Lehne's Pharmacology for Nursing Care10TH EDITION Chapter 2 questions with
answers
Evolution of Nursing Responsibilities Regarding Drugs - ANSWER: ➡ give the right drug to
the right patient in the right dose by the right route at the right time, right assessment, right
documentation, right evaluation, the patient's rights to education, and the patient's right of
refusal
(Application of Pharmacology in Patient Care) - ANSWER: ➡ eight aspects of drug therapy:
(1) preadministration assessment, (2) dosage and administration, (3) promoting
therapeutic effects, (4) minimizing adverse effects, (5) minimizing adverse interactions, (6)
making "as needed" (PRN) decisions, (7) evaluating responses to medication, and (8)
managing toxicity.
Preadministration Assessment (Application of Pharmacology in Patient Care) - ANSWER:
➡ (1) collecting baseline data needed to evaluate therapeutic and adverse (i.e., undesired)
responses, (2) identifying high-risk patients, and (3) assessing the patient's capacity for
self-care.
Collecting Baseline Data (Preadministration Assessment) - ANSWER: ➡ Baseline data are
needed to evaluate both therapeutic and adverse drug responses. Without these data, we
would have no way of determining the effectiveness of our drug.
Identifying High-Risk Patients (Preadministration Assessment) - ANSWER: ➡ Multiple
factors can predispose an individual to adverse reactions from specific drugs. Important
predisposing factors are pathophysiology (especially liver and kidney impairment), genetic
factors, drug allergies, and life span considerations such as pregnancy or very young or
advanced age.
Dosage and Administration (Application of Pharmacology in Patient Care) - ANSWER: ➡ •
Read the medication order carefully. If the order is unclear, verify it with the prescriber.
, • Verify the identity of the patient by comparing the name on the wristband with the name
on the drug order or medication administration record.
• Read the medication label carefully. Verify the identity of the drug, the amount of drug
(per tablet, volume of liquid, etc.), and its suitability for administration by the intended
route.
• Verify dosage calculations.
• Implement any special handling the drug may require.
• Don't administer any drug if you don't understand the reason for its use.
Promoting Therapeutic Effects (Application of Pharmacology in Patient Care) - ANSWER:
➡ Drug therapy can often be enhanced by nonpharmacologic measures. Examples include
(1) enhancing drug therapy of asthma through breathing exercises, biofeedback, and
emotional support; (2) enhancing drug therapy of arthritis through exercise, physical
therapy, and rest; and (3) enhancing drug therapy of hypertension through weight
reduction, smoking cessation, and sodium restriction.
Minimizing Adverse Effects (Application of Pharmacology in Patient Care) - ANSWER: ➡
Measures to reduce adverse events include identifying high-risk patients, ensuring proper
administration, and teaching patients to avoid activities that might precipitate an adverse
event.
To help reduce adverse effects, you must know the following about the drugs you
administer: (Minimizing Adverse Effects) - ANSWER: ➡ • The major adverse effects the
drug can produce
• When these reactions are likely to occur
• Early signs that an adverse reaction is developing
• Interventions that can minimize discomfort and harm
Making PRN Decisions (Application of Pharmacology in Patient Care) - ANSWER: ➡ PRN
stands for pro re nata, a Latin phrase meaning as needed. A PRN medication order is one in
which the nurse has discretion regarding when to give a drug and, in some situations, how
much drug to give.
