Question 8

A nurse practitioner is explaining to a 40 yo male pt the damage that Mycobacterium tuberculosis could do to lung tissue. Which of the following phenomena would underlie the NP explanation?

Tissue destruction results from neutrophil deactivation.

Nonspecific macrophage activity leads to pulmonary tissue destruction and resulting hemoptysis.

Macrophages are unable to digest the bacteria, resulting in immune granulomas.

Neutrophils are ineffective against the Mycobacterium tuberculosis antigens

The couple have approached their NP with this request and are seeking clarification of exactly why stem cells are valuable.How can the nurse practitioner best respond to the couple’s inquiry?

Stem cells can help correct autoimmune diseases and come congenital defects

Stem cells can be used to regenerate damaged organs should the need ever arise

Stem cells can be used as a source of reserve cells for the entire blood production system

Stem cells can help treat some cancers and anemias, but they must come from your child himself or herself"

The lymph nodes involved are located in a large number of locations in the lymphatic system.

The presence of Reed-Sternberg cells has been confirmed.

The woman complains of recent debilitating fatigue.

Question 14

A NP is providing prenatal care and eduction for a first-time expectant mother, 22 wks gest, who has a diagnosis of a STD. Which of the following statements by the expectant mother demonstrates an adequate understanding of vertical disease transmission and congenital infections?

“Gonorrhea and chlamydia pose the greatest risks of transmission from mother tochild.”

“I know that my baby will need observation for HIV signs and symptoms in the weeks following my delivery.”

“My baby could become infected either across the placenta or during the birth itself.”

“Prophylactic immunization will reduce my baby's chance of being born with an illness.”

Question 15

A 71 yo male pt w/ a hx of MI and peripheral vascular disease has been advised by his NP to begin taking 81 mg of ASP once daily.Which of the underlying rationale for the NP suggestion?

Platelet aggregation can be precluded through inhibition of prostaglandin production by aspirin.Aspirin helps to inhibit adenosine disphosphate (ADP) action and minimizes platelet plug formation.

Aspirin can reduce unwanted platelet adhesion by inhibiting thromboxane A2 (TXA2) synthesis.Aspirin inhibits the conversion of fibrinogen into fibrin and consequent platelet plug formation

Question 16

Which of the following statements most accurately conveys an aspect of lymphatic system activity?

B and T lymphocyte development begins in the bone marrow and ends in the peripheral lymphoid structures.

B cells and macrophages are released from the bone marrow in their completed state.

Stem cells in the lymph nodes initiate and regulate the process of white cell synthesis.

Leukocytes bypass vascular circulation and are distributed instead by the lymphatic system.

Question 17

A 23 yo man has received a recent dx of appendicitis following 24 hrs of acute abd pain. The NP providing care for the man is explaining that while it is unpleasant, the inflammation of his appendix is playing a role in his body’s fight against the underlying infectious process.Which of the following teaching points should the NP eliminate from his teaching for the patient?

“Inflammation can help to remove the body tissue cells that have been damaged by infection.”

“Inflammation will start your body on the path to growing new, healthy tissue at thesite of infection.”

“Inflammation helps your body to produce the right antibodies to fight the infection.”

“Inflammation ultimately aids in eliminating the initial cause of the cell injury in your appendix.”

Question 18

A 66yo female pt has presented to the ED w/ several months of intermittently bloody stools that has recently become worse. The woman has since been diagnosed w/ a GI bleed secondary to overuse of NSAIDs that she takes for her arthritis. The health care team would realize that which of the following situations is most likely?

The woman has depleted blood volume due to her ongoing blood loss.
She will have iron deficiency anemia due to depletion of iron stores.
The patient will be at risk for cardiovascular collapse or shock.
She will have delayed reticulocyte release.

Question 19

A 40 yo woman experiences severe seasonal allergies has been referred by her family physician to an allergist for weekly allergy injections. The woman is confused as to why repeated exposure to substances that set off her allergies would ultimately benefit her. Which of the following phenomena best captures the rationale for allergy desensitization therapy?

Repeated exposure to offending allergens binds the basophils and mast cells that mediate the allergic response.
Allergens in large, regular quantities overwhelm the IgE antibodies that mediate the allergic response.
Repeated exposure stimulates adrenal production of epinephrine, mitigating the allergic response.
Injections of allergens simulate production of IgG, combining with the antigens to prevent activation of IgE antibodies.

Question 20

A 44 yo female patient presents to the ED with abnormal bleeding and abd pain that is later attributed to gallbladder disease.Which of the following diagnoses would the medical team be most justified in suspecting as a caus of the patient’s bleeding?

Question 21

A NP is teaching her colleagues about the role of cytokines in a variety of pathologies. Which of the following teaching points best captures an aspect of the functions and nature of cytokines?

“A particular cytokine can have varied effects on different systems, a fact that limits their therapeutic use.”

“Cytokine production is constant over time, but effects are noted when serum levels cross a particular threshold.”

“Most cytokines are produced by granular leukocytes, and different cells are capable of producing the same cytokine.”

“Cytokine actions are self-limiting in that activation of one precludes activation of other cytokines with similar actions.”

Question 22

A 24 yo woman presents with fever and painful, swollen cervical lymph nodes. Her blood work indicates neutrophilia with a shift to the left. She most likely has:

a mild parasitic infection.
a severe bacterial infection.
a mild viral infection.
