Nursing Elites

1. Diabetes insipidus is the result of:

• A. A diet high in sugar and carbohydrates.
• B. A complicated pregnancy.
• C. A disorder of the pancreas.
• D. A disorder of the pituitary gland.

Correct answer: D

Rationale: Diabetes insipidus is caused by a disorder of the pituitary gland affecting ADH regulation. This disorder results in the decreased production or release of antidiuretic hormone (ADH), leading to the inability of the kidneys to concentrate urine properly. Choices A, B, and C are incorrect as they do not relate to the underlying cause of diabetes insipidus.

2. Which insulin has the most rapid onset of action?

• A. Lente
• B. Lispro
• C. Ultralente
• D. Humulin N

Correct answer: B

Rationale: Lispro insulin has the most rapid onset of action among the options provided. It is a rapid-acting insulin analog that is designed to control postprandial hyperglycemia effectively. Lente insulin (Choice A) and Ultralente insulin (Choice C) are intermediate-acting insulins, which have a slower onset of action compared to Lispro. Humulin N (Choice D) is a neutral protamine Hagedorn (NPH) insulin, which is an intermediate-acting insulin, not rapid-acting like Lispro. Therefore, the correct choice is Lispro.

3. A charge nurse notices that two staff nurses are not taking meal breaks during their shifts. Which of the following actions should the nurse take first?

• A. Discuss time management strategies with the nurses
• B. Provide coverage for the nurses' breaks
• C. Determine the reasons the nurses are not taking scheduled breaks
• D. Review policies for taking scheduled breaks

Correct answer: C

Rationale: The correct answer is to determine the reasons the nurses are not taking scheduled breaks. This action is crucial as it allows the charge nurse to understand the underlying causes for the behavior. By identifying the reasons, the nurse can then address the root of the issue effectively. Option A is incorrect because discussing time management strategies may not address the specific reasons for not taking breaks. Option B is incorrect as providing coverage for breaks does not address the underlying cause of the issue. Option D is also incorrect as reviewing policies should come after understanding the reasons for the behavior.

4. A nurse in the emergency department is preparing to care for a client who arrived via ambulance. The client is disoriented and has a cardiac arrhythmia. Which of the following actions should the nurse take?

• A. Proceed with treatment without obtaining written consent
• B. Contact the client's next of kin to obtain consent for treatment
• C. Have the client sign a consent for treatment
• D. Notify risk management before initiating treatment

Correct answer: A

Rationale: In emergency situations where a client is disoriented and has a cardiac arrhythmia, obtaining written consent may not be possible due to the urgency of the situation. The priority is to provide immediate treatment to ensure patient safety. Contacting the next of kin or having the client sign a consent form would cause unnecessary delays in providing critical care. Notifying risk management before initiating treatment is not the most appropriate action when dealing with a time-sensitive situation like a cardiac arrhythmia.

5. Insulin forces which of the following electrolytes out of the plasma and into the cells?

• A. Calcium
• B. Magnesium
• C. Phosphorus
• D. Potassium

Correct answer: D

Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.
