CCRN AACN Test Questions with Correct
Answers
A patient with a history of bronchogenic carcinoma is admitted with respiratory failure.
the patient is intubated and on mechanical ventilation. the patient develops lethargy,
headache, slight confusion and abdominal cramping urinary output is decreasing and
significant lab data includes
Serum Na+ 127
Serum osmolality 270
urine specific gravity elevated
Initiation of fluid restriction -
this pt has risk factors signs and symptoms of SIADH
fluid restriction slows glomerular filtration and blood flow enhances proximal reabsorption of
sodium and water increases aldosterone secretion and enhances distal tubule sodium
reabsorption. chemo may alleviate some of the water retention caused by some cancers but
non will completely inhibit ADH secretions. three percent saline administration in severe
case only
A pt is being admitted in HHS with dehydration and a serum glucose level of 836 mg/dl.
Which additional laboratory findings should the nurse anticipate?
> elevated BUN > Elevated creatinine >elevated osmolality
HHNS - Hyperosmolar hyperglycemic nonketonic state
A 49 year old patient male recently admitted with an inferiors wall MI resulting from
100% occlusion of the right coronary artery (RCA). The 12 lead ECG reveals ST
