Slurred speech' is not a common side effect of ropinirole. 'Mask-like facial expression' and 'Stooped posture' are more associated with the progression of Parkinson's Disease itself rather than a side effect of ropinirole.

3. A patient is admitted to the emergency department complaining of sudden onset shortness of breath and is diagnosed with a possible pulmonary embolus. How should the nurse prepare the patient for diagnostic testing to confirm the diagnosis?

• A. Start an IV so contrast media may be given
• B. Ensure that the patient has been NPO for at least 6 hours.
• C. Inform radiology that a radioactive glucose preparation is needed
• D. Instruct the patient to undress to the waist and remove any metal objects

Correct answer: A

Rationale: For diagnosing pulmonary emboli, spiral computed tomography (CT) scans are commonly used, and contrast media may be given intravenously (IV) during the scan to enhance visualization of blood vessels. Chest x-rays are not typically diagnostic for pulmonary embolism. When preparing for a chest x-ray, the patient needs to undress and remove any metal objects. Bronchoscopy is used for examining the bronchial tree, not for assessing vascular changes, and the patient should be NPO 6 to 12 hours before the procedure. Positron emission tomography (PET) scans are primarily used to detect malignancies, and a radioactive glucose preparation is utilized for this purpose.

4. The nurse reviews the record of a child who is suspected to have glomerulonephritis. Which statement by the child's parent should the nurse expect that is associated with this diagnosis?

• A. ''His pediatrician said his kidneys are working well.''
• B. ''I noticed his urine was the color of cola lately.''
• C. ''I'm so glad they didn't find any protein in his urine.''
• D. ''The nurse who admitted my child said his blood pressure was low.''

Correct answer: B

Rationale: Glomerulonephritis refers to a group of kidney disorders characterized by inflammatory injury in the glomerulus. Gross hematuria, resulting in dark, smoky, cola-colored, or brown-colored urine, is a classic symptom of glomerulonephritis. Blood urea nitrogen levels and serum creatinine levels may be elevated, indicating that kidney function is compromised. A mild to moderate elevation in protein in the urine is associated with glomerulonephritis. Hypertension is also common because of fluid volume overload secondary to the kidneys not working properly. Therefore, the parent's statement about noticing cola-colored urine aligns with the expected symptom in glomerulonephritis. The other options are less indicative of glomerulonephritis: choice A indicates normal kidney function, choice C mentions absence of protein in the urine (which is not expected in glomerulonephritis), and choice D talks about low blood pressure (hypertension is more common in glomerulonephritis).

5. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?

• A. Hemoglobin of 11 g/dl
• B. Platelet count of 150,000
• C. INR of 2.5
• D. Potassium of 2.7 mEq/L

Correct answer: D

Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.
