Nur 222 Latest Questions and Correct Solutions
1) Which factor is most important in the regulation of capillary oncotic pressure?
Albumin
1) A 77-year-old female has severe diarrhea during her hospital stay. Which best describes
the risk the patient most likely faces due to the diarrhea?
Risk for isotonic fluid volume deficit.
A patient is diagnosed with hyper-aldosterone secretion. Which change does the
nurse most likely expect to occur?
Decreased serum potassium levels.
A patient is brought to the ED with shortness of breath. On assessment, the nurse notes a
full bounding pulse, peripheral edema, and crackles in the lungs bilaterally. The nurse
understands the patient most likely has developed which condition?
Hypervolemia.
Describe the expected effects of renin-angiotensin-aldosterone system activation. What
would stimulate this system to be activated?
Low BP, low effective circulating volume, low serum sodium levels, and/or high serum
potassium levels would stimulate RAAS. Activation of RAAS will increase BP via
vasoconstriction, sodium/fluid retention by the kidneys, and will also cause kidneys to increase
urinary excretion of potassium.
Which patient is most at risk to develop hypervolemic hypernatremia?
, Patient receiving 3% sodium chloride intravenous fluid
A patient with GI bleeding is brought to the emergency department. Blood pressure is
78/50 mmHg, heart rate is 112 bpm, and peripheral pulses are 1+. Laboratory results
reveal serum sodium 142 mEq/L and serum osmolality is 282 mOsm/L. Which condition
has the patient developed?
Isotonic hypovolemia.
A patient is diagnosed with hypervolemic hyponatremia. Which lab value does the nurse
expect to observe?
Sodium 125 mEq/L.
1) A patient has hyperactive bowel sounds, a fast heart rate, and the nurse observes peaked
T-waves on an electrocardiogram (EKG). Which potassium level does the nurse expect to
observe?
5.9 mEq/L.
1) Which factor is directly related to glomerular filtration rate (GFR) and therefore has
the greatest influence on GFR?
A. Renal blood flow (perfusion).
1) A patient is diagnosed with acute kidney injury (AKI). The nurse knows which
electrolyte imbalance is most likely to occur in this patient?
A. Hyperkalemia.
