Nursing Elites

1. A patient with hyperthyroidism is prescribed propylthiouracil (PTU). What is the primary purpose of this medication?

• A. Increase thyroid hormone production
• B. Suppress thyroid hormone production
• C. Enhance iodine absorption
• D. Stimulate the thyroid gland

Correct answer: B

Rationale: Propylthiouracil (PTU) is a medication used to treat hyperthyroidism by suppressing the production of thyroid hormones. It works by inhibiting the enzyme responsible for the synthesis of thyroid hormones, thereby reducing their levels in the body. This helps to alleviate the symptoms of hyperthyroidism and restore thyroid hormone levels to normal range.

2. A client with heart failure is prescribed digoxin (Lanoxin). Which instruction should the nurse include in the client's teaching plan?

• A. Take your pulse before each dose and hold the medication if your pulse is below 60 beats per minute.
• B. Increase your intake of foods high in potassium.
• C. Take the medication with a high-fiber meal to enhance absorption.
• D. Skip a dose if you feel dizzy or lightheaded.

Correct answer: A

Rationale: The correct instruction for a client prescribed digoxin is to take their pulse before each dose and hold the medication if the pulse is below 60 beats per minute. This is crucial to prevent digoxin toxicity, as digoxin can cause adverse effects when the pulse rate is too low. Monitoring the pulse regularly ensures safety and appropriate management of the medication.

3. A male infant born at 30-weeks gestation at an outlying hospital is being prepared for transport to a Level IV neonatal facility. His respirations are 90/min, and his heart rate is 150 beats per minute. Which drug is the transport team most likely to administer to this infant?

• A. Ampicillin (Omnipen) 25 mg/kg slow IV push.
• B. Gentamicin sulfate (Garamycin) 2.5 mg/kg IV.
• C. Digoxin (Lanoxin) 20 micrograms/kg IV.
• D. Beractant (Survanta) 100 mg/kg per endotracheal tube.

Correct answer: D

Rationale: In this scenario, the infant is a preterm neonate with respiratory distress and is being transported to a Level IV neonatal facility. The drug most likely to be administered by the transport team is Beractant (Survanta) via endotracheal tube. Beractant is a surfactant used to treat respiratory distress syndrome in preterm infants by improving lung compliance and reducing the need for mechanical ventilation.

4. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

5. A client with a history of chronic alcohol use is admitted with confusion and an unsteady gait. Which deficiency should the nurse suspect?

• A. Thiamine (Vitamin B1)
• B. Cyanocobalamin (Vitamin B12)
• C. Folic acid
• D. Vitamin D

Correct answer: A

Rationale: The correct answer is Thiamine (Vitamin B1). Chronic alcohol use can lead to thiamine deficiency, which can result in neurological symptoms such as confusion and an unsteady gait. Thiamine is essential for proper brain function and nerve conduction, and its deficiency is common in individuals with alcohol use disorder. Cyanocobalamin (Vitamin B12) deficiency can also present with neurological symptoms, but in this case, the patient's history of chronic alcohol use points more towards thiamine deficiency. Folic acid deficiency typically presents with symptoms like fatigue and megaloblastic anemia. Vitamin D deficiency is associated with bone health issues rather than neurological symptoms.
