Nursing Elites

1. Narrow therapeutic index medications:

• A. are drug formulations with limited pharmacokinetic variability.
• B. have limited value and require no monitoring of blood levels.
• C. have less than a twofold difference in minimum toxic levels and minimum effective concentration in the blood
• D. have limited potency and side effects.

Correct answer: C

Rationale: The therapeutic index is the ratio between the median lethal dose and median effective dose of a drug, indicating the safety margin. Narrow therapeutic index medications have a small difference between minimum toxic levels and minimum effective concentration in the blood, making them high-risk drugs that require close monitoring to avoid toxicity. Choice A is incorrect because pharmacokinetics refer to drug absorption, distribution, metabolism, and elimination, not the therapeutic index. Choice B is incorrect because narrow therapeutic index drugs necessitate monitoring due to their narrow margin of safety. Choice D is incorrect because narrow therapeutic index drugs do not necessarily have limited potency but are characterized by a small window between efficacy and toxicity.

2. The nurse is caring for a client scheduled for removal of a pituitary tumor using the transsphenoidal approach. The nurse should be particularly alert for:

• A. Nasal congestion
• B. Abdominal tenderness
• C. Muscle tetany
• D. Oliguria

Correct answer: A

Rationale: During the removal of a pituitary tumor using the transsphenoidal approach, nasal congestion is a significant concern as it can further obstruct the airway. This can be due to mucosal swelling, bleeding, or edema resulting from the surgery. Nasal congestion requires immediate attention to prevent airway compromise. Abdominal tenderness, muscle tetany, and oliguria are not directly associated with the pituitary gland or the transsphenoidal approach, making them incorrect choices. Abdominal tenderness is more common in abdominal or pelvic surgeries due to intra-abdominal issues. Muscle tetany is related to electrolyte imbalances or neuromuscular disorders, not specific to pituitary surgery. Oliguria is a concern in renal-related conditions, not typically in pituitary tumor surgeries.

3. Upon arrival at the emergency room, the client presents with severe burns to the left arm, hands, face, and neck. What action should take priority?

• A. Starting an IV
• B. Applying oxygen
• C. Obtaining blood gases
• D. Medicating the client for pain

Correct answer: B

Rationale: In a client with severe burns to the face and neck, airway assessment and supplemental oxygen are crucial. Therefore, applying oxygen is the priority to ensure adequate oxygenation for the client. This intervention takes precedence over other actions to stabilize the client's condition. Starting an IV for fluid resuscitation is the next appropriate step following ensuring oxygenation (Choice A). While pain management is important, it is a secondary priority after ensuring oxygenation and fluid resuscitation, making medicating the client for pain a later intervention (Choice D). Obtaining blood gases (Choice C) is not the immediate priority in this scenario and would typically be ordered by the healthcare provider based on the client's condition and response to initial interventions.

4. Lidocaine is a medication frequently ordered for the client experiencing

• A. Atrial tachycardia
• B. Ventricular tachycardia
• C. Heart block
• D. Ventricular bradycardia

Correct answer: B

Rationale: Lidocaine is used to treat ventricular tachycardia. This medication slowly exerts an antiarrhythmic effect by increasing the electrical stimulation threshold of the ventricles without depressing the force of ventricular contractions. It is not used for atrial arrhythmias; thus, answer A is incorrect. Answers C and D are incorrect because lidocaine does not slow the heart rate, so it is not used for heart block or bradycardia.

5. Which of the following attitudes is essential in a nurse who assists clients during crises?

• A. viewing crisis intervention as the first step in solving bigger problems
• B. wanting to help clients solve all problems identified
• C. taking an active role in guiding the process
• D. feeling that work requires identification with all of a client's problems

Correct answer: A

Rationale: Viewing crisis intervention as the first step in solving bigger problems is essential in a nurse who assists clients during crises. This approach focuses on addressing the immediate crisis first, which can potentially prevent the escalation of bigger problems. Wanting to help clients solve all problems identified (Choice B) may not be feasible or necessary during a crisis situation where immediate intervention is crucial. Taking an active role in guiding the process (Choice C) is important, but the primary focus should be on crisis intervention. Feeling that work requires identification with all of a client's problems (Choice D) may lead to a lack of focus on the immediate crisis at hand.
