Altering the pH of the gastric secretions through the use of H2 receptor
antagonists, antacids, and proton pump inhibitors contributes to which potential
complication?
A.
Pulmonary embolism
B.
Pneumonia
C.
Stress ulcer
D.
Acid-base imbalance - ANSWER-B. Pneumonia
,Gastric colonization is likely with a gastric pH of greater than 4. Pneumonia rates
of patients receiving mechanical ventilation correlate directly with increased
gastric pH levels. This is one of the risks of the use of H2 receptor antagonists,
antacids, and proton pump inhibitors to prevent stress ulcers in intubated patients.
You have a 76-year-old patient that is on a norepinephrine gtt. You notice the
patient is complaining of severe pain and that the area around her IV is becoming
translucent, cool to touch, and discolored. What stage is this and what medication
should you administer to prevent extravasation?
A.
Stage 1, phentolamine
B.
Stage 4, hyaluronidase
C.
Stage 4, phentolamine
D.
Stage 3, dexrazoxane - ANSWER-C. Stage 4, phentolamine
The patient is experiencing Stage 4 infiltration and is on a vasopressor gtt;
therefore, phentolamine is the drug of choice to counteracts the effects of
infiltration/extravasation.
Which of the following solutions would be most appropriate for initial fluid
resuscitation of a patient with severe hypovolemia caused by several days of
diarrhea and vomiting?
A.
,An isotonic crystalloid
B.
A hypotonic crystalloid
C.
A hypertonic crystalloid
D.
A colloid - ANSWER-A. An isotonic crystalloid
In this situation, the intravascular and the interstitial spaces would be depleted. The
priority is the intravascular space, which would be replaced best with isotonic
solution. Because isotonic fluids equilibrate across all spaces, the interstitial space
also would be replaced.
Consider: What did the patient lose? Crystalloid and electrolyte. Then ask: Which
crystalloid would replace the intravascular and interstitial spaces? An isotonic
crystalloid. Electrolytes would be added.
A 28-year-old man is admitted with bowel perforation. His blood pressure is 92/64
mm Hg, heart rate is 116 beats/min and regular, respiratory rate is 22 breaths/min
and regular, and urine output has only been 20 ml since being admitted 3 hours
ago. Mucous membranes are dry, and there is poor skin turgor. Based on this
information, you would expect his pulmonary artery occlusive pressure to be:
A.
4 mm Hg.
B.
8 mm Hg.
C.
, 12 mm Hg.
D.
16 mm Hg. - ANSWER-A. 4 mm Hg.
This assessment reveals dehydration (hypotension, tachycardia, oliguria, dry
mucous membranes, and poor skin turgor). A pulmonary artery occlusive pressure
(PAOP) of 4 mm Hg would correlate with the physical assessment. Normal PAOP
is 12 to 15 mm Hg.
Clinical indications of dehydration are present in the case study. Choose the value
below normal. Choose 4 mm Hg.
A patient with acute kidney injury has the following arterial blood gas results:
pH7.32Paco235 mm HgHCO318 mEq/L
This acid-base imbalance is the result of the inability of the kidney to:
A.
excrete acid by-products of metabolism.
B.
excrete carbon dioxide.
C.
excrete bicarbonate ions.
D.
excrete calcium ions. - ANSWER-A. excrete acid by-products of metabolism.
