1. The drug of choice to decrease uric acid levels is:

• A. prednisone (Colisone)
• B. allopurinol (Zyloprim)
• C. indomethacin (Indocin)
• D. hydrochlorothiazide (HydroDiuril)

Correct answer: B

Rationale: The correct answer is allopurinol (Zyloprim) as it is a xanthine oxidase inhibitor that decreases uric acid formation. Allopurinol is commonly used to manage gout by lowering uric acid levels. Prednisone is a corticosteroid used to decrease inflammation, not to lower uric acid levels. Indomethacin is an analgesic, anti-inflammatory, and antipyretic agent, but it is not the drug of choice for lowering uric acid levels. Hydrochlorothiazide is a thiazide diuretic used to treat hypertension and edema, not to decrease uric acid levels.

2. Which physiologic mechanism best describes the function of the sodium-potassium pump?

• A. active transport
• B. diffusion
• C. filtration
• D. osmosis

Correct answer: A

Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.

3. Which of the following needs immediate medical attention and emergency intervention? The client who:

• A. complains of sharp pain upon taking a deep breath and excessive coughing.
• B. exhibits yellow, productive sputum, low-grade fever, and crackles.
• C. has a shift of the trachea to the left, with no breath sounds on the right.
• D. has asthma and complains of an inability to catch her breath after exercise.

Correct answer: C

Rationale: Choice C is indicative of a tension pneumothorax, which is considered a medical emergency. The respiratory system is severely compromised, and venous return to the heart is affected. The mediastinal shift is to the unaffected side, indicating a critical situation that requires immediate intervention to prevent further deterioration. This condition can rapidly progress to a life-threatening state, necessitating prompt medical attention. Choices A, B, and D do not present with life-threatening conditions requiring emergency intervention. Choice A mentions symptoms of pleurisy, which may be painful but not immediately life-threatening. Choice B describes symptoms of bronchitis, which may require medical attention but not of an emergent nature. Choice D reflects a common complaint in asthma but does not suggest an immediate life-threatening situation unless severe respiratory distress is present.

4. What is the most common cause of acute renal failure?

• A. Shock
• B. Nephrotoxic drugs
• C. Enlarged prostate
• D. Diabetes

Correct answer: A

Rationale: The correct answer is 'Shock.' Acute renal failure is commonly caused by inadequate blood flow to the kidneys, which can occur in cases of shock. This leads to decreased kidney function and potential kidney damage. While nephrotoxic drugs can also cause acute renal failure, shock is the primary and most common cause. An enlarged prostate may lead to obstructive uropathy but is not the most prevalent cause of acute renal failure. Diabetes is typically associated with chronic kidney disease rather than acute renal failure.

5. When discussing the child's wishes for future care, it is important for the nurse to first identify what the child knows about the disease and his prognosis. Factors such as the perceived severity of the illness will be significant in planning for end-of-life care. If the child does not understand the disease process or prognosis, the plan of care would not be effective or realistic. In addition, asking a child about desired interventions in the event of cardiac or respiratory arrest would not be an appropriate initial area of questioning. If the child does not understand the disease process, these questions may seem frightening or threatening. While exploring the child's belief about death would be important, it would not be the initial area of discussion and should be guided by the child rather than the nurse.

• A. What the child knows about the disease and his prognosis.
• B. How the child would like to handle the plan of care.
• C. What interventions the child would like in the event of cardiac or respiratory arrest.
• D. What the child believes about death.

Correct answer: A

Rationale: When discussing the child's wishes for future care, it is essential to first determine what the child understands about the disease and his prognosis. This information is crucial for planning appropriate end-of-life care. If the child lacks comprehension of the illness and its prognosis, any care plan discussed would be ineffective and unrealistic. Inquiring about desired interventions during cardiac or respiratory arrest is not the initial step, as it may cause distress if the child lacks understanding. While exploring the child's beliefs about death is significant, it should not be the primary focus initially and should be approached based on the child's readiness, not the nurse's agenda. Therefore, the correct first step is to assess what the child knows about the disease and his prognosis.
