A nurse is preparing to administer digoxin 5 mg PO to a client. The amount available is digoxin 0.5 mg/tablet. How many tablets should the nurse administer? (Round the answer to the nearest whole number, Use leading zero if it applies. Do not use a trailing zero.)

A) Researcher:
The nurse is gathering evidence-based practice (EBP) on catheter-associated urinary tract infections (CAUTI), which involves systematically collecting, analyzing, and reviewing existing studies or guidelines to inform clinical practice. This is the role of the researcher in EBP. Nurses in this role contribute to improving patient outcomes by identifying best practices, assessing existing evidence, and implementing findings to reduce complications, such as CAUTIs.

B) Nurse manager:
While a nurse manager may oversee quality improvement projects, staffing, and other operational aspects of nursing care, they are not typically the ones actively gathering evidence-based data themselves. Nurse managers may utilize the findings from research but are not directly involved in the research process unless leading specific studies.
C) Case manager:
A case manager primarily coordinates care for individual patients, ensuring they receive the appropriate resources and follow-up care. They help manage the continuity of care across different settings but do not focus on gathering or researching evidence for clinical practices. Their role is more focused on patient outcomes and care delivery rather than generating evidence.

D) Educator:
While an educator might be involved in teaching staff or patients about preventing CAUTI, the role described in the question specifically refers to gathering evidence-based practice information. Educators may use research findings in their teaching, but gathering evidence is a distinct activity that fits the role of the researcher in EBP.

A) Decreased peripheral pulses:
Increased body temperature typically causes vasodilation rather than vasoconstriction, leading to improved blood flow rather than decreased. As a result, peripheral pulses are more likely to be normal or even increased in response to fever. Decreased peripheral pulses would be more indicative of conditions like shock or hypoperfusion, not fever.

B) Heart rate 108/min:
Fever causes an increase in metabolic demand, which often results in a compensatory increase in heart rate (tachycardia). This phenomenon, known as "fever tachycardia," occurs as the body attempts to circulate blood more rapidly to meet the increased oxygen and nutrient demands caused by elevated body temperature. A heart rate of 108 beats per minute is a normal response to fever, particularly when the temperature reaches 39°C (102.27°F).
C) Respiratory rate 10 breaths/min:
A respiratory rate of 10 breaths per minute is considered bradypnea (abnormally slow breathing), which is typically not associated with fever. Fever usually leads to an increase in respiratory rate (tachypnea) as the body attempts to cool itself through increased evaporation of sweat and breathing. A respiratory rate of 10 breaths/min is more likely to be seen in conditions like drug overdose, head injury, or respiratory depression, rather than fever.
D) Dilated pupils:
Dilated pupils (mydriasis) are typically associated with sympathetic nervous system activation, which can be caused by certain drugs, trauma, or neurological conditions. Fever, however, generally causes only mild changes in pupil size and is more likely to lead to constricted pupils (miosis) in response to certain stress hormones. Dilated pupils are not a typical finding with fever.
