Nursing Elites

1. A client is brought to the emergency department by a neighbor. The client is lethargic and has a fruity odor on the breath. The client’s arterial blood gas (ABG) results are pH 7.25, PCO2 34 mm Hg, PO2 86 mm Hg, HCO3 14 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: The correct answer is 'Metabolic acidosis.' Metabolic acidosis is characterized by a low pH (<7.35) and a low bicarbonate level (HCO3 <22 mEq/L). In this case, the client's ABG results show a pH of 7.25 and an HCO3 level of 14 mEq/L, indicating metabolic acidosis. The PCO2 of 34 mm Hg is normal, ruling out respiratory acidosis or alkalosis. The PO2 of 86 mm Hg is also within the normal range and is not indicative of a respiratory problem. Therefore, the client is experiencing metabolic acidosis based on the ABG results provided.

2. Polyethylene glycol–electrolyte solution (GoLYTELY) is prescribed for a hospitalized client scheduled for a colonoscopy. The client begins to experience diarrhea after drinking the solution. Which action by the nurse is appropriate?

• A. Calling the physician
• B. Administering a cleansing enema
• C. Documenting the diarrhea in the medical record
• D. Giving intravenous replacement fluids in large amounts

Correct answer: C

Rationale: The correct action by the nurse in this situation is to document the diarrhea in the medical record. Polyethylene glycol–electrolyte solution (GoLYTELY) is a bowel evacuant used to cleanse the bowel before a colonoscopy. It is expected to cause mild diarrhea, which is a normal response to the medication. The diarrhea helps clear the bowel in preparation for the procedure. Calling the physician is not necessary unless there are complications. Administering a cleansing enema or giving intravenous replacement fluids in large amounts are not appropriate actions as they are not indicated for managing the expected diarrhea caused by GoLYTELY.

3. A client is starting urinary bladder training. Which statement should the nurse include in this client’s teaching?

• A. Use the toilet when you first feel the urge, rather than at specific intervals.
• B. Try to consciously hold your urine until the scheduled toileting time.
• C. Initially try to use the toilet at least every half hour for the first 24 hours.
• D. The toileting interval can be increased once you have been continent for a week.

Correct answer: B

Rationale: In urinary bladder training, the client should be taught to try to consciously hold their urine until the scheduled toileting time. This helps in training the bladder to hold urine for longer periods. Option A is incorrect because the goal is to consciously hold urine, not void immediately. Option C is incorrect as toileting at least every half hour may not promote bladder training. Option D is incorrect as increasing the toileting interval should be based on the client's comfort and progress, not just after being continent for a week.

4. A nurse cares for a client with diabetes mellitus who is prescribed metformin (Glucophage) and is scheduled for an intravenous urography. Which action should the nurse take first?

• A. Contact the provider and recommend discontinuing the metformin.
• B. Keep the client NPO for at least 6 hours prior to the examination.
• C. Check the client’s capillary artery blood glucose and administer prescribed insulin.
• D. Administer intravenous fluids to dilute and increase the excretion of dye.

Correct answer: A

Rationale: Metformin can cause lactic acidosis and renal impairment as the result of an interaction with the dye. This drug must be discontinued for 48 hours before the procedure and not started again after the procedure until urine output is well established. The client’s health care provider needs to provide alternative therapy for the client until the metformin can be resumed. Keeping the client NPO, checking the client’s blood glucose, and administering intravenous fluids should be part of the client’s plan of care, but are not the priority, as the examination should not occur while the client is still taking metformin.

5. The client who has a history of Parkinson's disease for the past 5 years is being assessed by the nurse. What symptoms would this client most likely exhibit?

• A. Loss of short-term memory, facial tics, and grimaces, and constant writhing movements.
• B. Shuffling gait, masklike facial expression, and tremors of the head.
• C. Extreme muscular weakness, easy fatigability, and ptosis.
• D. Numbness of the extremities, loss of balance, and visual disturbances.

Correct answer: B

Rationale: Parkinson's Disease, a common neurologic progressive disorder in older clients, is characterized by symptoms such as shuffling gait, masklike facial expression, and tremors of the head and hands. Choice A is incorrect as symptoms like loss of short-term memory, facial tics, and constant writhing movements are not typically associated with Parkinson's disease. Choice C is incorrect as extreme muscular weakness, easy fatigability, and ptosis are more indicative of other conditions like myasthenia gravis. Choice D is incorrect as numbness of the extremities, loss of balance, and visual disturbances are not classic symptoms of Parkinson's disease.
