C: Decreased GH levels with an oral glucose challenge test. D: A serum somatomedin C (insulin-like growth factor-1 [IGF-1]) of more than 300ng/ml.

D: A serum somatomedin C (insulin-like growth factor-1 [IGF-1]) of more than 300ng/ml. Normal response GH secretion is stimulation of liver to produce somatomedin C or IGF-1 which stimulates growth of bones & soft tissues. The increased levels of somatomedin C normally inhibit GH, but in acromegaly the pituitary gland secretes GH despite elevated IGF-1 levels. When both GH and IGF-1 levels are increased, overproduction of GH is confirmed.

A client arriving in the emergency department (ED) is receiving cardiopulmonary resuscitation from paramedics, who are giving ventilations through an endotracheal (ET) tube that they placed in the client's home. During a pause in compressions, the cardiac monitor shows narrow QRS complexes and a heart rate of 55 beats/ minute with a palpable pulse. What action should the nurse take first?

B: Check ET tube placement. Rationale: ET tube placement should be confirmed as soon as the client arrives in the ED. Once the airway is secured, oxygenation and ventilation should be confirmed using an end-tidal carbon dioxide monitor and pulse oximetry. Next, the nurse should make sure I.V. access is established. If the client experiences symptomatic bradycardia, atropine is administered to a total of 3 mg. Then the nurse should try to find the cause of the client's arrest by obtaining an ABG sample. Amiodarone is indicated for ventricular tachycardia, ventricular fibrillation, and atrial flutter- not symptomatic bradycardia.

B: Corticosteroids Rational: Corticosteroids are used in initial treatment of idiopathic thrombocytopenic purpura (ITP) because they suppress the phagocytic response of splenic macrophages, decreasing platlet destruction. They also depress autoimmune antibody formation and reduce capillary fragility and bleeding time. All of the other therapies may be used but only in patients who are unresponsive to corticosteroid therapy.

A patient is scheduled for chemotherapy and has a WBC of 2100 cells/mm3 with 28% segmented neutrophils and 18% bands along with 42% lymphocytes. He is informed that chemotherapy will be delayed and he is to be admitted to the hospital. The reason for this is most likely which of the following? A: His white count is too low B: His absolute neutrophil count (ANC) is less than 1000 C: His absolute neutrophil count is greater than 5000 D: None of the above, his ANC is adequate for treatment

B: His absolute neutrophil count (ANC) is less than 1000 28+18 = 46% 46% x 2100 = 966 cells/mm

In a patient with an elevated serum cortisol, the nurse would expect other laboratory findings to reveal: A: Hyponatremia B: Hypokalemia C: Hypoglycemia D: Decreased serum triglycerides

During physical assessment of a patient with thrombocytopenia, the nurse would expect to find A: sternal tenderness. B: Petechiae and purpura. C: Jaundiced sclera and skin. D: Tender, enlarged lymph nodes.

B: Petechiae and purpura. Rational: Petechiae are small, flat, red or reddish brown pinpoint microhemorrhages that occur on the skin when platelet levels are low; when they are numerous, they group, causing reddish bruises known as purpura. Jaundice occurs in accumulation of bile pigments from red blood cells (RBCs). Enlarged, tender lymph nodes are associated with infection, and sternal tenderness is associated with leukemias.

A primary reason that the normal immune response fails to contain HIV infection is that A: CD8+ T cells are stimulated, causing suppression of B lymphocyte activity B: The virus inactivates B lymphocytes, preventing the production of HIV antibodies C: Activated CD4+ T cells drawn to HIV become infected & support viral replication D: Monocytes ingest infected cells, differentiate into macrophages and shed viruses in body tissues

C: Activated CD4+ T cells drawn to HIV become infected & support viral replication The virus does not stimulate CD8+ T cells and B lymphocytes are functional early in the dz, as evidence by positive antibody titers against HIV. Monocytes do ingest infected cells & may become sites of HIV replication & spread the virus to other tissue, but this does not make the immune response ineffective.

Cerebral hemorrhage may be fatal, and evaluation of mantal status for CNS alterations to identify CNS bleeding is very important. Fever is not a common finding in thrombocytopenia. Protection from injury to prevent bleeding is an important nursing intervention, but strict bed rest is not indicated. Oral care is performed very gently with minimal friction and soft swabs.

D: Increase in urine osmolality.

Which is the initial treatment goal for cardiogenic shock? A: Correct hypoxia B: Prevent infarction C: Correct metabolic acidosis D: Increase myocardial oxygen supply

D: Increase myocardial oxygen supply Rationale: A balance must be maintained between oxygen supply and demand. In a shock state, the myocardium requires more oxygen. If it cant get more oxygen, the shock worsens. Increasing the oxygen will also play a large role in correcting metabolic acidosis and hypoxia. Infarction typically causes the shock state, so prevention isn't an appropriate goal for this condition.

The hormone that increases Ca resorption from the bones & kidney & increases absorption for the intestine is A: TSH B: Calcitonin C: Aldosterone D: Parathyroid hormone

D: Parathyroid hormone Parathyroid hormone is responsible for maintaining adequate serum Ca levels & raises Ca levels by stimulating Ca resorption from the bone, absorption from the intestines & retention by the kidney. Calcitonin secreted by the thyroid gland has the opposite effect.
