Nursing Elites

1. The healthcare provider is assessing a client with left-sided heart failure. Which laboratory value should be monitored closely?

• A. Serum sodium of 135 mEq/L
• B. Serum potassium of 4.5 mEq/L
• C. Serum creatinine of 1.8 mg/dl
• D. Serum glucose of 200 mg/dl

Correct answer: C

Rationale: In a client with left-sided heart failure, monitoring serum creatinine is crucial to evaluate kidney function and fluid balance. Elevated creatinine levels can indicate impaired kidney function, which is common in heart failure due to decreased cardiac output and renal perfusion. Serum sodium levels (choice A) are important but are more closely associated with fluid balance and heart failure exacerbation. Serum potassium (choice B) is also important to monitor, but it is more closely linked to cardiac arrhythmias rather than kidney function. Serum glucose levels (choice D) are significant but are not the priority for monitoring in left-sided heart failure.

2. The nurse is preparing to administer an intramuscular injection to a client with muscle wasting in the gluteal region. What is the most appropriate site for the injection?

• A. Dorsogluteal site
• B. Ventrogluteal site
• C. Deltoid site
• D. Vastus lateralis site

Correct answer: D

Rationale: The vastus lateralis site is the most appropriate for an IM injection in a client with muscle wasting in the gluteal region. Administering the injection in the vastus lateralis ensures effective medication delivery due to muscle wasting in the gluteal region, preventing potential complications associated with the dorsogluteal or ventrogluteal sites, which may not be suitable in this specific client case. The deltoid site is mainly used for smaller volumes of medication and may not be ideal for this scenario.

3. 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.

4. A client with chronic obstructive pulmonary disease (COPD) is admitted with pneumonia. Which assessment finding is most concerning?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 24 breaths per minute
• C. Use of accessory muscles
• D. Inspiratory crackles

Correct answer: C

Rationale: The correct answer is C: 'Use of accessory muscles.' In a client with COPD and pneumonia, the use of accessory muscles indicates increased work of breathing. This finding is concerning as it may signal respiratory failure, requiring immediate intervention. Oxygen saturation of 90% (choice A) is low but not as immediately concerning as the increased work of breathing. A respiratory rate of 24 breaths per minute (choice B) is slightly elevated but not as critical as the use of accessory muscles. Inspiratory crackles (choice D) may be present in pneumonia but are not as indicative of impending respiratory failure as the increased work of breathing shown by the use of accessory muscles.

5. The healthcare provider is assessing a client with left-sided heart failure. Which laboratory value should be closely monitored?

• A. Serum sodium level
• B. Serum potassium level
• C. Serum creatinine level
• D. Serum glucose level

Correct answer: B

Rationale: In a client with left-sided heart failure, monitoring serum potassium levels is crucial. This helps in assessing kidney function and fluid balance. Elevated potassium levels can result from impaired kidney function, which is common in heart failure. Monitoring sodium levels (choice A) is important in heart failure but not specifically related to left-sided heart failure. Serum creatinine (choice C) reflects kidney function but is not the most critical value to monitor in this case. Serum glucose level (choice D) is important but not the priority when assessing left-sided heart failure.
