A 4-year-old patient is brought to the clinic because the child has not recovered from a respiratory infection. The patient is pale and lethargic. Leukemia is suspected. Which lab value, if elevated, would support the diagnosis of leukemia?
Red blood cell count.
White blood cell count.
Platelet count.
Hematocrit.
The Correct Answer is B
Choice A rationale:
The red blood cell count is not typically elevated in leukemia. Leukemia primarily affects the white blood cells and their precursors in the bone marrow.
Choice B rationale:
Leukemia involves uncontrolled proliferation of white blood cells. An elevated white blood cell count, especially with abnormal cell types, can support the diagnosis of leukemia.
Choice C rationale:
Platelet count abnormalities are common in leukemia, but an elevated platelet count is more often associated with other conditions such as essential thrombocytosis, not necessarily leukemia.
Choice D rationale:
Hematocrit measures the volume of red blood cells in the blood and is not directly indicative of leukemia. Leukemia primarily affects white blood cells and does not significantly impact hematocrit levels.

Correct Answer is A
Explanation
Choice A rationale:
Monitoring the stool consistency is a crucial nursing action to assess the effectiveness of pancreatic enzyme replacement therapy. Patients with pancreatic insufficiency, such as those with cystic fibrosis, may have difficulty digesting fats properly. Improved stool consistency, specifically a reduction in greasy and foul-smelling stools, indicates that the pancreatic enzymes are aiding in fat digestion.
Choice B rationale:
Pupillary reflex response assessment is unrelated to pancreatic enzyme replacement therapy. It is more commonly performed to assess neurological status or the effects of medications affecting the autonomic nervous system.
Choice C rationale:
Listening to breath sounds is important for assessing respiratory status, but it does not directly reflect the effectiveness of pancreatic enzyme replacement therapy.
Choice D rationale:
Auscultating the apical pulse rate is a general assessment of cardiovascular function and does not provide information about the effectiveness of pancreatic enzyme replacement therapy.
Correct Answer is B
Explanation
Choice A rationale:
Polyarthritis is a manifestation of rheumatic fever, but it is not the primary manifestation. The main manifestation is carditis, involving inflammation of the heart's valves and structures.
Choice B rationale:
Carditis is a hallmark manifestation of rheumatic fever. It involves inflammation of the heart's valves and structures, leading to murmurs and potential long-term cardiac damage.
Choice C rationale:
Janeway lesions are not associated with rheumatic fever. They are painless, small erythematous or hemorrhagic macules on the palms and soles, typically seen in infective endocarditis.
Choice D rationale:
Subcutaneous nodules are not a primary manifestation of rheumatic fever. These nodules, which are firm and nontender, may develop over bony prominences in cases of severe rheumatic fever.
Choice E rationale:
Cervical lymphadenopathy is not a characteristic manifestation of rheumatic fever. This type of lymphadenopathy is more commonly seen in infections or lymphatic malignancies.
