Nursing Elites

1. 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.

2. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which clinical finding is most concerning?

• A. Peaked T waves on the ECG
• B. Bradycardia
• C. Muscle weakness
• D. Decreased deep tendon reflexes

Correct answer: A

Rationale: Peaked T waves on the ECG are the most concerning finding in a client with hyperkalemia. Hyperkalemia can lead to serious cardiac complications, including arrhythmias and cardiac arrest. Peaked T waves are a classic ECG finding associated with hyperkalemia and indicate the need for immediate intervention. Bradycardia, muscle weakness, and decreased deep tendon reflexes can also be seen in hyperkalemia, but the presence of peaked T waves signifies a higher risk of cardiac events, making it the most concerning finding in this scenario.

3. An adult female client with chronic kidney disease (CKD) asks the nurse if she can continue taking over-the-counter medications. Which medication provides the greatest threat to this client?

• A. Magnesium hydroxide (Maalox).
• B. Birth control pills.
• C. Cough syrup containing codeine.
• D. Cold medication containing alcohol.

Correct answer: A

Rationale: The correct answer is A: Magnesium hydroxide (Maalox). In clients with CKD, magnesium can accumulate to toxic levels due to decreased excretion by the kidneys. Therefore, it poses the greatest threat to this client population. Choice B, birth control pills, is not typically contraindicated in CKD. Choice C, cough syrup containing codeine, may require dose adjustments but is not the greatest threat. Choice D, cold medication containing alcohol, is a concern mainly in liver disease, not CKD.

4. The nurse provides feeding tube instructions to the wife of a client with end-stage cancer. The client's wife performs a return demonstration correctly but begins crying and tells the nurse, 'I just don't think I can do this every day.' The nurse should direct further teaching strategies toward which learning domain?

• A. Cognitive.
• B. Affective.
• C. Comprehension.
• D. Psychomotor.

Correct answer: B

Rationale: The correct answer is B: Affective. The affective domain involves feelings and emotions, which are significant factors in the wife’s ability to cope and perform the required care. In this scenario, the wife's emotional response indicates a need for further support and teaching strategies to address her emotional concerns and build her confidence. Choices A, C, and D are incorrect because the issue at hand is not purely cognitive (knowledge), comprehension (understanding), or psychomotor (physical skills), but rather an emotional response that falls under the affective domain.

5. A male client reports the onset of numbness and tingling in his fingers and around his mouth. Which lab test is important for the nurse to review before contacting the healthcare provider?

• A. Capillary glucose
• B. Urine specific gravity
• C. Serum calcium
• D. White blood cell count

Correct answer: C

Rationale: The correct answer is C: Serum calcium. Numbness and tingling in the fingers and around the mouth are indicative of hypocalcemia. Serum calcium levels should be reviewed as they play a crucial role in diagnosing and managing hypocalcemia. Option A, capillary glucose, is not relevant to the symptoms described. Option B, urine specific gravity, is not typically used to assess numbness and tingling. Option D, white blood cell count, is unrelated to the symptoms presented by the client.
