ATI PHARMACOLOGYFINAL EXAM REVIEW.
1.A nurse is preparing to administer a dose of lactulose to a client who has cirrhosis.
The client states, "I don't need this medication. I am not constipated." The nurse
should explain that in clients who have cirrhosis, lactulose is used to decrease levels
of which of the following components in the bloodstream?
a. Glucose
b. Ammonia
c. Potassium
d. Bicarbonate
Rationale:
Lactulose, a disaccharide, is a sugar that works as an osmotic diuretic. It prevents
absorption of ammonia in the colon. Accumulation of ammonia in the bloodstream,
which occurs in pathologic conditions of the liver, such as cirrhosis, may affect the
central nervous system, causing hepatic encephalopathy or coma.
2. A nurse on a medical unit is planning care for an older adult client who takes
several medications. Which of the following prescribed medications places the
client at risk for orthostatic hypotension? (Select all that apply.)
a. Furosemide
b. Telmisartan
c. Duloxetine
d. Clopidogrel
, e. Atorvastatin
3. A nurse is caring for a client who has difficulty swallowing medications and is
prescribed enteric-coated aspirin PO once daily. The client asks if the medication
can be crushed to make it easier to swallow. Which of the following responses
should the nurse provide?
a. "Crushing the medication might cause you to have a stomach-ache or
indigestion
b. "Crushing the medication is a good idea, and I can mix it in some ice
cream for you.”
c. "Crushing the medication would release all the medication at once, rather
than over time."
d. "Crushing is unsafe, as it destroys the ingredients in the medication."
Rationale:
The pill is enteric-coated to prevent breakdown in the stomach
and decrease the possibility of GI distress. Crushing destroys protection.
4. A nurse is providing teaching for a client who is newly diagnosed with type 2
diabetes mellitus and has a prescription for glipizide. Which of the following
statements by the nurse best describes the action of glipizide?
a. "Glipizide absorbs the excess carbohydrates in your system."
b. "Glipizide stimulates your pancreas to release insulin."
c. "Glipizide replaces insulin that is not being produced by your
pancreas."
d. "Glipizide prevents your liver from destroying your insulin."
Rationale:
Glipizide is an oral antidiabetic medication in the pharmacological classification of
sulfonylurea agents. These medications help to lower blood glucose levels in clients
who have type 2 diabetes mellitus using several methods, including reducing
, glucose output by the liver, increasing peripheral sensitivity to insulin, and
stimulating the release of insulin from the functioning beta cells of the pancreas.

to be started on intravenous revamping therapy. The nurse should instruct the
client that this medication can cause which of the following adverse effects?
a. Constipation
b. Black coloured stools
c. Staining of teeth
d. Body secretions turning a red-orange colour
Rationale:

6. A nurse is caring for a client who has congestive heart failure and is taking
digoxin daily. The client refused breakfast and is complaining of nausea and
weakness. Which of the following actions should the nurse take first?
a. A. Check the client's vital signs.
b. Request a dietitian consult.
c. Suggest that the client rests before eating the meal.
d. Request an order for an antiemetic.
Rationale:
It is possible that the client's nausea is secondary to digoxin toxicity. Assess
for bradycardia, a symptom of digoxin toxicity. The nurse should withhold the
medication and call the provider if the client's heart rate is less than 60 bpm.
