A nurse is preparing to administer diphenhydramine 25 mg PO every 6 hr. to an older adult client who has rhinitis. The amount available is diphenhydramine syrup 12.5 mg/5 mile How many ml should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A Reason:
Checking the client for ecchymosis is appropriate. Thrombocytopenia increases the risk of bleeding and bruising, so monitoring for ecchymosis (bruising) is essential to detect any signs of bleeding. Ecchymosis can occur more easily in individuals with low platelet counts.
Choice B Reason:
Initiating protective isolation for the client is typically unnecessary solely due to thrombocytopenia. Protective isolation is generally for clients with conditions that compromise their immune system or make them more susceptible to infections.
Choice C Reason:
Administering ibuprofen for a mild headache might not be advisable in someone with thrombocytopenia because ibuprofen can affect platelet function and potentially increase the risk of bleeding.
Choice D Reason:
Instructing the client to shave with a disposable razor isn't recommended because using a sharp blade can increase the risk of cuts and bleeding in someone with a low platelet count. Using an electric razor or avoiding shaving might be safer options to prevent injury and bleeding.

Choice A Reason:
Absence of Chvostek's sign is a wrong indication. Chvostek's sign is a twitching of facial muscles in response to tapping the facial nerve and is typically associated with low blood calcium levels (hypocalcemia). It's not directly related to hyperglycemia or high blood sugar levels. Hyperglycemia refers to high blood sugar levels, commonly associated with diabetes mellitus.
Choice B Reason:
Presence of Kussmaul respirations is a right indication. Kussmaul respirations are deep, rapid, and labored breathing patterns often seen in individuals with diabetic ketoacidosis (DKA), a severe complication of diabetes characterized by significantly high blood sugar levels and the presence of ketones in the blood and urine. This type of breathing pattern is the body's attempt to compensate for the acidic state caused by high blood sugar and the buildup of ketones.
Choice C Reason:
Presence of diaphoresis is a wrong indication. Diaphoresis refers to excessive sweating, which can occur due to various reasons such as physical activity, heat, stress, or certain medical conditions. While hyperglycemia can cause symptoms like increased thirst and frequent urination, diaphoresis alone is not a specific indicator of high blood sugar levels.
Choice D Reason:
Absence of urinary ketones is a wrong indication. The presence of urinary ketones indicates the body is breaking down fat for energy, which commonly occurs during periods of insufficient insulin (such as in hyperglycemia or diabetic ketoacidosis). However, the absence of urinary ketones doesn't necessarily rule out hyperglycemia. It's possible for hyperglycemia to be present without ketones in the urine, especially in the early stages or when the body is still managing blood sugar levels without significant ketone production.
