The nurse assesses a client with petechiae and ecchymosis scattered across the arms and legs. Which laboratory result should the nurse review?
White blood cell count.
Platelet count.
Red blood cell count.
Hemoglobin levels.
The Correct Answer is B
Choice A rationale
While a white blood cell count can indicate an infection or inflammation in the body, it’s not the most relevant laboratory result to review when a client presents with petechiae and ecchymosis. These symptoms are more commonly associated with platelet disorders or coagulation issues.
Choice B rationale
A platelet count is the most relevant laboratory result to review for a client with petechiae and ecchymosis. These symptoms are often caused by low platelet counts, which can lead to bleeding and bruising. Therefore, reviewing the platelet count can provide valuable information about the client’s condition.
Choice C rationale
A red blood cell count can provide information about the client’s overall health and can indicate conditions like anemia. However, it’s not directly related to the presence of petechiae and ecchymosis.
Choice D rationale
Hemoglobin levels can indicate conditions like anemia, but they’re not directly related to the presence of petechiae and ecchymosis. These symptoms are more commonly associated with platelet disorders or coagulation issues.

Correct Answer is ["42"]
Explanation
Step 1: Convert the volume from liters to milliliters. 1 liter = 1000 mL. Step 2: Convert the time from hours to minutes. 4 hours = 240 minutes.
Step 3: Calculate the rate in mL per minute. Rate = Volume ÷ Time = 1000 mL ÷ 240 min = 4.17 mL/min.
Step 4: Calculate the drops per minute. Drops per minute = Rate × Drop factor = 4.17 mL/min
× 10 gtt/mL = 41.7 gtt/min.
Step 5: Round off the result to the nearest whole number. 41.7 gtt/min rounds off to 42 gtt/min.
Correct Answer is A
Explanation
Choice A rationale
Maintaining the prescribed fluid restriction is crucial in the management of SIADH. Fluid restriction helps to prevent further dilution of sodium in the blood, which can exacerbate the symptoms of SIADH34.
Choice B rationale
Withholding the next scheduled dose of treatment is not necessarily the appropriate intervention based on the increase in serum sodium level. The treatment plan should be adjusted based on the patient’s overall clinical picture and in consultation with the healthcare provider.
Choice C rationale
Increasing neurologic checks to every 2 hours is not directly related to the increase in serum sodium level. While neurologic checks are important in monitoring the overall health status of the patient, they are not specifically indicated based on the serum sodium level alone.
Choice D rationale
Assessing for increasing fluid volume overload is not the appropriate intervention based on the increase in serum sodium level. SIADH is characterized by water retention, not fluid volume overload.
