You are admitting a patient with complaints of abdominal
pain, nausea, and
Vomiting. A proximal bowel obstruction is suspected.
Which acid-base
Imbalance do you anticipate in this
patient?
A. Metabolic acidosis
B. Metabolic alkalosis
C. Respiratory acidosis
D. Respiratory alkalosis - ANSWER -B. Metabolic alkalosis
Rationale: Because gastric secretions are rich in HCl acid, the
patient who is vomiting will lose a significant amount of gastric
acid and be at an increased risk for metabolic alkalosis.
Which action is most important for the nurse to take when
caring for a patient
with a subclavian triple-lumen
catheter?
,A. Change the injection cap after the administration of IV
medications.
B. Use a 5-mL syringe to flush the catheter between
medications and after use. C. During removal of the catheter,
have the patient perform the Valsalva maneuver.
D. If resistance is met when flushing, use the push-pause
technique to dislodge the clot. - ANSWER -C. During removal of
the catheter, have the patient perform the Valsalva maneuver.
Rationale: The nurse should withdraw the catheter while the
patient performs the Valsalva maneuver to prevent an air
embolism. Injection caps should be changed at regular
intervals but not routinely after medications. Flushing should
be performed with at least a 10-mL syringe to avoid excess
pressure on the catheter. If resistance is encountered during
flushing, force should not be applied. The push-pause method
is preferred for flushing catheters but not used if resistance is
encountered during flushing.
Which nursing intervention is most appropriate when caring
for a patient with
dehydration?
A. Monitor skin turgor every shift.
B. Auscultate lung sounds every 2 hours.
C. Monitor daily weight and intake and output.
D. Encourage the patient to reduce sodium intake. - ANSWER -
C. Monitor daily weight and intake and output.
,Measuring weight is the most reliable means of detecting
changes in fluid balance. Weight loss would indicate the
dehydration is worsening, whereas weight gain would indicate
restoration of fluid volume.
You are caring for a patient receiving calcium carbonate for
the treatment of
osteopenia. Which serum laboratory result would you
identify as an adverse
effect related to this
therapy?
A. Sodium falling to 138 mEq/L
B. Potassium rising to 4.1 mEq/L
C. Magnesium rising to 2.9 mg/dL
D. Phosphorus falling to 2.1 mg/dL - ANSWER -D. Phosphorus
falling to 2.1 mg/dL
Calcium has an inverse relationship with phosphorus in the
body. When phosphorus levels fall, calcium rises, and vice
versa. Because hypercalcemia rarely occurs as a result of
calcium intake, the patient's phosphorus falling to 2.1 mg/dL
(normal, 2.4-4.4 mg/dL) may be a result of the phosphate-
binding effect of calcium carbonate.
You are caring for a patient admitted with a diagnosis of
chronic obstructive pulmonary disease (COPD) who has the
following arterial blood gas results: pH 7.33, PaO2 47 mm Hg,
, PaCO2 60 mm Hg, HCO3 32 mEq/L, and O2 saturation of 92%.
What is the correct interpretation of these results?
A. Fully compensated respiratory alkalosis
B. Partially compensated respiratory acidosis
C. Normal acid-base balance with hypoxemia
D. Normal acid-base balance with hypercapn - ANSWER -B.
Partially compensated respiratory acidosis
Rationale: A low pH (normal, 7.35-7.45) indicates acidosis. In a
patient with respiratory disease such as COPD, the patient
retains carbon dioxide (normal, 35-45 mm Hg), which acts as an
acid in the body. For this reason, the patient has respiratory
acidosis. The elevated HCO3 indicates a partial compensation
for the elevated CO2.
The nurse on a medical-surgical unit identifies which
patient as having the
highest risk for metabolic
alkalosis?
A. A patient with a traumatic brain injury
B. A patient with type 1 diabetes mellitus
C. A patient with acute respiratory failure
D. A patient with nasogastric tube suction - ANSWER -D. A
patient with nasogastric tube suction
Rationale: Excessive nasogastric suctioning may cause
metabolic alkalosis. Brain injury may cause hyperventilation
