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 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.
Correct Answer is D
Explanation
Choice A rationale
Brown, rough, greasy, wart-like papules on the face are not typically associated with overexposure to PUVA treatment. These symptoms could be indicative of a different skin condition.
Choice B rationale
Thick skin plaques topped by silvery-white scales are characteristic of psoriasis vulgaris, not overexposure to PUVA treatment. PUVA is used to treat these symptoms, not cause them.
Choice C rationale
Needing sunglasses because sunlight hurts the eyes is not a typical sign of overexposure to PUVA treatment. This could be a sign of a different issue, such as an eye condition or side effect from a different medication.
Choice D rationale
Tenderness upon palpation and generalized erythema are signs of overexposure to PUVA treatment. If a patient is overexposed to PUVA, they may experience a burning sensation, discomfort, and redness at the treatment site.
