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. The healthcare provider assesses a patient suspected of having an asthma attack. Which of the following is a common clinical manifestation of this condition?

• A. Audible crackles and orthopnea
• B. An audible wheeze and use of accessory muscles
• C. Audible crackles and use of accessory muscles
• D. Audible wheeze and orthopnea

Correct answer: B

Rationale: Choice B, 'An audible wheeze and use of accessory muscles,' is the correct answer. In asthma, patients commonly present with wheezing due to airway constriction and the use of accessory muscles to aid in breathing. Audible crackles (rales) are more commonly associated with conditions like pneumonia, congestive heart failure, or pulmonary fibrosis. Orthopnea, which is difficulty breathing while lying flat, is typically seen in conditions like heart failure or chronic obstructive pulmonary disease, rather than asthma. Choice C is incorrect as crackles are not a typical finding in asthma. Choice D is incorrect as orthopnea is not a common clinical manifestation of asthma.

3. A patient is being admitted to the ICU with a severe case of encephalitis. Which of these drugs would the nurse not expect to be prescribed for this condition?

• A. Acyclovir (Zovirax)
• B. Mannitol (Osmitrol)
• C. Lactated Ringer's
• D. Phenytoin (Dilantin)

Correct answer: C

Rationale: In the treatment of encephalitis, medications like Acyclovir and Phenytoin are commonly prescribed. Acyclovir is an antiviral medication used to treat viral infections like herpes simplex virus, which can cause encephalitis. Phenytoin is an antiepileptic drug that may be used to manage seizures associated with encephalitis. Mannitol is a diuretic used to reduce intracranial pressure (ICP) by decreasing cerebral edema. Lactated Ringer's solution, on the other hand, is primarily used in fluid replacement therapy and may not be indicated if a patient is at risk for high ICP, as excessive fluid administration could worsen cerebral edema and increase ICP.

4. Application - The nurse is caring for a patient who has the following labs: Creatinine 2.5mg/dL, WBC 11,000 cells/mL, and Hemoglobin of 12 g/dL. Based on this information, which of these orders would the nurse question?

• A. Administer 30 Units of Lantus Daily
• B. CT of the spine with contrast
• C. X-ray of the abdomen and chest
• D. Administer heparin subcutaneously 5,000 Units every 12 hours

Correct answer: B

Rationale: The correct answer is to question the order for a CT of the spine with contrast. The patient's elevated creatinine level of 2.5mg/dL indicates impaired kidney function. Contrast agents are nephrotoxic and can further compromise kidney function in patients with existing nephropathy. Therefore, it is crucial to avoid contrast-enhanced imaging studies in patients with impaired renal function. Choice A: Administering 30 Units of Lantus Daily is not contraindicated based on the provided lab values. Choice C: Ordering an X-ray of the abdomen and chest is not contraindicated based on the provided lab values. Choice D: Administering heparin subcutaneously at 5,000 Units every 12 hours is not contraindicated based on the provided lab values.

5. Which client is at highest risk for developing a pressure ulcer?

• A. 23 year-old in traction for fractured femur
• B. 72 year-old with peripheral vascular disease, who is unable to walk without assistance
• C. 75 year-old with left sided paresthesia and is incontinent of urine and stool
• D. 30 year-old who is comatose following a ruptured aneurysm

Correct answer: C

Rationale: Risk factors for pressure ulcers include: immobility, absence of sensation, decreased LOC, poor nutrition and hydration, skin moisture, incontinence, increased age, decreased immune response. This client has the greatest number of risk factors.
