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 D
Explanation
Choice A reason: Checking the blood pressure and pulse is important as part of the routine monitoring of vital signs to assess the patient's hemodynamic status. However, it is not the first action to take following a thyroidectomy. Ensuring that the patient's airway is clear and that there is no respiratory distress is paramount, as any compromise in the airway can lead to life-threatening situations. Blood pressure and pulse can be checked after confirming the patient is breathing properly.
Choice B reason: Observing the dressing for bleeding is also important because post-operative bleeding can be a serious concern. However, this action should follow the assessment of the patient's airway. If the patient is experiencing respiratory distress, addressing the airway takes precedence. Once it is confirmed that the airway is clear, then the nurse can check for bleeding and ensure the dressing is intact.
Choice C reason: Supporting the patient's head with pillows is beneficial for comfort and proper positioning, especially to avoid strain on the surgical site. However, positioning should not be the first priority. Ensuring that the patient's airway is clear and that there is no respiratory compromise is the most urgent concern. Proper positioning can be done after confirming that the patient is breathing adequately.
Choice D reason: Assessing the patient's respiratory effort is the first and most critical action. Following a thyroidectomy, there is a risk of respiratory complications due to potential swelling, bleeding, or damage to the trachea and surrounding structures. Immediate assessment of respiratory effort ensures that the airway is patent and the patient is not in respiratory distress. This step is crucial to prevent hypoxia and other serious complications.
Correct Answer is B
Explanation
Choice A reason: Asking the patient why the wandering episodes have occurred might not be effective because patients with Alzheimer's disease often have memory and cognitive impairments that make it difficult for them to understand or articulate the reasons for their behavior. Additionally, it may not address the immediate safety concerns associated with wandering.
Choice B reason: Placing the patient in a room close to the nurse's station is a practical and effective measure to enhance patient safety. Proximity to the nurse's station allows for closer supervision and quicker response if the patient attempts to wander. This action helps prevent potential accidents and ensures that the patient receives timely interventions if needed. It is a proactive approach to managing the wandering behavior commonly seen in patients with Alzheimer's disease.
Choice C reason: Reorienting the patient several times daily is an important aspect of care for individuals with Alzheimer's disease, as it can help reduce confusion and anxiety. However, this alone may not be sufficient to prevent wandering. While reorientation is beneficial, the immediate safety of the patient requires additional measures, such as close supervision.
Choice D reason: Having the family bring in familiar items can provide comfort and a sense of security for the patient, which is important in managing Alzheimer's disease. Familiar objects may help reduce anxiety and agitation, but they do not directly address the safety concerns associated with wandering. This action should be part of a comprehensive care plan that includes measures to prevent wandering and ensure patient safety.
