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 B
Explanation
Choice A rationale:
Inflammation and edema of the scrotum is not a typical symptom of gonorrhea. Scrotal involvement is more commonly associated with conditions like epididymitis.
Choice B rationale:
Painful urination with yellow urethral discharge is a classic symptom of gonorrhea. The infection affects the genitourinary tract, causing discomfort during urination and a characteristic purulent discharge.
Choice C rationale:
Maculopapular rash in the genital area is not a typical presentation of gonorrhea. This type of rash might be seen in other infections, such as syphilis.
Choice D rationale:
Red, hard lesion on the penis is not a common manifestation of gonorrhea. This description more closely matches the appearance of a primary syphilis chancre.
Correct Answer is A
Explanation
Choice A rationale:
The statement "I feel numb. I just can't believe this is happening”. reflects the emotional reaction of shock. Shock is a common initial response to distressing news, as the individual may find it difficult to process and accept the reality of the situation.
Choice B rationale:
Denial is the refusal to accept reality and is often accompanied by a lack of awareness or acknowledgment of the situation. The mother's statement does not demonstrate denial, as she acknowledges the situation but expresses disbelief.
Choice C rationale:
Anger is a stage of grief characterized by feelings of hostility and resentment. The mother's statement does not show anger, as she does not express any aggressive or hostile emotions.
Choice D rationale:
Depression involves feelings of extreme sadness, hopelessness, and low mood. The mother's statement does not directly convey depression; rather, it indicates a sense of disbelief and numbness.
