Which of the following signs is LEAST suggestive of a diabetic
emergency?
• A:Fruity breath odor
• B:Bradycardia
• C:Combativeness
• D:Tachycardia -------------------------------------You selected B; This is
correct!
Reason:Bradycardia is not commonly associated with either
hyperglycemia or hypoglycemia. Tachycardia and combativeness can
occur in patients with hyperglycemia or hypoglycemia. A fruity breath
odor is noted exclusively in patients with diabetic ketoacidosis
(diabetic coma, hyperglycemic crisis).
A 46-year-old man presents with generalized weakness and shortness
of breath after he was bitten on the leg by a rattlesnake. His blood
pressure is 106/58 mm Hg and his pulse rate is 112 beats/min. In
addition to supplemental oxygen, further treatment for this patient
should include:
,• A:ice packs to the wound and splinting.
• B:proximal arterial constricting band and splinting.
• C:splinting and lowering of the affected part.
• D:elevation of the affected part and ice packs. -------------------------------
------The correct answer is C;
Reason:Care for a patient with a bite from a pit viper (rattlesnake,
copperhead, water moccasin) includes keeping the patient calm,
administering supplemental oxygen, splinting the affected part, and
keeping it below the level of the heart. Do NOT apply ice to a
snakebite; this will cause local vasoconstriction and may force the
venom deeper into the patient's circulation. If a constricting band is
applied, it should be proximal to the bite and should be tight enough
to slow venous return only, not cut off arterial supply.
Which of the following is a later sign of hepatitis?
• A:Fever and vomiting
• B:Jaundice
• C:Loss of appetite
• D:Fatigue -------------------------------------You selected B; This is correct!
Reason: Early signs and symptoms of viral hepatitis include loss of
appetite (anorexia), vomiting, fever, fatigue, and muscle and joint
pain. Jaundice (yellow sclera and skin) and right upper quadrant
,abdominal pain are not common early manifestations of hepatitis;
they usually develop within 1 to 2 weeks into the disease process.
A 60-year-old male complains of a tearing sensation in his abdomen. He
tells you the pain began suddenly and feels like someone is sticking a
knife into his abdomen. He is conscious and alert with a blood pressure
of 148/88 mm Hg, a pulse of 120 beats/min, and respirations of 22
breaths/min. In addition to administering high-flow oxygen, you should:
• A:perform a rapid head to toe assessment and prepare for transport.
• B:auscultate over his epigastrium to assess for bowel sounds.
• C:vigorously palpate his abdomen to assess for a pulsating mass.
• D:transport at once and be prepared to treat him for severe shock. ---
----------------------------------The correct answer is D;
Reason:Given the onset and nature of the patient's pain (eg, sudden
onset, tearing sensation), you should suspect that he has an acute
dissection of the abdominal aorta. Administer high-flow oxygen and
transport him at once. Acute aortic dissection can quickly cause an
aneurysm, which could rupture and cause profound shock. Therefore,
you must carefully monitor him and be prepared to treat him
accordingly. Unnecessary or vigorous palpation of his abdomen could
cause his aorta to rupture and should be avoided. A rapid head-to-toe
assessment is indicated for trauma patients with a significant
mechanism of injury and unresponsive medical patients; this patient
falls into neither of these categories. Auscultating bowel sounds in the
, field is time-consuming, will yield little information, and only delays
transport.
Which of the following statements regarding the function of insulin is
correct?
• A:It stimulates the liver to release glucose into the bloodstream.
• B:It facilitates the uptake of glucose from the bloodstream into the
cell.
• C:It causes the pancreas to produce glucose based on the body's
demand.
• D:It promotes the entry of glucose from the cell into the bloodstream.
-------------------------------------You selected B; This is correct!
Reason:Insulin is a hormone produced by the beta cells in the Islets of
Langerhans of the pancreas. It promotes the uptake of glucose from
the bloodstream into the cells where it is used in the production of
energy. Glucagon, a hormone produced by the alpha cells in the
pancreas, facilitates the conversion of glycogen to glucose
(glycogenolysis) in the liver. The liver does not produce glucose; it
produces glycogen, a complex sugar that the body cannot utilize until
it has been converted to glucose, a simple sugar.
A 72-year-old woman is found unresponsive in her poorly ventilated
home. Her skin is flushed, hot, and dry, and her respirations are rapid
