Nursing Elites

1. A female patient is prescribed metformin for glucose control. The patient is on NPO status pending a diagnostic test. The nurse is most concerned about which side effect of metformin?

• A. Diarrhea and Vomiting
• B. Dizziness and Drowsiness
• C. Metallic taste
• D. Hypoglycemia

Correct answer: D

Rationale: The correct answer is 'Hypoglycemia.' When a patient is on NPO status (nothing by mouth) and prescribed metformin, there is an increased risk of hypoglycemia due to the absence of oral intake. Metformin, as an anti-glycemic drug, can lower blood sugar levels, and without food intake, the risk of hypoglycemia is higher. Diarrhea and vomiting are common gastrointestinal side effects of metformin but are not the main concern in this scenario. Dizziness and drowsiness are potential side effects of some medications but are not typically associated with metformin. Metallic taste is a known side effect of metformin but is not the primary concern in this situation where hypoglycemia is more critical to monitor due to the patient's NPO status.

2. A child weighing 30 kg arrives at the clinic with diffuse itching as the result of an allergic reaction to an insect bite. Diphenhydramine (Benadryl) 25 mg 3 times a day is prescribed. The correct pediatric dose is 5 mg/kg/day. Which of the following best describes the prescribed drug dose?

• A. It is the correct dose
• B. The dose is too low
• C. The dose is too high
• D. The dose should be increased or decreased, depending on the symptoms

Correct answer: B

Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day. Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.

3. A 55-year-old patient admitted with an abrupt onset of jaundice and nausea has abnormal liver function studies, but serologic testing is negative for viral causes of hepatitis. Which question by the nurse is most appropriate?

• A. Is there any history of IV drug use?
• B. Do you use any over-the-counter drugs?
• C. Are you taking corticosteroids for any reason?
• D. Have you recently traveled to a foreign country?

Correct answer: B

Rationale: The most appropriate question for the nurse to ask in this scenario is whether the patient uses any over-the-counter drugs. The patient's symptoms, negative serologic testing for viral hepatitis, and sudden onset of symptoms point towards toxic hepatitis, which can be triggered by commonly used over-the-counter medications like acetaminophen (Tylenol). Asking about IV drug use is relevant for viral hepatitis, not toxic hepatitis. Inquiring about recent travel to a foreign country is more pertinent to potential exposure to infectious agents causing viral hepatitis. Corticosteroid use is not typically associated with the symptoms described in the case.

4. What is the most common complication of chest wall injury?

• A. Hemothorax
• B. Atelectasis
• C. Pneumonia
• D. Pneumothorax

Correct answer: C

Rationale: Pneumonia is the most common complication of chest wall injury. Chest wall trauma can lead to impaired lung function, making patients more susceptible to pneumonia due to reduced ability to clear secretions and impaired breathing. While hemothorax and pneumothorax are potential complications of chest wall injury, pneumonia is more commonly encountered. Atelectasis, although a common pulmonary complication, is not typically the most common complication seen in chest wall injuries.

5. A serum potassium level of 3.2 mEq/L (3.2 mmol/L) is reported for a patient with cirrhosis who has scheduled doses of spironolactone (Aldactone) and furosemide (Lasix) due. Which action should the nurse take?

• A. Administer both drugs.
• B. Administer the spironolactone.
• C. Withhold the spironolactone and administer the furosemide.
• D. Withhold both drugs until discussed with the healthcare provider.

Correct answer: B

Rationale: A serum potassium level of 3.2 mEq/L is low (hypokalemia), which can be concerning in a patient with cirrhosis who is already at risk for electrolyte imbalances. Spironolactone is a potassium-sparing diuretic that can help increase the patient's potassium level and correct the hypokalemia. Therefore, the appropriate action for the nurse to take in this scenario is to administer the spironolactone. Withholding the spironolactone could further lower the potassium level. Furosemide, on the other hand, is a loop diuretic that can lead to potassium loss and worsen hypokalemia; hence, it should be withheld until the nurse discusses the situation with the healthcare provider. While the healthcare provider should be informed about the low potassium value, immediate administration of spironolactone is necessary to address the hypokalemia in this patient population.
