1. What are the key signs of hyperkalemia and how should it be treated?

A. Elevated potassium levels, muscle weakness; administer calcium gluconate
B. Decreased potassium levels, confusion; administer potassium chloride
C. Elevated sodium levels, bradycardia; administer sodium bicarbonate
D. Low sodium levels, muscle cramps; administer sodium chloride

Correct answer: A

Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.

2. What is the most appropriate strategy for a client with an NG tube who is experiencing nausea and decreased gastric secretions?

A. Increase the suction pressure
B. Irrigate the NG tube with sterile water
C. Turn the client onto their side
D. Replace the NG tube with a new one

Correct answer: B

Rationale: Irrigating the NG tube with sterile water is the most appropriate strategy for a client with an NG tube experiencing nausea and decreased gastric secretions. This intervention helps in relieving blockages within the tube and can help reduce nausea by ensuring proper drainage. Increasing the suction pressure (Choice A) can lead to complications and should not be done without healthcare provider orders. Turning the client onto their side (Choice C) is a general measure for patient comfort but does not directly address the issue with the NG tube. Replacing the NG tube with a new one (Choice D) is not necessary unless there are specific indications like tube damage or dislodgement.

3. What are the common signs and symptoms of dehydration in the elderly?

A. Dry mouth, confusion, and decreased skin turgor
B. Increased heart rate and muscle cramps
C. Fever, rapid breathing, and increased urine output
D. Increased thirst and difficulty walking

Correct answer: A

Rationale: Corrected Rationale: Dehydration in the elderly is often signaled by dry mouth, confusion, and decreased skin turgor due to reduced fluid intake. Choice A is the correct answer as these are common signs and symptoms of dehydration in the elderly.\nIncorrect Rationales: Option B (Increased heart rate and muscle cramps) are more associated with conditions like hyperthyroidism or electrolyte imbalances rather than dehydration. Option C (Fever, rapid breathing, and increased urine output) are signs of other medical conditions such as infections or diabetes insipidus. Option D (Increased thirst and difficulty walking) can be seen in various situations but are not specific signs of dehydration in the elderly.

4. A nurse is caring for a client who is having difficulty voiding following the removal of an indwelling urinary catheter. Which of the following interventions should the nurse take?

A. Assess for bladder distention after 6 hours
B. Encourage the client to use a bedpan in the supine position
C. Restrict the client's intake of oral fluids
D. Pour warm water over the client's perineum

Correct answer: D

Rationale: The correct answer is to pour warm water over the client's perineum. This intervention can help stimulate voiding after catheter removal by promoting relaxation of the perineal muscles and increasing sensory input to the bladder. Assessing for bladder distention after 6 hours (Choice A) is important but not the initial intervention for difficulty voiding. Encouraging the client to use a bedpan in the supine position (Choice B) may not be effective in promoting voiding. Restricting the client's intake of oral fluids (Choice C) is not appropriate as hydration is important for urinary function.

5. How should a healthcare professional assess a patient with suspected deep vein thrombosis (DVT)?

A. Monitor for leg pain, swelling, and redness
B. Check for calf tenderness and administer anticoagulants
C. Check for discoloration and monitor oxygen saturation
D. Check for numbness and provide thrombolytic therapy

Correct answer: A

Rationale: Correct Answer: The correct way to assess a patient with suspected deep vein thrombosis (DVT) is to monitor for leg pain, swelling, and redness. These are common clinical manifestations of DVT. Choice B is incorrect because administering anticoagulants should be based on a confirmed diagnosis, not just suspicion. Choice C is incorrect because discoloration and oxygen saturation are not primary indicators of DVT. Choice D is incorrect because numbness is not a typical symptom of DVT, and thrombolytic therapy is not the first-line treatment for suspected DVT.
