Which of the following would provide the weakest
evidence for practice?
A.
Case study
B.
Case-control study
C.
Quasi-experimental study - Answer>> A.
Level Evidence type I meta-analysis and/or systematic
review of randomized-controlled trials (RCT); II single
RCT; III quasi-experiment (non-randomized); IV non-
experimental study (case-control, cohort, correlational);
V systematic reviews of descriptive studies or
qualitative studies; VI single qualitative study or cross-
section study (survey); VII expert opinion, case reports,

serum K + rises, presenting with
varying levels of peaked T waves
(secondary to increased repolarization of the cardiac
tissue), flattened P waves, and increased PR intervals
(secondary to suppression of atrial conductivity). These
changes are followed by widening and slurring of the
QRS complex (secondary to delay in ventricular
conduction as well as delays in myocardial conduction)
with eventual development of supraventricular
tachycardia, ventricular tachycardia, bradycardia, or
ventricular fibrillation (Doherty, 2017, p. 308).
The Henderson-Hasselebalch equation is a negative
logarithm that calculates the level of
A.
Bicarbonate ions
B.
Dioxide ions
C.
Hydrogen ions - Answer>> C.
The Henderson-Hasselebalch equation calculates
plasma pH. The pH is a negative logarithm that
measures the level of hydrogen ions (H+), which means
that there is an inverse relationship between the pH
and H+. The pH decreases with a rise in H+ and
increases with a fall in H+. The pH remains normal
when there is a balance in changes of carbon dioxide
(CO2) and bicarbonate (HCO3) (Barry, Deacon,
Hernandez, & Jones, 2016, p. 145).
The neonatal nurse practitioner (NNP) knows that a
serum peak level of a drug is generally reflective of the
infants:
A.
Excretion of metabolites
B.

Digestion of the drug
C.
Volume of distribution
answer - Answer>> C.
Volume of distribution (Vd) is influenced by gestational
age due to the rapid changes in total body water and
fluid shifts (Allegaert et al., 2018, p. 428; Wade, 2015,
p. 666).
Infants with large extracellular fluid volumes have
increased Vd for water-soluble drugs and may reduce
peak drug values and affect drug excretion (Blackburn,
2018, p. 198).
Decreased body fat in preterm and intrauterine growth-
restricted infants decreases the Vd for lipophilic drugs
(Blackburn, 2018, p. 199).
Pharmacokinetics is the process of drug
A.
Absorption, distribution, biotransformation, and
excretion
B.
Adaptations made to physiological systems by the
drugs
C.
Alterations, metabolism, and excretion in the cellular
matrix - Answer>> A.
Pharmacokinetics are the mathematical relationships
between drug dose and blood levels over time.
Pharmacokinetic processes include absorption,
distribution, metabolism (biotransformation), and
excretion (Allegaert et al., 2018, pp. 419-421;
Blackburn, 2018; pp. 180-181; Wade, 2015, p. 665).
Phase I drug metabolism reactions are mediated by
A.
