Answer 1

1. The nurse is educating the parents of a toddler newly diagnosed with Cystic Fibrosis. the nurse knows that cystic fibrosis:

A. is a recessive genetic disorder: It is a progressive recessive genetic disease (answer)

B. sodium and chloride will normalize as the toddler grows- This toddler may have abnormal sodium and chloride levels and this is a progressive disease, so as the age increases, severity of disease increases . wrong option

C. any dietary changes can result in worsening cardiac function- Cystic fibrosis is a multisystem disorder. It affects the nutrient absorption . Respiratory changes often lead to worsening of cardiac function. wrong option.

D. respiratory complications are managed with yearly visits to the pulmonologist.- Respiratory complications worsens as age increases and also respiratory failure occur. Quarterly visits to care center is recommended. wrong option.

2. a client diagnosed with CKD has low erythropoietin level. the nurse knows the client is at a risk for

which condition?

A. anemia- Patient with low erythropoeitin level with CKD is affected by anemia often. A normal anemic patient with normal renal function has high erythropoeitin level .(answer)

B. leukocytosis -Leucocytosis can occur in these patients but that is due to their renal insufficiency and not due to low erythropoeitin.wrong option

C. hypercalcemia- CKD patients have hypercalcemia but due to increased parathyroid hormone secretion not due to low erythropoeitin level.wrong option

D. thrombocytosis- Patient with CKD have thrombocytosis but due to drugs and dialysis . wrong answer.

3. which factor does NOT affect arteriole size and peripheral resistance?

A. Histamine- This causes vasoconstriction .wrong option

b. Calorie intake- This does NOT affect arteriole size and peripheral resistance. If the person has obesity only there may be changes in blood pressure .(answer)

c. Nitrous oxide- This increases atrial pressure and peripheral pulmonary resistance. wrong option.

d. SNS hormones- Peripheral resistance is affected by SNS .so wrong option.

4. a client has a total serum calcium level of 7.5 mg/dL . during assessment, the nurse finds which clinical manifestatjon associated with the calcium level?

Normal calcium level is  8.5 to 10.5 mg/dl.

A. decreased oxygen saturation levels - This level of calcium doesn't affect the oxygen saturation. wrong option

B. heart rate of 120 beats/minute associated with diaphoresis - Hypocalcemia patients have bradycardia.wrong option

C. intermittent muscle spasms and numbness around her mouth- This occurs in hypoparathyroidism causing low calcium levels in body .(answer)

D .difficulty arousing the client who is disoriented in time and place- Hypercalcemia can cause confusion.wrong option
