1. How should a healthcare professional respond to a patient with hypokalemia?

• A. Administer potassium supplements and monitor ECG
• B. Restrict fluid intake and provide a high-sodium diet
• C. Monitor sodium levels and provide insulin therapy
• D. Provide calcium supplements and monitor for hyperkalemia

Correct answer: A

Rationale: Hypokalemia is managed by administering potassium supplements to correct the low potassium levels in the body. Monitoring the ECG is essential because low potassium levels can lead to cardiac arrhythmias. Choice B is incorrect as restricting fluid intake and providing a high-sodium diet are not appropriate for managing hypokalemia. Choice C is incorrect because hypokalemia involves low potassium levels, not sodium levels, and insulin therapy does not directly address this issue. Choice D is incorrect as calcium supplements are not indicated for hypokalemia, and monitoring for hyperkalemia is not relevant in this case.

2. When collecting data from a client with posttraumatic stress disorder (PTSD), which of the following manifestations should the nurse expect?

• A. Amnesia
• B. Hypervigilance
• C. Hallucinations
• D. Severe agitation

Correct answer: B

Rationale: The correct manifestation to expect when collecting data from a client with PTSD is hypervigilance. Hypervigilance refers to increased alertness, which is a common symptom of PTSD. This heightened state of awareness is characterized by an exaggerated startle response, being easily startled, and constantly scanning the environment for potential threats. Amnesia (choice A) is not typically a primary manifestation of PTSD; it is more commonly associated with dissociative disorders. Hallucinations (choice C) involve perceiving things that are not present and are not typically a hallmark symptom of PTSD. Severe agitation (choice D) may occur in individuals with PTSD, but hypervigilance is a more specific and common manifestation associated with this disorder.

3. A nurse is caring for a client who has bipolar disorder and is experiencing acute mania. The nurse obtained a verbal prescription for restraints. Which of the following actions should the nurse take?

• A. Request a renewal of the prescription every 8 hours.
• B. Check the client's peripheral pulse rate every 30 minutes.
• C. Obtain a prescription for restraint within 4 hours.
• D. Document the client's condition every 15 minutes.

Correct answer: D

Rationale: In a situation where a verbal prescription for restraints is obtained for a client experiencing acute mania, the nurse should document the client's condition every 15 minutes. This frequent documentation allows for accurate monitoring of the client's condition, ensuring safety and compliance. Requesting a renewal of the prescription every 8 hours (Choice A) is not necessary as the focus should be on monitoring the client's condition. Checking the client's peripheral pulse rate every 30 minutes (Choice B) is not directly related to the need for restraints in this scenario. Obtaining a prescription for restraint within 4 hours (Choice C) is not a priority when a verbal prescription is already obtained and immediate action is needed for the client's safety.

4. Which of the following findings indicates a need for immediate attention in a client diagnosed with delirium?

• A. Confusion and disorientation that resolve with rest
• B. A blood pressure reading of 110/70
• C. Irritability and agitation that worsen throughout the day
• D. Mild confusion during the evening hours

Correct answer: C

Rationale: The correct answer is C: Irritability and agitation that worsen throughout the day. These symptoms are concerning in a client diagnosed with delirium as they may indicate an exacerbation of the condition or an underlying cause that requires immediate attention. Option A describes symptoms that resolve with rest, which may not be as urgent. Option B provides a normal blood pressure reading, which is not typically associated with immediate attention in delirium cases. Option D describes mild confusion during specific hours, which may not be as critical as worsening symptoms throughout the day.

5. What are the key differences between viral and bacterial infections?

• A. Viral infections typically last longer than bacterial infections.
• B. Bacterial infections typically cause high fever.
• C. Both bacterial and viral infections cause rashes.
• D. Viral infections cause sudden onset of symptoms.

Correct answer: A

Rationale: The correct answer is A. Viral infections typically last longer than bacterial infections. This is because viral infections often require the body's immune system to fight off the virus, leading to a longer duration of illness. Bacterial infections, on the other hand, often cause a rapid onset of symptoms due to the toxins produced by bacteria. Choice B is incorrect because not all bacterial infections cause high fever. Choice C is incorrect because rashes can be caused by both bacterial and viral infections, but not always. Choice D is incorrect because while some viral infections may cause a sudden onset of symptoms, it is not a key distinguishing factor between viral and bacterial infections.
