A 2-year-old African American boy is brought to his pediatrician because of acute fever, apparent bone pain, and painful swelling of his hands and feet. A physical examination reveals splenomegaly and a blood test shows the presence of hemoglobin S. After the acute symptoms subside with rest, hydration, and the use of analgesics, hydroxyurea is prescribed. This drug would be expected to reduce the risk of further acute episodes of disease via which mechanism? Increasing the synthesis of hemoglobin S Increasing the oxygen-carrying capacity of hemoglobin Reducing the oxygen-carrying capacity of hemoglobin Increasing the levels of hypoxia-inducible factor Increasing the synthesis of hemoglobin F.
A child diagnosed with strep throat 3 days ago enters the clinic crying hysterically. The parent tells the practical nurse (PN) that the child screams in pain even with a light touch. The child is short of breath and anxious. Which manifestations warrant immediate intervention by the PN? A Red, hot, and swollen joints. B Pulse oximetry of 88% 02 saturation.

MK is a 58-year-old female patient (47kg) was recently admitted to a hospital due to severe COVID-related pneumonia. Her past medical history showed that she is a chronic kidney disease(CKD). Her renal function test lab result was not immediately available at the time of her admission to the hospital. She was going to be started on vancomycin 1 g IV every 12 hours for the severe pneumonia. After a loading-dose (1 g IV), two blood samples were taken from MK at 8 and 10 hours during the elimination phase (β-phase) and the plasma concentrations were found to be 14.88 and 14.21 mg/mL, respectively. Based on the concentrations given above and by referring the elimination rate constant table and/or the nomogram, calculate the following:a) Adjusted dose of vancomycin, while keeping the dosing interval constant. b) Adjusted dosing interval of vancomycin (τ), while keeping the dose constant.
A 40-year-old woman complains of fatigue and nausea of 3 months in duration. Physical examination reveals splenomegaly and | hepatomegaly. Laboratory studies show hemoglobin of 6.3 g/dL and platelets of 50,000/mL. A peripheral smear shows malignant cells with Auer rods (arrow). The patient develops diffuse purpura, and laboratory features of disseminated intravascular | coagulation (DIC). Which of the following genes is most likely found at the translocation site in this patient? O bc-1 О тус O abl • Retinoic acid receptor
83. A 25-year-old woman comes to the physician because of a 2-week history of left flank pain. She has had progressive weakness and decreased appetite during this period. Her temperature is 38°C (100.4°F). Physical examination shows left flank tenderness. Laboratory studies show a leukocyte count of 18,500/mm³. Urinalysis shows numerous RBCs and WBCs.

A) Fatty layer (Camper fascia) of the abdominal tela subcutanea B) Greater omentum C) Membranous layer (Scarpa fascia) of the abdominal tela subcutanea D) Pararenal fascia E) Perirenal (Gerota) fascia
A 48-year-old woman of Mediterranean de- scent presents because of fatigue, arthralgias, discomfort in her right upper abdominal quad- rant, and polyuria. Laboratory tests are remark- able for elevated glucose level, elevated biliru- bin, low hemoglobin, elevated reticulocytes, and increased transferrin saturation. Cardiac testing shows moderate restrictive cardiomyop- athy. She frequently has required blood trans- fusions throughout her life. Which hereditary disorder does this patient most likely have? (A) Absence of the hemoglobin a-chain (B) Absence of the hemoglobin b-chain (C) Mutation resulting in increased absorption of dietary iron (D) Mutations in the gene encoding ankyrin (E) Mutations resulting in copper accumula- tion
A premature neonate was admitted to the neonatal intensive care unit. The blood bank performed a neonatal antibody profile consisting of blood type, antibody screen, and a direct antiglobulin test. The neonate phenotypes as group A, D-positive.the antibody screen is negative. The doctor placed a transfusion order for 20 mL of RBCs. 1. Can this neonate receive type-specific RBC products? 2. If the baby had a passive maternal ABO antibody, what blood group would be compatible with the neonate?
