A nurse is reviewing the laboratory results for four clients. Which of the following results is the priority for the nurse to report to the provider?

WBC 11,000/mm² in a client who is starting treatment for a methicillin-resistant staphylococcus aureus (MRSA) infection.

Serum pH 7.25 in a client who has type 1 diabetes mellitus.

Hematocrit 26% in a client who has sickle cell disease.

Urine specific gravity 1.032 in a client who is diagnosed with dehydration.

Answer and Explanation

The Correct Answer is B

Choice A rationale:
An elevated WBC count (11,000/mm²) in a client starting treatment for MRSA infection may indicate an inflammatory response, but it is expected in this scenario, and the priority is not as high as other critical lab values.
Choice B rationale:
A serum pH of 7.25 indicates acidosis, which is a potentially life-threatening condition. In type 1 diabetes mellitus, diabetic ketoacidosis (DKA) is a common complication that can lead to metabolic acidosis. This lab result is a priority as it requires immediate attention.
Choice C rationale:
Hematocrit of 26% in a client with sickle cell disease might be low, but it is not the priority over the critically abnormal lab value of serum pH in option B.
Choice D rationale:
A urine specific gravity of 1.032 in a client diagnosed with dehydration is elevated, indicating concentrated urine due to dehydration. While dehydration is concerning, it is not as high-priority as the potentially life-threatening acidosis in option B.

Correct Answer is D

Explanation

Choice A rationale:
Allergy to eggs is not a contraindication for taking chondroitin with glucosamine. These supplements do not contain eggs and are generally safe for individuals with egg allergies.
Choice B rationale:
Hypotension is not directly related to the use of chondroitin with glucosamine. These supplements are not known to cause significant changes in blood pressure.
Choice C rationale:
History of hypoglycemia is not a specific concern with chondroitin and glucosamine supplements. These supplements do not significantly impact blood sugar levels in people without diabetes.
Choice D rationale:
The correct choice. The nurse should instruct the client to use chondroitin with glucosamine with caution if they are on anticoagulant therapy. Chondroitin and glucosamine may have mild anticoagulant effects, and when combined with prescribed anticoagulant medications, there is a potential risk of increased bleeding or altered blood clotting times. It is essential to monitor the client's coagulation parameters closely if they decide to use these supplements.

A. 0.4 mL. B. 0.5 mL. C. 0.8 mL. D. 1.0 mL.

Correct Answer is B

Explanation

Let's break down the calculation:

Given:

Patient weight: 154 lbs
Enoxaparin dosage: 0.75 mg/kg
Available enoxaparin: 60 mg/0.6 mL

Step 1: Convert pounds to kilograms:

1 lb is approximately 0.4536 kg
So, 154 lbs = 154 * 0.4536 kg/lb = 69.85 kg (approximately 70 kg)

Step 2: Calculate the total dose of enoxaparin:

Desired dose = 0.75 mg/kg * 70 kg = 52.5 mg

Step 3: Determine the volume to administer:

We have enoxaparin 60 mg/0.6 mL
To find the volume for 52.5 mg:
- (52.5 mg / 60 mg) * 0.6 mL = 0.525 mL
- Rounded to the nearest tenth, this is 0.5mL.

Therefore, the nurse should administer 0.5mL of enoxaparin
