1. What are the signs and symptoms of a potential infection?

A. Fever, chills, and increased heart rate
B. Increased white blood cell count and fever
C. Shortness of breath and confusion
D. Sweating and low blood pressure

Correct answer: A

Rationale: The correct answer is A: Fever, chills, and increased heart rate are classic signs of an infection. These symptoms indicate the body's response to an invading pathogen. Choice B, 'Increased white blood cell count and fever,' is not a primary symptom that a person would typically notice themselves, and white blood cell count needs to be tested. Choice C, 'Shortness of breath and confusion,' may indicate other conditions like heart or lung issues rather than a general infection. Choice D, 'Sweating and low blood pressure,' are not specific to infections and can be caused by various factors like heat or dehydration.

2. Which of the following interventions should the nurse implement for a client with dementia who is at risk of falling?

A. Keep the bed in the lowest position
B. Raise all four side rails to prevent falls
C. Assist with ambulation every 2 hours
D. Use a bed exit alarm to notify staff of attempts to leave the bed

Correct answer: D

Rationale: The correct intervention for a client with dementia at risk of falling is to use a bed exit alarm to notify staff of attempts to leave the bed. This intervention helps in preventing falls by alerting the staff when the client tries to get out of bed. Keeping the bed in the lowest position (Choice A) may not prevent falls and could make it challenging for staff to provide care. Raising all four side rails (Choice B) can be a restraint and is not recommended as it may lead to entrapment or other risks. Assisting with ambulation every 2 hours (Choice C) may not be feasible or effective in preventing falls, as the client may attempt to get out of bed at any time.

3. What is the proper technique for measuring a patient's blood pressure?

A. Place the cuff at heart level and listen for Korotkoff sounds
B. Ensure the patient is in a seated position and inflate the cuff to 180 mmHg
C. Use a manual sphygmomanometer and measure blood pressure on both arms
D. Monitor pulse rate and apply pressure to the brachial artery

Correct answer: A

Rationale: The correct technique for measuring blood pressure involves placing the cuff at heart level to ensure accurate readings. Listening for Korotkoff sounds helps determine the systolic and diastolic pressures. Choice B is incorrect as inflating the cuff to 180 mmHg is excessive and can lead to inaccurate readings. Choice C is incorrect as it is unnecessary to measure blood pressure on both arms unless there is a specific medical reason to do so. Choice D is incorrect as monitoring pulse rate and applying pressure to the brachial artery are not part of the standard blood pressure measurement technique.

4. 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.

5. What is the role of the nurse in postoperative care for a patient with a hip replacement?

A. Monitor for signs of infection and administer pain relief
B. Ensure the patient follows a low-calcium diet
C. Ensure the patient uses crutches to avoid pressure on the hip
D. Monitor for signs of deep vein thrombosis

Correct answer: A

Rationale: The correct answer is A: Monitor for signs of infection and administer pain relief. In postoperative care for a patient with a hip replacement, it is crucial for the nurse to monitor for signs of infection, such as increased pain, redness, swelling, or drainage from the surgical site. Administering pain relief is also important to ensure the patient's comfort and aid in their recovery. Choices B, C, and D are incorrect as they do not directly relate to the immediate postoperative care needs of a patient with a hip replacement. Ensuring a low-calcium diet, using crutches, or monitoring for deep vein thrombosis are not primary responsibilities in the immediate postoperative period for this type of surgery.
