Theories of Health Behavior Change Questions
Question 1 of 5
As a nurse, you are always alerted to monitor status asthmaticus who will likely and initially manifest symptoms of:
Correct Answer: C
Rationale: The correct answer is C: respiratory alkalosis. In status asthmaticus, the patient experiences prolonged, severe asthma attacks leading to hyperventilation. Hyperventilation causes excessive removal of carbon dioxide, leading to a decrease in PaCO2 levels and respiratory alkalosis. The other choices are incorrect because metabolic alkalosis (choice A) is not typically associated with asthma attacks, respiratory acidosis (choice B) occurs with inadequate ventilation, and metabolic acidosis (choice D) is not a common initial manifestation of status asthmaticus.
Question 2 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 3 of 5
A male client was on warfarin (Coumadin) before admission, and has been receiving heparin I.V. for 2 days. The partial thromboplastin time (PTT) is 68 seconds. What should Nurse Carla do?
Correct Answer: A
Rationale: The correct answer is A: Stop the I.V. infusion of heparin and notify the physician. Heparin is an anticoagulant that prolongs the PTT. A PTT of 68 seconds indicates that the client may be at risk for bleeding due to excessive anticoagulation. Stopping the heparin infusion is crucial to prevent further complications. Notifying the physician is essential for further management. B: Continuing treatment as ordered would pose a risk of potential bleeding complications due to excessive anticoagulation. C: Warfarin affects the INR, not the PTT. Expecting warfarin to increase the PTT is incorrect. D: Increasing the dosage of heparin is contraindicated as the PTT is already elevated, indicating a risk of bleeding.
Question 4 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 5 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.
