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. The parents of a 6-year-old recently diagnosed with asthma should be taught that symptoms of an acute episode of asthma are due to which physiological response?

• A. Inflammation of the mucous membrane and bronchospasm
• B. Increased mucus production and airway obstruction
• C. Hyperinflation of the lungs and alveolar collapse
• D. Bronchoconstriction and airway inflammation

Correct answer: D

Rationale: The correct answer is D: Bronchoconstriction and airway inflammation. During an acute asthma episode, bronchoconstriction and airway inflammation occur, leading to difficulty breathing. Choices A, B, and C are incorrect. Inflammation of the mucous membrane and bronchospasm (Choice A) are part of the pathophysiology of asthma but do not fully explain the symptoms during an acute episode. Increased mucus production and airway obstruction (Choice B) are also seen in asthma but are not the primary cause of acute symptoms. Hyperinflation of the lungs and alveolar collapse (Choice C) are not typical features of an acute asthma episode.

3. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which laboratory value should be closely monitored before the procedure?

• A. Serum creatinine of 2.0 mg/dl
• B. Serum potassium of 5.5 mEq/L
• C. Serum calcium of 8.0 mg/dl
• D. Hemoglobin of 12 g/dl

Correct answer: B

Rationale: A serum potassium level of 5.5 mEq/L is concerning in a client with ESRD scheduled for hemodialysis as it indicates hyperkalemia, which can lead to serious cardiac complications. Hyperkalemia can be exacerbated during hemodialysis, making it crucial to closely monitor serum potassium levels before the procedure. Monitoring serum creatinine, serum calcium, or hemoglobin levels is important in managing ESRD but is not the immediate focus before hemodialysis. Therefore, option B is the correct choice.

4. When administering ceftriaxone sodium (Rocephin) intravenously to a client, which finding requires the most immediate intervention by the nurse?

• A. Stridor
• B. Nausea
• C. Headache
• D. Pruritus

Correct answer: A

Rationale: The correct answer is A: Stridor. Stridor indicates bronchospasm, a serious reaction that can compromise the client's airway. Immediate intervention is crucial to prevent further respiratory distress. Nausea, headache, and pruritus are potential side effects of ceftriaxone but are not as immediately life-threatening as airway compromise indicated by stridor.

5. An adult female client is admitted to the psychiatric unit because of a complex handwashing ritual she performs daily that takes two hours or longer to complete. She worries about staying clean and refuses to sit on any of the chairs in the day area. This client's handwashing is an example of which clinical behavior?

• A. Addiction
• B. Phobia
• C. Compulsion
• D. Obsession

Correct answer: C

Rationale: The client’s handwashing ritual is a compulsion, a repetitive behavior driven by the need to reduce anxiety associated with an obsession. In this case, the client's need to wash her hands excessively stems from an obsession with cleanliness, leading to the compulsive behavior of extensive handwashing. 'Addiction' (Choice A) involves a dependence on a substance or behavior, not related to this scenario. 'Phobia' (Choice B) is an intense fear of a specific object or situation, not applicable here. 'Obsession' (Choice D) refers to persistent and intrusive thoughts, while the handwashing behavior in this case is the compulsive action taken to alleviate the anxiety related to the obsession.
