Theories of Health Behavior Change Questions
Question 1 of 5
Random sampling ensures that each subject has:
Correct Answer: B
Rationale: The correct answer is B: An equal chance of selection. Random sampling ensures that each subject in the population has an equal probability of being selected for the sample, which helps in reducing bias and obtaining a representative sample. This increases the generalizability of the findings to the entire population. A: Being selected systematically does not guarantee each subject an equal chance of selection. C: Being selected based on set criteria is not random and may introduce bias. D: Having characteristics that match other samples does not ensure equal chance of selection for each subject in the population.
Question 2 of 5
Nurse John is caring for a male client receiving lidocaine I.V. Which factor is the most relevant to administration of this medication?
Correct Answer: C
Rationale: The correct answer is C: Presence of premature ventricular contractions (PVCs) on a cardiac monitor. Lidocaine is commonly used to treat PVCs and ventricular arrhythmias. Monitoring for PVCs is crucial to assess the effectiveness of the medication. A decrease in arterial oxygen saturation (A) is not directly related to lidocaine administration. An increase in systemic blood pressure (B) is not a primary concern with lidocaine. Increase in intracranial pressure (ICP) (D) is not directly affected by lidocaine administration.
Question 3 of 5
George should be taught about testicular examinations during:
Correct Answer: D
Rationale: The correct answer is D because testicular examinations are most effective when started before age 20 to detect any abnormalities early. This is crucial for early detection of testicular cancer, which is more common in younger men. Teaching about testicular examinations after age 40 or after sexual activity starts is not ideal as it may delay the detection of potential issues. Waiting until after age 69 is too late for proactive prevention. Starting before age 20 ensures that individuals are informed and proactive about their testicular health from a young age.
Question 4 of 5
When performing oral care on a comatose client, Nurse Krina should:
Correct Answer: C
Rationale: Rationale for Choice C: 1. Placing the client in a side-lying position prevents aspiration. 2. Lowering the head of the bed helps with drainage and reduces the risk of choking. 3. This position also allows for better access to perform oral care safely. Summary of other choices: A. Applying lemon glycerin frequently can be drying and irritating to the lips. B. Brushing teeth with the client lying supine can increase the risk of aspiration. D. Cleaning the client's mouth with hydrogen peroxide can be harmful if ingested and is not recommended for routine oral care.
Question 5 of 5
Diagnostic assessment of Francis would probably not reveal:
Correct Answer: D
Rationale: The correct answer is D: Elevated thrombocyte counts. Diagnostic assessment of Francis, who likely has leukemia, would not reveal elevated thrombocyte counts because leukemia typically causes thrombocytopenia, not thrombocytosis. Thrombocytosis is an increased platelet count, which is not a common feature of leukemia. Predominance of lymphoblasts, leukocytosis, and abnormal blast cells in the bone marrow are all characteristic findings in leukemia.
