1. Which lab value is critical for monitoring warfarin therapy?

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

2. A nurse is caring for a client with schizophrenia. Which of the following assessment findings should the nurse expect?

Correct answer: B

Rationale: In schizophrenia, clients often display an inability to identify common objects due to cognitive impairment. This is known as associative agnosia, where individuals struggle to recognize familiar objects, faces, or sounds. Choices A, C, and D are not typically associated with schizophrenia. Decreased level of consciousness is more indicative of conditions like head trauma or drug overdose. Poor problem-solving ability may be seen in various mental health disorders but is not specific to schizophrenia. Preoccupation with somatic disturbances is more commonly seen in somatic symptom disorders or somatic delusions, not a typical finding in schizophrenia.

3. A client with diabetes mellitus is being taught by a nurse on managing hypoglycemia. Which of the following instructions should the nurse include?

Correct answer: B

Rationale: The correct answer is B: Consume 15 grams of a fast-acting carbohydrate. Consuming 15 grams of a fast-acting carbohydrate, such as glucose tablets or juice, helps raise blood glucose levels quickly in cases of hypoglycemia. Choice A is incorrect because avoiding carbohydrate-rich foods during hypoglycemia can worsen the condition. Choice C is incorrect as drinking water does not effectively raise blood glucose levels. Choice D is incorrect as eating a snack before exercising is more related to preventing exercise-induced hypoglycemia, not managing hypoglycemia.

4. A nurse is reviewing the laboratory values of a client who is taking spironolactone. Which of the following values should the nurse report to the provider?

Correct answer: B

Rationale: The correct answer is B: 'Potassium 5.2 mEq/L.' When a client is taking spironolactone, which is a potassium-sparing diuretic, monitoring potassium levels is crucial. A potassium level of 5.2 mEq/L is higher than normal and can lead to cardiac dysrhythmias, so it should be reported. Choices A, C, and D are within normal ranges and would not be of immediate concern when assessing a client taking spironolactone.

5. How should a healthcare professional assess a patient's pain level post-surgery?

Correct answer: A

Rationale: Corrected Rationale: Using a pain rating scale is the most appropriate method to assess a patient's pain level post-surgery. Pain rating scales provide a standardized way for patients to communicate their pain intensity, allowing for accurate assessment and effective pain management. Checking vital signs (choice B) is important for monitoring a patient's overall health status but may not directly reflect their pain level. Observing for non-verbal cues (choice C) is valuable, but it may not always provide a clear indication of the pain intensity. Checking for abnormal breath sounds (choice D) is relevant for assessing respiratory status but does not directly evaluate the patient's pain level.
