1. A client taking long-term steroids also has ranitidine prescribed. The nurse provides which explanation as to why these drugs are given together?
- A. Ranitidine reduces the risk of ulcers associated with steroids.
- B. Ranitidine decreases the risk of infection associated with steroids.
- C. Ranitidine decreases blood sugar elevations associated with steroids.
- D. Ranitidine reduces sodium retention associated with steroid usage.
Correct answer: A
Rationale: The correct answer is A. Ranitidine is prescribed with long-term steroids to reduce the risk of ulcers associated with steroid therapy. Although steroids can increase the risk of ulcers due to their effect on the gastrointestinal system, ranitidine works by reducing stomach acid production, thus helping to prevent ulcer formation. Choices B, C, and D are incorrect as ranitidine is not given to decrease the risk of infection, reduce blood sugar elevations, or reduce sodium retention associated with steroid usage.
2. A client with a history of seizures is being discharged home. Which instruction is most important for the nurse to provide?
- A. Take your medication as prescribed.
- B. Avoid driving until your condition is stable.
- C. Keep a seizure diary.
- D. Avoid alcohol consumption.
Correct answer: A
Rationale: The most important instruction for a client with a history of seizures being discharged home is to take their medication as prescribed. Consistent and timely intake of anti-seizure medication is vital in managing seizures and preventing episodes. While instructions like avoiding driving until the condition is stable, keeping a seizure diary, and avoiding alcohol consumption are important, none are as critical as ensuring proper medication adherence to control seizures effectively. Failure to take prescribed medications can lead to breakthrough seizures, compromising the patient's safety and seizure control.
3. The UAPs working on a chronic neuro unit ask the LPN/LVN to help them determine the safest way to transfer an elderly client with left-sided weakness from the bed to the chair. What method describes the correct transfer procedure for this client?
- A. Place the chair at a right angle to the bed on the client's left side before moving.
- B. Assist the client to a standing position, then place the right hand on the armrest.
- C. Have the client place the left foot next to the chair and pivot to the left before sitting.
- D. Move the chair parallel to the right side of the bed, and stand the client on the right foot.
Correct answer: D
Rationale: The correct method for transferring an elderly client with left-sided weakness from the bed to the chair involves moving the chair parallel to the right side of the bed and standing the client on the right foot. This technique provides a stable and safe transfer by utilizing the stronger side of the client to support the transfer. Choices A, B, and C are incorrect because placing the chair at a right angle to the bed on the client's left side, assisting the client to a standing position and placing the right hand on the armrest, and having the client pivot to the left before sitting do not address the client's left-sided weakness and may increase the risk of falls or injuries.
4. Based on this strip, what is the correct interpretation of this rhythm?
- A. Atrial fibrillation.
- B. Premature atrial fibrillation.
- C. AV block.
- D. Ventricular tachycardia.
Correct answer: A
Rationale: The correct interpretation of the rhythm strip is atrial fibrillation. This arrhythmia is characterized by an irregular heartbeat and the absence of distinct P waves. Choice B, premature atrial fibrillation, is incorrect as there is no indication of premature beats in the strip. Choice C, AV block, is also incorrect as there is no evidence of conduction delays between the atria and ventricles. Choice D, ventricular tachycardia, is not supported by the absence of wide QRS complexes typically seen in this arrhythmia.
5. A client is admitted with acute pyelonephritis. Which symptom should the nurse expect the client to report?
- A. Flank pain
- B. Pedal edema
- C. Hypotension
- D. Weight gain
Correct answer: A
Rationale: Flank pain is a classic symptom of acute pyelonephritis, which is a bacterial infection of the kidney. It occurs due to inflammation and irritation of the renal capsule, leading to pain in the flank region. Pedal edema (swelling in the feet and ankles) is more commonly associated with conditions like heart failure or kidney disease, not typically seen in acute pyelonephritis. Hypotension (low blood pressure) is a systemic symptom that may occur with severe infections but is not a specific hallmark of pyelonephritis. Weight gain is also not a typical symptom of acute pyelonephritis; instead, patients may experience weight loss due to decreased appetite and systemic effects of infection.
