Nursing Elites

1. A healthcare professional is reviewing a client's laboratory report and notes that the serum calcium level is 4.0 mg/dL. The healthcare professional understands that which condition most likely caused this serum calcium level?

• A. Prolonged bed rest
• B. Renal insufficiency
• C. Hyperparathyroidism
• D. Excessive ingestion of vitamin D

Correct answer: A

Rationale: Prolonged bed rest can lead to hypocalcemia due to decreased mobility and bone resorption. In this scenario, the low serum calcium level of 4.0 mg/dL is likely a result of decreased bone activity and calcium release due to prolonged bed rest. Renal insufficiency would more likely lead to hypercalcemia due to impaired excretion of calcium by the kidneys. Hyperparathyroidism is characterized by increased calcium levels as a result of excess parathyroid hormone. Excessive ingestion of vitamin D can cause hypercalcemia by increasing intestinal absorption of calcium.

2. A charge nurse is making staff assignments on a medical-surgical unit. Which of the following tasks should the nurse plan to delegate to an assistive personnel?

• A. Measuring oxygen saturation for a client who has dyspnea
• B. Inserting a rectal suppository for a client who is vomiting
• C. Performing nasal hygiene for a client who has an NG tube
• D. Pouching a client's ostomy bag for a new colostomy

Correct answer: D

Rationale: Pouching a new colostomy is a task that can be safely and appropriately delegated to an assistive personnel as it falls within their scope of practice. Measuring oxygen saturation (Choice A) requires a higher level of training and assessment, making it unsuitable for delegation. Inserting a rectal suppository (Choice B) and performing nasal hygiene (Choice C) involve invasive procedures that are typically performed by licensed nursing staff due to the associated risks and complexities, making them inappropriate for delegation to assistive personnel.

3. Which atrioventricular heart block is also referred to as Mobitz II?

• A. Third-degree atrioventricular heart block
• B. Second-degree atrioventricular heart block
• C. First-degree atrioventricular heart block
• D. Complete heart block

Correct answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.

4. A nurse is caring for a client who wanders through the halls yelling obscenities at staff, other clients, and visitors. Which of the following actions should the nurse take?

• A. Keep the client in their room with the door closed
• B. Contact a family member to come and sit with the client
• C. Place the client in a wheelchair with a lap tray
• D. Administer a sedative to the client

Correct answer: B

Rationale: When dealing with a client exhibiting disruptive behavior like yelling obscenities, involving a family member can provide emotional support and help in de-escalating the situation. Keeping the client isolated in their room (Choice A) may lead to further agitation. Placing the client in a wheelchair (Choice C) or administering a sedative (Choice D) should not be the first interventions for managing behavioral issues.

5. What percentage of term newborns have a congenital heart disease due to environmental risk factors such as maternal alcoholism or drug ingestion?

• A. 2% to 4%
• B. 10% to 20%
• C. 5% to 10%
• D. 7% to 9%

Correct answer: A

Rationale: The correct answer is A: 2% to 4%. According to research, 2% to 4% of term newborns have congenital heart disease due to environmental risk factors such as maternal alcoholism or drug ingestion. Choices B, C, and D provide percentages that are higher than the actual prevalence of congenital heart disease in newborns caused by environmental factors, making them incorrect.
