The PNP assesses a 4‑year‑old child with unexplained pallor, intermittent fevers, multiple bruises, hepatosplenomegaly, and lymphadenopathy. The child also reports, “I hurt,” and is limping or refusing to walk. The PNP would have which of the following at the top of her differential diagnosis list?

Please match the etiology to the disease. 

The NP student is seeing a patient with anemia. The student tells the preceptor that they want to order iron studies on the patient. The preceptor asks the student what the lab studies will help them determine. The NP student states that, in addition to iron levels, the labs will report: [answer1], which is an iron storage protein, storing iron. [answer2], which is responsible for binding  and transporting iron. 

Please choose if the disease results in a bleeding or clotting disorder. 

A 28‑year‑old patient presents to the FNP complaining of “weird lumps” on the left side of her neck that have been present for 3 months. She reports unintentional weight loss, drenching night sweats, and pruritus. The FNP palpates nontender, enlarged cervical and axillary lymph nodes on the left side. The patient’s spleen is also enlarged. A chest x‑ray reveals a mediastinal mass. CBC shows leukocytosis with elevated eosinophils, and her ESR is elevated. The FNP would be most concerned the patient has:

A person arrives in the clinic reporting 4 days of nausea, vomiting, and diarrhea. The hematocrit is extremely high, at 61%. The NP suspects:

A 5-year-old boy is brought to urgent care and seen by a PNP because of the new onset of a fine, dark, pinpoint rash most prominent on his lower legs. He was last seen 2 weeks ago for an uncomplicated viral upper respiratory infection. He has no other symptoms besides the rash. The PNP observes a petechial rash and several healing bruises. CBC results: WBC: 6.5 (normal) Hgb: 13.0 (normal) Hct: 38% (normal) Platelets: 50,000 (low) MCV: 84 (normal) WBC differential: normal The PNP knows the most likely physiological cause of the boy’s rash is:

Which blood component is responsible for lysis and the breakdown of blood clots?

A nonconducting sphere of radius 3 cm has a total charge q1 = -10 pC distributed uniformly throughout its volume.  At the center of the sphere is a point charge q2 = 7 pC. Point P is located on the x-axis at x = 2 cm.  What is the magnitude of the E-field at point P? (select closest answer)

An electron (m = 9.11 x 10-31 kg, q= -1.6 x 10-19 C) moves at 3 x 105 m/s parallel to an electric field of  5.7 x 10-6 N/C in the positive x-direction.  What distance has the electron moved after 0.1 seconds?
