VERSION A
When administering the drug senna to a patient, a healthcare provider must inform the patient of which of
the following?
A. This drug is intended to lower blood pressure and is best used in combination with other antihypertensives.
B. This drug is not intended for long-term use.
C. The patient must limit his/her fiber intake.
D. Advise patient to change positions slowly to limit the risk of orthostatic hypotension.
Correct Answer: B. This drug is not intended for long-term use.
Rationale
Senna is a stimulant laxative intended for short-term use to relieve constipation. Prolonged use can lead to
dependence, electrolyte imbalances, and decreased bowel function. Long-term use is not recommended
without provider supervision.

When giving digoxin (Lanoxin) to a patient, the health care provider notices various signs and symptoms of
an overdose. The health care provider knows to give which of the following to reverse digoxin toxicity?
A. Naloxone
B. Vitamin K
C. Digibind
D. Flumazenil
Correct Answer: C. Digibind.
Rationale
Digibind (digoxin immune Fab) is the specific antidote for digoxin toxicity. It binds to digoxin molecules,
preventing them from exerting their effects on the heart. Naloxone is for opioid overdose, Vitamin K is for
warfarin, and Flumazenil is for benzodiazepines.

While providing an Angiotensin-converting enzyme (ACE) inhibitor, the patient asks what the action of the
drug is. As a healthcare provider, you explain that the action of an ACE inhibitor is:
A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor angiotensin II.
B. To inhibit reabsorption of sodium back into the body, ultimately increasing urine output and lowering blood
pressure.
C. To decrease heart rate and blood pressure by competing with Beta1 and Beta2 receptors in the heart and
,lungs.
D. To lower blood glucose by stimulating the release of insulin.
Correct Answer: A. To lower blood pressure by blocking the conversion of angiotensin I to vasoconstrictor
angiotensin II.
Rationale
ACE inhibitors block the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor, which results in
vasodilation and decreased blood pressure. This action also reduces aldosterone secretion, decreasing sodium
and water retention.

Which of the following types of insulin is "long-acting"?
A. Lispro (Humalog)
B. NPH (Humulin N)
C. Regular insulin (Humulin R)
D. Glargine (Lantus)
Correct Answer: D. Glargine (Lantus).
Rationale
Glargine is a long-acting insulin with a duration of action up to 24 hours. Lispro is rapid-acting, NPH is
intermediate-acting, and Regular insulin is short-acting.

What is the therapeutic use of metformin?
A. Lower blood pressure.
B. To diminish seizure activity.
C. The maintenance of a person's blood glucose.
D. Increase heart rate and decrease gastrointestinal secretions.
Correct Answer: C. The maintenance of a person's blood glucose.
Rationale
Metformin is an antidiabetic medication used to lower blood glucose levels in clients with type 2 diabetes
mellitus. It works by decreasing hepatic glucose production, decreasing intestinal glucose absorption, and
increasing insulin sensitivity.

What is the correct definition for absorption of a drug?
A. Movement of drug from site of administration to various tissues of the body.
B. Describes the absorption, distribution, metabolism, and excretion of drugs.
C. These types of drugs can be taken over the counter.
D. This addresses how various drugs affect different forms of the body.
,Correct Answer: A. Movement of drug from site of administration to various tissues of the body.
Rationale
Absorption is the process by which a drug moves from its site of administration into the bloodstream. Option
B describes pharmacokinetics, Option C refers to over-the-counter drugs, and Option D describes
pharmacodynamics.

What do you assess for in a patient who is on Valproate? Select all that apply.
A. Suicidal thoughts
B. Monitor for seizures
C. Bipolar disorder
D. Migraines
Correct Answer: A, B
Rationale
Valproate is an anticonvulsant and mood stabilizer. Clients should be monitored for suicidal thoughts (black box
warning), and the medication is used to monitor for seizure activity. Bipolar disorder and migraines are
indications for use, not assessments.

What is true about food and drug precautions? Select all that apply.
A. You must limit certain types of food or concurrent administration of certain types of drugs.
B. Certain combinations of food and drugs can cause adverse reactions.
C. Precautions may require limiting certain types of food or concurring drugs rather than restricting the drug
itself.
D. When one drug changes the way, another drug affects that drug.
Correct Answer: A, B, C
Rationale
Food and drug interactions can cause adverse reactions. Precautions may involve limiting certain foods or other
drugs. Option D describes drug-drug interactions, which are different from food-drug interactions.

ACE Inhibitors are used in the treatment of all EXCEPT:
A. Hypertension
B. Heart Failure
C. Hypotension
D. Diabetic nephropathy
Correct Answer: C. Hypotension.
, Rationale
ACE inhibitors lower blood pressure and are used to treat hypertension, heart failure, and diabetic
nephropathy. They are contraindicated in hypotension as they would further decrease blood pressure.

Which of the following is used to treat migraine headaches?
A. Beta-blockers
B. Cholinesterase Inhibitors
C. ACE inhibitors
D. Anti-epileptic drugs (AEDs)
Correct Answer: D. Anti-epileptic drugs (AEDs).
Rationale
Some anti-epileptic drugs (AEDs) such as valproate and topiramate are used for migraine prophylaxis. Beta-
blockers are also used for migraine prevention, but AEDs are the correct answer in this context.

When administering a Serotonin Antagonist it is important to monitor for:
A. Intake and output
B. Mental status changes
C. Respiratory rate
D. Anorexia
Correct Answer: B. Mental status changes.
Rationale
Serotonin antagonists, such as ondansetron, can cause central nervous system effects including headache,
dizziness, and mental status changes. Monitoring mental status is important for early detection of adverse
effects.

Which of the following is the antidote for Heparin?
A. Protamine sulfate
B. Vitamin K
C. Naloxone
D. Toradol
Correct Answer: A. Protamine sulfate.
Rationale
Protamine sulfate is the specific antidote for heparin. It binds to heparin to form a stable complex, neutralizing
its anticoagulant effects. Vitamin K is the antidote for warfarin, Naloxone is for opioids, and Toradol is an NSAID.
