An adult male is experiencing increased fatigue and occasional palpitations at rest. Which laboratory data would the nurse identify as consistent with these symptoms?
Red Blood Cells 48,000/μL (normal 4,700,000-6,100,000/μL)
Platelets (Plts) of 120,000/μL (normal 150,000-400,000/μL)
Hemoglobin (Hgb) of 6.9g/dL (normal 14-18g/dL)
White blood cell count (WBC) 11,000/mm³ (normal 5,000-10,000/mm³)
The Correct Answer is C
Choice A reason: The red blood cell (RBC) count provided is significantly below the normal range (4,700,000-6,100,000/μL). However, the unit of measure given in the question (48,000/μL) is incorrect for RBCs, so it may not be consistent with the symptoms of fatigue and palpitations. Typically, a low RBC count can contribute to these symptoms, but in this case, the measurement provided is not clear.
Choice B reason: Platelets of 120,000/μL are below the normal range (150,000-400,000/μL). While low platelet counts (thrombocytopenia) can lead to bleeding and bruising, they are not typically associated with symptoms of fatigue and palpitations. This finding is more indicative of a potential bleeding disorder rather than anemia or another condition that would cause the given symptoms.
Choice C reason: Hemoglobin (Hgb) of 6.9g/dL is significantly below the normal range (14-18g/dL) and indicates severe anemia. Anemia is a common cause of fatigue and palpitations because the body has a reduced capacity to carry oxygen to tissues. Low hemoglobin levels can lead to decreased oxygen delivery, resulting in increased fatigue and compensatory palpitations as the heart works harder to circulate oxygen-poor blood.
Choice D reason: White blood cell (WBC) count of 11,000/mm³ is slightly above the normal range (5,000-10,000/mm³) and indicates a mild leukocytosis, which is usually a sign of infection or inflammation. While leukocytosis can cause fatigue if there is an underlying infection, it is not directly associated with palpitations and severe fatigue. The primary concern with fatigue and palpitations lies more with oxygen-carrying capacity, which is affected by hemoglobin levels.

Correct Answer is B
Explanation
Choice A reason: Aggressive physical therapy is not a treatment for Addison's disease. While physical therapy can be beneficial for certain conditions, it does not address the hormonal deficiencies that are characteristic of Addison's disease.
Choice B reason: Lifelong hormone therapy with glucocorticoids and mineralocorticoids is the standard treatment for Addison's disease. This involves taking medications to replace the hormones that the adrenal glands are not producing enough of, specifically glucocorticoids (such as hydrocortisone, prednisone, or dexamethasone) and mineralocorticoids (such as fludrocortisone). These medications help to maintain normal hormone levels in the body, manage symptoms, and prevent adrenal crises.
Choice C reason: Diuretics are not typically used as a primary treatment for Addison's disease. They are used to manage fluid balance and blood pressure in other conditions, but they do not replace the deficient hormones in Addison's disease.
Choice D reason: Lifelong insulin treatment is used for managing diabetes mellitus, not Addison's disease. Addison's disease involves adrenal hormone deficiencies, which are treated with hormone replacement therapy, not insulin.
Correct Answer is ["C","D","E","G"]
Explanation
Choice A reason: Insert indwelling urinary catheter. This task requires clinical judgment, sterile technique, and expertise. It is an invasive procedure that should be performed by a registered nurse or a physician.
Choice B reason: Monitor IV D5 1/2 NS with 20 mEq KCl at 75 m/hr. Monitoring IV fluids and medications involves assessing the patient’s response to treatment, recognizing potential complications, and making clinical decisions. This task requires the expertise of a registered nurse.
Choice C reason: Empty urinary catheter and measure the output. This task can be delegated to a nursing aide as it involves routine measurement and documentation, which does not require clinical judgment. It is a simple procedure that can be safely performed by a trained aide.
Choice D reason: Collect a stool sample for occult blood testing. This is a straightforward task that can be delegated to a nursing aide. It involves collecting and labeling the sample correctly, which does not require advanced clinical skills or judgment.
Choice E reason: Daily weights. This task can be safely delegated to a nursing aide. It involves measuring and recording the patient’s weight, which is a routine procedure and does not require clinical judgment.
Choice F reason: Notify the MD of any signs of bleeding. This task involves assessing the patient for signs of bleeding, which requires clinical judgment and should be performed by a registered nurse. The nurse must determine the significance of the findings and communicate them appropriately to the physician.
Choice G reason: Vital signs every 4 hours. Monitoring vital signs is a routine task that can be delegated to a nursing aide. It involves measuring and recording the patient’s blood pressure, heart rate, respiratory rate, and temperature, which does not require advanced clinical skills.
