Nursing Elites

1. The nurse is assessing a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which laboratory value is most concerning?

• A. Serum sodium of 135 mEq/L
• B. Serum potassium of 4.0 mEq/L
• C. Serum bicarbonate of 18 mEq/L
• D. Serum glucose of 300 mg/dL

Correct answer: C

Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with COPD as it indicates metabolic acidosis, requiring immediate intervention. In COPD, patients often retain carbon dioxide, leading to respiratory acidosis. A low serum bicarbonate level suggests that the body is compensating for this respiratory acidosis by increasing bicarbonate levels to maintain balance. Therefore, a low serum bicarbonate level in this scenario is alarming. Choices A, B, and D are within normal ranges and not directly related to the acid-base imbalance seen in COPD.

2. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which intervention should the nurse implement first?

• A. Administer a bronchodilator as prescribed.
• B. Assess the client's respiratory rate.
• C. Assess the client's oxygen saturation.
• D. Elevate the head of the bed.

Correct answer: C

Rationale: Assessing the client's oxygen saturation is crucial in a client with COPD receiving supplemental oxygen to ensure adequate oxygenation. This assessment helps determine if the current oxygen therapy is effective or if adjustments are necessary. While administering a bronchodilator is important in managing COPD, assessing oxygen saturation takes precedence to address the client's immediate oxygen needs. Assessing the respiratory rate is also important but evaluating oxygen saturation provides more direct information about the client's oxygen status. Elevating the head of the bed can improve ventilation but is not the priority when assessing oxygen saturation in a client with COPD receiving supplemental oxygen.

3. For the past 24 hours, an antidiarrheal agent, diphenoxylate, has been administered to a bedridden, older client with infectious gastroenteritis. Which finding requires the nurse to take further action?

• A. Tented skin turgor
• B. Decreased bowel sounds
• C. Persistent diarrhea
• D. Dehydration

Correct answer: A

Rationale: The correct answer is A. Tented skin turgor is a sign of dehydration, which can be exacerbated by the use of antidiarrheals in clients with gastroenteritis. In dehydration, the skin loses its elasticity and becomes less resilient when pinched. Therefore, the nurse should take immediate action upon noticing tented skin turgor to prevent further complications. Choices B, C, and D are incorrect because decreased bowel sounds, persistent diarrhea, and dehydration are expected findings in a client with gastroenteritis who has been administered an antidiarrheal agent.

4. A female client reports she has not had a bowel movement for 3 days, but now is defecating frequent small amounts of liquid stool. Which action should the nurse implement?

• A. Digitally check the client for a fecal impaction
• B. Administer a laxative to stimulate bowel movement
• C. Increase fluid intake to soften stool
• D. Perform a digital rectal examination

Correct answer: A

Rationale: The correct action for the nurse to implement is to digitally check the client for a fecal impaction. In this scenario, the client's presentation of frequent small amounts of liquid stool after a period of no bowel movement suggests a possible impaction. By performing a digital examination, the nurse can assess for the presence of a blockage that may be causing the symptoms. Administering a laxative (Choice B) without assessing for impaction can worsen the situation. Increasing fluid intake (Choice C) is generally beneficial for bowel health but may not address the immediate issue of a potential impaction. Performing a digital rectal examination (Choice D) is similar to Choice A but is more focused on assessing the rectum itself rather than checking for an impaction.

5. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.
