Question 1 of 5
The healthcare provider is teaching a patient about contact lens care. Which instructions will the healthcare provider include in the teaching session?
Correct Answer: B
Rationale: The correct answer is B. Washing and rinsing the lens storage case daily is essential to prevent contamination and infections. Choice A is incorrect as tap water should not be used to clean soft lenses due to the risk of introducing harmful microorganisms. Choice C is incorrect as the storage solution should not be reused for longer than recommended to maintain its effectiveness and prevent eye infections. Choice D is incorrect because lenses should be stored in a clean, disinfected case, not just in a cool, dry place, to avoid contamination.
Question 2 of 5
When planning care for a newly admitted elderly client who is severely dehydrated, which task is appropriate to assign to an unlicensed assistive personnel (UAP)?
Correct Answer: B
Rationale: The correct answer is B. Assigning the UAP to report hourly outputs of less than 30 ml/hr is appropriate as it falls within their scope of practice and does not involve making clinical assessments or decisions. Choices A, C, and D involve tasks that require a higher level of clinical judgment and training. Choice A requires assessing mucous membranes, which is beyond the UAP's scope. Choice C involves assessing movement ability, which requires more specialized training. Choice D involves assessing skin turgor, which also requires a higher level of clinical judgment.
Question 3 of 5
Which serum blood finding in diabetic ketoacidosis alerts the nurse that immediate action is required?
Correct Answer: C
Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.
Question 4 of 5
When caring for a client receiving warfarin sodium (Coumadin), which lab test would the nurse monitor to determine therapeutic response to the drug?
Correct Answer: C
Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.
Question 5 of 5
A client is admitted to the emergency room following an acute asthma attack. Which of the following assessments would be expected by the nurse?
Correct Answer: A
Rationale: During an acute asthma attack, one of the expected assessments by the nurse would be diffuse expiratory wheezing. This occurs due to narrowed airways and increased airflow velocity. Choice B, a loose productive cough, is not typically associated with an asthma attack. Choice C, no relief from inhaler, may indicate ineffective treatment but is not a direct assessment finding related to the physical examination. Choice D, fever and chills, are not typical symptoms of an asthma attack and would not be expected findings during the initial assessment of an acute asthma attack.
