Nursing Elites

1. A client with hyperkalemia is being treated in the emergency department. Which medication should the nurse prepare to administer?

• A. Potassium chloride
• B. Calcium gluconate
• C. Magnesium sulfate
• D. Sodium bicarbonate

Correct answer: B

Rationale: The correct answer is B, Calcium gluconate. In hyperkalemia, where potassium levels are elevated, calcium gluconate is administered to stabilize the myocardial cell membrane and protect the heart from potential arrhythmias. Potassium chloride (choice A) would worsen the condition by further increasing potassium levels. Magnesium sulfate (choice C) is not the primary treatment for hyperkalemia. Sodium bicarbonate (choice D) is used in metabolic acidosis, not specifically for hyperkalemia.

2. Which additional congenital malformation is expected in 80% of infants with a myelomeningocele?

• A. Cerebral palsy
• B. Hydrocephalus
• C. Meningitis
• D. Neuroblastoma

Correct answer: B

Rationale: Hydrocephalus is the additional congenital malformation expected in 80% of infants with a myelomeningocele. Myelomeningocele is commonly associated with hydrocephalus due to the abnormal accumulation of cerebrospinal fluid in the brain. Cerebral palsy (Choice A) is a motor disorder but not typically associated with myelomeningocele. Meningitis (Choice C) is an infection of the meninges and is not a congenital malformation. Neuroblastoma (Choice D) is a type of cancer that originates in immature nerve cells and is not a typical association with myelomeningocele.

3. Which of the following is a priority assessment for a client receiving intravenous vancomycin?

• A. Respiratory rate
• B. Blood pressure
• C. Urine output
• D. Hearing acuity

Correct answer: D

Rationale: The correct answer is D, Hearing acuity. Vancomycin is known to cause ototoxicity, which can result in hearing loss. Monitoring the client's hearing acuity is crucial to detect any early signs of ototoxicity. Assessing respiratory rate, blood pressure, and urine output are important assessments in general patient care but are not the priority when specifically monitoring for vancomycin-induced ototoxicity.

4. A client who took a camping vacation two weeks ago in a country with a tropical climate comes to the clinic describing vague symptoms and diarrhea for the past week. Which finding is most important for the nurse to report to the HCP?

• A. Weakness and fatigue
• B. Intestinal cramping
• C. Weight loss
• D. Jaundiced sclera

Correct answer: D

Rationale: The most important finding to report to the healthcare provider is a jaundiced sclera. Jaundice suggests liver involvement, which can be a sign of a serious underlying condition. Weakness and fatigue, intestinal cramping, and weight loss are important symptoms, but jaundice indicates a more urgent issue that needs immediate attention.

5. A client with peptic ulcer disease is prescribed sucralfate. What is the mechanism of action of this medication?

• A. Neutralizes stomach acid
• B. Decreases gastric acid secretion
• C. Covers the ulcer site and protects it from acid
• D. Improves gastric motility

Correct answer: C

Rationale: The correct answer is C: Covers the ulcer site and protects it from acid. Sucralfate works by forming a protective barrier over ulcers, shielding them from stomach acid and promoting healing. Choice A, neutralizing stomach acid, is incorrect as sucralfate does not neutralize acid but acts as a physical barrier. Choice B, decreasing gastric acid secretion, is not the mechanism of action of sucralfate. Choice D, improving gastric motility, is unrelated to sucralfate's action on peptic ulcers.
