NUR 641E Midterm Exam Questions With Accurate Answers
100% Guarantee Pass 2026/2027
1. What is the primary function of Idarucizumab in relation to Dabigatran?
It is a type of anticoagulant.
It is used to treat respiratory conditions.
It is the antidote for Dabigatran.
It enhances the effects of Dabigatran.
2. Describe the significance of the activated partial thromboplastin time (aPTT)
in monitoring anticoagulant therapy.
The aPTT measures platelet function in the blood.
The aPTT is used to determine the dosage of antibiotics.
The aPTT indicates liver function status.
The aPTT is significant for monitoring anticoagulant therapy as it
helps assess the effectiveness of drugs that affect the intrinsic
pathway of coagulation.
3. Which condition is typically associated with caseous necrosis, and how does
the affected tissue appear?
Inflammatory reactions; accumulation of fibrin-like material
Acute pancreatitis; black and dead skin
Mycobacterial infections (e.g., tuberculosis); white to yellow cheese-
like appearance
Blood circulation problems; soft and friable tissue
,4. Describe the significance of maintaining calcium levels within the normal
range in the body.
Calcium is only important for blood clotting.
Calcium levels are not significant for bodily functions.
Calcium levels do not affect muscle function.
Maintaining calcium levels within the normal range is crucial for
bone health, muscle function, and nerve signaling.
5. Which antibiotic class is specifically known for its ability to disrupt bacterial
cell wall synthesis?
Penicillins
Aminoglycosides
Macrolides
Tetracyclines
6. If a patient has a deep vein thrombosis (DVT) in the leg, what complication
should healthcare providers monitor for?
Myocardial infarction
Chronic obstructive pulmonary disease
Stroke
Pulmonary embolism
7. A chest x-ray of a 67 y.o. patient demonstrates consolidation of a lower lobe
of the right lung. The patient also has high fever with chills, delirium, painful
cough with rusty-looking sputum, dyspnea, severe headache. The term
"consolidation" in this clinical situation describes:
, B. Ghon complex = tuberculosis granuloma, round calcified lesion
about 3-4 cm in diameter
A. Pulmonary consolidation = a large segment (ex. lobe) of lung is
filled with dense fluid (usually pus), which makes previously normal
radiolucent lung look like solid tissue
C. Neither a nor b choices are correct
8. Describe how the gastric pH affects the efficacy of orally administered drugs.
The gastric pH has no effect on drug absorption.
The gastric pH only affects liquid medications.
The gastric pH can inactivate some drugs, reducing their efficacy
when taken orally.
The gastric pH enhances the absorption of all drugs.
9. Describe how atrial natriuretic peptide contributes to the regulation of
plasma volume.
Atrial natriuretic peptide decreases blood flow to the kidneys.
Atrial natriuretic peptide has no role in plasma volume regulation.
Atrial natriuretic peptide contributes to the regulation of plasma
volume by promoting renal excretion of salt and water and causing
vasodilation.
Atrial natriuretic peptide increases plasma volume by retaining salt
and water.
10. Describe the significance of maintaining sodium levels within the normal
range in the human body.
Sodium levels primarily affect blood sugar levels.
, Maintaining sodium levels within the normal range is crucial for
fluid balance, nerve function, and muscle contraction.
Sodium levels are not significant for bodily functions.
Sodium is only important for digestive processes.
11. Describe the physiological mechanism behind the changes in pulse
amplitude observed in pulsus paradoxus.
During expiration, intrathoracic pressure increases, causing stronger
pulse amplitude.
Pulsus paradoxus is caused by increased heart rate during inspiration.
During inspiration, intrathoracic pressure decreases, leading to
reduced venous return and weaker pulse amplitude.
Pulsus paradoxus results from a constant blood pressure change
during respiration.
12. What is the correct definition of bioavailability?
The theoretical volume that would be necessary to contain the total
amount of administered drug at the same concentration observed in
blood plasma.
The fraction of the administered drug that reaches the general
circulation.
The phenomenon in which a drug gets metabolized at a specific
location in the body that reduces the concentration of the drug
reaching systemic circulation.
The phenomenon in which proteins in blood bind to drugs and affect
drug distribution.
13. What does the acronym ADME stand for in pharmacokinetics?
