56 A patient is diagnosed with diabetes insipidus after transsphenoidal resection of
a pituitary adenoma. What should the nurse consider as a sign of improvement?
Serum sodium of 120 mEq/L
Urine specific gravity of 1.001
Fasting blood glucose of 80 mg/dL
Serum osmolality of 290 mOsm/kg
Give this one a try later!
, Serum osmolality of 290 mOsm/kg
Rationale:
Laboratory findings in diabetes insipidus include elevated serum osmolality
and serum sodium and decreased urine specific gravity. Normal serum
osmolality is 285 to 295 mOsm/kg, normal serum sodium is 136 to 145
mEq/L, and normal specific gravity is 1.005 to 1.030. High blood glucose
levels occur with diabetes.
59 Benzodiazepines are indicated in the treatment of delirium caused by which
condition?
Polypharmacy
Cerebral hypoxia
Alcohol withdrawal
Electrolyte imbalances
Give this one a try later!
Alcohol withdrawal
Rationale:
Benzodiazepines can be used to treat delirium associated with sedative
and alcohol withdrawal. However, these drugs may worsen delirium caused
by other factors and must be used cautiously. Polypharmacy, cerebral
hypoxia, and electrolyte imbalances are not treated with benzodiazepines.
45 The immunologic mechanisms involved in acute poststreptococcal
glomerulonephritis include:
deposition of immune complexes and complement along the GBM.
tubular blocking by precipitates of bacteria and antibody reactions.
thickening of the GBM from autoimmune microangiopathic changes.
destruction of glomeruli by proteolytic enzymes contained in the GBM.
Give this one a try later!
, deposition of immune complexes and complement along the GBM.
Rationale:
All forms of immune complex disease are characterized by an
accumulation of antigens, antibodies, and complement in the glomeruli,
which can result in tissue injury. The immune complexes activate
complement. Complement activation results in the release of chemotactic
factors that attract polymorphonuclear leukocytes, histamine, and other
inflammatory mediators. The result of these processes is glomerular injury.
46.8. Which nursing interventions should a nurse implement when removing an
indwelling urinary catheter in an adult patient? (Select all that apply.)
1. Attach a 3-mL syringe to the inflation port.
2. Allow the balloon to drain into the syringe by gravity.
3. Initiate a voiding record/bladder diary.
4. Pull the catheter quickly.
5. Clamp the catheter before removal.
Give this one a try later!
2, 3 no evidence to support clamping catheters before removal
true or false, patient to patient transmission of infection cannot occur if gloves are
routinely used
Give this one a try later!
false- Although gloves are an additional tool to decrease the spread of
infection from patient to patient, touching gloves with unclean hands as
you put them on contaminates the gloves so that they are no longer clean.
, 57 The nurse would expect what assessment finding in a patient admitted with a
left-sided stroke?
Impulsivity
Impaired speech
Left-side neglect
Short attention span
Give this one a try later!
Impaired speech
Rationale:
Manifestations of left-sided brain damage include right hemiplegia,
impaired speech/language, impaired right/left discrimination, and slow and
cautious performance. Impulsivity, left-sided neglect, and short attention
span are all manifestations of right-sided brain damage.
46.9. Which nursing intervention decreases the risk for catheter-associated urinary
tract infection (CAUTI)?
1. Cleansing the urinary meatus 3 to 4 times daily with antiseptic
solution
2. Hanging the urinary drainage bag below the level of the bladder
3 Emptying the urinary drainage bag daily
4. Irrigating the urinary catheter with sterile water
Give this one a try later!

44 The nurse obtained a urine specimen from a patient. What result should the
nurse recognize as an abnormal finding?
pH of 6.0
