A nurse is reviewing the medical record for a newly admitted client. Which of the following laboratory values should the nurse report to the provider?

Sodium 140 mEq/L

Potassium 5.8 mEq/L

Calcium 9.6 mg/dL

Magnesium 1.9 mEq/L

Answer and Explanation

The Correct Answer is B

Choice A reason:

Sodium 140 mEq/L is incorrect because it falls within the normal range (135-145 mEq/L).

Choice B reason:

A potassium level of 5.8 mEq/L is appropriate because it is above the normal range (typically around 3.5-5.0 mEq/L). Elevated potassium levels, known as hyperkalaemia, can lead to serious cardiac disturbances, including arrhythmias or even cardiac arrest. It is important to notify the healthcare provider promptly so that appropriate interventions can be initiated to address the high potassium level.

Choice C reason:

Calcium 9.6 mg/dL is incorrect because it is within the normal range (8.5-10.5 mg/dL).

Choice D reason:

Magnesium 1.9 mEq/L is incorrect because it is within the normal range (1.5-2.5 mEq/L).

Correct Answer is D

Explanation

Choice A reason:
Placing the wasted portion of the controlled substance in the sharp container is not correct. Wasted controlled substances should be disposed of according to specific regulations and facility protocols.
Choice B reason:
Asking a second nurse to record her signature when wasting an unused portion of the controlled substance is not a standard practice. The process for wasting controlled substances usually involves following specific documentation procedures, but this does not necessarily require a second nurse's signature.
Choice C reason:
Over-verifying the count total of the controlled substance after removing the amount needed is not a standard practice. It's important to maintain accurate records and documentation, but additional verification of the count total may not be necessary in this context.
Choice D reason:
Reporting any discrepancy in the count total of the controlled substance after administration is the appropriate action. When administering a controlled substance, it is important to accurately account for the medication before and after administration. Any discrepancy in the count of the controlled substance should be reported and documented according to facility policy. This helps ensure proper tracking and accountability of controlled substances, which is crucial for maintaining patient safety and preventing potential diversion or misuse.

A. "Delirium has an abrupt onset." B. "Delirium does not affect a client's sleep cycle." C. "Delirium has a slow progression." D. "Delirium does not affect a client's perception of her environment."

Correct Answer is A

Explanation

Choice A reason:
Delirium is a sudden and acute change in mental status characterized by confusion, disorientation, altered consciousness, and other cognitive disturbances. It has an abrupt onset and is often related to an underlying medical condition, medication, or other factors such as infections or metabolic imbalances.
Choice B reason:
Delirium can indeed affect a client's sleep cycle. It often disrupts sleep patterns and can lead to sleep disturbances
Choice C reason:
Delirium does not have a slow progression. It is typically characterized by a rapid and fluctuating course, and it can develop over hours to days.
Choice D reason:
Delirium does affect a client's perception of their environment. Clients with delirium may experience hallucinations, paranoia, and other alterations in perception. They may be unable to accurately interpret or interact with their surroundings.
