Nursing Elites

1. A healthcare provider is reviewing the laboratory report of a client with a prescription for digoxin. Which result requires withholding the medication?

• A. Digoxin 0.8 ng/mL
• B. Sodium 145 mEq/L
• C. BUN 20 mg/dL
• D. Potassium 3.1 mEq/L

Correct answer: D

Rationale: The correct answer is D. A low potassium level (3.1 mEq/L) can increase the risk of digoxin toxicity. Hypokalemia can potentiate the effects of digoxin on the heart, leading to serious dysrhythmias. Choices A, B, and C are within normal ranges and do not indicate a need to withhold digoxin.

2. Which electrolyte imbalance should be closely monitored in patients on furosemide?

• A. Hypokalemia
• B. Hyponatremia
• C. Hyperkalemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss in the body, resulting in hypokalemia. Monitoring potassium levels is crucial in patients on furosemide to prevent complications such as cardiac arrhythmias and muscle weakness. Choice B, hyponatremia, is not typically associated with furosemide use. Hyperkalemia (choice C) and hypercalcemia (choice D) are not commonly linked to furosemide therapy; therefore, they are incorrect choices.

3. What is the best intervention for a patient with a suspected pulmonary embolism?

• A. Administer oxygen
• B. Administer anticoagulants
• C. Reposition the patient
• D. Administer bronchodilators

Correct answer: A

Rationale: Administering oxygen is the best intervention for a patient with a suspected pulmonary embolism because it helps alleviate respiratory distress and improve oxygenation. Oxygen therapy is crucial to ensure adequate oxygen levels in the blood due to the obstruction in the pulmonary circulation caused by the embolism. Administering anticoagulants (choice B) is a treatment for confirmed pulmonary embolism rather than a suspected case. Repositioning the patient (choice C) or administering bronchodilators (choice D) would not directly address the underlying issue of impaired gas exchange and oxygen delivery associated with pulmonary embolism.

4. When providing teaching for a child prescribed ferrous sulfate, which of the following instructions should the nurse include?

• A. Take with meals
• B. Take at bedtime
• C. Take with a glass of milk
• D. Take with a glass of orange juice

Correct answer: D

Rationale: The correct answer is D, 'Take with a glass of orange juice.' Ferrous sulfate is best absorbed with vitamin C, making orange juice the preferred choice. Choices A, B, and C are incorrect because taking ferrous sulfate with meals, at bedtime, or with milk can reduce its absorption due to interactions with food components like calcium, inhibiting the iron absorption process.

5. A healthcare professional is reviewing the medical record of a client who has a new prescription for ceftriaxone. The healthcare professional should identify which of the following findings as a contraindication to this medication?

• A. Seizure disorder
• B. Hypertension
• C. Penicillin allergy
• D. Hyperlipidemia

Correct answer: C

Rationale: The correct answer is C: Penicillin allergy. Penicillin allergy is a contraindication for ceftriaxone because both medications are beta-lactam antibiotics. Seizure disorder (choice A), hypertension (choice B), and hyperlipidemia (choice D) are not contraindications for ceftriaxone and do not directly affect the use of this antibiotic.
