A nurse is reviewing the laboratory results for a client who reports vomiting and diarrhea for 2 days.Which of the following laboratory findings should the nurse expect?

Hypermagnesemia.

Hyperkalemia.

Hyponatremia.

Hypocalcemia.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Hypermagnesemia is less common with vomiting and diarrhea. These conditions usually cause a loss of magnesium rather than an excess.

Choice B rationale

Hyperkalemia is also less typical. Vomiting and diarrhea tend to cause potassium loss, leading to hypokalemia instead.

Choice C rationale

Hyponatremia is common as vomiting and diarrhea result in the loss of sodium and water, leading to low blood sodium levels.

Choice D rationale

Hypocalcemia is not a primary result of vomiting and diarrhea. Calcium levels are usually not directly affected by gastrointestinal fluid loss.

Correct Answer is C

Explanation

Choice A rationale

Assessing pain levels is a nursing task requiring clinical judgment, which is beyond the scope of an assistive personnel's duties.

Choice B rationale

Checking an IV site for redness or swelling also requires clinical assessment skills, which are tasks for the nurse.

Choice C rationale

Measuring intake and output is a routine task that can be safely delegated to an assistive personnel. It involves straightforward measurement and recording.

Choice D rationale

Reinforcing teaching about crutch-gait walking requires specific patient education, which falls under the nurse's responsibilities.

A. "I'm glad to have the opportunity to choose what kind of care I receive while I still can.”. B. "I can't change my mind about the care I will receive once I sign my living will.”. C. "Once I fill out my living will, there will be a 1-month delay before it is legally binding.”. D. "If I want life support, I'll need to sign a separate consent form first.”.

Correct Answer is A

Explanation

Choice A rationale

This statement indicates that the client understands advance directives allow them to make decisions about their care while they are still capable. This reflects the purpose of advance directives, which is to respect and uphold the client’s autonomy and choices regarding their medical care.

Choice B rationale

This statement is incorrect because clients can change their advance directives or living will at any time. The purpose of these documents is to provide flexibility and ensure that the client's current wishes are followed.

Choice C rationale

This statement is incorrect. Once a living will is signed and witnessed or notarized, it becomes legally binding without a waiting period. The delay mentioned here is not a part of the advance directive process.

Choice D rationale

This statement is not accurate. A living will usually includes decisions about life support, and a separate consent form is not typically needed for those decisions. The client’s wishes regarding life support would be documented in the living will itself.
