A patient had a pulmonary artery catheter, and the following values were obtained on the initial shift assessment:
Blood pressure 82/48, heart rate 126 beats/minute, pulmonary artery pressure 22/10, central venous pressure (CVP) 1 mmHg, pulmonary artery occlusion pressure 4 mmHg, cardiac output 3 ...
A patient had a pulmonary artery catheter, and the following
values were obtained on the initial shift assessment:
Blood pressure 82/48, heart rate 126 beats/minute,
pulmonary artery pressure 22/10, central venous pressure
(CVP) 1 mmHg, pulmonary artery occlusion pressure 4
mmHg, cardiac output 3 L/minute, and systemic vascular
resistance 1,600 dynes/s/cm-5
This patient requires the administration of:
(A) a fluid bolus of 500 mL of 0.9 normal saline.
(B) dopamine at 5 mcg/kg/min.
(C) dobutamine (Dobutrex) at 10 mcg/kg/min.
(D) nitroprusside (Nipride) at 1 mcg/kg/min. - ✔ ✔ (A) a
fluid bolus of 500 mL of 0.9 normal saline.
A patient had an episode of chest pain at rest with ST
elevation on the ECG. The chest pain was relieved, and the ST
segments were normalized after the administration of
nitroglycerin sublingual. This patient most likely had:
(A) stable angina.
(B) an ST-elevation myocardial infarction.
(C) Prinzmetal's, or variant, angina.
,(D) Wellens syndrome. - ✔ ✔ (C) Prinzmetal's, or variant,

A patient has a history of chronic respiratory failure
secondary to COPD and now has acute respiratory failure
secondary to pneumonia. Upon arrival at the critical care
unit, his ABGs were a pH of 7.29, a PaCO2 of 77, a PaO2 of 51,
and an HCO3 of 31. He is receiving noninvasive ventilation
with settings that read as follows: FiO2 0.40, IPAP 12 cm,
and EPAP 5 cm. After 1 hour of therapy, the patient's ABG
results are a pH of 7.20, a PaCO2 of 89, a PaO2 of 48, and an
HCO3 of 32.
What is the correct evaluation of this data?
(A) Alveolar hyperventilation is getting worse; the BiPAP
settings need adjustment.
(B) Metabolic acidosis is worse; the FiO, needs to be
increased.
(C) Alveolar hypoventilation is getting worse; the patient
needs to be intubated.
(D) The pH is acceptable for a patient with COPD; continue
the current therapy. - ✔ ✔ (C) Alveolar hypoventilation is
getting worse; the patient needs to be intubated.
A patient was admitted with diabetic ketoacidosis, a serum
glucose of 450 mg/dL, and a pH of 7.12. An IV insulin
,infusion was initiated. The latest serum glucose is 160
mg/dL (it was 275 mg/dL 1 hour previously), the anion gap
is 22 mEq/dL, and the venous CO2 is 14 mmol/kg. Which of
the following interventions is most appropriate at this time?
(A) Discontinue the insulin infusion.
(B) Lower the insulin infusion dose.
(C) Administer sodium bicarbonate.
(D) Increase the insulin infusion dose. - ✔ ✔ (B) Lower
the insulin infusion dose.
A patient who has a complex diabetic ulcer is receiving
negative-pressure wound therapy. Which of the following is

(C) Flush the tubing daily.
(D) Change the wound VAC canister when it is full. - ✔ ✔
(D) Change the wound VAC canister when it is full.

has sustained A-waves on the intracranial pressure (ICP)
monitor. Which of the following interventions is
contraindicated for this patient?
, (A) Discontinue opiate and sedating drugs.
(B) Administer mannitol.
(C) Infuse isotonic solutions.
(D) Drain CSF from the ventricular catheter. - ✔ ✔
A 22-year-old male patient, with a known history of Wolff-

nurse should anticipate the administration of which of the
following medications?
(A) adenosine (Adenocard)
(B) diltiazem (Cardizem)
(C) esmolol (Brevibloc)
(D) digoxin (Lanoxin) - ✔ ✔
A 23-year-old patient with head trauma begins to have
polyuria with a urine output of 900 mL in 1 hour, a urine
specific gravity of 1.001, and an elevated serum osmolality.
Which of the following interventions would be expected for
this patient?
(A) Administer 3% saline.
(B) Administer phenytoin.
(C) Administer Pitressin.
