A client was seen in the emergency room with a complaint of severe episodes of vomiting and diarrhea, and complains of feeling lightheaded.
Which laboratory test should the nurse prioritize?

Blood glucose levels.

Serum potassium levels.

Lipid profile.

Thyroid function tests.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Blood glucose levels are important but are not the immediate priority for assessing the cause of severe vomiting and diarrhea with lightheadedness. Electrolyte imbalances are more likely to be the cause.

Choice B rationale

Serum potassium levels should be prioritized as vomiting and diarrhea can lead to significant potassium loss, which can result in dangerous cardiac and neuromuscular symptoms. Assessing potassium levels is crucial in this scenario.

Choice C rationale

Lipid profile is not relevant in the acute assessment of severe vomiting, diarrhea, and lightheadedness. This test is more useful for long-term cardiovascular risk assessment.

Choice D rationale

Thyroid function tests are not immediately relevant to the acute symptoms of vomiting and diarrhea with lightheadedness. Electrolyte imbalances are a more immediate concern.

Correct Answer is A

Explanation

Choice A rationale

Monitoring blood glucose levels more frequently is critical when a client with type 1 diabetes is taking prednisone, as corticosteroids can raise blood glucose levels and potentially cause hyperglycemia.

Choice B rationale

Increasing sodium intake is not recommended for clients with type 1 diabetes and is unrelated to the management of prednisone-induced hyperglycemia.

Choice C rationale

Stopping all other diabetes medications is inappropriate and can lead to uncontrolled blood glucose levels. Adjustments may be needed, but discontinuation is not advised without medical supervision.

Choice D rationale

Skipping meals to prevent hyperglycemia is not a safe practice for clients with type 1 diabetes. Maintaining a balanced diet and monitoring blood glucose levels is essential.

Correct Answer is ["0.8"]

Explanation

Step 1 is to divide the dose required by the concentration available. 3,800 units ÷ 5,000 units/mL = 0.76 mL.

The final answer is 0.8 mL.
