Back.0}ound: Clinical reasoning.is a critical cog.itive sk.ll that enables underg.aduate nursing.students to mak. clinically sound decisions. A lapse in clinical reasoning.can result in unintended harm to patients. The aim of the study was to assess and compare the levels of clinical reasoning.sk.lls between third year and fourth year underg.aduate nursing.students. Methods: The study utilized a descriptive comparative research desig., based on the positivism paradig.. 410 underg.aduate nursing.students were systematically sampled and recruited into the study. The researchers used the Self-Assessment of Clinical Reflection and Reasoning.questionnaire to collect data on clinical reasoning.sk.lls from third- and fourth-year nursing.students while adhering.to ethical principles of human dig.ity. Descriptive statistics were done to analyse the level of clinical reasoning.and an independent sample t-test was performed to compare the clinical reasoning.sk.lls of the student. A p value of 0.05 was accepted. Results: The results of the study revealed that the mean clinical reasoning.scores of the underg.aduate nursing.students were k.owledg./theory application (M = 3.84;SD = 1.04);decision-mak.ng.based on experience and evidence (M = 4.09;SD = 1.01);dealing.with uncertainty (M = 3.93;SD = 0.87);reflection and reasoning.(M = 3.77;SD = 3.88). The mean difference in clinical reasoning.sk.lls between third- and fourth-year underg.aduate nursing.students was not sig.ificantly different from an independent sample t-test scores (t = −1.08;p = 0.28);(t = −0.29;p = 0.73);(t = 1.19;p = 0.24);(t = −0.57;p = 0.57). Since the p-value is >0.05, the null hypothesis (H0) “there is no sig.ificantno sig.ificant difference in clinical reasoning.between third year and fourth year underg.aduate nursing.students”, was accepted. Conclusion: This study has shown that the level of clinical reasoning.sk.lls of the underg.aduate nursing.students was moderate to low. This meant that the teaching.method

Quantum mechanics imposes limits on measurement accuracy throug. quantum noise which typically has two components: First is the shot noise orig.nating.from vacuum fluctuations and referred to as the imprecision noise. Second is the quantum back.ction orig.nating.from the “action” of the measurement back.on the object being.measured.
