The licensed practical/vocational (LPN/VN) nurse is caring for a client with cardiac arrest
and assisting the registered nurse (RN) in identifying priorities and delegation. As the
LPN/VN assists with assigning roles to other staff, this is demonstrating which leadership
style?
A. Authoritative
B. Situational
C. Democratic
D. Laissez-faire
Authoritative
Rationale:
Authoritative leadership is demonstrated in this situation as the nurse assists with the delegation
and provides directives to accomplish tasks. This is an appropriate leadership style in an
emergency where one individual assigns tasks/roles to decrease confusion and chaos in an
emergent situation.
What is the normal level of creatinine in a healthy adult male?
A. 0.4 to 0.8 mg/dL
B. 0.1-0.4 mg/dL
1
,C. 0.6-1.2 mg/dL
D. 1.5-2.0 mg/dL
0.6-1.2 mg/dL
Rationale:
Creatinine values reflect both the amount of muscle a person has and their amount of kidney
function. Hence, the levels are slightly lower in women due to lesser muscle mass. Most men
with normal kidney function have 0.6 to 1.2 milligrams/deciliters (mg/dL) of creatinine. Most
women with normal kidney function have between 0.5 to 1.1 mg/dL of creatinine.
The nurse is caring for a client who has a serum calcium level of 13.2 mg/dL(9-10.5 mg/dL).
Which of the following medications would be expected orders for this condition?
Select all that apply.
Phosphorus
Calcitonin
Vitamin D
IV calcium gluconate
Glucocorticoids
Phosphorus
Calcitonin
Glucocorticoids
Rationale:
The normal serum calcium level is 8.4-10.2 mg/dL. This client has a high serum calcium level
(hypercalcemia). Phosphorus is a medication that the nurse would expect to administer to treat
2
,hypercalcemia. Phosphorus and calcium have an inverse relationship, so by increasing the serum
level of phosphorus the nurse can decrease the serum level of calcium. Oral phosphate is the
preferred method of administering phosphorus. If given IV, calcium phosphate forms and
precipitates in the tissues. This “precipitation phenomenon” reduces serum calcium levels very
quickly.
Calcitonin is a medication that the nurse would expect to administer to treat hypercalcemia.
Calcitonin is a thyroid hormone that decreases the plasma calcium level by inhibiting bone
resorption and lowering the serum calcium concentration.
Glucocorticoids are steroids that can be used to treat a variety of conditions, including
hypercalcemia associated with certain cancers. Glucocorticoids work by inhibiting the activity of
cells that break down bone and release calcium into the blood.
The nurse is reviewing labs for a patient with a serum potassium level of 3.3 mg/dL(3.5-5
mEq/L). Which action would the nurse recognize as the highest priority?
A. Educate the patient on potassium-rich foods
B. Implement telemetry monitoring
C. Obtain an order for STAT IM KCl
D. Assess the patient’s neurological status
Implement telemetry monitoring
Rationale:
The normal range for serum potassium is between 3.5-5 mg/dL, so this patient’s level is low.
Hypokalemia can lead to life-threatening cardiac arrhythmias. Of the options provided, initiating
telemetry monitoring would be the highest priority in order to assess the patient’s heart function
and monitor for any changes.
The nurse is caring for a client with acute renal failure. Which of the following laboratory
results should be reported to the primary healthcare provider (PHCP)?
3
, A. Blood urea nitrogen 20 mg/dL
B. Serum potassium 6 mEq/L
C. Venous blood pH 7.30
D. Hemoglobin of 10.3 mg/dL
Serum potassium 6 mEq/L
Rationale:
Acute renal failure can cause a significant imbalance in lab values. Although all of the lab results
listed are abnormal, the elevated potassium level is a life-threatening finding.
Although all of these findings are abnormal, elevated potassium is a life-threatening finding and
must be reported immediately. The normal potassium is 3.5 - 5.0 mEq/l
The BUN level should be 10 to 20 mg/dL.
Venous blood pH should be 7.31 to 7.41.
Normal hemoglobin levels differ based on age, sex, and general health. The normal range for
hemoglobin is 14 to 17.5 grams per deciliter for men. For women, 12.0 to 16 grams per deciliter.
The nurse cares for a client with a sodium 130 mEq/dl(135-145 mEq/L). Which of the
following medications may cause this abnormality? Select all that apply.
Spironolactone
Hydrochlorothiazide
Prednisone
Sodium polystyrene
Tolvaptan
