What occurs when a drug binds to a receptor in the body?

• It alters the receptor to become nonresponsive to its usual

endogenous molecules.

• It increases or decreases the activity of that receptor.
• It gives the receptor a new function.
• It prevents the action of the receptor by altering its response

to chemical mediators. - ANSWER-b.

A patient is receiving intravenous gentamicin. A serum drug test reveals toxic levels. The dosing is correct, and this medication has been tolerated by this patient in the past. Which could be a probable cause of the test result?

• A loading dose was not given. 1 / 4

• | P a g e

• The drug was not completely dissolved in the IV solution.
• The patient is taking another medication that binds to serum

albumin.

• The medication is being given at a frequency that is longer

than its half-life. - ANSWER-c.

A patient reports becoming "immune" to a medication because it no longer works to alleviate symptoms. The nurse recognizes

that this decreased effectiveness is likely caused by:

• antagonists produced by the body that compete with the drug

for receptor sites.

• decreased selectivity of receptor sites, resulting in a variety of

effects.

• desensitization of receptor sites by continual exposure to the

drug.

• synthesis of more receptor sites in response to the medication.
• ANSWER-c.

• It binds to different types of receptors in the body. 2 / 4

• | P a g e

• It can cause constipation in toxic doses.
• It causes only one type of response, and the constipation is

coincidental.

• It is selective to receptors that regulate more than one body

process. - ANSWER-d.

The nurse is administering morning medications. The nurse gives a patient multiple medications, two of which compete for plasma albumin receptor sites. As a result of this concurrent administration, the nurse can anticipate that what might occur?Select all that apply.

• Binding of one or both agents will be reduced.
• Plasma levels of free drug will rise.
• Plasma levels of free drug will fall.
• The increase in free drug will intensify effects.
• The increase in bound drug will intensify effects. - ANSWER-

a.b.d.

When administering medications to infants, it is important to remember which of the following? 3 / 4

• | P a g e

Select all that apply.

• Breast-feeding infants are more likely to develop toxicity

when given lipid-soluble drugs.

• Immaturity of renal function in infancy causes infants to

excrete drugs less efficiently.

• Infants have immature livers, which slows drug metabolism.
• Infants are more sensitive to medications that act on the

central nervous system (CNS).

• Oral medications are contraindicated in infants, because PO

administration requires a cooperative patient. - ANSWER-b.c.d.

A nursing student is preparing to give a medication that has a boxed warning. The student asks the nurse what this means.What will the nurse explain about boxed warnings?
